To provide an abnormal sound detection device, an elevator device, a method, and a program which reduce misdetection of abnormal sound by ambient sound other than that of a moving body to be monitored.SOLUTION: An abnormal sound detection device according to an embodiment comprises a first sound collection unit, an abnormality detection unit, a position information input unit, a history storage unit, and an integration determination unit. The first sound collection unit is installed in the moving body and collects operation sound of the moving body. The abnormality detection unit detects abnormal sound of the operation sound. The position information input unit accepts input of position information of the moving body. The history storage unit stores history information in which detection results in which abnormal sound has been detected and the position information are associated with each other. The integration determination unit determines presence and absence of abnormality of the moving body by integrating the detection results per each piece of the position information on the basis of the history information.SELECTED DRAWING: Figure 2
【課題】監視対象となる移動体以外の周囲の音による異常音の誤検知を低減すること。【解決手段】実施形態に係る異常音検知装置は、第1集音部と、異常検知部と、位置情報入力部と、履歴格納部と、統合判定部と、を備える。前記第1集音部は、移動体に設置され、前記移動体の稼働音を集音する。前記異常検知部は、前記稼働音のうちの異常音を検知する。前記位置情報入力部は、前記移動体の位置情報を入力する。前記履歴格納部は、前記異常音を検知した検知結果と、前記位置情報とを関連付けた履歴情報を格納する。前記統合判定部は、前記履歴情報に基づいて、前記位置情報毎に前記検知結果を統合することにより、前記移動体の異常の有無を判定する。【選択図】 図2
