Abstract

The invention relates to a device and a method for detecting a transponder cable state. The device comprises a signal collection module, a signal processing module and a judgment analysis module. Theinput of the signal collection module is the C interface of an LEU, used for collecting C6 voltage signals and C6 current signals; the output end of the signal collection module is connected with theinput end of the signal processing module; the signal processing module is used for processing the collected C6 voltage signals and C6 current signals, and separately outputting corresponding square signals; the output end of the signal processing module is connected with the input end of the judgment analysis module; and the judgment analysis module is used for analyzing the square signals, and giving a judgment analysis result. Compared with the prior art, the device and method provided by the invention can adaptively detect the cables with different distance lengths, and also can detect thenormal, open circuit and short circuit states of the cables.

Description

technical field [0001] The invention relates to the technical field of cable detection, in particular to a device and method for detecting the state of a transponder cable. Background technique [0002] In the high-speed railway control system, whether the information transmitted by the transponder is correct or not is directly related to the driving safety of the high-speed train. The information transmission between the balise and the train control center mainly depends on LEU (trackside electronic unit), and the balise is connected to the LEU through the balise cable. The train control center cannot receive the transponder information timely and accurately, which affects the control and operation of the train. Therefore, it is necessary to detect the state of the transponder cable in order to troubleshoot early. Due to the complexity of engineering design, the length of the cable varies greatly in the field. However, the traditional cable state detection technology mainl...
