ABSTRACT

The rapid development of rail transit puts forward higher requirements for rail inspection. In this paper, a kind of eddy current sensor is used to design a track flaw detector which can realize high-speed detection. The two eddy current sensors are placed one after the other at a fixed interval. When the train is running at a constant speed, the sensors perform detection in sequence. The two sensors measure the signal at a fixed point at a fixed time interval. When both sensors measure a crack signal at a certain point, the detector will give an alarm and determine its location to improve the reliability of detection.
