The project of “resource centered high availability and simplified architecture train control system technology and application” passed the evaluation of scientific and technological achievements
On November 7, 2020, Shanghai Transportation Trade Association (STTA), jointly entrusted by Thales SEC Transport(TST) and other units, organized a panel composed of five experts in Shanghai to evaluate the project achievements of “resource centered high availability and simplified structure train control system technology and application”. This meeting is attended by representatives from Thales SEC Transport Automation System Co., Ltd., Tongji University, East China Normal University, Shanghai Industrial Control Safety Innovation Technology Co., Ltd. and other units.
The panel listened to the report of the project ” resource centered high availability and simplified structure train control system technology and application”, and reviewed relevant documents. Following evaluation opinions were formed after inquiry and discussion:
- Initially putting forward resource-based train operation control technology. Taking the train as the main body, the application, use and release of line resources are carried out to ensure the consistency of the main body between the applicant and the user, and make safe, efficient and flexible train operation control.
- Innovate high reliability, high availability and flexible design. The central, trackside, vehicle system and network adopt independent dual subsystem hot standby redundancy technology to realize reliable switching between dual redundant systems and support high-quality continuous operation. It solves the problem of reliability bottleneck of interlocking system in traditional CBTC system and the problem of operation quality degradation after being degraded to point backup system.
- Innovate the simplified structure of train control interlocking integration. The safety micro-coding optimization algorithm, real-time synchronization between processes and other technologies are adopted to realize the function of train control interlocking within the safety controller, reduce the interface communication link and delay, improve the overall efficiency of the system, and reduce the construction and maintenance cost of the entire lifecycle.
- The signal system TSTCBTC®0 developed based on the results of the project has been successfully applied to the signal system reconstruction and extension project of Shanghai Metro Line 5. Since the project was put into operation in December 2018, the system has been running safely and stably, and DTO operation has been realized. The delay times and passenger clearance times of five minutes or more caused by signal system failure are zero, which improves the operation service quality, and has significant economic and social benefits.
The Panel agreed that: The project data submitted is complete and detailed, which meets the requirements of achievement evaluation. The findings of the project have reached international advanced levels.
