my country is a large agricultural country, and agricultural and livestock products have an important position in the circulation of domestic and foreign markets. The application of RFID technology in the animal food safety traceability system will ensure the exchange of high-quality food information and data in all aspects of food production, processing, circulation, etc., and completely realize the "source" tracking of food and provide transparency in food safety. Management provides technical support, which greatly improves the quality management capabilities, logistics management capabilities and competitiveness of international trade in livestock products. It is also conducive to standardizing and purifying the livestock product market.
Strengthening the supervision and management of animal food safety and solving the problems in animal food safety as soon as possible has become a very urgent task at present. At present, all animal husbandry farms are looking for and adopting various means to strengthen the identification and tracking management of animals in order to improve the value of their products and market competitiveness.
The importance of RFID traceability
The application of the animal food safety traceability system in animal food safety control includes not only the recording and monitoring of the entire feeding process (feeding management, feed use) of animals from birth to entering the slaughterhouse, but also the entry of animal products into the consumer market (supermarkets, etc.) ), consumers can use the unique identification code of each animal to inquire about the whole feeding, slaughtering, processing and circulation process of the animal product.
The implementation of animal food safety traceability system is conducive to the safety and health guarantee of animal product quality. On the one hand, it can ensure that any designated target with potential quality and safety hazards withdraws from the market, facilitating the implementation of a "recall system" for harmful food. At the same time, the behaviors of livestock product manufacturing enterprises are also prevented to prevent the enterprises from deliberately concealing behaviors, and the enterprises are urged to take early measures to minimize the damage caused by defective products to the safety of the people. On the other hand, it can also provide information to consumers and related organizations to avoid the expansion of chaos in a timely manner.
Composition of animal food safety traceability system
1. Hardware Composition
According to the characteristics of the animal breeding process, active RFID tags are selected, so that the recognition distance can reach 50 m, and the data can be quickly read through the matching reader in the breeding area. There is no need for animals to be concentrated in a dedicated identification channel, which can reduce the stress response of animals caused by driving.
In the animal food safety traceability system, RFID tags and readers transmit data through the antenna magnetic field, according to the actual application needs of the farm. For example, the feed sensor of the automatic feeding system can transfer the animal feeding data to the computer. After the data in the computer is modulated and demodulated, the communication method with the network data center can be GSM, DDN, or PSDN. Realize data transmission and linking functions.
2. Software composition
To ensure high-quality food safety information exchange, thoroughly realize 100% tracking and complete transparency in the production, processing and circulation of food. Combined with the whole process of animals from birth, breeding, slaughter to sale.
(1) Farm farm data center
Animal feeding is the longest link in the entire production process. The files related to the identity of livestock include livestock identity identification codes, entry and exit dates, and farmer information. According to the analysis, the feed and immunization situation are mainly recorded and monitored during the breeding stage.
(2) Network data center of slaughterhouse
The slaughtering stage is the most complicated link in the whole production process, with short time and many links. The information of this link should be connected with the data of the farm network center, plus slaughter records: slaughterhouse information, time to enter and exit the slaughterhouse, quarantine certification information, and the name of the relevant quarantine personnel. According to the analysis, the slaughtering stage mainly monitors the transportation of pigs, quarantine of pigs, pork inspection, slaughtering environment, and the transportation of pork, and early warning of violations.
(3) Meat processing plant network data center
This part is mainly based on the network data of the farm and slaughterhouse, adding relevant information such as the information of the processing plant, the time to enter and exit the processing plant, and the product shelf life.
(4) Logistics and distribution network data center
This part is mainly for querying historical records, not too much information needs to be recorded. The key is the connection with other network data centers and the corresponding relationship between information conversion. For example: the conversion relationship between barcode and label information.
The data of these 4 network data centers are finally linked and managed through a total database. Different network data centers can carry out linking and querying of relevant data through livestock identification code.
The whole system uses multi-thread technology, which can realize the detection of the use status of RFID tag readers in the farm.
