融合GPRS与嵌入式以太网技术的指纹考勤系统设计

摘要

In this paper, by integrating the techniques of GPRS, embedded Ethernet, flash memory and intelligent power management, we designed a fingerprint Time and Attendance System, which is based on embedded Ethernet module integrated microcontroller MCF52223 (produced by Freescale Corporation) and GTM900-B of HuaWei Company. This design has some excellent advantages, such as optional communication mode, offline attendance checking supported and intelligent power management, can meet the needs of diverse attendance management. As the fingerprint is unique and can not be replicated, it eliminates the problem of surrogated attendance checking in IC attendance system. This research can be the reference to similar applications.%结合GPRS、嵌入式以太网、Flash存储、智能电源管理等技术,并以Freescale公司集成嵌入式以太网模块的MCF52233微控制器和华为GTM900-B为基础,设计了融合GPRS与嵌入式以太网技术的指纹考勤系统.该设计具有通信方式可选、支持脱机考勤、智能电源管理等特点,满足了考勤管理的多样性需求.同时由于指纹的唯一性和不可复制性,杜绝了IC考勤中的替考问题,可为同类应用借鉴.
