Abstract


With the continuous progress of human society , information technology , network technology has become the development trend of the industry inevitable . One of the giants as traffic , the railway industry need for such a communication platform for rolling stock between internal and train vehicles , as well as between the train and the ground control system for the control of information , diagnosis and passenger information services , in order to achieve its information and networking . In 1999 , the International Union of Railways and the International Electrotechnical Commission jointly formulated Train Communication Network (TCN, Train Communication Network) network communication standard IEC 61375-1 , common international standard as TCN network . Developed TCN standard network equipment , the construction of the national railway information necessary requirements . In this thesis, the TCN gateway device development background, study the MVB module FPGA implementation . Thesis from MVB agreement TCN network protocol level functional point of analysis of the MVB network communication principles and communication conventions , combined the TCN gateway project MVB module functional requirements , top- down design methodology proposed MVB module implementation of the overall program , and gives a frame transceiver , RAM storage unit, a link control unit , the module specific design method . In the same time, the paper elaborated packet timing , bus arbitration , the transfer of sovereignty , the key technologies involved in the hot backup MVB module design , including the transfer of sovereignty and hot backup MVB module design new attempt . After the simulation of the system , the design of better MVB module polling TCN gateway , message communication , hot backup and other basic functions . The research papers from the theoretical agreement to the concrete realization of the program as well as the analysis of the key technologies to provide a more comprehensive technical support , for the TCN network MVB equipment to achieve their own strength , contribution to the development of information technology in China 's railway industry .
