WATER GATE OPENING NOTIFICATION DEVICE, WATER GATE OPENING NOTIFICATION SYSTEM, WATER GATE OPENING NOTIFICATION METHOD, AND PROGRAM
To provide a water gate opening notification device optimizing output frequency of the opening notification related to the water gate opening.SOLUTION: A water gate opening notification device 4 includes: a data collection unit 42 which sequentially acquires opening data converted from the opening pay load of a water gate 2, defines the absolute value of a variation rate of the latest opening variation as the latest variation width v1, defines the absolute value of the variation rate of opening variation immediately before the latest opening variation as a previous variation width v2, and stores the latest variation width v1 and the previous variation width 2 in a memory 47; an opening/closing speed reduction detection unit 43 which, when the previous variation width 2 is a threshold th1 or more and the latest variation width v1 is less than the threshold th1, outputs the opening notification showing the latest opening data providing the latest variation width v1; and a fine opening/closing detection unit 44 which outputs the opening notification showing the latest opening data, when the previous variation width v2 and the latest variation width v1 are less than the threshold th1 and the absolute value of the variation rate from the opening data included in the latest output opening notification to the latest opening data is a threshold th2 or more, which is less than the threshold th1.SELECTED DRAWING: Figure 1
【課題】水門開度に関する開度通知の出力頻度を適正化する門開度通知装置を提供する。【解決手段】水門開度通知装置４は、水門２の開度ペイロードから変換される開度データを逐次取得し、最新の開度変化の変化率の絶対値を最新変化幅ｖ１と定義し、最新の開度変化の直前の開度変化の変化率の絶対値を直前変化幅ｖ２と定義し、最新変化幅ｖ１及び直前変化幅ｖ２をメモリ４７に記憶するデータ収集部４２と、直前変化幅ｖ２が閾値ｔｈ１以上でありかつ最新変化幅ｖ１が閾値ｔｈ１未満である場合に、最新変化幅ｖ１を与えた最新の開度データを示す開度通知を出力する開閉減速検出部４３と、直前変化幅ｖ２及び最新変化幅ｖ１が閾値ｔｈ１未満でありかつ最後に出力された開度通知に含まれる開度データから最新の開度データへの変化率の絶対値が閾値ｔｈ１未満の閾値ｔｈ２以上である場合に、最新の開度データを示す開度通知を出力する微開閉検出部４４と、を含む。【選択図】 図１
