Forest fire monitoring system and method based on high-resolution remote sensing satellite

Abstract

The invention provides a forest fire monitoring system based on a high-resolution remote sensing satellite. The forest fire monitoring system comprises a bottom shell, a stand column, a driving frame,a top shell, retraction rods, a bearing, a driving gear, a transmission shaft, a transmission gear, a solar panel, a sealing ring, a circuit box, a one-way valve and a pin. A hidden cavity is formedin the center of the top face of the bottom shell. The stand column extends out of the bottom face of the hidden cavity, and the circuit box is mounted on the top end of the stand column. A center ring of the driving frame is in pin joint with the bottom end of the stand column, liquid in the bottom shell liquid storage cavity expands after being heated and then drives the driving frame to move upwards, and thus the circuit box is driven to be exposed upwards from the hidden cavity. The bottom ends of the outer side guide sections of the retraction rods are in threaded connection with the fourcorners of the bottom shell, the inner side sections of the retraction rods are installed in a pressing cavity of the top shell, and the pressing cavity of the top shell communicates with the liquidstorage cavity of the top shell; a transmission groove is formed in the bottom face of the top shell, the driving gear is installed in the transmission groove through the transmission shaft and the bearing, and the transmission groove is meshed with a vertical rack on the outer side section of the retraction rods. The transmission shaft is further in pin joint with the transmission gear which is meshed with a horizontal rack on the bottom face of the solar panel.

Description

technical field [0001] The invention relates to a monitoring system, in particular to a forest fire monitoring system based on high-resolution remote sensing satellites. Background technique [0002] Forest fire is one of the most serious types of disasters affecting forest ecosystems. On average, hundreds of thousands of forest fires occur every year in the world, and the affected area of ​​forests is hundreds of hectares, accounting for about 0.1% of the global forest coverage. Forest fires not only cause huge economic losses to forestry resources, but also change the carbon cycle process and carbon distribution pattern of the entire ecosystem, disrupting the balance of the global ecosystem. At the same time, forest fires release a large amount of harmful substances, which not only aggravates climate change and air pollution in some areas, but also poses a great threat to the lives and property of surrounding residents. As climate change continues to intensify, affected ...
