Backup mode operation control system and method of train control system

According to the backup mode operation control system and operation control method of the train control system, a centralized traffic control (CTC) system sends route information and route speed limiting information of a front station to train-mounted ATP equipment, after train-ground wireless communication faults occur in the train operation process, the train-mounted ATP equipment is switched to run in a backup mode, and the train-ground wireless communication faults occur in the train operation process; and the vehicle-mounted ATP equipment generates a target speed control curve in the front station according to the route information and route speed limiting information of the front station sent by the CTC system in the dispatching set, and the train runs to the front station according to the target speed control curve in the front station. The train receiving and dispatching efficiency and the in-station running safety of the train control system in the backup mode are improved, and compatibility with an
