Description
この発明に係る倒れ検知装置においては、転倒を検出する走査範囲である検知エリアに水平面状にレーザビームを放射するスキャン型距離センサとを備え、スキャン型距離センサは、床面から8〜11cmの高さとなるように設置され、測定した角度毎の距離を蓄積し、予め設定した検知エリア内のデータに対しその時間的な距離変化に基づいて倒れ状態と判定するものであって、予め設定した検知エリア内のデータに対しその時間的な距離変化に対する標準偏差及び標準偏差の標準偏差を計算し、標準偏差の標準偏差が閾値以下の場合、その領域の物体の表面サイズ(長さ)を計算し、物体の表面サイズ(長さ)が閾値以上の状態が所定の継続時間持続すると、倒れ状態と判定するものである。 In the fall detection device according to the present invention, the detection area which is a scan range for detecting a fall includes a scan type distance sensor that emits a laser beam in a horizontal plane, and the scan type distance sensor is 8 to 11 cm from the floor surface. It is installed to be at a height, accumulates the distance for each measured angle, and determines the fall state based on the temporal distance change with respect to the data in the preset detection area . Calculates the standard deviation and standard deviation of the deviation over time for the data in the detection area. If the standard deviation of the standard deviation is less than the threshold, the surface size (length) of the object in that area is calculated. When the state where the surface size (length) of the object is equal to or greater than the threshold value continues for a predetermined duration, it is determined that the object is in a fallen state .
また、この発明に係る乗客コンベアにおいては、乗客コンベアの乗り場と降り場となる各乗降口にそれぞれ設置され、乗客コンベアのステップ側にくし板が設けられている乗降用床板と、乗降用床板の反くし板側に設けられた乗客が接近するためのアプローチ用通路と、乗客コンベアの乗降口付近に設置され、乗降用床板及びアプローチ用通路を含む走査範囲に水平面状にレーザビームを放射するスキャン型距離センサとを備え、スキャン型距離センサは、床面から8〜11cmの高さとなるように設置され、測定した角度毎の距離を蓄積し、予め設定した検知エリア内のデータに対しその時間的な距離変化に基づいて倒れ状態と判定するものであって、予め設定した検知エリア内のデータに対しその時間的な距離変化に対する標準偏差及び標準偏差の標準偏差を計算し、標準偏差の標準偏差が閾値以下の場合、その領域の物体の表面サイズ(長さ)を計算し、物体の表面サイズ(長さ)が閾値以上の状態が所定の継続時間持続すると、倒れ状態と判定するものである。
Further, in the passenger conveyor according to the present invention, a boarding board for boarding / exiting, which is installed at each boarding gate for landing and landing of the passenger conveyor and provided with a comb board on the step side of the passenger conveyor, An approach passage provided on the side of the warp plate for approaching the passenger and a scan installed in the vicinity of the entrance / exit of the passenger conveyor to emit a laser beam in a horizontal plane to the scanning range including the boarding floor plate and the approach passage The scan type distance sensor is installed so as to have a height of 8 to 11 cm from the floor, accumulates the distance for each measured angle, and sets the time for the data in the preset detection area. distances be those determined state collapse based on the change, and the standard deviation for the temporal distance changes to data in the previously set the detection area When the standard deviation of the quasi-deviation is calculated, and the standard deviation of the standard deviation is less than or equal to the threshold, the surface size (length) of the object in that area is calculated, and the state where the surface size (length) of the object is greater than or equal to the threshold is predetermined If it continues for the duration of, it will be judged as a fall state .
