摘　　要：提高IC卡读卡器的性价比是使其具有市场竞争实力的一个重要环节。本文以射频识别技术为基础,设计了基于P89C669的RFID读卡器系统。主CPU采用P89C669单片机,利用它的双串口,实现读卡器与双操作台通信。文中首先介绍RFID系统的组成及RC500的特性,接着给出由P89C669单片机和RC500构建成读卡器的原理设计,以及系统软件流程。应用表明,该RFID系统达到相应的技术指标,具有良好的应用前景。Improving the quality and price ratio of IC card reader is an important part for making it more market competitive. A Radio Frequency Identification reader system was designed, which is based on P89C669 chip in this paper. By using P89C669 ’s dual serial ports,it is communicated with two Operating Control Panel. Firstly,the RFID based on P89C669 and RC500 features are introduced, then the design of card reader based on P89C669 and RC500 is presented. Finally, the flow chart working between card reader and card based on P89C669 chip was also given. Application shows that the RFID system has achieved the corresponding technical index. It has a good application prospect.
