Problems solved by technology

[0003] The eddy current generated by the probe design of ordinary eddy current rail flaw detection can only be used to measure cracks of a certain type of defect, such as transverse cracks, and it is difficult to measure other types of cracks, such as longitudinal cracks
This directly leads to the possibility of missed detection, and the evaluation of quantitative visualization cannot be completed

Abstract

The invention provides a remote rotary eddy current nondestructive inspection detection system comprising at least one detection terminal being used by a user for detecting and a cloud server achieving data interaction with the at least one detection terminal via a wireless communication link; the detection terminal serving as a front-end detection sensor is responsible for damage detection of different users under different scenes and / or occasions, without processing the data, detected original data is transmitted to the cloud server to identify and judge, and thus the cost and use convenience of the local detection terminal are reduced, the data processing equipment does not need to be carried under any scene, the multiple detection terminals can be simultaneously used for performing thedetection at different positions, different factories and different processes, the user does not need to prepare multiple detection system sets, the use cost is reduced, and the efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of eddy current detection, in particular to a remote rotating eddy current nondestructive flaw detection system. Background technique [0002] At present, the methods of rail detection mainly include manual identification, ultrasonic flaw detection, CCD scanning camera and point eddy current flaw detection, but they each have their own advantages and disadvantages. The manual identification method has slow detection speed and poor accuracy, which requires extremely high work quality of the inspectors. Ultrasonic flaw detection is suitable for internal inspection of rails and is easily affected by environmental factors. CCD line scan camera, fast detection accuracy, suitable for rail surface detection, easily affected by impurities on the rail surface. Traditional eddy current flaw detection is suitable for rail surface and subsurface inspection, and can accurately determine the location of defects, but it ...
