Abstract

The invention discloses a geosynchronous satellite wide area power grid wildfire remote sensing signal receiving device comprising a pedestal, a stand column and a receiving pot. A feed source is installed in front of the spherical reflection surface of the receiving pot via a support. The stand column is arranged on the pedestal via a rotating mechanism and can rotate around the vertical axis. The receiving port is hinged on the stand column round the horizontal axis. The receiving device also comprises a rotating driving assembly which is used for driving the stand column to rotate and a pitching driving assembly which is used for driving the receiving pot to perform pitching movement. The geosynchronous satellite wide area power grid wildfire remote sensing signal receiving device has advantages that a power grid wildfire geosynchronous satellite wide area weak signal can be accurately received, monitoring range is wide, and detection real-time performance and reliability are high.

Description

technical field [0001] The invention relates to the technical field of disaster prevention and mitigation for power system transmission lines, in particular to a remote sensing signal receiving device for mountain fires in a synchronous satellite wide-area power grid. Background technique [0002] Power grid wildfire is one of the main disasters that endanger the safety of power grid transmission. It can easily cause line trips, and even cause the collapse of large power grids in severe cases. Power grid wildfires occur in most parts of our country, regardless of region or season, as long as the three elements of combustion are present, they will occur. It covers a wide area, covers a long time, and affects a large range, which is enough to make it a social disaster. Only a small number of wildfires can be found by using conventional ground monitoring devices or manual line inspection, and the investment cost is huge. [0003] The use of satellites to monitor wildfires in ...
