Abstract

Provided are a system and method for guiding a visitor using a sensor network. The system includes: an entry approval requesting unit for requesting an entry approval of the visitor to the visitee terminal according to destination information; a route setting unit for setting a route along which the visitor terminal is to move to the destination, based on the destination information of the visitor, according to an entry approval result of the visitee terminal; a location detecting unit for detecting a current location of the visitor terminal based on identification information of the visitor terminal and location information of the sensor node, the identification information and the location information being obtained through the sensor network on the route; and a location confirming unit for confirming if the detected current location of the visitor terminal is out of a preset area.

Claims

1. A system for guiding a visitor using a sensor network, wherein the system is connected to a visitee terminal and communicates with a visitor terminal through the sensor network, the sensor network including sensor nodes having information on in-building locations, a sink node, a gateway, and a middleware, the system comprising:

an entry approval requesting unit for requesting an entry approval of the visitor to the visitee terminal according to destination information provided by the visitor;

a route setting unit for setting a route along which the visitor terminal is to move to the destination, based on the destination information of the visitor, according to an entry approval result of the visitee terminal;

a location detecting unit for detecting a current location of the visitor terminal based on identification information of the visitor terminal and location information of the sensor node communicating with the visitor terminal, the identification information and the location information being obtained through the sensor network on the route set by the route setting unit; and

a location confirming unit for confirming if the detected current location of the visitor terminal is out of a preset area.

2. The system of claim 1, where the visitor terminal includes a door controlling unit for controlling a closing/opening of a door installed in the destination.

3. The system of claim 1, further comprising:

a short-message-service (SMS) message transmitting unit for transmitting an SMS message to a previously registered portable terminal of a visitee terminal when the entry approval requesting unit does not receive the entry approval within a predetermined time.

4. The system of claim 1, further comprising:

an application providing unit for providing an application to provide a route from the current location of the visitor terminal to the destination.

5. The system of claim 1, wherein when information on a changed location of the visitee is transmitted from the visitee terminal, the entry approval requesting unit provides the location on the changed location of the visitee as the destination information to the route setting unit.

6. A method for guiding a visitor using a sensor network, wherein the sensor network includes a visitor terminal and a visitee terminal, where an application for a visitor guidance and a location detection is installed, a sensor node having information on in-building locations, a sink node, a gateway, and a middleware, the method comprising:

requesting an entry approval of the visitor to the visitee terminal according to destination information provided by the visitor;

setting a route along which the visitor terminal is to move up to the destination, based on the destination information of the visitor, according to an entry approval result of the visitee terminal;

detecting a current location of the visitor terminal based on identification information of the visitor terminal and location information of the sensor node communicating with the visitor terminal on the set route;

confirming if the detected current location of the visitor terminal is out of a preset area on the set route;

performing a room entry procedure of the visitor terminal according to a type of a door when the movement of the visitor terminal is completed.

7. The method of claim 6, wherein the setting route along which the visitor terminal is to move up to the destination, based on the destination information of the visitor, according to an entry approval result of the visitee terminal, includes:

notifying the presence of the visitor to a previously registered portable terminal of the visitee when the visitee terminal does not give the entry approval within a predetermined time.

8. The method of claim 6, wherein the setting route along which the visitor terminal is to move up to the destination, based on the destination information of the visitor, according to an entry approval result of the visitee terminal, includes:

modifying the location information of the visitee, which is changed by the visitee terminal, into the destination information of the visitor.

9. The method of claim 6, wherein the performing room entry procedure of the visitor terminal according to a type of a door when the movement of the visitor terminal is completed, includes

closing/opening the door in response to a door control command of the visitor terminal.
