CBTC (Communications Based Train Control) signal system simulation testing platform

Abstract

The invention provides a CBTC (Communications Based Train Control) signal system simulation testing platform, which comprises a signal bus, a simulation vehicle-mounted and simulation vehicle system, a simulation station, a simulation rail side system, a three-dimensional vision system and a testing platform management system, wherein the simulation vehicle-mounted and simulation vehicle system, the simulation station, the simulation rail side system, the three-dimensional vision system and the testing platform management system are mutually connected through the signal bus. By applying the invention, an integral solution including vehicle, scheduling and signal systems can be checked and demonstrated; a signal system can be subjected to function and performance tests indoors, and failure injection conditions which can not be simulated in various sites can be carried out indoors, thus testing means are enriched and safety of the system is improved; and simulation checking under the condition of multiple vehicles can be passed, a method for analyzing the railway operation capability is deeply researched, and the reference is provided for the layout of signal devices.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a CBTC signal system simulation test platform. Background technique [0002] The existing communication-based train control (CBTC, Communication Based Train Control) system includes multiple subsystems, and each subsystem needs to adopt many new technologies. It is unrealistic to conduct field tests for all subsystems. To verify the functions and ensure the integrity of the functions after system integration, it is generally necessary to build a simulation test platform for the CBTC system and test the signal equipment that is about to go online through the simulation test environment. Safety and reliability are of great importance. [0003] In the field of simulation testing of train control systems, there are several simulation testing systems widely used in the industry, such as the VISION system developed by the British AEA Railway Technology Company, the RAILSIM system...

AI Technical Summary

Problems solved by technology

[0005] 1. None of the simulation test systems in the prior art is a simulation test system for the CBTC system;

[0006] 2. A small number of simulation test systems for urban rail transit control systems only simulate a part of the entire CBTC system, failing to establish a complete set of simulation test systems for the simulation, testing and verification of the CBTC system as a whole;

[0007] 3. The simulation test systems in the prior art are all simulation test systems for a specific purpose, which cannot be flexibly configured according to needs, and have poor reusability and versatility
