Research And Application Of Web-based Remote Real-time Monitoring And Control System

With the development of network technology, remote monitoring and control technology combines with network closely. The hierarchical model of network remote monitoring and control system is studied. Infranet technology and the integration of the Infranet and Internet/Intranet are analyzed and studied in detail. A Web-based remote monitoring project is proposed according to the comparison of different software modes.In order to realize dynamic data exchange and real-time communication, some methods to improve real-time capability of Web-based remote monitoring and control system are analyzed and studied in this thesis. Java Applet technology, Socket network communication technology and OPC technology are discussed in detail.The Web-based real-time remote monitoring and control technology is applied to the hydro power remote monitoring and control system in order to realize the automation reconstruction of hydro power, and the structure of hardware and software is described in detail. In this scheme, Ethernet is applied to infranet , and OPC technology is used to data acquisition from local control unit. Socket communication and Java Applet technology are used to realize real-time data exchange.According to the design project of hydro power remote monitoring and control system, a remote monitoring experiment system is designed in this thesis. The communication scheme, the function and realization of experiment server are introduced in detail. In the end, remote monitoring experiment system of solid warehouse is realized which displays the feasibility of the scheme.
