摘要
Agricultural products are an important guarantee for human health. The supply chain of agricultural products as its carrier has always been a research hotspot in academia and business circles. Applying the Internet of Things and NFC technology to the agricultural product supply chain area will play an important role in the intelligent management and traceability of agricultural product supply chains. The intelligent management and traceability of agricultural products supply chain are the management of data information. How to collect, store, process, analyze, and visualize the data information during the flow of agricultural products from the source to the table is an important issue which needs urgent research. This paper proposes and validates the NFC technology assumption of the application value of agricultural product supply chain. The communication interface between the agricultural product supply chain data acquisition terminal and the collection terminal module and peripheral equipment based on BD, GSM, and NFC module is designed. The physical storage structure of the NFC tag is then planned, and the DES and RSA encryption algorithms of the NFC tag are implemented. According to the theory of Internet of Things, the traceability system of agricultural product supply chain is divided into four levels: physical layer, service layer, data layer, and application layer. The three major areas of enterprise management, user query, and government supervision are designed to trace the information flow and system. Finally, this paper analyzes the hardware resources needed for the traceability system of agricultural product supply chain and uses the resources of the cooperative supply chain enterprise to implement the system application and deployment. The experiment verifies that the real-time traceability monitoring system for agricultural product supply chain proposed in this paper is effective in practical application.
