摘要

PROBLEM TO BE SOLVED: To provide a central monitoring device, a monitoring system, and a monitoring method for a vacuum type sewage gathering device capable of appropriately and promptly providing information necessary to administrators or the like, and efficiently performing inspection and repair work.;SOLUTION: A central monitoring device 100 can receive vacuum valve abnormality detection signals indicating abnormalities in vacuum valves 201, 211, 221 provided correspondingly to a plurality of vacuum valve units 200, 210, 220, and vacuum station abnormality detection signals indicating the abnormalities in a vacuum pump 301 or a water collection tank 401. When receiving one of the vacuum valve abnormality detection signals and the vacuum station abnormality detection signals, any one of the vacuum valves 201, 211, 221, vacuum valve sensors 202, 212, 222 detecting an opened/closed state of the vacuum valves, the vacuum pump 301, and the water collection tank 401 is determined as a failure generation part, based on whether or not the other of the vacuum valve abnormality detection signals and the vacuum station abnormality detection signals are received.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2016,JPO&INPIT
