| 摘 要： | 针对传统列车通信网络(Train Communication Network,TCN)难以满足下一代列车通信网络的带宽需求,提出了基于交换式以太网的TCN解决方案,建立了基于交换式以太网的列车通信网络拓扑结构和通信协议栈模型。在满足网络强实时性方面,进行了相关改进。然后通过VxWorks试验平台进行试验验证,结论是这种新方案在较大提高网络带宽的同时,能保证网络的确定性和实时性,能很好地满足传统TCN网络传输数据的要求,证明了基于交换式以太网列车通信网络代替TCN的可行性。 |

| Abstract: | Because traditional TCN is increasingly difficult to meet bandwidth requirements of the next generation of train communication network,this paper presents a solution of train communication network based on switched Ethernet,and builts the model of the train communication network topology based on switched Ethernet and communication protocol stack.In order to meet the hard real-time need,we propose some improvements.Then we carry out experimental verification with VxWorks test platform.The conclusion is that this new program can improve the network bandwidth,ensure determinism and real-time of network and satisfy the traditional requirements of network communication,which proves that train communication network based on switched Ethernet can take the place of TCN. |
