Title (EN) REMAINING USEFUL LIFE ESTIMATOR
(FR) ESTIMATEUR DE DURÉE DE VIE UTILE RESTANTE
Abstract:
(EN) A method and a system for estimating the remaining useful life, which estimates the life cycle of rotatory equipment in real-time, the method comprising the steps of: receiving high frequency vibration signals; pre-processing the received signals, comprising cleaning the data received from the sensors; extracting features, comprising applying various transformations on the raw data and extracting statistical variables or features, wherein waveforms are processed; selecting features, comprising capturing all relevant information in a minim number of variables; classifying the information, allowing information creation based on technics that automatically classify the data according to the features included, wherein the classification step is used for fault detection, identification of the component involved in the fault and of the fault type, and to estimate the severity of the fault; and estimating the Remaining Useful Life (RUL), wherein a specific model is associated to a specific class, inferring the status of the machinery and estimating RUL by means of non-linear multivariate regression techniques.
(FR) L'invention porte sur un procédé et un système d'estimation de la durée de vie utile restante, qui estiment le cycle de vie d'un équipement rotatif en temps réel, le procédé comprenant les étapes de : réception de signaux de vibration haute fréquence; prétraitement des signaux reçus, y compris nettoyage des données reçues de capteurs; extraction de caractéristiques, y compris application de diverses transformations sur les données brutes et extraction de variables ou de caractéristiques statistiques, des formes d'onde étant traitées; sélection de caractéristiques, y compris capture de toutes les informations pertinentes dans un nombre minime de variables; classification des informations, permettant la création d'informations sur la base de techniques qui classent automatiquement les données en fonction des caractéristiques incluses, l'étape de classification étant utilisée pour la détection de pannes, l'identification du composant impliqué dans la panne et du type de panne, et l'estimation de la gravité de la panne; et estimation de la durée de vie utile restante (RUL), un modèle spécifique étant associé à une classe spécifique, inférant l'état de la machine et estimant la RUL au moyen de techniques de régression multivariée non linéaire.
