【摘要】 随着社会经济和科技的发展，射频卡技术越来越广泛地应用于各种行业，特别是公共交通、无线通信、身份识别、金融交易和安全防卫等行业。 过去，智能卡应用领域常采用磁卡或接触式IC卡，但由于读写速度慢，易磨损，使用寿命短，无法保证系统长期运行的可靠性和方便性。射频卡技术的出现弥补了这些不足，射频卡是无接触式IC卡，读写速度快，功耗低。本文将介绍射频卡技术在安全防卫领域内的应用。 本文首先简单介绍了智能卡的发展历史及未来发展方向，讨论不同智能卡的技术特点和应用方向，重点对射频技术和射频卡进行介绍；然后详细讲述系统硬件和系统软件设计及开发过程，对硬件电路功能构造、硬件电路采用的芯片、硬件驱动程序的编写、串口通讯程序编写、数据库系统构造和多进程多线程设计的实现及应用界面接口等作了具体详细的介绍；在介绍完系统硬件和软件设计后，给出系统的操作界面和部分运行结果；最后对本项目进行总结和展望，给出项目还需要改进的地方。更多还原

【Abstract】 With the development of social economy and science technology, RF ( Radio Frequency ) card technology is more broadly applied by all kinds of trades, specially such as mass transit , wireless communication identify finance trade and safety-defend etcWe use usually magnetic card or touch IC(Intelligent Card) in the past, but the shortage is that the card is read-write low efficiency frictional waste and short life, so that it can’t guarantee the reliability of system for long term running. RF card is a kind of untouch IC card. RF card will make up for those shortage of magnetic card or touch IC card. It is read-write faster and more efficiency than them. This paper will discusses the use of RF card technology in the safety-defend system.Firstly the paper introduces the former development history and the future development direction about IC, then discusses the technology speciality and the application direction for all kinds of IC. Secondly, the paper discourse the design & development process of the system hardware and system software in detail, including design of hardware circuit, introduce of the hardware circuit chip, program of the hardware driver, program of the serial communication, design of the multi-process & multi-thread program, database system construction, interface of system software etc.. After the finishing of the as-above part, the paper give the interface &result of the system running. Finally the paper summarizes the research course and advances the prospect of project, then point out the point that need improve.更多还原
