Embodiment Construction

[0050]Embodiments of the present application provide a Barkhausen signal feature acquisition method, device, terminal, and storage medium, which are used to solve the existing technical problem of large error in stress testing based on the Barkhausen effect.

[0051] At present, through the Barkhausen effect (Magnet Barkhausen Effect, MBE) produced by the tower material of the transmission tower under the action of the magnetic field, the Barkhausen noise (Magnetic Barkhausen Noise, MBN) released by the ferromagnetic material under the alternating magnetic field is used to measure the noise of the tower material. The stress is large, but Barkhausen noise is a high-frequency noise signal. When using it, it is more reasonable to extract a peak or envelope peak of the MBN signal as the eigenvalue for calculation, but its waveform has obvious randomness. , the wave crest fluctuates greatly, which leads to the technical problem of large error in the existing stress test based on the...

Abstract

A Barkhausen signal feature acquisition method, device, terminal and storage medium. In this application, the high-frequency noise signal is divided into multiple signal segments by using the zero point of the low-frequency sinusoidal signal, and the peaks caused by the randomness of the noise signal are smoothed by superimposing adjacent signal segments and superimposing and averaging the signal peaks Vigorous fluctuations, thereby improving the accuracy of feature value extraction, thereby improving the accuracy of stress testing, and solving the existing technical problem of large errors in stress testing based on the Barkhausen effect.

Description

technical field [0001] The present application relates to the technical field of signal processing, and in particular to a Barkhausen signal feature acquisition method, device, terminal and storage medium. Background technique [0002] Transmission line is an important infrastructure for power transmission, and its safety is related to the stable operation of the entire power grid. Among them, the safety of the transmission tower is an extremely important part of the transmission line. Therefore, it is necessary to carry out stress detection on the transmission tower from time to time to prevent the collapse accident caused by the excessive load of the transmission tower. [0003] At present, through the Barkhausen effect (Magnet Barkhausen Effect, MBE) produced by the tower material of the transmission tower under the action of the magnetic field, the Barkhausen noise (Magnetic Barkhausen Noise, MBN) released by the ferromagnetic material under the alternating magnetic fiel...
