Embodiment Construction

[0029] The present invention will be further described below in conjunction with embodiment.

[0030] (1) Collect the data of all transmission line towers in the target area, including the longitude and latitude coordinates of the towers, the name of the line where they are located, the voltage level and other information;

[0031] (2), divide the target area into m sub-area grids w with a side length of 6km 1 (x 1 ,x 2 ,y 1 ,y 2 ), w 2 (x 2 ,x 3 ,y 2 ,y 3 ),...w m×n (x m ,x m+1 ,y n ,y n+1 ), where w 1 、w 2 ,...,w mn is the 1st to m×n sub-regions, each sub-region is determined by its maximum and minimum latitude and longitude, x m 、x m+1 respectively for the subregion w mn The minimum and maximum longitude, y n 、y n+1 Respectively for the sub-region w mn The minimum and maximum latitude of . w 1 、w 2 ,...,w mn according to x 1 、x 2 ,...,x m+1 with y 1 、y 2 ,...,y n+1 Sequentially numbered from small to large, and stored in sequence;

Abstract

The invention discloses a method for transmission line tower forest fire alarming and positioning based on a region block search strategy. The method includes the following steps that basic data are collected; data of all transmission line towers in a target region are collected and comprise tower longitude and latitude coordinates, the names of lines where the transmission line towers are located, voltage classes and other information; sub-region division is conducted on all the transmission line towers; the data of all the transmission line towers are divided into blocks; fire point coordinates monitored by a transmission line forest fire satellite monitoring system are received in real time; sub-regions where fire points are located are judged; the towers of the sub-regions where the fire points are located are found. The block search strategy is provided, the region of the transmission line towers is divided into multiple sub-regions with the fixed size, only the sub-regions where the fire points are located or the towers in the sub-regions adjacent to the sub-regions are found and calculated, search for the rest of a large number of sub-regions is avoided, the calculation speed can be greatly increased, time waste caused by fire point alarming calculation is reduced, and forest fire prevention efficiency of a power grid is improved.

Description

technical field [0001] The invention belongs to the technical field of disaster prevention and mitigation for power system transmission lines, and in particular relates to a transmission line tower fire alarm positioning method based on an area block search strategy. Background technique [0002] Most of the wildfires near the transmission lines are shrub and thatch fires, which burn quickly. If they are not handled in time, they can easily spread to the bottom of the line and cause the line to trip. When using the transmission line mountain fire satellite monitoring system to monitor mountain fires, the alarms caused by the fire point to the line should be quickly calculated to gain valuable time for on-site disposal measures. However, the transmission lines in each province are intricate, with hundreds of thousands to millions of towers, and during the period of high wildfires, some provinces have hundreds of fire points in a day. The calculation of the alarm information ...
