ABSTRACT:
A method and system for monitoring the activity of a system of one or more electro-mechanical components that receive electrical current from a power supply. The method and system samples an actual current supplied to the electro-mechanical 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 electro-mechanical components is failing, the method and system will shut that component down.
