Design of Automatic Milking Controller

Milking machine automatic control is not only an important part for dairy farm to achieve of digital management, but also one of the key development of animal husbandry. Milking machine automatic control can improve production efficiency of dairy farm and quality of raw milk. First, the need of the milking factory is known, and an automatic control requirement is developed. Secondly, an AVR microcontroller core AT90CAN128 of ATMEL, used as the centre of the controller. And then, the hardware system is designed in several modules. In the last, the software of the controller is designed in detail based on certain need. The project uses the research method of combination of experimetal research, analytical studies and lessons learned. First the paper designs the hardware circuit board and the software development of the milking machine controller. Then through debugging of the physical machine, the paper implements the function of milking automatically and cleaning automatically. The results has reached the milk production expectations, and achieved good effects.
