Title:
ABNORMALITY DETECTION ASSISTANCE DEVICE, ABNORMALITY DETECTION ASSISTANCE SYSTEM, ABNORMALITY DETECTION ASSISTANCE METHOD, ABNORMALITY DETECTION ASSISTANCE PROGRAM, AND COMPUTER-READABLE RECORDING MEDIUM HAVING ABNORMALITY DETECTION ASSISTANCE PROGRAM RECORDED THEREON
Document Type and Number:
WIPO Patent Application WO/2023/062786
Kind Code:
A1
Abstract:
This abnormality detection assistance device comprises: a vibration value acquiring unit 211 for continuously acquiring, with the passage of time t, each of an X-axis vibration value Vx, a Y-axis vibration value Vy, and a Z-axis vibration value Vz representing vibrations in an X-axis direction, a Y-axis direction, and a Z-axis direction which are mutually orthogonal; a three-axis combining unit 212, 212a for generating three-axis composite waveform data on the basis of the X-axis vibration value Vx, the Y-axis vibration value Vy, and the Z-axis vibration value Vz obtained at a plurality of timings; and a frequency analyzing unit 213 for performing frequency analysis by means of a fast Fourier transform on the basis of the three-axis composite waveform data to calculate an analysis value for each frequency component.
