摘　　要：在有线网络车车通信方式下,列车之间因频繁联挂和解编,容易造成连接器磨损,从而导致通信不稳定甚至中断。文章针对地铁应用场景,以无线连接代替有线连接,设计了基于V2X的无线车车通信系统,可以实现列车间的快速联挂,减少操作难度与时间,降低了通信故障。为提升可靠性,文章设计了双设备双链路冗余方案,并研制了无线通信网关。在室内、户外和实际线路等场景下进行了实测验证,结果表明,该系统支持隧道内通信,通信距离大于500m、时延小于100ms、收包率大于99.5%,可满足地铁车车通信的需求。In wired network vehicle-to-vehicle communication systems,frequent coupling and decoupling between trains can easily lead to connector wear,resulting in unstable communication or even interruptions.This paper proposes a wireless vehicle-to-vehicle communication system based on V2X as an alternative to wired connections,focusing on metro application scenarios.This design enables rapid coupling between trains,lowers operational difficulty and time consumption,and reduces communication failures.To enhance reliability,a dual-device dual-link redundancy configuration was devised,along with a wireless communication gateway.The proposed system was verified through actual measurements in various scenarios,including indoor,outdoor,and real track environments.Results demonstrated the system's capacity to support communication in tunnels,achieving communication distances exceeding 500 meters,latencies of less than 100 ms,and packet reception rates above 99.5%,thereby meeting the vehicle-to-vehicle communication requirements for metro transportation.
