Embodiment 1

[0031] Embodiment 1 of the present invention provides a train network system, including: TCN and Ethernet (Ethernet, ETH for short).

[0032] TCN is used to transmit preset first train network data, and ETH is used to transmit preset second train network data.

[0033] In this embodiment, the TCN network is used to transmit the preset first train network data, and the Ethernet is used to transmit the preset second train network data. It can be seen that the train network system provided by this embodiment transmits the train network data separately, and the TCN network and the Ethernet network transmit a part of the train network data respectively. Compared with the prior art that only transmits the train network data through the TCN network, it can improve Network transmission bandwidth, thereby improving the efficiency of data transmission.

[0034] It should be noted that the preset first train network data and the preset second train network data are set as required, whic...

Embodiment 2

On the basis of the first embodiment, this embodiment provides another implementation manner of the train network system. Such as figure 1 and figure 2 As shown, the train network system provided in this embodiment may include:

[0039] TCN includes WTB and MVB, and Ethernet includes train backbone network (Ethernet Train Backbone, ETB for short) and train formation network (Ethernet Consist Network, ECN for short). ETB realizes Ethernet train-level communication, and ECN realizes Ethernet vehicle-level communication.

[0040] Each car of the train is provided with a first repeater module (Repeater, REP for short), a first Ethernet switch unit (Ethernet Switch Unit, ESU for short) and a networking devi...

Abstract

The invention provides a train network system. The train network system comprises a train communication network and Ethernet. The train communication network is used for transmitting first preset train network data, and the Ethernet is used for transmitting second preset train network data. By means of the train network system, the data transmission efficiency is improved.

Description

technical field [0001] The invention relates to the field of train network control, in particular to a train network system. Background technique [0002] At present, the network system of the high-speed EMU adopts a train communication network (Train Communication Network, TCN for short) topology. [0003] The TCN train bus is generally divided into two parts: the Wire Train Bus (WTB for short) and the Multifunction Vehicle Bus (MVB for short). Among them, WTB runs through the whole train and uses special shielded twisted pair cables for data transmission between different traction units, and to realize the interconnection of TCN networks between trains when trains are reconnected. MVB is a vehicle-level bus, which uses twisted-pair wires and is used for data transmission of each vehicle. The hierarchical structure of TCN trains is: each car has a WTB / MVB gateway node, and the gateway nodes between the cars are interconnected through WTB. In this way, each car can be cont...
