Rail traffic vehicle-mounted BTM automatic test system and method

Abstract

The invention relates to a rail traffic vehicle-mounted BTM automatic test system and method. The system comprises a simulation driving platform used for simulating electrical buttons on a real bridgeto realize the interaction with a vehicle simulator; the vehicle simulator used for simulating the running speed and location of a vehicle; a computer interlocking used for simulating a trackside device and sending the state of the trackside device to a trackside electronic unit; the trackside electronic unit used for calculating an ID of a transponder message and controlling the opportunity of sending the corresponding ID of the transponder message to a reference signal generator; the reference signal generator used for sending corresponding transponder message information stored in advanceto a reference loop; a BTM used for querying and obtaining the transponder message information stored in the reference loop; and an automatic train protection system used for sending a message query request to the BTM. By adoption of the rail traffic vehicle-mounted BTM automatic test system and method, the message collection action of a vehicle-mounted BTM through a series of transponders on theline can be simulated, which is convenient for the reliability test of the vehicle-mounted BTM.

Description

technical field [0001] The invention relates to the technical field of urban rail transit signals, in particular to a rail transit vehicle-mounted BTM automatic test system and method. Background technique [0002] In actual rail transit operation, the transponder system used in the signaling system is divided into two parts: the ground and the vehicle. The ground part includes the Lineside Electronic Unit (LEU for short), passive transponders and active transponders. The vehicle-mounted part is the Balise Transmission Module (BTM for short), including the BTM host and the BTM antenna. [0003] LEU is a data acquisition and processing unit, which communicates with the interlocking system through a serial or other communication interface, periodically receives the real-time changing message information sent by the interlocking system, and continuously sends messages to the active transponder, The message information includes mobile authorization, temporary speed limit, etc. ...

AI Technical Summary

Problems solved by technology

At present, there are two test environments for the vehicle-mounted BTM system. One is to directly use software to simulate LEU, transponder and BTM, and send messages to ATP directly according to Computer Based Interlocking (CBI) and train position; It is to use real equipment to manually flash the transponder to realize the simulation; both methods have inherent defects, method 1: without the participation of physical equipment, the real running link cannot be simulated; method 2: although there is real equipment, the transponder reports However, the selection of text content and the timing of sending it are difficult to match the actual situation, and it is labor-intensive and difficult to test, and it is impossible to realize automated testing
