With the increasingly fierce competition in the manufacturing industry, the manual operation and maintenance of traditional motor equipment is inefficient, while its cost is increasingly high. How to solve equipment faults efficiently and cheaply has become an important factor in the development of manufacturing enterprises. Combined with modern information platform, according to the classification of motor faults, fault diagnosis analysis database is established. In combination with expert system, the motor operation and maintenance platform is constructed. It is applied to the enterprise production environment. By equipping the motor equipment with sensors and data acquisition gateway and using the motor operation and maintenance platform system, the operational cost of motor equipment is reduced, the operational efficiency is improved, and the informatization, automation, intelligentization and securitization of manufacturing equipment operation are supported. The operation and maintenance platform can promote the competitiveness of enterprises in the information age.
