Zusammenfassung: | To provide an information processing device with which it is possible to identify, and record as a log, a detailed classification of received vibration and mechanical shock.SOLUTION: An information processing device comprises an acceleration sensor and a control unit. The acceleration sensor preserves, in a first storage unit, an acceleration data group for a prescribed number of measurements and having been measured after acceleration, when acceleration exceeds at least a first threshold. The control unit calculates an inclination of jerk norm, acceleration amplitude and a frequency of the acceleration data group. Meanwhile, the control unit classifies the acceleration data group for the prescribed number of measurements into one of high-frequency vibration, low-frequency vibration and mechanical shock on the basis of the inclination of jerk norm, the acceleration amplitude and the frequency and determines a level of vibration or mechanical shock. The control unit preserves, in a second storage unit, a log that indicates the classification result of the acceleration data group for the prescribed number of measurements and the determination result of the level of vibration or mechanical shock.SELECTED DRAWING: Figure 1
【課題】受けた振動および衝撃の詳細な分類を特定し、ログとして記録することができる情報処理装置を提供する。【解決手段】情報処理装置は、加速度センサと、制御部とを備える。加速度センサは、加速度が少なくとも第1の閾値を超える場合に、加速度以降に計測された規定の計測回数分の加速度データ群を第1の記憶部に保存する。制御部は、加速度データ群のジャークノルムの傾きと加速度振幅と周波数とを算出する。また、制御部は、ジャークノルムの傾きと加速度振幅と周波数とに基づいて規定の計測回数分の加速度データ群を高周波振動、低周波振動、および衝撃のいずれかに分類し、振動または衝撃のレベルを判定する。制御部は、規定の計測回数分の加速度データ群の分類結果と動または衝撃のレベルの判定結果とを示すログを第2の記憶部に保存する。【選択図】図1 |
