Description

Technology Field

[0001] The present invention relates to a VR simulator for a self-propelled artillery driver.

[0002] More specifically, the invention relates to a VR-based stand-alone self-propelled artillery driver simulator, characterized by linking the simulator and a central control unit via a network server, collecting training information and transmitting it to a central control unit to implement realistic feedback within the limited performance of the safety system, steering system, display device, camera, motion bed, etc., equipped in the simulator, and then comparing this information with actual self-propelled artillery driving information to deliver realistic feedback to the simulator. Background Technology

[0004] Self-propelled artillery equipped with projectiles, such as the K9A1, requires highly skilled operation because errors in control can lead not only to serious situations but also to casualties resulting from accidental firing.

[0005] Accordingly, training is conducted in various ways, and among these, control training is carried out using a control simulator.

[0006] However, conventional simulated control devices are equipped in the form of integrated systems based on actual vehicles, which not only occupies a large amount of space but also has the problem of being unuseful due to a lack of intuitiveness.

[0007] Furthermore, although it is designed so that screen recognition is achieved through the background displayed on monitors, screens, etc. placed in front of the driver, there is a problem in that it fails to provide the driver with a background identical to the actual background including the driving path, as well as failing to provide driving information regarding the simulated driving.

[0008] Accordingly, although various technologies are being developed to provide simulated control devices for self-propelled artillery, there is a problem where trainability is reduced because the gap between actual control and simulated control has not been narrowed. Prior art literature

[0014] In addition, another problem to be solved by the present invention is to provide a VR simulator for a self-propelled artillery driver that can minimize problems such as collisions or deviations from the path by reducing blind spots during night driving and reversing, by providing a shooting unit composed of a driver's night periscope and a rear camera, and a video display unit for identifying this inside the control chamber.

[0015] In addition, another problem that the present invention aims to solve is to provide a self-propelled artillery driver VR simulator that can prevent safety accidents by avoiding collisions with the driver caused by turret rotation, by restricting the turret's rotation movement when the hatch of the control chamber is detected to be open. means of solving the problem

However, the present invention is not limited to the embodiments disclosed below but may be implemented in various different forms. These embodiments are provided merely to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined only by the scope of the claims. Throughout the specification, the same reference numerals refer to the same components.

[0030] In describing the embodiments of the present invention, if it is determined that a detailed description of known functions or configurations could unnecessarily obscure the essence of the invention, such detailed description will be omitted. Furthermore, terms and words used in this specification and claims are defined in consideration of their functions in the embodiments of the present invention and should not be interpreted as being limited to their ordinary or dictionary meanings. Instead, based on the principle that the inventor can appropriately define the concepts of terms to best describe their invention, they must be interpreted in a meaning and concept consistent with the technical spirit of the present invention.

[0032] Therefore, the embodiments described in this specification and the configurations illustrated in the drawings are merely the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention; thus, it should be understood that various equivalents and modifications that can replace them may exist at the time of filing this application.

[0034] Before proceeding with the following description with reference to the drawings, it should be noted that matters not necessary to reveal the gist of the invention, namely known configurations that a person skilled in the art with ordinary knowledge can obviously add, have not been illustrated or described in detail.

[0036] First, before describing various embodiments of the present invention in detail with reference to the attached drawings, it should be noted that terms such as directions of components described in the following detailed description or illustrated in the drawings (e.g., "front," "back," "left," "right," "up," "down," "up," "down," "transverse," "longitudinal," "front," "rear," "one side," "other side," "inner side," and "outer side") do not merely indicate or imply that they must have a specific direction, and that such description of directions is intended to facilitate the explanation of the components with reference to the attached drawings.

[0038] The self-propelled artillery driver VR simulator according to the present invention relates to a VR-based stand-alone self-propelled artillery driver simulator, characterized by linking the simulator and a central control unit via a network server, collecting training information and transmitting it to a central control unit to implement realistic feedback within the limited performance of a safety system, steering system, display device, camera, motion bed, etc., provided in the simulator, and then comparing it with actual self-propelled artillery driving information to deliver realistic feedback to the simulator.

[0040] Hereinafter, a VR simulator for a self-propelled artillery driver according to the present invention will be described in detail with reference to the attached drawings.

[0042] FIG. 1 is a perspective view of a self-propelled gun driver VR simulator according to the present invention, and FIG. 2 is a perspective view schematically showing the internal configuration of a self-propelled gun driver VR simulator according to the present invention.

[0044] The self-propelled gun driver VR simulator according to the present invention is configured to maximize training immersion by providing a driver with various environments for actual self-propelled gun driving and implementing feedback similar to reality, and comprises a driving chamber (100), an input unit (200), an output unit (300), a shooting unit (400), a database unit (500), a communication unit (600), a motion bed (700), a ladder (800), and a control unit (900).

[0046] The control chamber (100) provides a space for simulating the control of the self-propelled gun and can be made of a box-type as shown in the attached drawing.

[0047] This control chamber (100) is provided with a space to provide various training courses for self-propelled artillery so that one can acquire skills to control a real self-propelled artillery, and is equipped with an input unit (200), an output unit (300), a shooting unit (400), a database unit (500), a communication unit (600), and a control unit (900) to be described later, and is provided with a ladder (800) on the outside to provide a path for boarding through a hatch, and is a stand-alone simulator installed on the ground by a motion bed (700), and is made of a box-type type so as to improve the sense of training immersion by enabling the input unit (200) of a real self-propelled artillery as well as space utilization.

[0048] Meanwhile, although the shape of the control chamber (100) in FIG. 1 is depicted as a box shape, it is obvious that it can be formed in any shape as long as the internal space and external space of the control chamber (100) for control are formed separately depending on the design conditions.

[0049] Furthermore, since the control chamber (100) is manufactured from a material that is lighter than that of an actual self-propelled gun, it has the advantage of being easy to move as well as space utilization due to its lightweight design.

[0050] Additionally, the control chamber (100) is installed on the ground by a motion bed (700) to be described later. At this time, in order to allow the control chamber (100) to move smoothly, a wheel (caster) equipped with a locking device may be provided on the lower side of the motion bed (700) supported on the ground, or a through hole formed in the front and rear so that a forklift fork may be inserted into the bottom, or a separate hook may be provided on the top or side so that it can be hooked onto a crane, etc.

[0051] Here, a wheel (caster) refers to a wheel that performs rolling motion to facilitate the movement of heavy objects.

[0053] FIG. 3 is a configuration diagram showing the input section of a self-propelled gun driver VR simulator according to the present invention.

[0055] The input unit (200) is provided inside the control chamber (100) and performs the function of receiving information for control and outputting a result value according to the input control information, outputting it as an image through the output unit (300) described later, or transmitting it to a central control unit through the communication unit (600). It is configured to include a steering wheel assembly (210), a gear lever assembly (220), an accelerator pedal assembly (230), a brake pedal assembly (240), a parking brake pedal assembly (250), and a light speed control switch (260).

[0056] In addition, the input unit (200) can be configured with various components such as handles or buttons that are provided in actual self-propelled guns.

[0058] The steering wheel assembly (210) performs the function of adjusting the steering reaction force of the steering wheel. When a driver controls a steering wheel equipped with a non-contact potentiometer, it obtains information for adjusting the steering reaction force and outputs it through the output unit (300) described later or transmits it to a central control unit through the communication unit (600) to notify the manager and the driver.

[0059] At this time, the information value obtained by the steering handle assembly (210) can be designed so as not to exceed a left / right steering angle of about 25 degrees and a steering shaft driving force of about 30 kgf.

[0060] This allows the driver to obtain the same experience as the actual steering of the self-propelled gun when controlling motion driving. When the above reference value is exceeded, such training information is collected and transmitted to the central control unit, and then fed back through the output unit (300) described later, thereby enabling the driver to perform correct steering for actual self-propelled gun driving.

[0062] The shift lever assembly (220) performs the function of preventing automatic shifting when shifting to "D", "N", or "R" positions, thereby preventing problems where shifting is not performed accurately.

[0063] More specifically, a separate lever is provided for shifting to occur, and shifting is performed as a subsequent operation only when the lever is operated first, whereas the lever operation angle can be detected through a non-contact potentiometer when the lever is operated.

[0064] This allows the operator to provide feedback on whether the lever operation has been performed correctly, thereby providing feedback on whether the shifting is accurate when shifting is required, and furthermore, by restricting the shifting from occurring if the lever is not pre-operated, it prevents the problem of inaccurate shifting.

[0066] The accelerator pedal assembly (230) performs the function of acceleration. When controlling an accelerator pedal equipped with a non-contact potentiometer, if the operator applies pressure to the accelerator pedal, it acquires acceleration information corresponding to the pressure and outputs it through the output unit (300) described later or transmits it to a central control unit through the communication unit (600) to notify the manager and the operator.

[0067] Here, pedal force refers to the force required to step on the pedal.

[0068] Accordingly, the driver can obtain feedback regarding the amount of pedal force used to control the accelerator pedal during the process, thereby enabling motion training on how the actual acceleration of the self-propelled gun is achieved.

[0070] The brake pedal assembly (240) performs a braking function and, when controlling a brake pedal equipped with a non-contact potentiometer, acquires braking information corresponding to the braking force when the operator applies pressure to the brake pedal, and outputs this information through the output unit (300) described later or transmits it to a central control unit through the communication unit (600) to notify the manager and the operator.

[0071] Accordingly, the driver can obtain feedback regarding the amount of pedal force used to control the brake pedal during the process, thereby enabling motion training on how the actual braking of the self-propelled artillery is performed.

[0073] The parking brake pedal assembly (250) performs the function of limiting the maximum fixed angle when parking the self-propelled gun and refers to a brake system operated by pulling a lever by hand.

[0074] This parking brake pedal assembly (250) is equipped with a limit sensor to determine whether the parking brake pedal has been operated, and outputs the result through the output unit (300) described later or transmits it to the central control unit through the communication unit (600) to notify the manager and the operator.

[0075] Accordingly, when the self-propelled gun is parked on an inclined surface during a simulated training, feedback can be obtained through the parking brake pedal assembly (250) regarding whether the parking brake has been actuated, thereby enabling training on what situation the actual parking brake of the self-propelled gun should be actuated.

[0077] The light speed control switch (260) performs the function of controlling the light speed by switching between the headlights and high beams, and may be composed of a push button switch for operation and a dimmer switch for controlling the light speed.

[0078] The push button switch is configured to switch between the headlights and high beams through the action of the operator pressing it, and to adjust the beam speed through the operation of the dimmer switch.

[0079] The resulting output is output through the output unit (300) described later or transmitted to the central control unit through the communication unit (600) to notify the manager and the driver, thereby enabling training on whether the headlights or high beams of the self-propelled gun are used correctly in sections where beam speed adjustment is required.

[0081] The input unit (200) acquires information regarding the operation of devices such as a steering wheel, accelerator pedal, brake pedal, parking brake pedal, and light speed control switch provided within the control chamber (100), outputs this information through the output unit (300) or transmits it to a central control unit through the communication unit (600), and provides feedback after comparing it with information regarding actual self-propelled gun operation, thereby enabling the manager and driver to conduct proper simulation training regarding the driving of the self-propelled gun.

[0083] The output unit (300) performs the function of outputting information about the simulated drive and is configured to include a front monitor (310), a periscope (320), a video display (330), a VR HMD, and an observation monitor (340).

[0084] This output unit (300) can be configured to output a result value according to the control information input from the input unit (200).

[0085] At this time, the output unit (300) can be configured to display in various languages, thereby enabling multinational language usage in various countries.

[0086] In addition, the output unit (300) is equipped with a microphone and a speaker in addition to video, so that voice communication is possible and sound notifications are made.

[0088] The front monitor (310) is provided outside the control chamber (100) and is for outputting images, and is configured to output driving images including background, driving path, surrounding environment information, or driving information of the self-propelled gun stored in the database unit (500).

[0089] This front monitor (310) can be configured to secure a wide left-right viewing angle by arranging the wide monitor horizontally, thereby allowing the entire content required for training to be placed on one screen so that visual information can be checked correctly and intuitively with the naked eye.

[0090] At this time, the front monitor (310) can be positioned on the upper front side of the outside of the control chamber (100) as shown in FIG. 1 so that the operator can visually check it.

[0091] This means that when a pilot wants to visually observe the outside of the control chamber (100) using a periscope (320) inside the control chamber (100), the external image shown by the periscope (320) is output through a front monitor (310) located on the front side of the periscope (320), thereby allowing the pilot to visually identify the external image inside the control chamber (100).

[0092] Additionally, when the driver opens the hatch provided in the control chamber (100) and wishes to directly observe the outside of the control chamber (100) with the naked eye, the driver opens the hatch and extends their head outward from the control chamber (100) to directly observe the front monitor (310) with the naked eye, thereby enabling identification of the image seen from the outside of the actual self-propelled gun.

[0093] That is, the front monitor (310) can display an image of the actual self-propelled gun from outside the gun on the monitor, thereby allowing the driver to perform training identical to driving the self-propelled gun on an actual road.

[0095] A periscope (320) is provided inside the control chamber (100) and allows the image output to the front monitor (310) to be visually identified.

[0096] That is, when the driver wants to visually observe the outside of the self-propelled gun from inside the control chamber (100), a periscope (320) is used, and in the simulator, the image output to the front monitor (310) is made visible through the periscope (320), thereby allowing training to visually observe the external image from inside the control chamber (100).

[0097] At this time, as shown in FIG. 1, a plurality of periscopes (320) may also be provided for identifying a wide range outside the control chamber (100) as a plurality of front monitors (310) are provided.

[0099] The video display unit (330) is provided together with the periscope (320), is provided inside the control chamber (100), and performs the function of outputting video information captured through the shooting unit (400) described later.

[0100] This video display (330) can identify video information captured through the shooting unit (400), such as a rear camera installed outside the control chamber (100), thereby reducing blind spots during night driving and reversing, and minimizing problems such as collisions or deviation from the path.

[0101] At this time, the image display (330) can be configured as a pair with periscopes (320) provided on each side, as described with reference to FIG. 2, and an image display (330) can be provided between them.

[0102] That is, as the image display (330) is positioned in front of the driver, that is, between a pair of periscopes (320) that require securing multiple fields of view, the driver can easily identify images with the naked eye through the image display (330) located in the center.

[0104] The VR HMD is equipped to be worn on the driver's head, and in the process of the driver checking video images with the naked eye, the driver can selectively check the front monitor (310) directly with the naked eye, check it with the naked eye through a periscope, or obtain actual vehicle operation information through the VR HMD, thereby enabling an immersive training environment.

[0106] The observation monitor (340) is provided outside the control chamber (100) and performs the function of displaying and outputting a screen output from the front monitor (310), a screen output from the video display (330), or a screen output from the VR HMD.

[0107] This observation monitor (340) allows the driver to visually observe the view from inside the control chamber (100) from outside the control chamber (100), and is used to check recorded video of training stored in the database unit (500) or for a separate observer to observe in real time from outside while the driver is controlling.

[0108] At this time, the observation monitor (340) is configured as a touchscreen so that the response speed according to the operation can be minimized.

[0109] Additionally, the observation monitor (340) can be configured to allow for, for example, six screen divisions.

[0110] This allows information about multiple simulators to be displayed on the observation monitor (340) via a split screen during the process of joint training by connecting multiple simulators to a network, and furthermore, prevents training from being delayed through a quick response to touch operation.

[0111] Furthermore, the observation monitor (340) can be configured so that a video image for outputting the pilot's field of view and a video image for checking the training situation are output separately through the splitting function of the observation monitor (340).

[0113] The camera unit (400) is composed of a driver's night periscope and a rear camera, enabling the acquisition of video information necessary for night driving and reversing.

[0114] That is, by enabling the acquisition of front and rear image information at night through the camera unit (400) and further enabling the acquisition of rear information even during the day, and by outputting this through the image display (330) so that the driver can identify it, training is performed to reduce blind spots during night driving and reversing so that collisions or deviations from the path do not occur.

[0116] The database section (500) stores information regarding the driving of the self-propelled gun, such as background, driving path, surrounding environment information, driving information of the self-propelled gun, and road map.

[0117] It is desirable that the database section (500) update the stored information in real time, and it can be configured so that new information is input and stored through the input section (200).

[0119] The communication unit (600) performs the function of transmitting and receiving data through mutual wired and wireless communication between multiple simulators, and the simulator and the central control unit are connected to a network to transmit and receive data.

[0120] That is, the communication unit (600) can support joint training by enabling a network system for multiple simulators to communicate with each other to be implemented.

[0121] Furthermore, the communication unit (600) can be configured to communicate with a separate terminal such as a smartphone or tablet.

[0123] FIG. 4 is a perspective view showing a motion bed in a self-propelled gun driver VR simulator according to the present invention.

[0125] The motion bed (700) performs the linear and rotational motion functions of the control chamber (100) and is configured to include a drive unit (710).

[0126] This motion bed (700) is designed to allow the operator to feel a sense of realism similar to reality in a virtual reality environment, and to feel sensations such as vibration and shock based on the operation information of the actual self-propelled gun.

[0127] In other words, it enables the implementation of an immersive training environment.

[0129] The driving unit (710) is coupled to the lower side of the control chamber (100) and consists of three parts, arranged radially spaced apart from each other.

[0130] This drive unit (710) is a crank rod type drive actuator operated by a servo electric motor, and transmits the linear motion generated as the crank pin rotates to the bottom side of the control chamber, thereby enabling the control chamber (100) to move up and down in a linear motion (heave).

[0131] In addition, as shown in FIG. 4, the plurality of driving units (710) are spaced apart from each other and are provided in three, thereby enabling forward and backward rotational movement (Pitch) and left and right rotational movement (Roll).

[0132] Accordingly, the motion bed (700) composed of three drive units (710) is configured to enable up-and-down linear movement (Heave), forward-and-backward rotational movement (Pitch), and left-and-right rotational movement (Roll), thereby enabling the realization of even minute shaking according to the movement of the actual self-propelled gun, which can maximize the sense of immersion in training.

[0133] In addition, the movement that occurs during the process of the driver controlling the control chamber (100) through the input unit (200) can be implemented to be identical to the movement that occurs during actual self-propelled gun driving.

[0134] For example, if there are obstacles such as separate objects or hills on the driving path, the driving unit (710) is operated by implementing the actual movement of the self-propelled gun during the process of passing through them, so that the control chamber (100) implements linear and rotational movements, allowing the user to feel the realism of avoiding actual obstacles or going over hills.

[0136] Figure 5 is a diagram showing an example in which the inclination angle of a ladder is adjusted in a self-propelled gun driver VR simulator according to the present invention.

[0138] A ladder (800) is provided outside the control chamber (100) and provides a path for boarding the hatch.

[0139] At this time, the ladder (800) can be configured so that the angle of inclination is adjusted, as shown in FIG. 5.

[0140] This allows the angle of inclination to be adjusted at various angles depending on the self-propelled gun model to provide safety during the process of boarding through the hatch where the driver enters and to achieve a boarding sensation similar to that of an actual self-propelled gun.

[0141] For example, referring to FIG. 5, the ladder (800) may be configured to be rotatable on the side of the control chamber (100), and may be configured to be fixed by a separate locking device after rotation. That is, it may be configured to be fixed at the adjusted position after the angle of inclination is freely adjusted.

[0142] Accordingly, the driver can train to board the actual self-propelled gun through the hatch, thereby reducing the time required for boarding and increasing proficiency.

[0144] FIG. 6 is a configuration diagram showing the control unit in a self-propelled gun driver VR simulator according to the present invention.

[0146] The control unit (900) performs the function of controlling the operation of the self-propelled gun driver VR simulator according to the present invention and is configured to include a single training module (910), a joint training module (920), a driving module (930), an evaluation module (950), a unique ID management module (960), and a safety module (970).

[0147] This control unit (900) performs the function of controlling the entire operation of the simulator.

[0149] The single training module (910) performs the function of single training of the simulator.

[0150] This single training module (910) can be configured to be selected through the input unit (200), and during single training, the operator can select the corresponding mode to conduct independent training.

[0152] The joint training module (920) performs the function of joint training between multiple simulators connected by the communication unit (600).

[0153] That is, through the communication unit (600), multiple simulators can communicate by implementing a network system, thereby enabling joint training.

[0154] Furthermore, it can be configured to enable multiple multi-training sessions using multiple simulators and VR on multiple PCs (desktops) via a network.

[0155] For example, two simulators and four PCs using VR can be connected via a network to enable a total of six training devices to train together.

[0156] At this time, the joint training video of the six units can be output from a single training unit, and preferably, the video is output through the observation monitor (340) of a selected simulator. Furthermore, when the joint training video is output through a single observation monitor (340), it can be configured to be divided into six screens so that the video of multiple training units is output separately.

[0157] This joint training module (920) can be configured to allow the driver to select a sky view video output so that multiple simulators, i.e., multiple self-propelled guns, participating in the training can all be displayed on the monitor.

[0158] Accordingly, by enabling the driver to share driving information, routes, and surrounding environment information of multiple self-propelled guns through the output of sky view video, the correct driving of multiple self-propelled guns can be achieved simultaneously, and furthermore, the judgment and senses to avoid collisions or interference between self-propelled guns can be trained.

[0160] The driving module (930) performs the function of outputting information regarding the driving of the self-propelled gun through the output unit (300) and is configured to include a map generation module (931).

[0161] This driving module (930) outputs information about the self-propelled gun currently in motion through the front monitor (310), the observation monitor (340), and the video display (330).

[0162] At this time, during joint training, the driving module (930) allows the driver to select a road view or a sky view to output an image, thereby enabling training of judgment and sense regarding where each of the multiple self-propelled guns is located or whether the entire formation of the multiple self-propelled guns is well maintained.

[0163] At this time, the driving module (930) may be configured to include an obstacle identification module.

[0164] The obstacle identification module provides location information where special terrain exists along the path the self-propelled artillery travels, such as urban areas, curved terrain, and side slopes, as well as obstacle information where separate obstacles exist along the path, such as vertical obstacles or trenches.

[0165] That is, the obstacle identification module drives the motion bed (700) through the driving module (930) when driving the self-propelled gun in an environment where special terrain or separate obstacles exist, thereby controlling the tilt of the control chamber (100) and enabling the driver to develop the ability to judge whether driving the self-propelled gun is possible or impossible.

[0167] The map generation module (931) performs the function of generating a training course map based on surrounding environment information such as starting location, weather, training course, terrain features, arrival location, etc., based on information stored in the database unit (500), information received from the central control unit through the communication unit (600), or information input through the input unit (200).

[0168] This map generation module (931) provides a navigation function that sets the starting point and the destination point when a driver trains to drive a self-propelled gun, and further provides information to enable driving operations according to the weather, and provides information on driving speed and driving method, such as urban areas, roads, or unpaved roads, so that driving training can be performed in various actual environments.

[0170] The display module (940), together with the driving module (930), performs the function of outputting information according to the display situation of the self-propelled gun through the output unit (300).

[0171] This display module (940) can be selected through the input unit (200) or the control unit (900) and allows training in a special situation called a display.

[0172] Furthermore, the display module (940) allows for training in movement, path search, and formation maintenance according to the training guidelines during joint training, such as the dispersion or assembly of multiple self-propelled guns.

[0173] For example, during joint training, if an enemy appears in front while multiple self-propelled guns are driving in a line along a city road via the driving module (930), training is conducted to have multiple self-propelled guns spread out to the left and right in accordance with training guidelines.

[0174] This training can be improved by notifying the driver through the output unit (300) and providing feedback on whether the self-propelled gun has driven.

[0176] The evaluation module (950) performs the function of creating a database of actual training content after training and storing it in the database unit (500), and then comparing the stored actual training content with the training guidelines stored in the database unit (500) and comparing it with the actual self-propelled gun driving information stored in the central control unit, and then producing and outputting a report.

[0177] In other words, through the reporting of training performance, pilots can review the evaluation of the relevant training, quantify it, and obtain objective evaluation indicators.

[0178] Here, scoring is performed by checking items such as the starting time, the method of passing a specific path (course), or the time required through the operation of the input unit (200), and by scoring and outputting them, it is possible to determine pass or fail based on a certain score and also assign a grade.

[0179] Accordingly, the pilot can provide feedback on the strengths, weaknesses, and shortcomings of the training, thereby allowing for the improvement of various issues and maximizing the effectiveness of the training.

[0181] The unique ID management module (960) determines the grade for each pilot through the pilot's personal information and performs the function of determining the promotion, omission, or demotion of the grade according to the result output through the evaluation module (950).

[0182] At this time, the unique ID management module (960) can be configured to allow the selection of a sky view that can be output through the output unit (300) according to the pilot's grade.

[0183] For example, when the driver's rank is low, the sky view can be selected through the output unit (300), allowing the driver to observe the entire surrounding environment while driving the self-propelled gun and to recognize terrain features at a glance, thereby enabling the driver to focus on training to develop their senses. When the driver's rank is promoted beyond a certain standard, the sky view cannot be selected through the output unit (300), so only the screen displayed on the actual self-propelled gun is output, thereby improving the driver's proficiency and judgment.

[0184] Furthermore, the unique ID management module (960) can be configured to store the pilot's own unique data by inputting the individual's military ID number through the input unit (200).

[0185] In other words, by entering military identification numbers for all operations, such as simulator operations and data collection, security can be enhanced, and training performance can be improved by providing feedback to each individual pilot regarding missing information during training.

[0187] The safety module (970) performs the function of restricting the traverse movement of the turret when the hatch of the control chamber (100) is detected to be open.

[0188] That is, when training for the rotation of the turret is being conducted in the control chamber (100), if the hatch provided in the control chamber (100) is detected by a sensor to be open, the safety module (970) can automatically restrict the rotation of the turret to prevent the occurrence of a safety accident.

[0189] Meanwhile, in actual self-propelled guns, accidents frequently occur where the turret rotates and the driver gets trapped in the turret, resulting in death or injury, even though the driver has opened the hatch and is out. In the self-propelled gun driver VR simulator according to the present invention, a safety module (970) is provided so that the driver can be trained to automatically restrict the rotation of the turret when the hatch is open, thereby preventing safety accidents from occurring.

[0191] According to this configuration, the VR simulator for a self-propelled gun driver according to the present invention relates to a VR-based stand-alone self-propelled gun driver simulator, wherein the simulator and the central control unit are linked via a network server, and training information is collected and transmitted to the central control unit to implement realistic feedback within the limited performance of the safety system, steering system, display device, camera, motion bed, etc. equipped in the simulator, and then compared with actual driving information of the self-propelled gun to deliver realistic feedback to the simulator, thereby maximizing the sense of immersion in training.

[0192] In addition, the present invention can create an immersive training environment by allowing a sense of realism similar to reality to be felt in a virtual reality environment through VR equipment.

[0193] In addition, the present invention enables multi-training using multiple PCs (desktops) as well as multiple independent simulators by implementing a network system, thereby allowing for individual or joint training and enabling the operator to acquire various information.

[0194] In addition, the present invention is equipped with a shooting unit (400) consisting of a driver's night vision periscope and a rear camera, and an image display (330) for identifying this is provided inside the control chamber (100), thereby reducing blind spots during night driving and reversing, so that problems such as collisions or deviations from the path can be minimized.

[0195] In addition, the present invention can prevent safety accidents by restricting the turret's rotational movement when the hatch of the control chamber (100) is detected to be open, thereby avoiding collisions with the driver caused by the turret's rotation.

[0197] Although various embodiments of the present invention have been presented and described in the above description, the present invention is not necessarily limited thereto, and those skilled in the art will understand that various substitutions, modifications, and changes are possible within the scope of the technical concept of the present invention.
