Embodiment Construction

[0049] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0050] In the prior art, the existing robot maintenance system is a maintenance system based on regular maintenance and irregular maintenance schemes, and usually does not have functions such as fault detection, fault diagnosis, and fault prediction at the same time. Actual users of robots are not clear about the quantifiable effect of maintenance on the degree of improvement in equipment. Maintenance behavior as a kind of important information is lost, resulting in the loss of effective information such as failure prediction and diagnosis information. The robot maintenance system does not include predictive maintenance. Fault diagnosis relies on the after-sales service of the ...

Abstract

The invention discloses a fault diagnosis and maintenance method, system and device, and a storage medium. The invention aims to solve the technical problem that targeted maintenance cannot be carried out according to the operation state of a robot in a use process in the prior art. The fault diagnosis and maintenance method comprises the following steps: receiving joint movement data of a robot joint, judging a size relationship between the joint movement data and a fault threshold value, and determining a current life stage of the joint according to the size relationship; inputting the joint motion data into a fault degree model for calculation, and predicting the next life stage of the joint, wherein the life stages comprise a fault-tolerant stage, a degradation stage and a fault stage, and the fault degree model is used for calculating the next predicted life stage of the joint according to the joint movement data; and when the next operation state of the joint is a fault state, sending prompt information to a user to prompt that the joint needs to be maintained.

Description

technical field [0001] The patent of the present invention relates to the field of fault diagnosis of mechanical devices, in particular to a method, system, equipment and storage medium for fault diagnosis and maintenance. Background technique [0002] Industrial robots are multi-joint manipulators or multi-degree-of-freedom machine devices widely used in the industrial field. They have certain automation and can realize various industrial processing and manufacturing functions by relying on their own power sources and control capabilities. Compared with traditional industrial equipment, industrial robots have the characteristics of ease of use, high level of intelligence, high production efficiency and safety, easy management and significant economic benefits, allowing them to operate in high-risk environments. [0003] But at the same time, during the use of industrial robots, continuous maintenance and maintenance are required to ensure the normal operation of industrial ...
