Hydraulic support anomaly detection method and device, electronic equipment and storage medium

The invention provides a hydraulic support anomaly detection method and device, electronic equipment and a storage medium. The method comprises the steps that initial sound data are collected through a sound mobile collection device; offsetting the initial sound data to generate a plurality of covariance matrixes; determining a target acquisition direction; and adjusting to the target acquisition direction, acquiring target sound data, and processing the target sound data to determine whether the target sound data is abnormal or not. Whether the hydraulic support is abnormal or not is determined by arranging the movable sound mobile collection device to collect the sound data of the hydraulic support, and compared with a mode of collecting the data of the hydraulic support through a fixed underground sensor in the prior art, the influence of an underground complex environment on the collected data can be reduced; and meanwhile, by calibrating and changing the sound collection direction of the sound mobile col
