In particular, when the display unit 130 is formed of a touch screen, some or all of the functions of the input unit 120 may be performed through the display unit 130 .

The storage unit 140 serves to store programs and data necessary for the operation of the control device 100 . For example, the storage unit 140 may store an application for specifying an area difficult to pass due to a fire as a danger area by collecting various information, an application for calculating a shortest route evacuation route while bypassing the danger area, and the like. In addition, the storage unit 140 is a voice instructing the user to receive the location information where the router 200 is installed, the location information where the fire alarm 300 is installed, and the fire information through the router 200 according to the embodiment of the present invention.

The controller 150 may control the overall operation of the control device 100 and the signal flow between internal blocks of the control device 100 , and may perform a data processing function of processing data. The control unit 150 may be a central processing unit (CPU), a digital signal processor (DSP), or the like. The operation of the control unit 150 will be described in more detail below.

Next, a method for fire evacuation guidance using a wireless router and Wi-Fi according to an embodiment of the present invention will be described. 3 is a flowchart illustrating a method for fire evacuation guidance using a wireless router and Wi-Fi according to an embodiment of the present invention. 4 is a view for explaining a method of deriving an evacuation route according to the danger area according to an embodiment of the present invention. 5 is an example of a screen for displaying information on people on each floor in a building on a screen according to an embodiment of the present invention.

Referring to FIG. 5 , it is assumed that the control unit 150 of the control device 100 is in the normal mode in step S100 . In the normal mode, the user device 400 may request a network connection through the router 200 . Accordingly, when receiving an access request from the user device 400 through the communication unit 110 , the control unit 150 provides the user device 400 with a captive portal page including an interface for authentication. These subordinate portal pages may further include advertisements or other notification contents. The user device 400 may be connected to the network through login in the subordinate portal page.

Meanwhile, the control unit 150 monitors the plurality of fire detectors 300 in step S120 to determine whether a fire has occurred. As a result of the check, if there is no fire, the peacetime mode of step S100 is maintained.

On the other hand, as a result of the check, when a fire signal is received from the at least one fire detector 300 , the control unit 150 confirms that a fire has occurred, and sends the information to the user device 400 connected to the router 200 in step S130 . Switch to disaster mode, a state that can provide fire information. To this end, the controller 150 transmits a mode change message to the router 200 so that the router 200 switches from the normal mode to the disaster mode. Accordingly, the router 200 is switched to the disaster mode.

After switching to the disaster mode in step S130, the controller 150 instructs the router 200 to receive the fire information through the router 200 so that the user device 400 around the router 200 receives the fire information through the router 200 in step S140. A voice message is transmitted to the router 200 through the communication unit 110 to output the message. Accordingly, the router 200 continuously outputs a voice message through the provided speaker. For example, the voice message can be something like "There is a fire. You can find out about the fire situation through a Wi-Fi connection."

On the other hand, after switching to the disaster mode in step S130, the control unit 150 provides a floor-by-floor building guide map to the user device 400 connected to the router 200 via the router 200 via the communication unit 100 in step S150. send. Accordingly, the user device 400 connected to the router 200 can display a building guide map for each floor on the screen. In particular, the guide map for each floor displays a building guide map of the floor where the router 400 is installed as a start screen. Moreover, the building guide map for each floor may display an area in which the fire detector 300 that transmits the fire occurrence signal for the first time is located.

In addition, after switching to the disaster mode in step S130 , the controller 150 collects temperature information for each router 200 at a predetermined period in step S160 . This temperature information includes temperature information indicating the temperature measured by the router 200 . Here, the temperature information may be at least one of a CPU (Central Processing Unit) temperature of the router 200 and a temperature measured through a temperature sensor provided in the router 200 . This temperature information serves as a survival signal indicating that the router 200 is operating.

Next, the control unit 150 derives a dangerous area based on the temperature information in step S170. First, the control unit 150 sets a danger area with a predetermined radius from the location where the fire started. And the control unit 150 sets a predetermined radius from the location where the router 200 that does not transmit temperature information for more than a preset time (eg, two cycles) is installed as a dangerous area. In addition, the control unit 150 sets a predetermined radius as a dangerous area at a location where the router 200 is installed, where the temperature measured among the plurality of routers 200 is equal to or higher than a preset temperature according to the temperature information. For example, referring to FIG. 4 , it is assumed that the first area A1 is an area where a fire started. In addition, in the second area A2, the router 200 located in the second area A2 does not transmit temperature information for more than a preset time (eg, 2 cycles), or the router 200 located in the second area A2 ) according to the transmitted temperature information, it is assumed that the temperature measured by the router 200 is equal to or greater than a preset temperature. Then, the controller 150 may set the first area A1 and the second area A2 as dangerous areas.

Then, the control unit 150 transmits the location information of the danger area to the user device 400 connected to the router 200 through the communication unit 110 in step S180 . Accordingly, according to an embodiment, the user device 400 may display the danger area on the previously received building guide map. For example, as shown in FIG. 4 , the user device 400 may display the first and second areas A1 and A2 as danger areas in the building guide map. Also, the user device 400 may warn the user not to approach the danger area.

According to another embodiment, in the user device 400 used by a user residing in a corresponding building, an app for generating an evacuation route may be pre-installed. Such an app may be downloaded from the control device 100 and installed in advance. As such, when an app for generating an evacuation route is installed in the user device 400, the user device 400 determines the current location ( CL) to create an evacuation route (EP) that can be evacuated by avoiding the danger area, and as shown in FIG. 4 , the danger areas (A1, A2) and the evacuation route (EP) are displayed on the previously received building guide map can do.

On the other hand, in the case of the user device 400 used by the user visiting the building, downloading and installing an app that generates an evacuation route is not time-consuming. For this case, the controller 150 assumes that the user's current location is the location of the router 200 to which the user device 400 is connected, and in step S190 evacuates from the location where each of the plurality of routers 200 is installed. For this purpose, it is possible to create an evacuation route that bypasses the danger area from the preset default evacuation route. The control unit 150, for example, as shown in FIG. 4, sets the basic evacuation route DP from the location IL where each of the plurality of routers 200 is installed for each router 200 in advance, and sets the default evacuation route ( DP) is stored in the storage unit 140 . And the control unit 150 derives an evacuation path EP that bypasses the danger areas A1 and A2 calculated earlier (S170) from the preset basic evacuation path DP in a fire situation.

Then, in step S200, the control unit 150 through the communication unit 110 through the communication unit 110 for each router 200, each of the plurality of routers 200 from the installed location (IL) to bypass the danger areas (A1, A2) evacuation route (EP) is transmitted to the user device 400 connected to the router 200 . Accordingly, the user device 400 connected to the router 200 displays the evacuation route EP bypassing the danger areas A1 and A2 from the location IL where each of the plurality of routers 200 is installed on the screen. can do. At this time, as shown in FIG. 4 , the user device 400 may display the corresponding evacuation route EP on the previously received building guide map for each floor.

And after switching to the disaster mode in step S130, the controller 150 logs the plurality of user devices 400 accessing each of the plurality of routers 200 from the plurality of routers 200 in a predetermined time unit in step S210. The record is received, and the received log record is divided for each router 200 and stored in the storage unit 140 .

And, the control unit 150 assumes that the location of the user who is the rescued is the location of the router 200 to which the user device 400 is connected, and displays the display unit 130 according to the log record stored in the storage unit 140 in step S220. Through this, the number of users corresponding to the location of the router 200 may be displayed on the building guide map. The number of users corresponding to the location of the router 200 is displayed by floor 51, and the last time the log record was received, that is, the update time 53 may be displayed together. Accordingly, the manager and rescue personnel of the control device 100 may check the location of the rescued person through the screen displayed on the display unit 130 .

Meanwhile, the method according to the embodiment of the present invention described above may be implemented in the form of a program readable by various computer means and recorded in a computer readable recording medium. Here, the recording medium may include a program command, a data file, a data structure, etc. alone or in combination. The program instructions recorded on the recording medium may be specially designed and configured for the present invention, or may be known and available to those skilled in the art of computer software. For example, the recording medium includes magnetic media such as hard disks, floppy disks and magnetic tapes, optical recording media such as CD-ROMs and DVDs, and magneto-optical media such as floppy disks ( magneto-optical media), and hardware devices specially configured to store and execute program instructions, such as ROM, RAM, flash memory, and the like. Examples of program instructions may include not only machine language wires such as those generated by a compiler, but also high-level language wires that can be executed by a computer using an interpreter or the like. Such hardware devices may be configured to operate as one or more software modules to perform the operations of the present invention, and vice versa.
