状態監視装置のノイズ除去方法および状態監視装置

摘要

To provide a state monitoring device that suppresses adverse effects on state monitoring due to noise elimination, and can surely eliminate noise.SOLUTION: A data computation unit of a state monitoring device is configured to execute a noise elimination method with respect to measured waveforms, and eliminate impulse noise. The noise elimination method comprises: a step S2 of deciding a reference value Y1 of a noise determination from data on waveforms of a measurement period measured by sensors; a step S3 of including at least the data by one waveform of noise waveforms of the reference value Y1 or more, and deciding a size WS of a processing window of a period shorter than the measurement period; and a step S4 of generating replacement data (effective value RMS2) from a data group in the processing window when the data on the noise waveform exists in the processing window, and replacing the data on the noise waveform with the replacement data.SELECTED DRAWING: Figure 2
