摘要
城市轨道交通车辆通常在司机室配置车载信号屏、HMI和CCTV屏,并分别接入列车网络,根据列车通信网络常规设计,在MVB通信中每个源端口同一时刻只能对应一个设备。宁波地铁4号线采用多屏融合技术,多个设备配置了同一个源端口,不同的端口配置通过应用程序调用。针对宁波轨道交通4号线自正式开通以来所发生的网络干扰故障,从原理到数据进行分析,并结合硬件设计提出针对性整改措施,确保电客车正线运行安全性和可靠性。
Urban rail transit vehicles are usually equipped with onboard signal screens,HMI,and CCTV screens in the driver's cab,which are respectively connected to the train network.According to the conventional design of train communication networks,each source port can only correspond to one device at a time in MVB communication.The Ningbo Metro Line 4 adopts multi-screen fusion technology,where multiple devices are configured with the same source port,and different port configurations are called through application programs.In response to the network interference faults in the Ningbo Metro Line 4 since its official opening,we proposed the targeted rectification measures on the basis of principles,data analysis,and hardware design to ensure the safety and reliability of electric passenger cars operation on the main line.
