摘要
为降低基于车车通信的列车自主运行系统(TACS)通信负载,进一步提高系统的可用性,通过分析既有TACS共享轨道区段资源列车之间通信链接的建立机制,提出基于列车追踪器的TACS列车身份管理办法。研究了基于列车追踪器的TACS架构和信息交互机制;在列车处于主模式或非主模式下,分别提出通过轨道区段资源初始化、申请、释放,以及列车筛选等,实现共享轨道区段资源列车身份管理的方法;基于实际线路数据,对既有TACS和基于列车追踪器的TACS进行列车折返性能仿真测试和压力仿真测试。结果表明,基于列车追踪器的TACS车车通信链接数量较少,有效降低了通信负载,也提高了共享轨道区段资源列车故障场景下TACS的系统可用性。
To reduce the communication load of the train autonomous control system(TACS)based on train-train communication,and further improve the availability of the system,a train identity management method of TACS based on train tracker is proposed by analyzing the mechanism of communication links establishing between trains sharing track section resources in the existing TACS.The architecture and communication mechanism of the TACS based on train tracker are studied.For trains under master and non-master modes,a corresponding method is proposed to realize train identity management by the system's initializing,applying for,and releasing track section resources and sieving trains.Based on the actual line data,the existing TACS and the TACS based on train tracker are simulated to test their turn-back performance and operation pressure.The results show that the train-train communication links are fewer in the TACS based on train tracker,which effectively reduces the communication load and improves the availability of the TACS under fault scenarios of trains sharing track section resources.
