Typically, a large-sized monitor (for example, a 70-inch monitor) or a screen is used as the copyboard, and a user can directly write on the monitor. Therefore, when the presentation is performed in the lecture or meeting using the electronic board, the user stays on one side (e.g., left and right sides) of the electronic board in parallel with the board and explanation in accordance with the convenience of explanation.

For example, the user stands on one side (e.g., left side or right side) of the copyboard for the purpose of not covering the contents displayed on the copyboard during presentation, or generally stands close to the content to be described. And alternately moves on both sides of the line. At this time, when the user needs to emphasize specific contents or to explain in detail in the presentation, the user changes the color or thickness of the pen, displays an image or document file to be referred to, or deletes the already written content.

Therefore, it is desirable that the copyboard be interfaced so that the user can quickly select a desired menu (e.g., pen selection, thickness selection, sheet selection, file loading, printing, etc.)

However, although the conventional electronic blackboard includes various functions and menus for use, it is possible to use only the functions of the electronic blackboard and the number of menus without considering the movement of the user, There is an inconvenience that it is necessary to move to a position (or a position for calling a menu) to operate the menu, and then to move to a previous position to continue the explanation again, and intuitively judge functions and menus included in the electronic blackboard There is a problem that the convenience of the user is deteriorated by selecting an inappropriate menu.

In addition, the conventional electronic blackboard displays a plurality of execution icons (execution icons corresponding to a plurality of programs installed in the computer) provided by a computer operating system (e.g., Microsoft's Windows, Apple's MacOS, etc.) A user has to search for and select an execution icon for driving the electronic blackboard among the icons. That is, there is a troublesome problem that a boot screen is first displayed by booting in a window mode (a startup screen mode provided by a computer operating system), and then a desired icon (an execution icon for driving the electronic blackboard) among the execution icons is selected and selected .

Also, an electronic board, which usually includes a large-sized monitor and a main body (for example, a computing main board or a computer), is provided with an independent power supply unit separately.

Therefore, in order to use the electronic board in the related art, the power switch of the large-size monitor must first be turned on and turned on by turning on the power switch of the main body. In order to terminate the use of the electronic board in the related art, first, the system shutdown procedure was performed in the window mode so that the main body was turned off and the power switch of the large monitor was turned off. Thus, conventionally, a considerable time is required for starting and ending the use of the electronic whiteboard, and there is a problem that power on / off is cumbersome.

FIG. 13 is a diagram illustrating a schematic configuration of a power supply device of a smart board according to an embodiment of the present invention.

13, the power supply unit 150 of the smart board 100 according to an exemplary embodiment of the present invention includes a power control unit 151 and a power switching unit 152. [

The power control unit 151 senses an input of the power on / off selection unit 111 (that is, an input of a power switch) and controls the display unit 130 of the smart board 100 (I.e., an AC power source) to the monitor. Accordingly, the display unit 130 (i.e., the monitor) is switched on by the applied power (i.e., AC power). At this time, the power control unit 151 may be replaced by the controller 120 or may be included as an additional configuration unit.

The power switching unit 152 controls the display unit 130 and the computing main board built in the smart board 100 according to the control of the power control unit 151. [ (I.e., an AC power source) to at least one of the plurality of power sources 123.

For example, the power switching unit 152 may include a relay.

The power control unit 151 controls the application time of the power (i.e., AC power) applied to the display unit 130 (i.e., the monitor) or the computing main board ) And the application order (or blocking order).

For example, the power control unit 151 first applies power to (or disconnects) the display unit 130 (i.e., the monitor) according to whether the smart board 100 is driven / terminated, (Or the computer main body) 123 may be first powered on (or off), and then the display unit 130 may be powered on (or shut off) (That is, the monitor).

The power control unit 151 outputs a control signal for the safe termination of the system of the computing main board 123 (i.e., the computer main body) 123 (i.e., the system including the input / output devices connected to the computer main body) Status can be monitored.

For example, the power control unit 151 can boot the system by outputting a system start signal (or a system on signal) after powering the computing main board 123 (i.e., the computer main body) Also, assuming that the system is in operation, the power control unit 151 outputs a system shutdown signal (or a system off signal) to shut down the system (i.e., shut down the system in windowed mode) , The computer main body) 123 can be cut off. In other words, when it is assumed that the computing main board 123 (i.e., the computer main body) is a control board (i.e., a second control board) The control unit 122 may perform a boot / shutdown operation of the system.

FIG. 14 is a flowchart for explaining a method of controlling the power of the smart board in FIG.

As shown in FIG. 14, the power control unit 151 senses input of a power on switch (S401).

Here, the power on switch (not shown) means that the power on / off selection unit 111 inputted when the current state of the smart board 100 is in the power off state acts as a power on switch.

Accordingly, the power controller 151 controls the power switching unit 152 to apply power (AC power) to the display unit 130 (i.e., the monitor) (S402).

The power control unit 151 controls the power switching unit 152 to apply power to the computing main board 123 (S403). In addition, the power control unit 151 outputs a system start signal (or a system on signal) to the computing main board 123 (i.e., the computer main body) 123 to boot the system.

When the system of the computing main board 123 (that is, the computer main body) 123 is booted as described above, the smart board 100 can be used as an electronic board by executing a writing program.

When the user inputs the power on / off selection unit 111 to terminate the use of the smart board 100, the power control unit 151 senses input of a power off switch (not shown) S404).

Here, the power on / off selection unit 111 may perform a role of a power off switch (i.e., a role of a toggle switch) according to the current state of the smart board 100 (power on / off state).

When the input of the power off switch (not shown) is sensed, the power control unit 151 transmits a system shutdown signal (or a system off signal) to the computing main board 123 (S405).

Then, the power control unit 151 detects that the system of the computing main board (i.e., the computer main body) 123 is terminated (S406).

When the end of the system is detected, the power control unit 151 cuts off the power (AC power) applied to the computing main board 123 (S407).

Then, the power control unit 151 cuts off the power (AC power) applied to the display unit 130 (i.e., the monitor) (S408).

As described above, the embodiment of the present invention has the effect of improving the convenience of the user by quickly and stably switching on or off the power supplied to the monitor and the main body included in the smart board to a single switch input.

On the other hand, in the above embodiment, the application of the AC power (that is, the AC power) has been described. However, the DC power supply (that is, the DC power supply) may be directly applied depending on the configuration of the power supply.

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 embodiments, but, on the contrary, I will understand the point.
