Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an interface device,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an interface device and an interworking system of a terminal and a computer using the same, and more particularly, to an interface device for interfacing a terminal and a computer using Bluetooth wireless communication.

Recently, with the advent of mobile terminals such as smart phones and tablet computers, it has become possible to store and process information without regard to time and space, and to exchange information with other data processing devices using various communication methods.

In particular, mobile terminals are small, portable and easy to use, have a wide variety of applications, and are widely used in everyday life because the applications are installed easily. In addition, due to the development of various types of wireless communication, it is possible to operate other connection devices or share information stored in the mobile terminal by using the mobile terminal by linking the mobile terminal and the other connection device through wireless communication.

  Among them, Bluetooth wireless communication refers to a short range wireless technology standard for exchanging information by connecting portable devices having a Bluetooth module to each other. It is used when low-power wireless connections are needed in very short distances, typically around 10 meters.

Bluetooth uses the ISM (Industrial Scientific and Medical) frequency band of 2400 ~ 2483.5MHz. In particular, since the same frequency band as that of various systems is used, interference may occur between systems. To prevent this, Bluetooth adopts a frequency hopping method. Frequency hopping is a technique for quickly moving a large number of channels according to a specific pattern and transmitting the packets (data) little by little. Bluetooth hopes 1600 times per second to the assigned 79 channels. This hopping pattern must be synchronized between the Bluetooth devices before the communication is established. That is, Bluetooth is configured as a master and a slave between devices, and the slave device is synchronized with the frequency hopping generated by the master device to allow communication between the two devices. This synchronization process is called pairing (pairing two devices together). Therefore, if the pairing is not performed, the communication between the devices is not performed.

The Bluetooth wireless communication is performed between devices having a Bluetooth module. Therefore, when a device that does not support Bluetooth wireless communication is used as a master device, a Bluetooth relay device is used, and most of the Bluetooth relay device has a form similar to a USB interface, which is called a USB DONGLE .

Accordingly, a USB dongle is used to link a computer having no Bluetooth module and a mobile terminal having a Bluetooth module.

1 is a schematic diagram showing an interworking system between a computer and a terminal using a general USB dongle.

1, the terminal 10 includes a Bluetooth antenna 12 and a pairing module 14. The computer 30 includes a USB port 32, a pairing module 34, an operating system 38, And the USB dongle 20 includes a Bluetooth antenna 22 and a USB connector 24 for transmitting and receiving information signals.

When the two devices are interlocked using the USB dongle 20 for Bluetooth wireless communication, the pairing between the computer 30 and the terminal 10 must be performed. The computer 30 transmits and receives a signal of the terminal 10 via the Bluetooth antenna 22 of the USB dongle 20 and receives the device search signal and device connection signal for pairing from the USB dongle 20 to perform pairing .

Even if Bluetooth wireless communication is performed using the USB dongle 20, pairing must be performed for each device to be connected. That is, if the pairing between two devices is not set, the pairing operation must be performed in order to perform Bluetooth wireless communication.

1, when the signal standards supported by the terminal 10 and the computer 30 are different, a program 36 for converting a signal to be processed by the computer 30 must be installed in the computer.

That is, when an application 18 for generating a mouse signal using the moving distance information relative to the terminal 10 is installed and the cursor or the arrow of the computer 30 is to be operated by the application 18, The mouse signal is transmitted according to the SPP (SERIAL PORT PROFILE) standard 16 but the computer 30 can not process the signal according to the standard. Thus, the computer 30 must be provided with a program or device 36 for converting a signal that can be processed by a computer, for example, into a mouse signal according to the HID (Human Interface Device) standard.

If the signal standard supported by the terminal 10 and the signal standard that can be processed by the computer are different even if the USB dongle 20 is used, a signal conversion program or device must be separately installed in all the computers to be used There is a hassle.

Referring to FIG. 2, an interworking system 1 of a terminal and a computer includes a terminal 10 and a computer (not shown) when transmitting an information signal of the terminal 10 including a Bluetooth module to the computer 200 via Bluetooth wireless communication. The terminal 10 and the computer 200 are interlocked with each other without pairing.

Generally, when an information signal is transmitted / received through Bluetooth wireless communication, an apparatus for inputting an information signal, for example, a terminal 10 and an apparatus for processing an information signal, for example, a computer, should be paired with each other. However, according to the present invention, the terminal 10 and the interface device 100 are paired with each other, so that the terminal 10 and the computer 200 can be interlocked with each other without pairing with the computer 200 that processes the information signal. Accordingly, the terminal 10 can transmit / receive information signals to / from the computer using the interface device 100 paired with the terminal 10 without any other pairing with the computer 200 that processes the information signal.

Specifically, the interworking system 1 between a terminal and a computer includes a terminal 10, an interface device 100, and a computer 200.

As shown in FIG. 2, the terminal 10 can output an information signal to the outside through Bluetooth wireless communication. The terminal 10 includes a Bluetooth module, and includes a Bluetooth antenna 12 for short-range wireless communication, and a pairing module 14 for storing pairing information of the terminal 10 and performing pairing.
