The Signal Processing in Track Irregularity Detection

Abstract:

In order to overcome the non-uniform property of time domain signal which is obtained in the process of track irregularity detection, design a set of equidistant signal sampling system to collect signal. Use the EMD method based on the criterion of continuous mean square error de-nosing. By integrating the signal get the space trajectory of vector. Experiments show that the track irregularities detection accuracy has been greatly improved.
