摘要
近几年方兴未艾的物联网,是通过赋予物品唯一可区别的产品电子编码(EPC),可借助射频识别技术(RFID)收集数据,以互联网为平台,实现数据在供应链之间的互换和共享,从而大大减轻传统供应链中信息不对称和高成本的问题;文中从宏观结构的角度,先分析了EPC网络的结构模型,然后主要介绍Savant结构及其中间件技术、域名服务系统及其工作流程和物理标记语言(PML)技术的组成和设计,最后对物联网的未来发展以及主要所面临的挑战作了简要的评述和展望。
The Internet of Things, on the base of radio frequency identification （RFID） technology, remarkably reduced the cost of rational business supply chain by the way of encoding the world widely using unique electronic product code （EPC） and sharing and exchanging information on the Internet. This article makes analysis of the EPC system about the structural model from a macro point of view, and introduces some key technologies, such as the structure of Savant system and the system of Object Naming service and its workflow, the frame and design of physical marking language （PML）. In the end, the comments and future of the Internet of Things are given.
