Abstract

The invention provides a method for monitoring a manufacturing device, comprising: collecting a control signal of a controller and a sensing signal corresponding to the manufacturing device within a predetermined period of time. The control signal and the corresponding sensing signal are divided to obtain at least one control step. A characteristic of the controller is calculated according to at least one of a control signal, a sensing signal, at least one control step, or information obtained from a user manual. A health indicator of the controller is generated according to the characteristic. When the health indicator exceeds a predetermined threshold, a warning signal is generated.

Description

technical field [0001] The present invention relates to a method, device, system and non-temporary computer-readable storage medium for monitoring a manufacturing device. Background technique [0002] Equipment failure can cause serious problems in manufacturing, in the optoelectronic and semiconductor industries. Considering market value and global competition, companies hope to avoid production lag caused by equipment failure. [0003] Successful companies typically mitigate the risk of equipment failure by actively investing in equipment maintenance and management to ensure high levels of productivity. This involves monitoring equipment and condition assessment down to the component level. Based on the results of this monitoring and evaluation, the company can make real-time decisions on machine maintenance to avoid equipment failure during production. [0004] In the optoelectronic and semiconductor industries, manufacturing devices include, for example: chemical vapo...
