Embodiment Construction

[0019] Such as figure 1 As shown, the present invention builds a tree barrier monitoring system for power transmission corridors based on aviation remote sensing, relies on the airborne LiDAR (2) carried by the aviation vehicle (1) to carry out multiple echo detection of trees on the ground surface in a wide area, and passes the detection results through The communication module (3) transmits the data processing module (4) to the ground through the analysis and calculation of the surface digital elevation model (DEM) and the canopy surface digital model (DSM) to obtain the regional tree height distribution data, and then the regional tree height distribution data Input grid transmission GIS overlay analysis module (5) to perform overlay analysis to obtain the distance between transmission corridor trees and transmission lines, and input the overlay analysis results into data management module (6) to realize the time series change of the distance between transmission corridor tr...

Abstract

The invention discloses a transmission corridor tree barrier monitoring system based on aerial remote sensing. The system relies on an airborne LiDAR (2) carried by an aerial vehicle (1) to carry outmultiple echo detection on surface trees and transmits the detection result to a ground data processing module (4) through a communication module (3), and a surface digital elevation model (DEM) and acanopy surface digital model (DSM) carries out analyzing and calculating to acquire regional tree height distribution data. The tree height data are input into a grid transmission GIS overlay analysis module (5) for overlay analysis to acquire the distance between trees in a transmission corridor and a transmission line. The overlay analysis result is input into a data management module (6) to implement data management of the distance between trees in the transmission corridor and the transmission line, wherein the distance changes with a time series. Comparing with the set early warning value of the safety distance of the transmission line is carried out, and if the early warning value is reached, a warning signal is sent immediately. A technical support is provided for the clearing of tree barriers in the transmission corridor.

Description

technical field [0001] The invention relates to the field of power transmission corridor monitoring, in particular to a power transmission corridor tree barrier monitoring system based on aerial remote sensing. Background technique [0002] Transmission lines are the lifeblood of energy transportation that carries the needs of national production and life, and are an important part of the power grid system. The safe and stable operation of transmission lines is particularly important for national production and stable operation of the power grid. [0003] With the improvement of the design and construction level of transmission lines, the installation of anti-bird thorns, lightning arresters, online monitoring and other facilities, and the strengthening of people's awareness of greening and forest protection, trees in transmission corridors have gradually become a major problem affecting the safe operation of transmission lines. The threat of trees in the transmission corrid...
