The Design of Rail MVB Communication Network
Abstract: With the rapid development of distributed field bus technology, computer technology and train local area network technology, many countries in the world have successfully developed the train communication network , which has its own characteristics. MVB communication network has high reliability, real-time, high security, etc., while in line with the development requirements of TCN, which makes MVB becoming the next generation of vehicle communications bus standard. This paper describes the major domestic and international train communication network technology features, analyzes the content and meaning of the status quo and MVB communication network of research. By introducing structural principle of MVB communication network, the network communication process and network topologies, specifically addressed the aspects of the content interface device type MVB communication networks, media distribution and network sovereignty transfer. On this basis, the use of MATLAB and Simulink software toolkit to train communication network simulation design, based on the results of the simulation analyzes the factors that affect the transmission of data and network transmission delay, and network performance were analyzed and discussed.
