Fig. 1 is a block diagram showing an example of a child-proof prevention system.

Referring to FIG. 1, the child preventive system 10 may include the child preventive device 100, the user terminal 200, and the search terminal 300.

The child preventive device 100 can communicate with the user terminal 200.

The user terminal 200 may be a personal computer (PC), a data server, or a portable device.

Portable devices include laptop computers, mobile phones, smart phones, tablet PCs, mobile internet devices (MIDs), personal digital assistants (PDAs), enterprise digital assistants (EDAs) A digital still camera, a digital video camera, a portable multimedia player (PMP), a personal navigation device or a portable navigation device (PND), a handheld game console, an e-book e-book, or a smart device.

Smart devices can be implemented as smart watch watches or smart bands. That is, the user terminal 200 may be a user wearable or wearable wearable device.

The child preventive device 100 can read the user terminal 200 using a tag reader and receive the terminal information. The terminal information may include at least one of a terminal ID and a terminal alias. The terminal ID includes the group alias of the group to which it belongs, and may further include a number to distinguish each user.

The child preventive device 100 can communicate with the user terminal 200 through the search terminal 300. That is, the search terminal 300 can support the anti-malware prevention device 100 to communicate with the user terminal 200. For example, it is very inefficient if the user must travel a great distance in order to communicate with the preventive device 100 in a wide area such as an amusement park or an amusement park. Therefore, the user can use the search terminal 300, Preventive device 100 according to an embodiment of the present invention.

The user terminal 200 can communicate with the prevention device 100 via the communication network. For example, the communication network may be an Internet communication network, an intranet, a local area network (LAN), a wireless LAN, or an IEEE 802.11 based Wi-Fi.

Hereinafter, the operation of the child-proof prevention apparatus 100 will be described in detail.

Fig. 2 is a schematic block diagram of the child-proofing apparatus shown in Fig. 1, and Fig. 3 is a flowchart showing an example of an operation of the controller shown in Fig. 2 to register a user in a group.

2 to 3, the prevention device 100 may include a memory 110, a controller 130, a transceiver 150, and a pager 170.

The controller 130 can confirm whether a group exists in the memory 110 in response to the terminal information (S410).

If there is no group in the memory 110, the controller 130 may generate the group using the terminal information (S413). At this time, the controller 130 may assign at least one of the group ID and the group alias to the generated group. The group ID can contain one letter of the alphabet and four digits, and the group alias can contain all the characters that can be entered. For example, the controller 130 may assign the group ID to the first group A0001, the group alias to the tiger, the group ID to the second group A0010, and the group alias to the rabbit. Although only the second group is described as an example, the present invention is not limited to this, and at least one of the group ID and the group alias may be assigned differently so that a large number of groups that can be distinguished from each other can be created. The controller 130 may store the generated plurality of groups in the memory 110. [

The prevention device 100 includes a display, and the controller 130 can display on the display whether or not the generated groups are being used. An example of a state in which the controller 130 generates a plurality of groups 111-1 to 111-n and stores them in the memory 110 is shown in FIG. At this time, some of the plurality of groups 111-1 to 111-n may form a first relationship. The first relationship may be a friendship relationship between at least two groups.

If the group exists in the prevention device 100, or if the controller 130 has created the group, the controller 130 can select at least one of the generated groups (S415). For example, the controller 130 may select at least one group from among the generated groups to register the user.

The transceiver 150 may include a communication module and may receive terminal information from the user terminal 200. The transceiver 150 can receive terminal information by recognizing a tag of the user terminal 200 using a tag reader. The controller 130 may process the terminal information (S417). For example, the controller 130 may receive and process terminal information corresponding to each of a plurality of users to register in order to register a user in a group. The controller 130 processes the terminal information in the form of a friend relationship (a first relationship, a second relationship), a friend relationship (first relationship, a second relationship) Connection, location lookup, and call signaling.

The controller 130 may store the terminal information in the memory 110.

The terminal information may include at least one of a terminal ID and a terminal alias. The terminal ID includes the group alias of the group to which it belongs, and may further include a number to distinguish each user. For example, the first user and the second user belonging to the tiger group may have the terminal IDs of tiger (1) and tiger (2), respectively. If there is no group to which the user belongs, the terminal ID may display a randomly listed character or display a message indicating that it is not registered. A terminal alias may include a name, alias, etc. to identify an individual user. For example, the alias of the first user may be Hong Gil Dong, and the alias of the second user may be Hongsun. In this case, the controller 130 can display the first user as a tiger (1) -Holyildong and the second user as a tiger (2) -Hohsun Lee on the display.

The controller 130 can select a user based on the terminal information (S419). The controller 130 selects a user who wants to form a friend relationship (a first relationship, a second relationship) among a plurality of users corresponding to the received terminal information to form a friend relationship (first relationship, second relationship) can do. The controller 130 can select the user only when the terminal information does not include an error.

The controller 130 may register the selected users in the selected group (S421). For example, the controller 130 may register the first user and the second user in the first group, and register the third user, the fourth user, and the fifth user in the second group. More specifically, the controller 130 can register the users included in the family of Hong Kil-Dong in the elephant group, and can efficiently manage the groups by registering the users included in the family of Ko Kil-Dong in the rabbit group .

The controller 130 may determine whether it is necessary to additionally register the user to the group (S423).

If it is necessary to additionally register the user, the controller 130 may further process the terminal information (S417). At this time, the controller 130 may repeat the steps necessary to register the user in the group.

If there is no need to additionally register the user, the controller 130 can terminate the operation.

The controller 130 may also form a first relationship between the groups. For example, the controller 130 may select the group 111-2 and the group 111-3 to form the first relationship. The first relationship may be a friend relationship between at least two selected groups.

The operation of the pager 170 will be described later with reference to Figs. 12 to 14. Fig.

Hereinafter, the operation in which the controller 130 forms the first relationship between the groups and the operation of forming the second relationship between the users will be described in detail. The second relationship may be a friend relationship between at least two users selected.

FIG. 5 is a flowchart showing an example of an operation in which a controller forms a first relationship or a second relationship, FIG. 6 shows an example in which a plurality of users form a second relationship, and FIG. Respectively, form a second relationship.

5 to 7, the controller 130 may process the terminal information received from the user terminal 200 by the transceiver 150 (S610). The transceiver 150 can receive the terminal information by recognizing the tag of the user terminal 200 using the tag reader of the prevention device 100. [ For example, the controller 130 may process terminal information corresponding to each of a plurality of users to register in order to register a user in a group.

The controller 130 may process the terminal information corresponding to each of the plurality of users to form a first group-to-group relationship or to form a second relationship between the users. The terminal information may include at least one of a terminal ID and a terminal alias. The terminal ID includes the group alias of the group to which it belongs, and may further include a number to distinguish each user. A terminal alias may include a name, alias, etc. to identify an individual user.

The controller 130 can select a user based on the terminal information (S613). For example, the controller 130 may select a plurality of users who wish to form a friend relationship (a first relationship or a second relationship). In addition, the controller 130 can select the user only when the terminal information does not include an error.

The controller 130 may determine whether the selected user forms a first relationship between different groups included (S615). For example, when the controller 130 selects the first user and the second user, the controller 130 determines the first relationship between the first group including the first user and the second group including the second user, Can be formed.

If it is desired to form a first relationship between different groups, the controller 130 may form a first relationship between the different groups (S619). Fig. 4 shows a state in which the different groups 111-2 and 111-3 form the first relationship.

The controller 130 may use a tag reader to search for a group to which the user belongs or to form a first relationship between the groups based on at least one of the group ID and the group alias. For example, the controller 130 may search for a group using a tag reader or search at least one of a group ID and a group alias to select a plurality of groups, and form a first relationship between the selected plurality of groups .

For example, the controller 130 may form a first relationship between the group 710 and the group 730 and a first relationship between the group 730 and the group 750. For example, At this time, although the group 710 and the group 750 do not form the first relationship, since the group 710 and the group 750 form the first relationship with the group 730, A first group may be formed between the first group 710 and the group 750. [ Based on the input of the user, the controller 130 may optionally not form the first group between the group 710 and the group 750. [

The controller 130 may form a second relationship between users included in different groups forming the first relationship. For example, the controller 130 forms a second relationship between each user included in the group 111-2 forming the first relationship and each user included in the group 111-3. can do.

In response to a request from users included in different groups, the controller 130 may independently terminate the second relationship between users, even though they have established a first relationship between the different groups. At this time, the users whose second relationship has not been canceled can continue to maintain the friend relationship (the first relationship, the second relationship).

If it is not desired to form a first relationship between different groups, the controller 130 may determine whether to form a second relationship between the selected users (S617).

If it is desired to establish a second relationship between the users, the controller 130 may form a second relationship between the users (S621). The controller 130 may use a tag reader or form a second relationship between users based on at least one of a terminal ID and a terminal alias. For example, the first group 810 may include a user 811 and a user 813 and the second group 830 may include a user 831, a user 833, and a user 835 have. The controller 130 can search for a plurality of users by using the tag reader of the prevention device 100 or by searching at least one of the terminal ID and the terminal alias in the display of the prevention device 100. [ In addition, the controller 130 may form a second relationship between a user 811 and a user 831 belonging to different groups among a plurality of users searched. The operation of forming the second relationship between the users belonging to different groups (tiger (1), duck (1)) may be as shown in Fig.

A second relationship can be automatically formed between all users belonging to the same group. For example, user 811 and user 813 may form a second relationship with each other, and user 831, user 833, and user 835 may form a second relationship with each other, The user 851 and the user 853 may also form a second relationship with each other.

The controller 130 may form a first relationship between the different groups if the users forming the second relationship in response to the user's input belong to different groups. For example, when the user 811 and the user 831 form a second relationship, the controller 130 forms a first relationship between the different first group 810 and the second group 830 can do.

If a user in a group is forming a second relationship with a user in another group, the controller 130 may form a second relationship between all users in the group and the user in the other group. For example, if the user 833 of the second group 830 and the user 851 of the third group 850 form a second relationship, then all the users 831, 833 in the second group 830 , 835 and the user 851 of the third group 850 can be formed.

The user 831 included in the second group 830 also forms a second relationship with the user 811 included in the first group 810 and the user 851 included in the third group 850 The controller 130 may form a second relationship between the user 811 and the user 851. In this case,

If the second group 830 forms a first relationship with the first group 810 and the third group 850, respectively, then the controller 130 can be applied to the first group 810 and the third group 850, A first relationship may be formed between the first group 810 and the third group 850.

When forming the first relationship between the plurality of groups, the controller 130 can search the plurality of groups by searching at least one of the group ID and the group alias of the prevention device 100. [ The controller 130 may form a first relationship between the plurality of groups searched.

In the case where the first relationship between the groups is formed (S619), the second relationship is formed between the users (S621), or when it is not necessary to form the second relationship between the users, It is possible to judge whether or not there is a need to form a relationship (S623).

If it is necessary to additionally establish a relationship between the user or the group, the controller 130 may further process the terminal information to be registered (S610). At this time, the controller 130 may repeat the steps necessary for forming the friendship relationship (the first relationship, the second relationship).

In addition, the controller 130 may terminate the first relationship between the groups, or the second relationship between the users. When terminating the second relationship between the users, the controller 130 may choose to either cancel the second relationship between the selected users, or to cancel the second relationship with all users of the group in which the selected user is included. For example, when canceling the second relationship between the user 833 and the user 851, the controller 130 terminates only the second relationship between the user 833 and the user 851, The second relationship of the user 851 and the second relationship of the user 833 and the user 851 and the second relationship of the user 835 and the user 851. [ An example of the operation in which the controller 130 releases the second relationship between two users (tiger 1, duck 1) is shown in Fig. An example of the operation in which the controller 130 releases the first relationship between two groups (tiger, duck) is shown in Fig.

When terminating the first relationship between the groups, the controller 130 may abort the second relationship between the users included in the revoked group. For example, when canceling the first relationship of the first group 810 and the second group 830, the controller 130 may cancel the second relationship between the user 811 and the user 831 . That is, the controller 130 may terminate all the second relationships connecting the first group 810 and the second group 830.

11 shows an example of an operation of receiving terminal information of a user terminal using a tag reader.

11, when the child-proof prevention apparatus 100 selects an arbitrary user terminal 200 using a tag reader, the controller 130 determines whether any user belongs to the display of the child prevention apparatus 100 All the users of the group in which the group is formed, all users in the other group in which the group is forming the first relationship, and all users in which the arbitrary user is forming the second relationship. In addition, the controller 130 may display the group or user who has been revoked by any user on the display of the prevention device 100. [ In addition, the controller 130 can display the status information of the users who form the friendship relationship (first relationship, second relationship) on the display of the prevention device 100. [ The status information may be information on the status of the user such as whether the terminal is returned or not.

12 shows a data flow of the lost child prevention system shown in Fig.

Referring to FIG. 12, the prevention device 100 may receive a location request from the first user (S1410). For example, the prevention device 100 may receive a location request from the first user via the display.

The child preventive device 100 responds to a position request of the first user by a user who forms a friend relationship (first relationship, second relationship) with the first user on the map stored in the child preventative device 100, (S1430), and transmits the location information of the users to the first user (S1450). An example of displaying the location of the other users on the map of the display in response to the location request of the first user and transmitting the location information of the other users to the first user is shown in FIG. 13, the first user may be the tiger 1 and the other users may be the tiger 2, the duck 1, and the duck 2.

(At least one of the group ID and the group alias), the terminal information (at least one of the terminal ID and the terminal alias), the location information (at least one of the coordinates and the location), and the user status For example, status information such as whether to return or not, and whether or not to leave).

The child preventive apparatus 100 can store a map in the memory 110 and can efficiently search a plurality of users by enlarging and reducing the map. The prevention device 100 includes a GPS module and can periodically receive position information from the user terminal 200. [ The user terminal 200 may transmit the location to the prevention device 100 using a beacon signal.

The location information may include at least one of coordinates on the map of the user, and information on the location according to the coordinates. For example, assume that a first user and a second user form a second relationship, a first user is near the carousel, and a second user is near the castle of magic. In the case where the first user transmits a position request of the second user to the childbearing prevention apparatus 100, the childbearing prevention apparatus 100 responds to the request of the first user by, on the map stored in the childbearing prevention apparatus 100 The location of users forming a friendship relationship (first relationship, second relationship) with the first user can be displayed. The second user on the map will be displayed at the location of the magical castle. The child-proofing apparatus 100 can display the position of the user on the map in the form of a blinking icon. The child preventive apparatus 100 may transmit at least one of the coordinate (x1, y1) of the second user and the information of the magic property corresponding to the coordinate (x1, y1) to the first user.

The prevention device 100 may store the location information of a plurality of users in the memory 110. [

The first user can request the second child user's call to the child prevention apparatus 100 based on the received location information (S1470).

The prevention device 100 may send a call signal to the second user in response to the call request of the first user (S1490). At this time, the child preventive apparatus 100 can use the pager 170 to transmit a paging signal to all users belonging to the group including the second user, or only to the second user. The paging signal may be at least one of beep, vibration, lightning, and pop-up messages. 2, the pager 170 is shown inside the child-proofing apparatus 100, but the present invention is not limited thereto and may be implemented outside the child- An example of the operation of sending a call signal to another user (duck 1) in response to a call request of a user (tiger 1) is shown in Fig.

Although the malfunction prevention device 100 has been described above, the configuration of the search terminal 300 may be the same as the malfunction prevention device 100 shown in FIG.
