摘要
Agricultural products safety has become an important global public-health issue. With the exposure and the emergence of some agricultural products' quality and safety issues in China, safety issues for the quality of agricultural products has become the bottleneck of the sustainable development of agricultural and agricultural products for import and export trade. In response to the risk in the agricultural products supply chain and to improve services, the traceable platform of the agricultural products supply chain is highly required. Quality problems of agricultural products could occur in every aspect of the agricultural products supply chain, including breeding, processing, distribution, and sale. So not only policies, but also technical supports are needed to ensure the quality and safety of agricultural products and to bottom out the safety hazards. In response to these issues, this paper took broiler as the object of study and designed and developed a information system platform of the agricultural products supply chain based on near field communication (NFC) and internet of things. The integration applications of NFC technology and internet of things have become a focus research issues at home and abroad. In this paper, we reviewed supply chain information systems research progress of domestic agricultural products, summarized the key function of information technology in the agricultural supply chain and information systems platform, and analyzed the application feasibility of NFC technology in the agricultural supply chain information systems. In this paper, we designed chicken supply chain information system framework based on the integration applications of NFC and internet of things, and designed hierarchical, data structure, information processing of information system. This information systems platform has the following characteristics:1) It had a monitoring function of broiler farming, and can track and trace all aspects of information from breeding, production, processing, and distribution to sale; 2) It bringed out informationization on the production and management of enterprises, and achieved all-the-way monitoring of broiler's quality and safety through the construction of information technology; 3) It had three functions including feed and culture environment etc monitoring, early warning of broiler's epidemic, and early warning of the risks of broiler's quality and safety, which facilitated enterprise management and supervision of broiler's quality for quality supervision departments; 4) Consumers can inquire and complain about broiler product information with the NFC-enabled mobile phone or device; 5) NFC technology can read and write agricultural production, distribution and sale data automatically and can record and store all product information, which completely solve the problem of information distortion of traditional RFID technology; 6) NFC technology can solve the poor security problems of traditional RFID tag. NFC tags required to write data in every aspect of production and circulation, every vendor had the permissions of modify the corresponding sectors only, and prohibited the manufacturers modify data writing by time constraints. When writing data, vendors used geographic information encryption, scrolling encryption, RSA or EDS, and ensured the integrity and authenticity of data. The results showed that the supply chain information system based on the application of NFC technology enabled the broiler supply chain information full record, ensured the safety of each node information of broiler supply chain, improved the efficiency of broiler supply chain, and provided trace and recall examples for other agricultural products.
