Train backbone network and train communication network

Abstract

The invention relates to a train backbone network and a train communication network. The train backbone network includes a plurality of wireless backbone nodes; two ends of each train section are respectively provided with a wireless backbone network node; the plurality of wireless backbone nodes comprise a top node; and when train initial running operation is carried out, the top node is configured to acquire the location information of the other wireless backbone nodes through a wireless communication network formed by the plurality of wireless backbone nodes and complete train initial running operation based on the location information of the top node itself. The train backbone network is realized through adopting wireless broadband technologies, and therefore, physical cables can be omitted, and poor contact of insertion pins of a connector, which is caused by repeated plugging and pulling out, can be effectively solved, the connection mode of the train backbone network can be simplified, the communication quality of the backbone network can be effectively ensured, and the reliability of the backbone network can be improved.

Description

technical field [0001] The invention relates to the technical field of train communication networks, in particular to a train backbone network and a train communication network. Background technique [0002] The IEC61375 international standard divides the train communication network (TrainCommunicationNetwork, referred to as TCN) into two levels, that is, the backbone network (TrainBackbone) on the top layer and the formation network (ConsistNetwork) on the bottom layer. [0003] At present, the train backbone network is mainly realized by bus technology, and the commonly used buses in the train backbone network include the Wire Train Bus (WTB for short) and the Multifunction Vehicle Bus (Multifunction Vehicle Bus, MVB for short). Among them, WTB is mainly used on trains with dynamic formation requirements (such as locomotives and bullet trains, etc.), while MVB is mainly used on trains with fixed formation characteristics (such as bullet trains). [0004] The process of in...

Problems solved by technology

For trains with dynamic marshalling requirements, when the car coupling and uncoupling operations reach a certain number of times, multiple plugging and unplugging will lead to poor contact of the connector pins
