OBSTACLE DETECTION DEVICE, ELECTRIC SHUTTER, OBSTACLE DETECTION METHOD, AND OBSTACLE DETECTION PROGRAM
To accurately detect an obstacle even when various shutters are adopted.SOLUTION: An obstacle detection device 100 detects an obstacle which is an obstacle to the operation of a shutter 2 for opening/closing an opening of a building. The obstacle detection device 100 includes a motor current value acquisition unit 44 for acquiring a motor current value of a current flowing in a motor 3 for operating the shutter 2, a difference calculation unit 44 for calculating a current difference which is a difference between a first current value indicating the motor current value and a second current value indicating the motor current value acquired before the motor current value based on the first current value, a ratio calculation unit 44 for calculating a current ratio which is a ratio of the first current value to the second current value, and a determination unit 44 for determining a presence or absence of the obstacle on the basis of the current difference and the current ratio.SELECTED DRAWING: Figure 2
【課題】種々のシャッターを採用した場合であっても、障害物を精度良く検知すること。【解決手段】障害物検知装置１００は、建物の開口部を開閉するシャッター２の動作の障害となる障害物を検知する。この障害物検知装置１００は、シャッター２を動作させるモーター３に流れる電流のモーター電流値を取得するモーター電流値取得部４４と、モーター電流値を示す第１の電流値に対する第１の電流値に基づくモーター電流値よりも前に取得されたモーター電流値を示す第２の電流値の差である電流差を算出する差算出部４４と、第２の電流値に対する第１の電流値の比である電流比を算出する比算出部４４と、電流差及び電流比に基づいて、障害物の有無を判定する判定部４４とを備える。【選択図】図２
