Method and device for automatically sorting winter jujubes

Abstract

The invention provides a method and a device for automatically sorting winter jujubes. The method comprises the following steps: sequentially collecting spectral diffuse reflection data of all winterjujubes transmitted at a preset speed in a specified characteristic waveband; calculating quality prediction physical and chemical indicators by using a pre-constructed winter jujube quality prediction model according to the spectral diffuse reflection data information; and comparing the quality prediction physical and chemical indicators with preset quality standard physical and chemical indicators, and determining the quality level of the winter jujubes. The method and the device realize the fine sorting of the winter jujubes, so large-area damages of the winter jujubes in a whole box, caused by entrance of damaged winter jujubes to the long-distance transportation packaging box, are reduced, and classified sales of consumers having different demands are realized to facilitate the improvement of the overall sales values of the winter jujubes.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to an automatic sorting method for winter jujubes and an automatic sorting device for winter jujubes. Background technique [0002] With the development of precision agriculture and the advancement of agricultural modernization, the commercialization of agricultural and sideline products has become an important trend to increase farmers' income and promote national economic growth. As the first link of the winter jujube industry chain, the quality sorting of winter jujube is an important means and key link to realize the commercialization of winter jujube and improve the quality of products. [0003] In the related technology, only the size of the winter jujube is sorted, or the appearance is sorted manually. On the one hand, it is difficult to accurately sort and classify the winter jujube. Minor damage caused by factors such as collisions, extrusions, falls, etc., ...

AI Technical Summary

Problems solved by technology

[0003] In the related technology, only the size of the winter jujube is sorted, or the appearance is sorted manually. On the one hand, it is difficult to accurately sort and classify the winter jujube. Minor damage caused by factors such as collision, extrusion, fall, etc. in a short period of time is difficult to distinguish only by visually observing the appearance changes of winter jujube, and it is easy to cause large-area damage to the whole box of winter jujube due to slightly damaged winter jujube.
