Therefore, it is becoming a big issue to manage computers safely and to provide endless services.

Such a computer makes the system operable by an operating system called an OS, and the user executes an application program installed in the operating system to process and store information.

Also, in the field of industry, it can be seen that many operations are performed by the computer itself without the help of the human on the stable basis of the computer operating system. Looking at several industries, in the mobile industry, each base station for sending radio waves has an unmanned system that is not managed by people, and there are a myriad of ATMs in the bank that are not managed by people. All of these systems have an operating system installed, and in case of problems with the installed operating system, they fall into an environment that does not provide normal services.

In the conventional method, when a problem occurs in the system, a method of controlling the power supply at the remote place and restarting the system is mainly used. However, no matter how stable the operating system is, it can be seen many times that the virus enters the operating system or the system becomes unbootable. In such a case, even if the system is rebooted, it is in a situation that the problem can not be solved, so that the manager has to visit the remote site for repairing, which causes a serious problem in the service.

The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. It is provided to let you know. Therefore, the embodiments described in the present specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and are not intended to represent all of the technical ideas of the present invention. Therefore, various equivalents It should be understood that water and variations may be present.

1 is a conceptual diagram illustrating a configuration of a remote restoration system of a computer system according to an embodiment of the present invention.

As shown in FIG. 1, the remote restoration system of the present invention commands the remote computer 100, connects to the manager computer 200 at the remote computer 100, receives the command, and reboots the remote computer 100 Or restores the operating system of the remote computer 100.

At this time, in the process of delivering the command from the administrator computer 200 to the remote computer 100, a command is transmitted from the administrator computer 200 to a network device connected to the remote computer 100 via the Internet or a network device connected to the outside, At this time, the command transmitted to the network may be transmitted to the remote computer 100 through a communication method that can be recognized by the remote computer 100 from a device built in the remote computer 100 or an external device, ) In a recognizable memory.

When the remote computer 100 is rebooted, the command transmitted from the manager computer 200 is analyzed by the master boot record (MBR), the BIOS, the UEFI, and the like. When the restoration command is transmitted from the manager computer, And then boot the operating system for restoration of the storage device storing the restoration program.

In this case, the program for restoration is stored in a storage device or an external storage device to which the remote computer 100 boots, and when the restoration command is issued from the remote computer 100, the boot order is changed to the restoring program that stores the restoration program, Booting from the built-in boot device or external storage device, and then restoring the system safely. The execution of the program for restoration may be determined by the master boot record (MBR) of the system, or may be determined by BIOS or UEFI built in the system.

Also, the master boot record (MBR), the BIOS, or the UEFI can receive commands from a remote location via a wired or wireless network to determine whether to execute the program for restoration. However, in the Master Boot Record (MBR), BIOS, or UEFI, there is a very limited way to communicate with the remote location, so additional communication equipment can be added to perform communications over wired and wireless networks.

In addition, the entire restoration program may be stored in a master boot record (MBR), a BIOS, or a UEFI to form a single system.

In addition, when receiving a command transmitted from a remote location in the master boot record (MBR), BIOS, or UEFI of the restoration program, a USB keyboard signal or a PS2 keyboard signal or a serial communication (COM Port) is transmitted The remote command can be received.

Also, when receiving a command transmitted from a remote master by a master boot record (MBR), BIOS, or UEFI of the restoration program, a device mounted inside or outside the computer records the command in a part of the system storage device or memory, (MBR), BIOS, or UEFI.

The process of booting the restoration area operating system will be described in detail below.

If the command transmitted from the administrator computer 200 is an instruction including automatic restoration (S800), the operating system of the remote computer is restored with the image designated by the administrator computer 200 or designated by the remote computer 100 S900). At this time, in the process of restoring the operating system of the remote computer 100, the restored image can restore the operating system of the remote computer 100 from the images stored in the manager computer 200 or the third network storage device and other storage devices.

FIG. 2 is a flowchart illustrating a method of receiving a command transmitted from a manager computer 200 to a network through a MBR, a BIOS, a UEFI, or a third boot loader, through a keyboard input It is schematized to receive the command.

As shown in FIG. 2, the data transferred from the administrator computer 200 via the Internet is configured to perform a desired operation when the remote computer 100 boots through the remote booting unit 300.

FIG. 3 is a block diagram illustrating the configuration of the remote booting unit in FIG. 2 in detail.

3, the remote booting unit 300 includes a keyboard control unit 320 including a USB hub and a keyboard controller, a relay control unit 330 including a relay, a communication and control unit 330 including a microcomputer and Ethernet, (310), which are largely composed of three modules.

At this time, the communication and control unit 310 stores commands transmitted from the administrator computer 200 through the Internet, and controls the relay control unit 330 and the keyboard control unit 320 to execute commands.

The keyboard control unit 320 receives commands transmitted from the communication and control unit 310 to the relay control unit 330 and transmits the commands to the remote computer 100 through keyboard input. That is, when two specific lines are connected, the key control unit 320 transfers the key value corresponding to the combination of the two lines to the remote computer 100 through the USB hub or directly to the USB port of the remote computer without going through the USB hub.

The relay controller 330 transmits a command for keyboard input to the keyboard controller 320 and controls the power of the remote computer 100 by controlling the reset or power button of the remote computer. That is, a function of connecting a specific line to the keyboard control unit 320 through the relay is performed.

Accordingly, the administrator computer 200 interprets commands transmitted to the communication and control unit 310 and determines which two lines of the keyboard control unit 320 are to be connected by the communication and control unit 310 Specify. At this time, if the two lines to be connected are specified, the communication and control unit 310 can specify which relay should be controlled.

In this way, in the communication and control unit 310, a command for operating a specific relay is transmitted to the relay control unit 330, so that the relay operates. At this time, the specified two lines of the keyboard control unit 320 are connected due to the operation of the relay, and the key value specified by the MBR or the BIOS / UEFI is transmitted from the output unit of the keyboard control unit 320. [

3 is a diagram illustrating a method for issuing a command when a remote computer is booted in the administrator computer 200. The configuration illustrated in this figure may be changed according to a communication method. In addition, the communication and control unit 310 may be integrated into a microcomputer including a communication unit, and the keyboard control unit 320 may also be implemented in software.

Therefore, the above configuration does not necessarily have to be implemented in hardware, but it can be implemented in software. This is a natural consequence of the development of technology.

As shown in FIG. 4, when restoring the remote computer 100, it is possible to selectively designate whether to restore the operating system of the remote computer 100 or to restore the entire disk. That is, since the operating system for restoring the remote computer 100 is stored in a separate space of the restored program storage device, the entire original disk of the remote computer 100 can be completely restored even if restored after initialization.

At this time, even if the system is configured by the above-described restoration method, if the disk for booting the remote computer 100 is physically damaged, the remote computer 100 may not be able to recover the remote computer 100 The same problem occurs that the disk of the remote computer must be replaced. Therefore, in order to solve the above problem, two disks can be mirrored using a raid device, but there is a disadvantage that separate hardware must be mounted in a PCI slot for raid configuration. Most embedded systems do not have a PCI slot or are used all at once, so it is often difficult to configure a raid environment in a limited environment such as an embedded system.

Therefore, the present invention can completely solve the above problem by attaching the boot disk selection device 110 to the remote computer 100, as shown in FIG. That is, by using the boot disk selection device 110, the power or data line of the boot disk 101 mounted on the remote computer 100 is blocked by the remote computer 100 and recognized as the spare disk 102 .

At this time, after the spare disk 102 is connected to the boot disk, the administrator computer 200 issues an operating system restoration command or automatically restores the operating system to the spare disk 102 newly installed in the remote computer 100, The system can be safely restored.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It will be apparent to those skilled in the art that various modifications may be made without departing from the scope of the present invention. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
