Title:
EARLY SIGN DETECTION DEVICE AND EARLY SIGN DETECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/200702
Kind Code:
A1
Abstract:
This early sign detection device comprises: a plurality of sensors; a data acquisition unit for acquiring the time-series change data of a physical quantity from the plurality of sensors; a calculation unit for calculating, from the time-series change data, a parameter indicating the correlation between the physical quantities at two arbitrary positions among a plurality of positions; and a detection unit for detecting an early sign of a suddenly changing oscillation of a detection target on the basis of the parameter indicating the correlation. The plurality of sensors are respectively disposed in a plurality of positions on the detection target, and are configured so as to measure the physical quantity at each position.
