The invention relates to a train-level control network. The train-level control network comprises a first train control network and a second train control network, wherein the first train control network transmits the real-time control information used for controlling each vehicle-mounted control subsystem to a first switching node device of each carriage, the second train control network transmits the control information to a second switching node device of each carriage and receives the non-real-time media information of each vehicle-mounted media information acquisition subsystem from eachsecond switching node device, and the first train control network and the second train control network form two separated Ethernet ring networks. The train control network has a multi-network integration function, multiple redundancy measures are designed at the same time, compared with other Ethernet networks, reliability is greatly improved, in addition, the invention further provides a corresponding vehicle-level control network, a carriage and a train.
本发明涉及一种列车级控制网络,列车级控制网络包括第一列车控制网络和第二列车控制网络,第一列车控制网络向各个车厢的第一交换节点设备传输用于控制各个车载控制子系统的实时的控制信息;第二列车控制网络向各个车厢的第二交换节点设备传输控制信息并且从各个第二交换节点设备接收各个车载媒体信息采集子系统的非实时的媒体信息;第一列车控制网络和第二列车控制网络构成为两个分离的以太网环网。本发明的列车控制网络具备多网融合功能,同时设计了多项冗余措施,比较其他以太网网络,可靠性得到大幅提升。此外本发明还提供相应的车辆级控制网络、车厢和列车。
