Description

[0001] The present invention relates to a wearable Bluetooth device,

The present embodiment relates to a child-proof prevention system using a Bluetooth device.

The number of childbirths is increasing, and it often occurs in multipurpose facilities in the order of large mart (30.5%), amusement park (14%) and terminal (5%) (Source: Socio-economic cost analysis , Korean Social Welfare Studies, Vol. 61, No. 2).

The social costs for missing children are increasing, and an average of 770 million won per person can be spent. According to research papers, 34.12% have experienced child missing, and the most common way to find disappearances is by myself. However, in the early stage of the disappearance, the mental damage of the protector and the missing child is large, and it is difficult to respond appropriately early. The most important thing in preventing the disappearance of children is how to prevent them in advance, and what actions are taken in the first 10 minutes is very important.

Therefore, there is a need to introduce a device that can be easily used at any place, and can prevent the child from being lost by providing an alarm corresponding to the distance between the guardian and the guardian who do not need maintenance costs.

Of course, there have been proposed various types of miso prevention systems in the past. For example, Korean Patent Registration No. 10-1375111 and the like have been provided with an anti-sickness prevention system using a smartphone, and various anti-sickness prevention systems using various Zigbee or Bluetooth communication have been studied.

However, these technologies usually use a communication short-circuit as a switching medium within the Bluetooth communication range, and the moment when a misbehavior occurs is a distance outside the Bluetooth communication, There is a problem.

Especially, when there is no radio interference or external communication like underground space, or when GPS reception is not smooth, the GPS installed on the child side may not provide any help.

Korean Patent Publication No. 10-2003-0065014 (published on Aug. 2003)

The present embodiment provides a child-proof prevention system using a wearable Bluetooth device capable of calculating the distance between a child and a management terminal even in a place where GPS reception is impossible, and capable of freely transferring bidirectional voice information when necessary.

The child-proof prevention system using the wearable Bluetooth device according to the present embodiment includes a management terminal having a child-proof application driver installed with a GPS and a Bluetooth transmission / reception module; And a client terminal having at least one of a GPS sensor, an acceleration sensor, and a gyro sensor, and operating with battery power capable of Bluetooth transmission / reception with the management terminal, , The GPS coordinates, and the acceleration sensor signal to detect whether the client terminal is out of the safety distance of the wearer, and when the distance of the client terminal is out of the predetermined reference distance, And a two-way communication is possible.

The client terminal further includes a GPS module, and can transmit the current position coordinates of the client terminal when requested by the child-proof application driver.

The client terminal may further include at least one of a microphone, a lamp, and a speaker unit.

The client terminal may be any one of a button arrangement, a wrist watch, a necklace, a bracelet, a hat, and a hair band as a wearable device.

The first to third warning signals may be simultaneously output through a speaker unit installed in the management terminal and the client terminal in the form of a voice or a sound effect.

The first reference distance may be 30 m, the second reference distance may be 60 m, and the third reference distance may be 100 m.

The loss prevention application driving unit may calculate the distance direction and the departure speed with respect to the client terminal using the Bluetooth communication signal strength of the client terminal and store the data in a predetermined memory.

When the client terminal deviates from the third reference distance, the loss prevention application driver may store at least one of a final position, a final direction, a final movement speed, and a final ambient noise at a final departure time.

When the client terminal deviates from the third reference distance when the client terminal has the GPS function, the child-proof application driver may output the final position and the moving direction of the client terminal from the management terminal using an arrow or the like.

The anti-malware application driver can grasp the position and the moving direction of the client terminal using only the Bluetooth signal of the client terminal.

For example, it can be seen that the management terminal finds the most distant and near distance using the signal strength with the client terminal among the trajectories moving in a circle of 3 ~ 4 m, and the client terminal is positioned on the extension line. The strength of the Bluetooth signal with the client terminal according to the movement of the management terminal can be output from the speaker of the management terminal in a loud manner. In addition, when the GPS coordinates of the management terminal can be used, the final position and the moving direction of the client terminal can be outputted on the map using an arrow or the like.

When the client terminal deviates from the third reference distance, the child-proof application driver uses a speaker installed in the client terminal to deliver a command to the wearer to transmit a voice message requesting to stop the current position .

The anti-malware application driver can grasp the position and the moving direction of the client terminal using only the Bluetooth signal of the client terminal.

In addition, the child-proof application driver may determine that the management terminal finds the most distant and near distance from the locus of movement of 3 to 4 meters using the signal strength with the client terminal, and determines that the client terminal is located on the extension line It is also possible to do.

In addition, the child-proof application driver may output the strength of the Bluetooth signal with the client terminal according to the motion of the management terminal, in a loud manner from the speaker of the management terminal.

In addition, when the GPS coordinates of the management terminal can be used, the child-proof application driver may output the final position and the movement direction of the client terminal using an arrow on the map displayed on the display of the management terminal .

In addition, when the speed of the wearer of the client terminal deviates from a predetermined reference speed by using any one of the RSSI value change of the client terminal, the GPS and the acceleration sensor signal, the loss prevention application driver transmits an alert signal and converts it into a call mode can do.

When the client terminal is managed by the management terminal and the client terminal is periodically searched for within the specific range, the management terminal can be switched to the voice call request mode to the client terminal .

When the management terminal searches the client terminal, the malware prevention application driver obtains the MAC address or the device name and the received signal strength (RSSI) value of the client terminal when retrieving the client terminal, When the management terminal changes from the management terminal to the voice call request mode, the client terminal automatically accepts the connection and changes the state of the two-way voice communication channel Can be connected.

It is possible to calculate the distance and the relative position using the Bluetooth signal strength without the help of the GPS because the distance between the child wearing the wearable Bluetooth device and the management terminal can be easily calculated even in a place where reception of the GPS signal is difficult have.

It is possible to present the position of the missing child in the management terminal with an approximate arrow, and it is possible to grasp the position of the missing child more easily through the management terminal.

Since a plurality of wearable Bluetooth terminals can be registered in the management terminal, even if one teacher, such as a kindergarten or a children's house, cares for a plurality of children, it is possible to output a stepwise alarm by distance or speed with respect to client terminals Therefore, it is possible to prevent the occurrence of the lost child in advance.

In addition, even if the child or guardian disappears from the field of view, the mutual voice communication is possible through the two-way voice communication in the Bluetooth radio receiving range, thereby preventing the child from being embarrassed or frightened, You can tell them not to move so they can find it, or you can tell them to move to the place you are at.

In another embodiment, a smartphone or a dedicated transceiver of a tourist guide and an ear transceiver of a tourist can transmit one-to-many unidirectional voice, and if necessary, a certain tourist can transmit voice to the guide.

At this time, the management terminal 100 may further include a GPS module for locating the current management terminal 100 together with the Bluetooth transmission / reception module. When the terminal is configured as a general dedicated terminal rather than a smart phone, A speaker, a GPS and a Bluetooth transmission / reception module need to be installed.

2, when the management terminal 100 according to the present embodiment is provided as a smart phone, the management terminal 100 includes a communication module 104, a memory 106, an input unit 108, A display unit 110, a speaker 112, a vibration motor 114, a lamp 116, a Bluetooth module 118, a prevention application driver 120, and a GPS.

The communication module 104 is a communication module for telephone communication using a communication company such as 2G, 3G, 4G, etc., and can be used for voice telephone communication and data transmission / reception.

The memory 106 stores various information calculated by the anti-theft application driver 120. In the memory 106, the position of the client terminal 200 calculated by the anti-aversion application driver 120, Data such as a direction, a moving speed, a final position, a final direction, a final peripheral noise, a final moving speed, and the like can be stored for each client terminal 200.

The input unit 108 may be a keypad or a separate input unit. In recent years, the display unit 110 may be configured as a touchable display panel and configured as a virtual keyboard or a touch input unit.

The display unit 110 may be a display panel, a liquid crystal display capable of touch screen, or the like. The display unit 110 may display the user interface of the child-proof application driver 120 and display the relative position of the currently registered client terminal 200 with the management terminal 100 as a center.

For example, as shown in FIG. 1, the client terminal 200 outputs the management terminal 100 at the center and displays the first to second reference distances a, b, and c concentrically, Can be displayed using points or the like. Also, if necessary, it is also possible to largely output the position change of the client terminal 200 by using arrows or the like.

According to the control signal of the anti-theardage application driving unit 120, the speaker 112 can output different first to third warning signals according to the first to third reference distances a, b, and c, Effect or the like. For example, when the client terminal 200 is out of the first reference distance a, a small sound is output. When the client terminal 200 is out of the third reference distance c, a very loud sound is emitted for a relatively long time Can be output.

The vibration motor 114 vibrates the first to third warning signals according to the first to third reference distances a, b, and c in accordance with the control signal of the anti- Output. For example, the vibration motor 114 may change the frequency of the first to third warning signals, change the vibration period, or feel the difference as the vibration intensity. For example, when the client terminal 200 is out of the first reference distance a, a weak vibration is output. When the client terminal 200 is out of the third reference distance c, a very strong vibration is output for a relatively long time Can be output.

According to the control signal of the anti-theft application driver 120, the lamp 116 outputs different first to third warning signals according to the first to third reference distances a, b, and c, Lt; / RTI > For example, the lamp 116 may vary the number of blinks of the first to third warning signals, and may control the flicker period or the brightness difference.

The client terminal 200 may be provided as a wearable device. The client terminal 200 may include a Bluetooth module 210, a microphone 221, a speaker 222, a vibration motor 230, a GPS 240 and a lamp 250, as shown in FIG. 2 .

The Bluetooth module 210 is for exchanging Bluetooth communication with the management terminal 100. The control signal of the child-proofing application 120 may be transmitted through the blue boot module 210. [

Under the control of the management terminal, the microphone 221 can record ambient noises and the like, and can freely communicate with the management terminal using the Bluetooth module 210 when necessary. When the second reference distance B is deviated, the microphone 221 starts operating according to an operation command of the anti-aliasing application 120, records ambient noise or the like, 260) and can switch to a mode in which mutual free communication is possible. The stored surrounding noise or voice call content may be transmitted to the management terminal 100 through the Bluetooth module 210. [

According to the control signal of the anti-theardage application driver 120, the speaker 222 outputs different first to third warning signals according to the first to third reference distances a, b, and c, Effect or the like. For example, when the client terminal 200 is out of the first reference distance a, a small sound is output. When the client terminal 200 is out of the third reference distance c, the sound is output for a relatively long time can do.

The vibration motor 230 vibrates the first to third warning signals according to the first to third reference distances a, b, and c in accordance with the control signal of the anti- Output. For example, the vibration motor 114 may change the frequency of the first to third warning signals, change the vibration period, or make the wearer of the client terminal 200 feel the difference as the vibration intensity. For example, when the client terminal 200 is out of the first reference distance a, a weak vibration is output. When the client terminal 200 is out of the third reference distance c, a very strong vibration is output for a relatively long time Can be output.

The GPS 240 stores the current position coordinates of the client terminal 200 in the memory 260 in real time. Since the GPS 240 is capable of transmitting and receiving radio waves only in the outdoors, it may be excluded from the selection option of the client terminal 200 when the indoor living and use is mainly performed. Therefore, the GPS 240 can be mounted on the product or installed on the main PCB in a mounting option structure of the GPS chip, so that the client terminal 200 can be configured as an optional function.

According to the control signal of the anti-theft application driver 120, the lamp 250 outputs different first to third warning signals according to the first to third reference distances a, b, and c, Lt; / RTI > For example, the lamp 250 may vary the number of blinks of the first to third warning signals, and may control the flicker period or the brightness difference.

Meanwhile, the client terminal 200 may be any one of a button arrangement, a wrist watch, a necklace, a bracelet, a hat, and a hair band as a wearable device.

Hereinafter, the operation of this embodiment will be described using the flowchart of FIG.

When the malware-preventing application driver 120 of the management terminal is executed, the controller 102 controls each component to perform a necessary series of operations (S10).

The distance between the client terminal 200 and the management terminal 100 is calculated by using the signal sensitivity according to the distance change between the client terminal 200 and the management terminal 100, (S20).

1, the child-proof prevention application driving unit 120 is divided into a safety zone A, a warning zone B, and a warning zone C, 200 in the mobile communication terminal. At this time, the safe area A can be managed as the first reference distance a, the attention area B as the second reference distance b, and the warning area C based on the management terminal 100.

The child-proof application driver 120 periodically calculates the relative position of the client terminal 200 with respect to the management terminal 100. If the client terminal 200 is out of the first reference distance a (S30 , And may output a first warning signal to the speaker 222 of the client terminal 200. At this time, as described above, the management terminal 100 can also output the same first warning signal (S40).

The child-proof application driver 120 calculates the relative position of the client terminal 200 with respect to the management terminal 100 in step S20, and if the client terminal 200 determines that the second reference distance b is equal to or greater than the second reference distance b, The user can output a second warning signal to the speaker 222 of the client terminal 200. [ At this time, as described above, the management terminal 100 can also output the same second warning signal (S60).

The child-proof application driver 120 calculates the relative position of the client terminal 200 with respect to the management terminal 100 in step S20. If the client terminal 200 determines the third reference distance c, (S70), a third warning signal may be output to the speaker 222 of the client terminal 200. [0050] FIG. At this time, as described above, the management terminal 100 can also output the same third warning signal. At this time, at the time of sending the third warning signal, it is possible to output a previously stored voice signal. For example, it is instructed to move to a specific position such as a directive indicating no further movement at the current position, A phrase, or a continuous phone number of a leader or a guardian, etc. (S80).

The first reference distance a may be 30 m, the second reference distance b may be 60 m, and the third reference distance c may be 100 m. However, the present invention is not limited to this, and it is also possible to increase or decrease the distance according to the Bluetooth communication signal environment. Also, in the above-described embodiment, warning signals are output between the management terminal 100 and the client terminal 200 through a total of three reference distances, but the above steps may be increased or decreased as needed. For example, it may be subdivided into five or more steps, or it may be possible to simply form the reference distance in only one step. This can vary as much as the system needs.

In addition to the above-described embodiment, in addition to the above-described embodiments, the MAC address or the device name of a plurality of client terminals can be registered in the management terminal to periodically search the client terminal. MAC address or device name already registered within the setting range during search When a client is not searched, a voice message or a voice call channel can be connected. One manager, such as a child's home, a kindergarten, and a lower elementary school, can efficiently manage the prevention of childbearing of a plurality of supervised infants and children.

In particular, bidirectional communication can be performed using the Bluetooth communication module. Therefore, it is also possible for the instructor or the manager to send an instruction command or the like directly by voice using the anti-theft application driver 120 within a certain distance. That is, when the sudden increase in the speed of the client terminal 200 or the first to third reference distances a, b, and c is deviated, the anchorage prevention application driver 120 manages the danger signal To the terminal 100 and / or the client terminal 200, and immediately enters the bidirectional communication mode, thereby making it possible to make an emergency call between the management terminal 100 and the client terminal 200. [

For example, when the speed of the client terminal 200 is equal to or less than a predetermined speed, the anti-theft application driver 120 may use any one of the RSSI value change of the client terminal 200, When the reference speed is exceeded, the warning signal can be transmitted and the communication mode can be forcibly switched to the two-way communication mode. Of course, this operation is manually switchable.

Particularly, in the case of bidirectional communication, since it is possible to freely talk within the range of the Bluetooth radio wave without a separate base station, it can be used in an underground space in which it is difficult to receive the signal of the base station. In particular, since there is no need to use a communication base station, clear voice exchange is possible without expenditure of a separate communication cost. That is, in general, when using a voice channel in Bluetooth communication, one to many calls are impossible. However, in the case of the present invention, a voice call can be performed using a data channel, so that multiple calls can be made simultaneously.

In addition, compared with the conventional anti-blind system using Bluetooth or Wi-Fi signal, existing technologies can not take any other action until the moment the wireless signal such as Bluetooth is disconnected. However, in the case of this embodiment, Since the terminal 200 is managed, when the management terminal 100 moves in the direction of the place immediately before the occurrence of the lost child, it is immediately possible to grasp the position of the client terminal 200 as soon as the client terminal 200 enters the communication range.

In addition, even if the GPS signal can not be confirmed, even if there is no GPS function in the indoor space, when the client side deviates from the field of view, it is instructed not to move to the client terminal side, The relative position and direction of the fixed client terminal can be calculated using the signal detection such as the intensity of the Bluetooth signal, and the relative position and direction of the client terminal 200 can be tracked without the GPS.

Meanwhile, in the above-described embodiment, a technique of sensing the relative position and direction of the client terminal 200 using the strength of the Bluetooth signal has been described, but the present invention is not limited thereto. To reduce the error range, If possible, they may be used in parallel.

In addition, information such as position information, moving speed and direction of the client terminal 200 can be recorded in the memory 106 in real time, You can quickly find your location.

The embodiments of the present invention described above and shown in the drawings should not be construed as limiting the technical idea of the present invention. The scope of protection of the present invention is limited only by the matters described in the claims, and those skilled in the art will be able to modify the technical idea of the present invention in various forms. Accordingly, such improvements and modifications will fall within the scope of the present invention as long as they are obvious to those skilled in the art.
