吸水井の水位計測に基づき所定の起動水位で運転開始され、所定の停止水位で運転停止されるポンプと、警報発信手段とを備えているポンプ場の監視システムであって、
ポンプの運転時間を計測し積算する手段と、吸水井への流入量を検出する手段と、ポンプの運転時間が増大傾向にあるときの流入量の増減傾向から運転時間長さが正常であるか否かを判定する手段とを具備しており、
運転時間長さが正常でないと判定されたとき、上記警報発信手段を動作させるように構成していることを特徴とするポンプ場の監視システム。A pump station monitoring system comprising a pump that starts operation at a predetermined start water level based on water level measurement of a water absorption well, and stops operation at a predetermined stop water level, and an alarm transmission means, Whether the operating time length is normal from the means for measuring and integrating the pump operating time, the means for detecting the inflow to the well, and the increasing / decreasing tendency of the inflow when the pump operating time is increasing Means for determining whether or not, A pump station monitoring system characterized in that, when it is determined that the operation time length is not normal, the alarm transmission means is operated. 上記吸水井への流入量の検出手段が、吸水井の水位が停止水位から起動水位に上昇するまでの時間長さとそれら両水位間の吸水井容量により平均流入量を演算し検出する手段である請求項１に記載のポンプ場の監視システム。 The means for detecting the amount of inflow into the water well is a means for calculating and detecting the average amount of inflow based on the length of time until the water level of the water well rises from the stop water level to the starting water level and the capacity of the water well between these water levels. The pumping station monitoring system according to claim 1.
