RFID technology is an emerging high-tech automatic identification technology in the 1980s, and is listed as one of the top ten important technology projects in the new century by high-tech related departments. But it wasn't until the 1980s that only the technology and its derivatives could truly enter the commercial arena. Since the 1990s, the issue of RFID technology standards has been paid more and more attention, the theory of RFID technology has been further improved, and RFID technology derivatives have been widely used, and gradually entered the medical, real estate, transportation, telecommunications, finance, ID cards and other related fields.
In recent years, China has started to raise pigs on a large scale. At the same time, the occurrence of pig diseases, especially swine fever, has become an obstacle that seriously affects the scale of my country's pig industry. The "Measures for the Management of Livestock and Poultry Labeling and Breeding Archives" adopted at the 14th executive meeting of the Ministry of Agriculture came into effect on July 1, 2006, hereinafter referred to as "the Measures". The introduction of these measures is of great significance for further regulating the production and operation of animal husbandry and strengthening the quality and safety of livestock and poultry products. The management stipulates that the livestock and poultry identification implement a livestock and poultry identification, and the code is unique. Therefore, the identification and coding of livestock and poultry is a complex system engineering and must be placed in a key position. This is for RFID to be seen, the emergence of technology is a need for RFID technology development prospects are quite broad.
The working principle of RFID technology
After the tag enters the magnetic field, if it receives a special radio frequency signal from the reader, the product information stored in the chip (ie PassiveTag, passive tag or passive tag), or actively sends a signal of a certain frequency (ie ActiveTag, active tag) or active tag), the reader reads and decodes the information, and sends it to the central information system for related data processing.
The application of RFID animal identification technology
The so-called animal identification is to install electronic tags on animals, and one-to-one with animals according to the different ID codes of animal electronic tags, animals can be tracked and managed anytime and anywhere.
How to use: When the animal enters the identification range of the RFID handheld terminal, or when the breeder approaches the animal with the handheld terminal reader, the reader will automatically identify the relevant information of the animal.
According to the relevant regulations of international standards ISO11784 and ISO11785, animals use RFID identification code structure and standards. ISO11784 specifies that the animal identification code consists of a total of 64 bits (8 bytes). ISO11785 specifies the transmission method of electronic tag data and the specification of the reader.
The installation method of animal electronic tags: strong item type, ear tag type, injectable type and pill type electronic tag.
The application of RFID technology in pig industry
According to China's national conditions, under the funding of 15 national 863 programs, Lu Changhua of Jiangsu Agricultural University and others have comprehensively applied animal individual identification, two-dimensional code, RFID electronic electronic identification and one-dimensional barcode label technology to combine network technology and database technology with traditional pig raising. The combination of industry and slaughtering and processing has built a pork monitoring and traceability system suitable for China's national conditions.
With the continuous development of China's economy and the continuous improvement of people's living standards, the requirements for the quality of life are also increasing. Of course, the requirements for pork quality are also increasing. Using computer technology, pig enterprises can make the management of pig enterprises more scientific and accurate, and create higher benefits in the process of large-scale management.
In summary, the extensive technical application of RFID technology has brought objective benefits to enterprises, and the development of RFID technology in the future is also unlimited.
