Abstract

The invention provides an online BTM detection method and apparatus. The apparatus comprises a detection host, a display unit, a signal simulator, a spectrum analyzer, a radio frequency power meter, apower supply and a detection vehicle; when overhaul is performed in a bullet train garage, the BTM device does not need to be detached, comprehensive detection is directly performed on a BTM antenna,a cable, a host and other components, and analysis and diagnosis and detection report output can be performed on each detection result; in addition, the online BTM apparatus can establish a historical detection account with the equipment as an object, performs statistic analysis in numerical values, curve charts and other forms for tracking and analyzing the performance change process of each BTMdevice; and the online detection of the BTM device is similar to regular fixed point physical examination, which can effectively help an overhaul unit to find the hidden dangers of the performance ofthe device and take measures in time.

Description

technical field [0001] The invention belongs to the application field of railway signal equipment detection, and in particular relates to an on-line static detection method and a device thereof for the message transmission module equipment of the transponder of the train set in the garage of the train station. Background technique [0002] Transponder message transmission module (abbreviated as BTM), including BTM host and BTM antenna, is mainly used to send the power carrier to activate the transponder to the ground, receive the message sent by the transponder and send it to the train control on-board computer, it is the EMU CTCS2 / 3 An important part of the train control system, the performance and status of BTM equipment directly affect the operation safety of the EMU. Therefore, regular inspection and maintenance of BTM equipment is one of the important tasks of each train control equipment maintenance unit. At present, on-site maintenance of BTM equipment can only carry...
