Abstract

L’invention concerne un procédé de détection (S) d’une défaillance d’un capteur (1), ledit capteur (1) étant configuré pour détecter au moins une vibration d’une pièce d’un moteur, en particulier d’un moteur d’aéronef, et pour fournir une tension électrique représentative de la vibration détectée, le procédé de détection comprenant les étapes suivantes : S1 : mesurer une tension fournie par le capteur (1), S2 : comparer la tension ainsi mesurée à un premier seuil prédéfini, S3 : lorsque la tension est supérieure au premier seuil prédéfini, déterminer au moins un paramètre de forme à partir des mesures de la tension fournie par le capteur (1), S4 : comparer le paramètre de forme ainsi déterminé à un deuxième seuil prédéfini et S5 : générer un signal de défaillance lorsque le paramètre de forme dépasse le deuxième seuil prédéfini. Figure pour l’abrégé : Fig. 3The invention relates to a method for detecting (S) a failure of a sensor (1), said sensor (1) being configured to detect at least one vibration of a part of an engine, in particular of an engine part. aircraft engine, and to supply an electrical voltage representative of the detected vibration, the detection method comprising the following steps: S1: measure a voltage supplied by the sensor (1), S2: compare the voltage thus measured with a first threshold predefined, S3: when the voltage is greater than the first predefined threshold, determine at least one shape parameter from the measurements of the voltage supplied by the sensor (1), S4: compare the shape parameter thus determined with a second predefined threshold and S5: generating a failure signal when the shape parameter exceeds the second predefined threshold.
