Description

Technical Field

[0001] This application belongs to the field of air transportation, and particularly relates to a method and device for real-time measurement of the weight of flight passengers and their luggage. Background Art

[0002] The weight of passengers and their luggage involved in aircraft load and balance calculation is one of the core data of the load operation. In the "Regulations on Aircraft Weight and Balance Control" AC-121-FS-135 issued by the Civil Aviation Administration, four methods such as standard average weight and actual weight are detailed for determining the weight of passengers and luggage. However, the document mentions that "among them, the method of actual weight has the most accurate statistical data, but there may be operational difficulties during operation."

[0003] The invention patent CN115630833B discloses a method and related equipment for predicting checked baggage information of passengers. This patent predicts the weight of flight baggage based on the weight of checked baggage, but only involves the checked baggage of passengers and does not involve the weight of carry-on baggage of passengers.

[0004] Currently, there is no method and system for determining the real-time weight of passengers and luggage in domestic airports. Therefore, in a method and device for estimating the center of gravity of flight passengers disclosed in the invention patent CN115147023B, the passenger weight used is the average value obtained from national statistical data. However, there are significant differences in the body weights of passengers in the north and south regions of China, and there are also significant differences among passengers on different flights, resulting in a large deviation between the actual weight and the average value of statistical data. The center of gravity data of passengers obtained in this way will deviate greatly, which is very likely to affect the safety of flight operation.

[0005] Therefore, how to measure the weight of passengers and their carry-on baggage in real time to improve the accuracy of passenger center of gravity calculation and the accuracy of flight load, and develop a method and device for real-time measurement of the weight of flight passengers and their luggage is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0006] The purpose of this application is to disclose a method and device for real-time measurement of the weight of flight passengers and their luggage to solve the problem that the weight of flight passengers and their luggage cannot be measured in real time by overcoming the problems of the prior art.

[0007] The purpose of this application is achieved by the following technical solutions:

[0008] A method for real-time measurement of the weight of flight passengers and their luggage, the method for real-time measurement of the weight of flight passengers and their luggage includes:

[0009] S11: Obtain the actual weight data of a single security check channel, including the partition weight data and their sum, namely weight1 and weight2 and weight1 + weight2, where the two weighing areas for measuring weight1 and weight2 are arranged horizontally facing the manual security check counter;

[0010] S12: Compare and verify the actual weight data of the passenger and luggage. Assume that passenger_W is the weight of the passenger including the small bag, and baggage_W is the weight of the large carry-on bag. There are three situations for the actual weight data obtained by the weighing platform:

[0011] First, the passenger actually stands at the weight1 position, and the large carry-on bag is placed at the weight2 position. The measurement data conforms to the actual situation, that is, the weights of the passenger, luggage, and total weight are respectively

[0012] weight1 = passenger_W, weight2 = baggage_W, weight = weight1 + weight2 =

[0013] passenger_W + baggage_W;

[0014] Second, the passenger actually stands at the weight2 position, and the large carry-on bag is placed at the weight1 position. The measurement data is contrary to the actual situation;

[0015] Third, the passenger actually stands at the weight1 position and the large carry-on bag is also placed at the weight1 position, or the passenger actually stands at the weight2 position and the large carry-on bag is also placed at the weight2 position. The measurement data does not conform to the actual situation;

[0016] For the second and third situations, the following method is used for correction and verification:

[0017] 1) Obtain the on-site image: Obtain the real-time on-site images of the passenger, luggage, and weighing equipment;

[0018] 2) Extract and cut the image: Extract the images of the passenger, luggage, and weighing equipment, and cut and divide the images into blocks;

[0019] 3) Obtain the positions: Obtain the relative positions of the passenger, luggage, and equipment;

[0020] 4) Judge the positions: Judge the actual positions where the passenger stands and the luggage is placed according to the relative positions;

[0021] 5) Calculate the data:

[0022] For the second case, the values of weight1 and weight2 are corrected in real time. Then, the weight of the passenger, the weight of the luggage, and the total weight are respectively weight2 = passenger_W, weight1 = baggage_W, and weight = weight1 + weight2 = passenger_W + baggage_W;

[0023] For the third case, the value of weight1 or weight2 is taken, that is, the total weight weight = weight1 or weight2 = passenger_W + baggage_W;

[0024] S13: Match the obtained actual weight data with the passenger information;

[0025] S14: Obtain the actual weight data of passengers for all security check channels;

[0026] S15: Obtain the actual weight data of all boarding passengers on the flights preset by the airline;

[0027] S16: Process the weight data of special passengers according to the actual boarding situation of the flight. Special passengers include: infants or children, disabled passengers, overweight passengers, VIP passengers;

[0028] S17: Summarize and obtain the weight data of the actual boarding passengers on the flight;

[0029] S18: Calculate the weight and weight index of the actual boarding passengers on the flight, and complete the overweight assessment of the flight according to the weight index;

[0030] Among them, the actual weight of passengers on the flight is W 1 ,

[0031]

[0032] n represents the total number of passengers, and W i represents the boarding weight of passengers, including the weight of passengers and the weight of luggage;

[0033] Then, calculate the standard passenger weight W 2 of the flight according to the age and other conditions of the passengers. The standard passenger weight is as follows:

[0034] Passenger type Average passenger weight kg Number of passengers Adult passengers 75 X1 Children (aged 2 to under 12 years old) 35 X2 Infants (under 2 years old) 10 X3

[0035] W 2 = 75×X 1 + 35×X 2 + 10×X 3

[0036] The weight index Index is:

[0037]

[0038] According to a preferred embodiment, in step S12, for the second and third cases, when performing correction verification, for the scenario without a camera,

[0039] it is assumed that passenger_W is the weight of the passenger with a small bag, and baggage_W is the weight of the large carry-on suitcase.

[0040] For the second case, if weight1 is much greater than weight2 and weight2 is less than 10, then it is determined that weight1 = passenger_W and weight2 = baggage_W; if weight2 is much greater than weight1 and weight1 is less than 10, then it is determined that weight2 = passenger_W and weight2 = baggage_W.

[0041] For the third case, if weight1 = 0 and weight2 is greater than 0, then it is determined that passenger_W + baggage_W = weight2; if weight1 is greater than 0 and weight2 = 0, then it is determined that passenger_W + baggage_W = weight1.

[0122] Example 1

[0123] Reference Figure 1 As shown, a method for real-time measurement of the weight of flight passengers and luggage is shown in the figure. The method for real-time measurement of the weight of flight passengers and luggage includes the following steps.

[0124] Step S11: Obtain the actual weight data of a single security check channel. The actual weight data includes, but is not limited to, the weight of passengers (including small bags), the weight of a 20-inch carry-on suitcase, the weight of a large hiking bag, the weight of other sized carry-on boxes, etc. The actual weight data varies dynamically with individual differences among passengers and different personal luggage. Generally, the weights of passengers and luggage will be calculated separately, and if the situation is special, the total weight will be calculated.

[0125] The actual weight data includes the partition weight data and its data sum, that is, weight1 and weight2 and weight1 + weight2. That is, the two weighing areas for measuring weight1 and weight2 are arranged horizontally facing the manual security check counter.

[0126] Step S12: Compare and verify the actual weight data of passengers and luggage. Assume that passenger_W is the weight of the passenger including the small bag, and baggage_W is the weight of the large carry-on bag. There are three situations for the actual weight data obtained by the weighing platform:

[0127] First, the passenger actually stands at the weight1 position, and the large carry-on bag is placed at the weight2 position. The measurement data conforms to the actual situation, that is, the weights of the passenger, luggage, and total weight are respectively

[0128] weight1 = passenger_W, weight2 = baggage_W, weight = weight1 + weight2 =

[0129] passenger_W + baggage_W;

[0130] Second, the passenger actually stands at the weight2 position, and the large carry-on bag is placed at the weight1 position. The measurement data is contrary to the actual situation;

[0131] Third, the passenger actually stands at the weight1 position and the large carry-on bag is also placed at the weight1 position, or the passenger actually stands at the weight2 position and the large carry-on bag is also placed at the weight2 position. The measurement data does not conform to the actual situation;

[0132] For the second and third situations, the following method is used for correction and verification:

[0133] 1) Obtain on-site images: Obtain real-time on-site images of passengers and luggage and weighing equipment;

[0134] 2) Extract the cut images: Extract the images of passengers, luggage, and weighing equipment, and cut and divide the images into blocks;

[0135] 3) Obtain the positions: Obtain the relative positions of the passenger, luggage, and equipment;

[0136] 4) Determine the positions: Determine the actual positions where the passenger stands and the luggage is placed based on the relative positions;

[0137] 5) Calculate the data:

[0138] For the second case, correct the values of weight1 and weight2 in real time. Then, the weight of the passenger, the weight of the luggage, and the total weight are respectively weight2 = passenger_W, weight1 = baggage_W, and weight = weight1 + weight2 = passenger_W + baggage_W;

[0139] For the third case, take the value of weight1 or weight2, that is, the total weight weight = weight1 or weight2 = passenger_W + baggage_W.

[0140] Preferably, in step S12, for the second and third cases, when performing correction verification, for the scenario without a camera, assume that passenger_W is the weight of the passenger including a small bag, and baggage_W is the weight of a large handbag;

[0141] For the second case, if weight1 is much greater than weight2 and weight2 is less than 10, then determine that weight1 = passenger_W and weight2 = baggage_W; if weight2 is much greater than weight1 and weight1 is less than 10, then determine that weight2 = passenger_W and weight2 = baggage_W.

[0142] For the third case, if weight1 = 0 and weight2 > 0, then determine that passenger_W + baggage_W = weight2; if weight1 > 0 and weight2 = 0, then determine that passenger_W + baggage_W = weight1.

[0143] Step S13: Match the obtained actual weight data with the passenger information.

[0144] Preferably, in step S13, the passenger information includes: airline, flight number, flight date, departure station, arrival station, cabin segment, seat number.

[0145] Step S13 includes: matching the weight data of each passenger, baggage weight, and registration weight data of a preset security check channel with the passenger information one by one to form a first data list; wherein, the passenger weight is passenger_W, the baggage weight is baggage_W, and the registration weight is passenger_W + baggage_W. An example of the first data list is as follows.

[0146]

[0147] Step S14: Obtain the actual weight data of passengers for all security check channels.

[0148] Step S14 includes: continuously merging the corresponding first data lists of each security check channel obtained in real time, so as to obtain the actual weight data of passengers for all security check channels and form a second data list. An example of the second data list is as follows.

[0149]

[0150] Step S15: Obtain the actual weight data of all boarding passengers for a preset flight of an airline.

[0151] Preferably, step S15 includes: at the cut-off time, according to the obtained second data list, extract the information of all security check passengers for a preset flight of a preset airline to form a third data list, and classify and mark each passenger, and ordinary passengers are marked as 1. An example of the third data list is as follows.

[0152]

[0153] Step S16: Process the weight data of special passengers according to the actual boarding situation of the flight. Special passengers include: infants or children, disabled passengers, overweight passengers, VIP passengers.

[0154] Preferably, in step S16, the process of processing the weight data of special passengers and forming a fourth data list includes:

[0155] 1) For infant or child passengers

[0156] After obtaining the passenger image at the security checkpoint according to the ticket information, make a judgment: If the passenger is carried by his or her companion, record the weight of the passenger as 0 and add the weight to the boarding weight of the companion passenger; If the child passenger stands independently, record his or her actual weight; If the child passenger stands together with the luggage, add his or her weight to the boarding weight of the companion passenger, record the weight of the passenger as 0 at the same time, and mark the child passenger as 2.

[0157] 2) For disabled passengers

[0158] For disabled passengers in wheelchairs, if they agree to be measured, measure them together with the wheelchair, subtract the weight of the wheelchair uniformly provided by the airport from the measurement data, and mark 30 in the data at the same time; If they refuse to be measured, assign their weight to the average value and mark 31;

[0159] And while measuring the weight of disabled passengers, identify them through images, distinguish the areas of the images of passengers, accompanying personnel and wheelchairs, so as to obtain the true situation of wheelchair passengers and prevent misjudgment;

[0160] 3) For overweight passengers

[0161] For passengers whose weight exceeds the preset value, confirm with the on-site images extracted in real time to prevent misjudging the weight as the sum of the weight and the luggage weight, and mark 4 in the data;

[0162] 4) For VIP passengers

[0163] For VIP passengers who do not pass through the ordinary security channel, since there is no weight measurement data, according to the check-in information, assign the corresponding passengers the statistical average value and mark 5.

[0164] Step S17: Summarize and obtain the weight data of the actual passengers on the flight.

[0165] Preferably, in step S17, for the preset flight, summarize the corresponding third data list and fourth data list to form the fifth data list of the weight data of the actual passengers on the corresponding flight. An example of the fifth data list is as follows.

[0166]

[0167] Step S18: Calculate the weight and weight index of the actual passengers on the flight, and complete the overweight assessment of the flight according to the weight index; Specifically, perform calculation processing according to the fifth data list obtained in step S17.

[0168] Among them, the actual weight of the flight passengers W 1 ,

[0169]

[0170] n represents the total number of passengers, and W i represents the boarding weight of passengers, including the weight of passengers and luggage;

[0171] Then, calculate the standard passenger weight W of the flight according to the passenger age and other conditions 2 , where the standard passenger weight is as follows:

[0172] Passenger type Average passenger weight kg Number of passengers Adult passengers 75 X1 Children (aged 2 to under 12 years old) 35 X2 Infants (under 2 years old) 10 X3

[0173] W 2 = 75×X 1 + 35×X 2 + 10×X 3

[0174] The weight index Index is:

[0175]

[0176] The value of Index can be used to evaluate whether the flight is overweight to prevent safety situations, etc. If the value of Index is less than 1, it means that the actual passenger weight of the flight is less than the standard passenger weight of the flight; if the value of Index is equal to 1, it means that the actual passenger weight of the flight is equal to the standard passenger weight of the flight; if the value of Index is greater than 1, it means that the actual passenger weight of the flight is greater than the standard passenger weight of the flight.

[0177] Embodiment 2

[0178] This embodiment discloses: A method for real-time measurement of the weight of flight passengers and luggage, and the method for real-time measurement of the weight of flight passengers and luggage includes the following steps.

[0179] Step S21: Obtain the actual weight data of a single express channel. The actual weight data of a single express channel is the average of the front and rear partition weight data, that is, (weight1 + weight2) / 2. At this time, it is assumed that passengers and luggage pass through a certain weighing platform module at the same time. At this time, the total weight of passengers and luggage is (weight1 + weight2) / 2.

[0180] Step S22: Compare and verify the actual weight data of passengers and luggage. Assume that passenger_W is the weight of the passenger including the small bag, and baggage_W is the weight of the large carry-on suitcase

[0181] When passengers and luggage do not pass through a certain weighing platform at the same time, that is, passengers and luggage pass through the weighing platform of the express security channel in sequence, as Figure 4 shown.

[0182] If weight1 is much greater than weight2 and weight2 is less than 10, then it is determined that weight1 = passenger_W and weight2 = baggage_W; if weight2 is much greater than weight1 and weight1 is less than 10, then it is determined that weight2 = passenger_W and weight1 = baggage_W.

[0183] Step S23: Match the obtained actual weight data with the passenger information. Step S24: Obtain the actual weight data of passengers for all security check channels. Step S25: Obtain the actual weight data of all boarding passengers for the flights preset by the airline. Steps S23 to S25 are the same as the corresponding methods in Embodiment 1.

[0184] Step S26: Process the weight data of special passengers according to the actual boarding situation of the flight. Special passengers include: infants or children, disabled passengers, overweight passengers, and VIP passengers.

[0185] Preferably, in step S26, the process of processing the weight data of special passengers and forming a fourth data list includes:

[0186] 1) For infants or children

[0187] After obtaining the passenger image at the security checkpoint according to the ticket information, make a judgment: if the corresponding passenger is carried by their companion, record the weight of the corresponding passenger as 0 and add its weight to the boarding weight of the companion passenger; if the corresponding passenger walks independently, record their actual weight; if the corresponding passenger rides in a stroller, the weight of the corresponding passenger is the measured data minus the weight of the stroller. The weight of the stroller is the average weight Wy of the visible models on the market, and the infant or child passenger is marked as 2.

[0188] 2) For disabled passengers

[0189] For disabled passengers in wheelchairs, measure them together with the wheelchair and subtract the weight W of the wheelchair uniformly provided by the airport from the measured data l , and at the same time mark it as 30 in the data;

[0190] And, during the weight measurement, identify through images, and distinguish the passengers, wheelchairs, and accompanying personnel in different regions of the image to obtain the true situation of wheelchair passengers and prevent misjudgment;

[0191] 3) For overweight passengers

[0192] For passengers whose weight exceeds the preset value, confirm by combining the on-site images extracted in real time to prevent misjudging the weight as the sum of the weight and the baggage weight, and mark it as 4 in the data;

[0193] 4) For VIP passengers

[0194] For VIP passengers who do not pass through the ordinary security check channel, since there is no weight measurement data, according to the check-in information, the corresponding passengers are given the statistical average value and marked as 5;

[0195] For infant or child passengers and disabled passengers, in the fast security check channel, it is a dynamic moving process. When the accompanying person pushes a baby stroller or wheelchair, a force will be applied to the baby stroller or wheelchair through the handle. When calculating, the measured value is given a certain coefficient λ. λ is obtained by simulating the scenario of passengers passing through the device to accumulate a certain amount of data and then calculating the average value.

[0196] For passengers pushing baby strollers:

[0197]

[0198] For passengers pushing wheelchairs:

[0199]

[0200] Step S27: Summarize and obtain the weight data of the actual boarding passengers on the flight; S28: Calculate the weight and weight index of the actual boarding passengers on the flight, and complete the overweight assessment of the flight according to the weight index. Steps S27 to S28 are the same as the corresponding methods in Embodiment 1.
