Description

Technical Field

[0001] This invention belongs to the field of simulator platform technology, and in particular relates to a multi-freedom flight simulation control system and method for flight-assisted training. Background Technology

[0002] Flight simulation training is a flight-assisted training method used to train pilots. It typically employs hardware-in-the-loop (HIL) or hardware-in-the-loop (HIL) simulation methods, allowing pilots to undergo flight simulation training without actually entering an aircraft. This familiarizes them with aircraft operation and helps them adapt to various flight scenarios and environments. Simultaneously, the data obtained from flight simulation training is also used for the development and simulation of flight control systems and flight equipment.

[0003] Traditional flight simulation training relies on multi-degree-of-freedom motion platforms, such as those using electric drive, electro-hydraulic hybrid drive, or hydraulic drive. These platforms typically possess multi-directional movement (forward, backward, left, right, and up / down), enabling control and switching of multiple attitudes, including pitch, lateral, and sway. This is usually achieved through the coordinated propulsion of multiple hydraulic components, particularly based on a cross-linked redundant design, which is complex and typically limits the ability to perform overly complex movements. Furthermore, the lateral movement of the platform is constrained by the size of the drive components (such as hydraulic cylinders) between the upper and lower platforms, and steering is not possible. Motion control and switching are primarily regulated by actively driven hydraulic cylinders, resulting in long transition and connection times for movements. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned problems by providing a multi-freedom flight simulation control system and its control method for flight-assisted training that allows for more flexible and rapid action transitions during flight simulation.

[0005] To achieve the above objectives, a first aspect of the present invention provides a multi-freedom flight simulation control system for flight-assisted training, comprising a fixed platform, a support platform, a movable platform, and a control system.

[0007] The support platform includes multiple support columns mounted on the base;

[0008] The movable platform, located between the base and the top cover, is used to simulate flight motion. The movable platform includes a motor, a turntable, and a simulation platform.

[0009] - The simulator is located above and supported by the support column, and the simulator is equipped with a cockpit for simulating flight piloting;

[0010] - The motor is located at the upper end of the top cover, and the rotating platform is located at the lower end of the top cover. The output shaft of the motor passes through the top cover and is connected to the rotating platform to drive the rotating platform to rotate in the planar direction.

[0011] - The lower end of the top cover is provided with multiple pulley supports, and the rotating table is provided with an annular groove along its outer circumferential sidewall, which slides and engages with the pulleys of the pulley supports;

[0012] The rotating platform of the activity platform is equipped with a suspension system. The suspension system is equipped with multiple cables whose lower ends are fixed to the simulation platform and whose upper ends are connected to the hydraulic components on the rotating platform. The suspension system is configured to drive the raising and lowering of the cables by the extension and retraction of the hydraulic components, and to achieve the pitch and tilt control of the simulation platform by the lifting and lowering coordination between the multiple cables.

[0013] The control system is configured to control the operation of the motor and hydraulic components to achieve planar rotation, pitch and tilt control of the simulator.

[0014] As an optional implementation, multiple support columns are evenly arranged on the upper surface of the base to support the simulation stage from the bottom.

[0015] As an optional implementation, each support column is provided with an adaptive buffer to buffer the impact between the simulation stage and the support column supporting it.

[0016] As an optional implementation, the adaptive buffer is a spring set in the groove of the support column, with rubber sleeves covering both the outside and inside of the spring, and a retaining ball fixedly connected to the top.

[0017] The simulation platform has an annular groove at its bottom edge in the circumferential direction, and the ball engages with the annular groove and slides in connection with it.

[0018] As an optional implementation, the upper end face of the support column is provided with a first sensor for detecting the distance between the simulation stage and the support column, which is connected to the control system signal.

[0019] As an optional implementation, the rotary table includes an annular body that can be driven to rotate and a lower cavity defined by the annular body, and a disc-shaped pitch / tilt control panel integrally formed with the annular body is provided in the cavity.

[0020] As an optional implementation, the suspension system includes:

[0021] A fixing block is provided at the center of the pitch / tilt control panel, and the annular body is integrally connected to the pitch / tilt control panel through the fixing block;

[0022] Multiple sets of uniformly distributed hydraulic components are fixed to the fixed block and extend radially.

[0023] A limiting ring is provided in the radially extending direction and located at the edge of the pitch / tilt control panel;

[0024] Each limiting ring has a through hole, and each hydraulic assembly is equipped with a movable block for fixing the cable. The cable configured in each movable block passes through the through hole of the limiting ring in the corresponding radial direction and is fixedly connected to the edge of the simulation platform below.

[0025] As an optional implementation, the pitch / tilt control panel is provided with a corresponding guide groove in the radially extending direction for each movable block. Each movable block is engaged with the guide groove and is limited and guided by the guide groove.

[0026] As an optional implementation, the hydraulic components are distributed radially on the upper surface of the pitch / tilt control panel and are spaced 45 degrees apart from each other.

[0027] Each pair of hydraulic components arranged at a 90-degree angle and their corresponding cables serve as the main control components, while the hydraulic components and their corresponding cables located between the two pairs of hydraulic components arranged at a 90-degree angle serve as auxiliary control components.

[0028] As an optional implementation, each limiting ring is equipped with a second sensor inside, which is used to monitor the extension and retraction length of the cable in the corresponding radial extension direction.

[0029] The proposed multi-freedom flight simulation control system for flight-assisted training, based on the above technical solutions of the present invention, has the following significant advantages:

[0030] 1. The multi-freedom flight simulation control system proposed in this invention, through the coordination of a configured simulator, motor, hydraulic components, and cables, achieves the effect of using the motor to drive the simulator to perform horizontal turning while using the hydraulic components to control the pitch and roll movements of the simulator by retracting and extending the cables. The two work together to form the simulated flight movements. At the same time, multiple adaptive buffers at the edges further enhance the flexibility and buffering of pitch / roll movements, reduce the impact of the simulator on the platform, and make the action transitions during flight simulation more flexible and rapid, and the limit amplitude of the movements also higher.

[0031] 2. The multi-freedom flight simulation control system proposed in this invention, through the cooperation of a first sensor and a second sensor, monitors the attitude of the simulator using the first and second sensors. This facilitates the comparison between the actual movement of the simulator and the expected movement command, thereby enabling precise correction and adjustment, making the flight simulation movements more accurate.

Detailed Implementation

[0041] To better understand the technical content of the present invention, specific embodiments are described below in conjunction with the accompanying drawings.

[0042] Various aspects of the invention are described in this disclosure with reference to the accompanying drawings, which illustrate numerous illustrative embodiments. The embodiments of this disclosure are not necessarily intended to encompass all aspects of the invention. It should be understood that the various concepts and embodiments described above, as well as those described in more detail below, can be implemented in any of many ways, because the concepts and embodiments disclosed herein are not limited to any particular implementation. Furthermore, some aspects of the invention disclosed may be used alone or in any suitable combination with other aspects of the invention disclosed.

[0043] Example 1

[0044] In view of the defects or deficiencies of the prior art, and in conjunction with the embodiments of the present invention, such as Figure 1-3 As shown, a fast-response, multi-free flight simulation motion platform driven by a combination of motors and a suspension system is proposed. The main components include a fixed platform, a support platform, a movable platform, and a control system. The fixed platform serves as a base support, and both the support platform and the movable platform are housed within the fixed platform.

[0045] Fixed platform

[0046] The fixed platform includes a base 4 and a top cover 5. For example... Figure 1 , 2 The base 4 is located at the bottom, and the top cover 5 is located at the top. The base 4 can be installed on the ground with bolts or other fixing equipment and kept level.

[0047] Multiple outwardly flared arched reinforcing members 6 are provided between the base 4 and the top cover 5. Since large-scale maneuvers are required during flight simulation, in this embodiment of the invention, the reinforcing members 6 are outwardly flared arched, which allows for a larger space between the base 4 and the top cover 5, facilitating a wider range of motion simulations and preventing accidental contact. At the same time, the reinforcing members 6 are not provided on the front (as shown in the figure) to facilitate the entry and exit of flight trainees from the simulation platform.

[0048] In optional embodiments, the base 4, top cover 5, and reinforcing member 6 are typically made of hard high-strength steel, and the outwardly expanding arched structure of the reinforcing member 6 adopts a symmetrical design.

[0049] In an embodiment of the present invention, the base 4 provides basic support, resistance and load for the entire motion simulation platform, so that the active platform can maintain a relatively stable state in the initial or final state, and also helps flight trainees to safely get on and off the simulation platform.

[0050] The placement of base 4 not only allows the activity platform to stably upload and download users, but also does not excessively affect the activity platform's range of motion.

[0051] Event Platform

[0052] An active platform, located between a base 4 and a top cover 5, is used for simulating flight motion. The platform includes a motor 8, a turntable 9, and a simulator 10. The simulator 10 is located above and supported by the support column 7, and includes a cockpit 12 for simulating flight piloting.

[0053] It should be understood that the cockpit 12 is equipped with flight simulation operation components as used in existing designs, including but not limited to the control components (main joystick, steering wheel, yaw pedal and throttle console) used for flight simulation training, force feedback components, alarm components, control panel components, instrument panel, seat, seat belt, etc. The cockpit 12 is used to accommodate users who conduct flight simulation training operations, and transmits control commands through the control components to control the pitch, roll, and rotation of the flight simulation platform.

[0054] Combination Figure 3 , 4 As shown in Figure 5, the motor 8 is located at the upper end of the top cover 5, and the rotating platform 9 is located at the lower end of the top cover 5. The output shaft of the motor 8 passes through the top cover 5 and is connected to the rotating platform 9, which is used to drive the rotating platform 9 to rotate in the planar direction.

[0055] The lower end of the top cover 5 is provided with multiple pulley supports 13, and the rotating platform 9 has an annular groove 14 along its outer circumferential sidewall, which slides and engages with the pulleys of the pulley supports 13. Thus, driven by the rotation output of the motor 8, the rotating platform 9 can be supported by the pulley supports 13 and move along the annular horizontal track defined by the pulley-annular groove 14, maintaining stable horizontal rotation when the rotating platform 9 moves.

[0056] Support Platform

[0057] like Figure 1-3 In the example shown, the support platform includes multiple support columns 7 mounted on a base 4. These multiple support columns 7, with identical structural designs, are evenly distributed on the end face of the base 4 to support the simulator platform with a cockpit 12 mounted on it from the bottom.

[0058] In an optional embodiment, an adaptive buffer is provided above each support column 7 to buffer the impact between the simulation stage 10 and the support column 7 supporting it, thereby reducing and eliminating the impact when the two come into contact, and achieving a stable buffering effect.

[0059] As an optional embodiment, the adaptive buffer can be designed with a cylinder, hydraulic cylinder or the like that that can adaptively lift and lower, and a rubber pad is provided at the end of the telescopic piston rod so that the simulation platform 10 above can buffer the pressure when it falls and contacts the support column 7.

[0060] In another embodiment, combined with Figure 3 , 4 As shown, the adaptive buffer is a spring 15 disposed in the groove of the support column 7. The spring 15 is fitted with rubber sleeves on both the outside and inside, and a retaining ball 16 is fixedly connected to the top. Correspondingly, the bottom edge of the simulation stage 10 in the circumferential direction is provided with an annular groove 17, and the retaining ball 16 engages with the annular groove 17 and is slidably connected to it.

[0061] Suspension system

[0062] Combination Figure 1 , 2 As shown in Figure 3, the rotating platform 9 of the activity platform 3 is equipped with a suspension system 11. The suspension system 11 is provided with multiple cables 23 whose lower ends are fixed to the simulation platform 10 and whose upper ends are connected to the rotating platform 9. The suspension system 11 is configured to drive the cables 23 to rise and fall by extending and retracting the hydraulic components 20, and to achieve pitch and tilt control of the simulation platform 10 by the lifting and lowering coordination between the multiple cables 23.

[0063] The control system can be implemented using an embedded control system, and is configured to control the operation of the motor 8 and the hydraulic components 20 to achieve planar rotation, pitch and tilt control of the simulation platform 10.

[0064] Combination Figure 1 , 2 As shown in Figures 3 and 5, the rotating platform 9 includes an annular body 9A that can be driven to rotate and a lower cavity defined by the annular body 9A. A disc-shaped pitch / tilt control platform 9B integrally formed with the annular body 9A is provided in the cavity.

[0065] Combination Figure 5 The suspension system 11 shown in the example includes:

[0066] A fixing block 19 is provided at the center of the pitch / tilt control panel 9B, and the annular body 9A is integrally connected to the pitch / tilt control panel 9B through the fixing block 19.

[0067] Multiple sets of evenly distributed hydraulic components 20 extend radially from the fixed block 19;

[0068] A limiting ring 21 is provided in the radially extending direction and located at the edge of the pitch / tilt control panel 9B.

[0069] Combination Figure 5As shown, each limiting ring 21 has a through hole, and each hydraulic assembly 20 is provided with a movable block 22 for fixing the cable 23. The cable 23 configured in each movable block 22 passes through the through hole of the limiting ring 21 in the corresponding radially extending direction and is fixedly connected to the edge of the simulation stage 10 below.

[0070] The limiting ring 21 is located at the edge of the cavity and can be used to protect the cable 23 and prevent the cable 23 from being scratched. At the same time, it limits the position of the cable and the simulation stage to ensure position control and switching.

[0071] The pitch / tilt control panel 9B has a corresponding guide groove 24 arranged in the radial direction for each movable block 22. Each movable block 22 is engaged with the guide groove 24 and is limited and guided by the guide groove 24.

[0072] As an optional implementation, the hydraulic components 20 are distributed radially on the upper surface of the pitch / tilt control panel 9B, and are spaced apart from each other at 45-degree intervals.

[0073] Each pair of hydraulic components 20 arranged at a 90-degree angle and their corresponding cables 23 serve as the main control components, while the hydraulic components 20 and their corresponding cables 23 located between the two pairs of hydraulic components 20 arranged at a 90-degree angle serve as auxiliary control components.

[0074] Combination Figure 5 As shown, taking the configuration of 8 sets of hydraulic components 20 as an example, 4 sets of hydraulic components 20 and corresponding cables are set in the orthogonal direction. Between every two sets of hydraulic components 20 that are adjacent to each other at a 90-degree angle, another set of hydraulic components 20 and corresponding cables are arranged at a 45-degree angle.

[0075] It should be understood that the denser the configuration of the hydraulic components 20 and the corresponding cables 23, the more precise the attitude control, but the more complex the control strategy and process. Therefore, in the example of this invention, eight groups are used as an example for illustration.

[0076] During operation, flight trainees issue control commands through the control components in the cockpit 12. The operating system controls the movement of the hydraulic components 20 and the motor 8. The motor 8 controls the horizontal rotation of the turntable 9 by rotating. Multiple hydraulic components 20 change the length of the cable 23 by their respective extension and retraction control. Through the coordinated extension and retraction of multiple cables 23 (change in suspension length), the turntable 9 is driven to perform rotation, pitch, and roll offset movements. The superposition and coordination of the above three dimensions are used for flight simulation training.

[0077] Example 2

[0078] In the aforementioned embodiment 1, when the pitch and roll of the turntable 9 are completed by controlling the lifting and lowering of multiple cables 23 through multiple hydraulic components 20, it is achieved to a certain extent by gravity (that is, after the cables 23 are extended, they need to descend in the corresponding direction under the action of gravity). However, the force of gravity is constant, and in large-scale flight simulations, this kind of delay is easily amplified, resulting in unbalanced movements, which can be summarized as insufficient flexibility of the movements.

[0079] At the same time, due to the flexibility of the cable 23 itself, the extreme deviation will cause the direction to be unstable. Although the deviation can be corrected by the other cables 23, the movement will still be delayed due to inertia.

[0080] Therefore, in the embodiments of the present invention, by setting an adaptive buffer, the ball 16 engages with the annular groove 17 and slides with each other. Thus, when the rotating table 9 rotates horizontally, the ball 16 slides in the annular groove 17, so that the spring 15 will not deviate. When the rotating table 9 pitches, it will be affected by the spring 15.

[0081] When the turntable 9 descends, the force of the spring 15 will make it descend faster, thus achieving a flexible movement effect. During rapid horizontal movement, it can also restrict the turntable 9, making it less susceptible to excessive deviation caused by inertia.

[0082] Since the upward traction force can be adjusted at any time, the spring 15 changes with the stretching range. Therefore, the two interacting forces are constantly changing in real time, making the turntable 9 more flexible and precise in performing each corresponding action when pitching and rotating.

[0083] Furthermore, for the flexible cable 23, the relatively rigid structure of the spring 15 can effectively compensate for the defects of the cable 23, thus preventing the cable 23 from becoming entangled or misaligned.

[0084] Example 3

[0085] Because multiple actions are superimposed when an action is repeated, and it takes a period of time for the action effect to be achieved after the command is issued, the forces exerted during the next action are easily superimposed.

[0086] To achieve more precise control and switching of actions, such as Figure 5As shown, in this embodiment, based on embodiment 2, a first sensor 18 is installed on the upper surface of the support column 7 to detect the distance between the simulation platform 10 and the support column 7. This sensor, for example, is a ranging component based on laser or ultrasonic methods, and is connected to the control system to monitor the real-time position of the simulation platform. The first sensor 18 continuously detects the relative distance between the support column 7 (fixed position) and the moving simulation platform 10 at a preset sampling period, thereby feeding back the data to the control system for comparison, verification, and correction. It should be understood that the first sensor 18 is configured to connect and communicate with the control system wirelessly or via wired means.

[0087] In an optional embodiment, each limiting ring 21 is provided with a second sensor 26, which is used to monitor the extension length of the cable 23 in the corresponding radial extension direction. The second sensor 26 is connected to the control system signal via wireless communication and transmits the detection signal to the control system. The control system compares and verifies the length of the cable 23 and corrects the deviation.

[0088] Combination Figure 6 , 7 As shown, a rotatable pulley 25 and a second sensor 26 are provided inside the limiting ring 21. The cable 23 is embedded in the groove of the pulley 25, so that the linear movement of the cable 23 drives the pulley 25 to rotate synchronously and linearly. The second sensor 26 detects the rotation of the pulley 25 and thus detects the extension and retraction length of the cable. The pulley 25 can be designed with a U-shaped groove or a V-shaped groove.

[0089] In an embodiment of the present invention, the second sensor 26 is a photoelectric encoder or a Hall encoder. It monitors the extension length of the cable 23 by detecting the number of rotations of the pulley 25. When multiple motion control commands are issued, there is a deviation delay between the actions. The first sensor 18 feeds back the position distance monitored in real time to the control system, calculates and judges the posture of the turntable 9, and combines the data from the second sensor 26 with the feedback to the hydraulic component 20 to reduce / increase the extension amplitude or the number of rotations, so as to achieve more accurate action and realize the correction and deviation of the position of the simulation table.

[0090] Example 4

[0091] Combining the above embodiments and Figure 1-7 The multi-free flight simulation platform shown will be further explained in detail in the process of flight simulation trainees entering it for flight simulation training.

[0092] S1. In the initial state, the turntable 9 is stationary and supported by multiple support columns 7 on the base. At the same time, the spring 15 is also in a slightly stretched state (close to the initial state). After the trainee enters the cockpit 12, he fastens his seat belt in the seat and controls the system through the control components in the cockpit 12. During the system initialization phase, the control system starts and drives the hydraulic components 20 to synchronously retract multiple cables 23, thereby stretching the turntable 9 to a predetermined position. This position can be preset by the control system, leaving space in the lower part for pitching motion.

[0093] S2. Flight training personnel operate the control stick and other controls in the cockpit 12, and transmit electrical signals to the control system to control the operation of the motor 8 and hydraulic components 20.

[0094] S3. The control system calculates the electrical signals of the operation and controls the movement of the motor 8 and the hydraulic component 20 to drive the turntable 9 and the cable 23 respectively. The turntable 9 and the cable 23 cooperate to adjust the current attitude of the simulator 10. When rotating left and right, the drive motor 8 drives the turntable to rotate, which in turn drives the simulator to rotate. When performing pitch / roll movements, the hydraulic component 20 achieves this by extending and retracting the length of multiple cables 23. The two then work together to complete the flight simulation movement.

[0095] In a preferred embodiment, the first sensor 18 and the second sensor 26 monitor the position of the simulation platform 10 and the degree of cable 23 extension / retraction in real time, and feed this information back to the control system. This feedback is used to correct the operation of the motor 8 and the hydraulic assembly 20, adjusting the rotation angle / speed and the extension / retraction length / speed of the cable 23. For example, the first sensor 18 feeds back the real-time monitored position and distance to the control system, calculates and compares the actual posture of the rotating platform 9, and combines this with the data from the second sensor 26 to feed back to the hydraulic assembly 20, thereby reducing / increasing the extension / retraction amplitude or the number of rotations.

[0096] As an optional example, the feedback signal processed by the aforementioned first sensor 18 and second sensor 26 has a response speed of not less than 1ms to ensure the accuracy of the action, correct deviations in a timely manner, and prevent the action from becoming unbalanced.

[0097] While the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
