It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.

Like reference numerals refer to like elements throughout the specification.

Hereinafter, a training fire extinguisher for a virtual reality according to an embodiment of the present invention will be described with reference to FIG. 1 to FIG. 1 is a view for explaining a training fire extinguisher of a virtual reality according to an embodiment of the present invention. 2 is a view for explaining an image displayed to a user in a training fire extinguisher of a virtual reality according to an embodiment of the present invention. 3 is a view for explaining an example in which a plurality of persons are trained together in a training fire extinguisher of a virtual reality according to an embodiment of the present invention.

The training fire extinguisher of the virtual reality according to the embodiment of the present invention includes the fire extinguisher model 10, the first, second and third sensors 21, 22 and 23, the control unit 30 and the communication unit 40 .

Although the external configuration of the fire extinguisher model 10 is the same as or similar to the external appearance of a conventional fire extinguisher, it is possible to provide a full-body part such as the sensors, the control unit, and the communication unit, A wired power cable may be connected.

1, the fire extinguisher model 10 includes a lever 13 provided on the upper side of the body 14, a safety pin 11 on which the operation of the lever 13 is suppressed, And a nozzle 12 connected to the upper side of the nozzle 12.

In particular, the fire extinguisher model 10 may be free to move and not be fixed at a particular location. In other words, fire extinguishers installed for training or training purposes known in the art were fixed to the floor or fixed to a desk-like structure. As a result, the nozzle already has a posture directed to a certain direction, and the water stem is fired when the lever is gripped after removing the safety pin. That is, a fire extinguisher installed for a conventionally known education or training purpose can predict where the fire will occur, so that the educational effect may not be high. Even fire extinguishers, which are installed for training or training purposes as known in the art, remain at the experience level of launching water streams, so that there is a very different problem in the actual fire scene and situation.

However, the training fire extinguisher of the virtual reality according to the embodiment of the present invention can not predict from which position the fire of a certain size occurs before the fire extinguisher usage instruction is educated, thereby allowing the experimenter to maintain the tension. Particularly, in the training fire extinguisher of the virtual reality according to the embodiment of the present invention, the experient can carry the fire extinguisher model 10 to find a fire extinguisher in a situation where the fire occurs, This is very similar to the fire suppression in real fire scenes.

The first sensor 21 outputs a first signal when the safety pin 11 is removed. When the first signal is generated, it can be understood as an expression of a will to actually use the fire extinguisher.

The second sensor 22 detects the posture and movement of the nozzle 12 and outputs the posture and movement of the nozzle 12 as a second signal. Before the second signal is generated, the nozzle 12 may be in an orientation in which it is aligned with the fire extinguisher model 10, e.g., mounted on a clamp. Then, when the second signal is generated, it can be understood that the experimenter is holding the nozzle 12 and moving artificially, and more specifically, aiming at the fire point.

That is, the training fire extinguisher of the virtual reality according to the embodiment of the present invention can experience a series of operations for the fire extinguisher after the experimenter recognizes the occurrence of the fire, take out the nozzles aligned in the fire extinguisher, and aim at the fire point There is a realistic advantage because it can be experienced almost similar to using a real fire extinguisher.

The third sensor 23 may output a third signal when the lever 13 is operated. In the actual fire extinguisher, the extinguishing agent is injected by operating the lever 13. In the virtual extinguisher of the virtual reality according to the embodiment of the present invention, when the third signal is inputted, the virtual extinguisher Can be injected.

The controller 30 may generate a virtual fire situation in which virtual fire is suppressed based on the second signal when the first and third signals are input and a virtual fire situation is generated in the virtual reality.

The background of the virtual reality can be retrieved from a database that is stored in advance, and can be selected. If the virtual reality is connected to the Internet online, new contents can be downloaded and selected on the Internet online.

The background of the virtual reality can be the interior of a general home such as a living room, a kitchen, a guest room, or the like, and can be stored in various backgrounds such as an industrial site, an office, a general store, a sightseeing spot, have.

And virtual fires can occur at different locations from where they occur each time they are new or just before. This allows the experimenter to experience a new fire situation, even if he or she is repeatedly trained in the use of firearms.

In addition, the second signal may be data generated when the nozzle is moved, and a direction in which the nozzles are collimated may be determined, and an image in which the extinguishing agent is sprayed by the third signal may be implemented. As a result, It is possible to generate an image in which a virtual fire is suppressed by synthesizing an image, a fire image, and an image in which a fire extinguishing agent is sprayed.

On the other hand, the various images may include a voice, and more specifically, the voice may be in a situation where the voice is displayed in the virtual reality. In addition, the sound may additionally be added with an effect sound. For example, sound may be accompanied by sound effects such as cracking of a window pane, screaming sound, and the like. This can add tension and dramatic effects to the fire scene generated within the virtual reality.

The communication unit 40 is connected to the outside of the fire extinguisher model 10 by wire or wireless, and data can be transmitted and received. More specifically, the communication unit 40 allows the control unit 30 to visually observe data of a final image generated from the outside. In addition, voice data included in the various images can be output through the communication unit 40. [

The communication standard used in the communication unit 40 uses a known communication standard, for example, a local area network using Bluetooth, and may be a wired communication in which a cable is directly connected. Also, the communication unit 40 may use a mobile communication network.

The data of the video and the voice outputted through the communication unit 40 are received outside the fire extinguisher model 10 so that it can be viewed by the participant or the lecturer who supervises the education or other participant participating in the education together. Can be displayed on the monitor.

Therefore, the training fire extinguisher of the virtual reality according to the embodiment of the present invention can realize a situation in which a fire occurs at an unexpected point and at an unexpected point, and the experient can find a fire extinguisher and secure a fire extinguisher Move to the fire point, remove the safety pin, aim the nozzle at the fire point, and grab the lever.

Meanwhile, according to the present invention, a fire is generated in a virtual reality, and a virtual extinguishing agent is sprayed, so that no physical extinguishing agent is sprayed. Thus, the training fire extinguisher of the virtual reality according to the embodiment of the present invention has an advantage that the environment for training the use of the fire extinguisher or training the fire extinguisher is not actually contaminated.

In addition, the training fire extinguisher of the virtual reality according to the embodiment of the present invention is advantageous in that it is convenient to clear the fire after completing the fire extinguisher usage tips and fire extinguishing exercises.

Meanwhile, the training fire extinguisher of the virtual reality according to the embodiment of the present invention may further include the fourth sensor 24 as shown in FIG.

The fourth sensor 24 may detect the posture and movement of the body 14 and output the fourth signal of the posture and movement of the body 14. [

When the first and third signals are input, the control unit 30 may generate a virtual extinguishing image in which the virtual fire is suppressed based on the second and fourth signals.

Thus, when the experimenter finds the digestive system, the attitude and position where the digestive system model 10 is placed is provided to the control unit 30, and when the experimenter moves with the digestive system model 10, Can be reflected. That is, the fourth sensor 24 can reflect the information (attitude and position) of the fire extinguisher model 10 within the virtual reality, so that the use of the fire extinguisher can be realized more realistically.

On the other hand, the training fire extinguisher of the virtual reality according to the embodiment of the present invention may further include the display device 50. [

The display unit 50 can be worn on the body of the user and can be worn, for example, as glasses. The virtual digestive image may be received by the display unit 50 through communication with the communication unit 40, and the virtual digestive image may be displayed to the experiencer as shown in FIG.

Therefore, when the user wears the display unit 50 and handles the fire extinguisher model 10 in accordance with the use of the fire extinguisher, the viewer can see the image reflected in real time in the display unit 50 have.

On the other hand, the training fire extinguisher of the virtual reality according to the embodiment of the present invention can output information on the viewer's gaze direction and the location of the experient in the display device 50 as experient information, The communication unit 40 can receive the experient information and transmit it to the control unit 30. [ The control unit 30 may generate the virtual extinguishing image based on the second signal and the experient information when the first and third signals are input.

Therefore, when the exercise fire extinguisher of the virtual reality according to the embodiment of the present invention takes a routine operation such as moving an experimenter and turning his or her head, such an operation is reflected on the virtual extinguished image, In real time.

On the other hand, the virtual fire extinguisher of the virtual reality according to the embodiment of the present invention detects the posture and the motion of the body 14 and outputs the posture and the motion of the body 14 to the fourth sensor And the control unit 30 may generate the virtual extinguishing image based on the second and fourth signals and the experient information when the first and third signals are input.

Thus, the training fire extinguisher of the virtual reality according to the embodiment of the present invention generates a virtual extinguished image by reflecting both moving the experient and moving the fire extinguisher model 10, Can be made larger.

In the training fire extinguisher of the virtual reality according to the embodiment of the present invention, a plurality of experients can experience fire extinguishing tips and fire extinguisher usage at a time. Hereinafter, an example in which a plurality of people experience the use of a fire extinguisher will be described with reference to FIG. 3 is a view for explaining an example in which a plurality of persons are trained together in a training fire extinguisher of a virtual reality according to an embodiment of the present invention.

The training fire extinguisher of the virtual reality according to the embodiment of the present invention may be provided with a plurality of display fishes 50 and a plurality of fire extinguisher models 10 may be provided. That is, one displayer 50 and one fire extinguisher model 10 may be provided per person.

And each of the displayer 50 and each fire extinguisher model 10 may be given a unique identification code.

In addition, information on the viewer's direction of the wearer wearing the display device and the position of the wearer wearing the display device can be output as a plurality of experience information for each of the plurality of display devices 50.

The communication unit 40 may transmit the plurality of experience information to the control unit 30 and the control unit 30 may receive the first and third signals based on the second signal and the plurality of experience information The virtual extinguishing image may be generated so that the virtual extinguishing image may be generated in a plurality of ways to match each experient information.

The communication unit 40 may transmit a plurality of virtual extinguishing images to the plurality of displayer 50, respectively, and may transmit the plurality of virtual extinguishing images to the corresponding displayer corresponding to the experient information.

As a result, several visitors can cooperate and experience fire suppression at the same time. More specifically, the first experient (U1) and the second experient (U2) can try to extinguish the fire aiming at the first fire point (60), and the third experient (Un) It is possible to attempt to extinguish the fire at the first fire point.

Further, a third experient (Un) may participate in the fire evolution of the first fire point (60) after performing fire suppression on the other second fire point (62).

That is, the training fire extinguisher of the virtual reality according to the embodiment of the present invention can realistically realize and experience a fire situation that can occur in reality when training a fire suppression.

On the other hand, the training fire extinguisher of the virtual reality according to the embodiment of the present invention may be provided with a plurality of the bodies 14 as described above. The body 14 may include a fourth sensor 24. The fourth sensor 24 may detect the posture and the motion of the plurality of bodies 14 and output the posture and the motion of the plurality of bodies 14 as a fifth signal.

When the first and third signals are input, the control unit 30 may generate a plurality of virtual digest images based on the second and fifth signals and the experient information.

Thus, when there are several experienced persons, it is possible to change the place among the participants in the process of fire suppression, and at this time, the virtual digestion image displayed to each individual may be different.

More specifically, as shown in FIG. 3, when the first experience user U1 and the second experience user U2 move while their physical positions are changed while trying to suppress the fire, Can be reflected and displayed on the image of the virtual reality.

Therefore, the training fire extinguisher of the virtual reality according to the embodiment of the present invention can perform the training for suppressing the fire that occurs at the same time by a plurality of experients, and in particular, when each experient is changing the position or changing the standing direction , The image seen by the subject can be remarkably improved by reflecting the shifted displacement or the gaze direction of the subject.

Hereinafter, the control unit 30 and the communication unit 40 of the training fire extinguisher of the virtual reality according to the embodiment of the present invention will be described with reference to FIG. 4 is a block diagram for explaining a training fire extinguisher of a virtual reality according to an embodiment of the present invention.

The training fire extinguisher of the virtual reality according to the embodiment of the present invention includes a control unit 30. The control unit 30 may include an input unit 32 and a processing unit 33. In addition, the controller 30 may further include a storage unit 31.

The processing unit 33 is connected to the communication unit 40 and can transmit and receive image data, voice data, and signals received from various sensors.

In the storage unit 31, data on 'virtual reality' and data on 'virtual fire' may be stored. More specifically, as data that can be a background of a virtual reality, various images such as a home, an office, and an industrial field may be provided, and each image may include audio data corresponding to the corresponding image.

In addition, the virtual fire may include information such as the size and location of the fire. In addition, the virtual fire may further include information such as whether it is a fire including oil, an explosive fire, a fire containing a toxic gas, and the like.

In this way, when implementing a virtual fire, you may experience whether the fire extinguisher is capable of extinguishing the fire or whether you need to find another kind of fire extinguisher.

That is, 'virtual reality' and 'virtual fire' are selected and recalled by the experient or the instructor who administers the training.

Safety pin information, nozzle information, lever information, fire extinguisher information, and experience information can be input to the input unit 32.

The safety pin information can determine whether or not the first signal generated by the first sensor 21 is generated by detecting whether the safety pin 11 is removed.

The nozzle information may be information on a displacement at which the nozzle 12 is moved. That is, based on the second signal generated by the second sensor 22, it is possible to know in which direction the nozzle is pointing and whether there is movement.

The lever information indicates whether the lever 13 is operated or not. On the other hand, if the experimenter does not remove the safety pin 11, the lever 13 can not be operated, so that the third signal is valid only after the first signal is generated.

The extinguisher information may be information about the direction of the fire extinguisher model 10 itself or the direction of the fire extinguisher model 10 itself. That is, the information on the posture and the position that occurs when the experimenter lifts the digestive system model 10 or moves with the digestive system model 10 can be output as the fourth signal by the fourth sensor 24. [

The experiential information may be data secured from the displayer 50 worn by the experient. More specifically, the gaze direction or the movement displacement (position displacement) of the experiencer, and the gaze direction and the position of the experient can be outputted from the displayer 50 as experient information. That is, if the experimenter moves while wearing the display unit 50, information on the movement and the gaze direction may be generated as experient information and provided to the controller 30 through the communication unit 40. [

The processing section 33 can synthesize an image after performing initialization. The initialization is to initialize the position and posture of the fire extinguisher in the virtual reality. For example, when the experient begins to experience, the attitude, position and direction of the fire extinguisher model 10 in reality can be matched with the posture, position and direction of the fire extinguisher in the virtual reality. Thus, when experiencing experiences of using fire extinguishers in virtual reality, it is possible to reduce the gap between reality and virtual reality, and furthermore, by making the reality and virtual reality coincide with each other, the experiencing person can avoid or minimize dizziness.

The synthesis of the image is a synthesis of a first image as a background of a virtual reality, a second image as a virtual fire, and a third image as an extinguishing agent is injected. In addition, the first, second, and third images have a voice corresponding to the image, so that a voice corresponding to the synthesized image can be output to the synthesized image.

On the other hand, in the synthesis of the image, the third image may be related to experient information and nozzle information. In other words, when the experimenter moves with the fire extinguisher model 10 or moves the nozzle 12, the background can be changed as the experimenter moves in the virtual reality, and in accordance with the movement of the nozzle 12, Direction can be changed. In addition, when the viewer's gaze is turned around, the viewer's gaze is reflected in the virtual reality, and the image can be changed in the virtual reality.

The output unit 40 can output the final image and voice synthesized and generated by the control unit 30. [ More specifically, an image may be output from a displayer provided outside the fire extinguisher model 10. At this time, if the display language supports the 3D image player, the 3D sensation can be felt for all objects in the virtual reality. For example, as shown in Fig. 2, the left eye image and the right eye image can be generated, respectively, and the experient can view the left eye image with the left eye and the right eye image with the right eye, The left eye image and the right eye image can be simultaneously recognized as a three-dimensional image having a three-dimensional effect.

Hereinafter, the operation of the training fire extinguisher of the virtual reality according to the embodiment of the present invention will be described with reference to FIG. 5 is a flowchart for explaining the operation of a training fire extinguisher of a virtual reality according to an embodiment of the present invention.

First, the experient or the instructor selects an image to be the background of the virtual reality and loads it (S10).

Then, various information can be inputted to the control unit 30 (S11). The input information may include "safety pin information", "nozzle information", "lever information", "fire extinguisher information", and "user information".

Meanwhile, the training fire extinguisher of the virtual reality according to the embodiment of the present invention is able to experience fire suppression by several people, so that there can be several experienced persons. Thus, in the case of a plurality of experience persons, the fire extinguisher model 10 and the display device 50 can be provided in the number corresponding to the number of the experience persons.

As described above, when a plurality of fire extinguisher models 10 and a plurality of displayer 50 are provided, a unique 'identification symbol' can be assigned to each participant, and the position of each fire extinguisher in the 'virtual reality' The posture can be initialized and an output signal to be associated with each fire extinguisher model 10 can be initialized (S12).

In other words, if there are three experienced users, the first experiencer U1 will wear the first fire extinguisher model and the first displayer. Likewise, the second experient (U2) will wear the second fire extinguisher model and the second displayer, and the third experient (Un) will wear the third fire extinguisher model and the third displayer.

As described above, when the position and posture of each fire extinguisher is initialized in the virtual reality, the gaze of the first experiencer U1 is reflected on the image to be displayed on the first displayer. Likewise, the line of sight of the second experiener U2 may be reflected on the image to be displayed on the second displayer, and the line of sight of the third experienent Un may be reflected on the image to be displayed on the third displayer. That is, each participant can receive a video suitable for his or her own gaze.

Further, when there are a plurality of fire extinguisher models, one of them may serve as a server and the other fire extinguisher model may serve as a client. That is, the control unit 30 of the fire extinguisher model serving as a server can control the control unit 30 of the remaining fire extinguisher model. In addition, the server role fire extinguisher model 10 collects data from the fire extinguisher model 10 of the client role. The data may be the information input described in step S11. Then, the control unit 30 of the server role synthesizes and outputs video and audio corresponding to the situation of each experient, so that each experient can contact the video and audio suitable for his / her situation.

As described above, the 'virtual fire' image may be synthesized in 'virtual reality' to output an image (S13). At this time, a fire warning sound may be output. The fire alarm sound may be understood as a preparation signal for the user to secure a fire extinguisher.

The experimenter recognizes that a fire occurs in the virtual reality and finds a fire extinguisher. In reality, the fire extinguisher model 10 is secured. In the virtual reality, the process of finding the fire extinguisher and the process of securing the fire extinguisher can be displayed.

The experimenter removes the safety pin 11 in accordance with the use of the fire extinguisher. The control unit 30 determines that the safety pin has been removed when the first signal indicating that the safety pin 11 has been removed is input (S14).

The experimenter moves the nozzle 12 and grips the lever 13 after the safety pin 11 is removed. At this time, the nozzle information is generated according to the movement of the nozzle 12, so that the nozzle moves in the virtual reality, and as the experimenter moves the nozzle 12 toward the fire point, the nozzle aims at the fire point in the virtual reality (S15). In addition, the experimenter operates the lever 13 to output an image in which the extinguishing agent is sprayed in the virtual reality (S15).

In the virtual reality, a 'virtual fire' image and a 'fire extinguisher injection' image are synthesized to output a 'virtual fire' image (S16).

On the other hand, it is judged whether or not the digestion condition is satisfied (S17). Here, the digestion condition is to judge how much the extinguishing agent is sprayed to the fire point and for a predetermined time. In other words, when the fire is suppressed in reality, even if the fire extinguishing agent reaches the flame, it is not immediately extinguished, but reflects the fact that it is extinguished when the fire extinguishing agent is properly sprayed.

If the fire extinguishing condition is satisfied, the area in which the 'fire extinguishing condition' is satisfied in the 'virtual fire' image is erased and the 'virtual fire' image is renewed and output (S18). That is, as the digestion progresses, the size of the flame decreases, reflecting the gradual extinguishment of the flame in the virtual reality.

Then, it is determined that the 'virtual fire' image is deleted in the virtual reality (S19). If there is a 'virtual fire' image, it can be understood that the fire suppression is not completed. However, it can be understood that the fire suppression is completed when the 'virtual fire' image gradually disappears and disappears completely.

When the 'virtual fire' image is erased in the virtual reality as described above, a message indicating 'complete fire extinguishing' is outputted and the process is terminated (S20).

As described above, the training fire extinguisher of the virtual reality according to the embodiment of the present invention can experience that the experiencer obtains the fire extinguisher model 10 in the real world and performs the fire suppression in the virtual reality. Particularly, the experiential person can experience experience in virtual reality, including the process of recognizing the fact that a fire has occurred and moving to a fire site before actually extinguishing the fire in a virtual reality. You can learn.

Particularly, the training fire extinguisher of the virtual reality according to the embodiment of the present invention does not have a large screen or a large monitor for projecting the image before, which is advantageous in that the constituent elements are simplified.

The training fire extinguisher of the virtual reality according to the embodiment of the present invention includes the control unit 30 and the communication unit 40 in the body 14 of the fire extinguisher model 10 so that the server computer, There is an advantage to be able to.

In addition, the training fire extinguisher of the virtual reality according to the embodiment of the present invention may have a plurality of places where a fire occurs, such as an actual fire scene, and may be a plurality of people participating in the training. That is, the training fire extinguisher of the virtual reality according to the embodiment of the present invention can suppress the fire generated at various points in the virtual reality, and can suppress the same fire point in cooperation with the peer.

Meanwhile, the training fire extinguisher of the virtual reality according to the embodiment of the present invention does not have a particular limitation on such movement when a plurality of experters move at the same time, so that, for example, It is possible to move to a more convenient copper line.

That is, the training fire extinguisher of the virtual reality according to the embodiment of the present invention can realize the fire situation very similar to the actual situation as compared with the fire extinguisher for training purpose or training purpose known in the art, Fire drills can be conducted.

Therefore, the training fire extinguisher of the virtual reality according to the embodiment of the present invention can make an impression stronger to the user when training the use of fire extinguishers or training the fire extinguisher, thereby remarkably improving the educational effect.
