Research on transmission line fire monitoring technology based on remote sensing satellite data

In order to meet the needs of transmission line fire monitoring, the geographic information system of the transmission line is established, and the visualization functions of disaster information such as position display and image superposition are realized. At the same time, in order to obtain disaster information data quickly and process it into orthogonal projection data containing geographic coordinates information. This paper studies the ignition point identification, and uses the least -squares estimation method to fit the relationship between the brightness threshold and the key influencing parameters in the form of a linear equation, and proposes a method for determining the location of the ignition point and a method for determining the distance between the ignition point and the transmission line. The experimental results show that the proposed method can timely monitor the transmission line fire disaster, and the monitoring has high reliability, high accuracy in fire identification and location, and successfully improves the overall effect.
