一起ATP停车故障引起车-地联合分析的处理及建议

在列车运行过程中,如果出现瞬间掉码、接收到有源全零应答器报文等异常信息,必然导致动车组停车或减速运行。由于该类故障是瞬间发生,而且涉及列控系统的地面设备与车载设备的结合部,所以需要不断积累相关数据,加强盯控分析,才能最终找出故障原因。本文通过一起动车组STM解码延时的实际案例,提出解决问题的相关建议。

Treatment and Suggestion of Joint Train-ground Analysis Caused by ATP Stop Failure

During the operation of an EMU train,the train will stop or decelerate if instantaneous code missing or receiving all-zero message from an active transponder occurs to the onboard equipment.Because such a fault occurs instantaneously and involves the juncture of the ground equipment and the on-board equipment of train control system,it is indispensable to keep all-theway watch on train operation and to accumulate relevant data for analysis in order to find out the cause of the fault finally.Through one actual failure case of STM decoding delay,some suggestions to solve the problem put forward.
