Design and implementation of NIRS coal quality detection system
NING Shi-mao
Abstract：In order to reduce the testing cost and provide technological guarantee for high mineral samples nondestructive examination,and combining with the technological principle of Near Infrared test,the design and development of online testing system of NIRS were demonstrated from two aspects(hardware system design and software system design),object-oriented programming technology was used to realize the functions like spectrum acquisition,spectrogram display,the pretreatment of spectrum,establishment of calibration model and prediction of unknown samples under various parameter settings,the partial least squares quantitative model of coal quality moisture content was established, we found that the square of correlation coefficient of calibration set was 0.947 and correlation coefficient of prediction set was 0.888,the root-mean-square error of calibration set was 0.46 and the root-mean-square error of prediction set was 0.55,which meant that the prediction ability was relatively good,and the application prospect would be good.
