基于射频识别技术(RFID)的汽车防盗系统开发设计

Design of Car Alarm System Based on Radio Frequency Identification Technology

摘要:

作为热门的电子产品之一,射频识别装置受到市场的追捧,射频电子技术的市场潜力非常巨大,论文将射频识别技术(Radio Frequency Identification Technology)应用在汽车防盗系统中,文中提出的射频识别装置由两部分组成,分别是汽车启动顶部的应答器和内部的阅读器构成,对整个装置的硬件和软件系统进行设计开发,首先搭建硬件系统的整体框架进行,重点对射频卡读写电路进行设计,包含射频电源和外围元件的选择以及射频电路的设计,软件系统设计方面,重点研究了读卡和写卡软件设计,给出了相应的时序图和程序流程图,达到了射频程序可靠读写的目的；结论表明,射频识别装置避免了市场上使用电池遥控装置,有效地实现了汽车防盗的目的。

Abstract:

RFID system is one of the market's most popular electronic products, radio frequency technology industry has good prospects for the industry. This paper carried a radio frequency identification technology (RFIT) in automobile anti-theft device research, radio frequency identification device proposed consists of two parts, namely, the transponder and the internal reader constitute the entire device hardware and software design and development, the first to build a hardware system's overall framework, focusing on RF card reader circuit design, including design choices and RF power RF circuits and peripheral components, software system design, focuses on reading cards and write card software design, and the corresponding timing diagram and flowchart program make the radio program reliable reading and writing purposes. It means this paper avoids the use of battery remote control device on the market, effectively achieve the purpose of anti-theft of car.
