摘要
RFID(无线射频识别)是一种自动的无线数据采集技术,随着集成电路和无线电技术的发展,RFID技术得到了巨大而又显著的进步。近年来,超高频(Ultra High Frequency UHF)射频识别统在物流管理领域的应用中日益受到关注,因此对UHF RFID系统的研究和改进具有重要的意义。本文首先介绍了ISO/IEC18000-6标准中A、B、C三类标准,分析了脉冲间隔编码(PIE)方式的基本原理及PIE编码的信号特征。然后,文章以虚拟仪器技术为基础,在Lab VIEW软件平台上对PIE编码方式进行了编码设计。本设计既可以应用于RFID测试系统,也可为商业RFID阅读器的设计提供参考。
RFID (Radio-frequency Identification) is an automatic wireless data-collection technology, and RFID has significantly advanced and experienced a tremendous growth due to developments in integrated circuits and radios. Recently, there are increased interesting in UHF RFID from many fields,such as logidtics, commerce and trade and so on, therefore,it's of great significance to the research and improvement of UHF RFID system. The first , the peper investigates data encoding methods according to types A,B and C in ISO/IEC 18000-6,introduces the fundamental principles of PIE and analyses the characteristic of PIE coding specially.The second, based on the virtual instrument technology as the foundation, we designed the code method of PIE coding on LabVIEW. This design can not only be applied to the RFID testing system, but also provide the reference for commercial RFID reader.
