Near-infrared spectroscopy has the advantages of fast and non-destructive, and is widely used in agricultural products, chemical industry, medicine and other industries. In recent years, miniaturized and miniaturized near-infrared spectrometers have become the development direction in this field, and are used for rapid on-site testing outside the laboratory. The NIR Workshop (NIRW) led by Professor Chen Bin of Jiangsu University has been devoted to the basic and applied research of near-spectral analysis. American JDSU successfully developed the world's smallest near infrared spectrometer (Micro NIR 1700). NIRW concentrated its efforts and developed the [Analysis and Detection System Based on JDSU Miniature Near-Infrared Spectrometer] for Windows system in July 2013. The system software includes two parts. One is auxiliary modeling, which can build and save models. The second is spectrum analysis, which can realize spectrum acquisition, model loading, model calculation and real-time display of results. On this basis, the team carried out the development and research of the rapid detection software system based on the Android system handheld device. After Yan Yan and Zhang Suofi's painstaking efforts, they finally achieved success. It can use the Android mobile phone and tablet to control the collection of the spectrometer and combine the input model to preprocess the spectrum (smoothing, derivation, normalization, etc.), PLS and other calculations, so as to realize the real-time display of the detection index.
