注水肉超声波无损检测装置及特征阈值的提取

Ultrasonic nondestructive testing device for water-injected meat and extraction of feature threshold

针对注水肉问题与缺少民用注水肉检测装置的情况,研制了基于超声波能量分析的便携式注水肉无损检测装置,并通过试验对频率分级特征、特征半波、δ_0幅值等特征量值进行分析,以确认注水肉检测的特征阈值。研究结果表明:注水肉检测特征半波δ_0的幅值4.010V为阈值;验证实验结果证明该装置对宰后注水肉的分级精度达到98.8%。

Targeting the water-injected meat issue and lack of the household inspective devices, developed a portable non-destructive ultrasonic inspective device on water injected meat. Basing on the ul- trasonic energy analysis, the final characteristic threshold is confirmed hy analyzing characteristic values, like the characteristics of frequency, characteristic half-wave, andS0 amplitude, through re lated experiments. As the results imply, 4.010 V, the obtained 80 amplitude of characteristic half-wave, is the final threshold. The non- destructive ultrasonic inspective device on water injected meat reaches a high grading accuracy of 98.8%.
