[0002] Base stations are key infrastructure in mobile communication networks, used to achieve wireless signal transmission between mobile terminals and communication networks. A base station is a radio transceiver that covers a certain area through radio and transmits information with mobile terminals through a mobile communication switching center within this area. It usually consists of devices such as antennas, transceivers, and base station controllers. During the construction of base stations, high-altitude operations are often required. With the rise and popularity of unmanned aerial vehicles, more and more survey and maintenance work can be remotely carried out through unmanned aerial vehicles, improving the convenience of base station construction and maintenance;

Positioning suction cups 6 are fixedly installed on the cross bars 17. An adapter arm 18 and a pump 13 are fixedly installed on the lower surface of the fixed base 7.

Through regular inspections, the drone can quickly detect potential faults of base station equipment, give early warnings and arrange repairs, improving the operation stability and reliability of the base station. At the same time, in case of emergencies, when the ground communication base station may be damaged or unable to work properly, the drone equipment can carry the base station equipment and quickly fly to the disaster area to serve as a temporary aerial base station, quickly build a regional wireless network, and provide emergency communication services.
