摘　　要：双端冗余信号系统中主用车载ATC(列车自动控制)系统和备用车载ATC系统切换时,会中断所有对车辆的输出信号。着重从信号系统冗余切换过程中丢失零速信号、紧急制动信号及牵引制动控车信号后车辆的运行状态及风险进行分析,优化车辆电路实现信号系统无缝切换,保证信号冗余切换的可用性、稳定性,进而提高列车的运营效率及服务质量。When the main on-board ATC controller and standby on-board ATC controller of the dual terminal redundant signaling system are switched,all output signals to vehicles will be interrupted.The analysis of the running state and risk of vehicle after the loss of zero speed signal,emergency braking signal and traction braking control signal in the process of signaling system redundant switching is carried out.Vehicle circuit is optimized to realize signaling system seamless switch-ing,ensuring availability and stability of signal redundancy switching,which further improves train operation efficiency and service quality.
