Method of determining the cause of an error state in an apparatus
First Claim
1. A method of determining the cause of an error state for one or more components within an apparatus comprising a plurality of sensors arranged to monitor the operation of components of the apparatus and a control means arranged to receive information from said plurality of sensors, the method comprising:
- a) during operation of the apparatus, electronically analyzing said sensor information to ascertain sensor patterns from said sensor information;
b) electronically comparing said sensor patterns with detectors comprising an adaptable error prediction system, each detector being a previously defined pattern, indicative of the condition of said one or more components within the apparatus and classifying a matching present state of the apparatus as being a precursor to a fatal state of as not being a precursor to a fatal state;
c) upon detection during operation of the apparatus of a sensor pattern unable to be classified as indicating a precursor to a fatal or nonfatal state, electronically creating an immature detector to classify the sensor pattern, tolerizing the immature detector to evaluate if the detector correctly classifies a condition and discarding the immature detector if it fails to achieve tolerization existing detectors and known healthy states;
d) upon validation of an immature detector, electronically adding the detector to the adaptable error prediction system; and
e) electronically classifying said sensor patterns as being indicative of a precursor to a fatal or nonfatal state based upon a comparison of sensor patterns with said validated detectors comprising the adaptable error prediction system.

Abstract
A method is described for determining the cause of an error state for one or more components within an apparatus. The apparatus comprises a plurality of sensors arranged to monitor the operation of components of the apparatus and a control means arranged to receive said information from said plurality of sensors. The method comprises analysing said sensor information in the form of an error log to ascertain sensor patterns from said sensor information comparing said sensor patterns with detectors, which are predefined patterns, indicative of the condition of said one or more components within the apparatus and classifying said sensor patterns as being indicative of said error state of a component or not based upon a comparison of sensor patterns with said detectors.

13. A machine readable medium storing a program of instructions executable by a computer, the computer operating under the control of the program of instructions to perform a method comprising the steps of:
-
a) during operation of the apparatus, analyzing sensor information to ascertain sensor patterns from said sensor information; b) compare said sensor patterns with detectors comprising an adaptable error prediction system, which are previously defined patterns, indicative of the condition of said one or more components within the apparatus and classifying a matching present state of the apparatus as being a precursor to a fatal state or as not being a precursor to a fatal state; c ) upon detection during operation of the apparatus of a sensor pattern unable to be classified as indicating a precursor to a fatal or nonfatal state, creating an immature detector to classify the sensor pattern, tolerizing the immature detector to evaluate if the detector correctly classifies a condition and discarding the immature detector if it fails to achieve tolerization within a prescribed lifespan, and validating the detector by one or more of evaluation against existing detectors and known healthy states; d) upon validation of an immature detector, adding the detector to the adaptable error prediction system; and e) classifying said sensor patterns as being indicative of a precursor to a fatal or nonfatal state based upon a comparison of sensor patterns with said detectors. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
