Problem to be solved: to reduce the burden on the water management of the farmer by making use of the information communication technology to set the opening and closing of an automatic irrigation automatic water supply plug, set the upper and lower water level, set the opening and closing time, and confirm the water level in the field.The present invention relates to a conventional automatic water supply valve for controlling a water stop by raising and lowering a water pressure by an open air valve mechanically opened and closed by a movement of a float floating on the water surface, and an air opening valve 2 for opening and closing with an electric signal, and water level When the sensor 7 detects the water level of the field and deviates from the set water level, the atmospheric open valve 2 is opened or closed by an electric signal to reduce or raise the water pressure, thereby opening or closing the water stop valve 21 of the water supply main body 17.Further, by installing the radio module 10, it is possible to set the upper and lower water levels of the field from the portable terminal 16 at a remote location, to instruct the opening and closing of the water stop valve 21, to set the opening \/ closing time, and to confirm the water level in the field Make possible.Diagram【課題】本発明は、情報通信技術を使って、既存の潅漑用自動給水栓の開閉や上限・下限の水位の設定、開閉時間の設定及び圃場の水位の確認を、遠隔からできるようにし、農業者の水管理にかかる負担軽減を図る。【解決手段】本発明は、水面に浮かぶフロートの動きで機械的に開閉する大気開放弁により水圧を上下させることで止水弁を制御する従来の自動給水栓について、電気信号で開閉する大気開放弁2を用いるとともに、水位センサー7で圃場の水位を検知して設定した水位の範囲から逸脱した場合は、電気信号で大気開放弁2を開閉させることにより、水圧を低下又は上昇させることで給水栓本体部17の止水弁21を開閉させる。また、無線モジュール10を搭載することで、離れた場所の携帯端末16から、圃場の上限・下限水位を設定できるようにするほか、止水弁21の開閉を指示したり、開閉時間を設定したり、圃場の水位を確認することを可能とする。【選択図】図1
