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 based on sound pressure measurement data generated by measurement of each sound sensor, a time difference between times at which a sound pressure peak value of each sound pressure measurement data is generated is calculated as a measurement time difference. On the basis of the measurement time difference, the generation orientation of the abnormal sound relative to a reference point defined by each sound sensor is calculated as a measurement generation orientation, and an abnormal sound generation device for generating the abnormal sound is determined on the basis of the measurement generation orientation and device configuration data at the lifting position of the passenger car where the sound pressure peak value is generated.
本公开涉及电梯的异常声音诊断系统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制作的声压测定数据判定为产生了异常声音的情况下,算出产生各个声压测定数据的声压峰值的时刻的时刻差作为测定时刻差。基于该测定时刻差,算出相对于根据各个声音传感器划定的基准点的异常声音的产生方位作为测定产生方位,基于该测定产生方位和产生声压峰值的乘用轿厢的升降位置处的设备配置数据,确定产生异常声音的异常声音产生设备。
