[0001] The present invention relates to the field of logistics and transportation facilities, and in particular, to the improvement of drone logistics airports. Background Art

[0002] With the widespread application of drone technology in the logistics industry, the existing drone logistics supporting facilities have many limitations. On the one hand, the traditional drone apron has a single function and can only provide a simple take-off and landing site. It lacks effective integration with other logistics links, which makes it difficult for drone delivery and ground logistics delivery to work together, and the logistics efficiency is low. On the other hand, there is a lack of systematic solutions in terms of drone battery management, cargo loading and unloading, and equipment maintenance. For example, the battery charging facilities are simple, the charging efficiency is low, and there is a lack of a spare battery replacement mechanism, which affects the drone's endurance and operation frequency.

[0038] Working principle: When the UAV performs logistics distribution tasks, it first accurately lands on the designated helipad according to the guidance signs on the top floor of the helipad unit 1. At this time, the logistics management system controls the logistics transmission unit 2 to transfer the goods to be loaded and unloaded to the vicinity of the corresponding helipad according to the cargo distribution information. At the same time, the robot 5 in the storage bin 3 adjusts the positioning platform 7 to a suitable height through the lifting mechanism 6 under the command of the control box 52, and moves it to a position close to the helipad. When the UAV needs to replace the battery, the robot 5's mechanical arm 51, under the control of the control box 52, opens the door 8, enters the battery charging box 4 in the storage bin 3 to take out the fully charged battery pack, and then moves to the bottom of the UAV to remove the old battery and replace it with a new battery. During the cargo loading and unloading process, the mechanical arm 51 selects a suitable end effector according to the type and shape of the cargo, grabs the cargo from the helipad or the conveying mechanism 21, and places it on the positioning platform 7, or moves the cargo on the positioning platform 7 to the UAV or the conveying mechanism 21. The positioning sensor on the positioning platform 7 monitors the position information of the cargo and the mechanical arm 51 in real time, and feeds this information back to the control box 52 of the robot 5. The control box 52 adjusts the movement path and operation sequence of the mechanical arm 51 according to this information to ensure the accuracy and efficiency of cargo loading and unloading. During the whole process, each unit exchanges data and works collaboratively through wireless communication technology or preset electrical connections, realizing seamless connection between drone logistics distribution and other logistics links.
