AI Technical Summary
Noise interference with acoustic emission technology leads to inaccurate detection of cable fatigue intensity.
By segmenting the cables to be detected, the echo signal of each cable is obtained, and the echo signal is segmented according to the change in the test stress. Select any segment cable as the target segment cable, and select any segment echo signal of the target segment cable as the target echo signal. According to the stability characteristics of the frequency domain amplitude and time domain amplitude of the target echo signal, the frequency domain stability parameters and time domain stability parameters are obtained, and combined with the noise stability parameters, the crack defect segment of the cable to be detected is determined.
The accuracy of cable fatigue strength detection is achieved, by analyzing the noise stability in the echo signal, normal noise interference is eliminated, and crack areas are accurately positioned.
