摘要： PURPOSE:To automate a water pumping quantity smoothing operation by re-planing a water pumping plan by itself on the basis of a calculated flow-in quantity and water pumping plan, and a pump well water level and a water pumping quantity both obtained at a real time, and deciding in fuzzy inference whether a re-planed value is used or not. CONSTITUTION:In a pump facility where drainage is discharged to a sewage disposal facility, a flow-in quantity to a pump well is estimated 3 in an autoregressive model on the basis of a water level and a total water pumping quantity detected by a water level gauge 1D and a flowmeter 1E, respectively. The flow-in quantity estimation value is statistically processed 4, and the flow-in quantities for predetermined preceding days are extracted in a pattern. A water pumping quantity plan for given preceding times is calculated 6 based on a total water pumping quantity, flow-in quantity estimation value, and water level, and additionally, A water pumping quantity plan for that day is calculated 7 per preset time unit on the basis of the planed water level and the patterned flow-in pattern. It is decided 11 in fuzzy inference whether or not the plan is renewed to the re-planed plan in a fuzzy inference based on the re-planed water pumping plan flow-in pattern, the flow-in quantity estimation value, and the water level, thus controlling 13 a water pumping pump 1C.

摘要： PURPOSE:To prevent a surplus number of sets from being changed, by obtaining a flow amount of water, which must be drained, from a level regulating water amount of a pump well and its inflow amount so that a number of sets of pumps is controlled. CONSTITUTION:A level regulating water amount is obtained from the water level of a pump well in an arithmetic circuit of a pump. A flow amount of water to be drained is obtained from an inflow amount to the pump well and its level regulating water amount, and a number of sets of the operating pumps is obtained from the flow amount of water to be drained and a pump capacity. The number of sets of the pumps is increased by one set only when the pump well water is placed in an intermediate level or higher, in case of increase of the number of sets, while decreased by one set only when the pump well water is placed in the intermediate level or lower in case of decrease of the number of sets. Consequently, a change of the surplus number of sets of the operating pumps can be prevented.
