Here, in the actual implementation of the location monitoring system according to an embodiment of the present invention, the location information providing server 120, location monitoring server 130, subscriber information database 132 and location display name database 134 are combined with each other May be implemented.

2 is a diagram briefly illustrating an internal configuration of a location monitoring server according to an exemplary embodiment of the present invention.

The location monitoring server 130 according to the embodiment of the present invention may include a program storage module 1310, a memory 1320, an input / output unit 1330, a network interface card (NIC) (hereinafter referred to as a 'NIC') ( 1340, subscriber information processing module 1350, location indication name checking module 1360, monitoring message generation module 1370, and database management module 1380.

The program storage module 1310 may include a location checking program for identifying a place where the subscriber is located from the place identification information, a location display name extraction program for extracting a preset location indication name corresponding to the extracted place identification information, and the subscriber. Various programs for operating the location monitoring server 130, such as a database management program for data input and output control of the information database 132 and the location display name database 134 is stored.

The memory 1320 is a part for temporarily storing data processed by the control module 1390. That is, the memory 1320 receives and temporarily stores the remote screen identification information checked by the subscriber information processing module 1350 based on the received terminal information, and displays the location display name checking module 1360 according to the received place identification information. Receive and save the location indication name checked in Temporarily. The provision of the temporarily stored remote screen identification information and the location display name to the monitoring message generating module 1370 serves to support the generation of the monitoring message.

The input / output unit 1330 is a part in which an input device such as a keyboard or a mouse that supports an administrator operating the location monitoring server 130 to input, modify, and delete subscriber information or location display name setting information for each subscriber is implemented. In addition, the input and output unit 1330 is implemented by a monitor for the administrator to check the operating state of the location monitoring server 130, and the like.

The NIC 1340 is a communication module that provides a communication interface for transmitting and receiving data between the location monitoring server 130 and the Internet network. That is, the NIC 1340 receives the terminal information and the place identification information from the Internet network, transmits the information to the control module 1390, and transmits the monitoring message received through the control module 1530 to the Internet network.

The subscriber information processing module 1350 checks the terminal information received from the Internet network, and then calls the subscriber information, remote screen identification information, and the like stored from the subscriber information database 132.

The location display name checking module 1360 may preset the place where the subscriber is located by using the location identification information received from the location information providing server 120 and the subscriber information confirmed through the subscriber information processing module 1350. It checks the location marker.

Here, in setting the location display name for a specific place, the subscriber may set not only a name indicating the place but also an image, a map screen, a special character, etc. indicating the specific place. Accordingly, the location display name checking module 1360 may serve to change the form suitable for the transmission format of the monitoring message after calling the location display name of various types preset by the subscriber.

The monitoring message generation module 1370 generates a monitoring message by using the remote screen identification information confirmed by the subscriber information processing module 1350 and the location indication name confirmed by the location indication name checking module 1360. To perform. In addition, the monitoring message generation module 1370 also generates a monitoring message and then requests to transmit the generated monitoring message to the location display area 140.

The database management module 1380 manages input / output of various pieces of information data stored in the subscriber information database 132 and the location indication name database 134. That is, when the database management module 1380 receives a request for inputting the information data through the control module 1390, the database management module 1380 checks whether the input requested information data is for input or change of subscriber information or for input or change of a location indication name.

3 is a flowchart illustrating a Wi-Fi radio map construction method and a Wi-Fi radio map confirmation method according to an embodiment of the present invention.

In performing a location monitoring service according to an embodiment of the present invention, a Wi-Fi radio map must be generated in advance and stored in a location information providing server. In the Wi-Fi radio map generation method as described above, a first method of constructing a Wi-Fi radio map by collectively collecting signal fingerprint information by a workplace, a school, a service provider, or the like, and a signal received by a plurality of subscriber stations The second method of constructing a Wi-Fi radio map by collecting fingerprint information, and a Wi-Fi radio map constructed by using signal information received from subscriber terminals after constructing a Wi-Fi radio map in a batch. A third method of adding or modifying the -Fi radio map may be used.

In the following description, the second method of generating a Wi-Fi radio map using signal fingerprint information obtained from a plurality of subscriber stations will be described.

For the location monitoring service according to the embodiment of the present invention, a place name for each place is previously assigned. Place name assignment for each place is preferably allotted by the company providing the location monitoring service.

In addition, for location monitoring services, place identification information for each place should be allocated. Here, a place name, a uniquely assigned ID, a phone number of the place, etc. may be used as the place identification information.

When the place name and place identification information for each place are allocated in this way, a mapping table between the place name and the place identification information allocated to the specific place is generated (S310).

Then, by using the aforementioned first to third methods, the signal fingerprint information measured at each place is collected, and then the collected signal fingerprint information is mapped to the place identification information at which the corresponding signal fingerprint information is measured. Build a radio map (S320).

In this case, the signal fingerprint information and the place identification information may be mapped one-to-one, and a plurality of signal fingerprint information may be mapped to one place identification information. Here, the mapping method between the signal fingerprint information and the place identification information will be described in detail with reference to FIG. 4.

In the location monitoring service system in which the Wi-Fi radio map is constructed as described above, the subscriber station 112 uses the information of one or more wired / wireless APs identified at the location where the Wi-Fi radio map is located and the signal fingerprint information by using the reception strength measured from the corresponding wired / wireless APs. Create Then, the generated signal fingerprint information is transmitted to the location information providing server 120.

When the signal fingerprint information is received from the subscriber station 112 (S330), the location information providing server 120 checks the request message transmitted with the signal fingerprint information, so that the received request message is a request for registration of the signal fingerprint information. Whether it is a message or a request message for confirming a place is determined (S340).

If it is confirmed that the received request message is a signal fingerprint information registration request message, and receives a place name from the subscriber station 112 (S350). At this time, the subscriber may be set to enter the place name directly, but the location information providing server 120 is to add the place list to the subscriber station 112 so that the place name is input in consideration of the characteristics of the database is built by a plurality of subscriber stations ), It is preferable to set the subscriber to select a place name located from the list of provided places.

When the place name is selected by the subscriber station 112, the place identification information previously assigned to the place name is brought (S352). At this time, when there is no place identification information allocated to the place name selected by the subscriber station 112, the location information providing server 120 generates new place identification information and maps it to the input place name.

After importing or generating place identification information from the pre-stored Wi-Fi radio map, the location information providing server 120 sets place identification information mapped to the signal fingerprint information received in step S330 (S354). In this case, a plurality of signal fingerprint information may be mapped to one place identification information, and unique place identification information may be mapped to each signal fingerprint information. Here, when unique place identification information is mapped to each signal fingerprint information, it is preferable to set so that a plurality of place identification information is mapped to one place name. In the following description, a plurality of signal fingerprint information is mapped to one place identification information, and one place identification information will be described based on mapping to one place name.

The mapping information between the signal fingerprint information, the place identification information, and the place name set as described above is registered in the Wi-Fi radio map (S356). Accordingly, when the place confirmation request is transmitted from the subscriber station later, the place name where the subscriber station is located can be detected from the received signal fingerprint information.

On the other hand, if it is confirmed in step S340 that the request message received with the signal fingerprint information is a place confirmation request message, the received signal fingerprint information and the signal fingerprint information of the Wi-Fi radio map previously registered in the location information providing server 120 Compare (S350).

The location information providing server 120 detects one or more signal fingerprint information most similar to the signal fingerprint information received from the subscriber station 112 among the plurality of signal fingerprint information previously registered in the Wi-Fi radio map (S362).

To this end, the location information providing server 120 compares the signal fingerprint information received from the subscriber terminal 112 with all signal fingerprints registered in advance.

At this time, the comparison between the signal fingerprints may be used to compare similar information of the signal fingerprint generated by the radio signal received from each wired or wireless AP (120). That is, the signal fingerprint is viewed as a vector having the received strength from each wired / wireless AP 120 as a factor, and the Euclidean distance between the received signal fingerprint and each signal fingerprint included in the signal fingerprint set ( Ecuclidean distance) is calculated and the signal with the smallest difference is detected by the most similar signal fingerprint.

As described above, Wi-Fi can be detected using various methods such as not only detecting similar signal fingerprints by calculating the Euclidean distance but also detecting similar signal fingerprints using variance and standard deviation of the received signal strength. Signal fingerprint information most similar to the signal fingerprint information received from the subscriber station 112 may be detected from the plurality of signal fingerprint information previously registered in the radio map. Since such content is well known among those skilled in the art, a detailed description thereof will be omitted.

In operation S364, location identification information on which the detected signal fingerprint information is mapped is identified as the signal fingerprint information most similar to the received signal fingerprint information.

By the above method, if the place identification information corresponding to the signal fingerprint information received from the subscriber terminal 112 is determined, the place identification information is transmitted to the location monitoring server 130, whereby the subscriber at the location monitoring server 130 It is possible to check the location of the location (S366).

4 is an exemplary diagram briefly illustrating a mapping table configuration of a Wi-Fi radio map stored in a location information providing server according to an exemplary embodiment of the present invention.

The Wi-Fi radio map according to the embodiment of the present invention includes an AP table 410, a signal fingerprint table 420, a place table 430, and a registration place table 440.

The AP table 410 is a table for storing wired and wireless AP information for transmitting a radio signal to the subscriber station 112. The AP table 410 is an AP identifier assigned to each wired / wireless AP, a manufacturer of the wired / wireless AP, and a unique value assigned to each wired / wireless AP. It includes the MAC address and location information where the wired / wireless AP is installed. Here, the AP identifier should be used so as not to overlap with other wired / wireless APs. Accordingly, a MAC address uniquely assigned to each wired / wireless AP may be used as it is.

Here, the AP table 410 according to an embodiment of the present invention includes the location information on which the wired / wireless AP is installed, and when the location of the wired / wireless AP installed is changed, the location of the wired / wireless AP is transmitted to the location information providing server 120. It should be set up to be notified of the change. The location information providing server 120 notified of the location change of the wired / wireless AP removes all signal fingerprint tables related to the wired / wireless AP notified of the location change from the Wi-Fi radio map, and thereafter, signal fingerprint information related to the wired / wireless AP. When is newly received, by newly generating and storing a signal fingerprint table related to the wired / wireless AP, the newly stored signal fingerprint table can be used in determining a location where the subscriber station 112 is located later.

The signal fingerprint table 420 is tabled by linking the reception strength of the wireless signal measured by the subscriber station 112 at an arbitrary position with the information of the wired / wireless AP that transmitted the wireless signal. The signal fingerprint table 420 is included. In addition, an identifier for identifying each signal fingerprint table 420 is used as data of a signal fingerprint identifier field of a registration place table to be described later. Here, the signal fingerprint table 420 includes a reception strength, an AP identifier, and a creation date field.

The place table 430 is an area in which place information received from an operator or subscriber of a location monitoring system is stored, and is a table in which place names and unique place IDs assigned to respective places are mapped. That is, the place table 430 includes place information including place name and address inputted by the operator or subscriber of the location monitoring system using the subscriber terminal 112 or the computer, and the like, and is uniquely assigned to the place. Is set.

The registration place table 440 is a table in which signal fingerprint information received from the subscriber station 112 and location identification information are mapped. Although FIG. 4 illustrates a table in which signal fingerprint information and a place ID are mapped, when a unique place name is assigned to each place, a place name may be used instead of a place ID. In this case, the place table 430 may be omitted. It may be. In the following description, the place ID is mapped to the registration place table 440.

In generating the Wi-Fi radio map, the location information providing server 120 checks the place ID corresponding to the received place name when the place name is received from the subscriber station 112 together with the signal fingerprint information. Then, a signal fingerprint table 420 including the signal fingerprint information received from the subscriber terminal 112 is generated, and stored in the registration place table 440 in association with the identifier and the place ID of the generated signal fingerprint table 420. Let's do it. Accordingly, the registration place table 440 includes a signal fingerprint table identifier, a registration date and time, a registrant, and a place ID field.

Here, in the actual implementation of the present invention, the AP table 410, the signal fingerprint table 420, the place table 430 and the registration place table 440 shown in FIG. 4 may be implemented in various forms. .

5 is a flowchart illustrating a location monitoring method according to an embodiment of the present invention.

Before executing the location monitoring service according to an embodiment of the present invention, a Wi-Fi radio map should be constructed (S510). As mentioned above, the Wi-Fi radio map is a first method for constructing a Wi-Fi radio map in a batch by a workplace, a school, or a service provider. The Wi-Fi radio map uses signal fingerprint information collected from a plurality of subscriber terminals. The second method, the first method, and the second method of constructing the radio map may be constructed through a mixed third method.

In addition, the location monitoring system should establish a subscriber information database 132 in which the information of the location monitoring service subscriber is stored (S520). In this case, the subscriber information database 132 stores information related to the subscriber station 112 and information of the remote screen 146 selected as an object for displaying the location of the subscriber.

Then, the location monitoring system establishes the location display name database 134 by setting the display method on the remote screen 146 for the location of the subscriber (S530). To this end, the location monitoring server 130 is selected or directly input the place to set the location display name from the subscriber.

When a place for setting the location display name is selected by the subscriber, the subscriber station 112 or the computer is provided with a location display name input window. The subscriber may set the location display name of the room, lecture, meeting, going out, vacation, etc. via the provided location display name input window.

After the Wi-Fi radio map, the subscriber information database 132, and the location indication name database 134 are constructed as described above, when the subscriber enters a specific area, that is, the subscriber location area 110, the subscriber station 112 receives the subscriber. The wireless signal is received from at least one first wired or wireless AP 114 installed in the location area 110 (S540). The subscriber station 112 generates the signal fingerprint information using the strength of the received wireless signal and the information of the first wired / wireless AP 112 which has transmitted the wireless signal.

The subscriber station 112 generates a location monitoring request message including the generated signaling fingerprint information for the request for providing the location monitoring service, and transmits the location monitoring information to the location information providing server 120 and the location monitoring server 130. At this time, the location monitoring request message includes terminal information (telephone number, terminal unique number, etc.) together with signal fingerprint information.

Alternatively, the location monitoring request message may be transmitted to the location monitoring server 130 only when the subscriber directly requests the subscriber station 112 to provide the location monitoring service.

In addition, when one or more first wired / wireless APs 114 installed in the subscriber location area 110 recognize that the subscriber station 112 has entered the jurisdiction, it transmits a location monitoring request message to the corresponding subscriber station 112. In response to receiving the location monitoring request message transmission request, the subscriber station 112 may generate a location monitoring request message including the signal fingerprint information and the terminal information and transmit the location monitoring request message to the location monitoring server 130. .

When the location monitoring request message of the subscriber station 112 is received through the Internet network, the location information providing server 120 responds to the signal fingerprint information included in the location monitoring request message by using a Wi-Fi radio map stored in advance. The location identification information is checked (S550). Then, the confirmed location identification information is transmitted to the location monitoring server 130. At this time, the location information providing server 120 may utilize a place name as place identification information, or may use a place ID.

The location monitoring server 130 receiving the terminal information through the location monitoring request message extracts the subscriber information and the remote screen identification information corresponding to the terminal information received from the subscriber information database 132 (S560).

The location monitoring server 130 confirms the location identification information set in the subscriber location area 110 from the location information providing server 120 and checks the subscriber information through the subscriber information database 132. The searcher checks the location indication name set by the subscriber for the corresponding place identification information in advance (S570).

The location monitoring server 130 generates a monitoring message including the remote screen identification information extracted in step S560 and the location indication name identified in step S570. In operation S580, the generated monitoring message is transmitted to the location display area 140 where the remote screen 146, which is identified through the remote screen identification information, is located.

The monitoring message transmitted to the location display area 140 is transmitted to the remote screen 146 through the personal server 144 or the second wired / wireless AP 142, and the remote screen 146 extracts the location indication name from the monitoring message. Display on the screen (S590).

Here, in the actual implementation of the present invention, the Wi-Fi radio map may be stored in the subscriber terminal 112, whereby the location information providing server 120 may be omitted. In this case, the location monitoring server 130 should receive the place identification information directly from the subscriber terminal 112.

Alternatively, the Wi-Fi radio map may be registered on the personal server 144. At this time, the location information providing server 120 transmits the signal fingerprint information received from the subscriber terminal 112 to the personal server 144, and then monitors the monitoring message using the location identification information received from the personal server 144.
