Description

Mia tracking system device and its method

The present invention relates to an apparatus for tracking a lost child, and more particularly, to a lost child tracking system device and a method for tracing a moving line according to the movement of the lost child in a certain area so as to quickly find the lost child. .

In an effort to prevent the loss of infants, the rate of occurrence of infants is rarely reduced. Mia occurs mainly due to outings and outings with parents, and then neglects their parents' protection. In particular, younger children who begin to walk tend to be engrossed in things that they are interested in or interested in, so they disappear from the parent's view at the moment when their parents are at a loss. Occurs by moving it.

The occurrence of such a lost child is recognized as a social and national problem beyond the psychological and economic pain of a family, and thus various institutional devices are provided to resolve the lost child problem. In other words, in order to prevent the occurrence of the lost child, such as wearing the anti-mia bracelets and necklaces to check the identity of the infant, to expand the installation of CCTV or to use the smart phone to check the location of the child is typical. .

However, even if you wear identification bracelets or necklaces, it is not easy for parents to find their children quickly unless they are actively interested in them. In addition, the efforts to prevent the occurrence of the lost child through CCTV is limited to the method of acquiring the post-mortem information after the occurrence of the lost child. In addition, recently, the method of finding a lost child using a smart phone could not confirm the immediate location by the location information protection law, and in a situation in which a specific application where the location information was disclosed was not executed, only the current location of the lost child could be found within a radius of a neighboring base station. . That is because the location confirmation through the smart phone, etc. are mostly made within the zone (zone) serviced by the base station serving as a relay between the smart phone and the server.

Mia is most often caused by a child looking for a parent or immersed in an object of interest, etc. However, the above-mentioned effort to prevent the loss of a child may be a follow-up after the occurrence of a child or cannot accurately find the child's current position. .

Therefore, if the child's movement path can be identified, the child's current position can be actively determined at the early stage of the loss. For example, an area or location where a child may be lost may be a specific area (range) such as an amusement park or a mart, and in such an amusement park / mart, the child may be found at an early stage if the child is able to check a moving line.

An object of the present invention is to solve the above problems, by using the information generated in the terminal passing through a specific location to easily check the moving line of the child to prevent the occurrence of the missing child as well as to quickly lose the missing child The present invention provides a device for tracking a lost child and a method thereof.

According to a feature of the present invention for achieving the above object, a first terminal device for transmitting a positioning message at a predetermined time period; A second terminal device periodically transmitting a location message repeatedly when the location confirmation message is not received while communicating with the first terminal device; At least two location recognition devices for receiving location messages from the second terminal device; And a server receiving a location message from the location recognition device and transmitting the movement path information of the second terminal device to the first terminal device.

Here, the first terminal device and the second terminal device is characterized by using the same security code by performing a synchronization process.

The first terminal device displays a movement path alert of the second terminal device transmitted from the server only when a response message is not received from the second terminal device after the location confirmation message is transmitted.

The second terminal device is fixed to a child's bag or clothes by a fixing device, and when the second terminal device fixed by the fixing device is separated from the fixing device, the first terminal device, the location recognition device and the server. Send a warning message to

The location recognition device installed on the entrance side configured for entry and exit of a predetermined area among the location recognition devices includes a message for notifying a proximity state when the second terminal device approaches the communication range, and the first terminal device and the location recognition device. And to the server.

According to another feature of the invention, the second terminal device for communicating with the first terminal device determines whether to receive the location confirmation message from the first terminal device; A location message transmission step of periodically and repeatedly transmitting a location message indicating the location of the second terminal device when the location confirmation message has not been received in the determination step; A location message retransmission step of receiving at least two location recognition devices installed at a specific place and transmitting the location message according to the movement of the second terminal device to a server; And a movement path information transmitting step of transmitting, by the server, the movement path information of the second terminal device to be displayed on the first terminal device based on the location messages received from the location recognition devices. Is provided.

The first terminal device may display the movement route information by mapping the map information to map information corresponding to the current location.

According to the present invention having such a configuration, a location message that is repeatedly transmitted from a terminal device carried by a child when the child is separated from a certain distance by a parent while the parent and child carry a synchronized terminal device within a specific region. When the location recognition device installed in any place in the area receives and transmits it to the server, the server can easily identify the moving line the child is moving based on the location message received by the location recognition device.

Therefore, even if a child is lost because she moves to find a parent or curiosity about a particular object, the movement line of the child can be grasped immediately and closely.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, an apparatus for tracking a lost child according to the present invention and an embodiment thereof will be described in detail with reference to the accompanying drawings.

The present embodiment provides a technical feature for quickly finding a lost child by checking the moving path of the lost child when a lost child occurs in a certain area such as an amusement park or a mart. However, it is obvious that the present invention can be applied to perform a tracking function by expanding to a wider area other than a specific area such as an amusement park / mart mentioned in the following embodiments.

First, the overall system configuration of the apparatus for tracking a lost child of the present invention will be described with reference to FIG. 1, and a functional configuration for each configuration will be described with reference to FIG. 2. FIG. 1 is a block diagram of an apparatus for tracking a lost child according to a preferred embodiment of the present invention, and FIGS. 2A and 2B are block diagrams for some components disclosed in FIG. 1.

As shown in FIG. 1, the apparatus for tracking a lost child 100 is provided with a terminal 110 (hereinafter referred to as a first terminal device) possessed by a parent (guardian). The first terminal device 110 may be a smart phone or a specific terminal proposed for tracking lost children. And in the case of a smartphone, the application for tracking the missing child is installed and should be registered in the server to be described later, in the case of the terminal is usually distributed to the parents in the management center, such as an amusement park or mart, the server of the management center at the time of distribution ( 140). At the time of registration, the unique numbers of the smart phone and the terminal are registered, and synchronization with the second terminal device 120 to be described later is performed. In addition, the synchronization must be such that the first terminal device 110 and the second terminal device 120 use the same type of security code to exclude interference from other terminal devices. The first terminal device 110 transmits a location message to the second terminal device 120 and receives a response message from the second terminal device 120 so that the second terminal device 120 provides its own service. Determine if it is within range.

The second terminal device 120 is a terminal device possessed by a child, and provides a function of providing a location message to the following location recognition device 130 to selectively notify its location through communication with the first terminal device 110. Perform. Here, the location message is repeatedly transmitted only when the second terminal device 120 is out of the service range of the first terminal device 110. As described above, the second terminal device 120 uses the same security code through synchronization with the first terminal device 110.

The second terminal device 120 preferably has a structure that cannot be easily separated from the child's body due to the characteristics possessed by the child. In other words, young children often lose their own terminals easily, in which case it is difficult to find children. As an example of this, the second terminal device 120 is provided in a structure that is fixed by a hook device having a hook shape to a bag or clothes carried by a child.

On the other hand, the ring device is a general structure and a detailed description thereof will be omitted in this embodiment. However, when the fixing device of the second terminal device 120 is forcibly removed after the fixing, the second terminal device 120 is the first terminal device 110 or the position recognition device 130 to 130n described below and the server ( 140) to send a warning message. In the embodiment, the forced removal operation includes a case in which the ring device is separated by a method such as destruction or damage after the second terminal device 120 is synchronized with the first terminal device 110 without being separated in a normal manner. do. In addition, the second terminal device 120 has a configuration that transmits the warning message even when the power off (off). As such, by transmitting a warning message when the second terminal device 120 is lost, forcibly removed, or powered off, even if a situation in which the child is lost, the child may be quickly identified to find the child.

Position recognition device (130 ~ 130n) is installed in a specific area, such as an amusement park or mart, such as doors or intersections. The location recognition devices 130 to 130n may be installed according to the geographical conditions or characteristics of the area / range in which the location recognition devices 130 to 130n are installed, and the intervals of the installation may be adaptively determined according to the ability to transmit and receive messages. Is installed. The location recognition devices 130 to 130n serve to receive a location message selectively transmitted from the second terminal device 120.

Particularly, the location recognition device installed at the entrance and exit side of the location recognition device 130 to 130n, in addition to receiving the location message from the second terminal device 120, the second terminal device 120 is the location recognition device. When entering the communication range of the first terminal 110 and the server 140 performs a function for transmitting a message for notifying it. This is to notify the first terminal device 110 and the server 140 when the lost child enters the lost terminal when the lost child enters, thereby preventing the lost child from getting out of the doorway.

Acquire and manage information of the second terminal device 110 and the location recognition devices 130 to 130n, and when the location message is received from the location recognition devices 130 to 130n, the second terminal device to the first terminal device 110. The server 140 for transmitting the movement route information for confirming the movement of the movement line 120 is configured. In this case, the movement route information output from the first terminal device 110 may be displayed together with the information of the location recognition devices 130 to 130n, and furthermore, by a user interface (UI) mapped and displayed on the map information of the corresponding area. It would be more desirable to be displayed.

On the other hand, the server 140 also performs a function of monitoring the state of the plurality of location recognition devices 130 ~ 130n installed in a certain area. That is, the server transmits a request message to the location recognition devices 130 to 130n in a cyclic / random manner and receives the response message (ack) according to the request message (request). 130n) is determined to operate normally. On the other hand, the position recognition device (130 ~ 130n) does not transmit a response message (ack) is determined to be an error so that a quick check is made.

The apparatus for tracking a lost child system 100 according to the present embodiment further includes a signage 150 that displays information about the occurrence of missing information from the server 140. Mia occurrence notification information displayed includes text, video, video information. The signage 150 also performs a function of displaying the current location of the lost child when necessary. In other words, Mia displays the location of the terminal device. The signage 150 is installed in a place that many people can see in a specific area or a place where a high occurrence of mia is occurring.

Next, the configuration of the above-described second terminal device and the position recognition device will be described with reference to FIG. 2.

First, since most smartphones are applied to the first terminal device 110 owned by a parent, detailed description thereof will be omitted. In other words, the smart phone can be installed without various limitations, and therefore, it is necessary to install an application made for tracking the lost child proposed by the present embodiment. Of course, the smartphone will have to be registered on the relevant server or management system. On the other hand, when the first terminal device 110 is a general terminal, a wireless communication device for communication with the second terminal device 120 and the server 140 may be configured. In addition, a function of outputting the position and the moving copper wire of the second terminal device 120 or the like on a text or graphic screen should also be provided. In addition, when the deviation from the predetermined distance from the second terminal device 120 should also be provided with a function for notifying the alarm so that the parent can recognize. As such, when the first terminal device 110 of the general terminal type is distributed to the parent in the management center, the first terminal device 110 is synchronized with the second terminal device 120 with reference to the unique number.

The configuration of the second terminal device 120 is disclosed in FIG. 2A. The second terminal device 120 includes a wireless transmission / reception unit 122 that supports a short range wireless communication method with the first terminal device 110 and a wireless communication method with a location recognition device. Examples of the wireless transceiver 122 include a GPS receiver for communicating with a GPS, a ZigBee and Wi-Fi (WiFi) transmission method, and a mobile communication method such as 3G / 4G. In addition, the second terminal device 120 determines whether a location message is received from the first terminal device 110 according to a control operation of the controller (that is, referred to as a second terminal device controller) 124. If the acknowledgment message is not received within a predetermined time, a function of checking the time to repeatedly transmit the location message in a predetermined time unit is also included. The timer 126 is used for time checking. And the charging unit 128 for charging the rechargeable battery 127 to supply power should also be configured. Of course, in addition to the rechargeable battery 127, a general battery may be used as a power source.

The configuration of the position recognition devices 130 to 130n will be described with reference to FIG. 2B. As shown in FIG. 2B, various wireless communication methods are supported for communication with the second terminal device 120 and the server 140. To this end, a ZigBee and a Wi-Fi (WiFi) transmission method, a local area network such as Ethernet (Ethernet), a wireless transmission and reception unit 132 supporting a mobile communication method such as 3G / 4G is configured. In addition, since the position recognition devices 130 to 130n are fixedly installed by a bracket or the like indoors or outdoors within a specific region, the position recognition devices 130 to 130n receive power from a power supply unit 134 using a general power source or a solar cell (solar heat). In addition, the position recognition devices 130 to 130n include a control unit (that is, referred to as a “location recognition device control unit” 134) for controlling communication with the second terminal device 120 and the server 140.

Next, a method of preventing the occurrence of the missing child by using the apparatus for tracking the lost child having the above-described configuration and detecting the lost child by tracing the moving lines of the lost child even when the lost child will be described.

First, when a parent visits a specific area such as an amusement park or a large mart, the parent registers the first terminal device 110, which is his smart phone, to the server 140 (s100). The registration needs to be executed only once, and when the user visits the corresponding area again after registration, the first terminal device 110 automatically activates a function for tracking the lost child. If the parent does not have the first terminal device 110, the parent visits the management center or the like as needed to receive the terminal device. At this time, the terminal device is already registered in the server 140 of the management center.

As such, when the registration of the first terminal device 110 carried by the parent is completed, the first terminal device 110 is synchronized with the second terminal device 120 carried by the child (S102). As an example of synchronization, for example, when the first terminal device 100 is registered in the server 140, the second terminal device 120 is automatically searched for missing children, and synchronization with the found second terminal device 120 is performed. Is executed. When the synchronization is completed, the same type of security code is assigned to prevent interference with other terminal devices. In this case, when there are two or more second terminal devices 120, one first terminal device 110 may be synchronized with a plurality of second terminal devices 120 to 120n, respectively. As a result of the synchronization, the first terminal device 110 and the plurality of second terminal devices 120 to 120n are each synchronized with a security code independently assigned. That is, the first terminal device 110 is in a state capable of communicating with at least one second terminal device 120-120n.

When the synchronization is achieved, the lost child tracking system through the first terminal device 110 is executed. That is, the parent and the child start to move in a specific area such as an amusement park or a large mart with the first terminal device 110 and the second terminal device 120 respectively.

The first terminal device 110 transmits a positioning message for confirming whether the second terminal device 120 carried by the child exists within a predetermined communication range in a periodic manner or a random manner (S104). In the embodiment, the location message is transmitted at a fixed time interval (ex: 1 minute). When the first terminal device 110 acquires a response message to the location message within a predetermined time (ex: 10 seconds), the first terminal device 110 repeats the process of transmitting the location message again (S106).

In this state, a case in which the first terminal device 110 does not receive a response message from the second terminal device 120 within a predetermined time may occur (S108). Then, the first terminal device 110 considers the second terminal device 120 to be out of the predetermined range and notifies the user through an alarm or the like so as to recognize the parent (S110). That is, it is recognized as a lost situation (s110).

Accordingly, the second terminal device 120 starts transmitting a location message indicating its location at a predetermined time period (S112). That is, the second terminal device 120 also corresponds to a condition for not receiving the location message from the first terminal device 110, so that the second terminal device 120 is changed to an operation mode for automatically transmitting the location message.

The location message periodically transmitted from the second terminal device 120 is received by the location recognition device 130 installed closest to the second terminal device 120 (s114). At this time, the location recognition device that receives the location message is changed according to the movement of the child (ie, the lost child) carrying the second terminal device 120. For example, if a child's movement is made in one straight direction, the position recognition device will receive a position message from the position recognition device located in front of the child's movement path. If moving straight backward after moving straight, one location recognition device receives the location message more than two times over time.

As the child moves, the location recognition device 130 transmits the location message received from the second terminal device 120 to the server 140 in real time (S116).

Then, the server 140 may acquire the movement path information of the second terminal device 120 based on the information received by the location recognition device 130 (S118). The obtained movement path information is transmitted to the first terminal device 110 (s120). In this case, the information obtained by the server 140 may not necessarily be movement path information. In other words, when Mia is still in one position without moving after being separated from the parent, only the location information where the Mia is located is obtained.

The first terminal device 110 displays the movement path information of the second terminal device 120 transmitted from the server 140 (s122). In this case, the movement route information may be displayed in text or in a state where the position or movement route information of the second terminal device 120 is mapped to the map information of the current region.

As described above, when the first terminal device 110 displays the movement route information until the missing terminal is found, steps 112 through 120 are repeated.

Meanwhile, the server 140 may display the missing occurrence notification information on a signage installed at a specific place (S124). This is to make the missing child more actively by the unspecified majority.

In addition to transmitting the location information of the second terminal device 120 to the first terminal device 110, the server 140 may be considered to allow the administrator to directly check the location of the second terminal device 120. have. This is to allow the management center staff in addition to the parent or guardian to quickly find the child carrying the second terminal device 120 while communicating with the manager.

Meanwhile, an example of displaying movement route information according to the present embodiment is illustrated in FIG. 4. 4, it can be seen that a specific area is divided into a plurality of zones. In the embodiment, the location recognition devices 130 are installed in the plurality of zones, respectively. Therefore, when the child moves away from the parent while carrying the second terminal device 120, the movement line can be easily understood. Looking at Figure 4 it is confirmed that the movement in the direction of the zone 6-> Zone 5>-> Zone 4-> Zone 7. On the other hand, in the case of the prior art with reference to Figure 4, when the specific area is included in one base station service zone (zone), it is not possible to determine in which place in the specific area the lost child.

As such, the embodiment of the present invention enables the parent carrying the first terminal device 110 to immediately check the moving line of the second terminal device 120 from the server 140 even if the child moves away from the child. You can quickly check the location.

On the other hand, in the present embodiment, the second terminal device 120 is fixed to the child's bag or clothes through the fixing device. If the second terminal device 120 is forcibly removed from the fixed device or powered off, the second terminal device 120 transmits a warning message to the location recognition device 130 to 130n or the server 140. Accordingly, when the child carelessly loses the second terminal device 120 possessed by him or herself, or is forcibly removed due to abduction or power off, the current child's position can be quickly determined.

In addition, among the position recognition devices 130 to 130n installed in a specific area, the position recognition device installed at the entrance side is located around the position recognition device at the current entrance side together with the location message if the second terminal device 120 is close at the time of the loss. A message informing that the message is located is transmitted to the first terminal device 110 and the server 140. Therefore, when the child is lost, it is easy to determine whether the child is within or out of the predetermined area where the location recognition device is installed.

As described above, in the present invention, when the parent and the child each carry a terminal device, when the child leaves a certain range from the parent, the location message is repeatedly transmitted from the child's mobile terminal device immediately and is installed in a specific place The recognition apparatus may transmit the location message transmitted from the child portable terminal device to the server in real time, and the server may process the location message transmitted to identify the moving line of the child and provide it to be displayed on the parent portable terminal device. . Therefore, parents can quickly cope with a lost child, especially by using their instincts to find a way or to find a parent, so that the child's movements can be closely tracked. Find a lost child.

Although described with reference to the illustrated embodiment of the present invention as described above, this is merely exemplary, those skilled in the art to which the present invention pertains without departing from the spirit and scope of the invention It will be apparent that other variations, modifications and equivalents are possible. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.

The present invention is able to grasp the movement of the child through the terminal device and the location recognition device installed in a specific place of the parent and child, it is possible to actively find the lost child in the early stage of the lost child, terminal for preventing children lost It is expected that the present invention can be applied to a device, a location recognition device for communicating therewith, and a related communication network field.
