摘要
在研究射频智能卡与其读写器工作原理的基础上,选用 TI 公司提供的射频芯片 RI-R6C001A 设计了读写器射频接口电路,设计开发了与 PC 机进行数据通信的读写器 RS-485通信接口。编写读写器端通信软件和 PC 机端通信软件,实现了 PC 机将管理信息、应用数据等下载到读写器和读写器将相关记录信息、上传至电切换电路、全桥逆变电路和 RCD 缓冲电路、串联辅助谐振电感和电容、电源侧电流互感 PC 机的功能。
This paper researches the realization of personal medical treatment information system based on RFID. Based on the analysis of the operation principle of the inductance coupling radio frequency intelligent card and its reader/writer, radio frequency interface circuit is designed by using RI-R6C001A chip. Communication interfaces, including RS-485, with PC computer are designed. The communica- tion software is implemented both on card reader/writer and on PC computer. The data such as management information, application data, etc can be transmitted from PC computer to card reader/writer, and some relevant records from card reader/writer to PC computer.
