Hereinafter, the operation of the copyboard capable of multiple connection through screen division according to an embodiment of the present invention having the above-described configuration will be described.

4 is a flowchart illustrating an overall operation of the electronic whiteboard capable of multi-access through screen division according to an embodiment of the present invention.

Referring to FIGS. 1 to 4, a copying board capable of multi-accessing through screen division according to an embodiment of the present invention activates a function of a touch screen included in the display unit 11 when powered on (S11) (S12). Here, the power of the copyboard is turned on, which means that the power of the display unit 11, the multipurpose gateway apparatus 13, and the transmitter unit 15 included in the copyboard are all turned on.

Then, the application for the copyboard installed in the multi-purpose gateway device 13 is executed (S14), the formatter function provided by the application for the copyboard is activated through execution of the application, and the external user terminal is ready to be connected (S15). On the other hand, in another embodiment of the present invention, even when a separate application for the electronic whiteboard is not executed, the signer function may be always activated when the power of the display unit 11 and the multi-purpose gateway device 13 is turned on.

5, when a touch for screening is performed by the touch screen device included in the display unit 11, the touch control module 134 receives information about a position where the touch is performed by the touch control module 134, It is noted that the panel-related operation for controlling the image processing module 133 to output the screen data in which the panel is made according to the received information to the display unit 11 in the image processing module 133 is omitted.

Next, when an attempt to connect the user terminals 21 and 22 occurs (S15), the multi-purpose gateway device 13 can determine whether to permit the connection of the user terminals 21 and 22. [

For example, in the case of the user terminal 21 capable of directly communicating with the wireless communication module 131 in step S15, an input for requesting access by the user using the application for the electronic whiteboard, which is pre-installed in the user terminal 21 Can be input to the user terminal 21. To this end, the user terminal 21 must be in a standby state in a state capable of communicating with the wireless communication module 131 included in the multipurpose gateway device 13. [ For example, when the wireless communication module 131 of the multi-purpose gateway device 13 is implemented as an access point of a wireless LAN, the user terminal 21 may be a wireless LAN access point To form a connection with the wireless communication module 131 in advance.

As another example, in the case of the user terminal 22 that is not capable of direct communication with the wireless communication module 131 in step S15, the user terminal 22 via the transmitter unit 15 can make a connection with the multipurpose gateway device 13 Can be requested. When the electronic blackboard is powered on (S11), the wireless communication module 131 and the transmitter unit 15 of the multi-purpose gateway device 13 can be sta- ble in a connectable state through mutual communication. When the wireless communication module 131 operates as an access point of the wireless LAN, the transmitter unit 15 transmits the wireless communication module 131 to the wireless communication module 131, which is the access point, using previously set information (for example, SSID, password, Connection can be formed. The transmitter control unit 150 controls the wireless communication unit 151 to transmit the connection request message to the wireless communication module 131. The wireless communication unit 151 transmits the connection request message to the wireless communication module 131, Can be controlled.

In the process of determining whether connection is allowed or not (S16), the administrator who manages the copyboard can determine whether or not the connection is allowed by using the remote controller unit 17. In the default state, it is possible to freely allow the connection to the copyboard through the user terminal. However, if there are too many connections or if it is necessary to make a selective connection, Inputs can be provided to the electronic board. For example, a lecturer may be an administrator who manages the electronic blackboard, and a user who attempts to access the multi-purpose gateway device 13 using his / her user terminal . When the lecturer transmits a connection request by operating his or her own user terminal or transmitter unit 15 so that the contents displayed on his or her own user terminal are displayed on the display unit 11, It is possible to operate the remote controller unit 17 by determining whether or not to allow the student to access the user terminal. The lecturer decides whether or not to permit / deny by operating the key input unit 171 provided in the remote controller unit 17 by inputting the connection allow / deny key, and outputs a signal corresponding to the input generated in the key input unit 17 The signal control unit 170 controls the signal transmission unit 173 to transmit the signal to the remote control transmission / reception module 137. [

In the above-described example, the administrator has provided an input for determining whether or not to permit the connection using the remote controller unit 17. However, in the case where the menu for determining the connection permission is displayed on the display unit 11, The user may touch the menu on the touch panel 11 to determine whether the connection is allowed or not.

As another example of the process S16 of determining whether or not the connection is permitted, the central control module 130 may determine whether or not to directly allow connection without receiving user input. In this example, the setting can be made according to the setting pre-inputted by the manager through the electronic board application installed in the multi-purpose gateway device 13. [ For example, when the setting for not allowing connection of an external user terminal is made, or when the connection limit of the user terminal is set, the central control module 130 can block the connection of the user terminal.

When the user terminal is allowed to be connected, the central control module 130 of the multi-purpose gateway device 13 checks the number of the divided area currently generated in the display unit 11 (S18) And controls the image processing module 133 to display a screen in which the divided areas are rearranged according to the number of divided areas, thereby displaying a plurality of divided areas on the display unit 11. [ Thereafter, the central control module 130 may control the image processing module so that a screen or contents inputted from the connected user terminal can be displayed in a divided area set to display the corresponding user terminal.

If the user connection is denied, the central control module 130 generates a connection disable message and controls the wireless communication module 131 to transmit the connection disable message to the user terminal (S17)

Meanwhile, an embodiment of the present invention can provide an electronic whiteboard management system for managing a plurality of electronic whiteboards.
