Research On Development Technology Of Remote Monitor And Control System Based On Web

With the development of network and Web technology at full speed, great changes have been taking place in conventional monitoring and control Model. On the Internet/Intranet, the application of Web to remote monitor in industrial enviroment is the developing direction of monitoring and control system.The hierarchical model of network remote monitoring and control system is studied and the architecture of remote monitor system based on Web is proposed in the thesis.In terms of monitor system integration, the thesis has discussed various kinds of technology involved in remote monitor system based on Web, including the technologies of development of Web application and accessing database and communication in network enviroment; and provides various Web-based remote monitor projects with different data communication technology. According to the real-time requirment of Web-based remote monitor system, the thesis also analyses in detail the publishing of real-time data in Web usinging ActiveX and Java Applet; and adopting technology of Socket communication, puts forward the software design for Web-based remote monitor system and questions needing paying attention to in the design.According to the design project of Web-based remote monitor system, a remote monitoring experiment is designed in the thesis in basis of laboratory apparatus of coupled-tanks based on PLC,and the function of every part of the system and implementation method is explained. In the end, operating the a remote monitoring experiment system shows the feasibility of implementing the remote monitor system based on Web.
