Train network, communication method, train, electronic equipment and storage medium

Abstract

The invention provides a train network, a communication method, a train, electronic equipment and a storage medium. The train network comprises a train-level backbone network, an internal Ethernet and a vehicle-level Ethernet; the train-level backbone network comprises ETBN switches configured by train subunits, and the ETBN switches are connected through a bus type topological structure; the vehicle-level Ethernet comprises an ECNN switch configured in a compartment and equipment in the compartment; the ECNN switches are connected in a ring topology structure, and the equipment is connected with the ECNN switches through Ethernet interfaces; the central control unit is connected with the ECNN switch; the ETBN switch in the train-level backbone network is connected with any ECNN switch in the vehicle-level Ethernet through an internal Ethernet; the IP addresses of all devices in the same subunit are different; IP addresses of devices of the same type at corresponding positions in different subunits are the same. The train information transmission speed and stability can be improved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a train network, a communication method, a train, electronic equipment and a storage medium. Background technique [0002] At present, most train network control systems adopt the Train Communication Network (TCN for short), and the train level adopts the wire train bus (WTB for short) to realize cross-unit and cross-group train-level communication, and undertake reconnection. For the data transmission function, the vehicle level adopts the Multifunction Vehicle Bus (MVB) bus to realize the internal communication and control of the vehicle. [0003] However, in the current train communication network, the amount of data communication continues to increase, and the traditional train network control system has the problem of small bandwidth. The diagnostic equipment based on the TCN network is difficult to meet the needs of high-speed uploading and downloading files, resultin...

Problems solved by technology

[0003] However, in the current train communication network, the amount of data communication continues to increase, and the traditional train network control system has the problem of small bandwidth. The diagnostic equipment based on the TCN network is difficult to meet the needs of high-speed uploading and downloading files, resulting in a decrease in the efficiency of train diagnosis and maintenance.
