Expert control system and control method based on batch coating machine

Abstract

The invention discloses an expert control system based on a batch type coating machine. The system comprises a coating machine, an image detection system and an expert system. The expert system consists of a control cabinet and a display screen; a human-computer interaction interface, a knowledge base module, an inference engine module, a feedback self-learning module and a control center are arranged in the control cabinet; the control center is an industrial personal computer electrically and bidirectionally connected with the human-computer interaction interface, the feedback self-learningmodule and a PLC control module of the coating machine respectively; the human-computer interaction interface is in electrical output connection with the knowledge base module; the feedback self-learning module is in electrical output connection with the inference engine module; and a signal input terminal of the feedback self-learning module is further in signal connection with a signal output terminal of an image detection system and is used for receiving the coating qualification rate fed back by the image detection system. According to the invention, the processing parameters are automatically optimized and combined for different seeds; the efficiency is improved, the dosage of a coating agent is saved, and the effect is remarkable on the premise of meeting the coating quality and qualification rate.

Description

technical field [0001] The invention belongs to the technical field of seed coating, and in particular relates to an expert control system and a control method based on a batch coating machine. Background technique [0002] Seed coating technology can effectively prevent and control pests and diseases, protect seed growth, improve seed vitality, reduce environmental pollution, reduce production costs, and promote crop production and harvest. It has huge economic and ecological benefits, and is an important way to realize mechanization of seed processing and standardization of improved varieties , has been widely used all over the world. The seed coating machine has a history of nearly one hundred years and has developed rapidly in my country in recent years. The design of the traditional seed coating machine is more focused on the mechanical part. The electronic control system uses a simple device, which is difficult to achieve precise control. It cannot make all parts work...

AI Technical Summary

Problems solved by technology

At present, there is little research on the expert system of the coating machine. Yang Wanxia and others built an expert system with a single-chip microcomputer as the core to achieve the purpose of precise coating, but further improvement is needed in terms of knowledge acquisition and reasoning rules.

In addition, the design of the traditional seed coating machine is more focused on the mechanical part. The electronic control system uses a simple device and requires manual participation. It is difficult to achieve precise control, and it cannot make all parts work in an orderly manner. The processing parameters depend on the experience of the operator. , the degree of intelligence is low, which seriously restricts the improvement of seed coating quality
