摘要
研究了高速动车组列车网络控制系统的过程数据调度及事件仲裁算法。针对高速动车组网络控制系统的特点,提出了列车网络控制系统主节点和从节点的实现算法,并利用OPNET仿真软件建立了列车网络控制系统的模型。在不同的仿真场景下运行仿真模型,通过对仿真和理论计算得到了列车通信网络协议的数据通量和端对端延时特点。针对消息数据的事件仲裁机制,通过仿真得出了不同条件下的碰撞特性。仿真结果表明了所提出方案的有效性,为实际高速动车组网络控制系统的设计和调试提供了依据。
The process data scheduling and events arbitration algorithm of high-speed electric multiple unit(EMU) networked control system(NCS) were researched.The train NCS master and slave node algorithm was proposed and its simulation model was established for its characteristics based on OPNET software.The data throughput and end-to-end delay characteristics were achieved under different simulation scenarios by simulation and theoretical calculation.Under different conditions,the message data collision characteristic for event arbitration mechanism was obtained.Simulation results show the effectiveness of the proposed scheme and this novel method offers a basis for the actual high-speed EMU NCS design and commissioning.
