摘要： 现代列车的正常运行离不开机械和电子系统的相互配合,特别是列车控制和管理系统(TCMS)在其中发挥着关键作用。与TCMS相关的应用程序和服务运行在列车通信网络(TCN)上,该网络是有线的且通常是冗余线路,这就会造成大量的有线链路互联,导致网络部署和维护困难且灵活性差。提出了基于Wi-Fi 6的列车无线通信组网方案,该方案将Wi-Fi 6技术应用于车辆级的ECN网络中,所做的工作包括对网络架构的设计、通信数据的选择和仿真环境下的实验验证。实验结果表明,所提出的基于Wi-Fi 6的列车通信服务质量中时延、抖动和丢包率满足IEC 61375-3-4标准,相对于长期演进技术(LET)也占据了优势。
