Embodiment Construction

[0026] The present application is based on the tree growth prediction line channel safety analysis method specifically includes the following steps:

[0027] 1. Use laser radar, high-resolution digital camera, and hyperspectral instrument to collect point cloud data, high-resolution images and hyperspectral data of transmission line channels and surrounding features;

[0028] 2. Use the point cloud data to classify the ground objects, and divide the point cloud data into four categories: transmission line D1, transmission tower D2, tree D3, and building D4;

[0029] 3. Combining tree point cloud data D3, high-resolution images and hyperspectral data, divide the data into individual trees and establish a tree database for transmission line channels. The database includes tree number A, type C, tree crown position range F, and tree crown height G , growth factor S, growth coefficient Z, safety hazard level Y;

[0030] 3.1 Determine growth factors based on hyperspectral data, an...

Abstract

The invention discloses a line channel safety analysis method based on tree growth prediction, and relates to the field of power transmission safety operation and maintenance. According to the method,tree point cloud data, high-resolution images and hyperspectral data are combined; a power transmission line channel tree database is established, the distance between a tree and a power line is judged according to the crown position range, the crown height and the growth coefficient, the potential safety hazard level of the tree is calculated according to the distance, and when the potential safety hazard level is marked as emergency, power transmission line operation and maintenance personnel are reminded to conduct on-site investigation and treatment n days before corresponding time nodes.The patrol workload of operation and maintenance personnel of the power transmission line can be greatly reduced, the patrol efficiency is effectively improved, the personal safety risk is reduced, and finally the operation and maintenance cost of the power transmission line is reduced.

Description

technical field [0001] The invention relates to the field of power transmission safety operation and maintenance, and more specifically, the invention relates to a method for analyzing the safety of line passages based on tree growth prediction. Background technique [0002] With the rapid development of the national economy, the national demand for electricity has increased, and the distribution of transmission lines in the wilderness has become increasingly widespread. Because transmission lines have the characteristics of long line spans, high safety and reliability requirements, and wide coverage areas, the safety maintenance of transmission lines has become a very heavy task. Failure to maintain and inspect transmission lines in time will lead to line trips or human and animal casualties caused by tree interference in the downlink passage of transmission lines, and even cause power outages, and even fires in severe cases. These safety incidents demonstrate the need for...
