PROBLEM TO BE SOLVED: To prevent flooding damage in a drainage channel upstream of a water gate and a water quality standard excess in a drain port downstream of the water gate, by eliminating manual operation of opening the water gate at a job site.SOLUTION: A system is provided for controlling opening of the water gate for making water of the drainage channel upstream of the water gate flow to the drainage channel downstream of the water gate from the upper side of a gate plate, by lowering and opening the gate plate by a lifting mechanism. The water gate opening control system comprises an opening determination device for determining the opening of the water gate for satisfying a predetermined standard on a water quality in the drain port for connecting the drainage channel to a public water area, by inputting a detection result of a water quality in the drainage channel upstream of the water gate and a water quality in the drainage channel downstream of the water gate and a detection result of a water level and a flow speed in the drainage channel upstream of the water gate and a water level and a flow speed in the drainage channel downstream of the water gate and an opening control device for controlling the opening of the water gate based on the opening determined by the opening determination device.
【課題】現場での水門の開放の手動操作を排除するとともに、水門よりも上流の排水路での冠水被害および水門よりも下流の排水口での水質基準超過を防止することにある。【解決手段】昇降機構でゲート板を下降させて開き、水門よりも上流の排水路の水を前記ゲート板の上側から水門よりも下流の排水路に流す水門の開度を制御するシステムにおいて、前記水門よりも上流の排水路での水質と前記水門よりも下流の排水路での水質との検出結果と、前記水門よりも上流の排水路での水位および流速と前記水門よりも下流の排水路での水位および流速との検出結果と、を入力されて、前記排水路を公共水域に繋げる排水口での水質が所定基準を満たす前記水門の開度を決定する開度決定装置と、前記開度決定装置が決定した開度に基づき前記水門の開度を制御する開度制御装置と、を具えることを特徴とする水門開度制御システムである。【選択図】図１
