基于DSP的便携式猪肉品质无损快速检测装置的研发
Development of portable device based on dual-DSP for nondestructive detection of pork freshness
摘要
Abstract
This study was to develop a new offline portable detection system for nondestructive detection of pork freshness,including hardware and software designs with a main digital signal processor(DSP) TMS320DM6437 and an auxiliary DSP TMS320F28015.The hardware system consisted of a high-power LED point light source unit,an image acquisition unit,a dualDSP data processing unit and a LCD display unit.In addition,the software system was designed with C programming language in the CCS3.3 the development environment.The detection system was able to predict pork total volatile basic nitrogen(TVB-N) value,pH value and pork color(L*,a * and b * values).The prediction correlation coefficient of validation set (RV)was 0.92 with prediction standard error(SEP)of 2.03 for TVB-N,RV was 0.90 with SEP of 0.04 for pH value,Rv was 0.94 with SEP of 1.02 for L*;RV was 0.90 with SEP of 0.80 for a *;RV was 0.91 with SEP of 0.58 for b*.After debugging and experiment of the hardware and software system,it was verified that the detection speed of the developed system was 4 seconds per sample.In conclusion,the portable device meets the requirements of the site rapid detection in pork meat industrials.关键词
