Title:
STATE MONITORING SYSTEM, STATE MONITORING METHOD, STATE MONITORING PROGRAM, AND RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2018/139505
Kind Code:
A1
Abstract:
Provided are a state monitoring system, a state monitoring method, a state monitoring program and a recording medium which are easy to introduce. This state monitoring system (1) is provided with an acquiring unit (11) and a generating unit (12). The acquiring unit (11) acquires from a measuring device (2) which measures an electrical signal, which is an output from or an input into a converting device (4), waveform data representing the waveform of the electrical signal. The generating unit (12) uses the waveform data to generate analysis data for monitoring a state related to the converting device (4). The generating unit (12) obtains, by frequency analysis, a plurality of combinations of a frequency value and a feature quantity value comprising an intensity or a phase, from the waveform data when a driving frequency value is varied. The generating unit (12) is configured to generate the analysis data including at least three variables, namely the frequency, the feature quantity and the driving frequency.
