Abstract

The invention provides a train rail detection system and method and relates to the technical field of rail detection. An embedded computer device in the system sends sampling pulse signals to an inertia component and a laser photographing component; the laser photographing component shoots steel rail profile images and sends the steel rail profile images to the embedded computer device; the inertia component measures attitude parameters of a detection beam relative to steel rails and sends the attitude parameters to the embedded computer device; the embedded computer device determines transverse displacement data and vertical displacement data of the detection beam relative to the steel rails according to the steel rail profile images; calculation is conducted according to the transverse displacement data, vertical displacement data and the attitude parameters, and unsmooth geometric parameters of the train rails are determined; overrunning judgment is conducted according to the unsmooth geometric parameters, overrunning judgment data are obtained, and waveform data of the unsmooth geometric parameters are generated; and the overrunning judgment data and the waveform data are sentto a ground data processing center device.

Description

technical field [0001] The invention relates to the technical field of track detection, in particular to a train track detection system and method. Background technique [0002] At present, with people's general concern on train safety, the train track detection technology is gradually developing. After years of research and development, the Infrastructure Testing Institute of the China Academy of Railway Sciences has developed four track testing systems, GJ-3, GJ-4, GJ-5 and GJ-6, which have made important contributions to the regulation and daily testing of high-speed railways. contribution. [0003] The existing track detection system takes the GJ-6 type track detection system as an example, such as figure 1 As shown, it is mainly composed of a detection beam 101 installed on the train bogie, a laser and a high-speed camera 102, and a plurality of accelerometers (respectively referred to as the first accelerometer 104, the second accelerometer) arranged in the train bod...
