PROBLEM TO BE SOLVED: To provide an abnormality diagnostic device for a passenger conveyor which can detect an abnormal roller at an initial stage such that a sound is not generated.SOLUTION: An abnormality diagnostic device for a passenger conveyor comprises: an acceleration sensor (11) for measuring an amount of vibration of a rail on which a foot step roller attached to a foot step of the passenger conveyor runs; and a controller (12) which extracts a section, in which an amount of vibration exceeding a preset threshold is continuously measured during a preset duration time or longer, as an abnormal vibration section on the basis of a change-with-time of an amount of vibration measured by the acceleration sensor during constant speed travel of the foot step, and specifies the abnormal roller on the basis of a time corresponding to a peak amount of vibration in the abnormal vibration section.SELECTED DRAWING: Figure 3
【課題】音の発生しない初期段階での異常ローラを検出できる乗客コンベアの異常診断装置を得る。【解決手段】乗客コンベアの踏段に取り付けられた踏段用ローラが走行するレールの振動量を測定する加速度センサ(11)と、踏段が定速走行中に加速度センサにより測定された振動量の経時変化に基づき、あらかじめ設定した閾値を超える振動量が、あらかじめ設定した継続時間以上連続して測定された区間を異常振動区間として抽出し、異常振動区間の中のピーク振動量に対応する時刻から、異常ローラを特定する制御器(12)とを備える。【選択図】図3
