Embodiment Construction

[0015] The wireless system for fast near-infrared detection of grain quality of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0016] Such as figure 1 The rapid detection wireless system shown includes a wireless acquisition device and an information center. The wireless acquisition device collects optical absorption signals in the near-infrared spectrum region on site, and transmits the signals to the information center through the GPRS network and the Internet in turn; the information center receives the wireless acquisition device. The transmitted signal is processed to obtain the corresponding fatty acid value.

[0017] The wireless acquisition device is based on the optical absorption characteristics of various representative organic components in the grain (rice, wheat, corn) in the near-infrared spectrum region, the difference in the strongest absorption wavelength of each component, and the relationship ...

Abstract

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.

Description

technical field [0001] The invention relates to a wireless system for fast near-infrared detection of grain quality. Background technique [0002] According to the provisions of GB / T20569-2006 in the Judgment Rules for Rice Storage Quality, GB / T20571-2006 in the Judgment Rules for Wheat Storage Quality, and G13 / T20570 in the Judgment Rules for Corn Storage Quality, the fatty acid value in grain is the main factor for its storage quality. One of the indicators. Therefore, when the grain depot purchases these three staple grains in the grain production area, the determination of the fatty acid value is particularly important. The determination of the fatty acid value of the grain is usually carried out in the laboratory, usually by titration, colorimetry and chromatographic analysis. , the detection accuracy of these methods is high, but the time is long, the cost is high and professional personnel are required to operate. In recent years, portable near-infrared rapid gr...
