Research And Soft Realization Of Remote Monitoring And Controlling System Based On B/S Mode

With the development of the network technical, Internet technique has already penetrated to each field of the daily life and the industry production .It made the real-time remote monitoring and control of the running of equipment possible. Through the remote monitoring and control technique, the technical operator needn't to attend personally or to be in bad environment. Remote monitoring and controlling system is a combination of network technology, computer technology and control technology. It provides an effective monitoring method for monitoring in intranet and across areas by utilizing available basic devices for LAN and WAN adequately. Considering the requirement of management and market's application, thesis present the research and soft realization of remote monitoring and controlling system based on B/S by introducing the B/S for control system.At first, the research significance and present situation of remote monitoring and controlling system based on B/S mode are introduced in this thesis. The network architecture model, application and exploiting environment, functional constructions of server and browser and software design techniques based on B/S are also proposed and discussed.After analyzing the major techniques generally used in remote monitoring and controlling system based on B/S mode, a typical B/S mode of remote monitoring and controlling system is built up in this thesis, water supply remote supervising system. And the function, structures are discussed;every modules of the software, data storage, data inquiring, maintenance of database are analyzed in details. Then the developing platform and developing tools are introduced.On the other hand, because of the character of remote monitoring and controlling system based on B/S mode, real-time character and network security are of great importance, the fundamental definition of real-time performance and the corresponding measure are expounded. Then the basic security techniques for network communication are presented, and some steps are brought forward for the whole remote monitoring and controlling system. At the end some safetyrealizing ways of water supply remote monitoring and controlling system are discussed briefly.At last, some real-time remote monitoring and control technology is prospected.
