Rapeseed quality non-destructive testing method and device based on near infrared spectrum technology

Abstract

The invention discloses a rapeseed quality non-destructive testing method and a device based on a near infrared spectrum technology. For the device, a sample chamber is inserted inside an integrating sphere, an incident light source, the sample chamber and a tester are integrated on a casing of the integrating sphere by fully utilizing the structural characteristics of the integrating sphere, andthe device comprises a spectrum signal collection device, a microcomputer and a result display device; and the method comprises the following steps of: transmitting received spectrum signals into themicrocomputer by the tester at the stage of rapid testing through building a correlation model of such quality indexes as moisture content, fat content and the like of rapeseeds and corresponding spectrum signals; and calling model parameters of corresponding quality by the microcomputer and performing calculation to obtain such quality indexes as the moisture content, fat content and the like ofthe rapeseeds so as to realize the non-destructive testing of quality of rapeseeds. The invention has the advantages of high testing accuracy, good result consistency, high automatic degree and the like, not only provides monitoring basis for acquisition process of primary products, but also further creates conditions for standardized grades of primary products based on quality.

Description

technical field [0001] The invention relates to a non-destructive detection method and device for agricultural product quality, in particular to a rapid non-destructive detection method and device for rapeseed quality based on near-infrared spectroscopy technology. Background technique [0002] Agricultural products are the necessities of people's life. my country has a large population and is a big country in the production and consumption of agricultural products. The safety and quality of agricultural products are of vital significance to the harmony and stability of our society. However, at present, the production and sales of agricultural products in my country's rural areas are still mainly purchased by township purchase points and agricultural product processing enterprises. The characteristics are: many purchase points, large dispersion range, short purchase time and large purchase quantity. The pricing of raw materials is relatively random, and the purchaser often d...
