Train-ground synergetic distributed network management system and method for high-speed rail wide-band communication system

Abstract

The invention discloses a train-ground synergetic distributed network management system and method for a high-speed rail wide-band communication system. The train-ground synergetic distributed network management system for the high-speed rail wide-band communication system comprises an in-vehicle network management subsystem, a ground data relay station, a ground network management center and a management client, wherein the in-vehicle network management subsystem comprises a function management agent terminal, a management analysis processing module, a local database, a management southbound interface module and a management northbound interface module. According to the train-ground synergetic distributed network management system and method disclosed by the invention, aiming at the characteristic of the quick movement of a high-speed rail train, wireless bandwidth occupied by train-ground management information flow is reduced, and the high-efficiency reasonable management of the high-speed rail wide-band communication system is realized.

Description

technical field [0001] The invention relates to a network management system and method, in particular to a network management system and method suitable for high-speed railway broadband communication systems. Background technique [0002] With the continuous development of my country's high-speed railway construction, high-speed trains have become an important means of transportation for passengers to travel long distances. At the same time, passengers have increasingly urgent needs for high-quality communication and digital entertainment services on high-speed trains. At present, foreign countries combine satellite technology, GPRS (General Packet Radio Service) and UMTS (Universal Mobile Telecommunications System) technology with WiFi wireless network to provide uninterrupted wireless broadband Internet connection on cross-border trains with a speed of up to 300km / h; and Someone proposes a train operation control network based on WiMAX (Global Interoperability for Microwav...

Problems solved by technology

At the same time, due to the Doppler frequency shift and fast switching caused by the high-speed movement of the train, there may be a large bit error rate in the communication link between the train and the ground, and the retransmission of information may even lead to the interruption of the communication link, which affects the transmission. time delay
