Remote control system and method of computer

The present invention uses a pair of unshielded twisted pair cable (UTP) cable to a remote control system of a computer that can transmit and extend the PS2 keyboard, PS2 mouse and sound signals and switch control signals up to 300M It is about.

In general, a computer remote control system is designed to control and manage a computer that is currently being used at a long distance.

That is, the remote control system can control and manage a computer located at a remote location based on one-to-one data communication between the computer and the computer, and can generate various imposing effects by installing a monitor and other peripheral devices at a remote location as needed. It is there to control and manage it.

However, such a remote control system is usually able to control a computer installed at a remote location based on one-to-one data communication between the computer and the computer, which has a problem that a computer must be installed at a remote place to control a peripheral device. .

In addition, by installing a computer in the management center and remotely installing a distributor and a plurality of display devices connected to the computer, a remote system that outputs and manages the video being played on a plurality of display devices installed remotely is simply a computer. Is only a device that outputs the image being played through the display device, in particular, there is a problem that each individual can not use or use the display device installed in a remote location.

Furthermore, a remote system that controls multiple display devices installed remotely as described above typically uses only three pairs of unshielded twisted pair (UTP) cables for the display device among the four pairs of unshielded twisted pair (UTP) cables. There was a problem of leaving a pair of unshielded twisted pair (UTP) cables without using them.

Therefore, the present invention allows the computer to transmit and receive data using only one pair of unshielded twisted pair (UTP) cables discarded among the four pairs of unshielded twisted pair (UTP) cables connecting the computer to each other. It is intended to be able to perform various tasks through peripheral devices installed in remote places based on large computers.

That is, in order to achieve the above object, the present invention provides a pair of data transmitters and receivers capable of transmitting and receiving data between a computer and a peripheral device, and at the same time, a pair of unshielded twisted pairs (UTPs) through the data transmitter and receiver. Using only the cable, the signal from the keyboard, mouse and power switch can be converted into direct data for transmission and reception.

Therefore, in the present invention, a pair of data transmitters and receivers can be installed between a computer and a peripheral device for connecting the computer, thereby enabling various operations to be performed through information input and output at a remote location, and at the same time controlling the power of a computer installed in a management center at a remote location. There is a characteristic.

In addition, the present invention can transmit a signal input and output using only one pair of unshielded twisted pair (UTP) cable of the four pair of unshielded twisted pair (UTP) cable connecting the data transmitter, the computer and peripherals It does not require a separate communication cable to connect.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In describing the operating principles of the preferred embodiments of the present invention in detail with reference to the accompanying drawings, when it is determined that detailed descriptions of related well-known functions or configurations may unnecessarily obscure the subject matter of the present invention, the detailed descriptions thereof will be made.

As shown, the remote control system of a computer according to an embodiment of the present invention, an unshielded twisted pair (UTP) cable 50 between a computer main body 10 installed in a management center and a peripheral device 20 installed at a remote location. It is installed including a pair of data transmitters 30 and 40 connected to each other.

Here, the data transmitter 40 connected to the main body of the computer is connected to the mouse port and the keyboard input port of the main body of the computer, and is connected to the sound output port of the main body to simultaneously receive and transmit analog signals and digital signals. It is supposed to be.

Here, another data transmitter 30 installed at a remote location is the same as the data transmitter 40 of the computer main body installed at the management center, and the PS2 mouse 21, the PS2 keyboard 22, and the speaker 24 and Directly connected to the power switch 23 is to transmit the input signal to the data receiver 40 of the computer body located in the management center. In this case, the data transceiver is operated by receiving power from an internal battery or externally.
Here, the unshielded twisted pair (UTP) cable 50 connecting the data transmitter 40 of the management center and the data transmitter 30 of the remote place uses only one pair of unshielded twisted pair (UTP) cables out of a total of four pairs. It is possible to transmit and receive data, and in particular, it is limited to a maximum of 300M in consideration of noise on the cable.

In addition, the data transmitter 30 receives the digital signals of the PS2 keyboard and the PS2 mouse and the switch control signal of the power switch 23 from the input / output ports 31 connected to the PS2 keyboard 22 and the PS2 mouse 21 and the like. A pair of unshielded twisted pairs (UTPs) are combined by a microprocessor 32 for receiving and converting serial data signals, and a time-division method of the converted serial data signals and the analog sound signals inputted and outputted through the sound input / output unit 33. It includes a transmission and reception driver 35 for transmitting to another data transmitter and receiver 40 located in the management center through the).
In addition, the transmission and reception driver 35 includes a power shift unit LEVEL SHIFT for converting the potential of the received signal to restore the serial data signal and the analog sound signal.

Herein, the microprocessor (converter) receives two pulse digital signals inputted from each PS2 type keyboard and mouse and switch control signals of the power switch 23 that are clicked on, and is inputted through a total of five input / output lines. It is processed as one serial data signal and transmitted to the timing controller.

The timing controller is configured to transmit the serial data signal input from the microprocessor and the analog sound signal input through the sound input / output unit to form a complex signal in a time division method (TDMA) and transmit it to the transmission and reception driver.

The transceiving driver amplifies the composite signal input and output and simultaneously modulates and demodulates the signal to a predetermined signal potential to transmit or receive the signal.
