PROBLEM TO BE SOLVED: To provide a central monitoring device, monitoring system, and monitoring method that enable efficient inspection and repair work, by integrally processing abnormality detection signals from a vacuum type sewage gathering apparatus's vacuum valve unit side and vacuum station side to make it possible to appropriately and quickly provide necessary information for a manager etc.SOLUTION: A central monitoring device 100 can receive a vacuum valve abnormality detection signal for indicating abnormality of a vacuum valve provided correspondingly to each of a plurality of vacuum valve units 200 and a vacuum station abnormality detection signal for indicating abnormality of a vacuum pump 301 or a water collection tank 401. The central monitoring device 100 is configured so that when having received either of a vacuum valve abnormality detection signal and vacuum station abnormality detection signal, the central monitoring device identifies any of a vacuum valve 201, a vacuum valve sensor 202 for detecting the vacuum valve's open/close state, the vacuum pump 301, and the water collection tank 401 as an abnormality occurrence location.SELECTED DRAWING: Figure 1 |
