摘要
基于以太网技术的列车通信网络为研究对象,从列车通信网络架构设计及功能集成设计2方面进行了应用性研究。首先,对基于以太网的列车通信网络构建形式进行了探讨,并从不同维度对各种网络拓扑形式进行了可靠性分析;在此基础上,进一步讨论了多业务融合网络技术在城市轨道交通车辆中的实现形式;最后,通过具体的应用实例验证了文中所设计的适应多业务融合的列车以太网网络拓扑的可行性。实测表明,该网络系统模型稳定可靠,具有较强的网络兼容性以及良好的通信性能,能够有效提升网络控制系统应用效率。
In this paper,train communication network based on Ethernet technology is taken as the research object,and the applied research is carried out from two aspects of train communication network architecture design and functional integration design.First of all,kinds of train network topology scheme based on Ethernet was designed in this paper.The realization form of the network technology for train multi-service integration was described from the perspective of applications,and reliability analysis was conducted for the overall train network topology from different dimensions.Finally,with a concrete application instance,the feasibility of the designed train Ethernet network topology adapted to multi-service integration was validated.The testing results showed that the proposed network system model had strong ability of compatibility and good communication performance,which was stable and reliable and could effectively enhance the application efficiency of the network control system.
