Abstract

The invention discloses a train and a control network structure thereof. The train control network structure comprises a first Ethernet ring network topology structure which is used for transmitting first train control data and train information service data, and the train information service data comprises video data and service data of a train information service network; and the second Ethernet ring network topology structure is used for transmitting second train control data, and part of the second train control data comprises train control data redundant with the first train control data. According to the invention, a double-loop network topological structure is adopted between the vehicles, and two communication nodes are provided in each vehicle, so that the redundant transmission of the train control data and the train information service data is effectively realized, and the requirement of transmitting a large amount of data is well met, thereby greatly improving the train network operation efficiency.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a train and its control network structure. Background technique [0002] With the rapid development of train technology, the train control network system needs to transmit more and more data. [0003] The train control network system not only needs to transmit a large amount of train control data, but also needs to transmit a large amount of video data and service data of the train information service network. In the future, the informationized train will need greater bandwidth to meet the corresponding service requirements. [0004] However, the current train control network system generally uses a single bus network such as TCN (Train Communication Network, train communication network), which cannot better meet the requirements of transmitting large amounts of data, thereby reducing the operating efficiency of the train network.
