Title:
METHOD AND SYSTEM FOR DETERMINING ABNORMALITY IN INDUSTRIAL MACHINE
Document Type and Number:
WIPO Patent Application WO/2022/091575
Kind Code:
A1
Abstract:
A first process involves acquiring drive system data indicating a dynamic state of a drive system. A second process involves performing a frequency analysis on the drive system data so as to acquire analysis data indicating a power spectrum of the drive system data. A third process involves determining the Gaussian distribution of the analysis data and acquiring a feature amount indicating the Gaussian distribution. A fourth process involves assessing whether the drive system is abnormal on the basis of the feature amount.
