To provide a simple, inexpensive system for diagnosing an abnormal sound of an elevator.SOLUTION: In an elevator abnormal sound diagnostic system according to an embodiment, when a determination that an abnormal sound is emitted is made based on sound pressure measurement data created by measurement of each of sound sensors, a time difference between points in time at which sound pressure peak values of the sound pressure measurement data are generated is calculated as a measurement time difference. Based on the measurement time difference, a direction in which an abnormal sound is emitted with respect to a reference point defined by each sound sensor is calculated as a measurement emission direction. An abnormal sound emission device that has emitted the abnormal sound is specified based on the measurement emission direction and device arrangement data at an elevation position of an elevator car at which the sound pressure peak value has been generated.SELECTED DRAWING: Figure 3

    【課題】簡素で安価なエレベータの異常音診断システムを提供する。【解決手段】実施の形態によるエレベータの異常音診断システムにおいては、各々の音センサの測定により作成された音圧測定データに基づいて異常音が発生していると判定された場合、各々の音圧測定データの音圧ピーク値が発生した時刻の時刻差を測定時刻差として算出する。この測定時刻差に基づいて、各々の音センサから画定される基準点に対する異常音の発生方角を測定発生方角として算出し、この測定発生方角と、音圧ピーク値が発生した乗りかごの昇降位置における機器配置データとに基づいて、異常音を発生させた異常音発生機器が特定される。【選択図】図3
