Embodiment Construction

[0042] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, but not for limiting the protection scope of the present invention.

[0043] It should be noted that, in the theory of electric wire mechanics, a continuous section refers to a tension section composed of several straight-line poles and towers; an isolated section refers to a tension section composed of only tension-resistant poles and towers. After the point cloud data in the transmission line channel is obtained, the point cloud is divided into power lines, towers, houses, vegetation and other categories according to the characteristics of the ground objects. The point cloud data belonging to the power line is extracted, and combined with the corresponding design data, the point cloud data belonging to the power line is sequentially di...

Abstract

The invention discloses a point cloud data-based power transmission line continuous span safety coefficient back calculation method, which can realize accurate and rapid back calculation of a power transmission line safety coefficient by combining power transmission line design data, a wire mechanics theory and meteorological condition data during power line point cloud data acquisition, a foundation is laid for analysis and prediction simulation of the safety distance of the power transmission line, and meanwhile, the safety coefficient obtained through back calculation of a newly-built line can also serve as an important reference basis for line acceptance.

Description

technical field [0001] The invention relates to the technical field of transmission line safety operation and maintenance and construction acceptance, in particular to an inverse calculation method for transmission line continuous gear safety coefficient based on point cloud data. Background technique [0002] Transmission line safety factor is an important parameter in the process of line design and operation and maintenance. After the line is completed, there will be a certain deviation between the actual safety factor of the transmission line and the design value due to the construction personnel's loose or too tight line and the aging of the power line during the construction process. At present, it has become the main method of transmission line operation and maintenance to use UAV or helicopter to carry laser LiDAR equipment to obtain line point cloud data, and then analyze and simulate line safety distance. Accurately obtaining the safety factor of the transmission l...
