For high-speed maglev operation control system, train location is a safety-critical function. Whether these functions can be realized has a vital impact on the safe operation of the maglev train. This paper first analyzes the interface relationship between the operation control system and the vehicle location system, and then establishes safety processing modeling for the operation control system by means of the state diagram. In order to control the complexity, the safety processing model is divided into two levels, namely the location system state machine and the location channel state machine. Through the safety processing, the non-safe location information generated by the vehicle location system is processed as safety location information, such as position, speed and driving direction of a certain train.
