Abstract
(EN)
The present invention relates to an apparatus for predicting equipment damage. The apparatus comprises an input unit, a processing unit,andan output unit. The input unit is configured to provide the processing unit with sensor data for an item of equipment. The processing unit is configured to implement at least one machine learning algorithm. The at least one machine learning algorithm has been trained on the basis of a plurality of calibration sensor data for the item of equipment. Training of the at least one machine learning algorithm comprises processing the plurality of calibration sensor data to determine at least two clusters representative of different equipment states. The processing unit is configured to implement the at least one machine learning algorithm to process the sensor data to assign the sensor data to a cluster of the at least two clusters to determine an equipment state for the item of equipment. The output unit is configured to output the equipment state for the item of equipment.

La présente invention concerne un appareil pour prédire une détérioration d'équipement. L'appareil comprend une unité d'entrée, une unité de traitement et une unité de sortie. L'unité d'entrée est conçue pour fournir à l'unité de traitement des données de capteur pour un élément d'équipement. L'unité de traitement est configurée pour mettre en œuvre au moins un algorithme d'apprentissage automatique. Ledit au moins un algorithme d'apprentissage automatique a été entraîné sur la base d'une pluralité de données de capteur d'étalonnage pour l'élément d'équipement. L'entraînement du ou des algorithmes d'apprentissage automatique comprend le traitement de la pluralité de données de capteur d'étalonnage pour déterminer au moins deux groupes représentatifs d'états d'équipement différents. L'unité de traitement est configurée pour mettre en œuvre le ou les algorithmes d'apprentissage automatique pour traiter les données de capteur pour attribuer les données de capteur à un groupe des au moins deux groupes pour déterminer un état d'équipement pour l'élément d'équipement. L'unité de sortie est configurée pour délivrer l'état d'équipement pour l'élément d'équipement.
