摘要: The invention discloses an impact detection method executed in a computing device. comprises: vibration signal of to-be-detected device within predetermined time is obtained and domain waveform determined based on the signal; positive envelope determined; plurality wave peaks at are classified into two classes amplitudes average value first types used as energy, wherein amplitude type peak islarger than that second peak; according to interval between adjacent peaks, waves groups,wherein total number groups density duration all time; main frequency component frequency; frequency, density,and time, severity degree, determined. Besides, also corresponding
