摘　　要：为了满足列车网络日益增长的数据传输需求,同时保证列车网络数据传输的可靠性和实时性,提高列车网络的灵活性和互联互通性,设计了一种总线型和交换型网络并存的列车网络控制系统,将2种网络优势互补,并可根据列车网络的实际情况,按照故障导向安全原则自动选择网络形式。搭建了实验室仿真试验平台,进行了MVB/WTB通信和TRDP(Train Real-time Data Protocol)通信之间的转换和列车控制逻辑的测试,并通过了400 km/h跨国互联互通动车组项目验证。试验证明,总线型和交换型网络并存的列车网络系统性能优异,能够为承载更加多样化的数据和拥有更加高效传输性能的列车网络控制系统提供重要支撑。In order to meet the increasing demand for data transmission,ensure the reliability and real-time of data transmission,and improve the flexibility and interconnectivity of the train network,a train network control system coexisting with bus and exchange network was designed.The advantages of the two networks were complementary,and the network form could be automatically selected according to the actual situation of the train network and the fault oriented safety principle.A laboratory simulation test platform was built,and the MVB/WTB communication,TRDP communication,the conversion between the two kinds of communication and the train control logic were tested,and the 400 km/h cross-country interconnectivity EMU project verification had been passed.The test results show that the designed network system has excellent performance and can provide important support for the train network control system with more diversified data and more efficient transmission performance.
