Multi-satellite multi-frequency band-based multi-architecture emergency guarantee system

Abstract

The invention discloses a multi-satellite multi-frequency band-based multi-architecture emergency guarantee system. The system is composed of three parts including a near-ground assimilation forecastcenter for realizing near-ground information assimilation, a monitoring subsystem for realizing field information analysis and supervision, and a multi-source data communication system for guaranteeing the rescue communication quality. Firstly, the near-ground assimilation forecast center takes a Beidou satellite group, a Tiantong satellite and a communication satellite as information sources, utilizes a WRF-EnSRF assimilation system to carry out assimilation on collected weather, geographical and disaster situation information, and realizes information publishing through an early warning information publishing network; secondly, the monitoring subsystem performs extraction analysis and fusion on positioning information, weather parameters, environment distribution and other data obtainedon site, and sets a bridge in the assimilation forecast center and the multi-source data communication system to realize real-time acquisition and supervision of the information; and finally, the multi-source data communication module realizes transmission of audio, video and text information by utilizing multiple communication means including a broadcast, a radar and a local area network.

Description

technical field [0001] The invention belongs to the field of satellite emergency support, in particular to a multi-architecture emergency support system based on multiple satellites and multiple frequency bands. Background technique [0002] In recent years, major social disasters such as mine collapses, floods, and earthquakes have occurred continuously, repeatedly testing the public security system and social security capabilities of the entire society. When these events occur, communication is one of the most critical links in the social security system. , has been included in the national special emergency support work construction plan. At present, as an organized emergency support system, whether the best communication tools can be selected, real-time information transmission and on-site rescue operations can be interlocked is the key to ensuring the timely delivery of ambulance. [0003] The current communication methods mainly include optical fiber communication, mi...
