For convenience of description, a system and method for notifying a zone entry / departure service according to the present invention will be described with reference to FIGS. 1 and 2.

As shown in FIG. 1, the area entry / departure notification service system according to the present invention includes an area display signal generator 110, an area display signal receiver 120, a monitor terminal 130, and a location information transfer middleware 140 and 170. , Location information management server 150, area entry / exit information providing server 160, the monitor terminal 180 and the like.

In detail, the area display signal generator 110 generates a beacon signal including the location identification information. The location identification information is information for identifying the location of the area display signal generator, and may use a unique number of the area display signal generator or location information on which the area display generator is installed. In case of using the unique number of the area display signal generator (eg, the serial number of the device), the information on the location where the area display signal generator is installed in the location information management server 150 should be registered in advance. Even if location information is used, the location information management server 150 or the like should be able to interpret the contents.

The beacon signal transmitted from the area display signal generator 110 is a signal for guiding position measurement, and uses a short range wireless communication technology having a narrow range of beacon signal for accurate position measurement, and preferably Zigbee. Take advantage of wireless data network technology.

Zigbee is one of the IEEE 802.15.4 standards supporting near field communication. It performs near field communication within 10 to 20 meters in wireless networking in homes and offices, and it is different from other wireless communication technologies such as IEEE 802.1 or 802.15. Otherwise, this technology is suitable for the small size, low power, and low price market where simple functions are required. In addition, Zigbee can combine transceivers with sensors (motion, light, temperature, temperature, humidity, etc.) to form a large sensor network, using three frequency bands for transmission rates from 20 to 250 Kbps up to 100M. It supports up to 255 devices in one wireless network at 2.4GHz, and expands up to 65,000 nodes.

Meanwhile, an monitored person (eg, a child, a disabled person, an elderly person, etc.) having an area display signal receiver 120 refers to a communication area (that is, an area capable of receiving a beacon signal) of the area display signal transmitter. When entering the 'beacon signal reception area' for convenience, the area display signal receiver 120 receives the beacon signal and transmits the location identification information to the monitor terminal 130. In this case, the area display signal receiver 120 may be connected to the terminal to be monitored to a connection cable or may be provided inside the terminal to be monitored as a built-in type.

The monitored terminal 130 transmits the location identification information and its own terminal identification information (ie, the terminal identification information of the monitored terminal) to the location information management server 150. If the location information management server 150 is connected to the wired or wireless network, the monitored terminal 130 transmits the information to the location information delivery middleware 140 through the mobile communication network, and the location information delivery middleware 140. ) Transmits the received information to the location information management server 150 through a wired or wireless network.

Meanwhile, the area entry / exit information is generated based on the location identification information. When the monitored person is located outside the beacon signal receiving area, the location information management server 150 does not receive the location identification information. If the monitor enters the beacon signal receiving area, the location information management server 150 receives the location identification information of the corresponding area display signal generator. And, if the monitored person continues to be present in the beacon signal receiving area, the location information management server 150 will receive the same location identification information, and if the monitored person leaves the beacon signal receiving area, the location information management server 150 may not receive the location identification information or may receive different location identification information (this is the case when entering another beacon signal receiving area). Therefore, the location information management server 150 determines to enter the area corresponding to the location identification information when receiving the location identification information different from the previous, and generates location entry / departure information including these contents, If the same location identification information is not received, it is determined that the departure from the area corresponding to the location identification information and generates location entry / exit information including this content.

The location information management server 150 transmits the monitor terminal identification information and the area entry / departure information generated as described above to the area entry / departure information providing server 160. The area entry / exit information providing server 160 transmits the area entry / exit information to the monitor terminal 180 corresponding to the monitor terminal identification information.

In this case, similarly, if the area entry / exit information providing server 160 is connected to the wired / wireless network, the area entry / exit information providing server 160 moves to the location information transfer middleware 170 through the wired / wireless network. The supervisor terminal identification information and the area entry / departure information are transmitted, and the location information delivery middleware 170 receives the area entry / departure information through the mobile communication network.

The image information corresponding to the preset time (eg, 5 minutes before and after the reception time) may be extracted.

On the other hand, the location information management server 350 checks the area entry / exit service subscription information based on the monitor terminal identification information, and extracts the image output device identification information using this. In the area entry / exit service subscription information, contents of subscriber (monitor), monitor terminal identification number, monitor name, monitor terminal identification number, video output device identification number, etc. are registered in advance. If registered, the image output device 380 is located closest to the position of the monitor terminal after tracking the position of the monitor terminal using a known positioning technology (eg, a GPS method) based on the monitor terminal identification number. Extract identification information of.

The location information management server 350 transmits the image output device identification information and the image information generated as described above to the image information providing server, and the image information providing server 360 corresponds to the image output device identification information.
