METHOD, APPARATUS, AND SYSTEM FOR MONITORING MANUFACTURING EQUIPMENT
First Claim
1. A method for monitoring a manufacturing apparatus, comprising:
- collecting a control signal, of a controller and a corresponding sensing signal, of the manufacturing apparatus over a predetermined period of time;
segmenting the control signal and the corresponding sensing signal to obtain at least one control step;
calculating a character of the controller based on at least one of the control signal, the sensing signal, the at least one control step, or information from a user manual;
generating, based on the character, a health index indicating health of the controller; and
generating a warning signal when the health index exceeds a predetermined threshold.

20. A manufacturing system, comprising:
-
a manufacturing apparatus including a controller; and a monitoring apparatus including; a processor; and a memory storing instructions that, when executed by the processor, cause the processor to; collect a control signal of the controller, and a corresponding sensing signal, over a predetermined period of time; segment the control signal and the corresponding sensing signal to obtain at least one control step; calculate a character of the controller based on at least one of the control signal, the sensing signal, the at least one control step, or information from a user manual; generate, based on the character, a health index indicating health of the controller; and generate a warning signal when the health index exceeds a predetermined threshold. - View Dependent Claims (21)
