基于轮询机制的RFID读卡系统的设计与实现

摘要

设计基于轮询机制,分别从4台RFID读卡器获取主动式RFID标签的数据.采用Visual Studio C++6.0开发语言和MS SQL Server 2005数据库,通过WINDOWS API和CSerialPort类库实现COM端口与RFID读卡器、RFID卡配置器和身份证阅读器之间的通信,并通过RFID读卡器数据记录与RFID卡配置模块的数据记录进行匹配,实时获取人员所在位置,实现人员的定位和管理.应用效果表明,RFID读卡系统能快速稳定地完成数据采集与更新,解决景区景点相隔较远的人员定位和管理问题.%Based on polling mechanism, the design of the RFID reader system gets the data of active RFID cards from four RFID readers, respectively. The system uses the Visual Studio C+ +6.0 programming language and MS SQL Server 2005 database technology to realize the communication between the COM port and the RFID reader, RFID card configurator and ID card readers through the WINDOWS API and CSerialPort class library. By matching the data record in RFID readers and in RFID card configurator module, the personnel location can be obtained in real time to realize the personnel orientation and management. The practical application shows that this system can finish acquiring and updating the data fast and stably, and effectively solve the orientation problem of the persons far from scenic spots.
