CBTC (communication-based train control) system based on vehicle-vehicle communication

Abstract

The invention discloses a CBTC (communication-based train control) system based on train-train communication. The CBTC system comprises an intelligent train monitoring ITS system, an object controller, a train management platform TMC, a data communication system DCS and an intelligent vehicle-mounted controller IVOC arranged on every train. The CBTC system disclosed in the invention can reduce the ground device and cancel the ground ATP, interlocking and other devices; the IVOC can autonomously calculate the movement license and plan the driving path through information interaction with the IVOC, OC and ITS systems of front and back trains; the ITS system can automatically generate the train running control information based on the site condition to lighten the work load of an operation dispatcher, and promote the operation efficiency and service level, and send to the IVOC; The TMC acquires the limiting-velocity information of the line and sends to every train on the line, thus the safe protection of the train is realized.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a CBTC system based on vehicle-to-vehicle communication. Background technique [0002] The traditional CBTC (Communication Based Train Control, automatic train control based on communication) system is the key system equipment to ensure the safety of train operation, realize traffic command, train operation automation and improve transportation efficiency. The main equipment of CBTC system includes: on-board equipment, trackside Equipment and ground equipment, the specific description of each equipment is as follows: [0003] On-board equipment (Vehicle on board Control, VOBC) includes: on-board automatic protection system (on-board ATP, Automatic Train Protection), on-board automatic driving system (on-board ATO, Automatic TrainOperation), etc.; [0004] Trackside equipment includes: signals, turnouts, transponders, axle counters, automatic parking beacons, platform screen...

AI Technical Summary

Problems solved by technology

At the same time, it also limits the flexible operation control and intelligent level of the train

[0012] 3) There are a lot of ground equipment, which is not conducive to the upgrading and transformation of lines and the interconnection between lines

[0017] 2. The on-board controller VOBC in the existing rail transit fully automatic driving streamlined system can only receive the train operation plan, and then perform movement permit calculation and path planning, and cannot, under special circumstances (such as not receiving the train operation plan), Carry out mobile license calculation and path planning

[0018] 3. The on-board controller VOBC in the existing rail transit fully automatic driving streamlined system can perform speed limit calculations, but when the operating conditions of a certain section of a specific line change, there will be a certain delay in performing speed limit calculations through VOBC , unable to respond quickly, there are security risks
