【摘要】 随着列车高速化、自动化的发展,集列车控制、故障诊断以及旅客服务信息处理于一体的列车通信网络(TCN-Train Communication Network)技术已经成为高速电力列车上控制系统的关键技术。符合国际标准的列车通信网络设备的开发与应用有着极其广阔的前景。本课题在分析列车通信网络特别是多功能车厢总线(MVB -Multifunction Vehicle Bus)的前提下,提出了基于FPGA的MVB通信控制器的设计方法,并给出了硬件和软件的具体实现。本文在第一章中根据国内外列车通信网技术的对比,引出本文要解决的问题。随后在第二章和第三章针对研究对象TCN及MVB的通信机制进行了深入研究,为MVBC的设计实现做了铺垫。第四章和第五章针对MVBC的总体及内部各个模块进行设计,实现各个模块的功能,使之符合MVB通信标准。第六章对MVBC的各个模块进行FPGA验证。第七章对全文进行总结和展望。MVBC设计采用自上而下的EDA设计方法和功能相关的模块分组验证方法,电路设计采用Verilog代码描述,仿真工具采用ModelSim,综合与FPGA验证采用Altera的集成开发环境Quartus。目前各个模块的代码设计已完毕,并通过了软件仿真,正在进行FPGA板级验证工作。列车车辆的现代化的发展趋势与可靠性、安全性、通讯实时性的要求使MVB有着广泛的应用前景。本设计在该领域上填补了国内的空白,为我国实现TCN的自主开发形成了一个突破口,同时自身也具有巨大的市场价值和技术价值。更多还原

【Abstract】 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 (Muftifunction Vehicle Bus), and then proposes the design of the MVB controller and gives the implementation of the hardware and software.Based on the comparison of domestic and international train communication network technology, the paper leads to the problem that to be solved. Then in chapter II and III conducted in-depth study of the communication mechanism. Chapter IV and V make a overall desian of MVBC; and also the internal modules of MVBC. Chapter VI is the verification of various modules of FPGA for MVBC. Chapter VII is the sum up of the paper.This design adopts Top-down EDA design flow. The simulation tool is ModelSim, the synthesis tool and programming tool is the Quartus. Now, coding design and simulation have passed through, the FPGA system test of board level is on the way. MVB has the foreground of wide application by the trend of modern development of train and vehicle and the requirement of reliability, safety,time-critical. This design supplies a gap in the domain of TCN in our country, acts a gate for the realization of independent developing TCN, and has great market value and technology value by itself..更多还原
