General-purpose adaptive reasoning processor and fault-to-failure progression modeling of a multiplicity of regions of degradation for producing remaining useful life estimations

摘要

The system contains a device and a defining signature of at least one characteristic of the device. The defining signature changing as the device accumulates damage through a period of useful lifetime in a damaged state. A sensor is in communication with the device. The sensor sensing at least one of the characteristics of the defining signature as the device accumulates damage through the period of useful lifetime. A predictive curve is provided with the defining signature mapped over the anticipated useful lifetime of the device in the damaged state. The predictive curve provides a preliminary prediction of the remaining useful lifetime of the device in the damaged state. A reasoner is in communication with the sensor. The reasoner modifies the predictive curve relative to the sensed defining signature, thereby providing a normalization of the defining signature to the predictive curve.
