Description

Estimation method and device for flight passenger center of gravity

This application claims priority to the Chinese patent application submitted to the China Patent Office on September 5, 2022, with the application number 202211076577.1 and the invention title "Estimating Method and Device for Flight Passenger Center of Gravity", the entire content of which is incorporated into this application by reference. middle.

Technical field

This application relates to the field of aviation information, and in particular to a method and device for estimating the center of gravity of flight passengers.

Background technique

High safety is the basic prerequisite and important guarantee for aircraft to take off on time. It is also the lofty mission and responsibility of the civil aviation industry. Aircraft load and balance are the core links to ensure high safety. It effectively controls the center of gravity of the aircraft by rationally allocating passenger seats and cargo spaces, so that the center of gravity of the aircraft is within the safe center of gravity range, thereby ensuring the flight safety of the aircraft.

The calculation of the passenger center of gravity of a flight is a key step in the calculation process of the aircraft center of gravity. The passenger center of gravity estimation device for loaded flights is a device that estimates the passenger center of gravity without fully obtaining passenger data. It is an important support and guarantee for the flight to take off on time. Effective protection. Because aircraft stowage operations often begin some time before the flight takes off, flight passengers may be in various unknown states during this process, such as booking a seat when purchasing a ticket but not checking in, or not reserving a seat when purchasing a ticket, etc. Passengers have not selected a seat. Or not checking in means the uncertainty of the final passenger's seat selection. During this period, the aircraft will allocate and load cargo from the cargo system, and the important basis for the cargo distribution plan in the cargo hold is the passenger center of gravity. The calculation of the passenger center of gravity of a flight is mainly related to the passenger's weight and seat row. If the center of gravity calculation is performed until all passengers have checked in, it will inevitably delay the loading of cargo and cause flight delays.

During the loading process of the current flight, since it is impossible to estimate the center of gravity of the passenger flight, we can only rely on the acquired passenger data to make preliminary calculations, then load the cargo based on this calculation result and past experience, and finally wait for all passengers to complete check-in. Finally, if the center of gravity needs to be adjusted, the correction is made by adjusting the position of the cargo in the cargo hold. This method may cause a certain degree of demand for cargo adjustment due to the lack of estimation of the passenger's center of gravity. The more accurate the passenger center of gravity is, the better the cargo loading plan will be. In this way, through adjustment, the cargo loading plan will be better. The probability of cargo adjustment will be greatly reduced.

For this reason, how to accurately predict the center of gravity of flight passengers has become an urgent problem that needs to be solved in this field.

As shown in Figure 1a and Figure 1b, it is a schematic flow chart of a method for estimating the center of gravity of flight passengers provided by the embodiment of the present application, including the following steps:

S101: Obtain the passenger data of the flight to be tested from the departure system.

Among them, passenger data includes passenger attributes and seat attributes of each passenger. Each type of passenger includes passengers who have selected a seat and passengers who have not selected a seat. Passengers who have selected a seat include passengers who have checked in, passengers who have not checked in but have selected a seat. Passengers, stretcher passengers, extra seat-occupying items, jump seat passengers (commonly known as crew folding seat passengers), and hand luggage. In addition, the seat attributes include the seat row number and seat number of the passenger who has selected a seat.

In the embodiment of the present application, stretcher passengers represent passengers who are unable to move and need to arrange multiple seats. Extra seat-occupying items represent valuable items carried by passengers and require a separate seat arrangement. Crew folding seat passengers represent passengers who purchase preset crew folding seats. Carry-on baggage represents the baggage carried by the passenger, and the baggage is stored above the passenger's seat.

In addition, the types of passenger attributes include adult passengers, male passengers, female passengers, child passengers, and infant passengers. Generally speaking, the seat row number indicates the seat row selected by the passenger, and the seat number indicates the seat selected by the passenger. The so-called seat row refers to a pre-configured seat combination in a flight. The flight will be pre-configured with multiple seat rows, and each seat row includes multiple seats.

Checked-in passengers, passengers who have not checked in but have selected seats, passengers on stretchers, passengers with extra seat-occupying items, passengers with foldable seats on the crew, and carry-on baggage have all selected seats, that is, the seat row and seat number of passengers who have selected seats are known of. Correspondingly, the passenger who has not selected a seat has not yet selected a seat. Therefore, the seat row number and seat number of the passenger who has not selected a seat are unknown.

Generally speaking, the passenger data of the flight to be tested can be searched from the departure system using the airline, flight number and departure date as the search basis. Before the flight to be tested is closed, the passenger gravity impact index of the flight to be tested is calculated as a reference. The basis is all derived from collecting passenger data.

S102: Obtain aircraft static data and airline static data of the flight to be tested from the preset database.

Among them, the preset database includes airline static data, fleet static data, terminal static data and aircraft static data of multiple flights.

It should be noted that the aircraft static data includes cabin layout information and passenger seat allocation rules.

Cabin layout information includes the center of gravity index for each row of seats.

The passenger seat allocation rule is: for each seat row, set multiple priorities for the seats in the seat row in advance, and limit the number of seats for each priority so that the sum of the number of seats for each priority is equal to the number of seats in the seat row. ; Count the number of first seats included in the seat row and obtain the number of first seats in the seat row; when the number of first seats is less than the number of seats in the seat row, obtain the seat row number of the second seat included in the seat row and priority; for the second seats included in each seat row, each second seat is marked as a positive seat in the order of priority from high to low and in order of seat row number from small to large. First-order seats are allocated to each passenger who has not selected a seat; in order of priority from high to low and seat number from large to small, each second seat is marked as a reverse-order seat and allocated to each passenger who has not selected a seat.

It should be noted that the first seat represents the seat that has been selected by the passenger, and the second seat represents the seat that has not been selected by the passenger. Generally speaking, the seat row with the smaller seat number is usually arranged before the seat row with the larger seat number.

In other words, the so-called passenger seat allocation rules can be understood as follows: Each row of seats is preset to have 4 priorities, and the number of seats is set for each priority. The sum of the number of seats in the 4 priorities is equal to the number of seats in that row. The total number of seats. When allocating the remaining seats, first check whether the sum of checked-in passengers in this seat row and passengers who have not checked in but have selected seats is less than the number of seats in this row. If it is less, then allocate it from the first priority. To allocate passengers who have not selected seats, you need to first obtain the remaining seats after checking in and passengers who have not checked in but have selected seats, and then allocate them in the correct order, that is, from the front row to the back row in the first priority level. Assignment, if the number of seats in the first priority class exceeds the number of passengers to be allocated (that is, the number of passengers who have not selected seats), the remaining seats in each row of the first priority class will be allocated directly in sequence. If the number of seats in the first priority class is less than The number of passengers to be allocated will be allocated from the front row to the back row in the first priority level, and then continue to be allocated in the second priority level from the front row to the back row, and so on, until all passengers who have not selected seats have been allocated seats. , and then allocate in reverse order, that is, still starting from the first priority, but starting from the back row to the front row, and other allocations are similar to the forward order, until all passengers who have not selected seats have been allocated seats.

In the embodiment of this application, the so-called positive sequence allocation method specifically refers to: allocating each second seat to each unselected passenger in the order of priority from high to low and seat number from small to large. . The so-called reverse order allocation method specifically refers to allocating each second seat to each passenger who has not selected a seat in the order of priority from high to low and seat number from large to small.

Specifically, taking the seat allocation scenario shown in Figure 1c as an example, a, b, c and d respectively represent four priority vacant seats, the subscripts 1 to n represent the corresponding nth row of seats, and a _n represents the nth row. The vacant seats in the first priority class, b _n represents the vacant seats in the nth row and the second priority class, c _n represents the vacant seats in the nth row and the third priority class, d _n represents the vacant seats in the nth row of seats. For priority 4 available seats, the sum of a _n , b _n , c _n and d _n shall not exceed the number of available seats in the nth row. Forward allocation means starting from priority 1, from row 1 to row n. If there are remaining passengers after all the empty seats in priority 1 are allocated, it will start from priority 2, and continue from row 1 to row n. The allocation starts from the nth row, and so on. The reverse order starts from the 1st priority, and starts to be allocated from the nth row to the 1st row. If the 1st priority has been allocated, After that, if there are still passengers who have not selected seats to be allocated, they will start from the 2nd priority, and continue to be allocated from the nth row to the 1st row, and so on.

The airline's static data includes a passenger weight table. The passenger weight table includes the weight of each passenger attribute. Specifically, it includes the weight of adult passengers w ^adult , the weight of male passengers w ^male , the weight of female passengers w ^female , and the weight of child passengers w ^child , the weight of the infant passenger w ^infant . Passenger weight tables are regularly updated by airlines based on actual passenger weights, and regularly update the weights of adults, children and infants based on international flights, domestic flights and different routes. Of course, adults can also distinguish the weights of men and women.

Specifically, the specific expression form of the passenger weight table can be seen in Table 1.

Table 1

The contents shown in Table 1 above are only for illustration.

Specifically, assuming the four priorities mentioned in the passenger seat allocation rules, the number of seats limited to each priority, and the center of gravity index of each seat row, see Table 2.

Table 2

The contents shown in Table 2 above are only for illustration.

S103: According to the passenger attribute of the checked-in passenger, obtain the weight of the checked-in passenger from the passenger weight table, and calculate the weight of the checked-in passenger based on the seat number of the checked-in passenger, the weight of the checked-in passenger, and the seat arrangement selected by the checked-in passenger. The center of gravity index is calculated to obtain the first center of gravity influence index.

Among them, based on the seat row number of the checked-in passenger, the weight of the checked-in passenger, and the center of gravity index of the seat row selected by the checked-in passenger, the specific implementation process of calculating the first center of gravity impact index can be found in formula (1), (2) and (3) are shown. In the embodiment of this application, the first center of gravity impact index can be regarded as the center of gravity impact index of passengers who have checked in.

In the above formulas (1) and (2), represents the total weight of checked-in passengers in the jth row, n represents the number of adult passengers in the jth row, m represents the number of child passengers in the jth row, and k represents the number of children in the jth row. The number of infant passengers who are check-in passengers, t represents the number of female passengers who have checked in in the jth row, h represents the number of male passengers who have checked in in the jth row, w ^adult represents the checked-in passengers whose passenger attributes are adult passengers The weight of the passenger, w ^male represents the weight of the checked-in passenger whose passenger attribute is a male passenger, w ^female represents the weight of the checked-in passenger whose passenger attribute is a female passenger, and w ^child represents the weight of the checked-in passenger whose passenger attribute is a child passenger. Weight, w ^infant represents the weight of checked-in passengers whose passenger attributes are infant passengers.

In the above formula (3), CG _ch represents the first center of gravity influence index, n represents the number of checked-in passengers, and index _j represents the center of gravity index of the j-th seat row.

Specifically, take the seat row number of the checked-in passenger and the center of gravity index of the seat row selected by the checked-in passenger shown in Table 3 as an example:

table 3

Referring to the passenger weight table shown in Table 1, we can see that the total weight of the checked-in passengers in the 11th row is 73×2+73×2+38×1=330KG; the total weight of the checked-in passengers in the 12th row is 73×1+73×1+10×1=156KG; the total weight of checked-in passengers in row 12 is 73×1=73KG; further calculated according to formula (3), the weight of each seat row shown in Table 3 above The first center of gravity impact index is:

-0.007139×330+(-0.006367)×156+(-0.005605)×73=-3.758287.

It should be noted that the above specific implementation process is only for illustration.

S104: Based on the passenger attributes of the passengers who have not checked in but have selected their seats, obtain the weight of the passengers who have not checked in but have selected their seats from the passenger weight table, and based on the seat numbers and seat numbers of the passengers who have not checked in but have selected their seats, However, the second center of gravity impact index is calculated based on the weight of passengers who have selected seats and the center of gravity index of the seat row selected by passengers who have not checked in but have selected seats.

Among them, the second center of gravity impact index is calculated based on the seat row number of the passenger who has not checked in but has selected a seat, the weight of the passenger who has not checked in but has selected a seat, and the center of gravity index of the seat row selected by the passenger who has not checked in but has selected a seat. The specific implementation process can be found in formulas (4), (5) and (6). In the embodiment of this application, the second center of gravity impact index can be regarded as the center of gravity impact index of passengers who have not checked in but have selected seats.

^Nnoch ＝f+m+c (5)

In the above formulas (4) and (5), represents the average weight of passengers who have not checked in but have selected their seats, f represents the number of male passengers who have not checked in but have selected their seats, m represents the number of female passengers who have not checked in but have selected their seats, and c represents the number of female passengers who have not checked in but have selected their seats. The number of child passengers for seat selection passengers, i represents not yet checked in but has The number of infant passengers who select seats, w ^adult represents the weight of the passengers whose attributes are adult passengers who have not checked in but have selected their seats, w ^male represents the weight of the passengers whose attributes are male passengers who have not checked in but have selected their seats, and w ^female represents The passenger attribute is the weight of a female passenger who has not checked in but has selected a seat. w ^child represents the weight of a child passenger who has not checked in but has selected a seat. w ^infant represents the passenger attribute of an infant passenger who has not checked in but has selected a seat. The weight of passengers who have selected seats, N ^noch represents the number of passengers who have not checked in but have selected seats.

In the above formula (6), CG _noch represents the second center of gravity influence index, n represents the number of passengers who have not checked in but have selected seats, represents the number of passengers in row j who have not checked in but have selected seats, and index _j represents the center of gravity index of row j.

Specifically, take the seat row numbers of passengers who have not checked in but have selected their seats and the center of gravity index of the seat rows selected by passengers who have not checked in but have selected their seats shown in Table 4 as an example:

Table 4

Referring to the passenger weight table shown in Table 1, we can see that the average weight of passengers in rows 12, 13 and 14 who have not checked in but have selected seats can be:

(73×(1+2)+73×(1+1+1)+10×1)/(1+2+1+1+1)=74.66666667KG.

According to further calculation according to formula (6), the center of gravity influence index of the 12th row of seats is -0.006367×(1+1+1)×74.66666667=-4.278624; the influence index of the center of gravity of the 13th row of seats is -0.005605×1× 74.66666667=-0.41850667; the center of gravity impact index of the 14th row of seats is -0.004834×(2+1)×74.66666667=-1.084832;

To this end, the second center of gravity influence index of each seat row shown in Table 4 above is:

-4.278624+(-0.41850667)+(-1.084832)=-5.781963.

Resource allocation for stowage management: In the traditional stowage process, only a small amount of passenger check-in data is available at the beginning, and cargo loading needs to be estimated based on these limited data and prior experience. Making a cargo loading plan not only relies too much on human experience, but also runs the risk of inaccurate estimates. However, this embodiment estimates the passenger center of gravity in real time from the beginning of loading, which not only reduces labor costs, but also improves the estimation accuracy.

In terms of business needs: starting from the loading work of the flight, although the seats of many passengers are unknown, the device can begin to estimate the center of gravity of the passengers, and can more effectively guide the loading of cargo, avoiding the need to wait until all passengers have checked in. When the center of gravity needs to be adjusted, the center of gravity also needs to be adjusted by adjusting the cargo in the cargo hold. This embodiment can greatly reduce the probability of adjusting the cargo. At the same time, when the probability of adjusting cargo holds is reduced, the probability of flight delays is also reduced.

In terms of calculation rules: The core of this embodiment is to allocate seats to passengers who have not selected seats. By setting multiple priorities, assign them in forward order and in reverse order, and take the average of the center of gravity impact index of the two allocation plans as The third center of gravity impact index fully reflects the idea of balance in stowage work. At the same time, the best matching calculation method is also used for other types of passengers. The passenger seat allocation rule adopted in this embodiment is a breakthrough invention, which has been verified by examples to be effective and feasible, and is in line with expectations.

To sum up, this embodiment determines the center of gravity impact index of passengers who have selected seats based on the seat row number, weight, and center of gravity index of the selected seat row, and allocates seats to passengers who have not selected seats. The seat arrangement of passengers who have not selected a seat, and based on the seat arrangement, weight, and center of gravity index of the selected seat row, determine the impact index of the center of gravity of the passenger who has not selected a seat, based on the number of passengers who have selected a seat and the number of passengers who have not selected a seat Passengers' respective center of gravity influence index determines the passenger center of gravity of the flight to be tested.
