Abstract

The invention relates to a method and device for the predictive maintenance of devices, a system and a medium. The method for the predictive maintenance of the devices comprises the steps of obtainingat least one physical measured value set representing the working conditions of a device, wherein the at least one physical measured value set respectively comprises a plurality of physical measuredvalues which are acquired in a predetermined time period and represent the corresponding working conditions; calculating a device capability index on the basis of the at least one physical measured value set, wherein the device capability index indicates whether the device needs maintenance or not; and determining whether the device needs maintenance or not on the basis of the device capability index.

Description

technical field [0001] The present disclosure relates to data analysis, and in particular to methods, systems, devices and media for predictive maintenance of equipment. Background technique [0002] The automobile production process includes four parts: stamping, welding, painting and final assembly. With the continuous advancement of the automation process of the production process, car factories have introduced a large number of welding torches controlled by robot arms, such as pneumatic servo spot welding torches, to perform welding and processing on various parts of the car body. [0003] The abnormal operation of the welding torch may lead to poor quality of solder joints, which will affect the quality of the car body, increase the repair rate, and more seriously may cause production stoppage. In order to ensure the normal work of the welding torch, the maintenance of the welding torch has become an important part of the work in the workshop. [0004] At present, for...
