Abstract

The embodiment of the invention provides a network system for a rail train, and a rail train. The network system comprises a maintenance network which comprises two control vehicle switches which are arranged on a control vehicle of the rail train and are connected in series, wherein the maintenance network serves as a maintenance network of a communication control network of the rail train; an information network which comprises first equipment and second equipment which are arranged on a control vehicle of the rail train, wherein the first equipment is in communication connection with the two control vehicle switches so as to access the first equipment to the maintenance network in a double-path redundancy mode, and the second equipment is in communication connection with the first equipment; when at least one of the two control vehicle switches can work normally, called information flow can be called from the second equipment through the first equipment and the control vehicle switch which can work normally in the two control vehicle switches. The rail train comprises the network system. According to the embodiment of the invention, the technical problems that the information network operation of the rail train is liable to be interrupted and the disaster tolerance rate is low are solved.

Description

technical field [0001] The present application relates to the technical field of rail trains, in particular, to a network system for rail trains and rail trains. Background technique [0002] Most modern high-speed EMUs use a TCN network that conforms to the IEC61375 standard (TCN-Train Communication Network, train communication network) as their communication control network, and Ethernet as their maintenance network. With the improvement of train functions and the gradual introduction of indicators such as safety and comfort, the train is also equipped with a video surveillance information network and a freight information network. In order to meet the needs of transmitting large data volumes, these systems also use Ethernet. Therefore, on the high-speed EMU with the TCN architecture as the communication control network, there are multiple sets of Ethernet networks, and the train maintenance network and various information networks exist independently and operate separate...
