Research And Design On The Medium Distribution Arithmetic Of MVB In Train Communication Network

With the development of the science and technology, the railway interests need a new improving. The next generation of challenge is the vehicle automatism joining technology with data bus. It requires the worldwide standard of the communication between vehicles.IEC-61375 is an IEC standard for Train Communication Network. TCN is divided into train level communication network -- WTB which is used for connecting each dynamically organized vehicle and vehicle level communication network -- MVB which is used for connecting fix devices in vehicle. This subject is on the basis of studying network structure of train communication network, have designed and realized the embedded platform of TCN gateway equipment that accord with the international standard IEC 61375.The MVB is the standard of realizing the data communication in the vehicle. It detailed defines the processing of the data transmission on the bus. It's the most important chain in the TCN. Due to this, the paper sets the keystone on the research of the algorithmic and the realization of the program. The paper has depicted and compared two sets of projects, and particularly discussed recommend precept's excellence, At last, it gives the conclusions and the improving suggests for the more research and upswing.
