摘要
提出了一种无线射频非接触式RFID学生考勤系统的设计方法。采用以射频卡U2270B器件为核心完成支撑电路设计,包括电源模块、频率模块、天线模块和数据输入;以及软件模块设计,主要模块有初始化、开启、停止和解码。目的是实现利用无线射频识别技术对学生进行考勤记录管理,从而达到考勤工作方便、快捷、省时。主要技术涵盖了射频卡读写器,和其关键器件射频卡基站器件。结果表明,该系统能快速实现各种考勤记录,提高了学校的教学管理效率。
The paper suggests a kind of design method of non-contact RFID student attendance system. The circuit design is carried out by taking chip of RF-ID U2270B as core,including power module, frequency module, antenna module and data input; and software module design of which modules are initialization ,start ,stop and decoding. The purpose is to achieve the management of students＇ attendance record by using wireless radio frequency indentify technology,which is very convenient, fast and time-saving. Its main technology is RF-ID reader and the key chip RF-ID base station chip. The result shows that the system can realize various attendance records and improve the teaching management efficiency of schools.
