Title (EN) REAL TIME METHOD FOR PROCESSING ALARMS GENERATED WITHIN A PREDETERMINED SYSTEM
(FR) PROCEDE DE TRAITEMENT EN TEMP REEL D'ALARMES EMISES DANS UN SYSTEME PREDETERMINE
Abstract:
(EN) A method for processing alarms generated within a predetermined system embodies a forward chaining approach to the analysis of alarms. Before an alarm set can be diagnosed, the method includes the steps of: providing a computer database (20) representative of all components of the system capable of faulting and the interconnections between the components; providing rules that relate component faults to generated alarms and to propagation of component faults within the system; determining individual alarm patterns generated by separate faulting of each component of the system; and storing in a computer database (22) individual alarm patterns determined for each component of the system.
(FR) Un procédé de traitement d'alarmes émises dans un système prédéterminé, met en ÷uvre une approche d'enchaînement en avant de l'analyse d'alarmes. Avant de diagnostiquer le déclenchement d'une alarme, le procédé comprend les étapes consistant à produire une base de données informatique (20) représentative de tous les éléments du système exposé aux pannes, et des interconnexions entre les éléments; à produire des règles rapportant les pannes des éléments à des alarmes émises ainsi qu'à la propagation de pannes d'éléments dans le système; à déterminer des configurations d'alarmes individuelles générées par les pannes séparées de chaque élément du système; et à stocker dans une base de données informatique (22) des configurations d'alarmes individuelles déterminées pour chaque élément du système.
