System and method for power line inspection

Abstract

The invention provides a system and a method for power line inspection. The system comprises a laser radar system mounted on an unmanned aerial vehicle. Real point cloud data is obtained and processedby the laser radar system mounted on unmanned aerial vehicle so as to provide a data foundation for power line monitoring personnel. The system further comprises a three-dimensional measurement and analysis module. The three-dimensional measurement and analysis module is used for realizing distance measurement and area measurement of any point on the line; measuring coordinate and elevation of each point of the power line, spatial distance between any two points and elevation of any point directly and accurately; and measuring interphase distance of power lines accurately, so as to provide aprecise scale for the manufacturing and mounting of spacer. According to the system and the method for power line inspection, the invention has the advantages that the high-precision laser point cloudand the high-resolution digital image can be rapidly acquired, the operation mode and technical advantages that are not possessed by the traditional mapping approaches are brought to whether the design selecting of the trend of the to-be-built line or the dangerous point inspection of the existing line, line asset management and various professional analysis.

Description

technical field [0001] The invention relates to the field of electric power line inspection, in particular to a system and method for electric power line inspection. Background technique [0002] In recent years, with the rapid development of China's economic construction, the demand for electricity has grown rapidly, and the demand for power grid construction has become increasingly strong. At the same time, in the face of the established long power network, how to effectively manage it to ensure the normal operation of the power grid and ensure the safe transmission of power is even more important. The occurrence of a blackout accident not only brings losses to the economic benefits of the power grid operating enterprises, but also has a serious impact on the power users and the whole society; [0003] Due to the continuous expansion of the domestic power grid, long-distance transmission lines such as UHV lines are growing rapidly, and many transmission lines are distribu...

Problems solved by technology

At present, power line inspection work is mainly carried out by electric workers going over mountains and mountains, using manual observation or drone image viewing to inspect existing power lines, which has high work intensity, long work cycle, unintuitive data, low precision, and low degree of reuse. Disadvantages such as high height and difficulty in working in areas with complex terrain
