Description

Planning methods for rapid automated loading of cargo aircraft Technical Field

[0001] This invention belongs to the technical field of aircraft cargo loading, and particularly relates to a planning method for rapid and automatic loading of cargo aircraft. Background Technology

[0002] Loading cargo onto an aircraft directly alters its center of gravity. The center of gravity affects both flight safety and fuel consumption. Therefore, cargo loading has a significant impact on flight safety and the economics of air transport. Currently, cargo placement on aircraft largely relies on human experience. When a shipment requires multiple aircraft, manually developing loading plans cannot simultaneously accommodate all aircraft. Furthermore, different people will provide different loading plans, resulting in varying loading effectiveness. Even the same person cannot consistently provide optimal loading plans. Human experience is difficult to pass on, and manually developing loading plans is slow and cannot consider the loading needs of multiple aircraft, leading to reduced transport efficiency.

[0003] In view of this, the present invention is hereby proposed. Summary of the Invention

[0004] The present invention provides a planning method for rapid automatic loading of cargo aircraft, which improves transportation efficiency by quickly distributing a batch of cargo to multiple aircraft and ensuring that the center of gravity of each cargo-loading aircraft is as close as possible to the ideal center of gravity. The technical solution of this invention has many beneficial effects, as described below: A planning method for rapid automatic loading of cargo aircraft, adaptable to loading cargo onto multiple aircraft, wherein each piece of cargo is pre-marked with a unique label. The planning method includes: S1: calculating the weight-to-volume ratio Ri of each piece of cargo; S2: sorting all cargo according to the weight-to-volume ratio from largest to smallest, forming a list LC; S3: removing cargo from the list LC in descending order of weight-to-volume ratio, and performing adaptation planning for each removed piece of cargo.

[0005] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects: the method has a simple algorithm, fast planning speed, and effectively solves the problem of cargo loading planning for multiple aircraft. When planning, the influence of cargo on the center of gravity of the aircraft is considered, so that the actual center of gravity of each aircraft is as close as possible to the ideal center of gravity. The center of gravity problem of each aircraft is considered from a global perspective, and the aircraft saves fuel to the maximum extent during flight transportation. Attached Figure Description

[0012] The cargo aircraft rapid automatic loading planning method shown in Figures 1 to 4 is suitable for loading cargo from multiple aircraft. Each piece of cargo is pre-marked with a unique label. The planning method includes: S1: Calculating the weight-to-volume ratio R of each piece of cargo. i = In the formula, V represents the volume of the goods, W represents the weight of the goods, and the subscript i represents the i-th item of goods; S2: Sort all goods in descending order of weight-to-volume ratio to form a list LC; S3: Take out goods from list LC in descending order of weight-to-volume ratio, and perform adaptation planning for each taken-out item. Specifically, adaptation planning for each taken-out item includes: determining whether the current goods can be assigned to an aircraft capable of loading the current goods (real-time acquisition of the current loading status of all aircraft); if so, summarizing all aircraft capable of loading the current goods to form a list LP; calculating the difference between the actual center of gravity and the ideal center of gravity of all aircraft in list LP after loading the current goods, where the ideal center of gravity is determined according to the aircraft model; obtaining all the differences, determining the aircraft corresponding to the smallest difference according to the comparison method, assigning the goods to the aircraft corresponding to the smallest difference, and recording the correspondence between the current goods and the aircraft (at this time, it is only a simulation and not a real loading, recording the goods and the aircraft). (One-to-one correspondence between aircraft) and the loading position of the cargo on the aircraft with the smallest difference. The loading positions are allocated according to preset rules to complete the allocation of all cargo. If not, an error message is sent, indicating that transportation is not possible. The preset rules for allocation include: for single-row cargo aircraft, the storage positions are numbered with the ideal center of gravity as the axis of symmetry, and the cargo is placed sequentially from the center to both sides on opposite sides. For example, when loading, position 1 is loaded first, then position 2, then position 3, and so on in a cyclical manner. For double-row cargo aircraft, the storage positions are numbered with the ideal center of gravity as the axis of symmetry, and the cargo is loaded sequentially from the center to both sides on opposite sides in an X shape. For example, positions 1 and 2 are diagonally opposite, and positions 3 and 4 are diagonally opposite, forming an X shape. When loading, the cargo is first placed in the diagonal storage position formed by positions 1 and 2, and then the cargo is placed in the storage position on the other diagonal, and so on in a cyclical manner.

[0013] The cargo is currently arranged in the cabin according to the numbers shown in the two figures below, in ascending order of the numbers. For single-row loading, refer to Figure 2; for double-row loading, refer to Figure 3.

[0014] Further calculations were performed to determine the difference between the aircraft's actual center of gravity and its ideal center of gravity. Represented as, In the formula, The weight represents the weight of the cargo loaded on the aircraft, and g represents the acceleration due to gravity. MI represents the distance of the cargo's center of gravity from the calculation origin, n represents the quantity of cargo, and MI represents the ideal center of gravity position. This method represents the operation of finding the absolute value. It enables the rapid allocation of a batch of goods to multiple aircraft, ensuring that the center of gravity of each aircraft carrying the goods is as close as possible to the ideal center of gravity. This reasonable allocation reduces fuel consumption during flight. It is a method for rapid and automatic cargo loading planning for multiple aircraft, simultaneously allocating goods to be loaded to multiple aircraft. This reduces complexity, increases efficiency, and speeds up the process, taking into full account the impact of the goods on the center of gravity of the aircraft without relying on human experience.

[0015] The overall process is as follows: 1. The yard staff enter the information of the goods to be loaded (goods name, size, weight, etc.) into the system.

[0016] 2. After all cargo information is entered, the automatic loading planning algorithm begins to formulate a loading plan.

[0017] 3. Once the loading plan is finalized, it will be distributed to the freight yard and the freight handlers responsible for loading the goods.

[0018] 4. The cargo yard sorts the cargo from each aircraft according to the loading plan and hands it over to the cargo handlers. The cargo handlers then load the cargo onto each aircraft according to the loading plan.

[0019] Referring to the system application shown in Figure 4, as follows: 1. The yard operators use handheld terminals (tablets, smartphones, etc.) with input, shooting and Internet functions to enter information such as cargo photos, weight, and dimensions, and send them to the data center via the network.

[0020] 2. After the data center's cargo area has entered all cargo information, it begins to plan the loading of cargo awaiting air transport.

[0021] 3. Once the loading plan is finalized, the data center will send the loading information to the freight yard and freight personnel via the network.

[0022] 4. Cargo yard staff sort the goods according to the loading plan, and place the goods loaded on different aircraft onto different transport vehicles and hand them over to the freight handlers.

[0023] 5. Cargo handlers can use handheld terminals to view the received loading plans and load the goods into the designated locations in the aircraft cargo hold according to the plans.

[0024] The product provided by this invention has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the embodiments above are merely for the purpose of helping to understand the core ideas of this invention. It should be noted that those skilled in the art can make various improvements and modifications to the invention without departing from the principles of the invention, and these improvements and modifications also fall within the protection scope of the invention claims.
