摘　　要：随着我国城市轨道交通的发展,列车智能化水平不断提升,车辆接入TCMS(列车网络控制系统)的设备不断增多,传输数据急剧增加,列车通信网络需要具备大吞吐量以及灵活组网的能力,MVB(多功能车辆总线)架构网络因其传输速率低等局限性,已无法满足多系统控制融合、多资源信息共享的智慧列车通信网络综合承载的需求。对比分析了以太网网络与MVB网络的特性,介绍了基于交换式以太网列车综合承载网络的车辆级通信方案和列车级通信方案的特点。基于交换式以太网的综合承载列车通信网络具有高带宽、高速率、高安全性、高稳定性、高兼容性、高灵活性及低成本等显著优势。With the development of urban rail transit in China,the level of train intelligence has been continuously improve,the equipment number for vehicle access to TCMS(train network control system)is increasing,and the transmission data has increased dramatically.The train communication network requires large throughput and flexible networking capacity,but limited by low transmission rate,the MVB(multi-functional vehicle bus)architecture network can’t meet the requirements of comprehensive bearing of intelligent train communication network that multi-system control integration and multi-resource information sharing.In this paper,the characteristics of Ethernet network and MVB network are compared and analyzed,and the main features of vehicle level communication and train level communication schemes based on switched Ethernet train integrated bearing network are introduced.The comprehensive bearing train communication network based on switched Ethernet has significant advantages such as high bandwidth,high speed,high security,high stability,high compatibility,high flexibility and low cost as well.
