The embodiment of the invention relates to a passenger conveyor diagnosis device and a step diagnosis method. The device for diagnosing abnormal sound generated during running of a plurality of steps connected into a ring is provided with a sound collection part, a calculation part and an abnormal sound analysis part. The sound collecting part is arranged at the middle part in the height direction of a step on the going side and a step on the returning side in a truss of the passenger conveyor, and more than two microphones are arranged at adjacent positions. The calculation part calculates the generation direction of the abnormal sound according to the arrival time difference or the volume difference between the adjacent microphones on the basis of the driving sound collected by the sound collection part when the passenger conveyor runs. The abnormal sound analysis unit determines a step in which abnormal sound is generated on the basis of the calculated generation orientation.

    本发明的实施方式涉及乘客输送机诊断装置以及梯级诊断方法。对多个梯级连结为环状的梯级在行驶时产生的异响进行诊断的装置具备集音部、计算部、以及异响分析部。集音部设置在乘客输送机的桁架内的去路侧的梯级与归路侧的梯级的高度方向的中间部,在邻接的位置上具有两个以上的麦克风。计算部基于乘客输送机行驶时由集音部收集到的行驶音,根据邻接的麦克风间的到达时间差或者音量差来计算异响的产生方位。异响分析部基于计算出的产生方位来确定产生异响的梯级。
