Abstract: To analyze the safety function of train locating in high-speed maglev train operation control system, the interface relationship between high-speed maglev train operation control system and vehicle locating system is briefly analyzed. Safety model of train locating in the operation control system is described based on fault tree method. According to the safety model and the main safety protection procedures involved, principle and realization process of core functions such as verification of train driving direction, train speed information checking, train reference position and relative position information checking, as well as train insert-run are expounded.
