基于无线网络的非接触式IC卡考勤系统的设计

Design of the attendance check system based on non-contact IC's card reader and wireless network

采用射频识别技术及无线网络通信技术,设计一种由主控机PC、无线射频模块和读卡器模块3个主要部分组成的考勤系统。详细介绍了系统硬件结构设计原理及实现方法,给出了考勤系统软件设计思想及主要程序流程图。实际调试表明:该系统能够实现对考勤现场数据的实时录入、多点采集和无线传输等功能,且具有数据传输有效距离远、移动性强、安装简单和扩展性好等优点,具有一定的推广价值。

The attendance check system is accomplished by three parts,consisting of host control module,RF module and non-contact reader IC＇s card reader module.It uses the radio-frequency technique and the wireless network technique.The hardware design and software flow process diagram of the attendance check system are introduced in this paper.Many functions including of real-time logging data,multiplex data acquisition and wireless transmission are realized.There are many good features in the system,such as far operating range,convenience mobility,adjustment,strong augmentability and so on,so it will be used extensively in the future.
