Abstract

This abnormality monitoring device is equipped with: an acceleration data acquisition unit for acquiring measurement data about the acceleration of a vehicle chassis; an abnormality presence determination unit for determining whether an abnormality is present on the basis of a comparison between the acceleration and a threshold; a frequency analysis unit for analyzing the acceleration frequency when the abnormality presence determination unit determines that an abnormality is present, and an abnormality type identification unit for identifying abnormality type on the basis of the frequency pattern.
