This system uses RFID high-frequency technology as the core food (meat, vegetables, etc.) quality and safety traceability information management mode, realizes information application services with RFID as the key index, and provides exemplary applications of food (meat, vegetables, etc.) It is fully involved in the collection, recording and exchange of information in the planting (breeding), distribution, logistics, product inspection, wholesale, market sales, etc. of the food (meat, vegetables, etc.) supply chain, and for different objects involving food (meat, vegetables) Etc.) provides a solid foundation for quality and safety application services.
The system adopts the mode of combining C/S+B/S. The municipal management platform and each business subsystem adopts the B/S model, the municipal management platform assigns accounts uniformly, and the wholesale market electronic settlement system adopts the C/S model. At the same time, the electronic scale data collection in the retail market also adopts the C/S mode. The market inspection handset is connected to the municipal management platform through the GPRS network. The electronic scale with GPRS transmission network is also directly connected to the municipal management platform. The platform architecture is A hierarchical, component-oriented and service-oriented software architecture based on J2EE and .net platforms. Take the traceability of fresh meat as an example:
Figure 2: Schematic diagram of RFID fresh meat traceability principle
All food safety-related information of fresh meat products from the feeding link to the slaughter link to the sales link is collected and stored in the server through RFID technology, and is provided to the government supervision department for joint supervision and consumer traceability of the fresh meat food safety. Inquirers can connect to the internet/GPRS/3G network through a variety of fixed terminals and mobile terminals to conduct inquiry and authentication for each link.
