Non-destructive testing methods are used to monitor the rails in operation to ensure the safety of train operation. Compared with traditional manual testing methods, non-destructive testing technology has higher detection efficiency and detection accuracy, and can also reduce the manual operation cost of railway detection. Based on the above advantages, this article combines two modules of linear structured light and pulsed eddy current array. Linear structured light can detect rail surface defects, pulsed eddy current array can detect defects inside and deep within the rail, defect information can be obtained through image processing, and the location of the defect can be accurately located by GPS locator, thereby improving the efficiency and Accuracy, and to ensure the safety of the rail. Railway transportation enables railway maintenance personnel to find and replace damaged rails in time.
