基于无线通信的列车控制系统下后备模式的选择与应用

后备模式是城市轨道交通信号系统在设备故障时降级运行、保持一定运营秩序的一种手段,是保证故障列车安全退出运营的一种设备技术保障。介绍了基于无线通信的列车控制系统下不同制式的后备模式的构成、特点,阐述了后备模式的作用,并从系统设计和标准适用的角度,提出了选用后备模式的关键条件及应用效果。

Application and Selection of Fallback Mode in CBTC System

Fallback mode of CBTC system is used in the degraded operation in case of any device fault in urban transit signaling, it can keep certain operation ability and assure the failed train to exit operation safely.With an introduction of the structure and characteristics of different types of fallback mode in CBTC system,the functions of fallback mode are elaborated, the key conditions and application effects related to fallback mode selection from the perspective of system design and standard applicability are proposed.
