Portable grain quality rapid nondestructive detection and identification device

Abstract

The invention belongs to the technical field of agricultural product detection, and relates to a portable grain quality rapid nondestructive detection and identification device which comprises a shell, a spectrum acquisition unit, a data transmission and processing unit, a circuit unit and a heat dissipation unit. The spectrum acquisition unit is used for acquiring spectrum information of to-be-detected grains, and the data transmission and processing unit is used for processing, calculating and storing data; and a micro processing system in the data transmission and processing unit is internally provided with different quality prediction models of different types of to-be-detected grains, the micro processing system calculates quality index parameters of an object to be detected according to the corresponding models, the grade of the detected grains is identified according to the detected indexes, and a detection result is displayed on a liquid crystal display screen in real time. According to the invention, diffuse reflection light is used for spectral analysis so that the precision and the stability are better; multiple varieties and multiple indexes can be detected at the same time, and the device is high in universality; single-time multi-quantity measurement can be realized, the operation is convenient, and the efficiency is high; and the whole device is small, light and easy to carry.

Description

technical field [0001] The invention belongs to the technical field of agricultural product detection, and relates to a portable rapid non-destructive detection and identification device for grain quality. Background technique [0002] Cereal food mainly provides carbohydrates, protein, dietary fiber and B vitamins for the human body, and is the main source of human heat energy. However, due to the constraints of many factors such as geography, environment, pests and diseases, and pesticides, the shape, color, and internal nutritional content of grains are quite different, which has different effects on the value and safety of grains. Moreover, with the continuous improvement of people's requirements for the quality of life, the internal and external quality of grains has been paid more and more attention by people. Therefore, it is of great significance to develop a method and device that can quickly and massively detect the quality of various grains. [0003] Traditional...
