The Research And Implementation Of Web Based Digital Supervising System

With the advances of technologies of network and WWW, real-time supervising systems are also beginning to have distributed and thin clients with the help of Web technologies. Web based remote real-time supervising technologies have emerged as hot researches.To meet the need of constructing a real power supervising system (YSS), some technologies of Web based digital supervising network are studied in this thesis deeply, completely, and in detail, and based on these studies, a dynamic real-time data publication model using SVG+XMLHTTP+Javascript is presented, and is also applied successfully in developing the Web based supervising functions of YSS system.. Topics of how to design the system's architecture using Web Service and CORBA to improve its scalability and ability of integrating with other information systems are also discussed in the thesis. Moreover object models of various elements of GUI including polyline, virtual ampere meter, button, etc., supporting SVG for digital supervising are studied and presented, they are useful to other similar research project.
