With the development of Internet of Things, Radio Frequency Identification (RFID) is widely used in retail, food traceability, transportation, transportation of dangerous goods, medical and health, smart grid, storage management and library management. RFID application deployment environment in various industries vary widely, and the wireless environment is more complex, which has brought great challenges to the on-site deployment and debugging of UHF RFID system. This paper mainly focuses on UHF RFID system which is based on ISO18000-63 standard (changed from ISO18000-6C), describes the basic working principle, the basic structure of the system and characteristics of UHF RFID system, and proposes the methods to optimize and improve the system stability and performance by combining with UHF RFID system project.%随着物联网的发展,射频识别RFID技术在零售、食品溯源、交通运输、危险品运输、医疗卫生、智能电网、仓储管理、图书管理等领域的应用越来越广泛.各个行业的RFID的应用部署环境千差万别,无线的环境比较复杂,对超高频RFID系统的现场部署和调试带来了极大的挑战.本文主要围绕超高频RFID系统,它基于ISO18000-63标准(ISO18000-6C更改而来);阐述了超高频RFID系统的基本工作原理,系统的基本结构及其特点,结合超高频RFID系统项目,提出优化和改善系统稳定性、提高系统性能的方法.
