In order to control the semiconductor fabrication and inspection equipment at a remote site, it may be necessary to monitor the video signals outputted from the semiconductor equipment in real time.

On the other hand, a method of remotely controlling an image of a computer screen by transmitting the image remotely is widely used for recent customer support, remote server management, and remote control in a commercial system. Such a device that remotely controls a computer is referred to as a remote control system (RCS). At this time, there are various ways to control the computer remotely.

In addition, in order to remotely control a remote computer or device in the local computer, it is necessary to transfer the image of the computer or device from the remote location to the local computer. The image of the remote site can be transmitted to the local computer through a normal Ethernet network. At this time, the image of the remote site can be compressed and transmitted to the local computer through the network.

However, in this case, a slight image loss may occur even when restoring according to the compression of the image. In addition, it may take time to compress and restore the image, and there may be a problem such as a time delay of the image.

Hereinafter, the present invention will be described in detail with reference to the drawings. Detailed descriptions of well-known functions and constructions that may unnecessarily obscure the gist of the present invention will be omitted.

In the present invention, a local control apparatus which is a non-compression transmission type remote image monitoring apparatus will be described as an example. However, the present invention is limited to a local control apparatus as a non-compression transmission type remote image monitoring apparatus It is not.

1 is a block diagram illustrating a remote computer 21 in a local computer 11 including a local control apparatus 40 as a non-compression transmission type remote image monitoring apparatus according to an exemplary embodiment of the present invention. The remote control system 1 can be monitored and transmitted in a systematic manner. FIG. 2 schematically shows the internal structure of the local control unit 40, which is included in the local computer 11 and is an uncompressed transmission type remote image monitoring apparatus.

Referring to the drawings, the local control apparatus 40, which is a non-compression transmission type remote image monitoring apparatus, includes a dedicated line remote control capture unit; Network interface; And a main control unit. The leased line remote control capture unit can receive the uncompressed image from the remote computer through the leased line. The network interface 200 may be connected to the outside through a network, and the main control unit connected to the network interface 200 may be connected to the outside via a network. The main control unit is connected to the network interface 200, and is connected to the dedicated line remote control capture unit, and controls the non-compressed image to be output to the monitor 13.

According to the present invention, it is possible to transmit the image of the remote computer 21 at the remote site to the local computer 11 easily accessible to the user) in an uncompressed manner. Thereby, the user can monitor the image of the remote computer 21 at the local computer 11 without time delay due to compression and / or restoration of the image.

At this time, the local computer 11 may be a computer such as a general-purpose PC (Personal Computer) which is commonly used. Accordingly, the general PC can receive the uncompressed image and allow the user to monitor the image of the remote computer 21 on the local computer 11 without delaying time due to compression and / or restoration of the image.

On the other hand, the leased line remote control capturing unit receives the uncompressed image from the remote computer 21 at a remote place through a private line, and can be a dedicated line remote control capture board 100 mounted on a commonly used general-purpose PC. At this time, the dedicated line remote control capture board 100 may be mounted in a card form in a local bus slot such as a peripheral component interconnect (PCI) of a PC or a peripheral component interconnect express (PCIe).

Here, a leased line is not a network like a normal Internet, but an uncompressed image can be transmitted. A cable such as an optical cable or a UTP cable can be applied. In addition, the network refers to a communication system such as a normal internet in which an image is compressed, transmitted, restored, and displayed on the screen. However, the present invention is not limited to this, and any connection method can be applied in which a leased line is transmitted in an uncompressed state without compressing an image and can be displayed on the screen without a separate restoration process.

Also, the main control unit may be a main board 300 mounted on a generally used general-purpose PC. Accordingly, the local computer 11 can be a general-purpose PC including the main board 300, and a general-purpose PC includes a dedicated-line remote-control capture board 100, and a general- The user can view the image of the remote computer 21 on the local computer 11 without a time delay due to the compression and / or restoration of the image by receiving the uncompressed image.

The local control apparatus 40 (hereinafter, referred to as an uncompressed transmission method remote image monitoring apparatus), which is a non-compression transmission type remote image monitoring apparatus according to an embodiment of the present invention, Compressed image through a dedicated line from a remote computer 21 at a remote place and outputs the uncompressed image to the main board 300 to be connected to the main board 300 via the main board 300, The remote control capture board 100 may be a dedicated line remote control capture board 100 for outputting an uncompressed image received from the monitor 13 to the monitor 13.

The local computer 11 is equipped with a network interface 200 and can be connected to a general-purpose network such as a general Internet through the network interface 200. Accordingly, the local computer 11 may be connected to a network and may be capable of outputting control signals through general Internet operations or the Internet. Accordingly, the non-compression transmission type remote image monitoring apparatus 40 receives the uncompressed image even in a general-purpose PC that can work on the Internet through a network, and receives the uncompressed image from the local computer 11 without a time delay due to compression and / To monitor the video of the remote computer 21.

At this time, the network interface card corresponding to the network interface 200 may be mounted on the local computer 11 as a card in a local bus slot such as PCI or PCIe of the PC. However, the local bus applied to the present invention is not limited to PCI or PCIe, and does not exclude the application of various other buses including ISA, EISA, and VESA.

However, the present invention is not limited to this, and the non-compression transmission type remote image monitoring apparatus 40 may be applied to the embodiment in which the network interface 200 is not installed in the local computer 11.

Meanwhile, in order to receive the uncompressed image through a dedicated line, a UTP cable (unshielded twisted pair cable) or optical cable may be used as a dedicated line, or a UTP cable and an optical cable may be used in combination. Although UTP cable is easy to install and convenient, it has a distance limitation to transmit images, and has a merit that relatively long distance transmission is possible in optical cable.

However, a non-compression transmission type remote image monitoring apparatus capable of monitoring an uncompressed transmitted image may be a dedicated apparatus such as a local station rather than a general-purpose computer. However, in this case, there may be a need for a local station, which is a separate dedicated equipment for the number of users.

At this time, a separate work space may be required by using a system composed of a separate hardware and monitor rather than a general PC type. In other words, the user should use the local station on the desk separately from the PC which he usually uses. In addition, when a network system and a dedicated line system are used in combination according to the situation, a remote control system has a disadvantage that a network system is used in a PC (local computer) and a dedicated line system is used in a separate local station. In such cases, it is impossible to integrate and operate the system.

On the other hand, a method of receiving an image for monitoring a computer image of a remote site may include a method of directly receiving a video signal through a dedicated line without compressing the image signal, and a method of compressing the compressed image to be received through a network.

In a method using a general network, images of a remote computer can be captured through a remote control device, compressed and transmitted to a local computer through a network. The local computer receives the compressed image data, restores the image, outputs it to the monitor, and inputs information such as a mouse and a keyboard to the remote control device through the network to control the remote computer. At this time, the remote control device may be configured with such a hardware module, or may be installed in a remote computer in a software manner.

At this time, since the method using a general network can be implemented in an existing Ethernet environment, it can be implemented at a low cost and the remote control system can be easily configured regardless of the location. In addition, with the development of recent network technology, high-speed equipment has been developed and high-quality images with higher resolution can be transmitted. However, despite the recent development of the technology, there may be a problem such as a minute image loss due to the compression of the image, a time delay of the image depending on the time required for image compression and restoration.

On the other hand, the method using a dedicated line can be used for sharing and controlling measurement images and medical images of equipment such as semiconductor / LCD / OLED / LED because it can have a high quality and clean image compared with an image compression method through a network have.

However, the terminal for confirming the image must be composed of a dedicated terminal such as a local station, and may be inconvenient in a recent computer control environment. However, in the non-compression transmission type remote image monitoring apparatus 40 according to the embodiment of the present invention, a dedicated line remote control capture board 100 is applied to a commonly used general purpose computer, It can be easily checked and controlled.

The image of the remote computer 21 is not compressed but is transmitted directly through a UTP cable or a dedicated line such as an optical cable. The input of the input device such as a keyboard or a mouse of the local computer 11 is also connected to a remote control device 30 (hereinafter, referred to as a dedicated line remote control device) which is a dedicated line remote control device by a dedicated line such as a UTP cable or an optical cable. And can be used for control of the remote computer 21. [ To this end, the leased line remote control capture board 100 may receive an input signal including a keyboard signal or a mouse signal, and may be transmitted to the remote computer 21 through a leased line. The internal structure of the dedicated line remote control device 30 connected to the remote computer 21 is schematically shown in Fig.

The leased line remote control device 30 can convert the uncompressed image output from the remote computer 21 into a video transmission signal that can be transmitted through a dedicated line such as a UTP cable or an optical cable for transmission. The video of the remote computer 21 may be output as an analog VGA or a digital DVI or HDMI signal. At this time, DVI / HDMI signals among the video signals input from the remote computer 21 need to be converted into TMDS (Transition Minimized Differential Signaling) signals or VGA signals into TMDS signals as analog signals.

The leased line remote control device 30 may include an A / D converter 311, a data selector 312, and a signal converter 313. The A / D converter 311 converts the VGA signal of the video signal input from the remote computer 21 into the TMDS signal. The data selector 312 selectively outputs the TMDS signal into which the VGA signal has been converted by the A / D converter 311 and the DVI / HDMI signal input with the TMDS signal. The signal converter 313 converts the TMDS signal output from the data selector 312 into a form that can be transmitted through a dedicated line such as a UTP cable or an optical cable.

At this time, the data selector 312 can selectively output a signal of a terminal from which a VGA signal is converted, and a signal from a DVI / HDMI signal input terminal that is input as a TMDS signal. When a DVI / HDMI signal input as a TMDS signal is input, a DVI / HDMI signal is output as a TMDS signal and an A / D converter 311 is output as a TMDS signal. When the TMDS signal through which the input VGA signal is inputted is inputted, the converted VGA signal can be outputted as the TMDS signal.

A keyboard or a mouse input input by the input device 12 of the local computer 11 may be transmitted through a dedicated line such as an optical cable or a UTP cable and input to the dedicated line remote control device 30. [ The dedicated line remote control device 30 can convert keyboard or mouse input to be transmitted into a keyboard or mouse signal and input the signal to the remote computer 21. Thus, the remote computer 21 can be controlled by the input device 12 of the local computer 11.

At this time, the user inputs an input such as a keyboard or a mouse through the input device 12 while watching a remote image displayed on the monitor 13 connected to the local computer 11 to control the remote computer 21 . To this end, the leased line remote control device 30 may include a keyboard / mouse converter 321 and a keyboard / mouse signal generator 322.

The keyboard / mouse converter 321 can convert a keyboard / mouse transmission signal transmitted through a dedicated line such as an optical cable or a UTP cable into a keyboard / mouse input signal that can be processed in the exclusive line remote control device 30. The keyboard / mouse signal generator 322 converts the keyboard / mouse input signal into a keyboard / mouse signal that can be processed by the remote computer 21 of the type that is output from the input device 22 and inputs the signal to the remote computer 21.

Therefore, the user can input the input such as the keyboard or the mouse through the input device 12 while watching the remote image displayed on the monitor 13 connected to the local computer 11 to control the remote computer 21 .

On the other hand, a leased line remote control device 30 is connected to the remote computer 21, and a local computer 11 is connected to the leased line remote control device 30 by a dedicated line. The remote computer 21 may be remotely located from the user. At this time, the user can directly operate the local computer 11 which is relatively easily accessible.

The user can control the remote computer 21 at a remote location through a leased line in the local computer 11 in the same manner as the local computer 21. At this time, the remote computer to be controlled may be a general computer such as a PC, but the present invention is not limited thereto and may be various electronic equipment including semiconductor manufacturing equipment. For this purpose, the dedicated line remote control device 30 may be equipped with a function of remotely controlling the remote computer 21 and / or the electronic equipment at the remote computer 11 in the local computer 11. [

On the other hand, a remote input device 22 is connected to the remote computer 21, and a control signal for controlling the remote computer 21 through the remote input device 22 may be input. At this time, the remote input device 22 may include a mouse and / or a keyboard connected to the USB terminal and / or the PS / 2 terminal. The monitor 23 is connected to the remote computer 21 so that an image output from the remote computer 21 through the video terminal Video can be displayed on the monitor 23.

The remote computer 21 may include input and output terminals such as a video terminal, a network terminal, and / or a USB terminal. The remote computer 21 is connected to the monitor 23 through a video terminal and can be connected to the input device 22 or the dedicated line remote control device 30 through an input / output terminal.

In addition, a camera is connected to the dedicated line remote control device 30 through a dedicated line to receive an image shot by the camera. Various network devices are connected to the leased line remote control device 30 through an additional network terminal, and input and / or output of additional control signals can be performed through the digital input / output terminal.

The remote computer 21, the remote input device 22, and the monitor 23 can configure the remote equipment 20 installed at a remote place. At this time, the remote equipment 20 may be mounted on a semiconductor device used for manufacturing a semiconductor, LED, LCD, or the like.

A local input device 12 is connected to the local computer 11 so that a control signal for controlling the local computer 11 through the local input device 12 can be input. At this time, the local input device 12 may include a mouse and / or a keyboard connected through a USB terminal and / or a PS / 2 terminal. A monitor 13 is connected to the local computer 11 so that an image output from the local computer 11 through a video terminal can be displayed on the monitor 13.

At this time, the remote computer 21 is connected to the dedicated line remote control device 30, and the local computer 11 is connected to the dedicated line remote control device 30, The remote computer 21 can be controlled remotely. At this time, the local computer 11 may be connected to the leased line remote control device 30 through a leased line. Further, the remote computer 21 remotely located can be remotely controlled by a control signal input through the local input device 12 through the mouse and / or the keyboard input to the local computer 11.

The local computer 11, the local input device 12, and the monitor 13 can constitute the local equipment 10. [ At this time, the user can remotely control the remote computer 21 installed remotely through the leased line remote control device 30 by operating the local equipment 10.

On the other hand, the remote input device 22 of the remote device 20 and / or the local input device 12 of the local device 10 may be connected to a mouse and / or keyboard as well as a trackball, a joystick, a button, a knob, It can be embodied as an input means specialized in various semiconductor devices that can control screens or semiconductor equipment remotely.

In this case, the control signal is generated by the input of an input means specialized in various semiconductor devices capable of remotely controlling a mouse and / or a keyboard as well as a trackball, a joystick, a button, a knob, a jog dial, Lt; / RTI >

A user operates the local input device 12 to generate a control signal for controlling the remotely located semiconductor equipment, and the generated control signal is input to the local computer 11. The local computer 11 appropriately converts the control signal input from the local input device 12 into a signal that can be transmitted through a dedicated line and transmits the signal to a remote location. The local computer 11 receives a status notification signal or a video signal of the semiconductor device 20 transmitted from a remote location and outputs the signal to a peripheral device of the local computer 11 or a monitor 13 of the local device 10 .

Here, the status notification signal may be an error signal of the semiconductor device, a current status monitoring signal of the semiconductor equipment, a response signal corresponding to a remote control command, or the like. A status notification signal may be displayed on the monitor 13 of the local equipment 10 to inform the user of the status notification signal more effectively or a lamp or a speaker may be provided to the local computer 11 to visually or audibly inform the user . However, the lamp or the speaker may be integrated into the local input device 12 or may be separately provided.

The remote equipment 20 and the local equipment 10 can exchange data through a dedicated line that can receive the image uncompressed. However, even if it is not a leased line, data can be exchanged by a general network or another wired network or wireless data communication. It is a matter of course that a communication protocol corresponding to each communication method can be used mutually in the remote equipment 20 and the local equipment 10. [

On the other hand, the local computer 11 can be connected not only to a private line but also to a general network. In this case, it is possible that an image in which a time delay due to compression or restoration may be a problem is transmitted in a non-compressed manner using a dedicated line, and a control signal or other monitoring signal without such a problem is transmitted through a general network.

FIG. 4 schematically shows an internal structure of a dedicated line remote control capture board 100 according to an exemplary embodiment of the present invention.

Referring to FIG. 1, a dedicated line remote control capture board 100 includes a signal converter 110 and converts an image transmission signal input through a dedicated line such as a UTP cable or an optical cable in a signal converter 110, 2 to 13). At this time, the image transmission signal input to the signal converter 110 is converted into an uncompressed image output from the remote computer 21 in the dedicated line remote control device 30 of FIG. 3 so as to be transmitted through a dedicated line such as a UTP cable or an optical cable The signal transmitted by the mobile station can be transmitted.

An input signal, such as a keyboard or a mouse, input from the input device (12 in FIG. 2) is input through the main board 300, and the exclusive-line remote control capture board 100 is transmitted through a UTP cable or a dedicated line such as an optical cable Possible keyboard / mouse transmission signals can be converted. To this end, the leased line remote control capture board 100 may include a keyboard / mouse processor 120 and a signal converter 110.

And can be converted into a keyboard / mouse input signal which can be processed in the dedicated line remote control capture board 100 by the keyboard / mouse processor 120. The signal converter 110 may convert a keyboard / mouse input signal into a keyboard / mouse transmission signal capable of being transmitted through a dedicated line.

Therefore, the user can input the input such as the keyboard or the mouse through the input device 12 while watching the remote image displayed on the monitor 13 connected to the local computer 11 to control the remote computer 21 .

FIG. 5 schematically shows an embodiment of a process in which an uncompressed image transmitted through a dedicated line in a dedicated line remote control capture board 100 is converted into an output image signal output to a monitor.

Referring to the drawing, a dedicated line remote control capture board 100 is a board mounted in a PC local bus slot such as a PCIe slot or a PCI slot of a local computer 11, and transmits image data transmitted through a dedicated line such as an optical cable or a UTP cable And transmits the image to the local computer 11 through the local bus of the PC, and the local computer 11 can receive the image and display it on the monitor 13 or the like. Accordingly, the leased line remote control capture board 100 can perform a leased line remote control function even in a general PC.

To this end, the leased line remote control capture board 100 may include a TMDS converter 111, decoders 112a and 112b, an image transmission unit 113, and a bus bridge 114. [ The TMDS converter 111 can convert an image transmission signal of an uncompressed image transmitted through a dedicated line into a TMDS signal. The decoders 112a and 112b can convert the TMDS signal into an RGB signal, for example, an RGB 24-bit signal.

The decoders 112a and 112b include a first decoder 112a for converting a TMDS signal into an RGB signal and a second decoder 112b for converting a TMDS signal into an RGB signal only when the resolution of the TMDS signal is larger than the reference resolution can do. Therefore, even when the TMDS signal is higher than the reference resolution, the TMDS signal can be converted into the RGB signal within a range that can be processed by the decoder.

The image transmission unit 113 may generate image data in accordance with the synchronization signal of the local bus to be connected to the main board 300 corresponding to the main control unit, and may transmit the generated image data to the bus bridge 114. At this time, a field programmable gate array (FPGA) may be used as the image transmission unit 113.

The bus bridge 114 allows the video data received from the video transmission unit 113 to be transmitted through the PCIe bus of the PC. The bus bridge 114 can perform a function of generating a signal and processing data in accordance with the PCI bus synchronization of the PC, in order to transfer data.

As shown in the drawing, a video signal input through a dedicated line such as an optical cable or a UTP cable is converted into a TMDS signal via a TMDS converter 111, and then converted into an RGB 24-bit signal via a decoder 112a and a decoder 112b . The decoders 112a and 112b can use only one of the first decoders 112a corresponding to the master when the TMDS signal has a resolution of 1920x1200 or less, for example. Since the TMDS signal is a dual DVI interface at a resolution of, for example, 2560x1600 that is higher than the reference resolution of 1920x1200, the first decoder 112a corresponding to the master and the second decoder 112b 2 corresponding to the slave Decoders 112a and 112b can be used together.

The RGB 24-bit signals output from the decoders 112a and 112b are sent to the main board 300 via the FPGA corresponding to the image transfer unit 113 and the PCIe bridge corresponding to the bus bridge 114. [ At this time, the function of the FPGA can transmit the image data to the PCIe bridge for receiving the RGB 24-bit image and delivering it to the PC. For this purpose, it is possible to generate a signal by adjusting the input RGB 24-bit image data to the synchronization of the PCIe bus. The synchronization signal may include HSYNC (Horizontal Sync.), VSYNC (Vertical Sync.) And Pixel Clock, and a data enable signal.

The main board 300 receives the video signal through the PCIe and stores it in the memory. The local computer 11 including the main board 300 can process the data through the device driver. At this time, the data is processed by an OS (Operating System) such as Windows (Windows) or Linux (Linux), and can operate in conjunction with an application program (Application S / W). With this function, a program running on a PC can receive an incoming image through a dedicated line such as an optical cable or UTP cable and display it on the screen.

FIG. 6 schematically shows a multiple connection configuration in which a plurality of remote computers 21 and a plurality of local computers 11 are connected in multiple using a switch system.

Referring to the drawings, the non-compression transmission type remote image monitoring apparatus can include a matrix switch 50 to construct a switch system capable of connecting a plurality of remote computers 21 and a plurality of local computers 11 in a multiplex manner have.

The matrix switch 50 is connected to a plurality of remote computers 21 as a dedicated line through a dedicated line remote control device 30 and is connected to a dedicated line remote control capture board 100 included in each of the plurality of local computers 11 And can control the connection of each of the dedicated line remote control capture board 100 and each of the dedicated line remote control devices 30.

In the case of a remote control system using a network, a plurality of local computers 11 connected to a network can freely access a plurality of remote computers 21 through a network device. In other words, computers connected to the network can access the space without restriction. In a method using a dedicated line, a switch system such as the matrix switch 50 is provided in the middle, so that a multiple connection environment can be configured. However, connection is possible only in a space where dedicated lines such as optical cables and UTP cables are installed.

In the case of a 1: 1 connection, only one local computer 11 and one remote computer 21 can be connected. However, if a switch system is configured in the middle, The computer 11 is connectable. The matrix switch 50 is a control device that receives a dedicated line such as a plurality of optical cables or a UTP cable and switches to a dedicated line such as a plurality of optical cables or UTP cables. At this time, it can be configured in the form of 32x32, 64x64, etc., and can be controlled by software.

The non-compression transmission type remote image monitoring apparatus according to an embodiment of the present invention can be connected to a network remote control system and can also operate as a local computer. By installing a dedicated line remote control capture board 100, It may also work. A plurality of connected network remote control systems and a dedicated line remote control system can be controlled at the same time, and can be managed in an integrated manner, so that a dual system can be conveniently operated. In addition, a separate local station becomes unnecessary, and space can be saved and used conveniently.

According to the present invention, it is possible to transmit an image of a remote site locally in an uncompressed manner, thereby monitoring an image locally without delaying time due to compression and / or restoration of the image.
