摘要
文中所实现的嵌入式Internet技术是利用了GPRS网络将设备以无线方式接入Internet的技术。监控系统采用了基于ARM核的Samsung微处理器作CPU,GPRS通讯模块采用技术先进、功能完备的H7118C型GPRS DTU,软件功能在嵌入式实时操作系统μC/OS-II下编程实现,选择UDP协议进行通信,采用动态域名解析技术解决了动态IP的问题,并建立了功能完善的监控中心。系统采用模块化设计,便于以后的升级和扩展。研究结果表明:该设备具有稳定可靠,实时性强,传输速度快,运营费用低等特点。
The embedded system in this paper is a technique which implements access to the Internet by GPRS. The monitor system adopts ARMcore based Samsung as CPU and GPRS communication module adopts H7118 with advanced technology and complete function. The software function is realized by realtime embedded operation system μC/OS-II. The UDP protocol is chosen for communication, the dynamical resolution technology of domain name solves the dynamical IP problem, and the monitoring center with perfect function is established. The system adopts modular design and is easy for future promotion and expansion. The simulation results indicate that the equipment is reliable in performance, robust in real time, fast in transmission, and cheap in operation, thus has achieved the scheduled demands.
