PUMP CONTROL DEVICE, PUMP CONTROL METHOD AND DRAINAGE SYSTEM
PROBLEM TO BE SOLVED: To provide a pump control device, a pump control method and a drainage system which can follow an elevation of a water level and enhance safety.SOLUTION: A pump control device (12) controls a plurality of pumps which discharge water in a suction sump. Initial values of starting water levels and stopping water levels are set for respective pumps. The pump control device has: a water level determination section (52) which determines whether or not a water level in the suction sump is lowered to the stopping water level of any of the pumps; a starting water level management section (53) which updates the starting water levels in a manner that increases the same; and a pump stop control section (56) which stops the pumps. When any of the pumps does not start after a lapse of a predetermined second period since all the pumps are stopped, the starting water level management section (53) can reset the starting water levels of respective pumps to the initial values.SELECTED DRAWING: Figure 6
【課題】水位の上昇に追従でき、安全性が高いポンプ制御装置およびポンプ制御方法ならびに排水システムを提供する。【解決手段】吸込水槽の水を排水する複数のポンプを制御するポンプ制御装置(12)であって、各ポンプには始動水位および停止水位の初期値が設定されており、前記吸込水槽の水位が、いずれかのポンプの停止水位まで低下したか否かを判定する水位判定部(52)と、始動水位が高くなるよう該始動水位を更新する始動水位管理部(53)と、そのポンプを停止させるポンプ停止制御部(56)とを備え、すべてのポンプが停止した後、所定の第2期間、いずれのポンプも始動しない場合、前記始動水位管理部(53)が各ポンプの始動水位を初期値にリセットすることができる。【選択図】図6
