Description

[Technical Field]

[0001] [CROSS-REFERENCE TO RELATED APPLICATIONS] This application claims priority to a Chinese patent application filed with the China Patent Office on September 5, 2022, bearing application number 202211076577.1 and entitled "Method and apparatus for estimating flight passenger center of gravity," the entire contents of which are incorporated herein by reference.

[0002] The present application relates to the field of aviation information, and more particularly to a method and apparatus for estimating flight passenger center of gravity. [Background technology]

[0003] High safety is the basic premise and important guarantee for aircraft to take off on time, and is also the noble mission and responsibility of the civil aviation industry. Aircraft load capacity and balance are key elements in ensuring high safety. This involves effectively controlling the aircraft's center of gravity by rationally distributing passenger seats and cargo compartments, keeping the aircraft's center of gravity within a safe range, and thus ensuring the aircraft's flight safety.

[0004] Calculating the passenger center of gravity is a key step in the calculation of an aircraft's center of gravity. A loaded passenger center of gravity estimation device estimates the passenger center of gravity even when passenger data is not fully acquired, providing important support and effective assurance that the flight can take off on time. Because aircraft loading operations often begin a certain period of time before the flight takes off, various unknown situations may exist for the passengers during this process, such as having a seat assigned when purchasing a ticket but not having checked in, or not having a seat assigned when purchasing a ticket. Passengers not selecting a seat or not being checked in both mean that the seat ultimately selected by the passenger is uncertain. During this period, the aircraft simultaneously distributes and loads cargo from the cargo transportation system. The passenger center of gravity is an important basis for distributing cargo in the cargo hold. The calculation of the passenger center of gravity is primarily related to the passenger's weight and seat row. Performing center of gravity calculation after all passengers have checked in will inevitably delay cargo loading and cause flight delays.

[0005] Currently, during the loading process for a flight, it is not possible to predict the passenger center of gravity. Therefore, an initial calculation is made based solely on acquired passenger data, and then cargo is loaded based on this calculation and previous experience. Finally, after all passengers have checked in, if a center of gravity adjustment is required, it can only be corrected by adjusting the position of the cargo in the cargo hold. This method lacks prediction of the passenger center of gravity, so some cargo adjustment may be required. The more accurate the prediction of the passenger center of gravity, the better the means for loading cargo in the cargo hold. In this way, the probability of a center of gravity adjustment being required is greatly reduced by finally adjusting the cargo.

[0006] Therefore, how to accurately predict the flight passenger center of gravity is a problem to be solved in this field. Summary of the Invention [Problem to be solved by the invention]

Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without any creative efforts will fall within the scope of protection of the present application.

The term "in one embodiment" refers to "at least one embodiment," the term "in another embodiment" refers to "at least one other embodiment," and the term "in some embodiments" refers to "at least some embodiments."

[0024] It should be noted that the concepts of "first", "second", etc. mentioned in this application are only for distinguishing different devices, modules or units, and do not limit the order or interdependence of the functions performed by these devices, modules or units.

[0025] It should be noted that the modifications "one" and "multiple" referred to herein are intended to be exemplary and not limiting, and should be understood as "one or more" unless the context clearly indicates otherwise, as would be understood by one of ordinary skill in the art.

[0026] As shown in FIG. 1a and FIG. 1b, it is a schematic flow chart of a flight passenger gravity center estimation method provided by an embodiment of the present application, which includes the following steps:

[0027] In S101, passenger data for the flight to be measured is acquired from the departure system. Here, passenger data includes attributes of each passenger and seat attributes. Each passenger type includes passengers who have selected a seat and passengers who have not selected a seat. Passengers who have selected a seat include checked-in passengers, passengers who have not checked in but have selected a seat, passengers using a stretcher, passengers with additional seating items, jump seat passengers (referred to as passengers using a folding auxiliary seat), and baggage. Furthermore, seat attributes include the seat row number and seat number of passengers who have selected a seat.

[0028] In the present application, a stretcher passenger is a passenger who is unable to move and requires multiple seats. An additional seating item is a passenger's valuables that require a separate seat. A folding auxiliary seat passenger is a passenger who has purchased a pre-installed folding seat. Carry-on luggage is luggage carried by a passenger, and the luggage storage location is above the passenger's seat.

[0029] In addition, the types of passenger attributes include adult passengers, male passengers, female passengers, child passengers, and baby passengers. Generally, the seat row number indicates the seat row selected by the passenger, and the seat number indicates the seat selected by the passenger. A so-called seat row is a combination of seats pre-arranged on a flight, and multiple seat rows are pre-arranged on a flight, and each seat row includes multiple seats.

[0030] Checked-in passengers, non-checked-in passengers who have selected seats, passengers using stretchers, passengers with additional seating items, passengers using folding seats, and baggage all have selected seats, i.e., the row number and row number of passengers who have selected seats are known. Correspondingly, passengers who have not selected seats have not selected seats, so the row number and row number of passengers who have not selected seats are unknown.

[0031] Generally, the passenger data of the target flight can be retrieved from the departure system based on the airline, flight number, and departure date, and the reference basis for calculating the influence index of the target flight's passenger gravity center is obtained by collecting passenger data before the target flight's door closes.

[0032] In S102, static data of the aircraft and static data of the airline of the flight to be measured are obtained from a pre-set database. Here, the pre-defined database includes airline static data, aircraft formation static data, terminal static data, and aircraft static data for multiple flights. The static data of the airplane includes cabin layout information and passenger seat allocation rules. The cabin layout information includes the index of the center of gravity of each seat row.

[0033] The passenger seat allocation rules are as follows: for each seat row, multiple priorities are pre-set for the seats in the seat row, and the number of seats in each priority order is limited so that the sum of the numbers of seats in each priority order is equal to the number of seats in the seat row; the number of first seats in the seat row is counted to obtain the number of first seats in the seat row; if the number of first seats is less than the number of seats in the seat row, the seat row numbers and priorities of the second seats in the seat row are obtained; for the second seats in each seat row, the second seats are expressed as ascending seats in order of highest priority and lowest seat row number, and are allocated to unselected passengers; and the second seats are expressed as descending seats in order of highest priority and highest seat row number, and are allocated to unselected passengers.

[0034] Note that seat number 1 is the seat selected by the passenger, and seat number 2 is the seat not selected by the passenger. Generally, the seat row with the lower seat row number is located in front of the seat row with the higher seat row number.

[0035] In other words, the so-called passenger seat allocation rules are specifically set so that each seat row has four priority levels, and each priority level has a set number of seats. The sum of the seats in the four priority levels equals the total number of seats in that seat row. When allocating remaining seats, the system first checks whether the sum of the number of checked-in passengers and non-checked-in passengers who have selected seats is less than the number of seats in that seat row. If so, seats are allocated starting with the first priority level. Seats allocated to passengers who have not selected seats are first allocated by obtaining the remaining seats after checked-in passengers and non-checked-in passengers who have selected seats have selected their seats, and then allocating them in ascending order, i.e., from the front seats in the first priority level to the back seats. If the number of seats in the first priority level exceeds the number of passengers eligible for allocation (i.e., the number of passengers who have not selected seats), the remaining seats in each seat row in the first priority level are allocated sequentially. If the number of seats in the first priority is less than the number of passengers to be allocated, after the allocation from the front row to the back row in the first priority is completed, the allocation will continue in the second priority from the front row to the back row, and so on, until all unselected passengers have been allocated seats. Then, allocation will be in descending order, i.e., still starting from the first priority, but from the back row to the front row, and so on, similar to the allocation in ascending order, until all unselected passengers have been allocated seats.

[0036] In the embodiments of the present application, the so-called ascending order allocation method specifically means allocating each second seat to a passenger who has not yet selected a seat in descending order of priority and row number. The so-called descending order allocation method specifically means allocating each second seat to a passenger who has not yet selected a seat in descending order of priority and row number.

[0037] Specifically, taking the seat allocation scene shown in Figure 1c as an example, a, b, c, and d respectively represent four vacant seats with higher priority, and the subscripts 1 to n represent the corresponding seats in the nth row. n represents the vacant seat in row n with the first priority, and b nrepresents the vacant seat in row n with the second priority, and c n represents the vacant seat in row n in the third priority order, and d n represents the vacant seat in the nth row in the fourth priority order, and a n , b n , c n and d n The sum of these does not exceed the number of available seats in row n. Ascending order distribution starts from the first priority and distributes from row 1 to row n. Once the first priority seats have been distributed and there are any remaining passengers, it starts from the second priority and distributes from row 1 to row n, and so on. Descending order starts from the first priority and distributes from row n to row 1. Once the first priority seats have been distributed and there are any remaining passengers who have not selected a seat, it starts from the second priority and distributes from row n to row 1, and so on.

[0038] The airline's static data includes a passenger weight table. The passenger weight table includes weights for each passenger attribute. Specifically, the weight of an adult passenger, w adult , male passenger's weight w male , the weight of the female passenger w female , weight of child passenger w child , and the weight of the baby passenger w infant The passenger weight table is created by airlines by periodically weighing actual passengers and regularly updating the weights of adults, children and babies based on different routes, such as international flights and domestic flights. Naturally, it is also possible to distinguish between the weights of males and females for adults.

[0039] Specifically, the specific expression format of the passenger weight table can be seen in Table 1. [Table 1] The contents shown in Table 1 above are merely exemplary.

[0040] Specifically, the four priorities mentioned in the passenger seat distribution rules, the number of seats limited to each priority, and the index of the center of gravity of each seat row can be seen in Table 2. [Table 2] The contents shown in Table 2 above are merely exemplary.

[0041] In S103, the weight of the checked-in passenger is obtained from the passenger weight table based on the attributes of the checked-in passenger, and the influence index of the first center of gravity is calculated based on the seat row number of the checked-in passenger, the weight of the checked-in passenger, and the index of the center of gravity of the seat row selected by the checked-in passenger. Here, the specific implementation process of calculating the influence index of the first center of gravity based on the seat row number of the checked-in passenger, the weight of the checked-in passenger, and the index of the center of gravity of the seat row selected by the checked-in passenger can be referred to in equations (1), (2), and (3). In the embodiments of the present application, the influence index of the first center of gravity can be regarded as the influence index of the center of gravity of the checked-in passenger.

[0044] In the above formula (3), CG ch represents the influence index of the first centroid, n represents the number of checked-in passengers, and index j represents the index of the center of gravity of the jth seat row. Specifically, the seat row numbers of checked-in passengers and the index of the center of gravity of the seat row numbers selected by the checked-in passengers are shown in Table 3 as an example. [Table 3]

[0045] In addition, referring to the passenger weight table shown in Table 1, the total weight of the checked-in passengers in row 11 is 73×2+73×2+38×1=330KG, and the total weight of the checked-in passengers in row 12 is 73×1+73×1+10×1=156KG. The total weight of the checked-in passengers in row 12 is 73×1=73KG. Based on formula (3), the influence index of the first center of gravity of each seat row shown in Table 3 above is: The calculation is -0.007139×330+(-0.006367)×156+(-0.005605)×73=-3.758287. It should be noted that the above specific implementation process is merely an example.

[0046] In S104, based on the attributes of the passenger who has not checked in but selected a seat, the weight of the passenger who has not checked in but selected a seat is obtained from the passenger weight table, and the second center of gravity influence index is calculated based on the seat row number of the passenger who has not checked in but selected a seat, the weight of the passenger who has not checked in but selected a seat, and the index of the center of gravity of the seat row selected by the passenger who has not checked in but selected a seat. Here, the specific implementation process for calculating the influence index of the second center of gravity based on the seat row number of the passenger who has not checked in but selected a seat, the weight of the passenger who has not checked in but selected a seat, and the index of the center of gravity of the seat row selected by the passenger who has not checked in but selected a seat can be referred to in equations (4), (5) and (6). In the embodiment of the present application, the influence index of the second center of gravity can be regarded as the influence index of the center of gravity of the passenger who has not checked in but selected a seat.

[0050] Furthermore, as can be seen from the passenger weight table shown in Table 1, the average weight of passengers who have not checked in but have selected seats in rows 12, 13, and 14 is as follows: It could also be (73×(1+2)+73×(1+1+1)+10×1) / (1+2+1+1+1)=74.66666667KG. Based on equation (6), the influence index of the center of gravity of the 12th seat row is calculated as -0.006367×(1+1+1)×74.66666667=-4.278624, the influence index of the center of gravity of the 13th seat row is calculated as -0.005605×1×74.66666667=-0.41850667, and the influence index of the center of gravity of the 14th seat row is calculated as -0.004834×(2+1)×74.66666667=-1.084832. Therefore, the influence index of the second center of gravity for each seat row shown in Table 4 above is: -4.278624+(-0.41850667)+(-1.084832)=-5.781963. It should be noted that the above specific implementation process is merely an example.

[0051] In S105, seats are allocated to passengers who have not selected seats based on the passenger seat allocation rules, and the seat row numbers and seat numbers of the passengers who have not selected seats are obtained. Here, seats are allocated to passengers who have not selected seats according to the seat allocation rules. After obtaining the row numbers and seat numbers of the passengers who have not selected seats, the row numbers and seat numbers of the passengers who have not selected seats are known, and the row and seat numbers selected by the passengers who have not selected seats can be determined.

[0052] Specifically, we assume the number of passengers with different passenger attributes who have not selected seats, as shown in Table 5. [Table 5]

[0053] In addition, taking the passengers who have not selected seats shown in Table 5 as an example, seats can be allocated to the passengers who have not selected seats according to the passenger seat allocation rules, and the seat row numbers of the passengers who have not selected seats can be obtained, and Table 6 can be referred to. [Table 6] It should be noted that the contents shown in Tables 5 and 6 above are merely examples.

[0054] In S106, the weight of the passenger who has not selected a seat is obtained from the passenger weight table based on the attributes of the passenger who has not selected a seat, and the influence index of the third center of gravity is calculated based on the seat row number of the passenger who has not selected a seat, the weight of the passenger who has not selected a seat, and the index of the center of gravity of the seat row selected by the passenger who has not selected a seat. Here, the specific implementation process for calculating the influence index of the third center of gravity based on the row number of the passenger who has not selected a seat, the weight of the passenger who has not selected a seat, and the index of the center of gravity of the row selected by the passenger who has not selected a seat can be referred to in equations (7), (8), (9), (10), and (11). In the embodiments of the present application, the influence index of the third center of gravity can be regarded as the influence index of the center of gravity of the passenger who has not selected a seat.

[0058] Note that there may be overbooked seats on a flight. For example, the aircraft layout of a flight is F8Y120, but the actual number of reserved seats is F5Y122. Therefore, the two overbooked passengers in cabin Y need to be upgraded to cabin F. The seat allocation for the upgraded passengers will be the same as the passenger seat allocation rules mentioned above, and the calculation will be based on the same rules. In other words, the upgraded passengers will be treated as passengers who have not selected seats, and seats will be allocated accordingly.

[0059] Specifically, let us take the example of passengers who have not selected seats shown in Table 5 and assume that seats need to be distributed among 20 passengers who have not selected seats. First, seats are allocated in ascending order, starting with the first priority and then allocated from row 11 to row 18. 1 + 3 × 4 = 13 seats remain in all rows of the first priority. After the remaining seats in the first priority are allocated, eight passengers remain who have not selected a seat, and the priority is increased accordingly. Since there are no vacant seats in the second and third priority rows, seats in the fourth priority row are allocated. One seat in row 11, two in row 12, three in row 13, and two in row 14 can be allocated, completing the seat allocation for all passengers who have not selected a seat. The seat allocation results obtained using the ascending allocation method are shown in Table 7. Based on the passenger weight table shown in Table 1, the seat allocation results shown in Table 7, and Equation (7), the weight allocation results obtained are shown in Table 8.

[0060] [Table 7]

[0061] [Table 8]

[0062] Based on the number of passengers who have not selected seats in each seat row shown in Table 7, the total weight of passengers who have not selected seats in each seat row shown in Table 8, and equation (9), the influence index of the center of gravity in ascending order of each seat row shown in Table 6 is: Calculate as 69.5×(-0.007139)+139×(-0.004834)+...+208.5×0.000779=-5.347886.

[0063] Next, using the descending order allocation method, starting with the first priority, seats are allocated from row 18 to row 11, leaving 1 + 3 × 4 = 13 seats in all rows of the first priority. After the remaining seats in the first priority are allocated, eight passengers remain who have not selected a seat, and the priority is increased accordingly. Since there are no vacant seats in the second and third priority levels, seats in the fourth priority level are allocated, and three seats in row 18, three in row 17, and two in row 16 can be allocated, completing the seat allocation for all passengers who have not selected a seat. The seat allocation results obtained using the descending order allocation method are shown in Table 9.

It is well known in the aviation industry that stretcher passengers always occupy multiple seat rows. In the present embodiment, the number of seat rows selected by the stretcher passenger can be determined based on the seat row number of the stretcher passenger.

[0069] The preset weight distribution rule may be to distribute the weight of the stretcher passenger equally among the seat rows to ensure that the weight gained in each seat row is the same, and to distribute the excess weight sequentially among the seat rows in ascending order of the seat row number.

[0070] In S108, the fourth center of gravity influence index is calculated based on the seat row number of the stretcher passenger, the weight of each seat row selected by the stretcher passenger, and the center of gravity index of the seat row selected by the stretcher passenger.

The weight of stretcher passenger 1 is evenly distributed among seats in rows 14-16, and after distributing 66 kg to each seat row, 2 kg remains. Then, row 14 is increased by 1 kg, and row 15 is increased by 1 kg. Finally, rows 14-16 are distributed with 67 kg, 67 kg, and 66 kg, respectively.

The end row is the seat row with the largest seat row number among the seat rows selected by the stretcher passenger. Similarly, after evenly distributing the weight of stretcher passenger 2, ensuring that each seat row weighs 150 kg, the weight of each seat row selected by the stretcher passenger is obtained and is shown in Table 12.

[0096] Based on the flow shown in S101 to S112 above, this embodiment can achieve the following three beneficial effects.

[0097] Regarding resource allocation for loading management, the conventional loading process requires only a small amount of passenger check-in data to be acquired initially, and a cargo loading method must be developed to estimate cargo loading based on this limited data and prior experience. This method not only relies too much on human experience, but also carries the risk of inaccurate predictions. In contrast, this embodiment estimates the passenger center of gravity in real time during loading, reducing labor costs and improving the accuracy of the estimation.

[0098] Regarding service demand, even though the seat locations of many passengers are unknown from the flight loading process, the device can begin to estimate the passenger center of gravity, allowing for more effective guidance in cargo loading. Finally, when the center of gravity needs to be adjusted after all passengers have checked in, it is necessary to further adjust the center of gravity by adjusting the cargo in the cargo hold. This embodiment can significantly reduce the probability of adjusting the cargo. Moreover, reducing the probability of adjusting the cargo in the cargo hold also reduces the probability of flight delays.

[0099] Regarding the calculation method, the core of this embodiment is to allocate seats to passengers who have not yet selected a seat, and by setting multiple priorities, based on two methods, ascending and descending distribution, the average of the center of gravity influence indexes of the two distribution methods is used as the third center of gravity influence index, fully expressing the balance concept of loading operations. Moreover, an optimal matching calculation method is also adopted for other types of passengers. The passenger seat allocation method adopted in this embodiment is a groundbreaking invention, and has been verified through actual cases to be effective and meet expectations.

[0100] As described above, this embodiment determines the influence index of the center of gravity of the passengers who have selected seats based on the row numbers, weights, and center of gravity indexes of the selected row of passengers; allocates seats to passengers who have not selected seats; obtains the row numbers of the passengers who have not selected seats; determines the influence index of the center of gravity of the passengers who have not selected seats based on the row numbers, weights, and center of gravity indexes of the selected row of passengers; and determines the passenger center of gravity of the flight being measured based on the influence indexes of the center of gravity of the passengers who have selected seats and the passengers who have not selected seats. Obviously, the row numbers, weights, and center of gravity indexes of the selected row of passengers who have not selected seats are used as reference. Compared with the prior art, this embodiment can more efficiently and accurately calculate the passenger center of gravity of the flight being measured.

[0105] In S203, seats are allocated to passengers who have not selected seats, and the seat row numbers of the passengers who have not selected seats are obtained.
