Embodiment 1

[0018] (1) Use conventional methods to build a GIS platform;

[0019] (2) Using the GIS platform built in step (1), use conventional methods to collect distribution data of power grid transmission lines, actual mountain fire occurrence records and reported data, satellite hotspot data, daily meteorological data during periods of high mountain fire occurrence over the years, and digital elevation Model and topographic map base map data, industrial and agricultural production laws and people's traditional living customs data, transmission line channel corridor vegetation type data and transmission line channel corridor vegetation coverage data, including the area where the power grid transmission line fire spot is located fire point data;

[0020] (3) Using the GIS platform built in step (1), according to the integral multiple of 10 years as a counting period, use conventional methods to collect the data collected in step (2) in the area where the power grid transmission line fi...

Embodiment 2

[0025] Steps (1) to (3) are the same as in Example 1;

[0026] (4) Use conventional methods to divide the area where the fire points of the power grid transmission lines are located into grid-like areas. Customize grid size to 10km 2 / grid. Then calculate the occurrence data of wildfires and fire points in different periods of the power grid transmission lines in the grid, and obtain the data of wildfires and fires in different periods of time. Taking the obtained wildfire fire point data in different periods as the standard value, and according to the fire point data collected in the above step (2) where the mountain fire fire point of the power grid transmission line to be mapped is located, the urban industrial fire, urban hotspot effect, Non-mountain fire strong reflectivity satellite hotspot information, and interference noise correction for mountain fire data;

[0027] Steps (5)-(6) are the same as in Example 1.

Abstract

The invention provides a GIS (Geographic Information System) platform-based method for drawing a distribution map of mountain fire points of a power grid electric transmission line. The method comprises the following steps of (1) setting up a GIS platform; (2) collecting the fire point data of regions at which power grid electric transmission line mountain fire points to be drawn are located; (3) carrying out periodical subsection statistic and periodical classified statistic; (4) carrying out interference noisy point correction; (5) carrying out spatial interpolation; and (6) correcting the distribution map of the mountain fire points of the electric transmission line. The method has advantages that (1) the distribution map of the mountain fire points of the power grid electric transmission line can be conveniently selected by each region for use; (2) the practicability of the distribution map of the mountain fire points of the power grid electric transmission line is improved; (3) a method for correcting the distribution map of the mountain fire points of the power grid electric transmission line is defined; (4) the prevention and reduction of disasters of a power system are facilitated; (5) the influence on grade classification of degree of severity of the mountain fire points of the power grid electric transmission line caused by interference noisy points is facilitated to be judged.

Description

technical field [0001] The invention belongs to the technical field of electrical engineering, and in particular relates to a method for drawing a distribution map of mountain fire points of power grid transmission lines based on a GIS (English full name is "Geographic Information System" abbreviation, Chinese translation is "Geographic Information System") platform. Background technique [0002] In recent years, wildfires have caused more and more damage to power grid transmission lines. Therefore, it is very important to strengthen the monitoring and pre-control of wildfires on power grid transmission lines. The most important prerequisite for strengthening monitoring and pre-control is to map the power grid transmission Distribution map of forest fire points along the line. However, the frequent occurrence of wildfires is closely related to the laws of local industrial and agricultural production, the traditional living customs of the people, meteorological characteristic...
