PROBLEM TO BE SOLVED: To obtain a flood gate measurement device capable of measuring a state of a flood gate without attaching a limit switch or position sensor on the flood gate's body or opening/closing mechanical device.SOLUTION: A flood gate measurement device comprises: a transmission unit for transmitting a distance measurement wave to an object; a reception unit for receiving a reflection wave of the distance measurement wave transmitted from the transmission unit; a distance measurement unit for measuring a distance to the object from a delay time between the distance measurement wave transmitted from the transmission unit and the reflection wave received by the reception unit; a constant holding unit for holding a relational expression or table indicating relation between a distance to the object and the degree of openness of the flood gate; a position calculation processing unit for calculating the degree of openness of the flood gate by using the distance measured by the distance measurement unit and the relational expression or table held by the constant holding unit; and a digital position signal conversion unit for converting the flood gate's degree of openness calculated by the position calculation processing unit to one of digital position signals including fully-open and fully-closed position signals.SELECTED DRAWING: Figure 1
【課題】水門の本体または開閉機械装置にリミットスイッチや位置センサを取付けなくても、水門の状態を測定できる水門測定装置を得ることを目的とする。【解決手段】水門測定装置は、測距波を対象物に向けて発信する発信部と、発信部から発信された測距波の反射波を受信する受信部と、発信部から発信された測距波と受信部で受信された反射波の遅延時間から対象物までの距離を測定する測距部と、対象物までの距離と水門の開度の関係を示す関係式またはテーブルを保持する定数保持部と、測距部で測定された距離と定数保持部に保持されている関係式またはテーブルを使って水門の開度を算出する位置演算処理部と、位置演算処理部で算出された水門の開度を、全開と全閉を含むデジタル位置信号に変換するデジタル位置信号変換部と、を備えている。【選択図】図１
