当轨道交通信号系统发生故障时极有可能导致列车失去联锁控制,将严重影响到运营的安全。列车失去在ATS信号界面上的显示,对于安全行车造成的隐患更大。对历年来上海轨道交通因信号故障导致的事故进行了分析,提出了信号故障情况下列车失表的应对措施。 When the rail transit signal system failure is most likely to cause the train to lose interlock control, will seriously affect the operational safety. The train lost its display on the ATS signal interface, posing a greater risk to safe driving. The accident caused by signal failure in Shanghai rail transit over the years has been analyzed, and the countermeasures for loss of train in the event of signal failure have been put forward.
