Embodiment Construction

[0070] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0071] It should be noted that in this document, relative terms such as "first" and "second" are only used to distinguish the same names, rather than implying the relationship or order between these names.

[0072] In general, in order to break through the traditional CBTC system using the zone controller ZC centralized train operation control theory, the embodiment of the present invention provides a vehicle-to-vehicle communication-based CBTC system to improve and upgrade the traditional CBTC system, and a vehicle-to-vehicle communication-based CBTC system It is a decentralized control model with the core of train autonomous control. Such as image 3 As shown, on ...

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...
