Abstract

The invention discloses a motor working condition segmentation method and system, wherein the method comprises the steps: carrying out preliminary segmentation of data in a working condition file according to a rotating speed, and obtaining a plurality of preliminary groups; marking a steady-state current label for current data in each preliminary group; and carrying out secondary segmentation on each preliminary group according to the steady-state current label to obtain a final segmentation result. According to the motor working condition segmentation method, preliminary segmentation is carried out on the sample according to the rotating speed to obtain the preliminary groups, and secondary segmentation is carried out on each preliminary group according to the steady-state current label to obtain the final segmentation result, so that segmentation of the motor working condition can be realized, the effective motor operation working condition can be obtained, the motor state can be monitored, and motor faults are diagnosed.

Description

technical field [0001] The invention relates to the technical field of motor diagnosis, in particular to a method and a system for segmenting motor working conditions. Background technique [0002] Motor state monitoring and fault diagnosis technology is a technology to understand and master the state of the motor during use, determine its overall or partial normal or abnormal, and find faults and their causes. The existing technical solutions are generally state monitoring and diagnostic devices based on electrical characteristic analysis technology. By measuring the current and voltage signals when the motor is running under load, and analyzing the characteristics of frequency spectrum, harmonics, and electrical parameters, it is possible to further detect bearing faults and misalignment. Faults, load faults, mechanical looseness, insulation and a series of electrical and mechanical fault status changes, and then determine the fault of the entire transmission system. [0...
