(FR) SYSTÈME D'ENVIRONNEMENT INFORMATIQUE POUR LA SURVEILLANCE DE MOTEURS D'AÉRONEFS
Abstract
(EN)
The invention relates to a computing environment system for monitoring aircraft engines, said system being connected to a cluster of servers, said system comprising: - an application interface (13) configured so as to receive user codes (19) that are developed independently from a distributed deployment system specifying the calculation of a set of indicators relating to an aircraft engine (3) for deployment on a fleet (12) of aircraft engines; - an extraction module (15) configured so as to extract said indicators by deploying parallel calculations on temporal flight data from the fleet of aircraft engines and stored in a database (9) distributed over said cluster (5) of servers (7); - a learning module (17) configured so as to use said indicators to construct, without supervision, from said indicators, a monitoring model (21) representative of the indicators by implementing predetermined learning functions.

L'invention concerne un système d'environnement informatique pour la surveillance de moteurs d'aéronefs, ledit système étant connecté à un cluster de serveurs, ledit système comportant: - une interface applicative (13) configurée pour recevoir des codes (19) utilisateurs développés indépendamment d'un système de déploiement distribué spécifiant le calcul d'un ensemble d'indicateurs relatifs à un moteur d'aéronef (3) pour un déploiement sur une flotte (12) de moteurs d'aéronefs, - un module d'extraction (15) configuré pour extraire lesdits indicateurs en déployant des calculs en parallèle sur des données de vol temporelles issues de la flotte de moteurs d'aéronefs et stockées dans une base de données (9) distribuée sur ledit cluster (5) de serveurs (7), - un module d'apprentissage (17) configuré pour utiliser lesdits indicateurs pour construire de manière non supervisée à partir desdits indicateurs un modèle (21) de surveillance représentatif des indicateurs en mettant en œuvre des fonctions d'apprentissage prédéterminées.
