The embodiment of the invention provides a train main and standby system data exception processing method, system and device and a storage medium, and relates to the technical field of rail transit. The method comprises the steps that the NVRAM power-on states of a main system and a standby system of a train are obtained: if the NVRAMs of the main system and the standby system are powered on at the same time, when the NVRAM data of the main system and the standby system are consistent, the train is made to operate normally in a double-system state; when the NVRAM data of the main system and the NVRAM data of the standby system are inconsistent, the standby system is downtime, and the main system does not execute train positioning and runs according to the preset speed limit; and if the NVRAM of the main system is independently powered on, data comparison of the NVRAM of the main system and the NVRAM of the standby system is not executed, and the train is made to normally operate in a single-system state. By means of the method and device, the situation that the standby system crashes due to inconsistent output when the main system and the standby system operate is avoided, and the safety in the train operation process is guaranteed.

    本申请实施例提供一种列车主备系数据异常处理方法、系统、设备和存储介质,涉及轨道交通技术领域。方法包括获取列车主系与备系的NVRAM上电状态:若为主系与备系的NVRAM同时上电,当主系、备系的NVRAM数据一致时,令列车以双系状态正常运行;当主系、备系的NVRAM数据不一致时,令备系宕机,主系不执行列车定位并按预设限速行驶;若为主系的NVRAM单独上电,则不执行主系、备系的NVRAM数据比对,并令列车以单系状态正常运行。通过本申请,避免了主备系运行时因为输出不一致导致备系宕机的情形发生,保证了列车运行中的安全性。
