Next, in the step (S120) of the user terminal accessing the control room server to request a disaster occurrence reception and transmitting location information, the user terminal is connected to and connected to the control room server through an account registered in the system through the information and communications network, S110 The location information generated in step is transmitted to the control room server. The location information transmission in step S120 may be performed in real time.

Next, as a step (S130) of the situation room server registering the received building and disaster area as a disaster site, the situation room server determines the disaster place according to the location information provided from the user terminal and sets the place as a disaster site in the system. In the step (S140) of registering and determining the current location of the user terminal for each floor through the location information transmitted from the user terminal located in the building where the situation room server is registered as a disaster site, based on the location information for each user collected in step S120 Thus, the current location of the user is determined.

In this case, the user may be located in a building having two or more floors, and the control room server may determine on which floor the user is located by referring to the building drawings for each floor of each building registered in the database. In particular, when determining the location of the user in the building, the beacon signal coordinates included in the location information may be utilized.

Next, the situation room server matches the determined current location of each user terminal with the building drawing for each floor, and connects the current location and the emergency exits and building exits included in the building drawing to the shortest distance to avoid the disaster area to create an evacuation route In step S150, the situation room server extracts the building drawings for each floor of the building registered with the disaster with reference to the database, and maps the current location of the user to the building drawings of the corresponding floor. In addition, the situation room server creates an evacuation route by connecting the current location of the user and each escape section on the building drawing to which the location of the user is mapped with the shortest distance.

Next, in the step (S160) of the situation room server transmitting the evacuation information including the evacuation route to the user terminal, the evacuation information including the evacuation route in which the current location of the user matched on the building drawing is displayed is transmitted in real time through the information and communication network. transmitted to the user terminal. In addition, the situation room server may request assistance or dispatch by transmitting the current location of a user who has not yet evacuated to other user terminals belonging to the same group as the user terminal and to a rescuer terminal located in an adjacent place.

The above-described steps S140 to S160 may be repeatedly performed by updating the user's current location in real time until the user reaches the exit, and the situation room server determines that the user has reached the exit, causing a disaster for the corresponding application. You can end the situation.

In particular, in one embodiment of the present invention, the main screen may provide a UI for executing a main function with a single touch, and such UIs include "check evacuation route (W110)" and "call to control room (W120)" " and "Transmit my location (W130)" and the like.

The function of checking the evacuation route (W110) is a function of displaying evacuation information provided by the control room on the screen according to selection. As the user terminal 100 transmits the currently generated location information to the control room server, the control room server is If the current location is mapped on the drawing and an evacuation route is created, it can be received and displayed on the screen.

The call to the situation room (W120) function is a function to directly connect a call to the situation room phone provided in the situation room according to selection by referring to one or more situation room phone numbers preset in the disaster evacuation application.

In addition to the function of requesting the evacuation information described above by immediately transmitting the current location information generated using the location signal to the control room, the function to transmit my location (W130) provides the location of the current user, that is, the evacuee, to the rescuer terminal through the control room. It is a function that allows you to transmit.

Referring to FIG. 6 , in an embodiment of the present invention, the user terminal 100 may transmit current location information to the control room server, receive evacuation information including an evacuation route from the control room server, and display it on the screen.

The evacuation route included in the evacuation information may be generated based on the building drawings for each floor of the buildings constructed in the control room server, and the building drawings of the evacuation route screen W200 display rooms, stairs and passages, etc. Locations of facilities available in case of emergency, such as fire hydrants, fire extinguishers and defibrillators, may be displayed.
