Tour inspection device with 3D scanning function and detection method thereof

Abstract

The invention provides a tour inspection device with a 3D scanning function and a detection method of the tour inspection device. The tour inspection device comprises a laser transmitter, glass filters and CCD cameras and is characterized in that the CCD cameras arranged in an included angle mode are respectively provided with one glass filter, the laser transmitter and the CCD cameras are respectively connected with a PC storage processor, the device is carried on an unmanned aerial vehicle and detects overhead lines and pole towers from different angles. Compared with the prior art, the tour inspection device with the 3D scanning function can obtain three-dimensional images and size data of a detected device from different angles, is beneficial to judging the running state of an electrical device, can detect faults clearly, accurately and rapidly in all directions, and ensures normal running of electric transmission lines.

Description

technical field [0001] The invention relates to a patrol device, in particular to a patrol device with a 3D scanning function and a detection method thereof. Background technique [0002] In recent years, with the continuous acceleration of China's electric power development, China's power grid has also developed rapidly. The operating voltage level of the power grid system has continued to increase, and the network scale has also continued to expand. Power grid and China Southern Power Grid have 6 large-scale regional power grids across provinces, and have basically formed a complete long-distance transmission grid. [0003] The "Eleventh Five-Year Plan" period is an important 5 years for the construction of my country's power grid, and a large number of major transmission projects have started construction. Among them, a number of high-grade, long-distance, and large-capacity power transmission projects such as Hainan Interconnection, Huliao DC, Xinjiang and Northwest Int...

Problems solved by technology

[0008] In the past, the inspection equipment carried by the UAV device used for overhead line and tower inspection is generally a video camera, a visible light digital camera, etc., and the images obtained can generally only find broken strands of the line, damage or cracks in the umbrella group of insulators, tower body The presence or absence of abnormal fittings and other phenomena cannot be used to judge the specific circumstances of the abnormality, such as the number of broken strands, the degree of damage to the insulator umbrella group, etc. It is necessary for the staff to propose solutions based on experience, which is greatly affected by human factors. The scientific nature is not high; sometimes, due to the problem of shooting angle, the phenomenon that hidden dangers of electric equipment safety cannot be found also happens from time to time
