US 6,756,907 B2 · Maintainance support system for an electrical apparatus

Abstract

The present invention describes a maintenance support system that can be used to automatically isolate defective components in a complex electrical apparatus. The system includes programming instructions that activate individual components of the electrical operation in a non-operational sequence, while collecting performance data for each tested component. Performance data is provided by existing feedback devices in the apparatus as well as by additional sensors which are a part of the new system. All collected data and available background information are analyzed by programming instructions that consider, among other things, the probability of failure in certain components. The final outcome is a component replacement recommendation on a local or remote computer display that combines the performance data, history, probability and operational knowledge of the apparatus, thereby improving the performance of service personnel.

Dependent claims

A maintenance support system for an electrical apparatus, comprising:

power switching means connected between a source of electrical power and one or more electrical loads;
computer means connected to said power switching means;
reporting means connected to said computer means;
sensing means connected to said computer means and responsible to said electrical loads;
said computer means further comprising program means which causes said power switching means to selectively energize and de-energize said electrical loads creating different responses in said sensor means, said program means having been designed to analyze said responses and indicate defective components of said apparatus through said reporting means.
