[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] In this application, the terms "comprising," "including," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0040] Spreadsheet software itself does not have the business function of "cabin merging". When the loadmaster needs to treat adjacent cabins as a whole for trimming, he cannot directly perform the "merging" operation in the spreadsheet. He has to manually calculate the total weight of the two cabins outside the spreadsheet and then distribute it equally. However, this method has low trimming efficiency and is prone to affecting trimming accuracy due to human error.

[0041] In addition, after the trim is completed, the trim results need to be printed from the spreadsheet into a paper manifest, which is then delivered to the flight crew by a designated person. This process is time-consuming (there is a significant delay from the completion of trim to the flight crew receiving the manifest), increases additional manpower and logistics costs, and poses a risk of document loss or delay, which does not meet the requirements of modern operational efficiency.

[0042] To address this, embodiments of the present invention propose a data trimming method, apparatus, electronic device, and storage medium. After cargo hold merging in a visual interface, the trimming plan can be automatically determined by the trimming personnel, eliminating the need for manual calculations and improving trimming efficiency and accuracy. Furthermore, after obtaining the trimming plan, an electronic manifest message containing at least the trimming plan is pushed to the crew's electronic flight bag equipment, significantly shortening information transmission time.

[0043] It should be noted that the data balancing method, device, electronic equipment and storage medium proposed in this solution can be applied to various types of cargo aircraft (such as the 777 cargo aircraft).

[0044] See Figure 1 The flowchart illustrates a data balancing method provided by an embodiment of the present invention, which includes:

[0045] Step S101: Display the visualization interface rendered from the aircraft cargo hold layout.

[0046] In the specific implementation step S101, Canvas is used to render the aircraft cargo hold layout into an interactive visual interface and display the visual interface.

[0047] In some specific embodiments, the visualization interface includes a merging area and multiple graphic blocks, each graphic block corresponding to a cargo hold. The graphic block displays at least the cargo hold's load capacity and hold number (hold ID). The merging area is used to merge the cargo holds corresponding to the graphic blocks towed to the merging area.

[0048] In other words, in the visualization interface, each cargo hold is represented by an independent, draggable graphic block, which dynamically displays information such as the hold number and the load weight of the hold.

[0049] For example Figure 2 As shown in the example diagram of the visualization interface, the visualization interface includes a merged area and multiple graphic blocks. Each graphic block corresponds to a cargo hold, and the graphic block displays at least the cargo hold's stowage weight and hold number.

[0050] Step S102: In response to the merge operation triggered on the visualization interface, merge multiple cargo holds.

[0051] In the specific implementation step S102, in response to the drag operation of any graphic block in the visualization interface, the cargo hold corresponding to the dragged graphic block is merged, wherein the drag operation is used to drag the graphic block to the merged area.

[0052] In practical applications, the interaction of the visual interface can be implemented using Vue.js. The visual interface provides a graphical checkbox selection tool, which allows users to select multiple cargo holds corresponding to the graphic blocks that need to be merged at the same time by "checking" them, and then drag the selected graphic blocks to the merge area to merge the cargo holds.

[0053] For example Figure 3 Another example of the visualization interface shown illustrates that users can select two adjacent graphic blocks using a "√" and then drag the selected graphic blocks to the merge area to merge the cargo holds.

[0054] In some specific embodiments, after merging the cargo holds corresponding to the towed graphic blocks, a designated identifier is displayed on the graphic block corresponding to the merged cargo hold. This designated identifier is used to indicate that the merging is complete.

[0055] In other words, after merging the cargo holds corresponding to the dragged graphic blocks, a designated identifier is added to the graphic blocks corresponding to the merged cargo holds in the visualization interface. This designated identifier indicates which cargo holds have been merged.

[0056] For example Figure 4 As shown in another example of the visualization interface, a "merged" label is added to the graphic block corresponding to the merged cargo holds in the visualization interface, which helps users to intuitively know which cargo holds have been merged.

[0057] In some specific embodiments, this solution also provides a splitting function, which, in response to a splitting operation triggered on the visual interface, splits any merged cargo hold and then reselects other cargo holds that need to be merged.

[0058] It should be noted that when merging multiple cargo holds, a request carrying the "hold number of the merged cargo hold" and "container information" is sent to the backend via API for further processing to balance the cargo hold.

[0059] The container information includes at least the cargo space loading weight and model.

[0060] Step S103: Determine the trim scheme using the global index and the combined cargo hold load weights.

[0061] It should be noted that the global index includes at least a set of indices such as the crew index, fuel index, and aircraft empty weight index.

[0062] In the specific implementation of step S103, the takeoff weight, takeoff center of gravity, and center of gravity without fuel are calculated using the global index and the combined cargo hold load weight.

[0063] Specifically, the information such as the lateral lever arm coefficient of the "merged cargo space" is found in the business logic layer and plugged into the cargo space index calculation formula to calculate the cargo space index. Then, the cargo space index, the global index and the cargo space loading weight of the merged cargo space are combined to calculate the unfueled weight, unfueled index, unfueled center of gravity, takeoff weight, takeoff index and takeoff center of gravity.

[0064] Wherein, cabin index = ULD weight (lateral lever arm - constant A) / constant B; fuel-free index = sum of cabin indexes + crew index; takeoff index = fuel-free index + fuel index; dry weight = empty weight of aircraft + crew weight; fuel-free weight = sum of cabin load weights + dry weight; takeoff weight = fuel-free weight + takeoff fuel weight.

[0065] MOMENT (Oil-free) = (Oil-free index - C constant) B constant / (oil-free weight) + A constant; MOMENT (takeoff) = ((takeoff index - C constant)) B constant / takeoff weight) + A constant; BA = D constant; LENGTH = E constant; Center of gravity without fuel = (MOMENT (without fuel) - BA) / LENGTH; Center of gravity without takeoff = (MOMENT (takeoff) - BA) / LENGTH.

[0066] Determine the limit ranges (consisting of upper and lower limits) corresponding to takeoff weight, takeoff center of gravity, and unfueled center of gravity, respectively, and verify whether the takeoff weight, takeoff center of gravity, and unfueled center of gravity are within the limit ranges to determine the trim scheme, which includes at least the trim angle.

[0067] The content regarding the flat angle is as follows:

[0068] Lower takeoff weight limit <= takeoff weight <= upper takeoff weight limit;

[0069] Lower limit of takeoff center of gravity <= lower limit of takeoff center of gravity <= upper limit of takeoff center of gravity;

[0070] x11 = Lower limit of takeoff center of gravity;

[0071] y11 = (lower limit of takeoff center of gravity, lower limit of takeoff weight). It should be noted that "(lower limit of takeoff center of gravity, lower limit of takeoff weight)" means that the corresponding y value is found from the mapping table based on the lower limit of takeoff center of gravity and the lower limit of takeoff weight. The same applies to similar content thereafter.

[0072] x21 = Limitation on takeoff center of gravity;

[0073] y21 = (Upper limit of takeoff center of gravity, lower limit of takeoff weight);

[0074] x12 = Lower limit of takeoff center of gravity. It should be noted that the values ​​of x11 and x12 are the same.

[0075] y12 = (Lower limit of takeoff center of gravity, upper limit of takeoff weight);

[0076] x22 = Limitation on takeoff center of gravity. It should be noted that the values ​​of x21 and x22 are the same.

[0077] y22 = (Upper limit of takeoff center of gravity, upper limit of takeoff weight);

[0078] k11=(y11-y21) / (x11-x21);

[0079] b11=(x11 y21-y11 x21) / (x11-x21);

[0080] stab1 = Takeoff center of gravity k11+b11;

[0081] k12=(y12-y22) / (x12-x22);

[0082] b12=(x12 y22-y12 x22) / (x12-x22);

[0083] stab2 = Takeoff center of gravity k12+b12;

[0084] stab = (takeoff weight - lower limit of takeoff weight) (stab2-stab1) / (takeoff weight upper limit-takeoff weight lower limit)+stab1.

[0085] The above is an example of the trim angle. The obtained trim angle can ensure that the aircraft's center of gravity is within the safety envelope, thereby ensuring the balance and safety of the aircraft during takeoff.

[0086] In some specific embodiments, an electronic manifest message containing at least the trim scheme is pushed to the crew electronic flight bag (EFB) device.

[0087] In practical applications, an API interface is provided for synchronizing electronic manifest messages and transmitting receipt status. The EFB device, as a downstream system, actively polls and calls this API interface according to a preset period (e.g., every few minutes). Through this API interface, the latest "electronic manifest message containing the trim scheme" is updated to the crew's EFB device in a timely manner, realizing automatic data synchronization and transmission.

[0088] It should be noted that a unified data exchange standard (such as JSON format) is used to transmit electronic manifest messages during data transmission.

[0089] In this embodiment of the invention, after the load control personnel merge cargo holds in the visual interface, the trim scheme can be automatically determined without manual calculation, thus improving the efficiency and accuracy of trim adjustments. Furthermore, after obtaining the trim scheme, an electronic manifest message containing at least the trim scheme is pushed to the crew's electronic flight baggage equipment, significantly shortening information transmission time.

[0090] In practical applications, one application scenario for this solution is as follows: Load coordinators can easily select adjacent cargo holds for merging through a simple checkbox operation on a visual interface. They then calculate data such as takeoff weight, takeoff center of gravity, and zero-fuel center of gravity in real time to obtain a trim plan and immediately generate an electronic manifest message containing the trim plan. With a single click, the electronic manifest message can be directly and securely pushed to the crew's handheld EFB device, significantly shortening trim and information transmission time and reducing labor and operating costs.
