Abstract: A suction pressure acquisition unit acquires pressure data indicating pressure of a pump. A variation coefficient calculation unit calculates a variation coefficient indicating amplitude of pressure magnitude of the pump on a basis of the pressure data acquired by the suction pressure acquisition unit. An adjustment unit performs adjustment detection information that includes the variation coefficient calculated by the variation coefficient calculation unit, by using a pressure transmission coefficient representing ease of transmission for pressure of the pump. The detection information is used for cavitation occurrence detection. A determination unit 125 detects cavitation occurrence in the pump on a basis of the detection information adjusted by the adjustment unit.
