Description

Missing device and method using Bluetooth {STUPID CHILD PREVENTION APPARATUS AND METHOD USING BLUETOOTH}

The present invention relates to an application technology of Bluetooth, and in particular, by adding an anti-loan function to a Bluetooth terminal to generate an alarm when the infant is out of the communication range of the terminal, the apparatus and method of anti-loan using Bluetooth to prevent the occurrence of the missing child It is about.

Bluetooth is a technology that allows wireless devices to send and receive voice and data by connecting wirelessly portable devices such as portable PCs and mobile phones at low cost within a narrow range.

For example, when Bluetooth technology is implemented in mobile phones and laptops, you no longer need to use the cumbersome cables that are currently used to connect mobile phones and laptops, making devices free from cables, as well as existing data networks and peripherals. It provides a universal bridge that forms a special group between interfaces between devices and devices remote from the fixed network infrastructure.

In addition, because it is designed to operate in a noisy radio frequency environment, Bluetooth uses fast recognition and frequency hopping to avoid interfering with other signals and to deliver faster and shorter packets compared to other systems operating in the same frequency band. It is configured to send and receive data stably.

Therefore, the present invention was created in order to use the Bluetooth protocol as described above, by registering the ID of the counterpart terminal to communicate with the user's terminal and confirms whether or not to communicate with the counterpart terminal at regular intervals, the interval between the two terminals It is an object of the present invention to provide an anti-lost device and a method using Bluetooth to prevent the occurrence of a child by attaching the terminal to the infant by causing an alarm if communication does not occur outside this predetermined distance.

Hereinafter, an embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing the configuration of an anti-lost device using Bluetooth. As shown in FIG. 1, a microprocessor, a codec, a vocoder, and a main processor (MSM) that implements an interface function for mobile communication are provided on a single chip. Mobile Station Modem 10; A Bluetooth link manager 20 configured to configure and set a Bluetooth link, encrypt a Bluetooth link, and the like; A Bluetooth signal controller 30 for controlling each unit for signal processing and smooth function performance of the terminal using a Bluetooth protocol; A Bluetooth radio transceiver 40 for transmitting and receiving radio signals in a frequency range (2.402 GHz to 2.480 GHz) usable by Bluetooth; A data storage unit 50 for storing ID information of the counterpart terminal to be communicated with; An alarm generating unit 60 for generating an alarm when it does not communicate with the counterpart terminal; A direction detector 70 for detecting a direction of communication with the counterpart terminal; And an information display unit 80 for displaying information such as the ID and the last communication direction of the counterpart terminal which has lost communication.

First, the present invention is characterized in that the mobile terminal further adds a function for finding an ideal partner using a Bluetooth protocol, or can independently configure a terminal having the above function.

Here, the Bluetooth link manager 20 and the Bluetooth wireless transceiver 40 play a role of establishing a link between terminals and transmitting / receiving a radio frequency so that wireless communication can be performed at a short range (10 cm to 10 m) using a Bluetooth protocol.

Next, the data storage unit 50 inputs the ID, communication cycle, and alarm sound information of the counterpart terminal.

That is, when there are a lot of counterpart terminals, each terminal can be distinguished by its ID, and when the communication period between terminals is short, power consumption of the terminal is high, so that the communication period can be appropriately adjusted according to the situation.

Next, the alarm generating unit 60 serves to generate an alarm when it does not communicate with the counterpart terminal, and emits a light emitting device according to a mode set in the Bluetooth signal control unit 30 or the data storage unit ( The alarm sound stored in 50) is output or the terminal is vibrated.

Next, the Bluetooth signal controller 30 controls each component of the terminal according to the user's setting, and communicates with the terminal in close proximity at regular intervals to compare and determine whether the information of the user and the opponent match. Do this.

Next, the direction detecting unit 70 detects the direction of communication with the counterpart terminal, and measures the electric field strength and the like when each terminal communicates with each other to determine the final communication direction of the terminal whose communication is lost based on the information. Allow me to measure.

Therefore, the more terminals, the more accurate the direction detection can be.

Next, the information display unit 80 serves to display the information of the counterpart terminal that has lost communication at the same time as generating an alarm in the alarm generating unit 60, the ID of the terminal that has lost communication and the direction detecting unit ( The direction of the counterpart terminal measured in 70) is displayed.

In this case, the ID of the terminal may be output only as a number, but the name or title may be output by mapping the child's name or title so that the user can easily recognize the ID.

In addition, depending on the setting of the direction detecting unit 70, the distance can be determined by measuring the electric field strength from the counterpart terminal. It is obvious that an alarm may be issued to give caution.

In addition, if all the above functions are added to all the terminals, the volume becomes large. Therefore, all of the above functions are added to the terminal (main terminal) carried by the parent, and the ID of the other terminal (sub terminal) for possessing the child is own. Only parts for transmission can be attached to reduce volume and cost.

Then, the method for preventing the occurrence of the missing by the device having the above-described technical configuration will be described with reference to the flowchart of FIG.

As shown in the figure, once a user registers an ID and a communication cycle of a counterpart terminal to communicate with his terminal, an alarm sound generated when the communication is lost (S11).

In this case, a plurality of IDs that can be registered in the main terminal may be registered according to the number of sub terminals, and the sub terminal may register only its ID.

Accordingly, the terminal communicates with the counterpart terminal every predetermined communication period. That is, the signal communication cycle is checked (S12), and when the communication cycle is reached, communication is sequentially performed according to the ID registered in the data storage unit 50 (S13).

Next, if communication with all the registered ID is possible, continue the communication process every predetermined time (S14), if the communication is disconnected and displays an ID of the corresponding terminal on the information display unit 80 and generates an alarm ( S15).

As described above, the apparatus and method for preventing the loss of children using Bluetooth according to the present invention have an effect of preventing the occurrence of the lost child by generating an alarm when the secondary terminal is separated by a certain distance from the parent.

In addition, the present invention has an effect that can be prevented when the secondary terminal is attached to a bag or an important portable article to be used.
