    • PROBLEM TO BE SOLVED: To provide a control method of well device, and well device which decreases fine particle of earth and sand that flows in by reducing start and stop frequency of submerged pump as much as possible, and which suppresses total water supply cost to minimum.
      SOLUTION: The control system decides before beginning of water supply of submerged pump by simulation water supply start time, water supply expected completion time, and the amount of scheduled water supply of each time and time zone by which total supply cost becomes the lowest, based on the measurement signal of water gauge and predetermined demand pattern; and after beginning of water supply of the submerged pump, the control system calculates the amount of target water supply for every setting time interval at any time based on the measurement signal of water gauge and flow meter, outputs each calculated and determined control signal as flow control of flow control valve and start and stop control of the submerged pump, and controls the amount of water supply.

    • 要解决的问题:提供一种通过尽可能地减少潜水泵的启动和停止频率来减少流入的泥沙的细颗粒的井装置和井装置的控制方法,并且抑制总水 供应成本最低。

      解决方案:控制系统在模拟供水开始时间,供水预计完成时间以及总供应成本成为每个时间段和每个时区的定期供水量之前决定水下泵供水开始之前 最低,基于水位计的测量信号和预定的需求模式; 在潜水泵供水开始后,控制系统根据水表和流量计的测量信号随时计算每个设定时间间隔的目标供水量,将每个计算和确定的控制信号作为流量输出 控制流量控制阀,启动和停止对潜水泵的控制,并控制供水量。 版权所有(C)2005,JPO&NCIPI

    • PROBLEM TO BE SOLVED: To correct the nonconformity of a pumping control system to the nature of ground water. SOLUTION: The levels of water in pumping wells W equipped with motor-driven valves 8 positioned at a few points and water in observation wells located at a few points to correspond to the pumping wells W are measured by means of monometers 9 and the like, and the aperture of each motor-driven valve 8 is automatically controlled in real-time at an accuracy of 0.1% for a 100% of fully opening so that the difference between a set level of water and a measured level of water is dissolved. When the difference (well loss) in level of water between inside and outside of the casing of the pumping well W is large and when the rate of decrease in level of ground water is slow, the amount of water pumped from each well is measured with an electromagnetic flowmeter 12 or the like, and the permeation characteristic of the ground required to estimate the relationship between the flow rate of pumped water and the level of the ground water is automatically calculated through reverse analysis from the measurements of the amount of water pumped from the pumping well W and the level of water in the observation well A during system operation. The present level of the ground water is estimated from the measurement of the amount of water pumped, and the aperture of each motor-driven valve 8 is automatically controlled in real-time at an accuracy of 0.1% for a 100% of fully opening, so that the difference between the present level of the ground water and the set level of the ground water is eliminated.
