摘要
地铁列车司机显示单元(DDU:Dirver Display Unit)作为列车网络的重要部分,是完成人机对话和系统信息显示的重要系统。为驾驶员的操作及地铁车辆安全运行提供信息保证。本设计选择X86架构计算机作为DDU单元的硬件平台,嵌入Linux操作系统,构建了基于CANopen通信协议的地铁列车司机显示单元。本文详细介绍了DDU的系统原理和软件架构设计。
The Driver Display Unit（DDU） was as an important part of the train network to implement the human-machine interface and information display.The DDU provided the information for the operation of driver to assure the safety of the subway train.This paper chose the X86-CPU base hardware as the hardware platform of DDU and Embedded Linux Operation System to build the DDU based on CANopen protocol,introduced the system principle and the software architecture design of DDU in detail.
