As such, when the connection element of the input unit 40 is implemented as a stereo jack, an installation space may be secured as compared with the case where the connection element of the input unit 40 is implemented as a modular jack.

The network connection unit 10 includes a first connection unit 11 to which a LAN cable connected to an internal network is connected, and a second connection unit 12 to which a LAN cable connected to an external network is connected. The first connector 11 and the second connector 12 are preferably implemented as a connector that can connect a predetermined LAN cable, respectively. For example, the first connector 11 and the second connector 12 are preferably implemented to connect the RJ45 cable. In this case, the second connection part 12 connected to the external network is preferably implemented to be able to use a cable composed of an 8-pin (pins) connector and a cable composed of a 6-pin (pins) connector. More specifically, the currently commercially available LAN cable for an external network includes a LAN cable including an 8-pin connector or a LAN cable including a 6-pin connector, wherein the second connection part 12 connected to the external network is a 6-pin connector. It is preferable that the LAN cable including a LAN cable or an 8-pin connector is implemented to be connected. To this end, the second connector 12 may be implemented as an 8-pin connector, and the second connector 12 may perform the same function as the 6-pin connector by using a jumper. As such, when the second connection unit 12 is implemented, the network switching device does not need to be manufactured separately according to the type of the LAN cable, thereby increasing the utilization of the network switching device.

When a command for selecting a predetermined network is input through the input unit 40, the network selector 20 selects the network connection unit 10 corresponding to the selected network. More specifically, the network selector 20 is physically connected to the LAN card connection unit 90, which is equipped with a LAN card. When a user's computer (not shown) is connected to the internal network, for example, and a switch command to the external network is input through the input unit 40, the network selector 20 corresponds to the external network. The network connection unit 10, that is, the second connection unit 12 and the LAN card (not shown) connected to the LAN card connection unit 90 are connected. This allows the user's computer (not shown) to connect to the external network. If a user's computer is connected to an external network and a switch command to the internal network is input through the input unit 40, the network selector 20 may be a network connection unit 10 corresponding to the internal network. In addition, a LAN card (not shown) connected to the first connector 11 and the LAN card connector 90 is connected. This allows the user's computer to connect to the internal network. The network selector 20 may be implemented as an integrated circuit (IC) or a relay.

At this time, the operation display unit 30 is implemented by LEDs of different colors, so that the user can easily recognize the network currently operating. For example, the operation display unit 30 for the internal network is implemented with a red LED, and the operation display unit 30 for the external network is implemented with a green LED, when the user's computer is connected to the external network. When the user's computer is connected to the internal network, the red LED turns on to display the information about the network currently in operation.

The operation display unit 30 is preferably located where the installation space of the network switching device 100 can be secured. For example, the operation display unit 30 is preferably located below the network connection unit 10, that is, the connector of the first connection unit 11 and the connector of the second connection unit 12. However, the position of the operation display unit 30 is not limited thereto.

The storage medium connectors 80 and 800 are parts connected to a data cable for connecting a storage medium such as a hard disk drive (HDD), and may be configured as connectors. In this case, the storage medium connectors 80 and 800 may be one of various standard transmission methods, for example, Universal Serial Bus (USB), Serial Advanced Technology Attachment (SATA), Peripheral Component Interconnect (PCI), and Integrated Drive Electronics (IDE). It is preferable that the connector is configured to support the above standard transmission scheme. For example, when the storage medium connectors 80 and 800 are formed of the first storage medium connector 80 and the second storage medium connector 800, the first storage medium connector 80 is composed of an IDE connector. 2 The storage medium connection is preferably composed of S-ATA connector.

In this case, the first storage medium connection unit and the second storage medium connection unit may each include a plurality of connectors, and each connector may be connected to one or more physically separated storage media corresponding to an external network and an internal network. . That is, one storage medium may be connected to each connector through a single cable, or two storage media may be connected to each connector through a double cable.

In addition, when a plurality of connectors of the same type are provided, the color of each connector may be different so that a user may easily install the network switching device 100. For example, when the first storage medium connector 80 includes the first connector 81 and the second connector 82, the first connector 81 and the second connector 82 may be a red IDE connector and It is configured with a green IDE connector to connect the storage medium for the internal network to the first connector 81, and to the storage medium for the external network to the second connector 82. Likewise, the second storage medium connector 800 may have a different color of the connector. That is, when the second storage medium connector 800 includes the first connector 810 and the second connector 820, the first connector 810 and the second connector 820 may be connected to the red S-ATA connector and the second connector 820. By configuring the green S-ATA connector, it is possible to connect the storage medium for the internal network to the first connector 810, and to connect the storage medium for the external network to the second connector 820.

The first storage unit 600 may be physically connected to at least one of the first storage medium connector 80 and the second storage medium connector 800. Here, the first storage unit 600 may be used as a storage medium corresponding to an external network or an internal network.

However, some circuits of the network switching device 100 may be configured or may be configured in a removable form. 1 illustrates a state in which the first storage unit 600 is connected to the second connection unit 820 of the second storage medium connection unit 800.

As described above, if the storage medium connection unit 80 and 800 are implemented as connectors supporting different transmission methods, the user can configure a network switching system regardless of the transmission method of the storage medium. For example, as shown in FIG. 2A, a storage medium corresponding to an internal network and an external network is used as a storage medium of an IDE transmission method, or a network switching system using only a storage medium of an S-ATA transmission method as shown in FIG. 2B. Can be configured. Alternatively, as shown in FIG. 2C, a network switching system may be configured by using a storage medium of an IDE transmission method and a storage medium of an S-ATA transmission method.

The motherboard connection parts 95 and 950 are parts for connecting a storage medium connected to the storage medium connection parts 80 and 800 with a data cable through a main board (not shown) of the computer, and the storage medium connection parts 80 and 800. Implemented by the same type of connector, each connector corresponds to a plurality of storage medium connection (80, 800). For example, when the storage medium connectors 80 and 800 include a first storage medium connector 80 made of an IDE connector and a second storage medium connector 800 made of an S-ATA connector, the motherboard connector 95 , 950 preferably includes a first motherboard connector 95 consisting of an IDE connector and a second motherboard connector 950 consisting of an S-ATA connector. In addition, the connectors of the motherboard connectors 95 and 950 may be embodied in a color different from the connectors of the storage medium connectors 80 and 800, for example, black.

The storage medium selecting unit 70 is electrically connected to the storage medium connecting units 80 and 800 and the motherboard connecting units 95 and 950, and when a command for selecting a predetermined network is input through the input unit 40, the selected network is selected. The storage medium connection unit 80 and 800 connected to the storage medium corresponding to the storage medium and the motherboard connection units 95 and 950 corresponding thereto are selected. For example, when a command for selecting an external network is input while connected to an internal network, the storage medium selecting unit 70 may include a storage medium connection unit 80 and 800 and a storage medium to which a storage medium corresponding to the external network is connected. The motherboard connection portions 95 and 950 corresponding to the connection portions are selected.

For a more detailed description, the first storage medium connector 80 and the second storage medium connector 800 are each composed of an IDE connector and an S-ATA connector, and the first main board connector 95 and the second main board. An example in which the connection part 950 corresponds to the first storage medium connection part 80 and the second storage medium connection part 800 will be described as an example. At this time, when the storage medium for the external network is connected to the second storage medium connection unit 800, if a command for selecting an external network is input through the input unit 40, the storage medium selection unit 70 is a second The storage medium connector 800 and the second motherboard connector 950 are selected. As a result, data is stored between the mainboard and the storage medium for the external network connected to the second storage medium connector 800 through the second storage medium connector 800, the storage medium selector 70, and the second motherboard connector 950. To be exchanged. The storage medium selector 70 may be implemented as an integrated circuit (IC) or a relay of a bus switch method, but is not limited thereto.

The transmission method converting unit 710 is electrically connected to the storage medium connecting units 80 and 800, and converts a specific transmission method into another transmission method. For example, the transmission method converter 710 converts the S-ATA transmission method to the IDE transmission method or converts the IDE transmission method to the S-ATA transmission method.

Although not shown, the transmission method converting unit 710 includes a connector corresponding to a specific transmission method, a controller integrated circuit (IC), and a peripheral circuit that controls the transmission method. The transmission method converting unit 710 may be implemented by a circuit or a removable type in the network switching device 100, a type of transmission method (for example, IDE, SATA, USB, IEEE1394, etc.), the storage medium connection unit 80 However, there is no restriction on the type or number of storage media connected.

As such, when the transmission method converter 710 is used, storage media of different transmission methods may be connected and used as one. For example, as illustrated in FIG. 2D, the transmission method conversion unit 710 is connected to the second connection unit 820 of the second storage medium connection unit 800, and the IDE transmission method is S-ATA transmission method. In case of conversion, the first storage unit 810 of the second storage medium connector 800 connects an S-ATA storage medium, and the transmission method conversion unit 710 includes a first storage unit that supports an IDE transmission method ( 600) can be connected. Thus, the storage medium of the S-ATA transmission method and the first storage unit 600 of the IDE transmission method may be connected to the second storage medium connection unit 800.

As another example, as shown in FIG. 2E, the transmission method conversion unit 720 is connected to the second connection unit 82 of the first storage medium connection unit 80, and the S-ATA transmission method is an IDE transmission method. In case of conversion, the first storage unit 81 of the first storage medium connector 80 connects an IDE type storage medium, and the transmission method conversion unit 720 supports a first storage unit (S-ATA). 600) can be connected. Thus, the storage medium of the IDE transmission method and the first storage unit 600 of the S-ATA transmission method may be connected to the first storage medium connection unit 800. However, the use example is not limited thereto and may be applied in various ways. It is possible.

Meanwhile, the second storage unit 60 temporarily stores data to be moved when data is moved between storage media corresponding to each network. For example, when the data of the storage medium for the internal network is to be moved to the storage medium for the external network, the user stores the data to be moved in the second storage unit 60, switches the computer to the external network, and then By accessing the storage unit 60, data of the second storage unit 60 may be moved to a storage medium for an external network. The second storage unit 60 may operate by the controller 50 or may operate independently of the controller 50.

In addition, when data of the second storage unit 60 is transmitted to a predetermined storage medium, it may be controlled by a unidirectional transmission method or a bidirectional transmission method.

In this case, bidirectional means that the data of the second storage unit 60 can be accessed in the internal and external networks, respectively. For example, when the computer is used as the internal network, the user may store data of the storage medium for the internal network in the second storage unit 60 or delete or modify data of the second storage unit 60. Further, even when the computer is switched to the external network, data of the second storage unit 60 may be modified and deleted, and data of the storage medium for the external network may be stored in the second storage unit 60. That is, the bidirectional means that both the reading and the writing of the data of the second storage unit 60 can be performed in the internal and external network environments.

On the other hand, when a switch to a predetermined network is performed, the unidirectional means that the access range of data of the second storage unit 60 in the switched network is limited. For example, when the computer is connected to the internal network, the user may store data of the storage medium for the internal network in the second storage unit 60 or modify or delete data in the second storage unit 60. That is, both reading and writing of data in the second storage unit 60 can be performed. After the computer is switched to the external network, only reading of the data in the second storage unit 60 is possible. That is, the data of the storage medium for the external network may not be recorded in the second storage unit 60 or the data of the second storage unit 60 may be modified or deleted. Even when a switch is made from the external network to the internal network, the access range for the second storage unit 60 may be limited as described above. The access range for the second storage unit 60 may be selectively set by the user.

The second storage unit 60 may be formed in various forms by those skilled in the art. For example, it may be implemented in some circuit in the network switching device 100 or in a form detachable from the network switching device 100. The second storage unit 60 may be implemented as a nonvolatile memory device such as a ROM, a PROM, an EPROM, an EEPROM, a flash memory, or a volatile memory device such as a RAM, or a storage medium such as a CD or a hard disk drive. It is not limited.

On the other hand, the controller 50 controls the overall operation of the network switching device 100 according to a user's command. For example, when a network switch command is input, a control signal is generated and transmitted to the network selector 20 so that the user can switch to the network selected by the user. The control signal is generated and transmitted to the storage medium selection unit 70 so that the storage medium corresponding to the switched network can be selected.

As another example, when the network is switched, it is determined whether there is an external storage medium, and the network is switched according to the determination result. That is, if an external storage medium exists at the time of network switching, the network switching is stopped to prevent virus infection by the external storage medium. Determination of the presence or absence of an external storage medium is selectively made according to preset contents, and the setting contents can be changed by the user. In addition, the controller 50 controls power supply and data transmission to the storage medium. The controller 50 may be implemented as, for example, a micro controller.

Components as described above may be provided on a single printed circuit board (PCB). One side of the printed circuit board is provided with a connection terminal (not shown) is mounted in the expansion slot, for example, a PCI slot provided in the motherboard.

Next, an operation process of the network switching device 100 according to the embodiment of the present invention will be described with reference to FIG. 3.

For convenience of description, the network switching device 100 according to the embodiment of the present invention includes a first storage medium connection unit 80 of an IDE transmission method and a second storage medium connection unit 800 of an S-ATA transmission method. The first storage medium connection unit 80 and the second storage medium connection unit 800 each include a first connection unit and a second connection unit, and the second connection unit 820 of the second storage medium connection unit 800 includes a first storage unit ( An example in which 600 is physically connected will be described as an example. In addition, the first and second connectors 81 and 82 of the first storage medium connector 80 and the first and second connectors 810 and 820 of the second storage medium connector 800 are respectively internal and external. It is assumed that a storage medium corresponding to the network can be connected.

First, the user mounts a connection terminal (not shown) in the expansion slot of the motherboard, and then connects the internal network cable and the external network cable to the network connection unit 10, respectively. For example, an internal network cable is connected to the first connection part 11 and an external network cable is connected to the second connection part 12.

Then, the user checks the transmission method and purpose of the existing storage medium connected to the computer, and connects to the storage medium connection unit 80 and 800. For example, when using an existing storage medium that supports the IDE transmission method as a storage medium for an internal network, a user may connect a data cable connected to the existing storage medium to the first connection portion 81 of the first storage medium connection portion 80. Connect. Here, since the first connecting portion 81 and the second connecting portion 82 of the first storage medium connecting portion 80 are implemented with connectors of different colors, the user can easily distinguish the connector to connect the existing storage medium. .

After the printed circuit board is mounted in the expansion slot of the motherboard, when the computer is powered on, the system is checked through the Basic Input Output System (BIOS), and the check result is displayed on the monitor (not shown). Is displayed through. At this time, the + 5V power is supplied to the network switching device 100 so that the network switching device 100 operates (S310).

Thereafter, the controller 50 selects a boot loader to boot into an internal network or an external network. When the boot loader is selected, the boot loader may be selected according to a preset value or a user's command (S320).

More specifically, when a predetermined network is selected within a predetermined time while a screen for selecting an internal network or an external network is displayed (S320, Yes), the controller 50 may boot to the network selected by the user. The network selector 20 and the storage medium selector 70 are controlled (S330). For example, when the internal network is selected by the user within a predetermined time, for example, 5 seconds after the network selection screen is output, the controller 50 may select the network selector 20 and the storage medium selector 70. To control the booting to the internal network.

At this time, the controller 50 transmits a + 5V high level signal to the storage medium for the internal network and a low level signal of 2V or less to the storage medium for the external network. The storage medium for the internal network receiving the high level signal transmits operating information of the hard disk to the BIOS.

If a user command is not input within a predetermined time (S320, NO), the controller 50 controls the network selector 20 and the storage medium selector 70 to set a default network, for example, Allow booting into an external network (S325).

When booting to a predetermined network, for example, an external network is completed, the storage medium for the internal network and the storage medium for the external network operate independently of each other. That is, when using an external network, the storage medium for the internal network cannot be accessed. Likewise, when using the internal network, the storage medium for the external network cannot be accessed.

Thereafter, the controller 50 periodically checks the operating state of the network and controls the data flow between the storage medium and the second storage unit 60 (S340). If data need to be moved between storage media that are independent of each other, the data may be moved using the second storage unit 60. For example, when the data of the storage medium for the external network is to be moved to the storage medium for the internal network, the user stores the data to be moved in the second storage unit 60 and then performs network switching.

When a network switch command is input through the input unit 40, the controller 50 checks whether an external storage medium such as a floppy disk, a USB memory, an optical storage medium, or the like is inserted (S360). The network switch is executed according to the result of the check.

For example, when switching from an external network to an internal network, as a result of checking whether an external storage medium is inserted, if an external storage medium is inserted (S360, Yes), the network switching process is stopped (S365), and the external storage medium. Prevents viral infections caused by

As a result of checking whether the external storage medium is inserted, if there is no external storage medium (S360, NO), the resource of the currently operating storage medium is terminated (S370). For example, when a network switch command is executed while connected to an external network, the controller 50 terminates the resources of the storage medium for the external network.

After that, the controller 50 controls the network selector 20 so that the computer can be connected to the internal network (S380). That is, the internal network may be selected by controlling the network selector 20 to transmit a high level signal to the first connector 11. The storage medium selector 70 is controlled to allow the storage medium corresponding to the internal network to be driven. That is, by controlling the storage medium selection unit 70 transmits a high level signal to the first connection unit 81 of the first storage medium connection unit, the storage medium for the internal network can be driven.

When switched to the internal network, the second storage unit 60 may be accessed to move the data to a storage medium for the internal network. At this time, the data flow between the internal network storage medium and the second storage unit 60 is controlled by the controller 50 according to a preset transmission scheme. The data of the second storage unit 60 may be transmitted in a unidirectional transmission method or a bidirectional transmission method, and the transmission method may be selectively set by a user.

When set to the one-way transmission method, the access right to the second storage unit 60 in a predetermined network is restricted. For example, the write right to the second storage unit 60 in the internal network may be limited, and the access right to the second storage unit 60 in the external network may not be limited. That is, in the external network, the data of the second storage unit 60 may be read and written, and in the internal network, only the data of the second storage unit 60 may be read.

As another example, the right to write to the second storage unit 60 in the external network may be limited, and the right to access to the second storage unit 60 in the internal network may not be limited. That is, in the state where the switch to the internal network is made, the data of the second storage unit 60 can be read and written, and in the external network, only the data of the second storage unit 60 can be read, 2 may not be able to modify or delete the data in the storage (60).

If the bidirectional transmission scheme is set, the access right to the second storage unit 60 in the predetermined network is not limited. That is, both the external and internal networks may be configured to enable both reading and writing of data in the second storage unit 60.

Although the network switching apparatus according to the present invention has been described with reference to the drawings exemplified as above, the present invention is not limited to the embodiments and drawings disclosed in the present specification, and is intended by those skilled in the art within the technical scope of the present invention. Of course, various modifications may be made.

As described above, the network switching device according to the present invention has one or more of the following effects.

First, since a storage medium of various transmission methods or a conversion method of a transmission method can be used, the utilization of the existing storage medium can be increased, and data transfer can be easily performed.

Second, by adding a storage medium in the network switching device, the user can eliminate the need to purchase a separate storage medium, there is an advantage that can be installed in a small computer.
