Research on Backup System of Train Operation Control System Based on Vehicle to Vehicle Communication

[目的]目前,以TACS(列车自主运行系统)为代表的基于车-车通信列车运行控制系统后备系统尚不完善,需对其后备系统进行进一步地深入探讨和研究。[方法]分析了新的运营需求,结合新技术的发展,对一种基于环境识别的TACS后备系统进行探讨。详细介绍了TACS后备系统的架构及功能,分析了TACS后备系统建设的技术难点,阐述了TACS后备系统的列车运行空间监测场景及降级运行场景应用情况。[结果及结论]在发生故障后列车降级运行的情况下,TACS后备系统能提高运营TACS系统效率,并能增强运营安全性。

[Objective]At present,represented by TACS(train autonomous control system)and based on vehicle to vehicle communication,the backup system of train operation control system is not perfect,and needs to be further discussed and studied.[Method]By analyzing new operational requirements and combined with the development of new technologies,a TACS backup system based on environment identification is discussed.The architecture and function of TACS and its backup system are introduced in detail,and technical difficulties in building the TACS backup system are analyzed.The application of the above system in train operation space monitoring and degraded operation scenarios is expounded.[Result&Conclusion]In case of train failure and degraded operation,the TACS backup system can improve operation efficiency and enhance operation safety.
