WATER GATE MONITOR CONTROL DEVICE, WATER GATE MONITOR SYSTEM, WATER GATE MONITOR METHOD, AND COMPUTER PROGRAM THAT CAUSES COMPUTER TO IMPLEMENT THE WATER GATE MONITOR METHOD
To provide a water gate monitor installation capable of detecting debris that stays at the bottom of a gate door of a water gate to interrupt the closure of the gate door, and of enhancing reliability of the closure of the gate door.SOLUTION: A water gate monitor installation consists of: a network communication section 117 to obtain multiple images that are captured with cameras 21a, 21b, 21c which take pictures of multiple positions along the flow direction of a river or a canal; a flow speed/direction meter 17 to obtain flow-direction information that shows the flow direction of water; a debris detection section 111 which assesses time sequence of the images based on the flow direction information and distinguishes the debris by making comparison between the images taken earlier and those taken later to detect the debris that flows in the river or canal; a debris flow-speed calculation section 113 which calculates the flow speed of the detected debris based on their positions and the time at which the debris is detected in the river or canal; and an interference determination section 115 which determines based on the calculated flow speed of the debris whether or not the debris will become obstruction to the closure of a gate door 13 of a water gate 3.SELECTED DRAWING: Figure 2
【課題】水門においてゲート下に留まり、ゲート閉鎖を妨げる異物を検出し、ゲート閉鎖の信頼性を高めることができる水門監視装置を提供する。【解決手段】河川または水路の流れ方向に沿う複数の位置を撮影するカメラ２１ａ、２１ｂ、２１ｃによって撮影された複数の画像を取得するネットワーク通信部１１７、水の流れ方向を示す流向情報を取得する流速・流向計１７、流向情報から画像の時系列を判定し、先に撮影された画像と後に撮像された画像とを比較して異物の異同を判定して河川または水路を流れる異物を検出する異物検出部１１１と、検出された異物の河川または水路における位置及び時刻に基づいて、異物の流速を算出する異物流速算出部１１３と、算出された異物流速に基づいて、異物が水門３のゲート１３を閉じる障害になり得るか否かを判定する障害判定部１１５と、により水門監視装置を構成する。【選択図】図２
