Title (EN) STANDARDIZATION OF DATA USED FOR MONITORING AN AIRCRAFT ENGINE
(FR) STANDARDISATION DE DONNÉES UTILISÉES POUR LA SURVEILLANCE D'UN MOTEUR D'AÉRONEF.
Abstract:
(EN) The invention relates to a method and system for standardizing data used for monitoring an aircraft engine (1) comprising: - means (5) for gathering in the course of time temporal measurements on said aircraft engine (1); - means (5) for calculating on the basis of said temporal measurements a set of indicators Ŷ = (Ŷi,..., Ŷi...,Ŷm) specific to elements of said engine; - means (5) for identifying on the basis of said temporal measurements a set of exogenous data X = (*,,...,*„) representative of the exterior context intervening on said set of indicators F; - means (5) for defining a conditional multidimensional model which simultaneously manages the indicators of said set of indicators F while taking account of said set of exogenous data X so as to form a set of estimators Y = (yi,..., y],..., ym) corresponding to said set of indicators Y = (yι,...,yi,...,yn); and – means (5) for normalizing each estimator y} as a function of a reference value of the corresponding indicator y} and of a deviation between said each estimator Ŷi} and said corresponding indicator y} so as to form a set of standardized values F = (~yi,..., ~yJ,...,~ym).
(FR) L'invention concerne un procédé et un système de standardisation de données utilisées pour Ia surveillance d'un moteur (1) d'aéronef comportant : -des moyens (5) pour recueillir au cours du temps des mesures temporelles sur ledit moteur (1) d'aéronef; -des moyens (5) pour calculer à partir desdites mesures temporelles un ensemble d'indicateurs Ŷ = (Ŷi,..., Ŷi...,Ŷm) spécifiques à des éléments dudit moteur; -des moyens (5) pour identifier à partir desdites mesures temporelles un ensemble de données exogènes X = (x1,...,xn) représentatives du contexte extérieur intervenant sur ledit ensemble d'indicateurs F; -des moyens (5) pour définir un modèle multidimensionnel conditionnel gérant simultanément les indicateurs dudit ensemble d'indicateurs F en prenant en compte ledit ensemble de données exogènes X pour former un ensemble d'estimateurs Y = (yi,..., y],..., ym) correspondant audit ensemble d'indicateurs Y = (yι,...,yi,...,yn); et -des moyens (5) pour normaliser chaque estimateur y} en fonction d'une valeur de référence de l'indicateur correspondant y} et d'un écart entre ledit chaque estimateur Ŷi} et ledit indicateur correspondant y} pour former un ensemble de valeurs standardisées F = (~yi,..., ~yJ,...,~ym)
