Abstract

　機体の異常／故障診断を、閾値を用いることなく行なえる機体診断システムを提供する。エンジン出力と関連する信号の大きさと出現頻度との関係を表わす頻度分布情報を機体11の一定時間稼働ごとに生成する動態管理用コントローラ24と、複数の頻度分布情報を受信して蓄積する管理部15と、管理部15から入手した複数の頻度分布情報を時系列に並べて比較することでエンジン出力の低下を検知する端末機器17，19とによって、機体診断システムを構成する。従来の閾値との比較で異常／故障判定したり異常度合いをランク付けする場合と異なり、エンジン出力に関して蓄積された複数の頻度分布情報間の比較により、エンジン出力低下を、閾値を用いることなく検知できる。
