Abstract

The present invention proposes a train communication transmission method and system. The train head communication component is configured with a first transmission module, a second transmission module, an information conversion module and a first control module; the train communication component is configured with a third transmission module and a second transmission module. Four transmission modules; the third transmission module sends train internal information to the first transmission module, the fourth transmission module sends the same train internal information to the second transmission module, and the information conversion module transmits information to the first transmission module and the second transmission module After unpacking, comparing, and deleting duplicate information, the information is transmitted to the first control module. When the train transmits information to external communication targets, the information is segmented and hierarchically transmitted, and a unique identifier is set for each segment of information. The train communication transmission method and system provided by the present invention solve the problem of unstable internal communication of the train through the multi-transmission network inside the train, and enable orderly transmission of a large amount of information in the train by grading and sorting information on the external network.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a train communication transmission method and system. Background technique [0002] Modern trains are developing towards high speed, automation and comfort. Compared with traditional trains, more and more information (such as status, control, fault diagnosis, passenger service, etc.) is generated, and there is an urgent need for mutual transmission and exchange between computers on train vehicles. How to safely, quickly, reliably and accurately transmit these large amounts of information on the entire train and to the ground control system has become a key issue in the development of the train communication transmission system. [0003] The communication components on the train include the head communication components installed at the front of the train, the in-vehicle communication components in several compartments, and the rear communication components in the rear com...
