Abstract

PURPOSE:To enable even an unexperienced person to surely control the operation of pumps by retrieving each control rule stored in a knowledge storage means based on the forecasted value of the water level of a pumpwell to infer the number of pumps to be operated and the pump quantity control timing and controlling the operation of pumps in accordance with inference results. CONSTITUTION:The estimate value of the pumpwell inflow rate is calculated by a pumpwell water level forecasting means 11, and the forecasted value of the pumpwell water level is calculated in accordance with this estimate value, the water level detection signal from a pumpwell water gauge 8, and the outflow rate detection signal from an outflow flowmeter 9. Respective rules stored in a knowledge base 12 are retrieved on the basis of this forecasted value by a pump inference control means 13 to infer the number of pumps to be operated out of pumps 5-1-5-n and the pump quantity control timing, and the operation of pumps 5-1-5-n is controlled in accordance with inference results. Technical knowledge related to pump operation control and control knowledge obtained by experiences of skilled persons can be stored in the knowledge base 12. Thus, even an unexperienced person can surely control the operation of pumps with a high precision.
