Problems solved by technology

[0006]However, at present, the wireless synchronous control communication equipment of locomotives are all independent communication methods, lacking the integration of network communication methods and digital radio communication methods
Although the use of digital radio stations is flexible and does not depend on the ground network, due to the limitation of communication distance, the application effect on the 20,000-ton and longer formation trains with two vehicles still needs to be improved

Abstract

The invention discloses a locomotive double-end wireless synchronous control communication equipment data channel redundancy control method, which can select three communication modes or combinations of an LTE-R, a GSM-R or a data transfer radio according to the actual application environment of a combined train, and realizes reasonable application of network channel resources on the premise of ensuring the service reliability requirement. And meanwhile, a data transmission channel can be rebuilt in time through the data transfer radio under the condition that network data is interrupted, the data transmission channel is provided for the head master control locomotive and the middle slave control locomotive of the combined train, and synchronous traction and synchronous braking of the whole combined train are achieved.

Description

technical field [0001] The invention relates to the technical field of railway wireless communication, in particular to a data channel redundancy control method for dual-terminal wireless synchronous control communication equipment of a locomotive. Background technique [0002] The heavy-duty railway adopts the locomotive wireless reconnection synchronous control system to run 10,000-ton and 20,000-ton combined trains, relying on wireless data transmission to provide data transmission channels for the combined train head master locomotive and the middle slave locomotive to realize combined train synchronous traction, synchronous braking. [0003] my country's railways use GSM-R as a digital wireless communication system. GSM-R data services include CSD (Circuit Switched Data Service) and GPRS (General Packet Data Service). At present, locomotive wireless synchronous control communication equipment adopts CSD mode transmission business data. In the communication mode of circ...
