Method for constructing vehicular wireless network of railway freight train

Abstract

The invention discloses a method for constructing a vehicular network of a railway freight train. The method can comprise embodiments of all parts of the network and is used for providing an intelligent infrastructure for the freight train. One embodiment can comprise control devices, multiple information collecting devices and a power supplying device, wherein the control devices are arranged on a locomotive/vehicle, the multiple information collecting devices are arranged on the locomotive/vehicle, and the power supplying device is mounted on the vehicle; the control devices are used for enabling node interconnection and vehicle external communication and providing network service, data transmission, data processing and data storage; the information collecting devices are used for acquiring and monitoring data of vehicle components; the vehicular control devices are equipped with wireless supplying devices which are used for supplying power to the information collecting devices. One embodiment can comprise a light energy recovered power supplying device, and a light source can be natural light or laser or the like. Vehicular network support nodes are dynamically adjusted, and control nodes in the same train marshalling can construct a logic-independent network.

Description

technical field [0001] The invention belongs to the technical field of electronic communication, mainly relates to the construction, management and application of the on-board network of railway freight trains, and is an infrastructure for realizing the intelligence of railway freight trains. Background technique [0002] At present, information technology has been widely used in railway locomotives and passenger cars, but because some technologies and freight vehicles have no power restrictions, on-board monitoring equipment cannot be installed, and the safety monitoring and other information monitoring and analysis of freight vehicles mainly rely on the ground monitoring and ground systems. With the continuous development of Internet of Things technology, the technical limitations of on-board safety monitoring of freight vehicles have been solved. The on-board network is the basis for realizing on-board safety monitoring. For railway passenger cars, wired connections are ...

AI Technical Summary

Problems solved by technology

[0003] However, there are still the following prominent problems in the construction of the on-board network of railway freight trains: 1. The train marshalling is often adjusted, and the wired connection method is not suitable for the construction of the on-board network of freight trains; 2. There is a lack of network interconnection facilities between locomotives and train vehicles. Networking and service capabilities are limited; 3. Freight train vehicles generally do not have separate power supply facilities, and need self-powered energy to supply data acquisition equipment and network interconnection equipment; 4. The operating environment of freight trains is complex, and in order to ensure reliability, on-board Various special designs for information devices
