Abstract

L'invention concerne un procédé et un système d'analyse de données d'essais relatives à un composant moteur, comportant : - un dispositif d'acquisition (3) configuré pour acquérir un signal temporel multivarié (15) de données d'essais relatives audit composant moteur (9), - un dispositif de traitement (5) configuré pour identifier des motifs (21) dans ledit signal temporel multivarié et pour associer des étiquettes auxdits motifs transformant ainsi le signal temporel multivarié en une séquence (19) d'étiquettes, et - un dispositif de stockage (7) configuré pour stocker ladite séquence (19) d'étiquettes formant ainsi une base de données (17) indexée permettant l'exploitation de données d'essais.The invention relates to a method and a system for analyzing test data relating to an engine component, comprising: - an acquisition device (3) configured to acquire a multivariate time signal (15) of relative test data said motor component (9), - a processing device (5) configured to identify patterns (21) in said multivariate time signal and to associate labels with said patterns thus transforming the multivariate time signal into a sequence (19) of labels , and - a storage device (7) configured to store said sequence (19) of labels thus forming an indexed database (17) allowing the use of test data.
