Fault diagnosis system
First Claim
1. A fault diagnosis system for diagnosing faults in complex equipment, the system including:
- means for storing a set of diagnostic signatures which relates a set of known faults which may occur in the equipment to respective fault symptoms which are deemed indicative of said known faults; and
means for processing said diagnostic signatures and a set of fault symptoms identified for a current state of the equipment, to calculate diagnostic data for identifying a fault causing the current state of the equipment, the diagnostic data including a plurality of values which are indicative of different relative non-zero likelihoods of each of a plurality of different known faults causing the current state of the equipment.

Abstract
A fault diagnosis system for diagnosing faults in complex equipment. The system includes means for storing a set of diagnostic signatures which relates a set of known faults which may occur in the equipment to respective fault symptoms which are deemed indicative of said known faults; and means for processing the diagnostic signatures and a set of fault symptoms identified for a current state of the equipment to calculate diagnostic data for identifying a fault causing the current state of the equipment. The diagnostic data includes a plurality of values which are indicative of different relative non-zero likelihoods of each of a plurality of different known faults causing the current state of the equipment.

35. Computer software arranged to implement a fault diagnosis system for diagnosing faults in complex equipment, the computer software implementing:
-
means for storing a set of diagnostic signatures which relates a set of known faults which may occur in the equipment to respective fault symptoms which are deemed indicative of said known faults; and
means for processing said diagnostic signatures and a set of fault symptoms identified for a current state of the equipment, to calculate diagnostic data for identifying a fault causing the current state of the equipment, the diagnostic data including a plurality of values which are indicative of different relative non-zero likelihoods of each of a plurality of different known faults causing the current state of the equipment.

36. A computer-implemented method for diagnosing faults in complex equipment, the method comprising:
-
storing a set of diagnostic signatures which relates a set of known faults which may occur in the equipment to respective fault symptoms which are deemed indicative of said known faults; and
processing said diagnostic signatures and a set of fault symptoms identified for a current state of the equipment, to calculate diagnostic data for identifying a fault causing the current state of the equipment, the diagnostic data including a plurality of values which are indicative of different relative non-zero likelihoods of each of a plurality of different known faults causing the current state of the equipment.
