Application Research and Analysis of RFID Technology in Agriculture(2)

1.2 Application in animal identification and tracking

　　 Animal identification and tracking generally use specific tags to correspond to the animal to be identified by a certain technical means, and the relevant attributes of the animal can be tracked and managed at any time.

　　 Currently, a tracking system for cattle has been established in Europe. In September 1998, the United Kingdom announced a cattle tracking system plan. The British government stipulated that cattle born or imported after July 1, 2000 must be digitally identified. By the end of 1999, all EU member states implemented this system plan. From November 1, 2003, the United Kingdom began to implement new pig identification standards; from January 1, 2008, Europe will compulsory electronic identification of sheep; in addition, the British government also stipulated that from August 30, 2004 In the beginning, all horses must be identified and tracked.

　　The use of RFID in animal identification represents the highest level of current animal identification technology. Install an electronic tag on the animal, and write the

　　ID code. When an animal enters the recognition range of a human RFID fixed reader, or a staff member is holding a hand-held reader close to the animal, the reader will automatically recognize the animal's data information. If the data of the reader is transmitted to the animal management information system, the tracking of animals can be realized.

1.3 Application in agricultural and livestock production system

1.3.1 Tianwen servo system using RFID technology

　　The field servo system is mainly composed of field management monitoring equipment that uses RFID and other wireless technologies to automatically record field images and soil pH, temperature and humidity, sunshine, wind speed, rainfall and other micro-meteorology, and record the production growth records of agricultural products in detail. Among them, the Japanese field server (fjeld server) and the SW (S~, nsor Web) developed by the University of Berkeley in the United States and developed by MOTE and JPL are the most famous; in Taiwan, the Council of Agriculture promoted rice, tea and online marketing in 2005 Domestic fruit production and sales resume information and RFID promotion and application plan. It is planned to promote the development of organic rice, tea and online marketing of domestic fruits as a demonstration system for the electronic management of agricultural resources and environmental management, which involves the use of field servo systems for the production of fine agricultural products. In mainland China, Professor Wang Maohua from China Agricultural University, Professor Wang Ning from McGill University in Canada, and Professor Zhang Naiqian from Kansas State University in the United States have also conducted in-depth research on this. Generally speaking, this fine production model of agricultural products is still in a small-scale experimental stage and has not yet been widely applied.

1.3.2 Digital system for fine breeding of livestock products using RFID technology

　　 In 2003, it was included in the 863 digital agriculture project of my country for the first time in the research topic of digital breeding. At present, a set of RFID cattle individual identification system based on long-distance system has entered the practical stage. The system uses a collar-type transponder, hung on the neck of the cow. When the cow passes the system's automatic weighing cart, the reader in the system will automatically read the cow's unique number and complete the weighing process through the pressure sensor. The two one-to-one corresponding data (number one weight) together with the collection time are sent to the upper server of the farm through the wireless local area network, which provides important real-time data for the digital farming platform. Digital precision breeding is an important technical means to improve the intensification of animal husbandry and improve efficiency. In the precision breeding digital system, RFID and other sensor technologies are used to track the physiology and production activities of captive livestock, and through wired or wireless communication connections, a computer data control center forms a distributed computer management network. The system function adopts modular design to support the expansion and integration of business areas such as warehousing, logistics and distribution, operation and management. It is a useful attempt to modernize the development of animal husbandry.
