The Design, Research And Realization Of Real-time Communication Protocol In Control Networks

With the rising of the basic position of enterprise informationalization in the national economy and social information , and the deep research on Real-Time System, Real-Time System has been applied in more and more fields. Adopting Real-Time System in the communication of control networks will change the work mode of original control networks, and present a new work mode ?Real-Time Scheduler.The first chapter of this paper gives a brief introduction to the development of communication protocol in control networks. The second chapter discusses some protocols that are currently used. The third chapter introduces some concepts of Real-Time System and the differences between Real-Time System and Real-Time operating system. The forth chapter analyses some designing methods of the Real-Time System in detail.In the last part of the paper, a design example about the Real-Time communication protocol is given according to the author's own experience.
