Traction motor anomaly detection method, detection device, detection equipment and storage medium

The invention relates to a traction motor anomaly detection method, a detection device, detection equipment and a storage medium, and belongs to the technical field of traction motor anomaly detection.The traction motor anomaly detection method comprises the following steps: a data acquisition step: screening daily to-be-detected parameters, and filtering main line data to obtain a first data set; a data statistics step: performing statistics on the first data set to obtain statistics, and obtaining a wide table according to the statistics; a dimension reduction step: performing PCA dimension reduction on the data in the wide table; a data processing step: calculating Euclidean distances from all data after dimension reduction to the mass center of the traction motor to obtain a second data set; a data analysis step of performing statistical analysis on the second data set to obtain an alarm threshold value; and a judgment step: judging whether the traction motor is abnormal or not according to the Euclidean
