PROGNOSTIC AND HEALTH MONITORING BY ENERGY METERING AT POWER SUPPLY INTERFACE

摘要

Provided is an embodiment for a method (300) for performing prognostics and health monitoring. The method includes detecting (304) operational usage data for a line replaceable unit (LRU), and aggregating (306) the operational usage data with previous operational usage data during a period of time. The method also includes determining (308) a total value for the aggregated operational usage data for the period of time, and generating a histogram to track the operational usage data, wherein the histogram comprises a plurality of buckets, each bucket corresponding to a range of values for the operational usage data. The method includes responsive to expiration of the period of time, adding (310) a count to a bucket of the plurality of buckets corresponding to the total value for the aggregated operational data for the period of time. Also provided is an embodiment for a system (100) for performing prognostics and health monitoring.
