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 Internet technology that this text realizes is a technology that makes use of GPRS network to connect the apparatus to the Internet wirelessly. Monitoring system uses a Samsung ARM microprocessor-based microprocessor CPU, GPRS communication module using advanced technology, fully functional H7118C GPRS DTU, the software features in the embedded real-time operating system μC / OS-II programming, select the UDP protocol To communicate, the use of dynamic domain name resolution technology to solve the problem of dynamic IP, and established a fully functional monitoring center. System uses a modular design, easy to upgrade and expand later. The results show that the device is stable and reliable, real-time, transmission speed, low operating costs and so on.
