Based On Gprs Embedded Internet

With high rapid developments of Internet network, Internet has made a great affects on the developments of modern society. The embedded internet technology enables electronic instruments to access Internet which makes remote detection, remote control and remote maintenance easy. The application of embedded internet technology must have great future in fields of industrial control and information electronic equipments, etc.General Packet Radio Service (GPRS) is the new bear service which is developed from GSM network. GPRS networks provide packet-switched services based on internet protocol (IP),which make End-user can access the external packet data network--Internet. The data communication based on GPRS has so many features such as "online forever", fast data transmitting and the bill is cheap.The embedded system which has been completed used the CPU based on the ARM core, and use MC35 as communication module. The software has been developed under the embedded operation system: μC/OS-II. Using GPRS network, the equipment has realized the embedded internet technology.In conclusion, the main works of this paper are described as following:1,Finished the embedded development hardware platform design which is based on ARM7TDMI core;2,Accomplished to port μC/OS-II to the platform;3,Implement UDP/IP/PPP/ICMP protocols on the embedded system, and the system can detect online or not and redial to access internet again by itself.The result of experiment shows that the equipment has the characteristics of steadiness, reliability, and fast data transmitting and cheap. It fulfilled the scheduled remands.
