摘　　要：现代列车正朝着舒适智能的方向发展,传统的总线式技术已经不能满足大容量、高速率的通信需求,列车以太网成为列车控制网络的主要发展趋势。为评估列车以太网的网络运行健康状况,本文结合某型列车的网络拓扑,选取时延、抖动、丢包率与可利用带宽作为评估指标,提出了一种基于时间序列的多指标综合性能评估模型,对列车内各子系统和整体网络的性能进行评估。最后在实际列车中进行评估实验,实验证明,该方法能够有效反映以太网列车网络运行的健康状况。The modern train is developing towards to the direction of comfort and intelligence.The traditional bus technology has not been able to meet the communication requirements of large capacity and high speed.So the train Ethernet has become the main development trend of train control network.In order to evaluate the operation performance of train Ethernet,a multi index comprehensive performance evaluation model based on time series is proposed in the paper.On the basis of a train network topology,delay,jitter,packet loss rate and bandwidth was selected in the model to evaluate the performance of each subsystem and the whole network in the train.Finally,an evaluation experiment is carried out in a metro train running over Ethernet,which effectively reflects the health status of Ethernet train network.
