Design and simulation of digital compensating filter on track irregularity inspection
Jianhui Lin · 2007
The track irregularity is the main factor which affects the train's safety and amenity.Track-geometry-inspecting vehicle can collected data of track irregularity real-time and exactly.However,the change of vehicle's velocity leads to the signal from sensor dying-out and distortion.This makes analysis data incredible.In order to remove the effect of vehicle's speed,this paper analyzed the theory and designing method of digital compensating filter in the vehicle's track inspection system and performed a simulation in the CCS5000.The result indicates that the digital filter can compensate the valuable signal which is weakened previously and the accuracy is rather high.
