ESTIMATED OPERATION CONTROLLER FOR WATER SUPPLY PUMP

摘要

PURPOSE:To secure the smooth operation of a water supply pump by controlling the operation of the water supply pump by utilizing the information after a prescribed time from the control time on the basis of the demand estimation. CONSTITUTION:In a calculation part 8, the quantity of water supply pumps 2a-2n in operation is calculated on the basis of the estimated water supply demand quantity and the discharge quantity of the water supply pump after a prescribed time from the present, and the result of the calculation is outputted into a CRT 12, and if an operator 14 judges that the operation is correct, the operation plan of the water supply pump on the basis of the result is determined, and if the operation is not correct, calculation is carried out again by changing the time after the above-described prescribed time by a keyboard 13, and the optimum operating plan is determined by a program setting part 9. In a judgement part 10, the operation order selecting instruction signal is inputted into an operation order selecting circuit 6 on the basis of the operation plan in the setting part 9 and the water level at present. The circuit 6 inputs a selecting signal into a pump operation circuit 7, and the pump operation in a pump yard 2 is executed. Therefore, the number of times of selecting the pump operation is reduced, and the smooth pump operation can be carried out.
