  Not long ago, the official announcement of Changsha Education Bureau that "starting from April 25th, Changsha Primary School will resume classes at the wrong peak" made many parents of primary school students relieved. In sharp contrast to the joy of parents of primary school students, it seems difficult for parents of kindergarten students who have started school irregularly to calm down: their children will go to primary school in the second half of the year, and now they will enter May, and they will stay at home and watch TV and play games. Will it affect the connection between young and old? The time of children in large classes in the park is shortened, and the training institutions are not yet open. How can parents help their children to make a good connection at home? The reporter interviewed many senior kindergarten directors and well-known primary school principals in Changsha to give advice to parents.

  Stories alleviate the anxiety of young children’s connection, and parents buy textbooks to learn first.

  Although the Ministry of Education explicitly proposed "zero starting point" enrollment, at this time last year, many parents transferred their children to a young connecting institution to learn some primary school knowledge in advance to adapt to the schedule of primary schools because they were worried that their children would lose at the starting line. However, this year, affected by the epidemic, not only the start time of kindergarten has not been clear, but also the training institutions listed in the final approval list are waiting. Undeniably, the lack of home cooperation and training institutions to help, the pressure of young convergence naturally falls more on parents.

  In such a special period, the days passed quietly while waiting, which made the heart of Ms. Shen, the parents of large kindergarten students, more and more tight. She originally planned to send her children to a training class when the school started in the spring to make up for the young connection. However, the school start time has not been fixed, and she and her husband have to work during the day, so the children can only be taken care of by the elderly, resulting in the children being in a state of stocking almost all day. "I’m really worried that the child will suddenly switch from playing now to studying after school. Can he adapt?"

  Like Ms. Shen, Ms. Chen has her troubles. In the second half of this year, her children will become first-grade primary school students, which makes her happy and worried. Happily, children will enter a new stage of life; Worryingly, the kindergarten starts late, and the young connection pressure on her and her husband is not small. "This semester’s kindergarten study is basically abandoned, and how to prepare for the child’s young connection" tests Ms. Chen and her husband. In order to relieve anxiety, she bought a textbook for the first grade and last semester, and studied it with her husband first.

  "We can’t be ignorant of his learning content." After some research, Ms. Chen is confident that her children can master this knowledge. She told reporters that from the end of February to the present, in accordance with the principle of combining work and rest, in addition to arranging Chinese, mathematics and English knowledge study for children, she also interspersed poetry reading, picture book reading, calligraphy practice, skipping rope, roller skating and other sports. "It is only tentative to let children do some knowledge reserves in advance, without any assessment." Ms. Chen said that studying in advance may make children more confident about going to primary school, but after entering primary school, children may not listen carefully because they understand.

  The survey is worried that children can’t keep up with their studies, and over 60% of parents will report to the young bridging course.

  At present, how to do a good job of connecting young children is not only an urgent problem for parents of kindergarten students in large classes, but also the focus of education departments. In order to understand parents’ understanding and confusion about the connection between young and old children and their adaptability in primary schools, so as to grasp the future direction of parents’ education, not long ago, under the guidance of Yuelu District Education Bureau, Bocai Education Group distributed questionnaires to 2,102 kindergarten parents in the form of online questionnaires. The survey shows that many parents have different puzzles about the connection between young and young.

  Many parents are worried about whether their children can smoothly adapt to the study and life of primary schools after attending primary schools, such as whether they can concentrate on lectures, whether they can adapt to the teaching methods of primary school teachers, whether they can take good care of themselves, and whether they can get along well with their classmates. There are also parents who worry from themselves, such as not being able to pick up their children too early after school; There are also a few parents’ worries from schools, such as campus safety and campus violence.

  When answering the question "You will enroll your child in the young bridging course", over 60% of parents said "Yes". Among them, 58.75% parents think it is "very necessary" because they are worried that their children can’t keep up with their studies; 6.47% of parents think that other children have gone to school and their children can’t fall behind. Another 20.08% of parents said that they would not report, on the grounds that they would teach.

  In addition, many parents who participated in the survey have doubts about what should be prepared and done in the early childhood bridging education, so that children can smoothly transition from kindergarten to primary school, and how to cultivate their various habits and skills.

  "Through the feedback of literature and questionnaires, we can know that parents’ understanding of young convergence has made great progress compared with previous years. They no longer simply think that young convergence is only to teach children to read and count, but more importantly, to cultivate children’s good study habits and living habits. However, parents still have doubts about specific measures." The relevant person in charge of Bocai Primary School said in the investigation report.

  Young convergence of views ≠ Parents should be patient and wait for the children who have just entered the school.

  So, what can parents do to help their children make a good connection? Well-known primary school principals and senior public kindergarten directors in Yuelu District expressed their views.

  Peng Qingqing, director of the Eighth Kindergarten of Yuelu Preschool Education Group, believes that when parents help their children to make young connections, they should first correctly define young connections. She said, "Young convergence ≠ Learning primary school content, learning quality training is far more important than learning knowledge and skills preparation. " She said, "From the perspective of the turn of education in the world today, it is from knowledge-based education to the cultivation of learning quality. Among them, learning quality refers to the positive attitude and good behavior tendency of children in the process of activities, including learning interest, learning habits, learning attitude and learning ability. "

  Peng Qingqing suggested that parents should not only pay attention to the cultivation of their children’s learning quality, but also make their children well prepared for psychology, life, material, knowledge and sports. For example, help children prepare psychologically and stimulate their yearning for primary school life. When preparing for sports, you can help your child practice skipping, playing ball, running and other sports. "When entering primary school, it is necessary to carry out a sports compliance test, and the child’s physique, physical fitness and athletic ability must keep up. Studies have proved that skipping rope and racqueting can also cultivate children’s concentration. "

  Long Sheng, the principal of Bocai Boarding Primary School, said that children in the young convergence stage have some characteristics and needs, and if parents understand them, they can be more patient. "6-year-old children’s cognitive ability and development level are not consistent. It is normal to have differences before and after. There is no right or wrong, and temporary backwardness should be allowed. In the face of many changes, the first psychological nutrition that children need in the young transition period is: a sense of security. " Longsheng said that the second demand of children at this stage is role model demand. They need to learn how to learn, how to manage their emotions and how to deal with problems in life, and this learning comes from an example, and parents are the best models.

  "The basis of all learning abilities in the future is determined by whether you get enough psychological nutrition before the age of 7. Safety, example and recognition … … These are all psychological nutrition that children need. If you get it, children will naturally have the vitality to explore and learn new things; If he doesn’t get it, he will spend a lot of life energy to find unsatisfied psychological needs. Therefore, in the key steps of children’s growth, parents should be slower. Slow means feeding the child well first and giving him physiological and psychological nutrition; Slowness means creating high-quality parent-child relationship and teacher-student relationship first; Slow means waiting for a child to let his nature grow well. "

  While advocating "slow education" and advising parents to be patient, Longsheng also put forward the view of "critical period", that is, growth is more important than children’s grades. "In such a critical period, what is the most critical, to cultivate? Years of educational work have made us realize that children should be cultivated when entering primary schools ‘ Freedom in rules ’ … … The process of helping children establish rules and habits is not simple and rude ‘ Pull weeds ’ , but should be ‘ Planting crops by throwing seedlings ’ The process. On the basis of rules, give them freedom of mind and thought. " Long Sheng said.

  Worried that children can’t adapt to primary school? Try these six tricks.

  What should parents do to help their children adapt to primary school study and life? Li Hui, the principal of the first primary school in Yuelu District, combined with 30 years of primary education practice, summed up the experience of six tricks to make children adapt to primary school life quickly.

  These six tricks are: playing "family drama of primary school life" with children; One-day tour of primary school campus with children; Adjust your child’s schedule one month in advance; Adapt to not taking a nap; Develop three exclusive chores for children and cultivate their awareness of completing tasks on their own initiative; Establish a special study area for children and cultivate their concentration.

  Taking the "Family Drama of Primary School Life" as an example, Li Hui suggested that parents can use 10 minutes to open a small family class every day, and family members can play the role of teachers and students in class, play games and make friends, so that children can learn to listen, learn to express and make friends on their own initiative. In terms of cultivating children’s awareness of actively completing tasks, she said that parents can arrange some tasks for their children every day, such as sweeping the floor, watering flowers, folding quilts and taking out garbage. After practicing for a month, children will build up the consciousness of actively completing tasks, so they don’t have to worry about their procrastination in doing homework and doing things, so as to avoid the trouble of parents nagging their children to do homework every day and urging them to "hurry up" in the future.

News 1+1 Can the Yangtze River Protection Law be cured after the Yangtze River has been "sick" for more than ten years?

  The Law on the Protection of the Yangtze River was officially implemented on March 1st. Can it provide a new model for China’s future legislation based on ecosystem? How should the Yangtze River Economic Belt really develop green?

  News 1+1 connects with Chang Jiwen, deputy director of the Institute of Resources and Environmental Policy of the State Council Development Research Center, to analyze what changes will be brought by the Yangtze River Protection Law.

  Q The Yangtze River is "sick". Is the Yangtze River Protection Law "medicine"?

  Chang Jiwen, Deputy Director of the Institute of Resources and Environmental Policy of the State Council Development Research Center:The Yangtze River basin has been "sick" in the past few years or even more than ten years. The problems of illegal fishing, pollution of the Yangtze River basin by chemical enterprises and smoke pollution are urgently needed to be solved by the Yangtze River Protection Law. If it is not to the point where it is impossible to cure or not to cure, the Yangtze River Protection Law will not be promulgated. Because in the past, there were various laws related to the protection of water bodies, such as the Law on the Prevention and Control of Water Pollution, the Law on Soil and Water Conservation, the Law on Forest Protection, etc., but the effect was not too great, so only a watershed law could be specially formulated to solve it.To stipulate a special system and stricter legal responsibilities to stop illegal activities..

  Q Yangtze River Protection LawWill it be more effective for the shortcomings in the ecological and environmental protection management of the Yangtze River Basin in the past?

  Chang Jiwen, Deputy Director of the Institute of Resources and Environmental Policy of the State Council Development Research Center:I thinkWill be more effectively governed.. ①The punishment for the administrative counterpart is stricter.In the past, you may have done some acts without being punished. Now it is different. For example, if you engage in illegal fishing in production, you may confiscate fishing gear, including fishing boats, and be fined more than 10,000 yuan and less than 50,000 yuan. If you adopt methods such as poisonous fish, electric fish and fried fish, you may be fined more than 50,000 yuan and less than 500,000 yuan. If you violate the criminal law, you may be investigated for criminal responsibility. If some restaurants advertise in the name of selling wild fish, they will also be punished, with a maximum penalty of 2 million yuan. ②Stricter legal responsibilities have been imposed on local officials.If local officials do not seriously ensure the implementation of the law, they may face accountability. The highest accountability is to take the blame and resign, as well as dismissal and dismissal. This is the stricter legal responsibility after the strictest Environmental Protection Law of People’s Republic of China (PRC) in history.

  Q Why should the Yangtze River protection start with a 10-year fishing ban?

  Chang Jiwen, Deputy Director of the Institute of Resources and Environmental Policy of the State Council Development Research Center:The 10-year fishing ban has been scientifically demonstrated. On the basis of scientific argumentation, the state issued a fishing ban period, which was consolidated by the Yangtze River Protection Law. The Law on the Protection of the Yangtze River also stipulates a 10-year period for the investigation and evaluation of ecological biodiversity in the Yangtze River basin, including the restoration of plant and animal systems.It is beneficial to the ecological stability and biodiversity of the Yangtze River basin, and lays a solid foundation for the sustainable development of the Yangtze River basin in the future.. Its bottom line is to give priority to protection and green development, and the Yangtze River cannot be developed and utilized in a way that undermines the ability of sustainable development, so it must be protected first.After it is restored, the Yangtze River will be used in a sustainable way.This is the current rule of law model.

  Q Will economic development be affected if fishing is banned for 10 years?

  Chang Jiwen, Deputy Director of the Institute of Resources and Environmental Policy of the State Council Development Research Center:Economic development will be affected in the short term, but in the long run, it will definitely promote economic development in a long term. ① In the short term, taking Jianli County, Jingzhou City, Hubei Province as an example, the transformation of fishermen is very painful. Because local finance can’t provide much money to support farmers’ transformation and production conversion, there are some difficulties in the short term. (2) in the long run, will not suffer. At present, the biggest impact is on the polluting economy and the ecologically destructive economy. Therefore, it will take some time for local transformation. We must grasp the rhythm and be patient. We must not be impatient and engage in polluting projects whenever there are difficulties. This is unacceptable. Therefore, if the work is in place and the pace of transformation is appropriate, it can promote the green competitiveness of cities in the Yangtze River Basin at home and even around the world. Now, we have been talking about green development, low-carbon development and circular development. Cities in the Yangtze River Basin should take this opportunity to enhance their competitiveness in the integration of green and low-carbon.

  Q How to grasp the balance between protection and development when formulating the detailed rules for the development of the Yangtze River Basin at the local level?

  Chang Jiwen, Deputy Director of the Institute of Resources and Environmental Policy of the State Council Development Research Center:(1) strictly enforce the law, strictly implement the Yangtze River Protection Law, so that the requirements of the law can be implemented in production and life. 2 Actively and scientifically guide the green transformation. Although the foundation of transformation in some places is very weak, you have to transform. The sooner you transform, the more active you are. All localities should complement each other’s industries, form their own industries with advantages and characteristics, and carry out innovation.

Multiple positive signals frequently appear, and real estate policies are accelerated to adjust and optimize.

  Recently, the central and local governments at all levels have voiced their voices one after another, adjusted and optimized real estate policies in a timely manner, and made good use of the policy toolbox to better meet the rigid and improved housing needs of residents.

  A few days ago, Zhengzhou issued the "Notice on Further Promoting the Stable and Healthy Development of the Real Estate Market in Our City", proposing 15 optimization policies, such as canceling the sales restriction and implementing "recognizing the house but not the loan".

  The insiders believe that stabilizing the construction industry and the real estate industry plays an important role in promoting the economic recovery. Previously, some adjustment policies proposed by the Ministry of Housing and Urban-Rural Development and the People’s Bank of China will accelerate, and the real estate market is expected to usher in a steady development trend.

  On August 4th, the National Development and Reform Commission and other four departments held a press conference with the theme of "laying a good combination of macro policies and promoting high-quality economic development". Yuan Da, Deputy Secretary-General of the National Development and Reform Commission and Director of the Comprehensive Department, said that policies and measures such as promoting the renovation of urban villages in mega-cities and the construction of "flat and emergency dual-use" public infrastructure, and orderly expanding the issuance scale of real estate investment trusts (REITs) in the infrastructure sector have been introduced and implemented one after another, and other policies are also being pushed forward, providing strong policy support for sustained economic recovery.

  "Strengthen policy reserves in better meeting the rigid and improved housing needs of residents and actively expanding effective investment, and continuously release the potential of ultra-large-scale market." Yuan Da said.

  Zou Lan, director of the Monetary Policy Department of the People’s Bank of China, said that he would continue to support the smooth operation of the real estate market, and reiterated that he would continue to implement the loan support plan for Baojiaolou until the end of May 2024, and steadily push forward the rental housing loan support plan in pilot cities. At the same time, guide banks to adjust the interest rate of existing individual housing loans in an orderly manner according to law.

  It is worth mentioning that this is not the first time that the People’s Bank of China has proposed to adjust the "stock mortgage interest rate". On July 14th, at the press conference of financial statistics for the first half of 2023 held by the State Council Office, Zou Lan said that the interest rate of existing mortgage loans issued in previous years in China was still at a relatively high level. "Next, in accordance with the principles of marketization and rule of law, the People’s Bank of China supports and encourages commercial banks and borrowers to negotiate independently to change the contractual agreement, or to issue new loans to replace the original stock loans."

  Subsequently, on August 1st, the People’s Bank of China and the State Administration of Foreign Exchange also explicitly proposed in the working meeting in the second half of 2023 that the differentiated housing credit policy should be accurately implemented due to the city’s policy, and the interest rate and down payment ratio of individual housing loans should continue to decline to better meet the rigid and improved housing needs of residents. Guide commercial banks to adjust the interest rate of existing individual housing loans in an orderly manner according to law.

  Zhang Bo, president of 58 Anjuke Research Institute, said that at present, the downward direction of the interest rate of existing individual housing loans has been made clear, which is an important measure to reduce the demand-side cost of buying houses. On the one hand, adjusting the interest rate of stock mortgage can reduce the economic burden of the people who have bought houses, and play a certain role in promoting their living expenses. On the other hand, it can also reduce the phenomenon of early repayment of loans, which is conducive to the stability of high-quality mortgage assets of banks.

  In fact, in addition to the frequent statements of the financial sector, the housing and construction sector has also made a clear statement. Ni Hong, Minister of Housing and Urban-Rural Development, pointed out at a recent enterprise symposium that it is necessary to continue to consolidate the trend of stabilization and recovery of the real estate market, vigorously support the demand for rigid and improved housing, and further implement policies and measures such as reducing the down payment ratio and loan interest rate for the first home purchase, reducing taxes and fees for the purchase of improved housing, and "recognizing housing without repaying loans" for individual housing loans.

  Among these policies, the policy of "recognizing the house without recognizing the loan" has received great attention. Li Yujia, chief researcher of the Housing Policy Research Center of the Guangdong Provincial Urban Planning Institute, said that "there is no need to recognize a house" means that when determining the loan ratio, commercial banks do not look at the previous loan records, but only determine whether there is a house under the family name. This means that the "sell one, buy one" improved home buyers will enjoy the treatment of the first home purchase.

  Policies such as "recognizing the house without recognizing the loan" are expected to usher in more breakthroughs in the second half of the year. On August 3, Zhengzhou announced the implementation of the policy of "recognizing houses but not loans", which is considered to have a strong demonstration significance. First-tier cities such as North, Shanghai, Guangzhou and Shenzhen have also indicated that they will pay close attention to the implementation work in conjunction with relevant departments in light of the actual situation of the local real estate market, vigorously support and better meet the rigid and improved housing needs of residents, and promote the stable and healthy development of the real estate market.

Military Internet of Things: Building a "tight encirclement" for War Support

In what way human society lives, it fights in what way. With the maturity of the military Internet of Things, it is possible for weapons and equipment to "see", "communicate", "think" and listen to "command". Silent objects seem to have wisdom, which will provide important support for the integrated joint operational command and decision-making system and will be the real "tight encirclement" in the future war environment.


Realize seamless battlefield perception and improve battlefield transparency.


As early as 1999, when the Internet of Things was just born, it was called sensor network. The birth of the sensor system of military Internet of Things can be traced back to the Vietnam War in 1960s. In order to monitor the people and vehicles coming and going on the Ho Chi Minh Trail, the US military used an unattended "tropical tree" vibration sensor. When there is a target moving, the sensor can detect the vibration and sound source information generated by the target, and then transmit the data to the command center, so as to command the air fighter to bomb the target.


The military Internet of Things focuses on the battlefield situation awareness, intelligent analysis and judgment, action process control and other links, so that the system can operate effectively in all directions, full-time domain and full spectrum, thus breaking the "fog of war" and comprehensively improving system capabilities based on information systems. Using the core technology of military Internet of Things-radio frequency identification technology, ordinary and low-cost equipment can also effectively obtain battlefield information and transmit it in real time through the network. For example, the "smart dust" developed by the US military has all the functions from information collection, processing to sending, although it is only the size of gravel. This will bring a new revolution to information acquisition: on the one hand, it can eliminate the blind spot of reconnaissance, realize the "seamless" perception of the battlefield and improve the transparency of the battlefield; On the other hand, the military Internet of Things can bring all personnel, weapons and support materials on the battlefield into the network. Any sensor on the network node can be connected with various reconnaissance and monitoring systems on satellites and airplanes to obtain the spatial positioning ability of the target that it does not have, so as to realize the perception and be positioned.


The military Internet of Things can also realize the accuracy of battlefield perception, that is, to establish an all-factor, all-process comprehensive information chain from the automatic perception of the battlefield from the sensor to the shooter, data transmission, command and decision, and fire control, so as to realize the reconnaissance of enemy forces’ deployment, weapons and equipment configuration, movement state, reconnaissance of operational terrain, defense facilities and other environments, accurate perception of battlefield information such as their own position protection and force dynamics, and joint cooperation of large-scale weapons platforms and various forces and weapons.


With the development of military internet of things technology, in the future information battlefield, military information network will be integrated with military internet of things, providing a brand-new means for information acquisition and processing. At present, the military of western developed countries attaches great importance to the development of military Internet of Things, and regards it as an important research field of sensor networks, and various innovative military Internet of Things platforms emerge one after another. The U.S. military has successively carried out research and application of a series of military sensor network systems, such as "Rumbas" system for remotely monitoring the battlefield environment, "Sand Line" system for monitoring the movement of weapon platforms, and "Wolf Pack" system for detecting electromagnetic signals. Japan, Britain, Italy, Brazil and other countries and armies have also shown strong interest in the military IOT network, and have launched research work in the military application field of wireless sensor networks.


Implementing transparent command in the whole process to improve the efficiency of operational decision-making


The military Internet of Things connects various military elements in the military field, such as things and things, things and people. Every combat unit, every firepower unit, every soldier and every weapon is tagged with RFID (Radio Frequency Identification), and every combat action of the troops can be transmitted to the command center through the wireless data communication network, thus realizing the transparent command and control of the whole combat action and improving the efficiency of operational decision-making.


Shorten the command cycle. The future information-based war will be a high-speed, high-precision and high-intensity war, with the sudden outbreak of the war, the rapid transformation of combat styles, the increased flow of material, energy and information on the battlefield, and the changeable flow direction. The relationship between various operational factors is complex, especially the application of the Internet of Things technology and the large number of information-based weapons and equipment put into the battlefield, which greatly shortens the process of obtaining intelligence information, transmitting information, making up your mind, implementing operational actions and evaluating operational effects. For example, the application of information transmission system based on military Internet of Things technology can greatly shorten the process of battlefield intelligence information transmission and greatly improve the speed of information transmission; Through the real-time monitoring of the battlefield, accurate target positioning information can be provided to the fire control and guidance system, and the command cycle of "observation-positioning-decision-action" can be shortened, thus making the command faster and more flexible.


Improve battlefield awareness. Applying the Internet of Things technology to the military field will make the battlefield intelligence information more accessible, faster in transmission and more scientific in processing and application, thus deepening the understanding of the battlefield. If the Internet of Things technology is applied to reconnaissance and early warning equipment, assisting reconnaissance satellites with real-time reconnaissance and real-time transmission capabilities, battlefield surveillance TV systems, unmanned aerial vehicles, etc., a large number of battlefield information can be collected all-weather, all-time, timely and accurately, so as to correctly recognize the battlefield. At the same time, the application of military internet of things will provide material conditions for commanders to command in real time. Commanders can get a panoramic view of the whole battlefield situation through the information display system of the command center, and countless digital links connected with the large database of the command center will extend to every corner of the battlefield, transmitting the positions, actions and achievements of the enemy and our troops to the command center in real time, forming a constantly updated comprehensive shared battlefield situation map, on which commanders can make decisions, quickly make up their minds, make correct responses to changes in the situation and command troops to fight in real time.


Implement stable command. The application of command information system with military Internet of Things technology as the core can realize the integration of acquisition, transmission, processing and application of battlefield information, and the seamless connection between all links can be realized. In particular, the command information system networked by military Internet of Things technology is network-like. Even if one channel is hard-destroyed and soft-killed by the enemy, other channels can work, so that battlefield information can be continuously obtained, transmitted, processed and used, effectively avoiding the situation that the troops will lose control when the combat command system is destroyed in the past, and enabling commanders to conduct stable command of the military operations. At present, the armed forces of western developed countries are seizing the development opportunity, vigorously developing the military Internet of Things, and building the future battlefield sensing nerve.


Fully control the war supply line and improve the accuracy of support.


Military Internet of Things has unlimited potential, and its popularization and application in the field of logistics support will help to realize "dynamic precision" support. During the Iraq war, Tommy Felix, then commander of the US Central Theater, ordered that any materials entering the theater under his jurisdiction must be tagged with RFID, so that he could get a panoramic view of the battlefield dynamic logistics without any effort.


Improve the ability of dynamic adaptive logistics support. The Internet of Things seems to be a perfect technology tailored for military logistics, which can effectively avoid the blindness of logistics work. With the breakthrough of radio frequency identification technology, two-dimensional bar code technology and intelligent sensing technology, the Internet of Things can provide a convenient and flexible solution for automatically obtaining information such as materials in storage, transportation and use. In the process of various military operations, the military Internet of Things can provide appropriate equipment and supplies to the combat troops at accurate locations and at accurate times, so as to avoid unnecessary confusion, trouble and waste caused by redundant materials rushing to the combat area. At the same time, it can make decisions according to the changes of battlefield environment, coordinate, control, organize and implement logistics support independently, and has adaptive logistics support ability. In addition, the military Internet of Things has realized the intelligence of military equipment. Through a large number of sensors, weapons and equipment can obtain battlefield information such as battlefield situation and enemy threat in real time, so as to respond in time and improve battlefield survivability; Through the embedded diagnostic sensor chip, the operator and maintenance point can know the intact condition of each part of the equipment in time, and realize the accuracy of battlefield maintenance.


Strengthen the precise control of combat materials. The electronic tag technology adopted by the military Internet of Things was first applied to the military. During the first Gulf War, American troops transported about 40,000 containers of weapons and equipment to the war zone. However, due to unclear signs, a lot of equipment lost cannot be found, which consumes huge war resources. Twelve years later, during the Iraq war, the US military installed high-tech RF satellite chips on every container shipped to the Gulf region, and placed readers at important material transportation intersections and storage areas, which realized the whole-course tracking of personnel, equipment and materials, made the material supply and management quite transparent, greatly improved the effectiveness of military logistics support, and finally saved billions of dollars. With the maturity of RFID tag technology and the reduction of cost, the military Internet of Things can be fully applied to single weapons, thus strengthening the management of weapons and equipment, and helping to find weapons and equipment that are extremely threatening and lost on the battlefield.


Improve the safety of supply lines. The logistics system based on the military Internet of Things has the characteristics of networking and nonlinear structure, and has strong anti-interference and anti-attack ability. It can not only accurately grasp the whole process of transporting materials from the factory to the foxhole in front, but also provide danger warning, deploy tasks for transport vehicles on the way and optimize transportation routes. In particular, it can integrate logistics support operations with the whole digital battlefield environment, realize the integration of logistics support and combat operations, enable logistics commanders to make decisions at any time or even in advance, greatly enhance the flexibility and crisis control ability of logistics operations, and fully guarantee the safety of logistics transportation.

Lured into illegal smuggling by "high salary", people who returned to China surrendered to tell the story of "electric fraud nightmare" in Myanmar.

[Global Times reporter Fan Wei Hu Yuwei special correspondent Jiang Bohuai] Recently, many China students believed in the temptation of getting rich and were tricked into losing contact with Myanmar, which once again aroused strong concern among domestic people about the problem of illegal smuggling. Although these lost students were finally found after many efforts, the evil phenomenon of luring others to sneak out of the country and engage in illegal activities still exists, and some people still have illusions about the false "gold rush dream". Recently, Yang, a self-confessed person who was deceived and smuggled abroad for nearly two years, told the Global Times reporter about his tragic experience of inhuman torture abroad. Yang told the Global Times reporter that he hoped to use his personal experience to warn people who had the same fantasies as him not to make the same mistakes again.

"When he lifted his underwear on his back and thighs, the scars deeply embedded in his skin shocked all the policemen present," a policeman at the entry-exit frontier inspection station in Ruili, Yunnan, who participated in receiving Yang, told the Global Times reporter that at the moment when he saw Yang show his scars, he and his colleagues around him could not believe that such a tragic experience had happened to a young man who was only 18 years old.

And the beginning of all this, just because of an overseas "gold rush" message.

Yang comes from a county in Guizhou, but he always has a dream of getting rich one day at a young age. One day in December 2020, he accidentally received a short message from abroad, which said that a company in Myanmar was recruiting salesmen. "As long as you can surf the Internet, you can chat with customers on your mobile phone and promote your products, you can easily earn 100,000 yuan a month! Food, shelter, and round-trip air tickets … "Yang told the Global Times reporter that after several days of careful consideration, he finally failed to resist the temptation of high salary and planned to take a trip outside while he was young. So I immediately got in touch with the other party, agreed on a good time, and sneaked abroad under the arrangement of the other party.

"But it doesn’t feel right when you get there. It doesn’t look like a place where you can make money," Yang said. After arriving in Myanmar, he went with the car to a "company" hidden in an unknown mountain. Although the connector claimed to be a "company", it was just a few iron houses built sporadically on the grassy grass, and the environment was very poor.

Before his previous contact showed up, he was taken to a dark room and forced to hand over his mobile phone, bank card and ID card. "When I first arrived in Myanmar at night, the wind outside made a creaking noise on the iron sheet. In the dormitory of two dozen people, the double-decker iron bed would make a harsh noise as soon as it turned over, and a pale yellow light would light up in a small toilet. I couldn’t sleep over and over in bed, and my heart was not practical, "Yang recalled the night when he first arrived in Myanmar.

The next day, the "company" manager led Yang to the place of work. "I asked what it was, and the person who took the class told me that it was fraud through online social software. Before leaving the country, my contact always told me that I was engaged in’ promotion’ work after arriving in Myanmar, and did not disclose that I wanted to engage in fraud. "Yang said that he immediately refused, but five or six big men rushed out of the inner room and dragged him into the inner room, followed by a burst of punching and kicking. Subsequently, Yang was detained by gunmen and restricted his personal freedom until he signed a work contract with the company a week later, but he lost his freedom and dignity since then. Not only did I not get the so-called "high salary" at the beginning, but I was also intimidated and brainwashed to "go to work" to engage in telecom fraud.

Yang recalled that the "company" manager asked him to complete the work tasks of the day every day before he got off work. Every day, "colleagues" are dragged to the inner room and beaten up, or handcuffed and electrocuted, and shouts are often heard from the inner room. This happens to everyone who can’t finish the task, and he is not spared.

"One day, because I didn’t complete the task arranged by the company, I was asked by the manager of the’ company’ to take off my clothes in public, kneel on the ground, and then beat my back, ass and thighs with a whip, leaving a deep imprint. In a short time, my back was beaten raw and bloody, and I could smell the faint smell of blood in the surrounding air. Half an hour later, perhaps because I was tired from playing, or because I thought I was still of use value, the manager of the’ company’ stopped waving the whip in his hand and threatened me that if I didn’t get results within a week, I would dig out my kidney and sell it! Speaking of the scene that he had been abused, Yang was still a little afraid.

In order not to be whipped again by the manager, Yang worked overtime every day and exhausted his efforts to complete the tasks arranged by the "company". I thought this life would be easier. Unexpectedly, due to the serious lack of long-term overtime sleep, there was a mistake in the work, so the manager of the company slapped him continuously, which led to the rupture of the eardrum of the left ear. The manager also pointed a gun at Yang’s head to warn him not to do it again.

In the days of living an inhuman life, Yang also thought about running away, but because his ID card had been taken away and he was a stranger, he couldn’t escape at all. "The company is located in the barren hills and there are guards at the door, and they can’t let me escape. Someone tried to escape, but they were quickly recovered. What was waiting for them was a beating and then put in jail," Yang said.

Finally, because of his mediocre performance in "work", Yang was sold as "goods" by the "company" managers to a number of companies engaged in fraud. But each time, they suffered from worse environment and more brutal abuse.

Yang said that during his two years of smuggling abroad, he was whipped and injured in more than 20 places, especially leaving a 15cm-long scar on his calf. In the past two years, he wanted to leave countless times, but every time he mentioned this to the manager of the company, he was beaten up and couldn’t get out of bed for two or three days. Because of his physical pain, Yang dared not mention leaving again. Every day, he lived like a walking corpse.

The last "company" where Yang worked was located in a mountain near Muse City, Myanmar. After coming to this "company", Yang still engaged in the same "work" as the first two companies. The only difference was that the manager of this "company" told him that as long as he could pay 60,000 yuan, he could let him leave and regain his freedom. The hope of life prompted Yang to start making fraudulent phone calls day and night, hoping to earn enough money to be redeemed as soon as possible and escape from here as soon as possible.

In February of this year, Yang, who had experienced a nightmare life in Myanmar for nearly two years, finally saved enough money to be redeemed and regained his freedom. At the first time he left the company, Yang came to Ruili Port to surrender to the police at the border checkpoint on duty at the port.

"It feels really good to go home. I can accompany my parents and do what I want. Even if I take a class at home, it is better than there. In the future, I want to open my own grilled fish shop and stop thinking about the dream of getting rich overnight." The police at the entry-exit frontier inspection station in Ruili, Yunnan Province told the Global Times reporter that when he met Yang, he kept expressing his regret for easily listening to others smuggling out of the country, and at the same time he was glad that he had the opportunity to become the kind of person who escaped from inhuman torture. At present, Yang has been taken criminal compulsory measures in accordance with the law for allegedly crossing the country (border), and the case is being handled.

In recent years, some people have been tricked into engaging in online gambling and telecom fraud abroad by the high salary trap. These cross-border illegal activities have triggered a series of chain social problems in Southeast Asian countries such as Myanmar, the Philippines and Thailand, such as murder, kidnapping and human trafficking. In order to crack down on a series of criminal activities, on March 20th, a trilateral meeting on human trafficking jointly held by the Ministry of Public Security of the People’s Republic of China, the National Police of the Republic of Myanmar and the National Police Department of Thailand was held in Bangkok, Thailand, which will jointly crack down on transnational crimes such as human trafficking and telecom fraud.

According to the China Embassy in Myanmar, on March 23rd, Chen Hai, Ambassador of China to Myanmar, also held a meeting with Lieutenant General Soto, Deputy Prime Minister and Minister of the Interior of Myanmar, on stepping up efforts to crack down on illegal cross-border criminal activities such as cyber fraud and gambling.

Ambassador Chen Hai pointed out that illegal cross-border criminal activities such as online fraud and gambling harm people’s interests and safety, undermine social stability and order, and affect China-Myanmar exchanges and cooperation. Recently, many incidents of Chinese personnel crossing the border to Myanmar have the background of illegal activities such as online fraud and gambling in Myanmar. It is hoped that Myanmar will attach great importance to the seriousness and harmfulness of related activities, further strengthen coordination and cooperation with China, intensify efforts to crack down on related illegal activities, and create a clear environment for China-Myanmar friendly cooperation.

Suotu said that Myanmar is well aware of the dangers of illegal activities such as online fraud and gambling, attaches great importance to the position that China has repeatedly stated, and has stepped up efforts to crack down. In view of the recent continuation of illegal activities in Myanmar, Myanmar is willing to join forces with China and other relevant neighboring countries to resolutely crack down and effectively curb them, and jointly safeguard the friendly cooperation between China and Myanmar and the safety of people’s lives and property.

Leading Chinese modernization with new development concept

  Idea is the forerunner of action. Whether the development concept is right or not fundamentally determines the development effectiveness and even success or failure. General Secretary of the Supreme Leader emphasized in the Party’s Report to the 20th CPC National Congress that "implementing the new development concept is the only way for China to develop and grow in the new era". This important conclusion provides an important follow-up for the new era and new journey to promote Chinese modernization.

  Since the 18th National Congress of the Communist Party of China, the CPC Central Committee with the Supreme Leader as the core has put forward a series of major theories and concepts on economic and social development, among which the new development concept is the most important and important. Promoting Chinese-style modernization is a great exploratory undertaking, and there are still many unknown fields that need us to explore boldly in practice. Therefore, it is of great significance to lead Chinese modernization with new development concepts.

  The road of innovation and development of modernization

  Innovation is the first driving force to lead development, and innovation and development focus on solving the problem of development motivation. General Secretary of the Supreme Leader pointed out: "International economic competition and even comprehensive national strength competition, in the final analysis, is the competition of innovation ability. Whoever can make the first move in innovation will be able to take the initiative. " The innovation-driven development strategy implemented in China involves scientific and technological innovation, enterprise innovation, product innovation, market innovation, brand innovation, etc. The core is scientific and technological innovation. The key to Chinese modernization lies in scientific and technological modernization.

  In promoting the new journey of Chinese modernization, innovation and development need to be exerted in the following aspects.

  First, there must be new breakthroughs in the development of the digital economy. Developing digital economy is of great significance, and it is a strategic choice to grasp the new opportunities of the new round of scientific and technological revolution and industrial transformation. In the era of digital economy, the digitalization of information and knowledge makes data a key factor of production, computing power a new driving force for economic and technological development, and the Internet, big data, artificial intelligence, cloud computing and the real economy are deeply integrated. This is a new track for economic and technological competition in the world, and it is also the focus of innovation and development of modernization. It is necessary to further strengthen the innovation of digital technology, improve the level of Internet and artificial intelligence with the enhancement of computing power, and promote the deep integration of digital economy and real economy on this basis. It is necessary to promote the digitalization of industries on the basis of digital industrialization, empower various industries with the support of a new generation of information technology, promote the digitalization and intelligent transformation and upgrading of traditional industries, and rely on the technology and platform provided by the digital economy to promote the innovation of new industries and their technologies, promote the digitalization of enterprise operation, and promote the digitalization of government governance and social management.

  The second is to strive to achieve high-level scientific and technological self-reliance. Practice has repeatedly told us that key core technologies can’t be bought, bought or discussed. Only by mastering key core technologies in our own hands can we fundamentally guarantee national economic security, national defense security and other security. In the past, the advantage of late-developing countries was mainly about introducing new international technologies. However, the closer the late-developing countries are to modernization, the more difficult it is to introduce key core technologies from developed countries. At present, China’s scientific and technological innovation has shifted from following to running, running side by side and leading. The so-called parallel running is to be in line with international standards, that is, to exert strength in the same frontier direction of science and technology; The so-called leading means connecting with the future, becoming a global leader in important scientific and technological fields, becoming a pioneer in frontier cross-fields, becoming a major scientific center and innovative highland in the world. We must adhere to the principle that science and technology are the primary productive force, talents are the primary resource and innovation is the primary driving force, and carry out the strategy of rejuvenating the country through science and education, strengthening the country through talents and innovation-driven development in depth, so as to enhance the endogenous driving force of innovation and development and realize the self-reliance and self-reliance of high-level science and technology.

  Third, deploy innovation chain around the industrial chain. At present, the global division of labor has entered the stage of intra-product division, and most of the production links of products are distributed in different countries and regions. International competition is mainly manifested in the competition of industrial chain and supply chain. There are two main situations in the layout of China’s industrial chain, one is the layout of China’s industrial chain supply chain, and the other is the layout of China’s industries participating in the global industrial chain. The decisive factors affecting the layout of industrial chain involve the level of science and technology, cost and market conditions. At present, some developed countries have cut off the supply of high-tech links to China enterprises, resulting in a number of industrial chains in which China participates. This is both a challenge and an opportunity for China’s industrial chain supply chain. We should focus on cultivating leading industries with core competitiveness, deploy innovation chain around the industrial chain, develop strategic emerging industries with high scientific and technological content, strong market competitiveness, great driving effect and good economic benefits, truly put scientific and technological innovation on industrial development, promote short-board industries to supplement chains, extend chains of advantageous industries, upgrade chains of traditional industries and build chains of emerging industries, and strive to build a modern industrial system.

  The road of coordinated development of modernization

  Coordination is the inherent requirement of sustained and healthy development, and coordinated development focuses on solving the problem of unbalanced development. The main contradiction in our society has been transformed into the contradiction between the people’s growing need for a better life and the unbalanced development, which is a historic change that has a bearing on the overall situation. China is a big developing country, and the imbalance between urban and rural areas, regions and industries is prominent. To solve these unbalanced problems, we should coordinate at a high level, not at a low level in all aspects.

  In promoting the new journey of Chinese modernization, coordinated development needs to focus on two aspects.

  On the one hand, it promotes the synchronous development of new industrialization, informationization, urbanization and agricultural modernization. China’s modernization is very different from that of western developed countries. Western developed countries are a "series" development process. It took more than 200 years for industrialization, urbanization, agricultural modernization and informatization to develop in sequence. We want to catch up with others and get back the "lost 200 years", which determines that China’s development must be a "parallel" process, and industrialization, informationization, urbanization and agricultural modernization are superimposed. "Synchronization of the four modernizations" is a successful experience of China’s development, a new era and a new journey, and this experience needs more abundant content. First, efforts should be made to build a modern industrial system, including the high-end, intelligent and green development of manufacturing industry and the construction of a new high-quality and efficient service industry system. Second, informatization has entered a new stage of accelerating digital development and building a digital China, and it needs to actively integrate into a new round of scientific and technological revolution and industrial transformation to promote the upgrading of industrial base. Third, the new urbanization has been continuously promoted, and the urbanization of agricultural transfer population has been promoted in accordance with the requirements of new urbanization with people as the core. It is necessary to promote cities and towns to have urban functions and the ability to undertake urban industrial transfer and urbanization of agricultural transfer population, and to promote urban modernization, make it the source of modernization in various regions, increase the supply of modern urban elements, and realize the integration of production, city, culture and ecology.Promote the coordinated development of large, medium and small cities. The fourth is to build an agricultural power in the short board of agricultural modernization, build a high-quality and efficient modern agricultural industrial system that is compatible with the upgrading of household consumption, improve the quality and added value of agricultural products through biological and digital technology innovation, and realize high-quality and efficient agriculture, livable and suitable for rural areas, and rich farmers.

  On the other hand, it is to promote regional coordinated development. Report to the 20th CPC National Congress, the Communist Party of China, put forward that "regional coordinated development strategy, major regional strategy, main functional area strategy and new urbanization strategy should be thoroughly implemented, the layout of major productive forces should be optimized, and a regional economic layout and land space system with complementary advantages and high-quality development should be constructed". For the late-developing areas, it is necessary to fill in the shortcomings according to the requirements of "four modernizations synchronization". We emphasize the promotion of regional coordinated development, which is embodied in the economic field. First, we promote the integration of industrial development. For example, the first-developing region distributes the industrial chain of its advantageous industries to the later-developing regions to form an integrated industrial system; The second is to promote the integration of scientific and technological innovation. For example, as a science and technology innovation center, the first-developing region will arrange the innovation results to the late-developing region to realize industrialization; The third is to build a two-way "enclave economy". For example, the science and technology (industry) park will be built in the late-developing areas in the first-developing areas, and the R&D institutions will be built in the late-developing areas; Fourth, the integrated construction of traffic information facilities, so as to shorten the distance between the late-developing areas and the early-developing areas; Wait a minute.

  The road to green development of modernization

  Green is a necessary condition for sustainable development and an important embodiment of people’s pursuit of a better life. Green development focuses on solving the problem of harmony between man and nature. Since modern times, the modernization of western countries has mostly gone through the stages of wanton plunder of natural resources and vicious destruction of ecological environment. While creating huge material wealth, it often causes serious problems such as environmental pollution and resource depletion. China’s per capita energy resource endowment is seriously insufficient, and accelerating development faces more energy resources and environmental constraints, which determines that China cannot take the old road of western modernization. Respecting nature, conforming to nature, protecting nature and promoting harmonious coexistence between man and nature are the distinctive features of Chinese modernization.

  To promote the modernization of harmonious coexistence between man and nature, it is necessary to practice Lucid waters and lush mountains are invaluable assets’s ideas. General Secretary of the Supreme Leader pointed out that green mountains and green rivers are not only natural wealth, ecological wealth, but also social wealth and economic wealth. Protecting the ecological environment means protecting natural value and increasing natural capital, and protecting the potential and stamina of economic and social development, so that green mountains and green rivers can continue to play their ecological and economic and social benefits. At the same time, people’s needs for a better life are more extensive. People expect to breathe fresh air, drink clean water, eat safe food, live in a livable environment, and truly feel the tangible environmental benefits brought by economic development.

  On the new journey of Chinese modernization, we will better promote green development. First, we will accelerate the green transformation of development mode, promote green and low-carbon economic and social development, and unswervingly follow the civilized development path of production development, affluent life and good ecology; Second, deepen the energy revolution, accelerate the planning and construction of a new energy system, and actively and steadily promote carbon neutrality in peak carbon dioxide emissions; The third is to promote the improvement of urban and rural human settlements, implement urban renewal actions, strengthen urban infrastructure construction, build livable, resilient and smart cities, and make rural areas basically have modern living conditions; Fourth, we should promote carbon reduction, pollution reduction, greening and growth, accelerate technological progress and industrial restructuring, and support high-quality development with a high-quality ecological environment.

  The road to modernization and open development

  Opening-up is the only way for a country to prosper and develop, and opening-up development focuses on solving the problem of internal and external linkage of development. Only an open China will become a modern China. At present, the world has undergone a great change in the past century, and the trend of anti-globalization has risen, and unilateralism and protectionism have risen markedly. In this context, to promote modernization, we need to further deepen reform and opening up, enhance the endogenous power and reliability of domestic large-scale circulation, improve the quality and level of international circulation, and firmly grasp the leading role of development in our own hands.

  On the new journey of promoting Chinese modernization, the ways to promote high-level opening up mainly include the following aspects. First, greater efforts should be made to attract and utilize foreign capital. It is necessary to rely on China’s super-large-scale market advantage to attract global resource elements through domestic circulation, not only to keep high-quality foreign capital, but also to attract more high-quality foreign capital to improve the quality and level of trade and investment cooperation. The corresponding measures include: expanding market access, reasonably reducing the negative list of foreign investment access, and increasing the opening up of modern service industry; Comprehensively optimize the business environment, implement the national treatment of foreign-funded enterprises, promote fair competition, ensure that foreign-funded enterprises participate in government procurement, bidding and standard setting on an equal footing according to law, and increase the protection of intellectual property rights and the legitimate rights and interests of foreign investment. The second is to form an open and innovative ecology with global competitiveness. Breaking the technical blockade and carrying out open innovation is a reliable path. Efforts should be made to introduce innovative resources, especially innovative talents, and make breakthroughs in core technologies and key technologies with independent intellectual property rights that are at the forefront of the world and lead industrial innovation. In this regard, it is particularly important to build an open and innovative ecology. It is necessary to steadily expand the institutional opening of rules, regulations, management and standards for international trade and investment, and improve the intellectual property protection system. The third is to cultivate new comparative advantages and competitive advantages. Now, China’s competitive advantage in participating in the international circulation has changed, and it is necessary to speed up the construction of an important talent center and an innovative highland in the world to form a comparative advantage in international competition for talents. The fourth is to coordinate development and security in opening up. The more open,The more we should pay attention to safety, we should coordinate development and safety, and enhance our own competitiveness, open supervision and risk prevention and control capabilities.

  The road of shared development of modernization

  Sharing is the essential requirement of Socialism with Chinese characteristics, and sharing development focuses on solving social fairness and justice. Chinese-style modernization is the modernization of common prosperity for all people. We should not promote common prosperity after realizing modernization, but promote modernization and common prosperity simultaneously. We insist on realizing the people’s yearning for a better life as the starting point and the end result of modernization, make efforts to safeguard and promote social fairness and justice, make efforts to promote the common prosperity of all people, and resolutely prevent polarization. Now, China has built a well-off society in an all-round way, which has historically solved the problem of absolute poverty, and it needs to further solve the problem of relative poverty in the new journey.

  Chinese-style modernization should not only create higher efficiency than capitalism, but also safeguard social fairness more effectively, and better realize the balance, promotion and unity of efficiency and fairness. Common prosperity is a long-term goal, which needs a process and cannot be achieved overnight. Its long-term, arduous and complex nature should be fully estimated. Common prosperity is not simultaneous prosperity, nor uniform egalitarianism.

  On the new journey of Chinese modernization, to promote common prosperity and shared development in a down-to-earth manner requires both inclusive development and continuous deepening of reform.

  In promoting inclusive development, we should take effective measures against the gap between urban and rural areas and regions, paying special attention to the development of rural areas and late-developing areas; In view of the income gap between industries, it is necessary to adjust the industrial structure based on the objective evaluation of various industries by the market; In view of the income gap caused by the difference of human capital level, it is necessary to strengthen education and training to improve the level of human capital.

  In the aspect of continuously deepening reform, it is necessary to build a coordinated system of primary distribution, redistribution and third distribution, and properly handle the relationship between efficiency and fairness. First, give full play to the basic role of primary distribution, build an income distribution system that reflects efficiency and promotes fairness, improve the policy system of distribution according to factors, explore various channels to increase the factor income of low-and middle-income people, and increase the property income of urban and rural residents through multiple channels. Second, give full play to the regulatory role of redistribution, strengthen the regulation of taxation, social security and transfer payment, improve the basic public service system, improve the level of public services, promote the equalization of basic public services, enhance their balance and accessibility in urban and rural areas and regions, improve the social security system and expand the coverage of social security. The third is to improve the third distribution mechanism and develop social welfare undertakings such as charity.

  In a word, Chinese-style modernization is a socialist modernization led by the Communist Party of China (CPC), which not only has the common characteristics of modernization in all countries, but also has the characteristics of China based on its own national conditions. On the new journey of Chinese modernization, we should implement the new development concept completely, accurately and comprehensively, promote high-quality development, and comprehensively promote the great rejuvenation of the Chinese nation with Chinese modernization.

Intelligent research and development

If an enterprise wants to transform intelligent manufacturing, it must first start from the root of product innovation, transform the serial R&D process into a closed-loop intelligent R&D process that is continuously improved according to the user’s needs, perceive the user’s needs and make flexible adjustments, and at the same time integrate the emerging enabling technologies related to intelligent manufacturing to form a product R&D cycle from user to user. That is to say, the analysis of market and user-related data begins at the stage of product design demand analysis, which includes the direct participation of users in the process of product customization based on their own preferences, and the feedback of relevant operating data during the use of products to guide the process of improving the original design scheme, forming an intelligent R&D process of continuous optimization.
 
 
「 1. Eight elements of intelligent research and development 」

 
The intelligent R&D process reflects the change in design history from designing for users, to helping users design, to users designing for themselves. Therefore, intelligent R&D must be based on the highly intelligent integration of design information, production information, user’s use and feedback information, from the process of intelligent demand generation to the acquisition of basic design data, from the intelligent user’s participatory design to the direct transformation into production information and implementation. In order to realize these changes, intelligent R&D must be supported by eight elements.
 
1) Establish a unified multidisciplinary collaborative R&D platform.
 
First of all, the development of intelligent products generally spans multiple professional and technical fields and has a variety of key technical characteristics, involving a high degree of cross-discipline and integration. At the same time, the diversified needs of users also make the product structure and function very complicated, and IT embedded software technology has gradually become the core part of the product, which requires the cooperation of many disciplines such as machinery, electricity and software.
 
This requires enterprises to establish a top-level architecture that can integrate R&D systems and tools in all different professional disciplines within the enterprise, and form a unified multidisciplinary collaborative R&D platform that can comprehensively manage all professional R&D elements in the product life cycle.
 
The platform can not only manage the professional drawings, process and material information, but also manage the product function, performance, quality, indicators and their generation process, and integrate programming and management, simulation, optimization, innovation, quality and other tools, so that the R&D system can quickly and efficiently apply these tools, so as to carry out differentiated, high-performance and high-quality product intelligent R&D.. On this basis, knowledge engineering will be used to accumulate knowledge in the process of enterprise R&D, and the ability of serial product development will be formed.
 
2) Establish a digital prototype to realize simulation-driven innovation.
 
The core of intelligent R&D is to establish a digital prototype of the product, which is used to support the overall design and structural design, cooperate with the process design, and support the project team to carry out parallel product development.
 
The main functions of establishing digital prototype include tolerance size analysis, interference check, etc., as well as weight characteristic analysis, motion analysis and ergonomics analysis. In addition, the digital prototype can also provide data information of product assembly analysis, including assembly unit information, assembly level information, etc., to ensure the simulation of product assembly sequence, assembly path, ergonomics, assembly process and working hours. The digital prototype can also be used to evaluate the process, including machining method, machining accuracy, tool path and so on, to realize the CAM simulation of the prototype and the process planning based on the three-dimensional digital prototype.
Digital prototype also plays an important role in the sales stage of products, which can provide vivid dynamic demonstration effect and static product data for product promotion. Through the lightweight technology of three-dimensional model, enterprises can conveniently and flexibly use the original digital prototype model to provide decomposition drawings and schematic diagrams for product training, and can also provide rapid variant and derivative design of similar products to meet the needs of market quotation and rapid organization of bidding and production.
 
In addition, on the basis of digital prototype, enterprises can also establish virtual prototype for system integration and simulation verification, which can reduce physical tests, reduce research and development costs, shorten research and development cycle and realize simulation-driven design. At the same time, simulation technology can be combined with test management to improve the confidence of simulation results.
 
In addition, in order to ensure the reliability of products, we must fully consider the engineering elements in the whole life cycle of products, such as process planning, manufacturing, assembly, inspection, sales, use, maintenance and scrapping of products. By using concurrent engineering and DFX technology, the performance, quality, manufacturability, assemblability, testability, product service and price of products in different stages are comprehensively evaluated as early as possible in the design stage, so as to optimize product design and ensure product quality.
 
3) adopt standardized and modular design methods to improve the product customization ability.
 
User-centered intelligent research and development will inevitably face the diversity of user needs, which requires enterprises to have flexible product variant design capabilities and form standardized, modular and serialized product development capabilities. As the basic unit of product design, module is the carrier of product knowledge. Modularization and knowledge reuse of products can moderately reduce design risks, improve product reliability and quality, and greatly reduce design cost and design cycle. In addition, it can also shorten product procurement cycle, logistics cycle and manufacturing cycle, and reduce product procurement cost, logistics cost, manufacturing cost and product after-sales service cost. Therefore, it is particularly important to have the ability of product standardization and modular design.
 
Modular design is to analyze the functions of products with different functions or the same function, different performances and different specifications in a certain range, classify them and design a series of functional modules. Through the selection and combination of modules, different product combinations can be formed to meet the requirements of variant products with different functions and specifications.
 
Modular design mode can improve design reuse and reduce cost. The combination of R&D management platform and modular design means makes this design mode even more powerful. The implementation of modularization and serialization will produce a large number of product modules and configuration rules, and the amount of data is huge. It needs to be managed by R&D management platform to realize the order and structure of design modules, thus ensuring the accuracy of data and the reusability of knowledge.
 
4)MBD/MBE design information is highly integrated with production information.
 
MBD (model-based definition) can define manufacturing information and design information into the three-dimensional digital model of products. MBD not only describes the geometric information of design, but also defines three-dimensional product manufacturing information and non-geometric management information (product structure, dimension and tolerance labeling, BOM, etc.), so that the information exchange between design and manufacturing can maintain an effective connection without completely relying on the integration of information systems. MBD breaks down the barrier of design and manufacturing, and makes the features of design and manufacturing be easily interpreted by computers and engineers, thus effectively solving the problem of integration of design and manufacturing.
 
After MBD model is regarded as a unified "engineering language", the application of MBE (model-based enterprise) can be further promoted. The data contained in the design model can be effectively transmitted in the process, supply, manufacturing and maintenance services. Through a highly consistent data model, a two-way data flow is formed between PLM, ERP and MES, which makes the manufacturing and subsequent processes highly automated and forms a digital "closed loop" of the whole value chain.
 
5) Innovative design integrating additive manufacturing and topology optimization technology.
 
Different from the traditional empirical design mode, the topologically optimized product model is the optimal topological model that meets the performance requirements under given load, working conditions and other constraints. It is a new design method to determine and remove the materials that do not affect the rigid parts through topology optimization, and realize the lightweight of the parts on the basis of meeting the functional and performance requirements. However, topology optimization technology has better effect only when manufacturing process constraints are not considered. Therefore, although engineers have designed a product model with unique structure and high performance through topology optimization, they often give up the advantages of lightweight and high performance because of manufacturability.
 
With the appearance and mature application of additive manufacturing technology, this big problem can be solved well. Additive manufacturing technology can help enterprises get rid of the limitation of traditional manufacturing technology of reducing materials and equal materials, and design products according to the most ideal structural form, making it possible for products to have "functional priority". Therefore, additive manufacturing makes the value of topology optimization technology fully play, and the integration of them innovates the design and manufacturing process, which is a subversive change for traditional manufacturing industry.
 
6) Design review of application of virtual reality and augmented reality technology
 
Virtual reality and augmented reality technology are the bridge between virtual products and real products. By applying virtual reality and augmented reality technology, the design scheme of products and related attribute information of products can be intuitively displayed and experienced in the initial stage of products and before the physical prototype test. Moreover, in the virtual space, it is also convenient for designers to communicate collaboratively, making the whole design review process more convenient and effective, and at the same time, the problems existing in the design process can be more intuitively discovered.
 
7) Establish wide-area collaborative research and development based on cloud.
 
In intelligent R&D, based on the Internet, the products and services of enterprises will gradually change from one-way technological innovation, production of products and services to the market, waiting for customer experience, to active contact with users’ service terminals, benign interaction and collaborative development of products, and the subject of technological innovation will turn into users. Its innovation, consciousness and demand run through the production chain, affecting the decision-making of design and production.
Designers will become the organizers of gathering resources among consumers, users and producers, and will play a driving role under the huge network of design and production chain, and will no longer independently undertake all product innovation work. Intelligent R&D will be based on collaborative research and development with suppliers, partners and customers in the cloud, so that everyone can participate in open innovation. Internet-based collaborative design cloud platform can bring together industrial designers and R&D engineers with professional skills from all over the world online to enter the intelligence database, and quickly organize large-scale collaborative operations, which can help manufacturing customers to complete industrial product R&D and design efficiently and conveniently. Once there is an urgent need to be solved, it can be submitted and published at any time on the platform. The platform can help the demanders find high-quality solutions through timely matching and pushing them to the intelligence library with relevant experience, and the whole process is coordinated and controlled.
 
8) Closed-loop product research and development based on digital twins to drive product innovation.
 
Product R&D has evolved from focusing on the initial design stage of the product life cycle to focusing on the whole product life cycle. The simulation, testing and experiment in the design stage and the collection and utilization of relevant data in the product operation and service stage have played an important role in product optimization and innovation, which has improved the speed and quality of prototype design.
 
It depends on the vigorous development of sensing, Internet of Things, big data, AI, simulation, VR/AR/MR/XR and other technologies, which effectively promotes the further landing of digital twin technology, and then inserts strong wings for product R&D and innovation. In the product design and manufacturing life cycle, the sensor can be installed on the physical prototype, and the data collected by the sensor can be transferred to the digital twin model of the product during the prototype test. By simulating and optimizing the digital twin model, the performance of the final product can be improved and enhanced. You can also use hardware-in-the-loop simulation to verify and optimize product performance by using digital twin models for some parts and physical models for some parts. In the stage of product operation and service, based on the establishment of digital twin data and simulation, the areas that need to be further optimized and improved are analyzed, so as to improve the efficiency and quality of new product research and development.
 
 
「 2. Exploration and practice of intelligent R&D 」

 
In order to shorten the product development cycle, enterprises need to deeply apply simulation technology, establish virtual digital prototype, realize multidisciplinary simulation, and reduce physical tests through simulation; It is necessary to implement the idea of standardization, serialization and modularization to support mass customization or product customization; It is necessary to combine simulation technology with test management to improve the confidence of simulation results. In the era of intelligent manufacturing, a number of software companies have emerged in the industry to actively explore intelligent research and development, and they have landed and practiced in manufacturing enterprises.
 
1) Intelligent R&D tools
 
At present, some intelligent software systems have appeared in product research and development tools, which have become the concrete embodiment of intelligent research and development. For example, Geometric DFM PRO software can automatically judge whether the technological features of 3D models can be manufactured, assembled and disassembled. CAD Doctor software can automatically analyze the problems existing in 3D models. Altair’s topology optimization technology can reduce the weight of the structure on the premise of meeting the functions of the product; System simulation technology can analyze and optimize product performance in the conceptual design stage; PLM has been extended forward to demand management and backward to process management. The Teamcenter Manufacturing system of Siemens has structured the process, which can better realize the reuse of typical processes. Kaimu software is also intelligent based on three-dimensional assembly CAPP, machining CAPP and parametric CAPP.

2) Individualized demand promotes product modular design.
 
Modular design can not only improve design reuse and reduce costs, but also greatly shorten the design and manufacturing cycle of products by reuse. Haier’s intelligent interconnection factory in Shenyang has achieved a high degree of flexibility (supporting the production of more than 500 types of refrigerators) and a high degree of automation (the beat can reach 10s/ set). The factory supports the business model of personalized customization of household appliances, and achieves a good return on investment through the premium on a single product. This is mainly due to the R&D team’s successful modular design of refrigerator products, which combined about 300 parts into 23 modules (including 10 standard modules and 13 variable modules), thus greatly reducing the complexity of digital management of parts, semi-finished products and finished products, and simplifying the manufacturing process and supply chain.
 
3) The concept of digital twins goes deep into product design and operation.
 
Product research and development has changed from traditional product design and analysis certification to virtual prototype (digital prototype) instead of physical prototype, so as to realize full digitalization of design and processing process. By collecting sensor data, the changes of three-dimensional model and physical model are compared to improve product design. PTC cooperated with Merida, a bicycle factory in Taiwan Province, to build a digital twin IoT concept demonstration product. The bicycle data were collected through sensors, and the riding route and habits were analyzed to give danger warnings. In addition, virtual reality monitoring was carried out according to the serial number of the scanned bicycle. Siemens cited digital twins to describe the consistent data model that runs through all links of product life cycle. With the help of this concept, GE, the American general company, installed sensors on the high-temperature resistant alloy turbine blades of the engine, transmitted real-time data according to the required frequency, received by the software platform, stored in data, and then established a digital model. GE also uses digital twinning technology to manage and update the data of real power stations in real time, capture the operation of real power stations and issue warnings.
 
4) Virtual reality technology is integrated into R&D.
 
Virtual reality technology is based on its conception, immersion and real-time interaction, which enables people to interact with the model and produce the same feedback information as in the real world, which greatly improves the efficiency and coordination of design.
 
Canon’s MRERL system realizes the design process of seamless integration of 3D computer rendering model with real-world objects in real environment, and supports multi-user collaborative work and simultaneous complete product design. It is realized by rendering 3D models of existing components and new design concepts, and combining them. For example, by integrating existing car seats into the projection of new car virtual design, users can see the real environment outside the car and the digital virtual model inside the car, including the newly designed dashboard and steering wheel.
 
Cave technology is widely used by automobile enterprises and design companies, and virtual reality technology is used to assist product development. Dassault, one of the leading PLM manufacturers in the world, put forward the concept of 3D Experience, and provided solutions in virtual reality (VR) and augmented reality (AR).
 
5) Simulation-driven innovative design
 
In the conceptual design stage, simulation technology was introduced to optimize the design, which changed the traditional design process. According to the performance requirements of the product and the change of load during the movement, Altair uses topology optimization technology to calculate the transmission path of output, thus constructing the product skeleton, beautifying the appearance on the basis of the skeleton, and continuously optimizing the subsequent design process in the virtual environment. This pre-simulation design method can not only give full play to the imagination and realize innovative design under the condition of ensuring the performance and reliability of the product, but also realize the lightweight of the product, which greatly reduces the product development cycle and cost. The design concept of Altair is adopted in the front wing of Airbus A380, and the weight of the front wing is reduced by 500kg by using topology optimization technology.

6) Combination of topology optimization and 3D printing
 
Topology optimization technology helps designers to obtain the optimal structural shape and design lightweight products under the premise of meeting the requirements of given loads and working conditions. However, the product structure after topology optimization is often asymmetric and irregular, which makes it very difficult to manufacture by traditional methods. Additive manufacturing technology, which is typical of 3D printing, breaks this constraint, and any complex product can be manufactured through 3D printing. The perfect combination of topology optimization technology and 3D printing forms a symbiotic technical framework, which greatly releases the potential of design and enables topology optimization technology to give full play to its innovative value.
 
 
Figure 3 Symbiosis Technology Architecture
 
7) The rise of collaborative design mode.
 
Collaborative design with customers, suppliers and partners based on the Internet to achieve cloud collaboration is also an innovative form of intelligent R&D.. For example, in order to make full use of global development resources and manufacturing resources, Boeing has built a multi-country and multi-organization collaborative design and manufacturing model in different places. Domestic enterprises have gradually begun to try to build innovative product collaborative development teams with foreign R&D institutions through mergers and acquisitions or cooperation, so as to rapidly enhance the company’s product innovation strength.    
 
Generally speaking, it is a complicated and long process to realize intelligent research and development. In addition to establishing a perfect R&D system, enterprises should also realize the automation of data flow in the whole product life cycle through information technology, take users as the center, construct intelligent interconnected products through intelligent R&D, and form a series of product ecological circles, closely link users’ needs, uses and other information with product R&D, and form a closed-loop continuous optimization product R&D and service system.
