Description

Technical Field

[0001] The present invention relates to a rapid stowage system and method for random cargo in multiple loading units of a feeder cargo plane, and in particular to a technical method and a corresponding stowage system for rapidly, efficiently and accurately stowing random bulk cargo into a loading unit with clear stowage requirements, belonging to the technical field of system control methods. Background Art

[0002] With the rapid development of e-commerce and logistics industries around the world, while the scale and volume are gradually expanding, logistics services have evolved from the single demand of "goods delivery" to today's diversified demand of "classified delivery, timely delivery, and quality delivery", which puts forward the requirements of multi-level air transportation for air logistics. In 2018, JD.com released the world's first annual report focusing on the development of drone industry in the logistics field, "Annual Report on the Development of World Logistics Drone Industry". The report systematically sorted out the core elements of the development of logistics drone industries in various countries around the world, such as the technical level, policy environment, and market demand. In particular, it focused on analyzing the latest development strategies of major logistics drone companies in the world, such as Amazon, UPS, and Google. At the same time, combined with the development needs of my country's logistics industry, it proposed for the first time the future "trunk-branch-terminal" three-level intelligent aviation logistics system.

[0003] Since the concept of the multi-level air transport logistics system has just been proposed, there is no standardized definition of the "trunk", "feeder" and "terminal" air logistics systems at all levels. According to the existing civil aviation system standards, trunk-level cargo aircraft are wide-body and narrow-body cargo aircraft in the current civil aviation transportation system, with a range of generally hundreds of kilometers to thousands of kilometers, and a single cargo capacity of tens to hundreds of tons. The terminal-level cargo aircraft is the current multi-rotor drone for cargo, with a range of generally within 30 kilometers and a single cargo capacity of less than 30 kilograms. The feeder-level cargo aircraft has a transportation distance and cargo capacity between the "trunk" and "terminal" air logistics systems. Different models can be developed according to specific freight needs. It is suitable for air logistics transportation from logistics hub nodes to logistics center nodes within provincial areas. Its range is generally 100-500 kilometers, and the single cargo capacity is around 1-5 tons.

[0004] At present, feeder-class cargo aircraft are a blank area in the three-level air logistics system, and are still in the initial stage worldwide. With the strong demand of China's air logistics market and the gradual refinement of the industry, my country's research and development in this field is relatively fast. In October 2017, the feeder-class cargo UAV AT200, developed by the Institute of Engineering Thermophysics of the Chinese Academy of Sciences and Longstar UAV Company as the overall unit, jointly with the 618th Institute of Aviation Industry, the 54th Institute of China Electronics, the 773rd Institute of Aerospace, and the Northwest University of Technology, completed its first flight. The aircraft has a payload of 1.5 tons, a total length of 11.84 meters, a wingspan of 12.80 meters, a height of 4.04 meters, and a cargo hold volume of 10 cubic meters. This drone can efficiently complete point-to-point freight feeder transportation services and is the world's first tonnage-class feeder-class cargo UAV.

[0005] At present, the feeder-class cargo UAVs under development have mainly conducted flight performance tests of empty aircraft, and have not yet conducted flight tests under cargo loading conditions. This series of UAVs still needs to undergo a series of flight tests with different cargo loading amounts, multiple complex flight environments, and different take-off and landing conditions before they can meet the test flight certification standards and truly serve my country's aviation logistics industry. As for the existing feeder-class manned aircraft, they are mainly used in the fields of manned, surveying, aerial photography, agriculture and forestry plant protection, and rarely involve the cargo loading process. Even if there is a cargo loading process, manual loading is still used due to its small cargo load. Therefore, whether it is the feeder-class cargo UAVs under development or the more mature feeder-class manned aircraft, there is currently no more mature cargo efficient loading solution applied to the logistics industry.

[0006] With the diversified development of air logistics demand and the gradual improvement of the three-level intelligent air logistics system of "trunk-feeder-terminal", the relatively blank "feeder" air logistics transportation will gradually become a hot spot for technology and market research. The efficiency of cargo loading will inevitably become one of the core technical indicators affecting the development of feeder freighters. The improvement of this indicator can not only improve the operating efficiency of the air logistics system of feeder freighters within the airport working range, but also improve the airport's cargo professional capabilities. At present, the technology of industrial-grade feeder cargo aircraft used in the logistics industry in the civil field is still in the initial stage of research and development, and its supporting cargo efficient loading technology is in its infancy, and it is in urgent need of rapid research and development of innovative technologies.

[0007] For existing trunk-class cargo aircraft, their cabin structures are all wide-body and narrow-body structures, and aviation containers (Unit Load Device, ULD for short) are used during the cargo loading process to complete the efficient loading of cargo. Because their cabin structures are relatively large, the range of changes in the center of gravity of the aircraft during cargo loading is relatively small, and their container units only consider technical issues of cargo loading, which are less related to the cabin structure. However, the cabin structure of feeder-class cargo aircraft is much smaller, and it belongs to an ultra-narrow-body cabin structure. The law of changes in the center of gravity during its loading process is significantly different from that of trunk-class cargo aircraft. In order to meet the overall weight requirements of the aircraft, the weight of each container unit must be distributed according to the overall weight. The weight mass is different, and the weight and volume of the cargo itself are also different. This is a problem of standardized loading of "random" cargo, so a set of efficient, fast and accurate loading systems are needed to achieve standardized loading of random cargo.

In the present invention, the number of the code scanning part and the push part is the same, and they are arranged close to each other. In terms of position, the several push parts are all arranged at the inner side of the endless conveyor belt 1. The driving motors 8-1, 8-2, 8-3, and 8-4 are connected in parallel with each other and electrically connected to the centralized control part.
