A unidirectional broadcast-based train control data transmission method, comprising: a station data server obtains train control data, compiles the train control data into a first wireless message, and sends the first wireless message to a ground safety broadcast system;the ground safety broadcast system obtains the first wireless message sent from the station data server and transcodes the first wireless message into a second wireless message;and the ground safety broadcast system sends the second wireless message to a train safety communication system by means of unidirectional broadcast. Also disclosed is a unidirectional broadcast-based train control data transmission system. Unidirectional communication is used in the train control data transmission system, so that the data transmission process is optimized, the timeliness and accuracy of train control data transmission are improved, and operation costs and construction difficulty are greatly reduced.

A method for controlling multiple trains on the basis of vehicle-to-vehicle communication, comprising: S1, determining a train departure/arrival state;if the train is controlled to depart, entering S2;if the train is controlled to arrive, entering S3;S2, multiple trains travelling by using a marshalling mode, a dispatching device compiling a departure plan, and a group control device controlling the trains to travel according to the plan;and S3, multiple trains entering the station by using a marshalling mode, the dispatching device compiling a vehicle arrival plan, and the group control device controlling the trains to stop at the station according to the plan. The mode of independent train control is broken, and multiple trains are controlled as a group according to a one-train control mode. By using the multi-train control mode, and by means of train group planning, vehicle-to-vehicle communication, and a vehicle-to-ground communication mode, multi-train control is implemented, a train tracking interval is shortened to the greatest extend, and departure time is shortened, thus trains use high speeds, the density of train departure/arrival at a station is improved, the line transportation capabilities are excavated to the greatest extend, and the line transportation efficiency is improved. Also provided is system for controlling multiple trains on the basis of vehicle-to-vehicle communication.
