According to reports, China's rail transit operation and maintenance system is expected to achieve a breakthrough. Recently, the project “Organization of Rail Transit Operation and Safety Based on Information Cooperation of Air and Space Vehicles” won the special support of the 2016 National Key R&D Program for advanced rail transit. In the foreseeable future, the integrated monitoring network of air and space vehicles will help ground rail transit to establish a new integrated operational and safety assurance system.

The project was led by Beihang Changying Technology Co., Ltd., and 13 domestic research-related units participated in the joint use of industry, academia and research. The project implementation period was from July 2016 to June 2020. Cao Xianbin, chief scientist of Beihang Changying Technology Co., Ltd. and a professor at Beijing University of Aeronautics and Astronautics, said that this project innovatively tried to adopt the technical idea of ​​“Skynet Monitoring” and introduced advanced equipment systems such as spacecraft and special drones, in an effort to establish A set of rail transit integrated safety monitoring, assessment, forecasting and early warning technology systems achieves controllable objectives on a visual basis.

Efficient operation and safety are the eternal theme of rail transit, but for a long time, the efficient and safe operation of rail transit in China is facing multiple pressures. On the one hand, China's existing rail transit is sparse, dense and heavy, and the proportion of bridges and tunnels along the road network is high. The technical operation of high-efficiency operation and safety guarantee is very difficult. On the other hand, in the future, the promotion of the Belt and Road, the construction of international logistics Under the major strategic background of the channel, China will also develop railway transportation at a high speed, focus on expanding the coverage of the road network in the central and western regions, and promote the development of border areas.

The project of “railway operation and safety comprehensive support technology based on air and vehicle information coordination” supported by the national key R&D plan is trying to improve the large-scale, full coverage and holographic operation of the railway through breakthroughs in new technologies. And comprehensive security support capabilities to change this real dilemma. As the project leader, Cao Xianbin has been engaged in traffic operation monitoring and sky-ground integration network research for many years. He said that with the results of the aerospace industry in recent years, the project will focus on the wide-area wide-area monitoring and multi-scale monitoring information integration of the rail transit system. Such urgent needs, through the establishment of a dedicated network system for the integration of Tianlin air-ground vehicles, effectively integrate the space and ground in the network system, and connect the original distributed sensing and monitoring capabilities into an integrated private network, thus achieving a wide range of rail transit. Stereoscopic information acquisition, trusted transmission and precise management of the status of the domain line, infrastructure, and in-transit train groups, so that it can be seen well, passed well, and judged accurately.
