Correlating Power Signatures with Automated Equipment

摘要

A system for monitoring an activity of a tape drive system having one or more electro-mechanical components, said electro-mechanical components receiving electrical current from a power supply. The system comprises a mechanism for sampling an actual current supplied to said electro-mechanical component from said power supply during said activity; a mechanism for reading a theoretical current for said activity; a mechanism for calculating a statistical value for said actual current and said theoretical current; a mechanism for comparing said statistical value to at least one threshold value; and a mechanism for outputting information to at least one of a user, another system, and another process based on said comparison of said statistical value to said at least one threshold value.
