An intelligent detection system for magnetic flux leakage based on the Internet of Things

Abstract

The invention provides a magnetic flux leakage intelligent detection system based on the Internet of Things, including a mobile device, a detection device, an analysis device and a controller. The detection device is arranged on the mobile device, and the detection operation is performed on the detection device. In order to slide at the detection position; the analysis device is configured to plan the movement path of the detection position, and collect and analyze the detection data based on the detection rules; the controller controls the connection with the mobile device and the analysis device respectively. By using the reference plane to guide the detection position of the detection device, the controller drives the moving path of the mobile device, and detects the path of the magnetic sensor according to the reference plane, so that the detection accuracy is accurate. At the same time, by being used in conjunction with the moving device, the detection device can follow the guidance of the reference plane to ensure that the detection device can move in a parallel, arc or circular path.

technical field [0001] The invention relates to the technical field of intelligent detection, in particular to a magnetic flux leakage intelligent detection system based on the Internet of Things. Background technique [0002] In the process of magnetic detection, there is a great uncertainty, and more and more accurate detection accuracy and detection validity in the magnetic flux leakage detection process and requirements are paid more and more attention. [0003] For example, the prior art CN107514544A discloses a pipeline magnetic flux leakage detection system. Factors such as mechanical vibration caused by a non-smooth detection surface will reduce the detection sensitivity, resulting in large errors in the detection results.

Another typical prior art such as WO02033398A1 discloses a magnetic induction device sensor for magnetic flux leakage detection. Today, the magnetic flux leakage detection sensor device for storage tanks can only receive and convert magnetic flux leakage signals in two directions, but cannot dissipate to The leakage magnetic field in the air is converged and collected, and there is a certain error, resulting in low accuracy and sensitivity of the sensor

It often leads to inaccurate flaw detection and untimely detection of defects. In order to avoid safety accidents, let’s look at a magnetic detector disclosed in the prior art such as JPH07294491A. At this stage, the general magnetic flux leakage detection device is due to detection The accuracy is not enough, the subtle defects of the tested ferromagnetic materials cannot be accurately detected, and the actual safety hazards of the equipment cannot be effectively obtained in advance, which leads to passive related processing in the later stage, and even leads to large-scale accidents

[0004] In order to solve the common problems in the field such as poor detection accuracy, large detection error, low sensitivity and inability to know tiny defects, the present invention is made
