WATER LEVEL DETECTION SYSTEM AND WATER LEVEL DETECTION METHOD
To provide a water level detection system allowing its installation to be carried out in an easy way and in low cost.SOLUTION: A water level detection device 2 is provided with: a signal supply unit 28 for supplying high frequency signals to a specific ladder 12b of a plurality of ladders 12a to 12j supported on an inner peripheral wall of a manhole 4 and placed along a vertical direction with intervals so as to radiate electric waves in the manhole 4 from the specific ladder 12b; a receiving antenna 30 installed in the manhole 4, the receiving antenna 30 being arranged to receive a composite wave including radiated waves from the specific ladder 12b and reflected waves from a water surface in the manhole 4; and a detection unit 32 for detecting a water level in the manhole 4 based on a received power of the composite wave received with the receiving antenna 30.SELECTED DRAWING: Figure 2
【課題】容易に且つ安価に設置することができる水位検出システムを提供する。【解決手段】水位検出システム２は、マンホール４の内周壁に支持され且つ上下方向に沿って間隔を置いて配置された複数のタラップ１２ａ～１２ｊのうち、特定のタラップ１２ｂからマンホール４内に電波が放射されるように、特定のタラップ１２ｂに高周波信号を供給する信号供給部２８と、マンホール４内に配置された受信アンテナ３０であって、特定のタラップ１２ｂから放射され且つマンホール４内の水面で反射された電波を含む合成波を受信する受信アンテナ３０と、受信アンテナ３０で受信された合成波の受信電力に基づいて、マンホール４内の水位を検出する検出部３２とを備える。【選択図】図２
