PROBLEM TO BE SOLVED: To achieve a detection function of passengers walking on a passenger conveyor and a function for determining whether passengers are on one side of a passenger conveyor having the size of a footstep which two passengers can get on side by side, at a lower cost than before.SOLUTION: A safety device for a passenger conveyor includes: a first detector (6) for detecting passengers passing by on a traveling direction left side of the passenger conveyor; a second detector (6) for detecting passengers passing by on a traveling direction right side of the passenger conveyor; a pattern generation section (11) for generating first time series data and second time series data on the basis of each detection signal by both of the detectors; and a passenger state determination section (12) for estimating the number of passengers walking in each of right and left traveling directions and the number of passengers standing and stopping on footsteps from the lengths of ON states in the first time series data and the second time series data and estimating a deviation state of passengers by comparing the number of the left side passengers with the number of the right side passengers, which are calculated on the basis of the estimation result.SELECTED DRAWING: Figure 3

    【課題】従来よりも低コストで、乗客コンベアを歩行している乗客の検出機能、および乗客2人が並んで乗れる大きさの踏段を有する乗客コンベアにおいて乗客が片側に片寄っているか否かを判断する機能を実現する。【解決手段】乗客コンベアの進行方向左側を通過する乗客を検知する第1検出器(6)と、乗客コンベアの進行方向右側を通過する乗客を検知する第2検出器(6)と、両検出器によるそれぞれの検出信号に基づいて第1時系列データおよび第2時系列データを生成するパターン生成部(11)と、第1時系列データおよび第2時系列データにおけるON状態の長さから、左右それぞれの進行方向で歩行している乗客数、踏段上に立ち止まっている乗客数を推定するとともに、推定結果に基づいて算出した左側乗客数と右側乗客数とを比較することで乗客の片寄り状況を推定する乗客状態判断部(12)とを備える。【選択図】図3
