Cause-of-anomaly estimation device for fluid machine, cause-of anomaly estimation method therefor, and cause-of-anomaly estimation system for fluid machine

Abstract

In order to obtain a cause-of-anomaly estimation device for a fluid machine that enables simple and convenient, and highly precise estimation of a cause of an anomaly of the fluid machine, the present invention includes: a measurement value input unit to which a measurement value obtained from a sensor installed in the fluid machine is input; a performance calculation unit that calculates the performance of the fluid machine from the measurement value obtained by the measurement value input unit; an anomaly determination unit that determines the presence or absence of an anomaly in the measurement value obtained by the measurement value input unit and in the performance of the fluid machine as calculated by the performance calculation unit; a cause-of-anomaly estimation unit that estimates a cause of an anomaly of the fluid machine on the basis of a determination result regarding the presence or absence of an anomaly in the performance of the fluid machine as determined by the anomaly determination unit, and a cause of an anomaly of the fluid machine pre-stored in a cause-of-anomaly database; and a results output unit that outputs a cause-of-anomaly estimation result regarding the fluid machine as estimated by the cause-of-anomaly estimation unit.
