Research on the application of BDS/GIS/RS technology in the high speed railway infrastructure maintenance

Abstract

The high-speed railway infrastructure maintenance is the key to ensure the safe operation of the railway. The technical characteristics and advantages of Beidou Navigation Satellite System (BDS), Geographic Information System (GIS), and Remote Sensing (RS) are analysed for integrated application based on the practical application of professional engineering infrastructure monitoring, equipment inspection, disaster prevention and warning, workers management and time synchronization, and the solution of intelligent monitoring system for high-speed railway infrastructure maintenance was proposed. And this system supports visual display of vector and electronic map, status query of workers, trains, equipment and infrastructure for remotely monitoring, detecting and managing, which can provide low-cost, reliable and accurate information services for the security monitoring and management of the high-speed railway infrastructure maintenance.

Railway Infrastructures E-Maintenance Systems: A Literature Review

“…Collection information digitally should be considered in railway infrastructure emaintenance to reduce errors if it is carried out manually. Geographical information systems (GIS) are also used in efforts of Turkey and China to digitize maintenance on railway infrastructure [54][55]. GIS utilization can provide geographical perspective in maintaining railway infrastructure thus can allocate the resources wisely [55] & actualize the cost optimization [56].…”

Application and Study of Artificial Intelligence in Railway Signal Interlocking Fault

“…Yang et al analyzed the requirements of clock synchronization of signal ground equipment in combination with the application status of clock synchronization of ground equipment in high-speed railway signal system. By analyzing the advantages and disadvantages of the world's mainstream satellite navigation system and the requirements of China's railway signal system, Beidou time service technology is selected as the clock synchronization technology of the ground equipment of high-speed railway signal system, and the overall scheme based on Beidou time service technology is constructed [6]. In order to evaluate the network access performance of railway signal equipment machine communication (MTC) in the next generation intelligent transportation system, Lin et al divided the railway signal equipment machine communication traffic prediction model into station indoor model, station outdoor model and station outdoor model, and calculated the traffic and signaling overhead of the three models respectively.…”
