Satellite-borne fire information multichannel publishing system

Abstract

A satellite-borne fire information multichannel publishing system comprises a fire point detection sensor used for acquiring fire point imaging information and communicating with a short message system and a whole satellite SRTU; the short message system communicates with the fire point detection sensor and the ground command terminal; the whole satellite SRTU communicates with the fire point detection sensor and the ground command terminal; the intelligent processing center control unit is used for determining spatial geographic information elements, sending the spatial geographic information elements to the fire point detection sensor, receiving remote sensing measurement information output by the fire point detection sensor, and performing field elimination, calculation and storage on the received remote sensing measurement information; the intelligent processing center control unit issues fire point information according to a ground instruction; and the ground command terminal is used for receiving the image data and / or the fire point information and issuing the image data and / or the fire point information.

Description

technical field [0001] The invention relates to a multi-channel release system for satellite-borne fire information, which belongs to the technical field of intelligent remote sensing satellites. Background technique [0002] The current fire prevention and monitoring methods include: artificial fire prevention, high-altitude inspection by aircraft, and satellite remote sensing. [0003] (1) Artificial fire protection: Common methods include building watchtowers, manual inspections, and establishing ground monitoring networks. Disadvantages of this method: it is difficult to make a comprehensive inspection, the investment of manpower and material resources is large, the efficiency is low, the rate of false positives is high, and the error is large. [0004] (2) Aircraft high-altitude patrol: the disadvantages of this method: large capital investment, expensive, complicated work, and the phenomenon of underreporting also exists. [0005] (3) Satellite remote sensing: the ad...

Problems solved by technology

Disadvantages of this method: it is difficult to make a comprehensive inspection, the investment of manpower and material resources is large, the efficiency is low, the rate of false positives is high, and the error is large

[0004] (2) Aircraft high-altitude patrol: the disadvantages of this method: large capital investment, high price, complicated work, and the phenomenon of underreporting also exists

[0011] 1) The above-mentioned satellite-loaded fire surveillance cameras cannot independently observe fires in orbit, and need to transmit the images to the ground for processing, and the real-time performance is poor

[0012] 2) Satellite storage resources are limited, and on-orbit image information storage cannot be realized;

[0013] 3) The real-time processing of spaceborne images cannot be performed, and the distribution and storage of fire point information feature data cannot be realized;

[0014] 4) Feature data storage cannot be realized, sensor self-calibration and false target removal cannot be realized

[0015] 5) There is no real-time storage of characteristic data, and it is impossible to provide timely early warning of global target fire points
