Remote fault diagnosis and push method and device for robot

The invention discloses a remote fault diagnosis and push method and device for a robot. The method comprises the following steps: acquiring a robot state signal and an operation environment state signal, and pre-processing the robot state signal and the operation environment state signal to obtain pre-processed signals; performing feature extraction on the signals based on time domain analysis and frequency domain analysis to obtain state feature data of the signals; fusing the state feature data of the multiple signals based on a principal component analysis algorithm to obtain operate statefeatures of the robot; substituting the operation state features of the robot into a fault diagnosis model stored in a fault identification model base, performing logic programming to judge that therobot has faults, obtaining a fault type of the robot, and pushing the fault type to a management user terminal to perform real-time display of fault warning. According to the embodiment of the invention, the remote fault diag
