5 is a flowchart illustrating a virtual reality-based fire response training method according to an embodiment of the present invention. In the illustrated flowchart, the method is described as being divided into a plurality of steps, but at least some of the steps may be performed in sequence, combined with other steps, performed together, omitted, divided into sub-steps, One or more steps may be added and performed. Also, one or more steps not shown in the method according to the embodiment may be performed with the method.

Referring to FIG. 5, the mobile terminal 104 confirms whether a training start signal is input (S 101). The training start signal may be input from a training participant having the mobile terminal 104. For example, an application for a virtual reality-based fire response training may be installed in the mobile terminal 104. When the training participant executes the application, the application can provide an interface for receiving training instructing instruction of the training participant. In this example, the training start signal is inputted from the training participant, but the training start signal is not limited to this, and the training start signal may be input from the management server 112. [

If it is determined in step S 101 that a training start signal is input, the mobile terminal 104 acquires an image data set for generating a virtual reality fire image (S 103). The mobile terminal 104 may acquire an image data set from the image storage 135 within the mobile terminal 104, but not limited thereto. In addition, the mobile terminal 104 may acquire a corresponding set of image data according to the incoming fire environment set information.

Next, the mobile terminal 104 can transmit the generated virtual reality fire image to the display device 106 (S 109). The display device 106 can project the virtual reality fire image forward and display it.

Next, the mobile terminal 104 confirms whether at least one of the position information, attitude information, and direction information of the training participant is changed (S 111). After training begins, the trainee will act according to the corresponding manual, so the location information, attitude information, and direction information of the trainee can be changed from time to time.

If at least one of the position information, the attitude information, and the direction information of the training participant is changed as a result of the check in step S111, the mobile terminal 104 extracts another virtual image corresponding to the changed information of the training participant, , And updates the virtual reality fire image using another extracted virtual image (S 113). The mobile terminal 104 transmits the updated virtual reality fire image to the display device 106. In this case, the virtual reality fire image is displayed in synchronization with the position, posture, and direction of the training participant.

Next, the mobile terminal 104 confirms whether the fire extinguisher attitude information and fire extinguisher injection information are transmitted from the training fire extinguisher 110 (S 115). The training participant can search for the training fire extinguisher 110 provided in the experience room 102 and can use the fire extinguisher 110 to suppress the fire in the virtual reality. The training participant can remove the safety pin 161 and grasp the manipulation part 147 with one hand and grasp the injection hose 145 with the other hand and apply the pressure to the manipulation part 147 to initiate the extinguishing agent injection action . Then, the training fire extinguisher 110 may generate fire extinguisher attitude information and fire extinguisher injection information, and may transmit the information to the mobile terminal 104.

If it is determined in step S 115 that the fire extinguisher attitude information and fire extinguisher injection information are transmitted from the training fire extinguisher 110, the mobile terminal 104 checks the fire extinguisher state of the fire extinguisher using the fire extinguisher attitude information and fire extinguisher injection information And generates fire suppression state information (S 117).

Next, the mobile terminal 104 updates the virtual reality fire image according to the generated fire suppression state information (S 119). That is, the mobile terminal 104 updates the fire-related image in the virtual reality fire image according to the generated fire suppression state information, so that the fire suppression degree according to the fire suppression state of the training participant can be reflected in the virtual reality fire image.

Next, the mobile terminal 104 transmits monitoring information on the fire response status of the training participant to the management server 112 (S 121). That is, the mobile terminal 104 may generate monitoring information by monitoring a fire correspondence situation of a training participant from the start of the training. The mobile terminal 104 may send monitoring information to the management server 112 after the training is complete. However, it is not so limited, and the mobile terminal 104 may transmit monitoring information to the management server 112 even during training.

Next, the mobile terminal 104 receives training result information from the management server 112 (S 123). The mobile terminal 104 may display the received training result information on the screen through the display unit 127. [ The training result information may include at least one of training evaluation information of the training participant, misreporting information of the training participant, and training order information of the corresponding training participant.
