Embodiment 1

[0048] An intelligent statistical method for important intersections and spans of transmission lines based on a hypergraph platform, comprising the following steps:

[0049] S1: Obtain the point cloud data of the transmission line with three-dimensional coordinates;

[0050] S2: According to the point cloud data containing three-dimensional coordinates, extract the coordinates of transmission line towers;

[0051] S3: According to the coordinates of transmission line towers, publish map services and data services on the SuperMap platform;

[0052] S4: Obtain the coordinates of the tower in the data service;

[0053] S5: According to the coordinates of the tower, display the line drawing of each section of the tower section of the transmission line on the map;

[0054] S6: Perform data comparison, automatically count the information of the crossed objects in each section of the tower section, and output it as a table.

[0055] In step S1, the original point cloud data and IMU ...

Embodiment 2

[0076] An intelligent statistical method for important intersections and crossings of transmission lines based on the HyperMap platform, through unmanned aerial vehicle equipped with laser radar, ground-based radar, vehicle-mounted radar and other technical means, conduct three-dimensional high-precision laser modeling of transmission lines, and obtain laser point clouds of transmission lines data. High-precision lidar uses the principle of laser ranging and photogrammetry to quickly obtain three-dimensional data on the surface of large-scale transmission lines and channels, and can quickly generate digital elevation models, digital surface models and digital orthophotos, and restore lines and corridors with high precision.

[0077] After the lidar outdoor modeling work is completed, the point cloud data containing coordinates is obtained, and the spatial three-dimensional laser point cloud model corresponding to the actual tower spatial position is established. The first posi...

Abstract

The invention provides a hypergraph platform-based intelligent statistical method for the important crossing of a power transmission line. According to the method, the method comprises the steps of firstly obtaining point cloud data containing three-dimensional coordinates of a power transmission line; extracting power transmission line tower coordinates according to the point cloud data; publishing a map service and a data service in a hypergraph platform according to the tower coordinates; acquiring tower coordinates in the data service; according to the tower coordinates, lines drawn in each tower section of the power transmission line are displayed on a map; and finally, performing data comparison, automatically counting the information of the spanned object in each tower section, andoutputting a result as a table. According to the invention, intelligent statistics of important crossing section information of the power transmission line is realized. Compared with the prior art that statistics and maintenance of important crossing section information of the power transmission line are completed manually. The method greatly improves the working timeliness and accuracy, reduces the manual workload, and improves the intelligence and automation level of the operation and maintenance work of the power transmission line.

Description

technical field [0001] The invention relates to the field of high-voltage transmission line operation inspection, in particular to an intelligent statistical method for important intersections and spans of transmission lines based on a supergraph platform. Background technique [0002] The important crossing section of the transmission line is a special section of the line, and it is also a section that needs to be paid attention to in operation and maintenance. Many of the special rectification work released by the power grid every year involve the rectification of important crossing sections. At present, there are mainly two types of statistics and maintenance methods for important crossing sections of transmission lines. One is reported by transmission line operation and maintenance personnel and compiled into a list by management personnel. The second is that the operation and maintenance personnel combined with the daily inspection work of transmission lines to check a...
