The invention discloses a Beidou time synchronization method and system for a rail transit train operation control system. The method comprises the following steps: performing overall time service on a train operation control ground subsystem according to a Beidou time signal; performing synchronous time service on a train operation control vehicle-mounted subsystem according to the Beidou time signal; and transmitting train time to the train operation control ground subsystem by the train operation control vehicle-mounted subsystem, and checking and adjusting station equipment time based on the train time by the train operation control ground subsystem. By adopting the technical scheme, the problem of time synchronization of a moving train and a ground station in the running process of a rail transit train is solved.

    本发明公开一种轨道交通列车运行控制系统北斗时间同步方法和系统,包括:根据北斗时间信号对列车运行控制地面子系统进行总体授时;根据所述北斗时间信号对列车运行控制车载子系统进行同步授时;列车运行控制车载子系统将列车时间传递给列车运行控制地面子系统,列车运行控制地面子系统基于所述列车时间进行车站设备时间的校核与调整。采用本发明的技术方案,解决轨道交通列车运行过程中移动列车与地面车站时间同步的问题。
