Defect analysis device for transmission tower based on routing inspection of unmanned aerial vehicle and method

Abstract

The invention transmits a video data file not shorter than 30 minutes to a ground workstation by a video capturing device arranged on an unmanned aerial vehicle through ZigBee; the workstation can comparatively analyze the latest image and a historical image on the basis of the invention, can early warn, can timely label and then can forward the defect analysis information to the maintenance personnel through a message; the accuracy of the invention can be continuously promoted in the manner of directly covering the base drawing. The invention utilizes an aerial camera to perform highly and dimensionally comprehensive detection and fault analysis on a transmission tower and can realize full-automatic routing inspection; the information is inputted to the device in the manner of point-to-point communication of unmanned aerial vehicle-ground workstation; if the defect is found, the device can early warn in time and the unmanned aerial vehicle can be remotely controlled to label the defect, so that the maintenance personnel can conveniently and timely perform maintenance; and meanwhile, the whole analysis process has the advantages of accuracy and high speed; under an unattended operation condition, the complete operation can be performed.

Description

technical field [0001] The invention belongs to the field of electric power detection, and in particular relates to a device and method for analyzing defects of transmission poles and towers based on unmanned aerial vehicle inspection. Background technique [0002] The power system is different from other industries. Maintenance cannot interrupt production at will. It is necessary to make sufficient predictions before the accident occurs—to solve the fault before the accident occurs, and the focus is on the preventive inspection of the transmission line. Transmission lines are burdened with high voltage and high current for a long time. In recent years, with global warming, severe weather and weather have occurred frequently, which poses an increasing danger to the safe operation of the power grid. [0003] At present, domestic power grid detection mainly adopts manual line inspection, employing local residents as inspectors, and a small amount of experiments use modern meth...

Problems solved by technology

[0003] At present, domestic power grid detection mainly adopts manual line inspection, employing local residents as inspectors, and a small amount of experiments use modern methods such as helicopters to inspect lines. Inspectors regularly inspect high-voltage lines. This work is extremely difficult. Inspectors The labor intensity, the sense of responsibility of the line guards and the uneven line protection ability, the hardship of field work and the high height of some line towers all make it difficult to guarantee the detection effect of tower defects, and the inspection period is long (1 to 10 weeks) ), leading to the absence of line status supervision, which has left hidden dangers to the safety of transmission lines
