The ID storage unit 110 may store a unique identification number of the NFC tag 100. The location information storage unit 130 may store location information corresponding to the unique identification number. For example, suppose that 100 NFC tags 100 are attached or installed to each floor in a structure. The first floor may be assigned a unique identification number 1001, 1002, and the like, and the location information of 1001 may be, for example, GPS information of a location to which 1001 is attached or a preset code within a structure. In this case, the unique identification number of the ID storage unit 110 and the location information of the location information storage unit 130 may be matched and stored.

The emergency evacuation route storage unit 150 may store data on an optimal evacuation route corresponding to at least one exit based on the location information. For example, assuming that the location where the NFC tag 100 is attached is the 3rd basement floor and there are 8 passages based on the current position, the route that can be evacuated to the fastest and safest of the 8 passages can be stored. have. The data on the optimal evacuation route stored in the emergency evacuation path storage unit 150 may vary for each position where the NFC tag 100 is attached.

Emergency evacuation storage unit 150 is based on the location information, the direction and distance to the selected one of the at least one exit, the direction and distance to the next NFC tag 100, NFC tag 100 is attached At least one of the structural diagram and emergency evacuation guidance information of the structure may be stored.

For example, assuming that the NFC tag 100 is attached to an intermediate point between lines 4 and 7 of the Isu station, the exit may be at least 12 and at most 14 based on the corresponding location information. Each exit is adjacent, like Isu Station, and you have to go down and go up again to get out. If you have a clear view, you can go out to any exit. The user may be confused about it.

In this case, the optimal exit is selected in consideration of various criteria such as moving distance and safety in case of emergency based on the point where the NFC tag 100 is attached among at least 12 exits, and the user can use the direction and distance to the optimum exit. You should be able to let them know.

In addition, if too far to the exit, the user may go wrong in the other direction, so should be able to tell the direction and distance to the next NFC tag 100 located to go to the optimum exit. In addition, if only the direction and distance to tell, confusion may come, at least one of the structural diagram, emergency evacuation guidance information of the structure to which the NFC tag 100 is attached.

Accordingly, the NFC tag 100 may store information to be notified to the user in the emergency evacuation storage 150. This is pre-stored data based on the point where the NFC tag 100 is attached or installed.

Referring to FIG. 4, the NFC tag 100 may further include a light emitting device 110 on the outer circumference of the NFC tag 100. The light emitting device 110 may be an LED and may be driven by a power source separate from the power source of the structure. Therefore, even when the structure is in a state where power is not cut off in an emergency, the corresponding light emitting device 110 may be driven to irradiate light with the NFC tag 100 and may serve as an induction lamp in an emergency.

For example, when the light source 110 emits light in a state where power is cut off and the view is not secured, people naturally gather to a place where light is present, and the NFC tag 100 can be viewed. In this case, the likelihood of the user tagging the NFC tag 100 may be increased, and the casualty may be minimized by providing an optimal path for emergency escape guidance.

The light emitting device 110 may be arranged to be spaced apart at regular intervals on the outer periphery of the NFC tag 100, may be disposed continuously along the outer periphery without spaced apart, it may be to emit light from the back in the form of a backlight. If the NFC tag 100 can emit light even when the power of the structure is cut off, the kind or arrangement of the light emitting device 110 is not limited to a particular kind or arrangement.

Referring to FIG. 5, the NFC tag 100 may be attached to the emergency door induction lamp. That is, the induction indicator is prescribed by fire, and is driven separately from the power source of the structure, and is arranged in a certain place. That is, the induction light is always driven by alternative power even when the power supply of the structure is cut off, so that when the NFC tag 100 is attached to the induction light, even if there is no separate light emitting device 110, even in the event of an emergency in the eyes of the user Can be.

Alternatively, the NFC tag 100 itself may be formed of a luminous material. It may be a luminous material that absorbs light when there is light and irradiates light when there is no light. The outer periphery of the NFC tag 100 itself may be formed of a luminous material. Alternatively, it may be treated with a luminous material. Alternatively, the luminous material sticker may be attached.

The recognition unit 310 may recognize the NFC tag 100. The storage unit 320 may store data input from the recognition unit 310. For example, the storage 320 may store one or more data of the NFC tag 100 input from the recognition unit 310.

The controller 330 may control to output an optimal evacuation path corresponding to at least one exit based on the data. The controller 330 may control to determine and output the suitability of the movement path of the user according to the recognition order of the NFC tag 100. In addition, the controller 330 may control to output an alarm for the movement path failure when the optimal evacuation path direction and the recognition order of the NFC tag 100 are reversed.

For example, based on the NFC tag 100 tagged by the user at the current location, the NFC tag 100, the NFC tag 2, 100, and the NFC tag 100 in order to go to the optimal Let's assume that the path is the right path to the right. However, when the user is embarrassed in an emergency situation and does not distinguish the left side of the right side, people are swept away as they flock, and then accidentally finds the NFC tag 100 that is found in 9 times, the control unit 330 is the NFC tag 100 times. Is not tagged, you can sound the alarm. In addition, the controller 330 may control to output the optimum evacuation path direction and the exit again based on the NFC tag 100 in this case.

In addition, after the NFC tag 100 is recognized, the control unit 330 recognizes a different NFC tag from the NFC tag 100, and a path of movement from the NFC tag to another NFC tag and another NFC tag 100. It is possible to control the output of the optimum evacuation route as the starting point in different colors. For example, a user may not be able to keep track of where he or she came from. In this case, the movement path that the user moves in the structure diagram of the structure is displayed using the order of tagging the NFC tag 100, and the optimal evacuation path based on the NFC tag 100 is outputted in a different color. For example, you can distinguish between paths that pass through and paths that pass through.

In addition, the controller 330 may control to display an arrow on the screen for the optimal evacuation path on the structure diagram of the structure. The controller 330 may display any one of a structure diagram and an emergency evacuation guide map of the structure to which the NFC tag 100 is attached, and an arrow corresponding to an optimal evacuation route on the structural diagram and emergency evacuation guide map, and a direction. At least one of the distances may overlap.

The display 340 may output an optimal evacuation path on the screen under the control of the controller 330. The disaster point receiver 350 and the rescue requester 360 will be described with reference to FIG. 9.

FIG. 7 is a view for explaining an embodiment of the emergency evacuation guide apparatus of FIG. 6, and FIG. 8 is a view for explaining an embodiment of the emergency evacuation guide apparatus of FIG. 6.

Referring to FIG. 7, the emergency evacuation route guide apparatus 300 shows a screen displaying the unique identification number of the current location and the optimal emergency evacuation route.
