Abstract
A distributed equipment abnormality detection system is provided for monitoring physical amounts of equipments of identical type and detecting an abnormality of each equipment. The distributed equipment abnormality detection system includes equipment management apparatuses that manage the equipments; and a management server apparatus for communicating the equipment management apparatuses. Each equipment management apparatus includes a communication unit that communicates with the management server apparatus; a measurement unit that repeatedly measures the physical amount of the equipment; a distribution information generation unit that calculates distribution information from the measured physical amount; a distribution comparison unit that calculates a difference between the distribution information generated by the distribution information generation unit, and integrated distribution information on the entire equipments delivered from the management server apparatus; and an abnormality determination unit that determines whether or not the equipment is abnormal based on the calculated difference.
