Abstract

The invention discloses a train network marshalling method, device and system. The method comprises the following steps: obtaining a plurality of marshalling units according to train requirement length, wherein each marshalling unit comprises at least one carriage; setting a marshalling ring network and a backbone network node for each marshalling unit, wherein the marshalling ring network is used for connecting the at least one carriage in each marshalling unit, and the backbone network node is used for sending carriage information of each marshalling unit to the other marshalling units; and combining the plurality of marshalling units to obtain a train network. The train network marshalling method, device and system solve the technical problem of poor flexibility of train network marshalling since each carriage needs to be provided with a train communication network gateway in train network marshalling in the prior art.

Description

technical field [0001] The invention relates to the field of rail vehicles, in particular to a train network marshalling method, device and system. Background technique [0002] In the prior art, in the flexible marshalling of the train network, a train communication network (TCN, TrainCommunication Network) gateway needs to be set in each vehicle, so that each vehicle forms a network of its own. When changing, the TCN gateway can automatically address the nodes in the corresponding order through the initial operation, and re-allocate the address for the vehicle to determine the position of the vehicle relative to the main node, and notify all nodes of the direction of the train, so as to realize the flexibility of the train network marshalling. However, since a TCN gateway needs to be installed in each vehicle, the cost is high and the flexibility is poor. [0003] Aiming at the problem that train network marshalling in the prior art needs to set a train communication net...
