To provide an abnormality diagnostic system capable of appropriately diagnosing abnormality of a governor rope at the occurrence of earthquake and the like.SOLUTION: An abnormality diagnostic system diagnoses abnormality of a governor rope, which is stretched between a governor arranged on an upper part of a hoistway of an elevator and a tensioner sheave arranged on a lower part of the hoistway and moves in association with the elevation of a car. The abnormality diagnostic system includes a sensor, a waveform generation unit, and an abnormality determination unit. The sensor measures a rotation angle or an inclination angle of a movable link that supports the tensioner sheave to be displaceable in the vertical direction of the hoistway. The waveform generation unit starts to acquire a measurement value of the sensor when receiving an earthquake detection signal from an earthquake sensor and generates a waveform showing temporal change of the rotation angle or the inclination angle of the movable link after the detection of the earthquake. The abnormality determination unit determines abnormality of the governor rope based on the waveform generated by the waveform generation unit and transmits a signal corresponding to a determination result.SELECTED DRAWING: Figure 1

    【課題】地震発生時などにガバナロープの異常を適切に診断できる異常診断システムを提供する。【解決手段】実施形態の異常診断システムは、エレベータの昇降路上部に配置されたガバナと昇降路下部に配置されたテンショナシーブとの間に張り渡されて乗りかごの昇降に伴って移動するガバナロープの異常を診断する異常診断システムであって、センサと、波形生成部と、異常判定部と、を備える。センサは、テンショナシーブを昇降路の上下方向に変位可能に支持する可動リンクの回転角または傾斜角を測定する。波形生成部は、地震感知器から地震検知信号を受信するとセンサの測定値の取得を開始し、地震検知後の可動リンクの回転角または傾斜角の時間変化を表す波形を生成する。異常判定部は、波形生成部により生成される波形に基づいてガバナロープの異常判定を行い、判定結果に応じた信号を送信する。【選択図】図1
