摘要
针对射频卡的读写系统,采用STC89S52为主控芯片,研究了MF-RC500的射频卡读写系统设计方法,通过RS232为数据传输接口连接上位机以及键盘来构建一种适用于各个应用场合的非接触式IC卡读写系统,程序中利用单片机的低功耗模式达到系统节能降耗的目的。实验表明,基于MF-RC500射频卡读写系统设计运行稳定,切实可行。
TO radio frequency(RF) card read-write system,the main control chip of STC89S52 is adopted and the design method of RF card read-write system based on MF-RC500 is researched. Through RS232 interface for data transmission to connect PC and keyboard,a kind of non- contact IC card read- write system adapting to the various applications is built,using low power mode of microcontroller to achieve the purpose of system energy saving. Experiments show that the RF card reader based on MF-RC500 system running well, is feasible.
