High-speed train operating environment monitoring vehicle ground information verification method, device and system

Abstract

The invention provides a high-speed train operation environment monitoring train-ground information verifying method, device and system. The method includes the steps of receiving a first original ground operation environment basic message sent by a first train-ground transmission node, broadcasting the first original ground operation environment basic message firstly, receiving a second original ground operation environment basic message sent by a second train-ground transmission node in the forwarding direction of a train after the first broadcast message is received, judging whether the first original ground operation environment basic message and the second original ground operation environment basic message are coincident or not, if yes, sending the first original ground operation environment basic message to an alarm display terminal of the train, and if not, continuing to receive a third original ground operation environment basic message sent by a third train-ground transmission node in the forwarding direction of the train for consistency judgment. The high-speed train operation environment monitoring train-ground information verifying method, device and system can realize the accuracy of train-ground transmitted messages, so that the train-ground transmitted messages are more accurate, and the running safety of the train is guaranteed.

Description

technical field [0001] The invention relates to the technical field of vehicle-ground communication, in particular to a method, device and system for checking vehicle-ground information of high-speed train operating environment monitoring. Background technique [0002] With the rapid development of communication technology, especially radio technology, people began to study the high-speed train operating environment monitoring vehicle-ground information verification system based on communication technology. The high-speed train operating environment monitoring vehicle-ground information verification system uses wireless communication to reliably and Transmit vehicle-ground two-way information. [0003] The high-speed train operating environment monitoring vehicle ground information verification system based on wireless sensor network is a modern information system that realizes timely collection of ground information and timely transmission of data to trains, and provides fr...

AI Technical Summary

Problems solved by technology

[0005] The existing high-speed train operating environment monitoring vehicle-ground information verification system does not verify the correctness of the train-ground transmission information. In the event of an emergency, information transmission without verification will lead to serious consequences and affect Train emergency braking decision-making, which in turn affects the driving safety of high-speed trains
