Asynchronous motor bearing fault intelligent detection method and device

The invention provides an asynchronous motor bearing fault intelligent detection method and device, and relates to the technical field of fault intelligent detection, and the method comprises the steps: receiving a control instruction of an asynchronous motor; controlling the asynchronous motor to obtain N bearing monitoring data streams; extracting an nth bearing monitoring data stream corresponding to the nth bearing; performing health deviation analysis on the nth bearing to obtain a health deviation matrix of the nth bearing; performing fault detection on the nth bearing to obtain a fault detection result of the nth bearing; and obtaining an auxiliary component monitoring data set of the asynchronous motor, performing fault correlation compensation on the nth bearing fault detection result, and generating an nth bearing fault detection report. According to the invention, the technical problems of high singleness and low accuracy of bearing fault detection of the asynchronous motor in the prior art can be
