To provide a fall detection system capable of accurately determining whether a passenger has fallen, and a passenger conveyor equipped with the same.SOLUTION: A fall detection system 41 is a system for monitoring falls of passengers on an escalator 10, and comprises an upstream detection unit PF that detects objects transported by an endless transport body 30 (see Figure 1), a downstream detection unit PR that is adjacent to the detection unit PF and detects objects transported by the endless transport body 30, and a fall presence/absence determination unit 43 that determines that a passenger has fallen if a calculated value U1 calculated from a detection time T1 of an object at the upstream detection unit PF and a transport speed V of the endless transport body 30 is equal to or greater than a threshold value α, and if a calculated value U2 calculated from a detection time T2 of the object at the downstream detection unit PR and the transport speed V becomes equal to or greater than the threshold value α within Δt time after the value U1 becomes equal to or greater than the threshold value α.SELECTED DRAWING: Figure 4
【課題】乗客の転倒判定を精度よく行うことが可能な転倒監視システムおよびこれを備えた乗客コンベアを提供する。【解決手段】転倒監視システム41は、エスカレータ10における乗客の転倒を監視するシステムであって、無端搬送体30(図1参照)によって搬送される物体を検知する上流側検知部PFと、同検知部PFに隣接し無端搬送体30によって搬送される物体を検知する下流側検知部PRと、上流側検知部PFにおける物体の検知時間T1と無端搬送体30の搬送速度Vとから算出される算出値U1が閾値α以上である場合において、同値U1が閾値α以上となってからΔt時間以内に下流側検知部PRにおける物体の検知時間T2と上記搬送速度Vとから算出される算出値U2が閾値α以上となることを条件に乗客が転倒していると判定する転倒有無判定部43とを備える。【選択図】図4
