Abstract

The invention discloses a motor health index evaluation system based on multi-fault feature combination. The system comprises: a data collection module which is used for synchronously obtaining all kinds of operation state data of a motor; a cloud data storage server used for storing various running state data of the motor synchronously acquired by the data acquisition module; a data analysis module used for carrying out signal source analysis to judge various faults according to various running state data of the motor stored in the cloud data storage server; and a health index evaluation module used for adopting a joint diagnosis mode based on an expert system to respectively obtain the fault probability and the fault degree of each type of fault obtained through judgment, and comprehensively scoring each type of fault in combination with the hazard degree of each type of fault to obtain the health state of the motor. By comprehensively evaluating the health state of the motor, the operation and maintenance cost and the maintenance period of the motor are reduced, the economic loss caused by non-planned shutdown is avoided, and the service quality and the service life of key parts are improved.

Description

technical field [0001] The invention relates to the technical field of motor detection, in particular to a motor health index evaluation system based on multi-fault feature combination. Background technique [0002] As the most important driving force and driving device of modern industrial production, the motor is playing an increasingly important role in industrial production. At the same time, the operation, maintenance and repair costs of the motor during use are also increasing. The traditional operation and maintenance The mode has the disadvantages of long maintenance cycle, high time cost and labor cost, unable to achieve planned shutdown, and avoid economic losses caused by unplanned shutdown. In addition, there are also contradictions between over-maintenance and under-maintenance, over-abundance and under-repair of spare parts. Contents of the invention [0003] On the one hand, the present invention provides a motor health index evaluation system based on the ...
