Abstract:
Provided in the present invention are a train operation control method and system. The method comprises: determining whether first data which is sent by a vehicle-mounted signal system within a preset number of continuous periods is invalid; and if so, determining that communication abnormality occurs in the vehicle-mounted signal system, and sending an emergency braking command to a train braking control unit by means of a vehicle control unit, wherein communication between the vehicle-mounted signal system and the vehicle control unit is performed on the basis of a real-time train data protocol and by means of a train Ethernet, and the emergency braking command is sent to the vehicle control unit by the vehicle-mounted signal system when the communication abnormality occurs in the vehicle-mounted signal system. The system executes the method. By means of the present invention, the defect of a hard wire interface being used between a vehicle-mounted signal system and a vehicle control unit is solved, and data exchange between the vehicle-mounted signal system and the vehicle control unit is realized on the basis of a real-time train data protocol and by means of a train Ethernet, thereby ensuring that a train control requirement for a train is met when communication abnormality occurs in a data exchange process.
