Document Type and Number:
WIPO Patent Application WO/2021/079472
Kind Code:
A1
Abstract:
In this anomaly detection method, a computer performs the processes of: acquiring a plurality of pieces of waveform data detected by a plurality of sensors placed on a monitoring target; specifying waveform data on a plurality of targets from the plurality of pieces of waveform data, on the basis of the correlation of the shapes of the acquired plurality of pieces of waveform data; integrating the waveform data on the plurality of targets into one; and dividing, by units of time, the waveform data, which has been integrated into one, to make clusters; and detecting an anomaly in a monitoring target, on the basis of the size of the cluster.
