Method and system for simulating trackside device of interconnected crossover line

Abstract

The embodiment of the present invention discloses a method and system for simulating a trackside device of an interconnected crossover line. Information interaction is performed between a host trackside simulator of a host line and a target trackside simulator of a target line. In a process that a train crosses from the host line to the target line, before the head of the train crosses a demarcation point, the host trackside simulator transmits the first message information of a target transponder from the target trackside simulator to an onboard controller, in order that the onboard controller can determine, based on the first message information, the line information whether the target line currently allows the train to enter before the train crosses the demarcation point. The onboard controller controls the train to cross the demarcation point and enter the target line to ensure safe driving only when the first message information allows the train to enter the target line. The method, by means of the information interaction between the trackside simulators of different lines, can obtain the condition of the line to be entered in advance during a train crossing process, and ensures the driving safety of the train.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of train over-the-line operation control, and in particular, relate to a simulation method and system for interconnected over-the-line trackside equipment. Background technique [0002] In the indoor test platform, the trackside simulator is mainly responsible for simulating the driving and mining display of real line trackside equipment (such as axle counting section, signal machine, turnout, screen door, emergency stop button, etc.), and completes the interlocking required Equipment relay status acquisition and interlock command response. At the same time, the trackside simulator also completes the simulated transmission of the balise message information, and completes the reception of the balise message by the on-board equipment. In a common CBTC line, the trackside simulator mainly completes the trackside device driving and transponder message sending of the line, and there is ...

AI Technical Summary

Problems solved by technology

[0008] The present invention aims to solve the problem that in the process of the existing simulated train crossing the line, the train cannot obtain the line status of the target line before the train crosses the line from the own line and completely enters the target line, and cannot guarantee the safety of the train entering the target line from the own line

[0009] On the other hand, before the train completely enters the target line, the trackside simulator of the target line cannot know the occupancy information of the axle counting section in the line crossing area, and the lag of the axle counting section occupancy information is updated as the driving seat belt hidden problems
