Background technique

Due to various complex geographical environments, my country's power lines have large coverage, wide distribution areas, long transmission distances, complex and changeable geographical conditions, and are significantly affected by environmental climate. Power lines are widely distributed and the surrounding environment is generally harsh. Long-term exposure to the sun, wind, sun, lightning, etc. will cause damage such as corrosion, abrasion, and self-explosion. If not detected and eliminated in time, it will bring great hidden dangers to the stable operation of power lines. Therefore, regular inspections of power lines, keeping abreast of changes in the line environment, and quickly discovering and eliminating hidden dangers can ensure safe and reliable power supply.

At present, the monitoring of power lines has always been through manual patrols, which is very time-consuming and labor-intensive, especially the laying environment of most high-voltage transmission lines is very harsh, which brings great inconvenience to monitoring personnel.

UAVs have the advantages of light weight, small size, easy to carry, low cost, automatic flight, good flexibility, and support for multiple inspection modes, etc., and can perform efficient, non-contact, and all-round inspections. If drones can be used instead of inspection personnel for cruising, the difficulty can be greatly reduced. UAV line inspection technology is currently the most advanced, a line maintenance method with the highest technological content, and has high practicability. UAVs are generally suitable for some remote mountain forest areas and some areas that are difficult for people to reach. Drones in these areas are more economical and at the same time can guarantee the safety of personnel.

In addition, non-contact fast charging can be arranged in a variety of places, and can provide charging services for various types of equipment, making it possible to charge anytime and anywhere.
