摘要
TCN(列车通信网络)和ARCNET(计算机网络辅助资源)是两种常用的列车通信网络。由于工作环境的特殊性,现代列车通信系统对通信网络的实时性和可靠性提出了非常严格的要求。利用OPNET软件,对TCN和ARCNET网络进行了建模仿真,对比分析了两者的实时性和可靠性。试验数据表明,TCN和ARCNET由于其结构不同,因而有着不同的特性。总体表现为:TCN具有较好的实时性,ARCNET具有较高的可靠性。因此,开发同时具有优良的实践性和可靠性的网络控制系统,是列车网络的主要研究方向。
TCN and ARCNET (auxiliary resource computer network) are two most common train communication net-works. A modem train communication system has strict re-quirements for the network because of the specificity of work- ing conditions. To analyze the real-time performance and re-liability property, in this paper a simulation of TCN and ARC-NET comunication networks is conducted by using the OPNET software. As the result shows, TCN and Arcnet have different characters because of their different structures, TCN has the preferable real-time performance, while ARCNET has better reliability property.
