基于RFID技术的农产品质量追溯体系探讨

摘要

In view of the problems existing in agricultural products quality traceability system in China, based on analysing the technical framework of the RFID (Radio frenquency identification), several different data encryption methods were discussed and a RFID label containing product information and public key was designed by coding the data on RFID label and hashing the products quality information data. Finally, a quality track distributed model based on grid technologies was designed to resolve quality information tracing among different suppliers by grid services, and a method of quality information tracing from agricultural products processing to circulation links was described by an instance.%针对目前我国农产品质量追溯体系中存在的问题,分析了RFID(Radio frenquency identification)技术框架,讨论了几种不同的数据加密方法,通过编译RFID标签上的数据并进行哈希处理产品质量信息数据,设计了一种包含产品信息和公钥的RFID标签.最后,设计了一种基于网格技术的质量追踪分布式模型,该模型通过网格服务解决不同供应商之间的质量信息追踪问题,并通过一个实例来描述产品从加工到流通环节信息追溯的实现方法.
