Based on the technology of personal computer and wireless transmission, a kind of self-propelled precise feeding machine control system for single dairy cow was designed. This kind of control system can realize the precise feeding of single dairy cow based on their physiological characteristics by using the technology of RFID and MCU. Using this system, the intelligent identification for single dairy cow and the information transmitted from personal computer to MCU by air were realized. The dual-mode moving and accurate feeding was achieved. The experimental results showed that the best rate of the precise feeding machine was 0. 6 m/s. The response time of the machine was 0. 4 s. The control system can identify 96% of the single dairy cow correctly. The feeding error was controlled at below 2% .%以计算机为信息管理平台,运用无线通信技术、射频识别技术及单片机等,设计了根据奶牛个体生理特征信息进行精确投料的控制系统.实现了奶牛精确饲喂技术中的智能识别、信息无线传输、双模行进及精确给料.该系统实现了奶牛养殖的自动化、精细化、智能化.实验表明:饲喂机的最佳行进速度为0.6 m/s,系统响应时间0.4s,识别率96％,计量误差小于2％.
