Abstract: The normal operation of modern trains is inseparable from the cooperation of mechanical and electronic systems,especially the train control and management system(TCMS) plays a key role in it.TCMS-related applications and services run on the train communication network(TCN),which is wired and often redundant,resulting in a large number of wired links interconnection,making network deployment and maintenance difficulties,and poor flexibility.This paper proposes a Wi-Fi 6-based train wireless communication networking scheme,which applies Wi-Fi 6 technology to the vehicle-level ECN network.The work includes the design of network architecture,the selection of communication data and the experimental verification in simulation environment.Experimental results show that the proposed Wi-Fi 6-based train communication QoS in terms of delay,jitter and packet loss rate meets the IEC 61375-3-4 standard,and have advantages over long term evolution(LTE).
