摘要
随着信息技术的发展,智能化的考勤系统已经成为现代化企业架构的必备设施.设计了一种基于MSP430单片机和TRF7960射频芯片的读卡器,实现了对支持ISO14443A协议无源电子标签的查询和防碰撞算法,读卡距离约8cm,最多允许2张卡片同时读卡.读卡器具有性能稳定、功耗低等特点,结合服务器端系统中间件和Web应用软件的开发,实现了一套考勤系统的完整解决方案.
With the developing of information technology, smart attendance system has been an essential facility for modem enterprise. In this paper, a low-power RFID system based on MSP430 and TRF7960 is designed. The reader can inquire passive tags which support ISO14443A protocol and has been planted with anti-collision algorithm. It has a read range of 8cm and can read 2 tags at the same time. Experimental results verify that the RFID reader is stable and reliable. Combined with the development of middle-ware and Web service application at the server, a complete solution of attendance system is achieved.
