Abstract

The embodiment of the application provides a method, a system, equipment and a storage medium for processing abnormality of main and standby data of a train, and relates to the technical field of rail transit. The method comprises the steps of obtaining the power-on states of the NVMs of the main system and the standby system of the train, enabling the train to normally operate in a double-system state when the NVMs of the main system and the standby system are in consistent data, enabling the standby system to be down when the NVMs of the main system and the standby system are not in consistent data, enabling the main system not to execute train positioning and to drive according to preset speed limits, and enabling the train to normally operate in a single-system state when the NVMs of the main system and the standby system are independently powered on. The application avoids the occurrence of standby system downtime caused by inconsistent output when the main and standby systems are operated, and ensures the safety in the operation of the train.
