Problems solved by technology

Both are laboratory instruments with large volume and weight, and the sampling position is fixed, which cannot eliminate the measurement error caused by uneven sample loading
Since it cannot be detected in real time on site, the efficiency is low and the cost is high
[0004] The "Portable Near-infrared Mineral Analyzer" disclosed in CN03127633.4 adjusts the incident light through a light modulator, and the reflector and optical path are arranged in an integrating sphere. Cannot be used for the detection of food crops
CN200720093240.6 discloses "Ethanol Gasoline Optical Fiber Analyzer" based on "Portable Near Infrared Mineral Analyzer", which tests the composition and content of ethanol gasoline through fiber optic probes. For the detection of food crops

Abstract

The invention relates to a portable near infrared spectrometric analyzer for on site detecting soy quality, which is includes a light source, a sampling system, a optical splitting system, a signal collection, a singlechip and an up position machine. Composite light emitted by the light source is diffuse transmitted by sample, is split by the optical splitting system to obtain appointed wave band near infrared monochromatic light beam, the near infrared monochromatic light beam irradiates to a array type sensor and translates to a corresponding electric signal, the electric signal translates to a digital signal by a digital-analog converter and is transmitted to the up position machine by a USB interface. Absorbency spectrum data is obtained by detection signal of the sample, spectrogram of the sample is displayed, and constituents of soy sample are analyzed according to the spectrum data. Design of rotation sample pool can measure diffuse transmission spectrum signal of the sample at different angle, eliminate measurement error due to asymmetrical loading, increase speed and date accuracy of near infrared spectrum detection, need no pretreatment of the sample and solve problem of difficult on site detection analysis for soy and other grain crop.

Description

technical field [0001] The invention relates to a device for on-site grain detection, in particular to a near-infrared spectrum analysis instrument suitable for on-site detection of soybean quality. Background technique [0002] The quality analysis of soybean and its products is of great significance to guide the high-quality production and deep processing utilization of soybean main producing areas, and improve the market competitiveness of soybean products. The existing quality detection method has a cumbersome pretreatment process and a long detection time. For a long time, due to the limitations of traditional analysis techniques, the raw material purchase system of agricultural products based on quality and price has not been well resolved. Unable to meet the requirements of follow-up, follow-up inspection and follow-up storage. When buying soybeans, the grade of soybeans is determined only by the color, smell, and impurity content of soybeans. The quality of soybeans...
