Cereal color sorting control system

Abstract

The invention discloses a cereal color sorting control system. The cereal color sorting control system is characterized by comprising a main control board, wherein the main control board is connected with a human-computer interface, a DSP board, a motor driver board and a PLC board; the DSP board is connected with a CCD board and an indicator board; the motor driver board is connected with a background board angle adjusting system; the PLC board is connected with a feeder, a light source, a sweeping system, an air valve driver board and the motor driver board; the feeder is connected with a vibrator, and the air driver board is connected with an electromagnetic valve. Compared with the prior art, the cereal color sorting control system has the advantages that stability, reliability, economy and flexibility are achieved, the small, exquisite and complete control system is formed through expansion of an output port of a single chip microcomputer of the main control board, real-time control and adjustment of all working parts are achieved, the color sorting rate is improved, and the bring-out rate is reduced; the control system can be conveniently transplanted into other systems.

Description

technical field [0001] The invention relates to a grain color sorting control system. Background technique [0002] The grain color sorter is based on the differences in the optical properties of grains, using photoelectric sensing technology, digital image processing technology and microcomputer control technology to sort out the bad materials with different colors, surface defects or internal deterioration from a large number of materials. A photoelectric non-destructive testing device. It distinguishes and sorts the different-colored grains and impurities by the color of the product, especially when the particle size and density of unqualified grains and qualified grains are very similar, color sorting becomes the only sorting method. [0003] The color sorter comprehensively utilizes new technologies in the disciplines of modern optics, photoelectric sensing, image processing, electronic control and computer applications, and is a typical high-tech product integrating l...

Problems solved by technology

The disadvantage of this control method is that it depends on the experience of experts and cannot be controlled and adjusted in real time; the disadvantage of this control method is that it relies on the experience of color sorting by experts, and cannot control and adjust the various working parts of the color sorter in real time. , so it will affect the stability and reliability of the color sorter, and then make the two major indicators to measure the performance of the color sorter: low color sorting rate and high take-out rate. Specifically, the following points:

[0005] 1. Due to the low resolution of the image sensor, the angle of the light source and the background plate cannot be intelligently controlled, so it cannot intelligently meet the color sorting requirements of different grains, and it is difficult to select bad grains such as heterochromatic grains and tiny disease spots;

[0006] 2. Because the color sorter cannot be intelligently controlled, the output of grain sorting is low, and the whole machine is too large to be easily moved;

[0007] 3. The resolution of the photoelectric sensor is low, and the noise of the collected image signal is large, which directly affects the color sorting effect;

[0008] 4. The consistency and reliability of electronic components are not high, which affects the stability of the product
