Equipment motion state detection method, device and system and null drift correction parameter prediction method, device and system

The invention discloses an equipment motion state detection method, device and system and a zero drift correction parameter prediction method, device and system. The method comprises the following steps: firstly, acquiring a current Euler angle in the movement process of an elevator and actual acceleration data acquired at the current Euler angle; secondly, performing feature extraction based on the actual acceleration data to obtain acceleration feature data; thirdly, splicing the acceleration characteristic data with the current Euler angle to obtain acceleration Euler angle spliced data; secondly, zero drift correction parameter prediction is carried out according to the acceleration Euler angle splicing data, and a predicted zero drift correction parameter is obtained; and finally, the motion state of the elevator is detected according to the predicted null drift correction parameter and the actual acceleration data, and the motion state of the elevator is obtained. By splicing the acceleration characteri
