Problems solved by technology

The current inspection methods include: 1. Helicopter line inspection: The aerial inspector will inspect the line through the anti-shake telescope, etc., and use the visible light detector and infrared thermal imager equipped with the helicopter to accurately capture equipment defects and real-time operating status. However, this inspection method needs to formulate a flight plan in advance according to the path of the line corridor, surrounding environment, tower structure, electrical structure, etc., and the inspection cost is high, and long-term frequent use will pay high costs, and the safety is poor and the accuracy is low; 2. Robot line inspection: the robot is suspended on the overhead lightning protection line of the transmission line, and the lightning protection line corridor almost coincides with the wire corridor, so the line inspection robot can be controlled to walk along the lightning protection line by remote control to complete the transmission line inspection operation. In this mode, the robot can only follow the specified path for line inspection, and the observation field of view is too small

Embodiment 1

[0035] Such as figure 1 As shown, the UAV-based power line inspection system in this embodiment includes:

[0036] Unmanned aerial vehicle 1; Specifically, described unmanned aerial vehicle 1 comprises: RTK communication module and 4G / 5G communication module, at present unmanned aerial vehicle generally uses GPS to locate, and it is easy to cause large positioning error due to weather and environmental influence, makes it unable to The image information of the power device is accurately captured, resulting in inaccurate detection of the device; therefore, the UAV 1 in this embodiment can enhance the GPS search capability and obtain differential data through the RTK communication module including the RTK antenna and other components, Differential positioning can be performed, and the positioning accuracy can reach centimeter level, thereby improving the positioning accuracy. At the same time, the 4G / 5G communication module is used to achieve stable and efficient signal transmis...

Embodiment 2

[0050] This embodiment provides a power line inspection method implemented by the above-mentioned power line inspection system, which includes:

[0051] S1. Determine the transmission line according to the position information of several towers, and then determine the flight route of the drone according to the transmission line;

[0052] Specifically, first control the UAV to fly to a certain tower (such as image 3 001) above, record the latitude and longitude coordinates of the tower, then fly to the side of the tower, lower the aircraft to the same height as the tower, record the altitude of the tower, so as to determine the position of the tower, and repeat in turn to obtain several towers (Such as figure 2 002, 003...005) in the location information, and then connect some of the towers to determine the transmission line S (such as figure 2 Among them, the power is transmitted along the three towers 001, 002, 003 and the transmission lines connected to each other), and...

Description

technical field [0001] The invention relates to the field of power system operation and maintenance, in particular to an unmanned aerial vehicle-based power line inspection system and method. Background technique [0002] During the operation and maintenance of the power system, it is necessary to carry out refined inspections on the power line towers and their components on a regular basis. The current inspection methods include: 1. Helicopter line inspection: The aerial inspector will inspect the line through the anti-shake telescope, etc., and use the visible light detector and infrared thermal imager equipped with the helicopter to accurately capture equipment defects and real-time operating status. However, this inspection method needs to formulate a flight plan in advance according to the path of the line corridor, surrounding environment, tower structure, electrical structure, etc., and the inspection cost is high, and long-term frequent use will pay high costs, and t...
