Description

Technical Field

[0001] The present application relates to the technical field of aircraft simulation training equipment, and in particular to a spherical screen type aircraft flight simulation training cabin. Background Art

[0002] The pilot is the core of safe aircraft operation. Whether in manned or unmanned aircraft, the pilot needs to operate the driving instruments to make the aircraft perform corresponding actions and complete the predetermined tasks.

[0003] Pilots need to undergo a lot of training before performing a mission alone. The training includes real-machine training and simulation training. Among them, simulation training has low cost and high safety factor, so it accounts for a large proportion of the entire training. In simulation training, a common training method is that pilots take a simulation training cabin to perform tasks in a simulated manner in a highly simulated environment, thereby gradually improving their ability to control the aircraft. Since it is necessary to display the simulated environment, a display device is required. Commonly used display devices are flat-panel displays, which cannot simulate the spherical field of view of the human eye. In order to improve the simulation effect, the prior art also uses a spherical projection screen. By projecting images onto the spherical projection screen, the field of view of the human eye can be simulated more realistically, such as CN116543620A and CN206893134U.

[0004] However, in the existing patents, the projectors are all installed on the top of the ball screen in an upside-down manner without any supporting structure underneath, which brings considerable difficulties to the installation and maintenance of the projector. Summary of the invention

[0009] The angle adjustment device is arranged on the inner frame, and is used to rotate the projector to a certain angle in response to the instruction input by the operator, so as to increase the available space inside the inner frame.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] Figure 1-8 The present invention provides a structural schematic diagram of a spherical screen type aircraft flight simulation training cabin provided in an embodiment of the present invention. The present invention provides a spherical screen type aircraft flight simulation training cabin, including:

[0033] Ball screen 10;

[0034] A projector mounting seat is arranged on the inner top surface of the ball screen 10. The projector mounting seat includes an inner frame 400. A projector 410 is arranged on the inner bottom surface of the inner frame 400. The projector 410 is used to project an image onto the inner side surface of the ball screen 10. An extension platform 430 is also arranged at the bottom of the inner frame 400. A folding ladder 431 is arranged at the bottom edge of the extension platform 430.

[0035] The angle adjustment device is disposed on the inner frame 400 . The angle adjustment device is used to rotate the projector 410 to a certain angle in response to an instruction input by an operator, thereby increasing the available space inside the inner frame 400 .

[0036] Exemplarily, the inner side of the ball screen 10 is a spherical surface, so when the projector 410 projects an image, the pilot can feel a real simulation effect through the spherical projection area.

[0037] In an embodiment of the present application, there are multiple projectors 410, and the multiple projectors 410 are respectively arranged at different positions on the inner bottom surface of the inner frame 400, and the orientations of the projectors 410 are different. After the multiple projectors 410 project corresponding images to different areas of the spherical screen 10 respectively, the multiple projected images are spliced ​​to form a complete projection image.

[0038] Furthermore, after using multiple projectors 410 to project images to different positions of the projection area at the same time, the field of view formed is 270° horizontally and 65° vertically. In the vertical field of view, the upper field of view is 35° and the lower field of view is 30°. Through large-scale projection, a huge field of view can be provided to the pilot, simulating the training environment more realistically.

[0039] The inner frame 400 can be formed by welding 10# channel steel. In addition to the need to set a plurality of projectors 410 on the inner bottom surface, an extension table 430 for operators to stand on needs to be set at the bottom of the outer side surface. Specifically, since the field of view of the projection area in the horizontal direction is 270 degrees, the projectors 410 are not evenly installed on the edge of the inner bottom surface of the inner frame 400, that is, there is a situation where the distance between two projectors 410 is greater than the distance between any other two adjacent projectors 410, and the extension table 430 is set at a position on the inner frame 400 corresponding to the area between the two projectors 410, so that the operator can enter and exit the inner frame 400 in a relatively ample space.

[0040] Since the projectors 410 in the present application are all arranged on the inner bottom surface of the inner frame 400, and one end of the projector 410 faces the inside of the inner frame 400, and the other end faces the outside of the inner frame 400, the space inside the inner frame 400 is relatively small, and the operator may not be able to carry out maintenance work in this limited space. Therefore, the present application also sets an angle adjustment device on the inner frame 400, so that when the operator needs to enter the inner frame 400, the normally working projector 410 is first rotated to a certain angle, thereby increasing the available space inside the inner frame 400.

[0041] Specifically, the angle adjustment device includes an instruction receiving unit and an angle control unit. The instruction receiving unit can adopt an input unit with or without display, such as a touch screen or a key panel, which includes control buttons corresponding to each projector 410. The input unit needs to include at least two buttons, "fold" and "reset", corresponding to each projector 410. The "fold" button is used to control the corresponding projector 410 to rotate a certain angle to free up space inside the inner frame 400, and the "reset" button is used to return the projector 410 to its initial position after folding for normal projection.

[0042] The angle control unit can use a stepper motor. Each projector 410 needs to be installed on the inner bottom surface of the inner frame 400 in a horizontal rotation, and each projector 410 rotates under the drive of an angle control unit to switch between the retracted and reset states. When the operator needs to enter the inner frame 400, the projector 410 that needs to be retracted can be determined according to the working conditions of each projector 410. Generally speaking, when a projector fails, the operator needs to change the projector 410 to the current position, and other projectors 410 that are working normally can be retracted. Therefore, the operator can select the projector 410 that needs to be retracted on the instruction receiving unit, and control the corresponding projector 410 to rotate a certain angle through the corresponding button, so that the projector 410 is in the retracted state. When the operator finishes the inspection of the projector 410, the command receiving unit is used to reset each retracted projector 410 again.

[0043] Furthermore, the instruction receiving unit can also use a single-chip microcomputer or a microprocessor to monitor the working status of each projector 410. When a fault is detected in any projector 410, the operator can set the other projectors 410 except the faulty projector 410 to a folded or reset state through one-click operation, thereby simplifying the operator's use.

[0044] Furthermore, the extension platform 430 can adopt a steel structure, and a folding ladder 431 is set on the bottom surface of one end thereof. When the folding ladder 431 is folded, it can be separated from the contact with the ground and hung under the extension platform 430, and the space occupied is very small. When the folding ladder 431 is opened, its bottom end can be in contact with the ground, and the operator can climb to the extension platform 430 through each step in turn.

[0045] In a possible embodiment, a hanging frame 310 is disposed on the outer side of the inner frame 400, a hanging plate is disposed on the hanging frame 310, an opening matching the projection port position of the projector 410 is disposed on the hanging plate, and the projection port of the projector 410 extends out from the opening.

[0046] Exemplarily, the hanging frame 310 may also be a steel structure, and the hanging plate arranged thereon is used to maintain the beauty of the hanging frame 310. Since the hanging plate is located on the outer side of the hanging frame 310 and the projector 410 is located on the inner side of the hanging frame 310, an opening needs to be provided on the hanging plate so that the light projected by the projector 410 can pass through the opening and illuminate the inner side of the spherical screen 10.

[0047] In the embodiment of the present application, a hanging opening is provided at the top of the dome 10, and a hanging plate 300 matching the hanging opening is provided at the top of the hanging frame 310, and the hanging plate 300 is overlapped on the top surface of the hanging opening.

[0048] After the hoisting opening is set on the ball screen 10, the top surface of the ball screen 10 is horizontal, and the formed hoisting opening is circular. Correspondingly, the hanging plate 300 should also be a circular or annular structure with the same shape as the hoisting opening but slightly larger than the hoisting opening. The hanging plate 300 can be connected to the top surface of the hoisting opening by bolts, and the hanging frame 310 is connected to the bottom surface of the hanging plate 300.

[0049] Furthermore, a hanging rod 420 is provided at the top of the inner frame 400, and the hanging rod 420 is connected to the inner side of the hanging plate 300. The hanging rod 420 can be a steel pipe, and the inner frame 400 and the hanging frame 310 can be connected together through the hanging rod 420 to ensure that the distance between the two is fixed and no relative movement occurs. At the same time, after the inner frame 400, the hanging frame 310 and the hanging plate are connected to the ball screen 10, the ball screen 10 forms a closed system, and a sunshade can be provided on the hanging rod 420 and the hanging plate to prevent the external light from adversely affecting the projection effect inside the ball screen 10.

[0050] At the same time, since the dome 10 is large in size and is a closed space, an echo is easily generated inside it when playing audio. In order to reduce the impact of the echo, a sound-absorbing panel can be set inside the dome 10, for example, outside the inner side projection area, outside the hanging board or on the ground. The sound-absorbing panel can be a porous structure, and the reflected sound vibration can be limited to a limited space and gradually absorbed through multiple suction holes, thereby absorbing most of the sound and reducing the generation of echoes.

[0051] In a possible embodiment, the spherical screen 100 is formed by splicing a plurality of spherical screen petals 100 .

[0052] For example, the number of the spherical curtain petals 100 may be 8. When the 8 spherical curtain petals 100 are completely spliced ​​together, a 360° surrounding structure in the horizontal direction can be formed. Therefore, the central angle of each spherical curtain petal 100 in the horizontal direction is 45°.

[0053] In the embodiment of the present application, the ball screen flap 100 includes an inner panel 110 and an outer panel 120, both of which are spherical structures, and the inner panel 110 and the inner panel 120 are connected by a sandwich frame 130. The sandwich frame 130 can be a steel plate frame with the same shape as the inner panel 110 and the outer panel 120, and the front and rear sides of the sandwich frame 130 need to be coated with high-strength composite glue to bond the outer panel 120 and the inner panel 110 to the inner and outer sides of the sandwich frame 130, respectively.

[0054] Furthermore, the inner plate 110 and the outer plate 120 are both made of glass fiber reinforced plastics, and a gain paint is coated on the inner side of the inner plate 110. Specifically, the gain paint can be a D-type projection paint, and the relatively smooth surface on the inner side of the inner plate 110 can be made rough by coating the gain paint, so that the light transmitted by the projector 410 is diffusely reflected on the surface of the gain paint, thereby improving the display effect of the ball screen 10.

[0055] Furthermore, the edges of both sides of each spherical curtain petal 100 are respectively provided with a convex plate 101 and an overlapping edge, and the convex plate 101 and the overlapping edge match each other, and the convex plate 101 of one spherical curtain petal 100 and the overlapping edge of the other spherical curtain petal 100 of two adjacent spherical curtain petals 100 are overlapped together, and the overlapping parts are connected together by a plurality of connecting members 102, so that the two adjacent spherical curtain petals 100 are stably connected. Specifically, the connecting member 102 can be a countersunk hexagon socket screw, and the spherical curtain 10 can be formed by connecting a plurality of spherical curtain petals 100 end to end in sequence.

[0056] In a possible embodiment, a mounting base is further included, and the spherical screen 10 is disposed on the mounting base.

[0057] For example, the mounting base can be a steel frame or a flat plate structure. No matter which structure is used, a position for mounting the ball screen 10 and the simulation cabin needs to be reserved thereon. Specifically, expansion bolt holes can be reserved on the mounting base to facilitate the installation of the ball screen 10 and the simulation cabin using expansion bolts.

[0058] In the embodiment of the present application, in order to facilitate the transportation of the installation base, a splicing structure can be used, which can be divided into multiple sub-bases 200. After the multiple sub-bases 200 are installed on site, they can be spliced ​​to form a complete installation base.

[0059] Furthermore, in order to prevent the simulated cockpit from transmitting vibration to the mounting base when it moves, a mounting groove 210 matching the simulated cockpit can be reserved on the mounting base. When the mounting base is installed on the ground, the mounting groove 210 will expose the ground so that the simulated cockpit can be fixed on the ground by expansion bolts.

[0060] In a possible embodiment, a rear room is further included. An entrance and exit are arranged at the bottom of the ball screen 10. The rear room is connected to a position on the outer surface of the ball screen 10 corresponding to the entrance and exit. The interior of the rear room is used to place control equipment.

[0061] Exemplarily, the control device mainly includes a computer for controlling the projector 410 and the simulated cockpit, and auxiliary equipment such as tables and chairs for operators to operate the computer conveniently.

[0062] In an embodiment of the present application, the rear room body is also installed on the mounting base. At the same time, in order to hide the cables, wire tubes for passing the cables can be pre-buried in the mounting base. After installing the projector 410, the simulation cockpit, the computer and other equipment, the cables can be connected between the various devices through the wire tubes, thereby improving the aesthetics of the interior of the dome screen 10.

[0063] Furthermore, the rear room body includes a room panel 500 and a door panel 510 at the opening of the rear room body. The room panel 500 includes a plurality of vertical panels and horizontal panels, and the vertical panels and the horizontal panels are also spliced ​​to form the main body of the rear room body. At the same time, the vertical panels and the horizontal panels also need to match the shape of the ball curtain 10 to keep the connection between the rear room body and the ball curtain 10 sealed.

[0064] After the vertical plate and the horizontal plate are spliced ​​together, the door panel 510 can be installed at the opening by pushing, pulling or hinged manner to facilitate the opening and closing of the door panel 510.

[0065] Although the preferred embodiments of the present application have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present application.

[0066] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
