Pendulum Is Seedlings Pot Seedling Machine Single Chip Microcomputer Automatic Dry Field Seedling Control Research

With the exploitation of agriculture, applied in agricultural machines are constantly being developed. Mechanization has become an important symbol of modern agriculture. Agricultural science and technology in continuous development, previously, old-fashioned farming methods have also changed, gradually changing from extensive farming to intensive agriculture, and promoting and adjusting the structure of China’s rural industries and agricultural economy. Make it more in-depth, ongoing optimization, continuous improvement, and played a very significant role and gained very significant results. In the process of agricultural production, for popularization of the range used by mechanization is gradually, and its effects will gradually emerge. will create a new situation for agricultural machinery.Plant operations plays an important role in agricultural production, seedling transplanting technique, based on automatic migration for seedlings, to reduce labor intensity, the liberation of labor productivity, improve the efficiency of transplant is of great significance. At present, has not set foot in a suitable field study on plug seedlings of full-automatic transplanting machine for the job, while the study of greenhouse intelligent machines are still in the experimental stage, its control system exists: high positioning accuracy, flexibility and reliability control unstable performance, lower intelligence; efficiency problems. Plug seedlings mechanism of automatic picking seedling is one of the key parts of the automatic transplanting machine in the field,according to a new type of plug seedlings mechanism of automatic picking seedling.First seedling consists of mechanical and control system consists of two parts, this paper focuses on this part is a seedling machine control system, first of all, the system was designed,completed the pendulum seeding machine set it manually according to the request of speed, the number of horizontal and vertical moving rice bowl, and seedlings can be more accurate when it is launched. Secondly, hardware design, including the selection, selection of servo motor, sensor selection combined with the modular design, design of the power supply module, control systems,signal acquisition module, and according to their function and design a circuit through isolation and earth method to increase the immunity system. And hardware control PCB Board wasreasonable design and wiring. Finally, software design, is also in accordance with the modular design concept, pendulum seeding mechanism control system research and development software.The programming language used is C51, keil u vision4 is the development environment to develop the software, while using the STC-ISP burning software to burn the complete program written.While analysis and design of the main program flow charts, signal acquisition and program flow chart, press the key to enter the program and shows the program flow chart.Experimental results show that: use of the control system of seeding machine to reduce the labor intensity, and the entire system is stable and reliable.
