摘要
随着轨道交通技术飞速发展,列车控制系统逐步从传统的多功能车辆总线网络向以太网过渡,与此同时,列车智能运维网络与车辆乘客信息系统网络也被广泛应用。在此背景下,将轨道交通列车中大量的以太网网络融合,并共用管理设备,可有效降低运营企业运维工作量和系统故障率,因而轨道交通多网融合方案在建设项目中备受青睐。鉴于此,文章深入研究轨道交通列车网络拓扑结构,详细阐述其演进过程与现状,针对性地提出2种创新型网络融合方案并开展多维度对比分析,旨在为车辆设计人员在设计阶段提供科学、详实的参考依据,推动轨道交通列车网络技术的发展与应用。
With the rapid development of rail transit technology,the train control system gradually transitions from the traditional multifunctional vehicle bus network to Ethernet,and at the same time,the train intelligent operation and maintenance network and vehicle passenger information system network are also widely deployed.In this context,the interworking of a large number of Ethernet networks in rail transit trains and the sharing of management equipment could not only effectively reduce the operation and maintenance workload of the operating enterprises,but also the failure rate of the system,and thus the multi-network interworking scheme for rail transit is strongly preferred in the construction project.In view of this,this article conducts an in-depth study of the structure of rail transit train network topology,details its evolution and status quo,and proposes two innovative network interworking schemes and carries out multi-dimensional comparative analysis,with the aim to provide vehicle designers in the design stage with a scientific and detailed reference basis,and to promote the development and application of rail transit train network technology.
