description To reduce a possibility that a human error may occur, and to obtain a further exact diagnosis result.SOLUTION: A mechanical performance diagnosis device for diagnosing the soundness of an operation of a construction machine is provided, the mechanical performance diagnosis device comprises: a storage device storing fundamental waveform data of a plurality of operations of the construction machine, and performance and allowable error values of the plurality of operations; and a processor performing processing for diagnosing the soundness of the construction machine. The processor performs: processing for identifying an actually performed operation by comparing sensor waveform data which are obtained by detecting the actually performed operation of the construction machine by a sensor, and the waveform data which are held in the storage device; and processing for determining the soundness of the construction machine by acquiring a performance reference value and the allowable error value corresponding to a specified operation from the storage device, and comparing the acquired performance reference value and the allowable error value, and a characteristic value of the actually performed operation.SELECTED DRAWING: Figure 2 【課題】ヒューマンエラーが起こる可能性を低減し、かつより正確な診断結果を得る。【解決手段】本開示は、建設機械の動作の健全性を診断する機械性能診断装置であって、建設機械の複数の動作それぞれの基準波形データと、複数の動作それぞれの性能基準値および許容誤差値と、を格納する記憶デバイスと、建設機械の健全性を診断するための処理を実行するプロセッサと、を備え、プロセッサは、建設機械の実際に実行された動作をセンサで検知して得られるセンサ波形データと、記憶デバイスに保持されている基準波形データとを比較することにより、実際に実行された動作を特定する処理と、特定された動作に対応する性能基準値および許容誤差値を記憶デバイスから取得し、当該取得した性能基準値および許容誤差値と実際に実行された動作の特徴値とを比較し、建設機械の健全性を判定する処理と、を実行する、機械性能診断装置を提案する。【選択図】図2
