An Architecture for Embedded Web Server Based on OPC
On the basis of research on Embedded system and Web technology,this paper applies OPC (OLE for Process Control) to Embedded Multiprocessor DCS (Distributed Control System) and designs a new EWS (Embedded Web Server), in which a layer of OPC XML-DA (Data Access) is added between Web client and inter-server. Then real-time and security of the architecture are analyzed. This EWS applies such technologies as OPC, Java and XML and links to Internet through TCP/IP. Therefore, accesses to all kinds of Embedded devices and data share in the heterogeneous Internet/Intranet environment are implemented. The experiments and application have demonstrated that the architecture has good performance and is feasible for real-time operation in DCS.
