基于射频技术的奶牛身份识别系统

针对当前奶业所存在的养殖规模较小、单产水平低、管理技术落后、饲料单一、牛群血缘不清，以及由此导致动物产品安全无法得到有效的保证的问题，提出并建立了一种基于无线射频识别技术的奶牛的身份识别系统。该系统通过采用瘤胃式动物电子标识来为每头奶牛建立一个永久性的数码档案，实行一畜一标，并通过采用RFID技术以及单片机与PC机的通信技术对存储奶牛信息的电子标签进行远距离识别，从而及时的实现对每头奶牛的监控与管理。研究结果表明RFID系统读卡器的识读率为100%，识读距离可达到8 m以上。该方法不仅实现了对奶牛生产养殖的数字化管理，也为精细养牛提供了理论依据。

Cow identification technology system based on radio frequency

In view of the existing problem in China including dairy farm at small scale, low level of production, backward management of technology, single feed, unclear cattle blood type, and animal product without effective guarantee of safety, a dairy cattle identification system was proposed and established, which was based on the radio frequency identification technology. The rumen animal electron blip was adopted to build a permanent digital file of milk cow in this system and each livestock was labeled with one corresponding file. The cow information stored in electronic tags was identified by RFID technology and PC-SCM technology to make each cow under timely monitoring and management. The results show that the reading rate of RFID system was 100% and the reading distance of which can reach more than eight meters. Therefore it is feasible to apply RFID technology in distinguishing the identity of the cow. This method not only makes the dairy farming production under the digital management but also provides a theoretical basis for precision cattle breeding.
