| With the development of the high-speed and automation of the new generation train, TCN (Train Communication Network) is the key technology in the control system of high-speed electrical train. This standard integrates the train control, failure monitor and process of passenger service information. Therefore, there is no doubt that the research and the application of the devices conforming to the international standard of TCN will have very promising future.This thesis analyses the Train Communication Network, especially the MVB (Multi-function Vehicle Bus), and then proposes the design of the MVB master card and gives the implementation of the hardware and software.Firstly, this thesis introduces the development state of the TCN and MVB, and analyses the development of embedded system and EDA(Electronic Design Automation). Secondly, through the analysis of the software and hardware platform, this thesis gives the design and implementation of the master card based on Nucleus Plus embedded real time operation system, ARM processor AT91R40008 and Xilinx's Spartan-II series FPGA(Field Programmable Gate Array) XC2S200. The master card makes a good use of the advantage of the high-performance, low-power and low-cost of ARM microprocessor and the high-density, low-cost of FPGA. The master card is designed with PC 104 bus interface and excellent processing power and conforming to the TCN standard. Finally, the thesis gives the result of the transfer of process data and the expectation of the development. |
