The Joint Laboratory of rail transit sensing and transmission was inaugurated

on October 18, the unveiling ceremony of the Joint Laboratory of rail transit sensing and transmission of Shanghai Institute of microsystems and information technology, Chinese Academy of Sciences and China Railway Communication and signaling Corporation was held at Shanghai Institute of microsystems. Jiangmianheng, vice president of the Chinese Academy of Sciences, and zhangshuguang, deputy chief engineer of the Ministry of railways, unveiled the joint laboratory. Qi Ming, Secretary of the Party committee of Shanghai microsystem Institute, and Miao Weizhong, deputy general manager of China Railway Communication and signaling Corporation, signed a joint laboratory cooperation agreement on behalf of the two sides

Jiang mianheng emphasized in his speech that information technology and informatization are the important characteristics of the times in today's world. Information has become an important means of production in today's society, and information network has also become an important production tool. The establishment of the rail transit sensing and transmission joint laboratory is an important combination of scientific and technological innovation of the Chinese Academy of Sciences and the development of the national rail transit industry, and a specific measure to promote scientific and technological innovation

The unveiling ceremony was presided over by Academician Wang Xi, director of Shanghai microsystem Institute. More than 120 leaders and representatives from the Ministry of railways, the Shanghai Municipal Development and Reform Commission, the science and Technology Commission, Jiading District, Zhabei District, the basic bureau of the Chinese Academy of Sciences, the high technology bureau, the planning and Finance Bureau, the Shanghai Branch, and the Shanghai microsystem Institute, as well as some members of the academic committee attended the unveiling ceremony

the construction and development of rail transit, especially high-speed railway, has provided a low-carbon, environmentally friendly, safe, reliable, fast and efficient transportation guarantee for global economic development. High speed railway has become a booster for the development of human society. At present, China has become the country with the fastest development of high-speed rail, the most complete system technology, the strongest integration capacity, the longest operating mileage, the fastest operation speed and the largest scale under construction in the world. China's economy is ushering in the era of high-speed rail. China's success has also led to an international upsurge of high-speed rail construction

with the continuous expansion of the coverage of rail transit network, the continuous improvement of operation speed and the continuous improvement of the requirements of economic and social development for rail transit transportation quality, how to further ensure and improve the operation efficiency, transportation safety and service quality has become an urgent problem to be solved at present. Wansheng has also made suggestions and progress in packaging methods, product design, etc., and the sensing and transmission technology is rail transit safety The basic information technology necessary for reliable operation is an advanced means to maintain and optimize the capacity of transportation tools in the whole life cycle, and it is also an important support to comprehensively improve the service quality of rail transit industry. China has long-term research and accumulation in sensing and transmission technology. The application of advanced technology in this field to high-speed rail is conducive to maintaining China's long-term international leadership in high-speed rail technology

recently, Shanghai microsystem Institute and China Railway Communication and signaling Corporation have actively cooperated in the field of rail transit sensing and transmission, completed the vehicle ground wireless transmission test with a speed of 350 kilometers per hour, and achieved good results. With the support of the Ministry of science and technology, the Ministry of railways, the Chinese Academy of Sciences and the Shanghai municipal government, the two sides decided to build a joint rail transit sensing and transmission laboratory, make continuous efforts and innovation, and create a world-class rail transit sensing and transmission technology research base

according to Miao Weizhong, deputy general manager of China Railway Communication and signaling Corporation, the laboratory was established by Shanghai microsystem Institute and China Railway Communication and signaling Corporation, and the initial construction cost was about 50million. Facing the major national and industrial needs, the laboratory will integrate China's rail transit sensing and transmission research forces, give full play to the advantages of talents and disciplines, focus on rail transit sensing and transmission technology research, build a system integration and engineering application transformation platform, and build a core force and R & D base for national rail transit sensing and transmission technology research with complete system, capable capacity, advanced platform, and close integration of industry, University, research and application, Become a world-class research institution in this field. The development prospect of rail transit market and the development status of rail transit sensing and transmission technology determine that China's rail transit sensing and transmission technology has a broad platform for display and play, and it is also the basic starting point for us to establish a professional joint laboratory. Zhang Shuguang said

the academic committee is composed of domestic industry academic authorities such as Wang Liding, Wang Keming, Wang Xi, Fang Jiaxiong, Wu Jiangxing, Li Shutang, zoushichang, academician Xiong Youlun and so on. Wang Xi said that the laboratory will focus on the research of rail transit sensing and transmission technology and build a system integration and engineering application platform

in order to ensure the safe and comfortable operation of rail transit, it is necessary to study special sensing technology to sense the real-time state of the train (speed, position, lateral acceleration and stress) and maintain the key monitoring of key components. In addition, the vehicle ground wireless transmission of high-speed rail needs to overcome the problems of high-speed movement, frequent switching, banded coverage and electromagnetic interference, and build a high-capacity and highly reliable transmission channel, which will be an important research direction of the laboratory. Model and classify the dynamic data generated by the train and its operating environment, establish a system integration and engineering application platform, provide status display, in transit warning, real-time operation and maintenance for the rail transit system, and ensure the safety and comfort of driving

Jiang mianheng pointed out that the Chinese Academy of Sciences should make full use of the broad stage for the development of its processing technology provided by the era background of China's industrialization, urbanization and information construction, further play the role of locomotive in building an innovative country, and closely integrate with the locomotive of the Ministry of Railways, China's plastic machinery enterprise market will be opened up, so as to jointly lead and drive China's modernization forward, Make new and greater contributions to improving the country's ability of independent scientific and technological innovation, maintaining the international leading position of China's high-speed rail technology, and meeting the growing social needs of the people to test standards and norms
