Description

Technical Field

[0001] This invention relates to the field of aviation technology, and in particular to a simulation method, apparatus, electronic device, and storage medium for aircraft fuel service. Background Technology

[0002] In the aviation field, the aircraft fuel service system is a crucial link in ensuring flight safety and operational efficiency. Its operational standardization and maintenance professionalism directly impact the safety of fuel refueling, transfer, and use. With the rapid development of aviation technology, new aircraft place higher demands on the precision requirements of fuel service (such as multi-tank collaborative management and compatibility with special fuels) and the skill levels of personnel. There is an urgent need to improve the operational proficiency and emergency response capabilities of service personnel through efficient and low-cost simulation training methods. Simultaneously, to reduce the cost risks of actual fuel system research and development and testing, the need for in-depth research on the functional optimization and internal working mechanisms of the fuel service system is increasingly urgent. This includes both functional verification of the overall system and refined analysis of distributed components (such as fuel tank control modules and sensor networks) to support a safer and more reliable fuel system design and personnel training system.

[0003] Existing simulations of aircraft fuel service systems mostly focus on the development of auxiliary tools for functional optimization and generally concentrate on the overall verification of the "test assembly," failing to conduct detailed simulation studies on the components of the aircraft fuel service system. Summary of the Invention

[0004] This invention provides a simulation method, apparatus, electronic device, and storage medium for aircraft fuel service, which addresses the shortcomings of existing aircraft fuel service simulations that cannot perform detailed simulation studies on components, and enables detailed simulation studies of the components of the aircraft fuel service system.

[0005] This invention provides a simulation method for aircraft fuel service, comprising: Based on the refueling type and tank number of the aircraft fuel, simulate the refueling signal of at least one tank; the refueling types include gravity refueling and pressure refueling. The amount of fuel already added to each tank is calculated based on each refueling signal and its duration, and the refueling process of each tank is simulated based on the amount of fuel already added.

[0006] The simulation method for aircraft fuel service provided by the present invention simulates the refueling process of each fuel tank based on the amount of fuel already refueled, including: The fuel storage capacity of each tank is determined based on the original fuel quantity of each tank and the sum of the fuel already added. For each fuel level, when the fuel level is less than the tank capacity, the duration of the refueling signal is increased. For each fuel level, based on the duration of the increased refueling signal, the amount of fuel already refueled is updated to update the fuel level until the updated fuel level equals the tank capacity, thus simulating the generation of a stop refueling signal for the tank.

[0007] According to the simulation method for aircraft fuel service provided by the present invention, based on the refueling type and tank number, the method simulates a refueling signal for at least one tank, including: When the refueling type is gravity refueling, the simulated electrical signal is identified based on at least one number to obtain at least one refueling signal; When the refueling type is pressure refueling and a pressure refueling start command is obtained; the simulated electrical signal is identified based on at least one number and the pressure refueling start command to obtain at least one refueling signal.

[0008] According to the simulation method for aircraft fuel service provided by the present invention, the refueling type and number are generated after receiving user input instructions from the aircraft's refueling control panel. Before simulating the refueling signal of at least one fuel tank based on the aircraft fuel refueling type and fuel tank number, the method further includes: When a self-test signal is received from the refueling control panel and the preset self-test completion time has not been exceeded, the status information of each fuel tank is displayed based on the reception of fault signals from each fuel tank to simulate the self-test process of the refueling control panel. After the refueling control panel passes the self-test, the steps of simulating the refueling signal of at least one fuel tank based on the refueling type and fuel tank number are executed.

[0009] The simulation method for aircraft fuel service provided by the present invention, after simulating the refueling process of each fuel tank based on each refueling amount, further includes: When a fuel transfer command is received from the target fuel tank, a fuel transfer signal is simulated and generated. Based on the fuel transfer signal and its duration, the remaining fuel quantity and the amount of fuel transferred out of the target fuel tank are calculated to simulate the fuel transfer process of the target fuel tank. When the remaining fuel quantity is greater than the set minimum capacity, the duration of the fuel dispensing signal is increased. Based on the fuel dispensing signal and the increased duration of the fuel dispensing signal, the remaining fuel quantity and the amount of fuel dispensing are updated until the updated remaining fuel quantity equals the set minimum capacity. Then, the simulation of fuel dispensing stops, and the last updated remaining fuel quantity and the last updated amount of fuel dispensing are output.

[0010] According to the simulation method for aircraft fuel service provided by the present invention, the fuel transfer command is received in the following manner: When the first switch signal from the aircraft's fuel panel and the second switch signal from the refueling control panel are received, the aircraft's cross-flow valve opening signal is simulated and generated. The cross-flow valve is used to connect the two fuel tanks for fuel transfer. Based on the opening signal of the fuel pump to be transferred and the opening signal of the transfer valve, a fuel transfer command is simulated and generated.

[0011] According to the simulation method for aircraft fuel service provided by the present invention, the amount of fuel refueled in each fuel tank is calculated based on each refueling signal and the duration of each refueling signal, including: Based on the strength of each refueling signal, determine each refueling rate; By integrating the refueling rates over the duration of the refueling signal, the amount of fuel already refueled in each tank can be obtained.

[0012] The present invention also provides a simulation device for aircraft fuel service, comprising: The generation module is used to simulate a refueling signal for at least one fuel tank based on the refueling type and tank number of the aircraft fuel; the refueling types include gravity refueling and pressure refueling. The simulation module is used to calculate the amount of fuel already added to each fuel tank based on each refueling signal and the duration of each refueling signal, and to simulate the refueling process of each fuel tank based on the amount of fuel already added.

[0013] The present invention also provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement any of the above-described aircraft fuel service simulation methods.

[0014] The present invention also provides a non-transitory computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements a simulation method for aircraft fuel service as described above.

[0015] This invention provides a simulation method, apparatus, electronic device, and storage medium for aircraft fuel service. Based on the refueling type and tank number, it simulates refueling signals for at least one tank. Refueling types include gravity refueling and pressure refueling. The method calculates the amount of fuel already refueled for each tank based on each refueling signal and its duration, and simulates the refueling process for each tank based on the refueled amount. This invention simulates various refueling signals for different aircraft types and tanks through refueling type and tank numbering, enabling distributed simulation of the refueling process for each tank in the aircraft fuel service system. By calculating the amount of fuel already refueled based on the refueling signal and its duration, it achieves a refined simulation of the refueling process. The aircraft fuel service simulation method of this invention can simulate receiving operation signals from the refueling control panel and, by calculating and outputting the refueled amount and refueling signals for tanks with different numbers, can simulate the refueling process and operations of real ground service personnel, providing a virtualized solution for training, testing, or optimizing fuel service processes.

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0025] The following is combined with Figures 1-7 The present invention describes a simulation method, apparatus, and electronic equipment for aircraft fuel service.

[0026] Figure 1 This is one of the flowcharts illustrating the simulation method for aircraft fuel service provided by this invention, such as... Figure 1 As shown, the simulation method for aircraft fuel service includes steps S100 to S200, and the specific steps are as follows.

[0027] S100: Based on the refueling type and tank number, simulates the refueling signal of at least one tank; refueling types include gravity refueling and pressure refueling.

[0028] Gravity refueling utilizes the weight of the fuel itself to draw fuel into the tank. This is achieved by opening or partially opening the refueling port on the upper surface of the wing or the upper part of the fuselage to inject fuel into the tank.

[0029] Pressure refueling is a method of adding fuel to an aircraft's fuel tanks in a closed system under specified pressure using ground-based pressure refueling equipment (e.g., tanker trucks or pipeline refueling systems) via a refueling manifold and control accessories. Pressure refueling is characterized by its rapid refueling, high degree of automation, and the ability to refuel while the aircraft engines are running.

[0030] Aircraft have multiple fuel tanks. To ensure the aircraft's left and right weight balance, the fuel tanks are usually evenly distributed on both sides of the wings, and the weight of fuel in the tanks on both sides is the same. The aircraft's fuel tanks are numbered, for example, tank 1, tank 2, tank 3, and tank 4. Each tank corresponds to a specific fuel capacity. The amount of fuel stored in a tank cannot exceed its capacity.

[0031] The system acquires pre-set information regarding the aircraft fuel refueling type, tank number, and tank capacity. Based on the different refueling types and tank numbers, it simulates refueling signals for each tank. Each tank refueling signal carries the refueling type and tank number. For example, tank refueling signals might include gravity refueling for tank 1, pressure refueling for tank 1, gravity refueling for tank 2, and pressure refueling for tank 2.

[0032] Furthermore, this invention can simultaneously simulate refueling signals from multiple fuel tanks, as well as refueling signals from different types of refueling within the same fuel tank. For example, it can simultaneously simulate gravity refueling from fuel tank 1 and fuel tank 2. Alternatively, it can simultaneously simulate gravity refueling from fuel tank 1 and pressure refueling from fuel tank 1.

[0033] S200: Calculates the amount of fuel already added to each tank based on each refueling signal and its duration, and simulates the refueling process of each tank based on the amount of fuel already added.

[0034] The refueling signal is used to simulate the action of refueling an aircraft's fuel tanks. The duration of the refueling signal simulates the time it takes to refuel the aircraft's fuel tanks. By using the refueling signal and its duration, the refueling process of an aircraft's fuel tanks can be simulated.

[0035] For example, the refueling signal is gravity refueling of fuel tank 1. The duration of the refueling signal is 5 minutes. Based on the refueling signal and its duration, a 5-minute gravity refueling process can be simulated for fuel tank 1.

[0036] Furthermore, the refueling rate is simulated by the strength of the refueling signal. For example, a stronger refueling signal results in a faster refueling rate, while a weaker signal results in a slower refueling rate.

[0037] Optionally, during the initial refueling phase (e.g., the first 3 minutes of refueling), the intensity of the refueling signal gradually increases to a stable value to simulate the gradual increase in refueling rate to a stable value. During the middle refueling phase (e.g., 3-12 minutes after refueling begins), the intensity of the refueling signal remains stable to simulate a constant refueling rate. During the final refueling phase (e.g., the last 3 minutes of refueling), the intensity of the refueling signal gradually decreases until it reaches zero to simulate the gradual decrease in refueling rate to zero.

[0038] This invention provides a simulation method for aircraft fuel service, which simulates refueling signals for at least one fuel tank based on the refueling type and tank number. Refueling types include gravity refueling and pressure refueling. The method calculates the amount of fuel already refueled for each tank based on each refueling signal and its duration, and then simulates the refueling process for each tank based on the refueled amount. This invention simulates various refueling signals for different aircraft types and tanks through refueling type and tank numbering, enabling distributed simulation of the refueling process for each tank in the aircraft fuel service system. By calculating the amount of fuel already refueled based on the refueling signal and its duration, it achieves a refined simulation of the refueling process. This aircraft fuel service simulation method can simulate receiving operation signals from the refueling control panel and, by calculating and outputting the refueled amount and refueling signals for tanks with different numbers, can simulate the refueling process and operations of real ground service personnel, providing a virtualized solution for training, testing, or optimizing fuel service processes.

[0039] Based on the above embodiments, based on the refueling type of aircraft fuel and the fuel tank number, simulating a refueling signal for at least one fuel tank includes: When the refueling type is gravity refueling, the simulated electrical signal is identified based on at least one number to obtain at least one refueling signal; When the refueling type is pressure refueling and a pressure refueling start command is obtained; the simulated electrical signal is identified based on at least one number and the pressure refueling start command to obtain at least one refueling signal.

[0040] Analog electrical signals include encoded electrical signals. There are many types of analog electrical signals. For example... Figure 3 As shown, when the refueling type is gravity refueling, the simulated electrical signals are identified according to their numbers to obtain the refueling signal. For example, the simulated electrical signals include signals A, B, C, and D. The numbers include fuel tank 1, fuel tank 2, fuel tank 3, and fuel tank 4. Signal A is identified as gravity refueling for fuel tank 1, resulting in the refueling signal. Signal B is identified as gravity refueling for fuel tank 2, resulting in the refueling signal. Signal C is identified as gravity refueling for fuel tank 3, resulting in the refueling signal. Signal D is identified as gravity refueling for fuel tank 4, resulting in the refueling signal.

[0041] The initiation command for pressure refueling is generated by the aircraft's refueling control panel. For example, clicking the pressure refueling button on the control panel generates the initiation command. Gravity refueling does not require an initiation command; it can be performed simply by opening the refueling port on the upper surface of the wing or fuselage. Pressure refueling, however, requires the activation of ground-based pressure refueling equipment and the aircraft's own control accessories. The pressure refueling initiation command instructs the activation of ground-based pressure refueling equipment and the aircraft's own control accessories to prepare for pressure refueling.

[0042] like Figure 4 As shown, when the refueling type is pressure refueling, a pressure refueling start command is obtained. Based on the number and the pressure refueling start command, the simulated electrical signals are identified to obtain a refueling signal. For example, the types of simulated electrical signals also include E, F, G, and H signals. The E signal is identified as pressure refueling for tank 1. The F signal is identified as pressure refueling for tank 2, resulting in a refueling signal. The G signal is identified as pressure refueling for tank 3, resulting in a refueling signal. The H signal is identified as pressure refueling for tank 4, resulting in a refueling signal. When a pressure refueling start command is received from the refueling control panel, the simulated electrical signals are identified according to at least one number and the pressure refueling start command to obtain at least one refueling signal.

[0043] This invention simulates the preparation work before pressure refueling by using the start command of pressure refueling to distinguish between pressure refueling and gravity refueling, thus achieving accurate simulation of different refueling types.

[0044] Based on the above embodiments, the refueling process of each fuel tank is simulated based on the amount of fuel already refueled, including: The fuel storage capacity of each tank is determined based on the original fuel quantity of each tank and the sum of the fuel already added. For each fuel level, when the fuel level is less than the tank capacity, the duration of the refueling signal is increased. For each fuel level, based on the duration of the increased refueling signal, the amount of fuel already refueled is updated to update the fuel level until the updated fuel level equals the tank capacity, thus simulating the generation of a stop refueling signal for the tank.

[0045] The original fuel level in the fuel tank includes the amount of fuel already stored in the tank before refueling. The fuel tank capacity includes the maximum fuel capacity of the tank.

[0046] During the simulated refueling process, the original fuel level and the amount of fuel already refueled are added together to obtain the fuel level in the tank. For example... Figure 3As shown, during the gravity refueling simulation, based on the received refueling signals, it is determined whether fuel tank 1, fuel tank 2, fuel tank 3, and fuel tank 4 are being refueled by gravity. If it is determined that only fuel tank 1 is being refueled by gravity, the amount of fuel already refueled in fuel tank 1 is calculated in real time to simulate the fuel increase process in fuel tank 1. Or, as... Figure 4 As shown, during the pressure refueling simulation, based on the received refueling signals, it is determined whether fuel tank 1, fuel tank 2, fuel tank 3, and fuel tank 4 are being refueled under pressure. If it is determined that only fuel tank 1 is being refueled under pressure, the amount of fuel already refueled in fuel tank 1 is calculated in real time to simulate the fuel increase process in fuel tank 1.

[0047] like Figure 3 and Figure 4 As shown, during both gravity refueling and pressure refueling processes, the fuel level in each tank is compared with its corresponding capacity in real time. For example, the fuel level in tank #1 is compared with its capacity. If the fuel level in a tank is less than its corresponding capacity, the refueling signal continues to be received, and the duration of the refueling signal is increased. The amount of fuel already refueled is increased based on the increased duration. The fuel level is then increased based on the increased amount of fuel already refueled. If the final increased fuel level equals the corresponding tank capacity, the refueling signal is stopped, a stop refueling signal for the tank is simulated, and the last updated fuel level is output.

[0048] Furthermore, for pressure refueling, after simulating the generation of a stop refueling signal for the fuel tank, a corresponding fuel tank refueling control valve status light signal is generated to simulate a notification that the fuel tank is full.

[0049] This invention simulates the increase in fuel volume during the refueling process by simulating the increase in duration and thus the increase in the amount of fuel already refueled.

[0050] Based on the above embodiments, the refueling type and number are generated after receiving user input commands from the aircraft's refueling control panel. Before simulating a refueling signal for at least one fuel tank based on the aircraft's fuel refueling type and tank number, the process further includes: When a self-test signal is received from the refueling control panel and the preset self-test completion time has not been exceeded, the status information of each fuel tank is displayed based on the reception of fault signals from each fuel tank to simulate the self-test process of the refueling control panel. After the refueling control panel passes the self-test, the steps of simulating the refueling signal of at least one fuel tank based on the refueling type and fuel tank number are executed.

[0051] The refueling control panel is the core operating interface used to monitor, control, and manage the entire aircraft refueling process. It serves as the refueling command center for the aircraft's fuel system, displaying information such as the tank numbers to be refueled, the tank numbers to be transferred, the fuel quantity, and the refueling type. The refueling control panel includes physical devices integrating various switches, buttons, indicator lights, and displays. Users specify the tank numbers to be refueled, the tank numbers to be transferred, the fuel quantity, and the refueling type by operating the buttons on the overhead control panel.

[0052] The fuel tank's status information includes the fuel level and whether a malfunction exists. For example, if a malfunction occurs, the fuel level indicator will display a fault code, and the malfunction indicator light will illuminate red. If there is no malfunction, the malfunction indicator light will illuminate yellow.

[0053] like Figure 2 As shown, the fault signal of the fuel tank can be simulated as needed. For example, to simulate a fault in fuel tank #1, a fault signal for fuel tank #1 can be generated. The reception status of the fuel tank fault signal includes whether the fault signal is received or not.

[0054] Before simulating the refueling signal from the fuel tank, it is also necessary to simulate the self-test process of the refueling control panel. Set the preset completion time for the self-test and determine whether to inject a fault signal from the fuel tank.

[0055] like Figure 2 As shown, when a self-test signal is received from the refueling control panel, the self-test of the refueling control panel is initiated. During the self-test, the status information of the fuel tanks is displayed based on the received fault signals. For example, if no fault signals are received from any fuel tanks and the preset self-test completion time has not exceeded, the fuel level indicator area dynamically loads the fuel level values ​​of each fuel tank, and the fault indicator lights of each fuel tank are displayed in yellow sequentially.

[0056] During the self-test, if a fault signal is received from a fuel tank, the system will display the fuel tank's status information based on the signal. For example, if a fault signal is received from fuel tank #1, the system will display the fuel level in fuel tank #1, and the indicator light for fuel tank #1 will turn red.

[0057] During the self-test, if the self-test time reaches the preset completion time, the self-test will end.

[0058] The refueling control panel's self-test is complete, displaying various status information for each fuel tank. For example, the fuel level in tank 1 is displayed correctly; when a fault signal is received from tank 1, its indicator light illuminates yellow; when no fault signal is received from tank 1, its indicator light illuminates red.

[0059] After the refueling control panel passes the self-test, it will execute a step based on the refueling type and tank number of the aircraft fuel, simulating the refueling signal of at least one tank, in order to proceed with the subsequent gravity refueling or pressure refueling steps.

[0060] This invention displays the status information of each fuel tank by receiving fault signals from each tank, enabling self-testing of the function buttons and indicator lights of each fuel tank on the refueling control panel, thus simplifying the self-testing process. Furthermore, by displaying the status information of each fuel tank based on the received fault signals, it can simulate almost all fuel tank fault conditions, improving the self-testing efficiency of the refueling control panel.

[0061] Based on the above embodiments, after simulating the refueling process of each fuel tank based on the amount of fuel already refueled, the method further includes: When a fuel transfer command is received from the target fuel tank, a fuel transfer signal is simulated and generated. Based on the fuel transfer signal and its duration, the remaining fuel quantity and the amount of fuel transferred out of the target fuel tank are calculated to simulate the fuel transfer process of the target fuel tank. When the remaining fuel quantity is greater than the set minimum capacity, the duration of the fuel dispensing signal is increased. Based on the fuel dispensing signal and the increased duration of the fuel dispensing signal, the remaining fuel quantity and the amount of fuel dispensing are updated until the updated remaining fuel quantity equals the set minimum capacity. Then, the simulation of fuel dispensing stops, and the last updated remaining fuel quantity and the last updated amount of fuel dispensing are output.

[0062] The fuel transfer command is used to instruct the initiation of fuel transfer. The target fuel tank includes the tank containing the fuel to be transferred. Upon receiving the fuel transfer command from the target fuel tank, a simulated fuel transfer signal is generated. The fuel transfer signal is used to instruct the transfer of fuel to the target fuel tank. To ensure weight balance on both sides of the wing, it is sometimes necessary to transfer fuel between the fuel tanks on both sides of the wing to balance the weight on both sides.

[0063] Furthermore, the fuel dispensing rate is simulated by the intensity of the fuel dispensing signal. For example, a stronger fuel dispensing signal indicates a higher fuel dispensing rate, while a weaker signal indicates a lower fuel dispensing rate.

[0064] like Figure 5 As shown, based on the fuel dispensing signal and its duration, the remaining fuel quantity and the amount of fuel dispensing from the target tank are calculated to simulate the fuel dispensing process of the target tank. For example, the intensity of the fuel dispensing signal is integrated based on its duration to obtain the amount of fuel dispensing. The remaining fuel quantity in the target tank is calculated based on the difference between the original fuel quantity and the amount of fuel dispensing.

[0065] The system continuously compares the remaining fuel level in the target fuel tank with its set minimum capacity. If the remaining fuel level exceeds the set minimum capacity, it continues to receive fuel dispensing signals and increases the duration of these signals. Based on the fuel dispensing signals and their increased duration, it updates the remaining fuel level and the amount of fuel dispensed until the updated remaining fuel level equals the set minimum capacity. At this point, it stops receiving fuel dispensing signals to cease simulating fuel dispensing and outputs the last updated remaining fuel level and the last updated amount of fuel dispensed.

[0066] like Figure 5 As shown, further, the fuel transfer process of each fuel tank is simulated in a distributed manner. After generating the fuel tank transfer signal, the corresponding fuel transfer signal for the fuel tank is generated, for example, the fuel transfer signal for fuel tank number 2.

[0067] Furthermore, based on the fuel transfer commands from different fuel tanks, fuel transfer signals for different fuel tanks are simulated and generated to achieve distributed simulation of the fuel transfer process for each fuel tank.

[0068] This invention updates the remaining fuel quantity and the amount of fuel transferred out by using the fuel transfer signal and the duration of the increased fuel transfer signal, thereby achieving dynamic simulation of the fuel transfer process from the fuel tank and realizing refined simulation of the aircraft fuel service system.

[0069] Based on the above embodiments, the fuel transfer command is received in the following manner: When the first switch signal from the aircraft's fuel panel and the second switch signal from the refueling control panel are received, the aircraft's cross-flow valve opening signal is simulated and generated. The cross-flow valve is used to connect the two fuel tanks for fuel transfer. Based on the opening signal of the fuel pump to be transferred and the opening signal of the transfer valve, a fuel transfer command is simulated and generated.

[0070] Aircraft fuel control panels include those in the cockpit. These panels control the opening and closing of the fuel pumps in the fuel tanks. The refueling control panel regulates the fuel transfer process, such as the transfer method and quantity. The crossover valve is a critical isolation / connection component in the aircraft fuel system, controlling the flow between the left and right fuel supply manifolds of the wings. When the crossover valve is closed, the left and right systems are independent; when open, it connects the two systems, allowing fuel to flow and be recombined between the left and right sides.

[0071] like Figure 5 As shown, when the first switch signal output from the aircraft's fuel panel and the second switch signal output from the refueling control panel are confirmed to be received, the aircraft's cross-flow valve opening signal is simulated and generated.

[0072] A fuel transfer command is generated based on the opening signal of the fuel pump to be transferred and the opening signal of the transfer valve. For example... Figure 5 As shown, upon receiving the cross-flow valve opening signal and the No. 1 standby fuel pump opening signal, a No. 1 fuel pump discharge signal is simulated and generated. Based on the No. 1 fuel pump discharge signal, a fuel discharge command for No. 1 fuel tank is simulated and generated. Further, based on the No. 1 fuel discharge command, a fuel discharge flag for No. 1 fuel tank is generated. Based on the No. 1 fuel discharge flag, fuel is instructed to be transferred into the fuel tank.

[0073] Optionally, an emergency drain pump turn-off signal is generated based on the emergency drain pump's opening signal. A fuel drain command is then simulated based on the emergency drain pump turn-off signal. For example... Figure 5 As shown, upon receiving the activation signal for Emergency Dump Pump No. 1, a switch-out signal for Emergency Dump Pump No. 1 is generated. Based on this switch-out signal, a fuel transfer command for Fuel Tank No. 1 is simulated and generated. The Emergency Dump Pump is used to drain fuel from the fuel tanks outside the aircraft.

[0074] Optionally, while generating the fuel transfer command, a simulated fuel tank refueling control valve opening signal is generated to regulate the fuel transfer into the corresponding fuel tank based on the fuel tank refueling control valve opening signal.

[0075] Optionally, while discharging fuel according to the fuel discharge command from the target fuel tank, a corresponding fuel inlet signal is simulated and generated. The amount of fuel discharged is calculated based on the fuel inlet signal from the fuel tank and then output. For example... Figure 5 As shown, a fuel transfer signal for fuel tank 2 is generated, and the fuel transfer signal for fuel tank 2 is used as a basis.

[0076] This invention simulates and generates an AC / DC valve opening signal based on a first switch signal and a second switch signal, thus realistically simulating the preconditions and details of the AC / DC valve opening.

[0077] Based on the above embodiments, the amount of fuel already dispensed in each tank is calculated based on each refueling signal and its duration, including: Based on the strength of each refueling signal, determine each refueling rate; By integrating the refueling rates over the duration of the refueling signal, the amount of fuel already refueled in each tank can be obtained.

[0078] The refueling rate is simulated by measuring the intensity of the refueling signal. A mapping relationship between the refueling signal intensity and the refueling rate is pre-established. When the actual refueling signal intensity is obtained, the refueling rate is determined based on this mapping relationship.

[0079] By integrating the refueling rates over the duration of the refueling signal, the amount of fuel already refueled in each tank can be obtained.

[0080] This invention simulates the refueling rate by measuring the intensity of the refueling signal, thus achieving a refined simulation of the aircraft refueling process. By integrating the refueling rate along the duration of the refueling signal, the amount of fuel refueled in each tank is obtained, enabling a dynamic simulation of the aircraft refueling process.

[0081] This invention utilizes distributed simulation design to meet the independent output parameter requirements of multiple modules in an aircraft fuel service system, as well as the injection of targeted special parameters, resulting in more accurate simulation results. This invention can simulate the refueling operation process for aircraft service personnel in a virtual environment, training personnel's responsiveness. It eliminates the need for physical contact with real equipment, thus removing safety hazards.

[0082] The simulation device for aircraft fuel service provided by the present invention will be described below. The simulation device for aircraft fuel service described below and the simulation method for aircraft fuel service described above can be referred to in correspondence.

[0083] like Figure 6 As shown, a simulation device for aircraft fuel service includes: The generation module is used to simulate a refueling signal for at least one fuel tank based on the refueling type and tank number of the aircraft fuel; the refueling types include gravity refueling and pressure refueling. The simulation module is used to calculate the amount of fuel already added to each fuel tank based on each refueling signal and the duration of each refueling signal, and to simulate the refueling process of each fuel tank based on the amount of fuel already added.

[0084] This invention provides a simulation device for aircraft fuel service. Based on the refueling type and tank number, it simulates refueling signals for at least one tank. Refueling types include gravity refueling and pressure refueling. Based on each refueling signal and its duration, it calculates the amount of fuel already refueled in each tank and simulates the refueling process for each tank based on the refueled amount. This invention simulates various refueling signals for different aircraft types and tanks through refueling type and tank number, enabling distributed simulation of the refueling process for each tank in the aircraft fuel service system. By calculating the amount of fuel already refueled based on the refueling signal and its duration, it achieves a refined simulation of the refueling process.
