Title:
MONITORING TARGET DATA STORAGE DEVICE, MONITORING TARGET DATA STORAGE METHOD, AND MONITORING TARGET DATA STORAGE PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/106038
Kind Code:
A1
Abstract:
A monitoring target data storage device 1 comprises: a reception unit 12 that receives monitoring target data from an industrial device 2; a temporary holding unit 14 that temporarily holds a group of monitoring target data received over a predetermined buffer period; an extraction unit 16 that analyzes the group of monitoring target data in the buffer period and extracts data to be stored from the group of monitoring target data; and a storage unit 18 that stores the extracted data to be stored. The extraction unit 16 comprises: a temporal change rate computation unit 161 that computes a temporal change rate of the group of monitoring target data at each time in the buffer period; and a sampling rate changing unit 162 that changes, on the basis of the computed temporal change rate, the sampling rate at which the data to be stored is extracted from the group of monitoring target data.
