【摘要】：研究了一種基于傳感器陣列優(yōu)化的儲存山參品質(zhì)檢測方法。實(shí)驗(yàn)記錄氣體傳感器陣列對山參樣品的響應(yīng)信號,采用傳感器載荷分析的方法對傳感器陣列響應(yīng)信號進(jìn)行優(yōu)化。優(yōu)化后傳感器陣列主成分區(qū)分度提高了10.46%。優(yōu)化后傳感器陣列檢測信號輸入非線性數(shù)據(jù)共振模型,基于系統(tǒng)輸出互相關(guān)系數(shù)COE(Cross Correlation Coefficient,)特征值經(jīng)由線性擬合方法構(gòu)建儲存山參品質(zhì)檢測模型Q=(COE_(max)-0.23)/0.02(R~2=0.990 26)。驗(yàn)證實(shí)驗(yàn)結(jié)果表明所構(gòu)建的模型的預(yù)報(bào)準(zhǔn)確度為83.3%。所探索的方法有望在儲存中藥材品質(zhì)檢測領(lǐng)域得到廣泛應(yīng)用。
[Abstract]:A quality detection method based on sensor array optimization for storage of Panax japonicus was studied. The response signals of gas sensor array to Panax ginseng samples were recorded experimentally. The sensor array response signal is optimized by the method of sensor load analysis. After optimization, the principal component differentiation of sensor array increases 10.46. After the optimization, the sensor array detection signal is input into the nonlinear data resonance model. Based on the COE(Cross Correlation coefficient) eigenvalue of the system output, the quality detection model Q=(COE_(max)-0.23)/0.02(R~2=0.990 26 was constructed by linear fitting. The experimental results show that the prediction accuracy of the proposed model is 83.3%. The field of quality detection of stored Chinese medicinal materials has been widely used.
