The simulation test system comprises a train control ground simulation subsystem, a train control train-mounted simulation subsystem and a database, wherein the train control ground simulation subsystem comprises an interlocking simulation module, a track circuit simulation module, a train control center and an LEU (Line Side Electronic Unit) simulation module, wherein the interlocking simulation module is used for acquiring admission passage information and interval direction control information; the track circuit simulation module is used for acquiring track circuit occupancy information; the train control center is used for generating carrier-frequency and low-frequency information of a track circuit and data information of a transponder and storing the carrier-frequency and low-frequency information and the data information to the database; the LEU simulation module is used for forwarding the data information of the transponder into the database; the train control train-mounted simulation subsystem comprises a train-mounted simulation module and a train-mounted device, wherein the train-mounted simulation module is used for acquiring the carrier-frequency and low-frequency information of the track circuit, the data information of the transponder and a train running control signal; the train-mounted device is used for displaying and simulating the train running state according to all piece of information; and information exchange of the two subsystems is realized by the database. The train control ground simulation subsystem can also comprise a CTC (Centralized Traffic Control) simulation module and a TSRS (Temporary Speed Restriction Server) which are used for providing a temporary speed restriction command.

Description

technical field [0001] The invention relates to a simulation system and method, in particular to a simulation test system and method based on a CTCS level 2 train control system. Background technique [0002] With the continuous development of China's railways, in order to meet the needs of high-speed and high-density transportation, the China Train Control System (hereinafter referred to as CTCS) has been formulated. CTCS is divided into five application levels according to functional requirements and equipment configuration, namely CTCS level 0 ~ CTCS level 4. [0003] CTCS level 2 is a train operation control system based on track transmission information and adopts a train-ground integrated system design. The CTCS2 train control system includes the CTCS2 train control ground system and the CTCS2 train control vehicle system. Among them, CTCS2 level train control ground system mainly includes transponder, track circuit and train control center (TCC); CTCS2 level train c...

AI Technical Summary

Problems solved by technology

This vehicle-mounted simulation system can only test the vehicle-mounted equipment, but cannot test the compatibility and support between the CTCS2 level train control ground system and the vehicle system, so it cannot accurately evaluate the correctness of the entire CTCS2 level train control system and stability
