Abstract

A system for condition monitoring and fault diagnosis includes a data collection function that acquires time histories of selected variables for one or more of the components, a pre-processing function that calculates specified characteristics of the time histories, an analysis function for evaluating the characteristics to produce one or more hypotheses of a condition of the one or more components, and a reasoning function for determining the condition of the one or more components from the one or more hypotheses.

First claim

The invention claimed is:

1. A system for condition monitoring and fault diagnosis of a machine comprising:
a control system operably coupled to the machine having a hierarchical arrangement of controllers, each comprising a processor and a memory, the hierarchical arrangement of controllers configured to implement:
a data collection function that acquires time histories of selected variables for one or more machine components according to specified sampling parameters;
a prepr…
