Abstract

A bag using bluetooth is provided to prevent the bag from being lost or stolen by using a terminal using bluetooth to the bag. A bag using bluetooth comprises a main processor, a bluetooth link management unit, a bluetooth signal control unit, a bluetooth wireless transceiver, a data storage module for storing the ID information of a terminal, an alarm generation unit, a direction detection unit, and an information display unit for displaying the information such as the ID of the opponent terminal and the final communication direction in case of the interception of communication.

Description

Bag using Bluetooth {bluetooth Gabang}

Attaching a Bluetooth chipset to a bag using Bluetooth communication, the phone will emit an alarm when it is separated by a distance from the user.

Bluetooth is a technology that allows voice and data to be sent and received by wirelessly connecting portable devices, mobile phones and other portable devices within a narrow range at low cost.

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 common bridge between interfaces between devices and devices that are remote from 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 interference with other signals and uses faster and shorter packets compared to other systems operating in the same frequency band. It is configured to send and receive data stably.

The present invention has been created to use the Bluetooth protocol as described above to register the ID of the other terminal to communicate with the user's terminal and to check whether or not the communication with the other terminal at regular intervals, the interval between the two terminals a certain distance It provides an anti-lost bag using Bluetooth that attaches the terminal to the bag and prevents the bag from being lost or stolen.

In general, an anti-lost device is provided with a transmitter in a notebook or a wallet, and attaches a receiver to a user's body so that a predetermined warning sound is generated from the receiver when the transmitter is separated by a predetermined distance. Therefore, the purpose is to minimize the loss of portable items.

The Bluetooth link management unit and the Bluetooth wireless transceiver transmit and receive link settings and radio frequencies between terminals so that wireless communication can be performed at a short range (10 cm to 10 m) using a Bluetooth protocol.

The alarm generator is responsible for generating an alarm when communication with the counterpart terminal is not made. Depending on the mode set in the Bluetooth signal controller, alarm sounds or vibrations are made.

The information display unit not only generates an alarm sound but also displays information on the bag, and indicates the direction of the bag where communication is lost.
