Abstract

The invention provides a dynamic magnetic detecting probe and an electromagnetic array method. The dynamic magnetic detection probe comprises a dynamic magnetic detecting module, a main controller module and a communication module. The main controller module is electrically connected to the dynamic magnetic detecting module. The communication module is in communication with the main controller module, and the main controller module transmits the collected data to the communication module. The dynamic magnetic detection probe can detect defects with small scales and high precision.

Description

technical field [0001] The invention relates to the technical field of electronic information, in particular to a dynamic magnetic detection probe and an electromagnetic array control method. Background technique [0002] The industrialization and practical application of oil and gas pipeline defect detection technology and equipment is of great significance. [0003] Magnetic flux leakage detection is an internal detection technology for pipeline defects that has been formed at home and abroad. The magnetic flux leakage detection technology is based on the constant magnetic field provided by the permanent magnet to magnetize the detection area of ​​the pipe wall. The magnetic field leakage signal generated by the pipe wall defect is measured by the Hall sensor and other magnetic field sensing elements, and the pipeline defect information is identified according to the characteristics of the magnetic flux leakage signal. [0004] Magnetic flux leakage testing can generally ...
