Abstract

The present invention relates to the power grid patrol inspection system field, in particular to an unmanned aerial vehicle-based power grid patrol inspection method and system. The method comprises the following steps of separately detecting and calculating the magnetic induction intensity information within a factor point fixed distance according to the power grid factor points, according to the magnetic induction intensity information data obtained in the previous step, establishing the magnetic induction intensity information data of each independent patrol inspection area, and according to the geographic position relation or the connection relation of the independent patrol inspection areas, establishing an ordinary state magnetic induction intensity information data system of a whole power grid; according to the patrol inspection area of each unmanned aerial vehicle, storing the ordinary state magnetic induction intensity information data of the to-be-inspected areas in the unmanned aerial vehicles, according to the divided areas, releasing the corresponding unmanned aerial vehicles to collect the real-time magnetic induction intensity information; using a second processing system in the unmanned aerial vehicles to compare the data automatically and upload the abnormal signals, according to the feedback information, using an analysis processing center to determine and analyze, and according to the information real-timely fed by the unmanned aerial vehicles, controlling the work content of the unmanned aerial vehicles.

Description

technical field [0001] The invention relates to the field of power grid inspection systems, in particular to an unmanned aerial vehicle-based power grid inspection method and system. Background technique [0002] Regular power grid inspection is an important measure to ensure the normal operation of the power grid and eliminate accidents or potential safety hazards. The existing inspection methods are mostly manual inspections and inspections with testing equipment, which is affected by weather and other factors and has low efficiency. With the advancement of wireless transmission and computer technology, a reality inspection system has appeared on the market. Although the system has a fast feedback speed, it needs to improve and perfect all parts of the power grid system, and the investment is relatively large. [0003] In recent years, UAV technology has developed rapidly, and the use of UAVs for cruise detection has been widely used in various fields. China has a complex...

Problems solved by technology

There are several problems in applying this technology to the power grid inspection. On the one hand, the inspection of a large area of ​​the power grid means a huge amount of data information, and because the inspection operation near the power grid is inevitably disturbed by the power grid, the larger the amount of data, the larger the amount of data. Its fidelity and transmission efficiency will also be adversely affected, especially in mountainous or remote areas, where data transmission efficiency is low, and these data may not be fed back in time, which will affect the efficiency of system inspection; on the other hand, during the actual power grid operation , most of the structures and functions are in a normal state. The purpose of inspection is to find short-circuit, grounding and other faults caused by very few structural abnormalities. Therefore, continuous shooting operations and a large number of analog video signals will cause a lot of redundant work and data. waste of resources
