SLUICE GATE CONTROL APPARATUS, SLUICE GATE, SLUICE GATE CONTROL METHOD, AND SLUICE GATE CONTROL SYSTEM
To provide a sluice gate control apparatus, a sluice gate, a sluice gate control method, and a sluice gate control system which can reduce a difference between a water level of a farm field and an appropriate water level of a field crop.SOLUTION: A sluice gate control apparatus 2 has: a storage part 22 which stores a changed water level history showing a changed water level in which a water level of a farm field has changed in a weather state of a farm field area including a farm field; an apparatus information acquisition part 231 which acquires weather forecast information showing the weather state of the farm field area in a predetermined period which has been forecast; a water level specifying part 232 which specifies the current water level of the farm field; an estimation part 233 which estimates an estimated changed water level in which the water level of the farm field changes in a predetermined period on the basis of the weather state of the farm field area shown by the weather forecast information and a changed water level in the weather state of the farm field area shown by the changed water level history; and a sluice gate control part 234 which controls an inflow which is an amount of the water that a sluice gate 1 allows to flow into the farm field on the basis of the current water level and the estimated changed water level of the farm field such that the total of evaluation values set for each water level of the farm field in a predetermined period becomes a maximum.SELECTED DRAWING: Figure 3
【課題】圃場の水位と農作物の適正水位との差を小さくすることができる水門制御装置、水門、水門制御方法及び水門制御システムを提供する。【解決手段】圃場を含む圃場エリアの気象状態において圃場の水位が変化した変化水位を示す変化水位履歴を記憶する記憶部２２と、予報された所定の期間における圃場エリアの気象状態を示す気象予報情報を取得する装置情報取得部２３１と、圃場の現在水位を特定する水位特定部２３２と、気象予報情報が示す圃場エリアの気象状態と、変化水位履歴が示す圃場エリアの気象状態における変化水位とに基づいて、所定の期間において圃場の水位が変化する推定変化水位を推定する推定部２３３と、圃場の現在水位と推定変化水位とに基づいて、所定の期間における、圃場の水位ごとに設定された評価値の合計が最大になるように、水門１が圃場に流入させる水の量である流入量を制御する水門制御部２３４と、を有する水門制御装置２。【選択図】図３
