摘　　要：利用网络仿真软件OPNET构建星型工业以太网列车通信网络(TCN)拓扑结构,并进行节点建模和业务建模.研究不同数据包大小、产生间隔和网络带宽,对以太网时延、数据包冲突和重传次数的影响.结果表明:通过增大数据包产生间隔、减小数据包的长度以及增加网络带宽都可以提高列车通信网络实时性.OPNET was used to build the topological structure of star industrial ethernet train communication network(TCN),and to model the nodes and services.The effects of packet size,generation interval and network bandwidth on Ethernet delay,packet collision and re-transmission times were studied.The results show that the real-time performance of train communication network can be improved by increasing packet generation interval,reducing packet length and increasing network bandwidth.
