| Embedded technology is a new pet of the information technical development, and more and more embedded products require having the ability to the access networks. TCP/IP is a essential communication protocol in internet communication at present. Studying TCP/IP technology based on embedded system will undoubtedly have important value to the development of the embedded information products. This paper firstly introduces basic conception, system making up, application and future development trend of the embedded system, further discusses a new method of interconnecting the embedded equipment and Internet ——realizes embedded system access network through simplifying the communication agreement, and emphatically describes the transplantation of the embedded real-time operating system μC/OS-II based on ARM microprocessor, which is regarded as a system platform, and realizes a set of intact embedded TCP/IP protocol stack based on it, finally apply this protocol stack to check meter wirelessly in the power system and the application in industry's Ethernet.
