Example Embodiment

[0062] Example 1

[0063] The automatic measurement system for the inclination of transmission line towers described in this embodiment includes a drone, an RTK positioning module and a lidar module mounted on the drone, an RTK positioning base station, a lidar base station, and an intelligent control terminal; The RTK positioning base station and the lidar base station are set on the ground and around the transmission line tower. The RTK positioning module adopts RTK carrier phase differential technology positioning technology, which can realize centimeter-level positioning services, and the collected UAV base station and radar base station information reaches centimeter-level accuracy, which ensures the smooth implementation of automatic driving technology. Moreover, the positioning technology is not subject to strong electromagnetic interference, and combined with high-precision laser modeling, it can collect laser point cloud data for multi-loop and multi-base poles.

Abstract

The invention discloses an automatic measuring system for the inclination of a transmission line tower and a measuring method thereof. The measuring method comprises the following steps: acquiring thecoordinates of the transmission line tower, the height of the tower and the size of a crossbar, and transmitting data to an intelligent control terminal by an unmanned aerial vehicle to form a KML file of a tower path; planning an unmanned aerial vehicle autopilot modeling route in conjunction with the scanning area of a laser radar, the coordinates of transmission line tower, the height of the tower and the maximum length of the crossbar; flying according to the autopilot modeling route to build a laser point cloud model of the transmission line tower; and performing coordinate transformation and data fitting on POS data and IMU data to generate point cloud las data, extracting the spatial coordinates of ten points, including a tower center point, base datum positioning points and connecting points of a tower material, and calculating the tower inclination by using a ten-point measurement method for tower inclination. The automatic measuring system and method can automatically measure the inclination of the tower, have the advantages of high accuracy, easiness in operation and high efficiency, and are applicable to the field of inclination measurement of the transmission line tower.

Description

technical field [0001] The invention relates to the field of high-voltage transmission line operation inspection, and more specifically, to an automatic measurement system and a measurement method for the inclination of transmission line towers. Background technique [0002] The high-voltage transmission line is the main artery to ensure the stable operation of the power grid and the cornerstone to ensure the power supply of the society. With the development of my country's economy, the demand for power supply is increasing year by year, the mileage and scale of transmission lines are increasing year by year, and becoming more complex, the number of transmission lines under the jurisdiction of line inspection units is increasing year by year, and the requirements for power supply reliability are increasing year by year ;The line spans a wide range, and the operating environment is complex and harsh. A large number of transmission lines are located in mountains, riverbeds, and...
