Remote fault diagnosis and push method and device for robot

Abstract

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 diagnosis and push method can remotely diagnose whether the robot has faults or not, and pushes the faults to corresponding management staff, so that fault diagnosis efficiency of the robot is improved.

Description

technical field [0001] The invention relates to the technical field of remote fault monitoring of robots, in particular to a method and device for remote fault diagnosis and pushing of robots. Background technique [0002] With the continuous increase in the use density of robots, automated, intelligent, and flexible production lines composed of robots are increasingly used in various industrial fields such as welding, spraying, assembly, packaging, handling, and palletizing. The safe, stable, continuous and reliable operation of the robot will bring considerable economic benefits to the enterprise, and once it is shut down for a long time due to failure, it will cause inevitable economic losses to the enterprise. [0003] The extensive use of different brands of robots in various complex production environments has brought great challenges to the daily maintenance of robots. The common failure forms of robots include: mechanical system failure, electrical system failure, s...

Problems solved by technology

[0005] However, these robot remote maintenance systems are generally only for the corresponding robots produced by themselves, and cannot be compatible with robots produced by other manufacturers. In the use of robots, there are often situations where multiple robots from multiple manufacturers are mixed at the same time. remote monitoring of faults, resulting in low maintenance efficiency
