Abstract

A fire alarm apparatus interworking with a mobile terminal comprises a plurality of wireless Access Points (APs) provided in a building, the plurality of wireless APs wirelessly accessing a mobile terminal entering the building to receive a phone number from the mobile terminal, a fire alarm receiving the phone number from the wireless APs to register the mobile terminal as a target terminal, transmitting positions of the wireless APs in the building and an electronic map of an inside of the building to the target terminal through the wireless APs, and when sensing a fire, transmitting a position of the fire and an alert message to the target terminal, and the mobile terminal receiving and storing the positions of the wireless APs and the electronic map, and when receiving the alert message, outputting a map image and a voice message for guiding to an exit.

Claims

1. A fire alarm apparatus interworking with a mobile terminal, the fire alarm apparatus comprising:

a plurality of wireless Access Points (APs) provided in a building, the plurality of wireless APs wirelessly accessing a mobile terminal entering the building to receive a phone number from the mobile terminal;

a fire alarm receiving the phone number from the wireless APs to register the mobile terminal as a target terminal, transmitting positions of the wireless APs in the building and an electronic map of an inside of the building to the target terminal through the wireless APs, and when sensing a fire, transmitting a position of the fire and an alert message to the target terminal; and

the mobile terminal receiving and storing the positions of the wireless APs and the electronic map, and when receiving the alert message, outputting a map image and a voice message for guiding to an exit, wherein the mobile terminal includes;

an AP access module wirelessly accessing the wireless APs to transmit the phone number of the mobile terminal and to receive the positions of the wireless APs and the electronic map;

an electronic map storage memory storing the positions of the wireless APs and the electronic map received from the fire alarm;

a locator sensing the strength of radio signals received from at least three wireless APs to pinpoint the mobile terminal in the building; and

an evacuation guiding unit grasping an exit adjacent to the mobile terminal in the building on the electronic map to indicate a direction of evacuation when the alert message is received.

2. The fire alarm apparatus of claim 1, wherein the fire alarm includes:

a target terminal register receiving the phone number of the wireless APs and registering the mobile terminal as the target terminal;

a fire sensor sensing an occurrence of the fire, the position of the fire, and a direction in which smoke flows;

a message transmitter transmitting the alert message to the target terminal when the occurrence of the fire is sensed; and

an electronic map database (DB) storing the electronic map and the positions of the wireless APs.

3. The fire alarm apparatus of claim 2, wherein when a wireless link is disconnected for a predetermined time after the mobile terminal is registered as the target terminal, the target terminal is deleted from a target terminal registration.

4. The fire alarm apparatus of claim 2, wherein the fire alarm sends a request for capturing an image of a scene of the fire to a mobile terminal wirelessly linked to a wireless AP located adjacent to the fire, receives the captured image, and transmits the received captured image to a fire station.

5. The fire alarm apparatus of claim 1, wherein the fire alarm includes a target terminal distribution detector identifying the number of mobile terminals wirelessly linked to a wireless AP to grasp a positional distribution of the mobile terminal in the building.

6. The fire alarm apparatus of claim 2, wherein the message transmitter transmits a positional distribution of mobile terminals in the building and the alert message to the target terminal, wherein the evacuation guiding unit, at a highest priority, guides the target terminal to an exit where a positional distribution of the mobile terminals in the building is smallest among a plurality of exits in the building.

7. The fire alarm apparatus of claim 2, wherein the message transmitter transmits the position of the fire and the direction in which the smoke flows and the alert message to the target terminal in the building.

8. The fire alarm apparatus of claim 7, wherein the evacuation guiding unit guides the target terminal to an exit farthest from the position of the fire among exits to which the flow of smoke is directed.
