| The appearance of Networked Tele-control System materialized the cross of two subjects between automatic control technology and computer network technology. Network technology has had extensive application in many fields of the society. The application of network technology in the control field was essentially the mapping from computer network technology to automatic control technology, which resulted in the naissance of a researching field, that's the researching of Networked Tele-control System.The two control modes of Networked Tele-control System were introduced, i.e. remote monitoring and networked closed-loop control. In order to analyze and simulate the two control modes respectively, and to analyze the impact of time-delay to networked closed-loop control, the simulation software of Networked Tele-control System was designed and realized. A simulation platform based on real network was built for the researching of theory. The simulation software was based on Client/Server model, which was divided into two parts in logic, Client terminal and Server terminal. Through experiment, the validity of the simulation platform was proved and the result of simulation was analyzed. |
