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, me

Example Embodiment

[0045] The present invention will be further described below in conjunction with the accompanying drawings:

[0046] like figure 1 shown, figure 1 A schematic structural diagram of the rail transit vehicle-mounted BTM automated test system of the present invention is shown. In this embodiment, the rail transit vehicle-mounted BTM automated test system includes:

[0047] The simulated driving platform 1 is used to simulate the electrical buttons on the real driving platform. The simulated driving platform 1 drives the electrical equipment through the hardware connection, and can also collect the current status of the electrical buttons, such as the relevant data of traction and braking values. , through the traction handle, direction handle, key, indicator light and driver man-machine interface DMI, to realize the interaction with the vehicle simulator;

[0048] The buttons include mode upgrade, mode downgrade, confirmation, automatic return, open left door, close left door, ...

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. ...
