| 摘 要： | 为满足高速磁浮列车车载诊断系统通信平台的要求,提出了一种基于RTLinux(real-time linux)的通信平台设计方案.该方案包括基于RTLinux通信平台的结构设计、实时和非实时处理模块的设计与实现.通过讨论CPCI-CAN(compact peripheral component interconnect-control area network)卡在RTLinux下驱动程序的开发过程,给出了驱动程序的具体实现.最后,借助调度时间模型和传送延时模型,分析了该车载诊断系统通信平台的实时性.实时仿真结果表明:基于RTLinux的通信平台中,所有节点完成网络更新的时间平均为290 ms,满足高速磁浮列车通信平台响应时间小于500 ms的要求.

| Abstract: | For the demand of an on-board communication platform for high-speed maglev trains,a plan based on RTLinux(real-time linux) was proposed,including the architecture design of the communication platform based on RTLinux,the designs and realizations of real-time and non-real-time processing modules.The driver program of RTLinux for CPCI-CAN(compact peripheral component interconnect-control area network) board was given and realized through the discussion of program development.In addition,the real-time performa... |
