Description

Technical Field

[0001] This invention relates to the field of aviation technology, and in particular to a method, system, device and medium for intelligent control of water replenishment in aircraft. Background Technology

[0002] For airlines, flight costs are the largest expense in operating costs, and fuel costs are a significant component of flight costs. Fuel consumption during flight increases with aircraft payload. The greater the payload beyond the commercial load, the lower the economic efficiency of the flight.

[0003] In the existing technology, the aircraft water tanks are usually filled with water by a water supply truck before each flight. However, after most flights are over, there is a large amount of residual drinking water in the aircraft water tanks, which causes unnecessary waste of fuel and water resources. Summary of the Invention

[0004] This invention provides a method, system, device, and medium for intelligent control of aircraft water replenishment, to solve the problem of fuel and water resource consumption caused by the inability to intelligently control water supply trucks to replenish aircraft water tanks, thereby effectively reducing fuel and water costs.

[0005] To achieve the above objectives, embodiments of the present invention provide a method for intelligently controlling water replenishment in an aircraft, comprising:

[0006] Obtain the flight information of the flight to be launched and the remaining water level in the aircraft's water tank; the flight information includes the flight time, number of passengers, and aircraft type;

[0007] Based on the navigation information, calculate the target water consumption for the flight to be launched;

[0008] When the remaining water volume is lower than the target water consumption, a first command is sent to the booster pump of the water supply truck to start the booster pump to add water to the aircraft water tank;

[0009] The actual flow rate of the water supply truck is obtained, and the flow error compensation value is calculated based on the actual flow rate and the preset flow meter signal acquisition time interval; the amount of water to be added to the aircraft water tank is calculated based on the remaining water volume in the aircraft water tank, the target water consumption, and the flow error compensation value.

[0010] When the water output of the water supply truck equals the water filling volume of the aircraft water tank, a second command is sent to the booster pump to shut down the booster pump and end the water filling process.

[0011] As an improvement to the above scheme, the formula for calculating the target water consumption is as follows:

[0012] W total =T*N people*X+Y

[0013] Among them, W total The target water consumption for the flight to take off is represented by N; T represents the flight time of the flight to take off; people X represents the number of passengers on the flight to be launched; Y represents the flight coefficient of the aircraft type; and Y represents the reserved safety value of the water tank capacity of the aircraft type.

[0014] As an improvement to the above scheme, the flight coefficient is obtained through the following steps:

[0015] Obtain historical flight coefficient data for the most recent 30 completed flights;

[0016] The flight coefficient of the current flight is obtained by taking a weighted average of the historical flight coefficient data.

[0017] If the number of historical flights of a flight is less than thirty, the missing historical flight coefficient data will be replaced by the initial value of the flight coefficient.

[0018] As an improvement to the above scheme, the formula for calculating the reserved safety value is as follows:

[0019]

[0020] Where Y represents the reserved safety value of the water tank capacity of the aircraft model; Y0 represents the initial reserved safety value of the water tank capacity of the aircraft model; N people N represents the number of passengers on the flight to be launched. seat q represents the number of seats on the aircraft for the flight to be launched; q represents the step coefficient.

[0021] As an improvement to the above scheme, the step coefficient is determined based on the flight time of the flight to be launched. As the flight time of the flight to be launched increases, the value of the step coefficient increases. Specifically, when the flight time of the flight to be launched is greater than the preset flight time, the step coefficient is taken at its maximum value.

[0022] As an improvement to the above scheme, the formula for calculating the flow error compensation value is as follows:

[0023] Z = L * ΔT

[0024] Where Z represents the flow error compensation value; L represents the flow rate when the water supply truck discharges water; and ΔT represents the time interval for the flow meter to collect signals.

[0025] As an improvement to the above scheme, the formula for calculating the amount of water added is:

[0026] W add =W total -Wremain -Z

[0027] Among them, W add This indicates the amount of water added to the aircraft's water tank; W total This indicates the target water consumption for the flight to be launched; W remain Z represents the remaining water volume in the aircraft's water tank; Z represents the flow error compensation value.

[0028] To achieve the above objectives, embodiments of the present invention also provide a system for intelligently controlling aircraft water replenishment, comprising:

[0029] The data acquisition module is used to acquire the flight information of the flight to be launched and the remaining water level in the aircraft's water tank; the flight information includes the flight time, number of passengers and aircraft type.

[0030] The target water consumption calculation module is used to calculate the target water consumption of the flight to be launched based on the flight information.

[0031] The water filling module is activated to send a first command to the booster pump of the water supply truck when the remaining water volume is lower than the target water consumption, so as to start the booster pump to add water to the aircraft water tank;

[0032] The water volume calculation module is used to obtain the actual flow rate when the water supply truck discharges water, calculate the flow error compensation value based on the actual flow rate and the preset flow meter signal acquisition time interval, and calculate the water volume added to the aircraft water tank based on the remaining water volume in the aircraft water tank, the target water volume, and the flow error compensation value.

[0033] The water filling module is used to send a second command to the booster pump to shut down the booster pump and end the water filling process when the water output of the water supply truck is equal to the water filling of the aircraft water tank.

[0034] To achieve the above objectives, embodiments of the present invention also provide a device for intelligently controlling aircraft water replenishment, including a processor, a memory, and a computer program stored in the memory and configured to be executed by the processor, wherein the processor implements the above-described method for intelligently controlling aircraft water replenishment when executing the computer program.

[0035] To achieve the above objectives, embodiments of the present invention also provide a computer-readable storage medium, the computer-readable storage medium including a stored computer program; wherein, when the computer program is executed, it controls the device where the computer-readable storage medium is located to perform the above-described method for intelligently controlling aircraft water replenishment.

[0036] Implementing the embodiments of the present invention has the following beneficial effects:

[0037] The present invention provides a method, apparatus, device, and storage medium for intelligent control of aircraft water replenishment. First, it acquires the flight information of a flight awaiting takeoff and the remaining water volume in the aircraft's water tank. The flight information includes the flight time, number of passengers, and aircraft type. Then, based on the flight information, it calculates the target water consumption for the flight. When the remaining water volume is lower than the target water consumption, it sends a first command to the booster pump of the water supply truck to start the booster pump and replenish the aircraft's water tank. Next, it acquires the actual flow rate of the water supply truck and calculates a flow error compensation value based on the actual flow rate and a preset flow meter signal acquisition time interval. Then, it calculates the amount of water to be replenished in the aircraft's water tank based on the remaining water volume, the target water consumption, and the flow error compensation value. When the water supply truck's output equals the amount of water to be replenished in the aircraft's water tank, it sends a second command to the booster pump to shut off the booster pump and end the water replenishment process. Therefore, the embodiments of the present invention can realize intelligent control of the water filling process of aircraft water tanks, reduce human judgment errors, ensure the accuracy of water filling, provide sufficient water for cabin service, and minimize the amount of water left over, thereby saving fuel and water costs.

[0042] 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.

[0043] In the description of this invention, it should be noted that the step numbers in the text are only for the convenience of explaining the specific embodiments and are not intended to limit the order in which the steps are performed.

[0044] See Figure 1 , Figure 1This is a flowchart of a method for intelligently controlling aircraft water replenishment provided by an embodiment of the present invention. The method for intelligently controlling aircraft water replenishment includes steps S1 to S5, as detailed below:

[0045] S1. Obtain the flight information of the flight to be launched and the remaining water level in the aircraft's water tank; the flight information includes the flight time, number of passengers, and aircraft type;

[0046] S2. Calculate the target water consumption of the flight to be launched based on the navigation information;

[0047] S3. When the remaining water volume is lower than the target water consumption, a first command is sent to the booster pump of the water supply truck to start the booster pump to add water to the aircraft water tank.

[0048] S4. Obtain the actual flow rate when the water supply truck discharges water, and calculate the flow error compensation value based on the actual flow rate and the preset flow meter signal acquisition time interval; calculate the amount of water to be added to the aircraft water tank based on the remaining water volume in the aircraft water tank, the target water consumption, and the flow error compensation value.

[0049] S5. When the water output of the water supply truck is equal to the water filling volume of the aircraft water tank, a second command is sent to the booster pump to shut down the booster pump and end the water filling process.

[0050] In this embodiment of the invention, the flight information of the flight to be launched and the remaining water volume in the aircraft's water tank are first obtained. The target water consumption of the flight to be launched is dynamically and accurately calculated. Then, when the remaining water volume is lower than the target water consumption, a first command is sent to the booster pump of the water supply truck to start the booster pump to add water to the aircraft's water tank. The actual flow rate of the water supply truck and the preset flow meter signal acquisition time interval are obtained to calculate the flow error compensation value. Then, based on the remaining water volume of the aircraft's water tank, the target water consumption, and the flow error compensation value, the amount of water added to the aircraft's water tank is calculated. When the water output of the water supply truck is equal to the amount of water added to the aircraft's water tank, a second command is sent to the booster pump to shut down the booster pump and end the water adding process. This achieves intelligent control of the aircraft's water tank adding process, reduces human judgment errors, ensures the accuracy of the added water volume, provides sufficient water for cabin service, minimizes the remaining water volume, and saves fuel and water costs.

[0051] In one optional embodiment, the formula for calculating the target water consumption is:

[0052] W total =T*N people *X+Y

[0053] Among them, W totalThe target water consumption for the flight to take off is represented by N; T represents the flight time of the flight to take off; people X represents the number of passengers on the flight to be launched; Y represents the flight coefficient of the aircraft type; and Y represents the reserved safety value of the water tank capacity of the aircraft type.

[0054] In this embodiment of the invention, multiple factors such as flight time, number of passengers, flight coefficient of aircraft type, and reserved safety value of water tank capacity are considered to ensure the accuracy of the target water consumption and to provide sufficient water resources for the aircraft to meet the needs of passengers and crew.

[0055] In one optional embodiment, the flight coefficient is obtained through the following steps:

[0056] Obtain historical flight coefficient data for the most recent 30 completed flights;

[0057] The flight coefficient of the current flight is obtained by taking a weighted average of the historical flight coefficient data.

[0058] If the number of historical flights of a flight is less than thirty, the missing historical flight coefficient data will be replaced by the initial value of the flight coefficient.

[0059] It is understood that the flight coefficient of the aircraft is used to describe the average water consumption per person during the flight, and the unit is liters / person / hour. The flight coefficient of the aircraft ranges from 0.1 to 0.6, and the flight coefficient varies depending on the aircraft type. For example: the flight coefficient of the ARJ aircraft type is 0.14; the flight coefficient of the A320 aircraft type is 0.16; the flight coefficient of the A738 aircraft type is 0.18; the flight coefficient of the A330 aircraft type is 0.4; the flight coefficient of the A350 aircraft type is 0.5; the flight coefficient of the A787 aircraft type is 0.45; and the flight coefficient of the A777 aircraft type is 0.6.

[0060] In this embodiment of the invention, by considering recent historical flight data, a weighted average method is used to calculate the flight coefficient of the currently waiting flight, giving newer data a greater weight and more accurately estimating the per capita water consumption of the flight. Simultaneously, to address situations where the number of historical flights is insufficient, the initial value of the flight coefficient is used for appropriate supplementation to ensure a relatively reasonable flight coefficient is obtained.

[0061] In one optional embodiment, the formula for calculating the reserved safety value is:

[0062]

[0063] Where Y represents the reserved safety value of the water tank capacity of the aircraft model; Y0 represents the initial reserved safety value of the water tank capacity of the aircraft model; N people N represents the number of passengers on the flight to be launched. seat q represents the number of seats on the aircraft for the flight to be launched; q represents the step coefficient.

[0064] Understandably, with the same passenger capacity, a longer flight time results in a higher safety margin, but this increase is not linear. According to current regulations, in-flight services are suspended within 20 minutes of takeoff and 30 minutes before landing because flights with a flight time of less than one hour consume almost no water. Historical data shows that passenger activity and water consumption are higher in the 0.5 to 3 hours after takeoff. As flight time increases, most passengers choose to rest, resulting in lower activity and water consumption.

[0065] The initial safety reserve value for the aircraft's water tank capacity ranges from 5% to 15% of the tank capacity. The initial safety reserve value varies depending on the aircraft model. For example, the initial safety reserve value for the ARJ model is 5% of the water tank capacity; for the A320, 738, 330, and 350 models, it is 10%; for the 787 model, it is 12%; and for the 777 model, it is 15%.

[0066] In this embodiment of the invention, even with the same passenger capacity, the reserved safety value of the aircraft water tank capacity does not increase linearly with the increase of flight time. Instead, it takes into account multiple factors, including the number of passengers, number of seats, differences in aircraft type, and flight time, to dynamically calculate and adjust the reserved safety value of the aircraft water tank capacity, so as to ensure sufficient water supply under different flight scenarios without wasting water resources.

[0067] In one optional embodiment, the step coefficient is determined based on the flight time of the flight to be launched, and the value of the step coefficient increases as the flight time of the flight to be launched increases; wherein, when the flight time of the flight to be launched is greater than a preset flight time, the step coefficient is taken at its maximum value.

[0068] It is understood that when the flight time of the waiting flight is less than or equal to 1 hour, the step coefficient takes the minimum value of 0.1; when the flight time of the waiting flight is greater than 1 hour and less than or equal to 2 hours, the step coefficient takes the value of 0.2; when the flight time of the waiting flight is greater than 2 hours and less than or equal to 3 hours, the step coefficient takes the value of 0.3; when the flight time of the waiting flight is greater than 3 hours and less than or equal to 4 hours, the step coefficient takes the value of 0.4; when the flight time of the waiting flight is greater than 4 hours and less than or equal to 5 hours, the step coefficient takes the value of 0.5; when the flight time of the waiting flight is greater than 5 hours... When the flight time is less than or equal to 6 hours, the step coefficient is 0.6; when the flight time of the waiting flight is greater than 6 hours and less than or equal to 7 hours, the step coefficient is 0.7; when the flight time of the waiting flight is greater than 7 hours and less than or equal to 8 hours, the step coefficient is 0.75; when the flight time of the waiting flight is greater than 8 hours and less than or equal to 9 hours, the step coefficient is 0.8; when the flight time of the waiting flight is greater than 9 hours and less than or equal to 10 hours, the step coefficient is 0.9; when the flight time of the waiting flight is greater than 10 hours, the step coefficient takes the maximum value of 1.0.

[0069] In this embodiment of the invention, the step coefficient affects the adjustment of the water tank capacity reserve safety value. Due to varying passenger water demand during different flight periods, the step coefficient increases with the flight time of the waiting flight, but not in a linear proportion. This value effectively optimizes water reserve, making it more aligned with actual needs. When the flight time of the waiting flight is long, the step coefficient will be adjusted to its maximum, increasing the aircraft water tank capacity reserve safety value to ensure sufficient water supply.

[0070] In one optional embodiment, the formula for calculating the flow error compensation value is:

[0071] Z = L * ΔT

[0072] Where Z represents the flow error compensation value; L represents the flow rate when the water supply truck discharges water; and ΔT represents the time interval for the flow meter to collect signals.

[0073] Under normal circumstances, the flow rate of a water supply truck is around 3.0 L / s. However, because the pressure of the booster pump in the water supply truck fluctuates, a fixed value cannot be set. Currently, the time interval for the flow meter to collect signals is between 0.5 seconds and 1 second, which can be set manually.

[0074] In this embodiment of the invention, due to the high flow rate of water discharged from the water supply truck and the time interval in the flow meter's signal acquisition, there is an error between the actual water discharge from the water supply truck and the amount of water required to fill the aircraft's water tank. Therefore, the average flow rate of the first 10 seconds of water discharge is collected to obtain the actual water flow rate. This value is then multiplied by the flow meter's sampling interval to obtain a flow error compensation value. This avoids subsequent calculation errors in the actual water filling amount for the aircraft's water tank, improves the accuracy of water filling calculation, and reduces water waste.

[0075] In one optional embodiment, the formula for calculating the amount of water added is:

[0076] W add =W total -W remain -Z

[0077] Among them, W add This indicates the amount of water added to the aircraft's water tank; W total This indicates the target water consumption for the flight to be launched; W remain Z represents the remaining water volume in the aircraft's water tank; Z represents the flow error compensation value.

[0078] In this embodiment of the invention, the amount of water to be added to the aircraft water tank is calculated by using the target water consumption of the flight to be launched, the remaining water volume in the aircraft water tank, and the flow error compensation value when the water supply truck actually dispenses water. This improves the accuracy of the water addition calculation, reduces water waste, and saves fuel and water costs.

[0079] The method for intelligently controlling aircraft water replenishment provided in this invention first acquires the flight information of the flight to be launched and the remaining water volume in the aircraft's water tank; the flight information includes the flight time, number of passengers, and aircraft type; then, based on the flight information, the target water consumption of the flight to be launched is calculated; when the remaining water volume is lower than the target water consumption, a first command is sent to the booster pump of the water supply truck to start the booster pump to replenish the aircraft's water tank; then, the actual flow rate of the water supply truck is acquired, and a flow error compensation value is calculated based on the actual flow rate and a preset flow meter signal acquisition time interval; next, the amount of water added to the aircraft's water tank is calculated based on the remaining water volume in the aircraft's water tank, the target water consumption, and the flow error compensation value; when the water volume from the water supply truck is equal to the amount of water added to the aircraft's water tank, a second command is sent to the booster pump to shut off the booster pump and end the water replenishment process. Therefore, the embodiments of the present invention can realize intelligent control of the water filling process of aircraft water tanks, reduce human judgment errors, ensure the accuracy of water filling, provide sufficient water for cabin service, and minimize the amount of water left over, thereby saving fuel and water costs.

[0080] See Figure 2 , Figure 2This is a structural block diagram of a system 10 for intelligent control of aircraft water replenishment provided in an embodiment of the present invention. The system 10 for intelligent control of aircraft water replenishment includes:

[0081] The data acquisition module is used to acquire the flight information of the flight to be launched and the remaining water level in the aircraft's water tank; the flight information includes the flight time, number of passengers and aircraft type.

[0082] The target water consumption calculation module is used to calculate the target water consumption of the flight to be launched based on the flight information.

[0083] The water filling module is activated to send a first command to the booster pump of the water supply truck when the remaining water volume is lower than the target water consumption, so as to start the booster pump to add water to the aircraft water tank;

[0084] The water volume calculation module is used to obtain the actual flow rate when the water supply truck discharges water, calculate the flow error compensation value based on the actual flow rate and the preset flow meter signal acquisition time interval, and calculate the water volume added to the aircraft water tank based on the remaining water volume in the aircraft water tank, the target water volume, and the flow error compensation value.

[0085] The water filling module is used to send a second command to the booster pump to shut down the booster pump and end the water filling process when the water output of the water supply truck is equal to the water filling of the aircraft water tank.

[0086] Optionally, the formula for calculating the target water consumption is:

[0087] W total =T*N people *X+Y

[0088] Among them, W total The target water consumption for the flight to take off is represented by N; T represents the flight time of the flight to take off; people X represents the number of passengers on the flight to be launched; Y represents the flight coefficient of the aircraft type; and Y represents the reserved safety value of the water tank capacity of the aircraft type.

[0089] Optionally, the flight coefficient can be obtained through the following steps:

[0090] Obtain historical flight coefficient data for the most recent 30 completed flights;

[0091] The flight coefficient of the current flight is obtained by taking a weighted average of the historical flight coefficient data.

[0092] If the number of historical flights of a flight is less than thirty, the missing historical flight coefficient data will be replaced by the initial value of the flight coefficient.

[0093] Optionally, the formula for calculating the reserved safety value is:

[0094]

[0095] Where Y represents the reserved safety value of the water tank capacity of the aircraft model; Y0 represents the initial reserved safety value of the water tank capacity of the aircraft model; N people N represents the number of passengers on the flight to be launched. seat q represents the number of seats on the aircraft for the flight to be launched; q represents the step coefficient.

[0096] Optionally, the step coefficient is determined based on the flight time of the flight to be flown, and the value of the step coefficient increases as the flight time of the flight to be flown increases; wherein, when the flight time of the flight to be flown is greater than the preset flight time, the step coefficient is taken at its maximum value.

[0097] Optionally, the formula for calculating the flow error compensation value is:

[0098] Z = L * ΔT

[0099] Where Z represents the flow error compensation value; L represents the flow rate when the water supply truck discharges water; and ΔT represents the time interval for the flow meter to collect signals.

[0100] Optionally, the formula for calculating the amount of water added is:

[0101] W add =W total -W remain -Z

[0102] Among them, W add This indicates the amount of water added to the aircraft's water tank; W total This indicates the target water consumption for the flight to be launched; W remain Z represents the remaining water volume in the aircraft's water tank; Z represents the flow error compensation value.

[0103] It is worth noting that the working process of each module in the system 10 for intelligent control of aircraft water filling described in the embodiments of the present invention can refer to the working process of the method for intelligent control of aircraft water filling described in the above embodiments, and will not be repeated here.

[0104] For example, the system 10 for intelligent control of aircraft water replenishment can consist of a cloud platform management system, a handheld terminal, and an intelligent water replenishment control unit. The cloud platform management system receives flight information for a waiting flight and the remaining water volume in the aircraft's water tank, and calculates the target water consumption for the flight. When the remaining water volume is lower than the target water consumption, the handheld terminal, through an aircraft water replenishment app, selects the flight number and pushes the target water consumption calculated by the cloud platform to the intelligent water replenishment control unit. Based on the target water consumption data from the cloud platform management system, the intelligent water replenishment control unit sends a command to start the water pump in the water supply truck to replenish the aircraft's water tank. It obtains the actual flow rate of the water supply truck, uploads it to the cloud platform to calculate the flow rate error compensation value and the water replenishment volume in the aircraft's water tank, and pushes the water replenishment volume in the aircraft's water tank to the intelligent water replenishment control unit. When the intelligent water replenishment control unit detects that the actual water output from the water supply truck is equal to the water replenishment volume data sent by the cloud platform management system, it sends a command to shut off the water pump, ending the water replenishment task. Simultaneously, information such as flight number, aircraft number, water volume, water supply truck, and operator is automatically uploaded to the cloud platform management system. The intelligent water supply control unit, for example... Figure 3 As shown.

[0105] The system for intelligently controlling aircraft water replenishment provided in this embodiment of the invention first acquires the flight information of the flight to be launched and the remaining water volume in the aircraft's water tank; the flight information includes the flight time, number of passengers, and aircraft type; then, based on the flight information, the target water consumption of the flight to be launched is calculated; when the remaining water volume is lower than the target water consumption, a first command is sent to the booster pump of the water supply truck to start the booster pump to replenish the aircraft's water tank; then, the actual flow rate of the water supply truck is acquired, and a flow error compensation value is calculated based on the actual flow rate and a preset flow meter signal acquisition time interval; next, the amount of water added to the aircraft's water tank is calculated based on the remaining water volume in the aircraft's water tank, the target water consumption, and the flow error compensation value; when the water volume from the water supply truck is equal to the amount of water added to the aircraft's water tank, a second command is sent to the booster pump to shut off the booster pump and end the water replenishment process. Therefore, the embodiments of the present invention can realize intelligent control of the water filling process of aircraft water tanks, reduce human judgment errors, ensure the accuracy of water filling, provide sufficient water for cabin service, and minimize the amount of water left over, thereby saving fuel and water costs.
