摘　　要：介绍了一款应用于门禁管理系统中的基于TRF7960射频芯片和STC12C5410AD单片机的多协议自适应功能的射频读卡器,重点阐述了该射频读卡器的系统结构、各个模块的功能、系统的特点以及相关软件设计和工作流程。本系统主要由单片机控制模块、显示模块、信息接收模块和上位机组成。信息接收模块包括射频模块和按键模块,共同完成信息的接收与传送;显示模块主要显示控制模块对接收的信息进行处理后的内容;上位机主要用以存储有效信息供系统识别和查询。The paper introduces a radio frequency reader used in access control management based on the radio frequency chip TRF7960 and single-chip microcomputer STC12C5410A,which enjoys multi-protocol and adaptive functions. It focuses on the structure of the RF reader systems, function of each module, characteristics of the system, and related software design and workflow. The system consists of SCM control module, displaying module and information receiver module. Information receiver module, along with RF module and key module completes the receiving and transmitting of the information. Displaying module shows the received information that is processed in the control module.
