电子产品代码网络研究

Research on Electronic Product Code Network

与传统条形码识别技术相比,射频识别(Radio Frequency Identification,RFID)具有扫描速度快、体积小、易封装、可抵抗污染、可重复使用、穿透性强、存储容量大、安全性高等优势,其应用将给零售、物流等产业带来革命性变化。本文介绍了EPCglobal组织的RFID体系框架和标准化现状,阐明了电子产品代码(Electronic Product Code,EPC)网络的组成,分析了EPC编码标准、EPC标签、读写器、Savant系统、对象名解析系统(Object Numbering System,ONS)、物理标识语言的基本结构和功能原理,最后给出了EPC网络的工作流程。

Compared with bar code, Radio Frequency Identification （RFID） tag has high scanning rate, small volume, and resistance to dirtiness, reusability, good penetrability, and high security. Its application leads to revolutionary transformation in retail and material flow field. This paper introduces RFID architecture and related standards of EPCglobal, and then set forth the architecture of Electronic Product Code（EPC） system, analyzes the basic structure, functions and prineipium of the related components, i.e. EPC encoding standard, EPC tag, reader, Savant, Object Numbering System （ONS）, Physical Markup Language （PML）. Finally, the working flow of EPC system is presented.
