Title:
UNIDIRECTIONAL BROADCAST-BASED TRAIN CONTROL DATA TRANSMISSION METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/196565
Kind Code:
A1
Abstract:
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.
