Description

TECHNICAL FIELD The present invention relates to a method and system for providing a location of a collaborative firefighter using wireless communication, a method for displaying a location of a cooperative firefighter, and a fire helmet for performing the same. BACKGROUND OF THE INVENTION A POSITION OF CO-OPERATED FIREFIGHTER, AND FIRE HAT FOR PERFORMING THE METHOD}

The present invention relates to a method and system for providing a location of a collaborative firefighter using wireless communication, a method for displaying the position of a collaborative firefighter and a firefighting helmet for performing the same, and more particularly, In this paper, we propose a method of providing location of collaborative firefighters using wireless communication to maximize efficiency of firefighting collaboration and to maximize safety accident prevention efficiency by marking on goggles of firefighting helmets to real time moving positions of collaborating firefighters. And a fire helmet for performing the method.

In general, there are disaster response agencies in each area to deal with disasters such as natural disasters or fires immediately. Disaster response organizations include, for example, police stations, military units, fire stations, service organizations, and various related organizations.

When a disaster response is received by a disaster response agency within the disaster area, the disaster response agency dispatches disaster response personnel with disaster response equipment to the disaster site. In order for disaster response personnel to respond effectively to the disaster, the commander at the disaster site directs the disaster response personnel to work. Disaster response personnel rescue people at the scene of the disaster according to the direction of the conductor and rectify the scene.

However, in the past, the commander of the disaster relied on his / her sense of hearing and memory to direct and control the activities of disaster response personnel. Therefore, safety incidents such as injuries, Of cases occurred frequently. In this case, due to the inadequate management system of on-site personnel, there is a case where the dismissal of the personnel is not recognized even until the disaster situation ends. Therefore, there is an urgent need for a systematic management of disaster response personnel.

On the other hand, it is very important to develop, maintain and repair disaster response equipment in order for disaster response personnel to respond quickly to disasters in the field of fire.

With this in mind, various indoor and outdoor emergency rescue personnel location tracking systems have been developed. For example, an indoor positioning map matching technique that measures the position of a user using a WiFi access point installed in a building in a indoor / outdoor navigation system has been developed. The Wi-Fi access point measures the location of the user in the building by recognizing the signal strength of the surrounding Wi-Fi access point received in the navigation system by the terminal installed in the building for the communication service providers to provide the Wi-Fi. This technology makes it possible to utilize a Wi-Fi access point because basic navigation using a navigation device can not be used as an indoor navigation due to difficult GPS reception in the building.

However, the location tracking system can become useless if the Wi-Fi access point installed inside the building does not operate normally due to lack of management or can not operate normally due to fire.

Also, in order to suppress the fire and rescue people more quickly in a fire building, a clearer recognition of the interior of the building is required. However, in the urgent situation of fire, it is not possible to grasp the structure inside the building clearly and reach the fire point and suppress the fire.

The virtual object may be displayed on the goggle member in such a manner that two images are superimposed on the object existing in the real world beyond the goggle member. The location information of the fire helmet 100 may be transmitted to the control center 300 by location information of the fire helmet 100 corresponding to the fire helmet 100 corresponding to the client. The traveling path of the wearing helmet 100 can also be automatically stored.

Here, the controller 200 may be a fire truck positioned in the vicinity of the fire helmet 100. The controller 200 is connected to a remote control center 300 through a wireless communication connection and transmits information on the site conditions to the control center 300 and receives various information of interest from the control center 300 . Internal information of the fire building located near the point where the controller 200 is located can be transmitted from the control center 300. For example, if the fire helmet 100 is present in a specific area of the fifth floor in a multi-layered building, the 3D map information corresponding to the five layers may be extracted and provided to the fire helmet 100 . In the fire helmet 100 provided with the 3D map information, the information of the firefighter's viewing angle and the azimuth angle is used, and the inside of each building of the fifth floor is observed by the method of applying the augmented reality technique. Images are superimposed and displayed.

In addition, when the fire helmet 100 requests a viewing request of a cooperative firefighter, the location information of the cooperative firefighter is requested to the controller 200 and the positional information of the received cooperative firefighter is transmitted to the goggles of the firefighter helmet 100 .

The fire fighting helmet 100 according to the present invention is applied to the fire helmet 100 by applying the augmented reality technique that realizes a virtual reality in which a user views the real world viewed by the user and a virtual world having additional information together as one image Outline lines of various walls and doors in a building can be superimposed and displayed in a virtual object form on the actual image viewed by a firefighter.

3D map information corresponding to the position information of the specific fire helmet is extracted and provided to the corresponding fire helmet (step S330). For example, when a fire helmet exists in a specific area of the fifth floor in a building having a plurality of layers, 3D map information corresponding to the five layers may be extracted and provided to the fire helmet. In the fire helmet provided with the 3D map information, the virtual image is overlapped with the actual image in the goggle member so that the interior of each building on the fifth floor can be observed by using the augmented reality technique by using the information such as the angle of view and the azimuth angle of the firefighter .

Then, whether or not biometric information is received is checked (step S340). The biometric information can be received by the receiving unit 310 shown in FIG. 3, and the system control unit 350 shown in FIG. 3 can check whether the biometric information is received or not.

If it is checked in step S340 that the biometric information is received, the biometric information for each fire fighting helmet, that is, the firefighter is stored (step S350). The biometric information for each firefighter can be stored in the biometric information storage unit 370 by the system control unit 350 shown in FIG.

After storing the biometric information for each firefighter or checking that the biometric information is not received in step S340, the end of the fire suppression is checked (step S360). A check as to whether or not the fire suppression is completed can be made by the system control unit 350 shown in FIG.

If the end of the fire suppression is checked in step S360, the process is terminated. If the end of the fire suppression is not checked, the process returns to step S310.

7 is a flowchart illustrating a method of displaying a location of a cooperative firefighter using wireless communication according to another embodiment of the present invention. In particular, the present invention is a flow chart for explaining an operation performed in a fire helmet having a position display function of a collaborative firefighter using wireless communication.

Referring to FIG. 7, the helmet control unit 140 checks whether the power of the special purpose helmet is turned on (step S410). The power supply can be turned on through a separate operation button or the like.

If it is checked in step S410 that the power is turned on, the helmet control unit 140 detects the current position of the firefighter wearing the fire helmet (step S412). The detection of the current position may be performed through the current position detection sensor 125. [

Next, the helmet control unit 140 requests the controller for 3D map information corresponding to the current position (step S414). The 3D map information may be requested through the wireless communication port 160.

The helmet control unit 140 checks whether 3D map information is received at the controller (step S416).

If it is determined in step S416 that the 3D map information is received in the controller, the helmet control unit 140 displays the image corresponding to the current position on the goggles member (step S418).

Next, the helmet control unit 140 detects the moving distance, the azimuth angle, and the viewing angle on the 3D image (step S420). Detection of the moving distance, the azimuth angle, and the viewing angle on the 3D can be performed through the 3D acceleration sensor 130. [

The helmet control unit 140 controls the head mount projector 150 to display an image on the goggles member 120 based on the moving distance, the azimuth angle, and the viewing angle (step S422).

The helmet control unit 140 checks whether image viewing of the cooperative firefighting apparatus is requested (step S424). The image viewing request of the collaborative firefighter can be made through a separate operation button or the like.

If it is determined in step S424 that the image viewing of the collaborative firefighter is not requested, the flow returns to step S420.

If it is checked in step S424 that the image viewing of the collaborative firefighter is requested, the helmet control unit 140 requests the cooperative firefighter to locate the cooperative firefighter corresponding to the current location (step S426). The location request of the cooperative firefighter may be made through the wireless communication port 160.

Next, the helmet control unit 140 checks whether the position information of the collaborative firefighter is received from the fire helmet worn by the cooperative firefighter (step S428). The location information of the cooperative firefighters may be transmitted through the wireless communication port 160.

If it is checked in step S428 that the location information of the collaborative firefighter is received, the helmet control unit 140 controls the head-mounted projector 150 to display the position of the cooperative firefighter on the goggle member 120 (step S4230) .

Next, the helmet control unit 140 checks whether power is off (step S432). The power off may be performed through a separate operation button or the like.

If it is checked that the power is off in step S432, the helmet control unit 140 checks whether switching to the previous mode is requested (step S434). In the present embodiment, the previous mode may mean a mode in which the position information of the collaborative firefighter is displayed.

If it is determined in step S434 that the switch to the previous mode is not requested, the flow returns to step S420.

On the other hand, if it is checked in step S434 that the switching to the previous mode is requested, the flow returns to step S430.
