The invention relates to an abnormal sound diagnosis system and an abnormal sound diagnosis method of an elevator. In an abnormal sound diagnosis system of an elevator according to an embodiment, when it is determined that an abnormal sound is generated on the basis of sound pressure measurement data created by measurement of each sound sensor, the time difference at which the sound pressure peak value of each sound pressure measurement data appears is calculated as a measurement time difference. On the basis of the measurement time difference, the generation position of the abnormal sound relative to a reference point in the upper surface of the passenger car is calculated as a measurement generation position, and on the basis of the measurement generation position and the equipment configuration data at the lifting position of the passenger car where the sound pressure peak value occurs, the abnormal sound generation equipment which causes the abnormal sound is determined.

    本发明涉及电梯的异常声音诊断系统以及异常声音诊断方法。在实施方式的电梯的异常声音诊断系统中,在基于通过各个声音传感器的测定而创建的声压测定数据,判定为产生了异常声音的情况下,计算各个声压测定数据的声压峰值出现的时刻的时刻差作为测定时刻差。基于该测定时刻差,计算相对于乘用轿厢的上表面中的基准点的异常声音的产生位置作为测定产生位置,并基于该测定产生位置、和在出现声压峰值的乘用轿厢的升降位置处的设备配置数据,确定引发异常声音的异常声音产生设备。
