In contrast to using water flowing in rivers, rivers, and the like where general water falls, the Mondridge or the Monaridap of the present embodiment mean rice fields that can be farmed with water stored in reservoirs, and are also called beneficiaries. The Monji (230, beneficiary) has many advantages, such as the use of water stored in the reservoir as a spring water due to the effect of farmland improvement projects, such as to increase the yield.

As shown, the water stored in the water source 210 in each of the villages 230 is guided through the water passage 220.

In the present embodiment, the central control unit 110 is installed in a general control station that can collectively control the water supply of the Monridge 230. In addition, it controls each component installed at the point necessary for the control of the water supply. In addition, the central control unit 110 receives the measurement data transmitted from each component in order to control and control the water supplied to the paddy field as a whole to calculate a signal for controlling the operation of each component, and then again By transmitting to the devices, the water supply is controlled. In addition, the central control unit 110 by inputting the number of times, such as the amount of water to be supplied, the number of water to be supplied, such as water to be supplied to the corresponding village (230), water supplied to the corresponding village (230) If it is under or oversupply, it can be set to control automatically.
