A drone airport can provide drones with storage space, environmental monitoring, data transmission, power supply and other functions, enabling remote control and unmanned operation of drones, effectively improving the efficiency and potential of drone applications.

[0003] However, due to the limited endurance of existing drones, automatic airports should be deployed near the inspection operation area as much as possible. The airport on the transmission and distribution line tower is deployed above the tower, which is convenient for inspection and makes full use of the existing tower resources. However, the power supply problem of the airport has become an important factor limiting the application scenarios of the airport on the tower.

[0004] Wind-solar complementary power generation refers to the technology of using wind power and solar energy, two renewable energy sources, to generate electricity in synergy. The principle is to integrate wind turbine generators and photovoltaic modules together to make them work together to maximize the use of natural resources. Since wind turbines and solar arrays are two types of power generation equipment that generate electricity together, the shortcomings of independent wind power and photovoltaic systems can be made up in terms of resources.

The system adopts an integrated photovoltaic power generation and wind power generation energy supply method to continuously provide energy supply for the airport, effectively solving the problem of difficulty in obtaining electricity in remote areas or some overhead distribution lines, reducing the difficulty of airport deployment, reducing the cost of material construction, and shortening the airport deployment cycle. In addition, wind power and photovoltaic power generation are clean energy and more environmentally friendly. At the same time, the system uses direct current for power supply, which helps to improve energy utilization, reduce the use of current conversion devices, and thus reduce airport energy consumption, so that the airport has low power consumption capabilities. In addition, the system can be deployed at a high place on the power tower to avoid strong signal interference due to too low deployment height and low safety of the take-off environment due to obstruction during take-off. Since the system uses wind power and photovoltaic power generation for power supply and energy storage, it can still maintain the inspection operation capability when the line is powered off.
