Abstract

The invention provides a mountain fire monitoring system and method based on infrared guidance and radar detection. In the mountain fire monitoring system and method, an infrared sensor and a radar detection device are fixed and integrated on the same rotating platform driven by a servo motor, the infrared sensor is used for finding an ignition point, the distance of the ignition point is measuredby the radar detection device, the ignition point is positioned, the radar detection device is used for monitoring the topography and vegetation coverage condition in the area near the ignition point, and combined with the wind speed and direction at the time, the fire risk classification and warning of transmission lines are realized. The functions of automatic finding, automatic positioning andautomatic alarm are realized, the line tripping accident rate caused by a mountain fire is reduced, and the capability of electric transmission lines to resist mountain fires disasters is improved.

Description

technical field [0001] The invention belongs to the technical field of power grid disaster prevention and mitigation, and relates to a mountain fire monitoring system and method based on infrared guidance and radar detection. Background technique [0002] With the continuous construction and development of the power grid, the society's demand for power supply reliability is getting higher and higher. The transmission line is one of the important components of the power grid, and its operating status determines the stability and safety of the entire power grid. However, the failure of transmission lines caused by wildfires has always seriously affected the safe and stable operation of transmission lines. This is mainly due to the decrease in the insulation strength of transmission lines caused by wildfires, resulting in the breakdown of air. How to effectively prevent and reduce the hazards of wildfires to transmission channels, reduce power grid failures and blackouts, impr...
