Detection Method for Hydraulic Support Cylinder Leakage Based On Sound Enhancement Technology
A detection method of hydraulic support cylinder leakage based on sound enhancement technology is proposed.By collecting and processing the leaked sound signal,high-precision leakage identification and location are realized by using wavelet transform,blind source separation,adaptive gain control and other technologies.The experimental results show that this method is excellent in improving signal-to-noise ratio,detection accuracy and positioning accuracy,and can effectively ensure the safe operation of coal mine hydraulic support.
