A train management method and device based on train-to-vehicle communication

Abstract

Embodiments of the present invention provide a train management method and device based on vehicle-vehicle communication, the method comprising: in the vehicle-vehicle communication driving mode, when the internal communication of the vehicle-vehicle communication train set fails, the vehicle-vehicle communication The train set sends communication failure information to the ground controller, so that the ground controller generates a train activation identification command according to the communication failure information, and sends the train activation identification command to the vehicle-vehicle communication train set; The vehicle-to-vehicle communication train set switches the vehicle-to-vehicle communication driving mode to an automatic driving mode according to the activation flag command. By calculating the movement authorization based on the train position when the vehicle-to-vehicle communication fails, the train position tracking problem that the vehicle-to-vehicle communication is interrupted can be quickly located, and the train activation identification command is sent to the vehicle-to-vehicle communication train set, so that Vehicle-to-vehicle communication trainsets can be quickly switched to automatic control mode.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a train management method and device based on vehicle-to-vehicle communication. Background technique [0002] "Vehicle-vehicle communication" refers to the realization of "vehicle-vehicle" communication through the use of a safe and high-speed communication platform, changing the "vehicle-ground-vehicle" of the traditional communication-based train control (Communication Based Train Control; CBTC) system. structure, shorten the operation interval and improve the operational flexibility. [0003] However, since the vehicle-to-vehicle communication technology is still in the development and promotion stage, in the prior art, the CBTC system vehicle-to-vehicle communication technology has uncertainties in the tracking of track sections. In the existing rail transit CBTC system, in some special cases, such as special road sections such as bridges and tunnels, o...

Problems solved by technology

[0003] However, since the vehicle-to-vehicle communication technology is still in the stage of development and promotion, there are uncertainties in the tracking of track sections by the vehicle-to-vehicle communication technology of the CBTC system in the existing technology

In the existing rail transit CBTC system, in some special cases, such as special road sections such as bridges and tunnels, or in rainy and snowy weather, the network communication quality of the train is not good when it is moving, and it cannot communicate with other trains normally.

If the vehicle-to-vehicle communication is disconnected, at this time, the train will not be able to know which section its own vehicle is in, and cannot track the position of the train, and cannot guarantee the safety of the train.
