Automation Control System Of Fruit Bag

With the development of the society, people's living standard continuously improved, so as to the quality of the items requested are also constantly improving. Fruit is essential in people's lives, it can provide many nutrients for people's body, in a variety of fruits, the apple is the greatest demand, apple sales have been increasing in recent years. In order to improve the quality of the apple, it began to use apple bagging, after bagging can prevent pesticides and harmful substances in the air on the fruit of pollution, pollution-free food production is one of the important means of producing apple. Apple bagging technology applications solve the fruit quality and pollution problems in the production of high practical value. Although the use of the fruit bags can improve the apple's quality in a certain extent, most of apple's high-grade fruit from the quality is still a certain gap that China's apple production ranked the highest in the world, but exports of high-end apple is far from satisfactory. And the low price, high pass rate of ecological fruit bag is the key to solve this problem.This paper carried out analysis and study bags about research background, the significance of the development of the status at home and abroad and, with its national conditions and growers to consider the affordability of the proposed research topic goal is to design high precision, correcting speed, since the strong adaptability, dynamic real-time monitoring of the situation and having a good processing stability of the sterile fruit bag control system to improve the original fruit bag machine automation, fruit garden industry adapt to the industrialization of the process.The main topics for the production of fruit bag , on the original basis of research and design designs a fruit bag of high automation, mainly divided into mechanical systems and control systems. Mechanical transmission system to meet the main transmission of paper, bags outside the incision, cut, folded, stacked bags of blank paper and control of displacement; control system from the corresponding sensors, signal processing systems, anti-jamming design, drive system and a drive equipment, mainly to complete deviation signals in the collection, processing, fault monitoring and motor drive. Sterile bag of fruit in the control system used AT89C51 as the core processor, a dedicated drive the chip to ensure that not only between different parts of the system can also coordinate action to ensure that the acquisition signals in real time.Use of the modular system software programming ideas, use KEILC51 and compilation of mixed-language programming, embodies the C51 language flexibility, the simplicity of procedures and maintenance procedures for compatibility, and reflects the compilation of language control the precise time Software modules include data acquisition, alarm module, modules and drive module. Part of each module has a corresponding routine, when the functional needs of the module, in the main program through the realization of the function call subroutine modules function.The system of bags of fruit production lines can be monitored in real-time, so that users have mastered working conditions, and accurate grasp of the situation. In addition, other aspects of the system also were discussed.
