Unmanned plane patrol method and system

Abstract

The invention provides an unmanned plane patrol method and system. The method comprises steps that a data acquisition step, the data is acquired; a facial area generation step, a facial area object is generated; a task sub area planing step, the DEM data is processed through GIS buffer area analysis to generate the facial area object, and the facial area object is divided into multiple sub areas according to a height difference threshold of an unmanned plane; a course data generation step, the preliminary course data is sequentially connected to generate the course data; a patrol data acquisition step, the unmanned plane flies along a line determined by the course data and acquires the patrol data, and the patrol data comprises the original image data and the POS data; and an automatic line defect analysis step, a power line dangerous point interpretation result is automatically generated. Through the method, automatic patrol of the unmanned plane is realized through automatic task area patrol planning and automatic line defect analysis of the unmanned plane.

Description

technical field [0001] The invention relates to the field of detection of power transmission equipment, in particular to a line inspection method and system of an unmanned aerial vehicle. Background technique [0002] In recent years, with the increasing scale of overhead transmission lines, especially ultra-high voltage AC and DC lines, most of them are distributed far away from cities and main traffic roads, and the crossing of line corridors and the surrounding terrain environment are becoming more and more complex. At the same time, my country's national economy The continuous and rapid development of my country's power industry has put forward higher and higher requirements. In mountainous areas, there are large differences in regional climate, and there are many micro-topography and micro-meteorological areas. There are many problems such as complex corridor environment and crossover in plain areas. In order to ensure the safe operation of transmission lines, regular in...

Problems solved by technology

[0003] The manual inspection method requires close-up visual inspection, and is prone to misjudgment and misjudgment due to subjectivity; it is labor-intensive, dangerous, and expensive, and the input is not proportional to the output; it is time-consuming, inefficient, and easily restricted by the terrain. Timely detection of line problems or some lines that cannot be inspected. At the same time, with the development of intelligent line inspection technology, manual line inspection is gradually becoming a supplementary means of auxiliary inspection

[0004] Although the helicopter inspection line can be equipped with visible light, lidar, infrared and other shooting equipment, which greatly expands the content of line inspection, it also has certain defects, such as: 1. The degree of automation is low, and at least two people are required to operate on the plane, and one person to operate Inspection equipment, one person visually inspects line equipment, records defects, and is easy to miss inspection; second, it is dangerous and difficult to operate, and its maneuverability is not as convenient as that of fixed-wing drones; third, the cost of inspection is high, mainly reflected in the cost of expensive helicopters , making it difficult to give full play to and popularize the overall advantages of helicopter inspections

[0005] On the whole, the fixed-wing UAV line inspection method has strong maneuverability, high operating efficiency, and low engineering cost. However, at present, the fixed-wing UAV line inspection method is still in the stages of technical solution exploration, operation mode promotion, and intelligent inspection experiments. , From UAV line inspection task planning to line defect identification, a lot of manual participation is required, that is, the automatic line inspection of UAV has not yet been realized
