Abstract

The invention discloses a transponder simulation system and a test system in rail traffic. The simulation system comprises a bridge simulation module, a vehicle dynamics module, a lineside simulation module, an interlocking simulation module and a lineside electronic unit (LEU) simulation module; the bridge simulation module is used for simulating an actual bridge; the vehicle dynamics module is used for obtaining a speed and a position of a simulation vehicle according to status data acquired by the bridge simulation module and actual parameters of a train; the LEU simulation module is used for establishing communication connection between the interlocking simulation module and the lineside simulation module; the lineside simulation module is used for simulating lineside elements and sending a transponder message according to the speed and the position of the simulation vehicle and the position of a transponder in a line; and the interlocking simulation module is used for driving simulation lineside elements according to state information of the simulation lineside elements. The test system comprises the simulation system and a tester. According to the transponder simulation system and the test system, sending time of messages of the transponder can be really simulated, and reliable detection of the transponder is facilitated.

Description

technical field [0001] The invention relates to a transponder testing system and method, in particular to a transponder testing system and method in rail transit. Background technique [0002] In real rail transit, a transponder is a point-type device used to transmit information from the ground to the train. Its main purpose is to provide reliable fixed and variable information on the ground to the on-board operation control equipment. These information usually include The basic parameters of the line, the speed limit of the line, special positioning, temporary speed limit, obstacles, etc. Since the transponder plays a key role in the running of the train, how to conveniently and reliably simulate the transmission of the transponder has become a problem that must be solved in the testing process. [0003] Currently on the market, there are usually two ways to test the transponder message, one is to use the real environment for testing, that is, to use the real train to run...
