Description

[0001] PORTABLE DEVICE FOR MISSING CHILD PREVENTION [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a portable device for preventing a child, and more particularly, to a portable device for preventing a child from being lost due to mutual communication between a guardian and a protected person.

As outdoor activities increase, the number of children who lose their children is steadily increasing. It is because of the crime of kidnapping the child with incomplete security, or when the guard is glancing for a moment in a crowded place such as an amusement park, the child is getting distracted from the guardian.

The Mia case is very unlikely to be solved if the property deviates a certain distance from the place where the child left the caregiver. According to one study, if a mia goes beyond 200 meters from its original location, the probability of finding a child is very low in a short period of time. If it is outside the boundaries of a clear-cut area like an amusement park, the chances of regaining the child become very low.

There has traditionally been an effort to maximize the likelihood of misbehavior by promptly searching for the situation before the child has accrued and before the child has largely disappeared. In addition, since it is difficult to find a child by the efforts of a parent alone, various techniques have been proposed to enable cooperation in the search for lost children.

The first is to give children accessory items such as a child-resistant necklace or a child-resistant bracelet. By printing the name of the child and the contact information of the caregiver in these accessories, it is intended to enable the child or the police to seek help effectively when the child is lost. However, this method is helpful only after the child or the police perceives that the child is in difficulty by asking for help in the surrounding situation in the specific case, and since it is not helpful in the previous stage, Is clear. Furthermore, there is a problem in that it is not helpful at all if the child moves along with the third person without any signs as in the child abduction case.

The second is to use announcements in amusement parks. When a guardian who has lost a child requests a guardian to broadcast, the amusement park control center informs the gender, age, dress, etc. of the child through the announcement so that visitors or management personnel in the amusement park can find the child. However, it is not so easy to find the lost child with only the rough information provided through the announcement because there are too many children of similar age and costumes at the amusement park. In addition, this measure has a limited role in that it can be operated only in a limited area where the control center is constructed like an amusement park.

The third option is to notify parents of the risk of childbirth by allowing the guardian and the child to carry their handsets and to sound an alarm when they are out of range. This scheme simply provides information that the guardian and the child have fallen over a certain distance. In the case of an amusement park or a picnic, the guardian and the child often fall off a certain distance. In addition, this measure has no clear role to play in finding children or cooperating with others in situations where a child is actually lost.

There have been various attempts to prevent or deal with the MIA case, but none of them have been sufficient.

Korean Registered Utility Model No. 0377234 (Registered: February 21, 2005, Name: Wireless alarm for preventing two-way losers)

The present invention provides a handheld device for preventing an outbreak of a malfunction, in which a slave terminal possessed by a protected person is alerted to a remote from the master terminal when the slave terminal moves away from the master terminal by a predetermined distance .

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same components are denoted by the same reference symbols whenever possible. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

FIGS. 1 to 3 are block diagrams illustrating a portable device for preventing a child according to an embodiment of the present invention. The portable device for preventing a child can include a slave terminal 100 and a master terminal 200.

Here, while the slave terminal 100 and the master terminal 200 are turned on, the slave terminal 100 and the master terminal 200 are continuously connected to each other through short-distance communication.

It is obvious that the slave terminal 100 and the master terminal 200 operate through the built-in battery units 110 and 210 and the detailed description of the battery units 110 and 210 will be omitted.

The master terminal 200 is protected by a guardian to prevent misbehavior and the slave terminal 100 is carried by a protected person who is protected by a guardian possessing the master terminal 200 and the guardian is connected to the slave terminal 200 via the master terminal 200 100 can be easily judged and protected.

2, the slave terminal 100 includes a beacon generating unit 120, a first voice communication unit 130, a voice output unit 140, and a control unit 150. [ The slave terminal 100 can operate the power via the master terminal 200 so that it can not operate the on / off operation of the power on the protected side.

If the slave terminal 100 is operated by the protected person, if the power of the slave terminal 100 is turned off due to a malfunction or intention of the protected person, communication with the master terminal 100 is no longer possible.

The beacon generator 120 has unique identification information and generates a beacon signal. At this time, the beacon generator 120 continuously broadcasts the beacon signal to the master terminal 200 with the predetermined radio wave intensity when the power of the slave terminal 100 is ON.

The first voice communication unit 130 transmits or receives voice information according to a predetermined frequency.

The voice output unit 140 outputs voice information received through the first voice communication unit 130 to the outside. This allows the caregiver to directly ask for help from nearby people, and even those who can not call for help can easily ask for help around them.

The control unit 150 controls the voice information transmitted to the first voice communication unit 130 or the voice information output to the voice output unit 140.

Although not shown in FIG. 2, the slave terminal 100 may further include a coupling unit so that the slave terminal 100 can easily carry it.

At this time, the engaging part (not shown) may be formed in a clock shape so as to be worn on the wrist of the protected person, or may be in the form of a tongue for medal in clothes or a bag.

3, the master terminal 200 includes a beacon receiving unit 220, a distance measuring unit 230, a second voice communication unit 240, a voice output unit 25, a display unit 260, (Not shown).

The beacon receiving unit 220 receives the beacon signal according to the unique identification number. At this time, it is preferable that the master terminal 200 receives the beacon signal of one or more designated slave terminals 100.

The distance measuring unit 230 analyzes the beacon signal received by the beacon receiving unit 220 and measures the distance from the slave terminal 100. [ That is, the intensity of the received beacon signal is measured and the distance to the slave terminal 100 is measured according to the intensity.

That is, different weights are assigned to the intensity of the beacon signal, and the closer the distance is, the higher the weight is, and the lower the weight is, the longer the distance is.

The distance measurement method includes a Received Signal Strength Intensity (RSSI) method using a received signal strength, a TOF (Time of Flight) method using a time taken for a signal to be transmitted between devices, and a TDOF (Time Difference of Flight) method, an AOA (Angle of Arrival) method using an arrival angle of a radio wave, and a POA (Phase of Arrival) method using an arrival phase of a radio wave.

Of these, TOF and TDOF schemes, also called RSSI scheme, TOA (Time of Arrival) and TDOA (Time Difference of Arrival), are mainly used for distance measurement.

The second voice communication unit 240 transmits or receives voice information to the first voice communication unit 130.

The voice output unit 250 outputs a warning related to an alarm or a misplaced event when the distance between the master terminal 20 and the slave terminal 100 is longer than a predetermined distance.

The display unit 260 outputs information necessary for a guardian such as a distance from the slave terminal 100, a current setting state of the master terminal 200, and the like.

The control unit 270 controls the threshold distance to the slave terminal 100 by adjusting the reception intensity of the beacon receiving unit 220 and processes the voice information received from the second voice communication unit 240 to output the voice output unit 250 so that the predetermined voice information is output to the audio output unit 250 and controls the display unit 260 so that the guardian can easily grasp the situation with the slave terminal 100 .

A method in which the master terminal 200 and the slave terminal 100 are respectively operated by a guardian and a protected person are as follows.

When the power of the slave terminal 100 is turned on by using the master terminal 200, the slave terminal 100 periodically transmits a beacon signal of a predetermined intensity to the master terminal 200.

When the master terminal 200 receives the beacon signal, it means that the protected person possessing the slave terminal 100 is located in the vicinity. If the slave terminal 100 is out of the predetermined distance, the master terminal 200 is weak The master terminal 200 recognizes that the slave terminal 100 is out of the predetermined distance through one signal and gives a notification message to the guardian through the voice output unit 250 of the master terminal 200. [

The protector may be moved to the display unit 260 where the distance from the slave terminal 100 is outputted through the distance measurement unit 230 of the master terminal 200 and may be detected by the second voice communication unit 240 To the slave terminal 100 so that the protected person can listen to the voice information.

Accordingly, the present invention has the effect of searching for a protected person as soon as possible by notifying the guardian when the protected person is separated from the guardian by a certain distance.

In addition, although the present invention notifies the caregiver that the guard is separated from the guard, the guardian can search for the guarded person while narrowing the distance due to the distance from the guarded person.

In addition, since the present invention is not linked to a communication company, the cost required for each month is reduced, and the cost is reduced.

The above-described portable device for preventing the lost child is not limited to the configuration and the manner of operation of the embodiments described above. The above embodiments may be configured so that all or some of the embodiments may be selectively combined to make various modifications.
