TECHNICAL FIELD

[0002] Unmanned aerial vehicle logistics delivery refers to a logistics mode of cargo transportation by using unmanned aerial vehicle technology, which quickly and accurately delivers goods from a supply location to a receiving location by using unmanned aerial vehicles. This mode is a typical representative of the automatic and intelligent development of the logistics industry, and can break through the limitations of traditional ground transportation and realize flexible distribution in three-dimensional space. The core principle involves that the unmanned aerial vehicle carries goods, flies according to a preset route, and relies on GPS navigation, data link systems and flight control technology to complete autonomous flight. The unmanned aerial vehicle transmits position and state information in real time to the dispatch center through 4G network or infinite band communication, automatically plans a path after receiving an instruction, and sends a landing request to a self-service express cabinet or a designated location after entering a target area to complete loading and unloading tasks. In the actual application of unmanned aerial vehicle logistics delivery, when the unmanned aerial vehicle carrying goods arrives at the unloading point, the unmanned aerial vehicle must land to complete unloading with the assistance of manpower. The landing of the unmanned aerial vehicle needs to be calibrated and adjusted in position by lifting and translating, and for the unmanned aerial vehicle that needs continuous and reciprocal transportation, the reciprocating landing at the designated location for manual unloading will greatly prolong the overall unloading time, reduce the endurance time of the unmanned aerial vehicle, and affect the overall logistics transportation efficiency.
