随着改革开放的深入和市场经济体制的不断完善，传统的人工收费方式己越来越不适应现代化管理的需要。随着电子技术和通信技术的发展，公交系统与IC卡技术相结合成为发展的必然要求,使公交汽车自动收费的实现从技术上成为可能。本文以非接触式IC卡读写器为设计对象，研究了系统的总体结构。以8051单片机为核心，根据公交IC卡控制系统的性能指标，采用无线射频技术，运用一套合理的安全管理策略，完成公交非接触式IC卡控制系统读写器的硬件设计及软件设计。并开展了对非接触式IC卡控制系统的安全性研究，在本文最后重点论述了系统中心管理的分析与设计。
关健词: 读写器；非接触式IC卡；系统安全；中心管理

Abstract
With the deepening reform and opening up,traditional combination of public traffic charging system use manual-observed combination of public traffic monitoring system is not suit for the requirement.With the development of electronic technology and communication technology,the combination of public traffic system and IC card technology becomes inevitable request for development.Various automatic meter charging systems have emerged as the times require.The says as designed object is for the RF reader of the contact-less IC card,according to the design needs of the controlling system which is owned for public traffic IC card,the overall technical blue print is studied.It used 8051 as the core,adopted RFID technology and some information security strategies.Then the hardware and software design of the RF interface coprocessor has been finished.However,The research on the information security of the design has been done.This paper puts emphasis on the analysis and design of system center administration.
Keywords: RF Reader and Writer; Contact-less IC Card; System Security;
