Control system and control method of small-size agricultural product intelligent sorting machine based on DSP

Abstract

The invention discloses a control system and control method of a small-size agricultural product intelligent sorting machine based on a DSP, and belongs to the technical field of classification and sorting in agricultural product processing. The control system comprises a material horizontal conveying device, an illuminating system, a real-time image capture and analysis system, an image capture triggering and sorting triggering system and a sorting system. The sorting system is connected with the tail end of the material horizontal conveying device, the illuminating system is arranged on the material horizontal conveying device, and the real-time image capture and analysis system and the image capture triggering and sorting triggering system are arranged above the illuminating system. According to the control system and control method, a DSP chip serves as the visual core of the intelligent sorting machine and replaces a common PC, real-time image capture, processing and analysis are achieved independently, capture triggering and sorting triggering are achieved through a single chip microprocessor and an optoelectronic switch to achieve control over sorting, therefore, a machine visual system is low in cost, high in integration level and high in processing speed, and real-time image capture, analysis and sorting can be carried out at the same time.

Description

technical field [0001] The invention relates to the technical field of grading and sorting in agricultural product processing, in particular to a control system and control method of a small-scale intelligent sorting machine for agricultural products based on DSP. Background technique [0002] The intelligent sorting machine based on the principle of machine vision has been gradually applied to the classification or sorting of various agricultural products in recent years, and this technology will become the mainstream of the development of agricultural product sorting technology in the future. [0003] The core of the machine vision unit of the machine vision sorting machine (intelligent sorting machine) currently on the market is generally an ordinary PC (or workstation), and a small number of them use the form of "PC + DSP". Among these sorting machines, the PC To complete the image collection, analysis and control functions of the system, DSP is only used for image proce...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problems of low cost, multi-purpose (suitable for various types of agricultural product sorting) and light simplification (light, simple, compact structure) and other problems based on machine vision sorting equipment, and overcome the existing intelligent sorting machine. Aiming at the large-scale post-harvest processing and centralized sales of fruits and vegetables, resulting in a large structure of sorting equipment, high cost, and unsuitable for small-scale processing and sales of farmers, family farms, etc., a DSP-based small-scale intelligent sorting machine for agricultural products is provided The control system and control method to reduce the purchase cost of the machine vision unit in the intelligent sorting machine
