Patent Abstract / Summary

Die Erfindung betrifft ein Verfahren zur Bestimmung und/oder Überwachung des Zustandes eines elektromechanisch betriebenen Schmierstoffspenders,wobei der Schmierstoffspender einen mit Schmierstoff gefüllten Behälter und eine austauschbar an den Behälter angeschlossene, elektromechanische Antriebseinheit aufweist, mit welcher Schmierstoff aus dem Behälter zu einem Auslass förderbar ist,wobei die Antriebseinheit oder ein oder mehrere in die Antriebseinheit und/oder in den Behälter integrierte Sensoren Messdaten für eine oder mehrere Messgrößen zur Verfügung stellen undwobei auf Basis der Messdaten zumindest ein Zustand des Schmierstoffspenders bestimmt wird.Das Verfahren ist dadurch gekennzeichnet,dass die Messdaten oder daraus erzeugte Daten als Eingabedaten von einem mit Methoden des maschinellen Lernens trainierten Klassifizierungsalgorithmus verarbeitet werden, welcher auf Basis der Eingabedaten einen Zustand des Schmierstoffspenders klassifiziert. Dazu können die Messdaten z.B. mit einer vorgegebenen Abtastrate als Zeitreihen mit jeweils einer Vielzahl von Messwerten für eine oder mehrere Messgrößen zur Verfügung gestellt werden und diese Zeitreihen oder daraus erzeugte Daten als Eingabedaten (E) von dem Algorithmus verarbeitet werden.
