中文摘要：
研究基于多功能车辆总线（MVB）的机车逻辑控制单元,分析了目前国内外多功能车辆总线的发展状况及自主研制MVB总线控制器及MVB网络接口卡对于我国轨道交通的现实意义,介绍了基于MVB总线的机车逻辑控制单元的系统结构,重点研究了MVB网络接口单元的构造及功能;以自主开发的MVB总线控制器为核心,设计研制了一种MVB总线的网络接口卡,为设备与MVB总线提供通信手段,利用TMS320LF2407实现数据的处理及设备与MVB总线的通讯控制;实验证明,该方案完全可行。
英文摘要：
The locomotive logic control unit based on multifunction vehicle bus is studied, besides this, the components and their functions of the LCU are described, the system structure of the locomotive logic control unit based on the MVB is also recommended. Taking MVB controller developed by ourselves as the core, the network interface card of MVB has been designed. Data process and communication control between device and MVB bus are accomplished by DSP , at last, the software realization of this system is presented. The scheme is feasible by experiment.
