[8]本発明の一実施形態は、音情報を取得する取得ステップと、音情報を取得する位置に関する位置情報を受け付ける受付ステップと、音信号の周波数解析を行って得られた複数の解析結果の中から選択された解析結果であって、前記取得ステップで取得された音情報の周波数解析を行って得られた解析結果および前記受付ステップで受け付けられた位置情報に基づいて選択された解析結果と、当該選択された解析結果に対応づけられた情報との、少なくとも一方を表示する表示ステップと、を備えた診断方法である。
[9]本発明の一実施形態は、音情報を取得する取得ステップと、音情報を取得する位置に関する位置情報を受け付ける受付ステップと、音信号の周波数解析を行って得られた複数の解析結果の中から選択された解析結果であって、前記取得ステップで取得された音情報の周波数解析を行って得られた解析結果および前記受付ステップで受け付けられた位置情報に基づいて選択された解析結果と、当該選択された解析結果に対応づけられた情報との、少なくとも一方を表示する表示ステップと、をコンピュータに実行させるためのプログラムである。
端末装置10には、画像形成装置20を表示した画面上に、画像形成装置20を6分割する補助線90,91,92が重ねて表示されている。
この3本の補助線90,91,92が、画像形成装置20を6つの領域a,領域b,領域c,領域d,領域e,領域fに分割するように表示される。図8では、装置の方向を示す正面画像Aであるとの情報が加えられ、3本の補助線90,91,92が、領域Aa、領域Ab、領域Ac、領域Ad、領域Ae、領域Afに分割するように表示されている。ユーザが画面上の領域Aa,領域Ab,領域Ac,領域Ad,領域Ae,領域Afのいずれかを選択して指65でタッチ操作(以下、タップと記す)することにより、録音位置を指定できる。指定された録音位置は、録音位置情報として制御部33に受け付けられる。
具体的には、図9に示すように、ユーザが画面上の画像形成装置20の画像を左右にスライドさせるようなタップをする度に、画像形成装置20の姿勢が、正面画像Aから左側面画像D又は右側面画像Bへ、右側面画像Bから正面画像A又は背面画像Cへ、背面画像Cから右側面画像B又は左側面画像Dへ、左側面画像Dから背面画像C又は正面画像Aへと変化する。また、上下にスライドさせるようなタップする度に、正面画像A、右側面画像B、背面画像C又は左側面画像Dから天面画像Eに変化し、天面画像Eから正面画像A、右側面画像B、背面画像C又は左側面画像Dへ変化する。すなわち、ユーザの操作に基づいて、画面上の画像形成装置20の異なる方向の外観ごとに、録音位置情報が変化される。また、各画像B~Eは、正面画像Aと同様に6分割する補助線90,91,92が重ねて表示され、右側面画像Bは、領域Ba,Bb,Bc,Bd,Be,Bfに分割されている。背面画像Cは、領域Ca,Cb,Cc,Cd,Ce,Cfに分割されている。左側面画像Dは、領域Da,Db,Dc,Dd,De,Dfに分割されている。天面画像Eは、領域Ea,Eb,Ec,Ed,Ee,Efに分割されている。この3本の補助線90,91,92は、装置情報、装置の向き等によって、装置を分割する領域が異なるように配置される。
ここでは、画像形成装置20の外観のイラスト画像を用いて説明したが、画像形成装置20の外観の写真画像を用いてもよい。また、画面上を左右上下にスライドさせるようなタップをすると説明したが、これに限らず、画面上に回転矢印キーを設けて、回転矢印キーをタップすることで画像を回転するようにしてもよい。
すなわち、ユーザが音情報を取得する画像形成装置20の外観の方向を指定し、さらに装置の外観の分割された領域を指定することにより、異音の録音位置が、録音位置情報として受け付けられる(ステップS102)。
ステップS205において生成された抽出リストのうち、位置情報が一致すると判定された波形データが選択されて、優先的に抽出される(ステップS207)。そして、生成された抽出リストの全ての波形データにおいて、ステップS206の判定がされたか否かが判定される(ステップS208)。
このように、異音の発生原因パーツや部品番号を指定して表示するようにしてもよい。
上記実施形態では、録音位置情報に基づく動作をサーバ装置50側で行う場合を用いて説明したが、これに限られない。この動作は、端末装置10側で行うようにしてもよい。
また、本開示は上記の実施の形態に何ら限定されるものではなく、本開示の要旨を逸脱しない範囲で種々の形態で実施することができる。
本出願は、2015年12月25日出願の日本特許出願(特願2015-254322)に基づくものであり、それらの内容はここに参照として取り込まれる。
