1. Project background
According to data from the China Meat Association, in 2008, the national meat per capita was 54.8 kg, of which pork was 34.8 kg. Pork products accounted for more than 60% of the entire meat products. Pork hygiene and quality safety are directly related to the health of the people. And life safety. However, the current technical management level of the pig slaughtering industry in my country is backward, and the whole-process supervision system covering pig breeding, slaughtering, processing, circulation and consumption has not yet been formed, which poses a greater hidden danger to pork quality and safety. On June 1, 2009, the Food Safety Law was formally implemented, setting specific requirements for the production, processing, packaging, transportation, and sales of meat products. In order to ensure the effective implementation of the Food Safety Law and its implementation regulations, the Ministry of Commerce, together with the Ministry of Finance, has carried out pilot work on the construction of a service system of “Safe Meat” in 10 provinces and cities across the country, exploring and trying a variety of methods and experiences to ensure pork quality and safety , It will take 3 to 5 years to form a new mechanism for the healthy development of pig slaughter and meat circulation industries across the country.
In 2009, Premier Wen Jiabao expounded the new concept of “perceive China” IoT sensing technology during his inspection in Wuxi, marking that China’s “Internet of Things” has entered the actual construction stage. Therefore, the key technology of combining the RFID electronic tags of the Internet of Things and the intelligent network with the IC card is fully forward-looking in the application mode of the quality traceability system of pork products, and it can be adapted to today’s without framework adjustments within 3 to 5 years. The rapid development of China’s social economy and technology suits China’s national conditions. The use of RFID technology combined with network and information systems for data collection and communication can improve the efficiency of information collection and transmission, effectively identify meat products, and integrate scattered information, thereby solving the difficulties of the meat product traceability system , To achieve the entire information tracking and tracing need to achieve seamless links in all links in the supply chain.
2. Program objectives
Fuen’s raw pork quality information traceability system has established three major systems in accordance with the Ministry of Commerce’s “Reliable Meat” service system, namely the slaughter supervision support system, the meat quality safety traceability system, and the meat cold chain management system. Incorporate pig breeding, slaughtering and meat processing, transportation, wholesale, retail, etc. into the entire online supervision of the pork supply chain, so that the limited supervisory personnel of government departments can remotely manage any link that needs supervision no matter when and where. And supervision, real-time retrospective verification can be carried out for each link of the source of pork products to ensure that the accountability is accurate and timely in the event of food safety incidents, and the early warning and recall measures are effective and in place. For consumers, they can also be verified and compared when buying pork products.
3. System Architecture
Fuen Company has combined with the implementation of the Pork Product Safety Traceability System in Chengdu in 2009, and proposed “to guide technological innovation with government management model innovation, to transform traditional industries with high-tech, and to optimize supply chain business process optimization with high-efficiency and low-cost operation”. The solution provides a complete software and hardware solution for the three major systems in the “Safe Meat” service system-the slaughter supervision support system, the meat quality and safety traceability system, and the meat cold chain management system.
The raw pork quality information traceability system is for the management of pig farms, designated slaughterhouses, cold chain transportation links, meat wholesale markets, meat stalls in farmer’s markets, large supermarkets and hypermarkets, catering companies and designated units The quality and safety traceability system of live pigs and meat products. It uses the RFID electronic tags bound to live pigs and pork to associate with the different IC identity card information of various business users in the supply chain, and uploads the changes in the flow of pork in the supply chain to the central database in real time through wireless transmission technology, not only for each business user Log in to the platform system according to the authority to obtain daily business data stored in the government data center at any time, and various government business departments can also implement online supervision of all links in the supply chain according to their own jurisdictions, which provides a good way to ensure the safety of pork food. Technical support means.
In view of the characteristics of the safety supervision of raw pork products, the system is divided into two parts: the front-end data hardware collection end and the back-end data management software end. The front-end data collection is based on the core RFID technology for real-time monitoring of the relevant production site activities of fresh pork; the back-end data management is the use of government business systems to manage the real information reported in each link and the statistics and analysis of the front-end collected data , Distribution, etc., as shown in Figure 1.

4. Scheme operation process
From breeding to sales of raw pork products, there are mainly the following links: breeding, slaughter, wholesale or retail. This solution starts from the pig breeding link, through the real-time information binding of different forms of RFID pork tags and RFID identity cards of supply chain business personnel, and automatically links quality information and data upload to the downstream wholesale and retail links through mobile wireless communication technology. Download, to realize the forward tracking of related information from pig breeding to the meat retail terminal, and at the same time to realize the reverse traceability of the relevant information from the meat retail terminal to pig breeding.
Breeding link
Live pig breeding is divided into different stages such as breeding, pregnancy, waiting for birth, piglets, and commercial pigs. After piglets are released from the slaughter, RFID electronic ear tags will be worn, and the information of the piglets’ ancestors will be associated with the electronic ear tags. During the breeding process, the breeder will pass the RFID The handheld device writes the feed information, epidemic prevention information, medication information, and environmental information of sows, piglets, and finished pigs on the RFID electronic ear tags of pig ears, and uploads them to the food safety platform data center through wireless communication GPRS/3G, and Establish complete individual pig breeding files in the government data center.
Slaughter
When pigs arrive at the factory, they must first check the territory animal quarantine certificate or place of origin quarantine certificate, disinfection certificate, immunization card, and establish pig slaughter files, and then carry out pig slaughter and finished product inspection. Qualified pork white strips are bound with radio frequency identification traceability tags, and the pork code obtained by the radio frequency identification channel at the factory is automatically associated with the RFID identity card information of the downstream seller obtained by the RFID traceability integrated machine. At the same time, the all-in-one machine is also connected with the electronic scale to obtain the weight, and the all-in-one machine prints the meat product transaction voucher with the traceability system. The traceability code, weight, downstream buyers and other information of the batch of ex-factory meat products are uploaded to the government traceability supervision system at the same time. Each piece of pork corresponds to a unique merchant or operator, realizing the information link between pigs entering the factory and white strips leaving the factory during the slaughter process.
Wholesale link (slide trading system)
The pork with traceability information arrives at the wholesale market after transportation, and enters the sliding rail trading system for wholesale after going through the admission procedures and passing the inspection. In the sliding rail trading system, the UHF reader reads the traceability label of the pig white strips and automatically associates it with the sliding rail hook information read by the high frequency reader. After weighing, it associates the information of upstream and downstream operators and prints it. Transaction certificate. Downstream sellers, group buying units and individuals obtain wholesale market transaction vouchers at the live pig wholesale market. The transaction information of the suppliers and sellers that are transacted here enters the government data supervision center.
Retail link
Retail terminal-farmer’s market
It is sold at retail terminals such as farmers’ markets and convenience butchers. The special electronic scales equipped by farmers’ market operators have the function of reading RFID tags and processing traceable information. After reading the RFID tag data, each piece of cut pork is weighed. , Its printed sales receipts can be marked with the pork identification code, and at the same time, each weighing data is uploaded to the server of each farmer’s market management party, and then uploaded to the government data center in real time via the Internet.
Circulation terminal-supermarket hypermarkets, direct pork stores
The combined application of patented segmentation and traceability all-in-one machines, in-store traceability all-in-one machines, or MINI-type in-store traceability all-in-one machines in supermarket hypermarkets can easily connect with government data center information for filing, and at the same time transform RFID pork tags into low-cost two-dimensional Code stickers are provided to consumers as retail traceability certificates.
Pork direct-operated stores cut white strips of meat on-site and placed them on shelves for consumers to choose freely. The traceability integrated machine can read the pork label and print out the self-adhesive traceability certificate and provide it to consumers. Under the condition that the all-in-one machine has the Internet, the government supervision platform market management party and the slaughter enterprise monitoring center can check the sales status of each store in real time, which is convenient for enterprises to quickly replenish goods or adjust products in the same city in similar stores.
5. Traceability and supervision
During the transaction of raw pork products, the operator or final consumer will obtain the raw pork product traceability label, which includes the traceability code. Operators or consumers can enter the traceability code of raw pork products through self-service query terminals, the Internet, query telephones, text messages, etc., and perform quality information retrospective query, and then they can learn about the pork breeding site, slaughter processing site, inspection and quarantine information.
Under the three-level business management platform of provinces, cities, districts and counties that share a data center, staff of government departments such as commerce, agriculture committee, industry and commerce, quality inspection, health and other government departments can access the system through the Internet at any time according to their respective permissions to view the operating status of the entire process And related to the situation of pig products related to this department. Each market organizer under the jurisdiction of the industrial and commercial department is equipped with RFID inspection handsets to conduct inspections of pork entering the market, on-site inspection of RFID tags to read back-end data, and then compare the merchant’s meat transaction vouchers and “two chapters and one certificate”, etc. The paper-based procedures should be implemented in accordance with the requirements of the Ministry of Commerce to ensure that the three “single card certificates” go together to prevent pork that does not meet the standards from entering the circulation market.
