Intelligent inspection system and inspection method for electric transmission line by unmanned aerial vehicle

Abstract

The invention discloses an intelligent inspection system and an inspection method for an electric transmission line by an unmanned aerial vehicle. The intelligent inspection system comprises an inspection mission planning system, a dispatching system, a monitoring system, an inspection result processing platform and mobile branch stations, wherein the inspection mission planning system communicates with the inspection result processing platform and the dispatching system respectively; the inspection result processing platform and the dispatching system communicates with the monitoring system respectively; the monitoring system is connected and communicate with the mobile branch stations. The inspection method has the benefits that factors of the inspection unmanned aerial vehicle, inspection equipment, an inspector, and the like accessing the dispatching platform through a dispatching terminal can be dispatched effectively to realize equipped configuration of unmanned aerial vehicle inspection resource; the usage rates of personnel and equipment can be improved; the no-load rate and vacancy rate of the inspection equipment are reduced; through centralized monitoring of condition information inspected by the unmanned aerial vehicle, unmanned aerial vehicle inspection dispatching personnel can master unmanned aerial vehicle inspection in the large effectively; the service life of the unmanned aerial vehicle is prolonged.

Description

technical field [0001] The invention belongs to the field of operation and maintenance of electric power systems, and relates to the field of unmanned aerial vehicle transmission line inspection, in particular to an intelligent inspection system and inspection method for unmanned aerial vehicle transmission lines. Background technique [0002] UAV line inspection is playing an increasingly important role in transmission line inspection, which can greatly reduce the workload of power service personnel, reduce the probability of possible personnel danger, reduce the maintenance cost of power equipment, and improve the safety of the power grid sex and reliability. [0003] At present, there are many problems in the intelligent inspection of transmission lines with drones: [0004] 1. Different inspection tasks correspond to different inspection transmission lines and inspection purposes. The inspection equipment and inspection models are also different.

AI Technical Summary

Problems solved by technology

[0004] 1. Different inspection tasks correspond to different inspection transmission lines and inspection purposes. The inspection equipment and inspection models are also different. The inspection involves complicated and scattered equipment, which is easy to forget and lose. During the inspection process, the lack of accessories and other situations frequently occurred, which seriously affected the efficiency of inspections.

[0005] 2. In the case of limited inspection resources, especially when there are many inspection tasks and strong constraints between inspection tasks, it is necessary to reasonably schedule inspection resources and equipment

Most of the existing task scheduling methods are aimed at personnel scheduling and regional scheduling. The scheduling geographical area is small, the scheduling equipment is relatively single, and the problem of no-load inspection is prominent.

There is still a lack of a dedicated dispatching system for UAV line inspections. The dispatching methods of other industries are directly applied to the dispatching system for UAV line inspections. The effect is not ideal, and there are still many problems to be solved.

[0006] 3. It is dangerous to use UAVs for transmission line inspections, especially in areas with harsh natural environments and variable climates such as mountains and plateaus. At present, the domestic monitoring of UAV inspections There are few systems, and most of the proposed methods are in the experimental stage, and they are all for monitoring a single UAV, but there is no centralized monitoring for multiple inspection UAVs, which cannot be achieved through modern technical means and Management method Centralized monitoring of drone inspections

[0007] 4. Most of the existing UAV monitoring objects are the image data of the UAV inspection, and there is less monitoring of the status information, pod information and meteorological information of the UAV inspection. For the inspection result data processing Low degree of informatization and automation

[0008] 5. At present, there is no effective association between the UAV inspection image and the inspection transmission line information. Therefore, the inspection image cannot be retrieved based on the transmission line information, and the inspection image cannot be effectively managed. The management and processing of inspection results are chaotic, which affects the judgment of inspection defects and the efficiency of defect elimination

[0009] 6. Effective defect diagnosis and defect identification processing cannot be performed on the UAV inspection result data

The existing inspection defect identification method codes the defect position into the image file by adding layers, the data processing complexity is high, the data processing and storage volume is large, and the speed and efficiency of defect identification are low

For the defective image after marking, if the copy of the image is not saved, the original image of the inspection is easily lost, resulting in irreparable loss
