摘　　要：通信网络是列车的神经系统。它把所有的控制器和传感器等设备连接起来,实现信息采集和控制。为了研究列车通信网络的安全性和可靠性,分析影响网络性能的原因,同时优化网络参数,利用网络仿真软件OPNET搭建了基于CAN总线的列车通信网络仿真模型,研究了应答错误和误码率对网络负载、吞吐量、节点状态等方面的影响。结合实际列车通信网络结构,通过该仿真模型得到相应的仿真结果,今后可为实际列车的通信网络性能分析提供参考。Communication network is the nervous system of train vehicles, in which all of the controllers, sensors and other devices are connected to collect information and control the train. In order to ensure the security and reliability of train vehicle communication network, the influential factors of network performance shall be analyzed, and the network parameters be optimized. In this paper, OPNET network simulation software is used to build a train commu- nication on the basis of CAN Bus network, the response of error, error rate on network load, throughput and node- state are studied. Applied in the actual train communication network structure, the model simulation result could match the actual system, it is clear that this model can be used to achieve the goal of actual communication network optimi- zation and control algorithm.
