Abstract:

PROBLEM TO BE SOLVED: To provide an information apparatus provided with mutual interlock control function between information apparatuses by means of which such countermeasures as stopping of the upstream side manhole pump operation in the event of an abnormality are accomplished easily, speedily and surely.
SOLUTION: The information apparatuses 60 (60-1-7) provided for each of the manhole pumps for drainage facilities in which water accumulated in the manhole is pumped up to send to the downstream side manhole pump by connecting plural manhole pumps in series from the upstream side to the downstream side. When any one of the information apparatus (60-1-7) detects that its associated manhole pump has trouble in accumulating the water coming from the upstream side, it sends an interlock control signal through the transmitting means (public lines or private lines) directly to the information apparatus (60-1-7) of the upstream side manhole pump connected thereto stop sending water.
