Correlating power signatures with automated equipment

摘要

A method and system for monitoring the activity of a system of one or more electromechanical components that receive electrical current from a power supply. The method and system samples an actual current supplied to the electromechanical component from the power supply. Next, the method and system reads a theoretical current for the activity of the system. A statistical value is computed from comparing the actual current and the theoretical current. This statistical value is compared to upper and lower threshold values. Depending upon this comparison, the system issues various output messages. Further, if this comparison indicates that one of the electromechanical components is failing, the method and system will shut that component down.
