Problems solved by technology

[0009] It can be seen that the ground equipment of the above-mentioned CTCS3 train control system has a complex system structure due to its large number of components, and the complex interface relationship increases the difficulty and cost of system development, operation and maintenance, and introduces some safety hazards ( If the train control center collects the code of the faulty track circuit, it will still give the train a green light in dangerous situations)

Embodiment Construction

[0041] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0042] Such as figure 2 The ground equipment of the high-speed railway train control system shown mainly includes dispatching centralized control subsystem (CTC), trackside zone control subsystem (WZC), wireless communication center RC and trackside target control unit; among them:

[0043] The dispatching centralized control subsystem communicates with several trackside area control subsystems through the CTC data communication Ethernet;

[0044] Each wayside area control subsystem communicates with several wayside target control units through the field bus;

[0045] The wireless communication center adopts a safe communication protocol to realize continuous and two-way safe communication between the trackside area control subsystem and the trains under jurisdiction.

[0046]Similar to the traditional dispatching...

Abstract

The invention provides ground equipment of a high-speed railway train control system. The ground equipment comprises a CTC (Centralized Traffic Control Sub System), WZCs (Wayside Zone Control Sub Systems), an RC (Radio Communication Center) and wayside target control units, wherein the CTC is communicated with a plurality of WZCs through CTC data communication Ethernet; each WZC is communicated with a plurality of wayside target control units through field buses; and the RC realizes continuous two-way secure communication between the WZCs and trains governed in a governing zone through secure communication protocols. The ground equipment has the advantages that the hierarchicalization and the distribution of intelligent maintenance decisions are realized, and fast maintenance and decision making can be performed by aiming at adverse data.

Description

technical field [0001] The invention relates to the technical field of railway transportation control, in particular to ground equipment of a high-speed railway train control system. Background technique [0002] As the core of modern railways to ensure driving safety and improve transportation efficiency, the train operation control system is an automated system for commanding, controlling and managing trains by integrating advanced control technology, communication technology, computer technology and railway signal technology , [0003] At present, my country's CTCS (Chinese Train Control System, China Train Operation Control System)-level 3 train control system (such as figure 1 shown) is mainly composed of the ground subsystem and the on-board subsystem, among which: the ground subsystem mainly includes the train control center (TCC), station interlocking, dispatching centralized control system (CTC), radio block center (RBC), temporary speed limit Server, ZPW-2000 tra...
