The invention provides a multiple unit train communication network topology framework based on Ethernet. A multiple unit train adopts a form of 8-carriage consist, and the 8-carriage consist is divided into two traction units. The multiple unit train communication network topology framework is characterized in that train dynamic configuration between the two traction units is realized by adoptingEthernet Train Backbone (ETB), wherein the ETB is provided with four Ethernet Train Backbone nodes (ETBNs); in each of the traction units, two Ethernet repeaters (EREPs) are connected in series between the corresponding two ETBNs; Ethernet Consist Network (ECN) inside the traction units is provided with Ethernet Consist Network nodes (ECNNs); the ECNNs in each of the traction units are connected in series and then connected to the corresponding ETBNs; and in each carriage, the corresponding single ECNN is used as the center to be connected with subsystem equipment. The whole train adopts the multiple unit train communication network topology framework based on Ethernet, thereby reducing the network load rate, and simplifying the network communication design. Meanwhile, the safety and reliability of a train network are ensured through redundancy design.

    本发明提供一种基于以太网的动车组列车通信网络拓扑架构,动车组列车采用八辆编组形式,八辆编组分为两个牵引单元,其特征在于:两个牵引单元之间采用列车级骨干网ETB实现列车动态配置,所述列车级骨干网ETB上设置四个列车级骨干网节点ETBN,每个牵引单元内的两个列车级骨干网节点ETBN之间串联两个以太网中继器EREP,牵引单元内部的车辆编组以太网ECN上设置车辆编组以太网节点ECNN,每个牵引单元内部的车辆编组以太网节点ECNN串联后与列车级骨干网节点ETBN连接,每个车厢内部以单个车辆编组以太网节点ECNN为中心连接各子系统设备。全列车采用以太网的动车组列车网络架构,降低网络负载率,简化了网络通信设计,同时通过冗余设计保证列车网络的安全可靠性。
