摘要

针对目前铁路上的MVB 接口单元几乎只能应用于MVB-cPCI 或MVB-PC/104 两种通信方式的局限性，提出了一种新的通信方案，即通过ARM芯片检测总线连入状况，自动引导对FPGA 配置不同的程序，以实现在同一个MVB接口单元上完成MVB与其他系统总线（如MVB-USB、MVBEthernet 总线等）互连通信的功能。所设计的MVB 接口单元能实现MVB 与其他系统总线互相传输数据，能增强MVB 与外界信息交换的能力，克服车载设备间、车载设备与非车载设备间的兼容性低的缺点。该研究不仅从理论上阐述了基于FPGA 的多种系统总线互连的接口设计，还实现了样板设计，并进行了互连通信测试。试验结果表明，这种研究不仅能实现多总线互连通信，还可应用开发高访问速率的TCN5 类设备。

Abstract

For the limitation of MVB cards in railway only adapting in MVB-cPCI or MVB-PC/104 bus, a new communication method was given, by detecting buses connecting status with ARM microprocessor, automatically loading different procedures upon FPGA, to realize the interconnection of MVB communicate with other system buses (such as MVB-USB, MVB-Ethernet bus, etc.) by the universal MVB interface unit. With the designed universal MVB interface, application range of MVB cards extended, and compatibility of on-board devices was enhanced. Interface design of multiple system buses connection based on FPGA was expounded theoretically, and the prototype was realized and tested, which showed that this study could be used to develop the high-rate-communication devices of TCN5.
