Description

Wired and wireless interfacing apparatus for computer

The present invention relates to a wired / wireless connection device, and more particularly, to a device capable of connecting a computer to a peripheral device by wire and wirelessly.

In general, in a workplace where many employees work, several computers are shared by one printer, and a wired connection device such as a router is used for this purpose. In addition, all computers used in the workplace are connected to a network through a wired connection device called a hub.

As such, the conventional wired connection device for connecting a computer to a printer or a network generally has a shape as shown in FIG.

As shown in FIG. 1, the conventional wired connection device includes a main body 11, one port 12 for connecting to a printer or a network by a connector, and several computers by the connector. Ports 13 to 18 to be connected to.

Here, the ports 12 to 18 are made up of a parallel port (Parallel Port), USB (Universal Serial Bus) port or RS-232C port, but only the same type of port.

However, in the case of the conventional wired connection device as described above, only connectors of the same type can be used, so that connectors or the like having different signal systems cannot be used.

Also, in recent years, as the wireless communication technology is rapidly developed, a method such as a blue tooth that transmits and receives data wirelessly with a peripheral device is also used in a computer. Because of this, it could not be applied to the wireless access method. In addition, in the case of a computer capable of wireless and wired connection, there is a problem in that a large cost is required because a wireless connection device and a conventional wired connection device must be provided respectively.

Accordingly, an object of the present invention is to provide a wired / wireless connection device that can significantly improve practicality by connecting wired and wirelessly between a computer and a peripheral device.

In addition, another object of the present invention is to provide a wired / wireless connection device capable of connecting a signal input through a port having a different signal system from a port to which a computer is connected to a computer.

(21 to 23) to the wired device, and the signal received from the wireless device through the transmission and reception processing unit 27 is connected to the computer through the first to third output ports (24 to 26), and from the computer First to third Connection control unit 28 for connecting the signal transmitted through the output port (24 to 26) to the transmission and reception processing unit 27, and receives the signal input from the wired device or the wireless device through the connection control unit 28 and temporarily It has a memory 29 for storing.

The first input port 21 and the first output port 24 are USB ports.

The second input port 22 and the second output port 25 are RS-232C ports.

The third input port 23 and the third output port 26 are parallel ports.

In addition, the wired / wireless connection device of the present invention is not limited to the USB port, the RS-232C port, and the parallel port, but may be attached to other signal systems.

The first and third input ports 21 to 23 may be connected to various wired devices that can be connected to a computer by wire, such as a keyboard, a mouse, a printer, and a network.

The computer is selectively connected to any one of the first to third output ports 24 to 26.

In the case of inputting, it can be connected to a computer through the wired / wireless connection device of the present invention. Here, the computer may wirelessly transmit the processing result of the information and command input from the wireless device to the wireless device through the wired / wireless access device of the present invention.

Referring to the operation of the wired or wireless connection device of the present invention as described above in detail.

When a computer is connected to the first output port 24, which is a USB port, a signal is input from the wired device through the second input port 22, which is an RS-232C port, or the third input port 23, which is a parallel port. The connection control unit 28 converts the signal input through the RS-232C port or the parallel port having a different signal system from the USB port into a signal suitable for the signal system of the first output port 24, which is a USB port, and then the signal. Is transmitted to the computer through the first output port 24, which is a USB port.

As such, when a signal is input through a port having a different signal system from a port to which the computer is connected, the connection controller 28 converts the signal into a signal suitable for the signal system of the port to which the computer is connected and transmits the signal to the computer.

When a radio frequency signal is wirelessly received from the radio device through an antenna, the transmission / reception processing unit 27 converts the radio frequency signal into a signal of a band suitable for the connection control unit 28 and transmits it to the connection control unit 28. Subsequently, the connection control unit 28 converts the signal into a signal suitable for the signal system of the port to which the computer is connected, and transmits the signal to the computer.

When a signal to be transmitted from the computer to the wireless device is input to the connection control unit 28, the connection control unit 28 transmits the signal to the transmission and reception processing unit 27. Subsequently, the transmission / reception processing unit 27 converts the signal transmitted from the connection control unit 28 into a radio frequency signal and transmits the signal to the wireless device through an antenna.

As described above, the computer is connected to an external wired device and a wireless device, and if a plurality of signals are simultaneously input from the outside, the connection controller 28 transmits a signal input from the outside to the computer through the following process. do. However, the process of transmitting the signal to the computer by the connection control unit 28 is as described above.

While the signal input through the first input port 21 is being processed by the computer, if a signal is wirelessly received from the wireless device through the antenna, the connection controller 28 sends this signal to the memory 29 for a predetermined time. Save it. At this time, when the processing of the signal input through the first input port 21 is terminated in the computer, the connection controller 28 transmits the signal stored in the memory 29 to the computer.

As such, during processing of a specific signal in a computer, if a signal is input to a port or wirelessly different from the port to which the signal is input, the connection controller 28 stores the signals in the memory 29 and then stores the signals in the computer. Upon completion of signal processing, the signals stored in the memory 29 are transferred to the computer in the order of input.

As described above, the wired / wireless connection device of the present invention is not limited to a computer and can be applied to various wired devices and wireless devices that are connected to peripheral devices by wire or wirelessly.

Although the technical idea of the present invention has been described in detail according to the above preferred embodiment, it should be noted that the above embodiment is for the purpose of description and not for the limitation.
