Diagnostic method and system for valve electric actuator and computer readable storage medium

The invention discloses a diagnosis method and system for a valve electric actuator and a computer readable storage medium. The diagnosis method for the valve electric actuator can comprise the following steps that S1, switch type information of a to-be-diagnosed electric actuator is obtained; s2, collecting real-time operation data of the electric actuator; the real-time operation data comprises a plurality of operation parameters; s3, outputting a diagnosis result according to the switch type information and the plurality of operation parameters; wherein the step S3 comprises the steps of S31, selecting a preset and corresponding diagnosis model according to the switch type information; s32, inputting the plurality of operation parameters into the corresponding diagnosis models to obtain comparison information; and S33, according to the comparison information, judging a fault type, and outputting a diagnosis result. According to the diagnosis method, a plurality of operation parameters with feature points o
