Study On Remote Monitoring And Control System Based On The Internet

With the development of science and technique, the importance of monitoring and control technology has being understood and recognized gradually overall the world industrial and agricultural fields. The combination of monitoring technology, computer technology and communication make Internet spreader and developed rapidly in the field of measurement and control system. In the situation of equipments distributed widely and data acquisition difficult the remote monitoring and control technology is needed to monitor and control the operating state of equipment in time. The paper introduce clients monitor and control the remote measurement system through Internet.The C/S (Client/Sever) technology that has the advantage of easy and effective has being the most widespread information exchange platform of Internet. The paper study real-time remote monitoring and control technology and design a real-time monitoring and control system based on C/S model. The system both use development platform of LabWindows/CVI and make full use of Internet communication, data acquisition, and object oriented programming technology to perform system management, user management, equipment monitoring, data display and alarm function. There have many advantages in this system such as taking full advantage of network resource and higher quality network communication. The system operation interface is simple, standard and vivid. User can run the system conveniently. The special software can deal with much of tedious work so the user can ignore the source of the data and how to put them together into an orderly, functional, structured whole.Because of the difference of the Internet network and the control network in characteristics, how to realize the integration of information and how to analyzed them are the key question in this paper. This paper introduces TCP/IP, DataSocket and dynamic data exchange technology. This paper studies the real-time character of the remote monitoring and control system, and puts forward some measurement methods depending on experimentation. The paper introduces the basic network safety and presents some methods to make Internet communication safer in three layers C/S model. This paper also introduces anti-jamming measurements of software and hardware. At last, the paper proves the system dependable through a sample.
