To identify the location of abnormal sounds, the component that generates the abnormal sounds, and the cause of the occurrence from sound data that includes the abnormal sounds among sounds generated by an elevator.SOLUTION: First, a traveling position of an elevator at the time when sound data including abnormality is generated and a generation position of the sound data are calculated by acquiring the sound data and traveling position data at the time when the elevator is traveling by a sound sensor and a position sensor. Then, information on material of parts of the elevator at the traveling position and the generating position at the time when the sound data including the abnormal sound is generated is extracted so as to calculate the parts with the material that emit this sound data including the abnormal sound through learning the sound data including the abnormal sound. The material information of the parts of the elevator is compared with the material that emits the sound data including the abnormal sound, and the cause of the sound data including the abnormal sound is identified based on the result of the comparison.SELECTED DRAWING: Figure 1
【課題】昇降機が発生する音のうち異常音を含む音データから、その発生箇所と発生部品及び発生原因を特定する。【解決手段】まず、音センサーと位置センサーにより昇降機の走行時の音データと走行位置データを取得し、異常を含む音データの発生時の昇降機の走行位置と、この音データの発生位置を算出する。次に、異常音を含む音データ発生時の走行位置と発生位置における昇降機の部品の材質情報を抽出し、異常音を含む音データを学習させて、この異常音を含む音データを発する材質を有する部品を算出する。そして、昇降機の部品の材質情報と、異常音を含む音データを発する材質とを比較し、比較の結果に基づいて異常音を含む音データの発生原因を特定する。【選択図】図1
