1. System introduction
In recent years, food safety (food poisoning, mad cow disease, foot-and-mouth disease, bird flu and other livestock and poultry diseases, serious agricultural residues, and a surge in imported food materials, etc.) have occurred frequently, which has seriously affected people’s health and caused widespread worldwide Paying attention to how to effectively track and trace food has become an extremely urgent global issue.
At present, the output of major foods such as cereals, fruits, meat, poultry, eggs, and aquatic products in my country ranks first in the world. In order to ensure the food safety of the people, effectively control the outbreak of food-borne diseases, and eliminate the export of my country’s food products. Food tracking and tracing laws and regulations of importing countries are regulated, so the establishment of food tracking and tracing work in my country will have a huge impact on the development of the food industry. However, there are still very few examples of the application of the automatic traceability system in the entire food production process in my country. The traceability of the domestic food industry is currently mainly only in the retail settlement link, and is far from being applied in the entire food supply chain. The entire supply chain can be traced. form.
Xindao Technology’s RFID food traceability management system will use advanced RFID technology and rely on network technology and database technology to realize information integration, query, and monitoring, and provide specific products for each production stage and the process of distribution to the final consumption field. Reasonable decision-making on safety, food ingredient sources and inventory control, realizing food safety early warning mechanism. RFID technology runs through food safety, including production, processing, circulation, and consumption. The whole process is strictly controlled, and a complete food safety control system of the industrial chain has been established, forming a closed-loop production for the production and sales of various food companies to ensure Provide the society with high-quality and assured food, and ensure high-quality data exchange in the supply chain, allowing the food industry to thoroughly implement the source of food traceability and the ability to provide complete transparency in the food supply chain.
Through the construction of this system, the problem of inaccurate reading of data due to the damage to the bar code caused by oil pollution, humidity and other reasons is solved. It can not only trace the disease and pollution problems in the breeding and processing industry, but also trace the abuse of drugs during the breeding process. , The use of additives beyond the scope and limit in the processing process has changed the previous food quality and safety management that only focused on post-production control, while ignoring the phenomenon of production prevention and control. Improved food processing technical regulations, hygienic specifications and certification standards in production, and promoted the industry’s The overall progress will comprehensively improve the level of my country’s food industry.
2. System structure
Xindao Technology’s RFID (electronic label, radio frequency identification) food traceability management system can ensure food safety and can be traced throughout the process. It regulates the four links of food production, processing, circulation and consumption, and integrates food such as rice, flour, oil, meat, and dairy products. All issued an “electronic ***”—all are affixed with RFID electronic tags, and a food safety database is established, starting from the food planting and breeding and production and processing links, to achieve the tracking and tracking of the whole process from farmland to table Traceability, including all the information in the circulation process of transportation, packaging, sub-packaging, sales, etc., such as production bases, processing companies, distribution companies, etc. can be found in the database through electronic tags.
Food traceability management system includes:
Three levels of structure: network resource system, public service system and application service system
Secondary node: It is composed of the food supply chain and safety production supervision data center and the key monitoring nodes in the food industry chain. The data center provides sufficient storage space for massive food traceability and safety monitoring data, ensuring the openness, resource sharing and safety of information sharing, and realizing food tracking and safety monitoring management functions. The key monitoring nodes include planting and breeding nodes, production and processing line nodes, warehousing and distribution nodes, and consumption nodes, which realize the connection of data collection and information chain of each node, and make each link visible.
A data center and infrastructure platform: 1 center is the food supply chain and safety production supervision data management center. This center is a management platform built on the basic support platform of JieXun Electronics ezRFID (Figure 5). EzRFID is RFID middleware and the center of RFID operation. It acts as an intermediary between hardware and applications. It will realize the smooth operation of various RFID devices and software at different nodes and different traceability links. The functions included are not only the delivery of information, but also services such as interpretation of data, security, data broadcasting, error recovery, locating network resources, finding a cost-compliant path, and prioritizing messages and requirements. Its function is mainly reflected in two aspects. One is to operate and control the RFID read-write device to work in a predetermined way to ensure coordination and coordination between different read-write devices; the other is to filter data according to certain rules to filter out most of the redundancy. Data, the truly effective data is transmitted to the background information system. The framework includes two parts: RFID edgeware and RFID integrated middleware.
The following is a schematic flow diagram of the tracking system for livestock (Figure 6), grains, oils, and vegetables (Figure 7).
As shown in the figure, after the pig or cow is born, it is marked with an RFID electronic ear tag. The ear tag contains the unique identification number of the pig or cow. This number will run through all nodes and be associated with the relevant management and monitoring information of each link , In order to achieve the retrospective purpose.
