Title
(EN) FAULT DIAGNOSIS SYSTEM
(FR) SYSTEME DE DIAGNOSTIC DE PANNES
Abstract
(EN)
Described herein is 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 fauts; 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.

L'invention concerne un système de diagnostic de pannes permettant de diagnostiquer des pannes dans un équipement complexe. Le système comprend des moyens de stockage d'un ensemble de signatures de diagnostic mettant en rapport un ensemble de pannes connues susceptibles de survenir dans l'équipement avec des symptômes de panne respectifs réputés indiquer lesdites pannes connues; ainsi que des moyens de traitement des signatures de diagnostic et d'un ensemble de symptômes de pannes identifiés pour un état de courant de l'équipement de manière à calculer des données diagnostics destinées à identifier une panne causant l'état de courant de l'équipement. Des données diagnostics comportent une pluralité de valeurs indiquant différents probabilités relatives non nulles de chaque pluralité de différentes pannes connues causant l'état de courant de l'équipement.
