Description
Claims (1)
- 正常な稼働音の特徴量が突発的に変化する対象物の異常を検知する異音検知装置であって、
前記対象物から取得された振動に由来する入力信号の特徴量時系列を第1信号として算出し、
前記第1信号から、時間軸上の中央領域に存在する中間特徴量時系列である第2信号と、前記第1信号から前記第2信号を取り除いた欠損後特徴量時系列である第3信号を、それぞれ算出し、
予め、対象物が正常であるときの第3信号を入力として、第2信号を予測する写像を学習しておき、前記写像を用いて前記第3信号から中間特徴量時系列である第4信号を予測し、
前記第2信号と前記第4信号との誤差に基づいて、前記対象物の異常を検知するものであって、
正常な稼働音と異常な稼働音の時間変化が前記第1信号の中に収まるように前記第1信号の長さは設定されており、前記第2信号の期間は、前記第2信号が前記第3信号の情報のみから予測できないように設定される
異常検知装置。
