城市轨道交通车-车通信系统融合设计

Integrated design of a vehicle-to-vehicle communication system for urban rail transit

文章以青岛地铁6号线工程为例,通过对基于车-车通信的TACS系统展开研究,对列车控制系统方案进行简化统一,优化调整系统架构及功能分配,形成列车自主运行系统实施方案。该系统保持以列车为核心,基于车-车通信实现列车主动进路与自主防护功能;在系统降级情况下,由OC实现非通信列车追踪、行车资源回收以及进路安全防护等系统降级功能,这种功能分配可提高系统可用性,方案合理可行。

This paper takes the Qingdao metro line 6 project as an example.Through the study of the Train Autonomous Circumambulation System(TACS)based on vehicle-tovehicle communication,the train control system plan has been simplified and unified,the system architecture and function allocation have been optimized and adjusted,and an implementation plan of the TACS has been formed.The system keeps the train as the core,realizing the active train entry and autonomous protection functions based on vehicleto-vehicle communication.In the case of system degradation,the Object Controller(OC)realizes system degradation functions such as non-communication train tracking,vehicle resource recovery and road safety protection.The optimization of this function allocation improves the system availability,and the plan is reasonable and feasible.
