自走式奶牛精确饲喂机的单片机控制系统设计

Design of MCU Control System on Self-propelled Precise Feeding Machine for Cows

为了提高奶牛精确饲喂技术水平、降低成本、减少工作量、提高个体奶牛产奶量,在前期完成自走式奶牛精确饲喂机机械结构设计和牛场信息管理系统设计的基础上,通过单片机控制系统的设计,实现奶牛饲喂数据的接收、牛只的个体精确识别、装备的行进及精确投料,实现了个体奶牛的自动化及智能化饲喂。试验调试验证表明:饲喂机的最佳行进速度为0.6m/s,识别距离达65cm,系统响应时间为0.4s;个体奶牛识别率96%,个体牛只识别正确率100%,给料误差小于2%。

In order to improve precise feeding technology for cows,cut down cost,decrease workload,and improve milk production of single dairy cow. On the basis of design of the mechanical structure and for self- propelled precise feeding machine and the information management system for dairy farm,the design of MCU control system was completed in this paper. The cow feeding data receiving and the recognition of the cows individual accurately were achieved,the travel of the equipment and precise feeding were realized. Automation and intellectualization were implementation. The experimental results showed that the best rate of the precise feeding machine was 0. 6m / s. The recognition distance of card reader was 65 cm. The response time of machine was 0. 4s. The control system can identify 96% of the single dairy cow correctly. The feeding error was controlled at below 2%.
