MVB1类设备控制器的软件设计 MVB1 kind of equipment controller software design 学 院：电气工程学院 专 业 班 级：电气工程及其自动化0806班 学 号：080301192 学 生 姓 名：李云龙 指 导 教 师：林莘 （教授） 2012年06月 MVBI类设备控制器的软件设计 摘要 列车通讯网络广泛应用于高速列车，列车高速化发展成为必然的趋势，这就对其发展有了更高的要求。MVB控制器用于实现车辆内设备与MVB之间的通信，在列车通信网中起着举足轻重的作用，但是目前该项技术被国外的几个公司如Bombardier，Siemens等垄断，致使在国内购买昂贵。所以，研制MVB控制器，开发具有自主知识产权，对我国列车通信网络的建设有重要意义。 正是由于这些原因，本文对MVB技术进行了研究，提出了采用FPGA代替MVB控制器专用芯片的解决方法。该设计采用典型的自顶而下的模块设计方法，根据MVB1类设备控制器要实现的功能，本设计主要研究发送模块，并对发送模块中各个单元进行逐一设计。在Altera公司的集成开发环境Quartus II软件上用VHDL硬件描述语言进行程序编译、仿真与综合。 采用FPGA代替MVB1类设备控制器对打断国外在该核心技术上的垄断，推动我国列车通信网络技术发展，以及研发出具有自主知识产权的MVB产品具有非常重要的意义。 关键词：列车通信网：多功能车辆总线：MVB1类设备控制器：FPGA MVB1 kind of equipment controller software design Abstract Train communication network are widely used in high speed trains, and train high development is an inevitable trend, it is its development had the higher request. MVB controller used to implement the vehicles equipment and the communication between the MVB, train communication network in plays an important role, but now the technology was foreign several companies such as Bombardier, Siemens monopoly, which buy expensive in China. So, the development MVB controller, development with independent intellectual property rights, to our country of train communication network construction to have the important meaning. For these reasons, this paper MVB technology, proposes an MVB controller based on FPGA instead of the special chip solutions. This design USES the typical from top to bottom module design method, according to MVB1 kind of equipment to realize the function of the controller, the design research send module, and to send in the module design one each unit. Altera company in the integrated development environment Quartus II software with VHDL hardware description language on the program compiled, simulation and comprehensive. Instead of MVB1 kind of equipment based on FPGA to interrupt controller in the core technology abroad monopoly on, promo
