The development of China's aviation logistics industry is ushering in an important opportunity period.In recent years, with the improvement of residents' consumption ability and the change of consumption mode, the sustained and rapid growth of express, special goods and cross-border e-commerce has brought a lot of air transportation demand and put forward higher requirements for the air logistics industry. Meanwhile, the "one belt, one road" and the pilot area of trade and other national strategies and the intensive publication of promoting the logistics industry to reduce the cost and increase efficiency have also put forward new and higher requirements for the development of aviation logistics industry.
Automated UAV express system uses UAV instead of manual delivery of express, aiming to realize the automation, unmanned and informatization of express delivery, improve the delivery efficiency and service quality of express, so as to alleviate the contradiction between express demand and express service ability.The implementation of this system can effectively deal with the huge increase of orders, eliminate the risk of "warehouse explosion" of express, improve the service quality of express industry, reduce the delay rate, damage rate, loss rate and express complaint rate of express, reduce the operation cost, warehouse cost and labor cost, improve the competitiveness of the industry, and make the delivery of express more safe, reliable and quick.
At present, SMD logistics UAV has been used in point-to-point transportation between warehouses of logistics enterprises. In particular, it is widely used in scenes with inconvenient ground transportation such as crossing islands, mountains and deserts, and has played a great role in the logistics industry. On July 15, 2015, the Federal Aviation Administration approved the first commercial UAV delivery, marking a milestone in the development of such a system.In the future, the role of UAV will be enhanced and even replace the fleet in some cases, which will have an important impact on energy consumption, public safety, personal privacy, air pollution, urban noise and air traffic management, road congestion, urban planning and consumption patterns in urban areas. Realize the automation, visualization, controllability, intelligence and networking of logistics through UAV, so as to improve the utilization rate of resources and the level of productivity.
