Abstract
An abnormality detection system includes a waveform acquisition unit configured to acquire waveform data that changes over time; an abnormality degree calculation unit, and an abnormality determination unit. The abnormality degree calculation unit is configured to calculate an abnormality degree based on a cumulative value obtained by accumulating absolute values of differences in data values for each unit time from the waveform data acquired by the waveform acquisition unit. The abnormality determination unit is configured to determine whether the waveform data is normal or abnormal based on the abnormality degree calculated by the abnormality degree calculation unit.
