Document Type and Number:
WIPO Patent Application WO/2021/080116
Kind Code:
A1
Abstract:
A predictive maintenance device and a predictive maintenance method for an automated guided vehicle are disclosed. According to the disclosure: operation-related data, measured by a sensor, about an automated guided vehicle is received; the operation of the automated guided vehicle is recognized from the operation-related data and is then divided into a plurality of first functional factors; by learning details about failure occurrences in the automated guided vehicle according to the status change of each of the plurality of first functional factors, a plurality of first failure patterns corresponding respectively to the plurality of first functional factors are generated; a second functional factor influencing a failure occurrence in the automated guided vehicle is extracted from the plurality of first functional factors on the basis of a prescribed criterion; and the point of a failure occurrence in the automated guided vehicle can be predicted on the basis of a second failure pattern corresponding to the second functional factor among the plurality of first failure patterns.
