Grain quality near infrared rapid detection wireless system

The invention discloses a grain quality near infrared rapid detection wireless system, and the system comprises a wireless acquisition device and an information center, wherein the wireless acquisition device is used for acquiring optical absorption signals in a field near infrared spectral region and transmitting the signals to the information center through a GPRS (general packet radio service) network and the Internet; the information center is used for receiving the signals transmitted by the wireless acquisition device and processing the signals; the information center comprises an evaluation model and analysis device, and after the evaluation module and analysis device receives the signals transmitted by the wireless acquisition device, a model is established, and grain samples are analyzed through the established model; the establishment of the model comprises the establishment of a grain database, the pretreatment of data, the trial establishment of the model, the evaluation of the model and the determination of the model; and the analysis of the grain samples comprises the selection of the model, the analysis of components, the post-treatment and the result evaluation of the analysis of the grain samples, and the corresponding fatty acid value is obtained. By utilizing the system, the remote real-time grain quality detection can be realized, and the acquisition cost of grain can be further saved.
