To provide a falling detection device, a falling detection system, a falling detection method and a falling detection program with which it is possible to quickly detect and respond to an event that abnormality has occurred to an optical scanner.SOLUTION: A falling detection device 4 detects a person having fallen from a station platform to a rail track on which a train passes, the device comprising a signal reception unit 11 and a control unit 10. The signal reception unit 11 acquires, from upper and lower scanners 31, 32 that scan light within a prescribed angle range in a falling detection area that is set onto the rail track and receive reflected light of the light, RAW data of the reflected light of the light having been radiated under a given condition, for each prescribed angle, as reference data, and acquires received light data of the reflected light of the light having been radiated from the upper and lower scanners 31, 32. The control unit 10 compares data acquired by a measurement data acquisition unit with the reference data acquired by the signal reception unit 11, and determines whether or not the upper and lower scanners 31, 32 are inclined according the difference exceeds a prescribed threshold or not.SELECTED DRAWING: Figure 2
【課題】光走査器に異常が生じたことを速やかに検知して対処することが可能な転落検知装置、転落検知システム、転落検知方法および転落検知プログラムを提供する。【解決手段】転落検知装置4は、駅のプラットホームから列車が通過する軌道上へ転落した人を検知する装置であって、信号受信部11と、制御部10とを備えている。信号受信部11は、軌道上に設定された転落検知エリアにおいて所定の角度範囲内で光を走査し光の反射光を受光する上・下走査器31,32から一定の条件下において照射された光の反射光のRAWデータを所定の角度ごとに基準データとして取得し、上・下走査器31,32から照射された光の反射光の受光データを、所定の角度ごとに取得する。制御部10は、信号受信部11において取得された基準データと比較して所定の閾値を超えるか否かに応じて、上・下走査器31,32の傾きの有無を判定する。【選択図】図2
