智能GPRS传输终端嵌入式系统构建

Embedded System Construction for Intelligent Terminal of GPRS Transmission

目的:在ARM9硬件平台上构建一个嵌入式Linux系统,使其符合GPRS传输终端的智能化要求,为移动医疗研究提供支持。方法:在EL-ARM-830实验教学系统上移植嵌入式Linux系统,构建添加QT的图形界面支持的文件系统,再为GPRS应用添加必要的设备驱动、拨号脚本、配置文件等。结果:在目标板上运行测试构建好的系统,测试结果表明,移植后的Linux运行稳定,网络连接无误,能达到GPRS传输终端的智能化需求。结论:此方案可直接应用于S3C2410平台的嵌入式Linux系统环境构建,应用于智能终端设计中可加快后续研发的进度,为移动医疗智能终端的实现奠定了基础。

Objective To construct an embedded Linux system based on an ARM9 hardware platform to give a support for mobile telemedicine research according to requirements of intelligent terminal for GPRS transmission.Methods The terminal was transplanted with the embedded Linux operating system,and established file system with a graphical interface based on QT combining with applications support for GPRS such as necessary device drivers,dial-up scripts and configuration files.All work played on EL-ARM-830 experiment teaching system platform of Jing Yi Da Sheng Technology Company in Beijing.Results Test results showed that embedded Linux system ran stably and network linked successfully,which achieved the demands of intelligent GPRS transmission terminal more.Conclusion This scheme can be directly applied on embedded S3C2410 platform to build Linux system environment,also accelerate the follow-up RD progress of design of intelligent terminal surely and make a solid foundation for the realization of mobile telemedicine＇s intelligent terminal.
