INTELLIGENT CONDITION MONITORING AND FAULT DIAGNOSTIC SYSTEM FOR PREVENTATIVE MAINTENANCE

摘要

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.

1. A continuous health monitoring system comprising:
a data collection function that acquires time histories of one or more component energy dissipation values during component operations; a pre-processing function that computes metrics using an operational energy dissipation from the time histories and a baseline energy dissipation; an analysis function for evaluating whether the computed metrics exceed predetermined threshold values 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, wherein the data collection, pre-processing, and analysis functions operate in parallel with the component operations.
