Cow Based On Radio Frequency Identification Technology System

Dairy industry is an important component and embranchment industry in stockbreeding and agricultural field, and it's plays an important role in the national economic and social development. But global mad cow disease, foot and mouth disease and other infectious diseases cause great impact in the dairy industry of our country. Except for the prevention of these diseases, modern management of the cow is also a essential means for the treatment of these diseases, especially for dairy cows for traceability management. Because of the modern large-scale dairy farming, the traditional identification and recognition of artificial job is difficult, inefficient, and heavy workload, and often can not meet the requirements of efficient management, therefore non-contact characteristics of the rapid identification of RFID technology has become the best choice in current traceability system. In this study, on the basis of substantial literature available, and aimed at the characterization of dairy farming in our country, such as the existence of smaller, low yield, management, backward technology, feed a single, clear the blood of cattle, and the safety of animal products cause our country can not be effective guarantees, we put forward and set up a cow's identity recognition systems based on the radio frequency identification technology. The system can construct permanent digital files for each cow through the use of ear mark-type, and identification the stored electronic tag of cow information through the use of RFID technology, as well as PC-MCU and communication technologies, thereby monitoring and management each of the cow timely.This article introduced the composition and classification of the radio frequency identification system, and then analyzed and discussed the hardware systems and the key to the overall structure of the circuit design in detail, designed UHF band RF identification system based on ISO/IEC18000-6 Type B protocol. And then discussed the RFID technology based identification system, and explore the 100 experiments cow with electron wearing and the implementation of chip-based precise feeding management system, and their distance of the reading, error ratio of the read-write and against conflict read electronic tag's quantity were statistically analyzed. At the same time, wireless radio frequency identification system were installed and debuged. The results showed that the reader's identification rate of RFID system is 100 percent, reading distance is up to 8 meters. This method achieved Digital Management of the dairy productione, as well as provides etheoretical basis for fine breeding. In hardware design, ATmega32 of single-chip microcomputer was selected as a main controller to constitute the main control, keying reset, serial communications, instructions and other circuit devices. And RF transceiver was designed by use of TR1000 RF transceiver chip developed by RFM.In the software part, ideas of modular programming and structured programming were applied, and C language were selected as the programming language. The whole work flow and its key technologies: anti-collision method, were described ordinal.The whole issue of the article was summed up finally, and worthy of further study and optimization of the part were put forward, then prospect the topics.
