[0001] The present invention relates to an integrated personal computer (PC)

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an all-in-one (AIO) personal computer (PC) having a network separation function, and more particularly, To an integrated personal computer having a network separation function for simplifying an interface with an external network PC and quickly switching the network through a high speed hub switching method.

In general, an integrated personal computer called AIO refers to a large-sized (19-inch or larger) LCD display and a PC component integrally manufactured using components for a notebook personal computer. AIO PCs take up less space and consume less power.

The prior art for AIO PC has been disclosed in the following Patent Document 1: Korean Utility Model Publication No. 20-2013-0002680 (published on Mar. 03, 2013).

The prior art disclosed in Patent Document 1 has a structure in which two computers and one liquid crystal display are installed in combination, and one computer is connected to an internal network (LAN) and the other computer is connected to an external network (WAN) , And a completely independent operating system.

Meanwhile, the communication environment using a computer such as the Internet is rapidly expanding, and a self-networking network for building an internal system is installed and mutual settlement and data transfer are performed by networking. If such networking is networking such as a military unit or a nuclear power plant that requires national security, there is a fear of intrusion of a hacker. Especially, if a hacker breaks into a national defense network and causes an error or malfunction such as a missile control, it means a fatal damage to national defense. In addition, even if a customer breaks into a financial institution, if a customer withdraws the deposit unfairly, it also causes a catastrophic damage to the computer system and a decrease in reliability of the customer. In order to prevent such a system damage, it is recommended to separate the external network and the internal network and use two separated computers for internal network and external network.

For example, a first computer including a monitor, a keyboard, a main body, and a LAN card using an internal network (LAN network); And a second computer including a modem using a monitor, a keyboard, a main body, and an external network (Internet network), and selects a corresponding computer according to each desired network.

However, in such a case, each individual is equipped with two computers, and the computer must be selected and used according to need, which is inconvenient to use.

Therefore, in order to solve the inconvenience of such use, a network switching computer is developed and put into practical use so that the network switching can be facilitated.

And disclosed in the following Patent Document 2: Korean Patent Laid-Open Publication No. 10-2011-0088981 (Published on Aug. 4, 2011).

The prior art disclosed in Patent Document 2 includes a contact point selected from among a first contact for disconnecting the connection between the internal network and the external network, a second contact connected to the internal network, and a third contact connected to the external network, A signal changeover switch to be connected; An ad-hoc control unit for transmitting a switching signal to the signal changeover switch using the received control signal; A network switching computer is implemented by an interface processor that converts data between the signal switching switch and the main board into a PCI system or a USB system and transmits an LAN card control signal received from the main board to the LAN card controller.

The integrated personal computer having the network separation function according to the preferred embodiment of the present invention includes an internal network dedicated computer (PC1) 100, an external computer 200, a keyboard 10, and a mouse 20.

The internal network dedicated integrated computer 100 includes an internal computer device 120 installed in the main body 101 and including a main board and a plurality of input / output peripheral devices for a built-in internal network dedicated computer, and performing network switching control; A display panel 110 for displaying images of the internal computer device 120 and an external network computer 200 connected to the external network; A network switch 140 for generating a network switch signal in response to a user operation; A KVM (Keyboard / Video / Mouse) board 130 which is embedded in the main body 101 and interworks with a mainboard scaler included in the main board of the internal computer device 120 to switch the display / keyboard / mouse / ); And an HDMI input port 150 for receiving HDMI data (video, audio) of the external computer 200.

Here, instead of the physical network switch 140, a dedicated network switch dedicated hot key may be used on the keyboard.

In addition, the integrated network-only integrated computer 100 may further include a beep sound adjustment switch 160 for the user to arbitrarily adjust the level of the network switch beep sound. It is also possible to use such a tone control switch 160 as a separate physical switch, but in another embodiment of the present invention, a network switch tone control hotkey previously designated to the keyboard may be used. Here, the sound volume control switch 160 can use a slide volume switch.

2, the internal computer device 120 includes a main board 121 for controlling the entire operation of the internal network dedicated integrated computer 100 and controlling display and audio output of an image during network switching, An input / output (I / O) peripheral device 122 connected to the main board 121; And a main board scaler 123 for controlling switching of the display / keyboard / mouse / sound in conjunction with the KVM board 130. Here, the input / output peripheral device 122 preferably includes a peripheral device such as an ODD, a card reader, and a web cam.

As shown in FIG. 3, the KVM board 130 includes a HID USB 131 for individually controlling connection of a HID (Human Interface Device) input device; A USB hub (HUB) switch 133 for connecting the HID input device and the internal network dedicated computer 100 or the external network computer 200 according to the network switch control signal; A hub device 132 for controlling connection between the HID USB 131 and the USB hub switch 133; And controls the switching of the USB hub switch 133 according to a network switching signal generated by the network switching switch 140 or a hotkey for switching the network of the keyboard, Lt; RTI ID = 0.0 > 134 < / RTI > Here, the HID input device may include a keyboard 10 and a mouse 20.

The operation of the integrated personal computer having the network separation function according to the preferred embodiment of the present invention will be described in detail as follows.

The internal network dedicated integrated computer 100 includes a KVM board 130 formed in the form of a board inside the main body 101 for easily connecting the external network computer 200 and performing network switching quickly and conveniently, . Here, since the KVM board 130 is in the form of a board, it is not necessary to occupy a lot of space. Particularly, when the main body 101 is vertically mounted at a predetermined position of the main body 101, it takes up less space and space efficiency can be improved. In addition, since only the signal cable terminal of the external network computer and the video and audio data cable terminal are connected to the integrated network-dedicated computer 100, the cable complexity can be remarkably reduced in comparison with a method of connecting a plurality of existing external cables, The number of connection terminals is small and the convenience of the user can be improved. In addition, since the number of cable terminals to be connected is small, the durability of the product can be improved as compared with the conventional cable connection method.

In a state where the KVM board 130 is installed in the internal network dedicated integrated computer 100, the user connects another computer using the external network to the integrated network dedicated integrated computer 100, And an external network. Here, the internal network means an internal network such as a LAN, the external network means an external network such as the Internet, and the external network computer means an APIM mini personal computer, a tablet PC, and the like.

In order to connect the external network computer 200 connected to the external network to the internal network dedicated computer 100, the data interface connection terminal is connected to the USB hub switch (not shown) of the KVM board 130 provided at the predetermined position of the main body 101 133). An HDMI cable is connected to the HDMI input port 150 provided at a predetermined position of the main body 101 for the HDMI data interface of the external network computer 200.

When the external network computer 200 is connected to the internal network dedicated integrated computer 100 in this manner and the computer is used using the keyboard 10 and the mouse 20, The keyboard 10 and the mouse 20 are connected to each other and the internal computer device 120 in the main body 101 is connected to the internal network. That is, the hub device 132 in the KVM board 130 transmits the signal input through the keyboard 10 and the mouse 20 connected to the HID USB 131 to the USB hub switch 133. At this time, the USB hub switch 133 is in a state of connecting the keyboard and the mouse to the internal computer device 120 under the control of the KVM controller 134 linked to the mainboard scaler 123 of the internal computer device 120 Connected to PC1). Then, a video signal generated according to the operation of the internal computer device 120 is displayed on the display panel 110, and a voice signal is transmitted through a connected speaker or earphone. Here, the initial state in which the external network computer 200 is connected is regarded as an internal network connection state, and the keyboard 10 and the mouse 20 are considered to be connected to the internal network dedicated computer 100.

Next, when the user selects an external network using the network switch 140 or the network switch hotkey pre-designated on the keyboard to use the external network, the network switch signal is transmitted through the KVM controller 134 to the internal computer device 120 to the main board scaler 123 of the main board. The main board scaler 123 transmits the transferred network switching status signal to the main board 121, and the main board 121 receiving the switching status signal performs network switching control.

As a part of the network switching control, the network switching control signal generated from the main board 121 is transmitted to the KVM controller 134 linked through the main board scaler 123. The KVM controller 134 controls the USB hub switch 133 in accordance with the network switch control signal transmitted from the internal hub switch controller 134b so that the USB hub switch 133 is connected to the external network computer 200 and the HID USB 131 and the HID input device (keyboard and mouse) connected thereto. In the present invention, a USB hub switch is used as a switch for network switching. This enables smooth network switching without buffering and rapid network switching. In particular, when the USB hub switch is used as the network switch, the user can obtain control of the keyboard and mouse from the desired network PC at a desired timing. That is, when the user selects the external network through the network switch 140 or the hotkey for switching the network using the keyboard and simultaneously uses the keyboard 10 and the mouse 20, 200, so that the external network can be used quickly.

When the external network computer 200 is connected to the internal computer device 120 to switch the network, the video and audio data generated from the external network computer 200 according to the operation of the user's keyboard 10 and the mouse 20 And is input to the HDMI input port 150 provided at a predetermined position of the main body 101 through the HDMI cable. The video and audio data transmitted from the external network computer 200 through the main body 101 is displayed on the display panel 110 through the main board scaler 123 and the audio is transmitted through the connected speaker or earphone . Thus, the user uses the external network computer 200. As described above, the external video and audio sources are simply received and processed through the HDMI interface with the external network computer 200.

In another aspect of the present invention, when the network is switched, a beep indicating that the network is switched can be generated by adjusting the volume level selected by the user.

For example, when network switching is performed, the network switch signal controller 134c of the KVM controller 134 detects the operation state of the signal tone control switch 160 or a dedicated hot key for signal tone control previously set on the keyboard, To control the network switch signal. As is well known, the beep adjustment switch 160 can use a slide volume switch. The volume control consists of three levels: High, Medium, and Low. In the present invention, the volume control level is set to three levels such as high, middle, and low. However, the present invention is not limited to this, and it is also possible to further divide the volume control level to set a volume level of many levels.

When a specific volume level is selected, the network switch signal adjuster 134c adjusts the level of the beep volume through the pulse width modulation control method, and the adjusted signal is transmitted to the outside through the speaker. Therefore, the user recognizes that the network switching has been performed through such a tone.

The user can freely select the beep level as described above, and the user can use the beep tone suitable for the environment in which he / she works because of the beep level control function. For example, if your work environment is a very quiet environment, such as an office or a library, the network switch tone level is set to the lowest level to prevent others from being disturbed by the network switch tone. In addition, when the working environment of the user is a working environment in which ambient noise is largely generated, the network switching signal level is set to the highest level, thereby preventing the user from hearing the network switching signal due to the ambient noise.

Although the present invention has been described in detail with reference to the above embodiments, it is needless to say that the present invention is not limited to the above-described embodiments, and various modifications may be made without departing from the spirit of the present invention.

The present invention is applied to a computer system technology for conveniently connecting an external network computer using an integrated network dedicated internal network and conveniently switching the internal network and the external network.
