Abstract

The invention discloses a portable tester for a transponder transmission module.In the static parking conditions of the EMU, a spectrum analyzer, an oscilloscope, an arbitrary signal generator, and anetwork analyzer can be used to test the parameters such as output signal strength and frequency of the transponder transmission module, transponder message receiving function (set the order, strength, time of message transmission according to the standard sequence), interference signal immunity of the transponder transmission module and antenna impedance. In dynamic condition, the parameters of operating underbody environmental disturbance can be tested by the spectrometer and the oscilloscope connected with transponder transmission module antenna cable.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a portable tester for a transponder transmission module. Background technique [0002] The balise transmission module (BTM) is the key on-board equipment of the CTCS-2 / 3 train control system. Its function is to transmit the ground balise message information to the ATP after demodulation and decoding, which is of great significance to the safe operation of the train. [0003] At present, BTM has become the standard equipment of the train control system at home and abroad, especially in recent years, with the rapid development of domestic high-speed railways, it has become more popular. However, there is no portable device that can conduct on-site intelligent analysis and testing of BTM equipment. Contents of the invention [0004] The purpose of the present invention is to provide a portable tester for the transponder transmission module, which can complete the comprehensiv...
