APPLIANCE MANAGEMENT SYSTEM, APPLIANCE MANAGEMENT DEVICE, AND APPLIANCE MANAGEMENT METHOD

摘要

An EMS (30) is equipped with a control unit (31) for obtaining a first measurement value which indicates an operating state of an apparatus (11) at a predetermined time point and at least one second measurement value which indicates an operating state of the apparatus (11) at a time point earlier than the predetermined time point. The control unit (31) calculates a first reference value, which indicates a reference for the operating state of the apparatus (11), by using the second measurement value and determines the presence/absence of an anomaly of the apparatus (11) on the basis of a comparison result between the first measurement value and the first reference value.
