ABNORMALITY DETECTION DEVICE, WATER GATE SYSTEM, AND ABNORMALITY DETECTION METHOD
To detect an abnormality at a water gate facility suitably.SOLUTION: An abnormality detection device 40 detects the abnormality at a water gate facility having a door body for adjusting a circulation of water and a water gate opening/closing device for opening/closing the door body. The abnormality detection device 40 comprises a detection part 49 obtaining a measurement value of a detection object with a weight applied to a coupling medium coupling a drive part and the door body or a load applied to the drive part at the water gate opening/closing device as the detection object, an immersion amount obtain part 41 obtaining the immersion amount of the door body, a normal value estimation part 42 estimating the normal value of the detection object at least based on the immersion amount, and a determination part 43 deciding a presence of the abnormality at the water gate facility by comparing the measurement value obtained by the detection part 49 and the normal value estimated by the normal value estimation part 42. Thus, the abnormality at the water gate facility can be suitably detected.SELECTED DRAWING: Figure 2
【課題】水門設備における異常を適切に検出する。【解決手段】異常検出装置４０は、水の流通を調整するための扉体と、扉体を開閉する水門開閉装置とを備える水門設備において異常を検出する。異常検出装置４０は、水門開閉装置において駆動部と扉体とを連結する連結媒体にかかる荷重、または、駆動部にかかる負荷を検出対象として、検出対象の測定値を取得する検出部４９と、扉体の没水量を取得する没水量取得部４１と、検出対象の正常値を、少なくとも没水量に基づいて推定する正常値推定部４２と、検出部４９により取得される測定値と、正常値推定部４２により推定される正常値とを比較することにより、水門設備における異常の有無を判定する判定部４３とを備える。これにより、水門設備における異常を適切に検出することができる。【選択図】図２
