Methods of and Real- Time Analysis on Network Control System and its Application

This paper describes in detail on distributed control computer system, analyzes its structure, features and time-limit requirements and presents that the real-time transmission and reliability is the key to realize time restriction. Meanwhile it also studies and analyzes the basic realization technique on communication LAN of spot bus, industrial Ethernet and real-time network as well as its limitation; then draws the conclusion on this basis that it's necessary to use 1553B bus, Ethernet and SBS real-time network techniques to conduct the design on avionic simulator.
