摘要
阐述了基于工业以太网的列车网络控制系统关键技术,对网络系统拓扑结构、实时性和可靠性进行了研究,基于实际工程项目,采用了交换式以太网、环形拓扑结构以及关键设备冗余的设计方案,完成了实时数据通信协议的开发。试验证明,该网络系统实时性与可靠性满足标准和实际运用要求。
The paper expounds the key technologies of the train network control system based on industrial ethernet, focusing on the topology structure, instantaneity and reliability of the network system. Combining with actual engineering projects, we developed the real-time data communication protocol by adopting the design schemes of the switched ethernet, ring topology and key equipment redundancy. The test shows that the instantaneity and reliability of the network system meet the requirements of standards and practical application.
