Design and implementation of real-time traceability monitoring system for agricultural products supply chain under Internet of Things architecture

摘要

Agricultural products are an important guarantee for human health. The supply chain of agriculturalproducts as its carrier has always been a research hotspot in academia and business circles.Applying the Internet of Things andNFC technology to the agricultural product supply chain areawill play an important role in the intelligent management and traceability of agricultural productsupply chains. The intelligent management and traceability of agricultural products supply chainare the management of data information. How to collect, store, process, analyze, and visualizethe data information during the flow of agricultural products from the source to the table is animportant issuewhich needs urgent research. This paper proposes and validates theNFCtechnologyassumption of the application value of agricultural product supply chain. The communicationinterface between the agricultural product supply chain data acquisition terminal and the collectionterminalmodule and peripheral equipment based on BD, GSM, and NFCmodule is designed.The physical storage structure of the NFC tag is then planned, and the DES and RSA encryptionalgorithms of the NFC tag are implemented. According to the theory of Internet of Things, thetraceability 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 agriculturalproduct supply chain and uses the resources of the cooperative supply chain enterpriseto implement the system application and deployment. The experiment verifies that the real-timetraceability monitoring system for agricultural product supply chain proposed in this paper iseffective in practical application.
