Tramcar operation control method based on 5G-V2X and car-car communication

Abstract

The invention discloses a tramcar operation control method based on 5G-V2X and train-train communication, and relates to the technical field of tramcar signal communication. Under normal conditions, a vehicle-mounted controller is connected to a communication system through a 5G network to communicate with a track side turnout controller, an intersection priority controller and a central dispatching command system; and the vehicle-mounted controller communicates with vehicle-mounted controllers of other trains through a 5G network. When the 5G network is interrupted, the vehicle-mounted controller is directly connected with the track side turnout controller and the intersection priority controller in a communication range in a V2X mode, and sends information to the central dispatching command system in a forwarding mode through the track side turnout controller and the intersection priority controller; and the vehicle-mounted controller directly communicates with the vehicle-mounted controllers of other trains in the communication range in a V2X mode.

Description

Technical field [0001] The present invention relates to a signal rail train communication technologies and, more particularly, to a vehicle-based and 5G-V2X - rail vehicle train control method of communication. Background technique [0002] Modern rail train traffic running as a way to moderate traffic, with efficient, green and so on. Because rail trains are generally on urban roads traveling on the ground, need to go through the turnout area and level crossings, in order to ensure operational efficiency, when passing through these areas, rail train requires timely request by the turnout, level crossing, therefore, in certain areas, the need to ensure that the train rail information exchange with the next tram rail by continuous, stable and reliable vehicle to communicate, in order to achieve a high efficiency by. [0003] Most rail train signal control systems include onboard controller, the controller siding turnout, wayside intersection priority controller, the central dispat...

AI Technical Summary

Problems solved by technology

[0004] 1. The on-board controller sends priority requests for intersections and route processing requests to the trackside through point-to-point communication, which is less flexible and prone to waste of resources. In a few scenarios, errors in route processing or priority opening may occur Happening;

[0005] 2. The reliability of the 4G-LTE network is limited. If the communication network equipment fails, the communication between the vehicle control system and the central dispatching command system may be interrupted;

[0006] 3. The 4G-LTE network speed is relatively slow, the bandwidth is relatively low, and the delay is relatively high, so it is impossible to transmit large files in real time;

[0007] 4. The data interaction between different vehicle controllers depends on the processing and forwarding of the central dispatching command system, and there may be a high communication delay
