Design And Implementation Of Embedded Web Server Based On WinCE

The research of EWS (Embedded Web Server) technology is a hot topic in embedded system. With the rapid development of embedded system and Internet technology, EWS based on ARM SOC processor, WinCE software platform and ActiveX technology can not only implement complex interactive page but also effectively cut down the load of embedded system, which can effectively implement Lean-Server. It has gradually become one of study hot and has broad application prospect and research value.This paper mainly studies EWS and its design and implementation based on Windows CE OS. Firstly the basic theory of Embedded Web Server is analyzed. Then the design principals of two kinds of application including Fat-Server and Lean-Server of EWS are compared. On the basis of presenting the design solution of EWS based on Windows CE OS, this thesis carefully does research on developing process and method of bootloader, OAL (OEM Adaptation Layer) and device drivers, emphasizing on analysis of the realization and transplant of serial and NAND Flash drivers, detailed design solution is provided as well. Finally the design methods of application layer in Server and ActiveX control design step in Client are mainly discussed, and a Lean-Server based on Windows CE OS with good HMI (human Machine interface) is designed. This server has the advantage of simple structure, easy operation and can implement complicated applications, which offers significance for its wide adoption in the future to some extent.
