Train temporary speed limitation management method based on train-train communication

Abstract

The embodiment of the invention provides a train temporary speed limitation management method based on train-train communication. The train temporary speed limitation management method comprises the steps that if a train management center TMC receives upgraded temporary speed limitation information sent by an intelligent train monitoring device ITS, according to train information obtained in advance and sent by an object controller OC, the updated temporary speed limitation information is sent to an intelligent train-mounted controller IVOC arranged on a traveling train to enable the IVOC to update temporary speed limitation; and if the TMC does not receive upgraded temporary speed limitation returned by the IVOC within a preset period, the TMC sends temporary speed limitation failure information to the ITS to manage temporary speed limitation. According to the train temporary speed limitation management method based on train-train communication, the information communication traffic between the TMC and the IVOC can be increased, the communication efficiency is improved, and temporary speed limitation management for the rail traffic train is optimized accordingly.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of rail transit, in particular to a train-vehicle communication-based temporary speed limit management method. Background technique [0002] With the development of rail transit technology, for different train running states, it is necessary to temporarily limit the speed of the train, which brings new challenges to the management of the temporary speed limit of the train. [0003] figure 1 It is a traditional CBTC system architecture diagram. The system is mainly composed of several important subsystems such as the on-board controller subsystem (VOBC), the zone controller subsystem (ZC), the interlock subsystem (CI), the ATS subsystem, and the DSU subsystem. composition. The database storage unit (DSU) is the key equipment on the ground in the CBTC system. It not only stores static data such as the only electronic map of the entire line, system configuration data, protocol config...

This process greatly increases the communication pressure of the DCS backbone network. At the same time, if there is interference during the communication process, it will cause false alarms and cause system shocks.
