The progress information is basically stored in the data storage unit 190, but may also be stored in the OPS module 180, which will be described later.

The communication unit 160 serves to transmit and receive data with external devices through a wired or wireless network.

The communication unit 160 may be configured to include a communication module that enables communication such as Bluetooth, Wi-Fi, 3G, 4G, and 5G.

The control unit 170 serves to control the overall operation of the electronic whiteboard 100. When the teacher is authenticated through the RFID reader 120 or the fingerprint recognition module 130, the control unit 170 turns on or off the touch display panel 114 and stores or retrieves page information of the digital textbook.

For example, when the RFID reader 120 receives information from the RFID tag 200 when the touch display panel 114 is off, the control unit 170 activates or turns on the OPS module 180 and turns on the touch display. The panel 114 is turned on, the last saved page of the digital textbook corresponding to the teacher and subject is called from the OPS module 180 and displayed on the touch display panel 114, and the touch display panel 114 is turned on. When the RFID reader 120 receives information from the RFID tag 200, the current page information of the digital textbook can be saved and the touch display panel 114 can be turned off.

In the above example, the case where the teacher touches the RFID tag 200 with the RFID reader 120 has been described as an example, but when the teacher touches the fingerprint recognition module 130 with his or her finger, it operates in the same manner as above. can do.

As described above, when the touch display panel 114 is turned on or off, the control unit 170 stores the class start date and class end date and time information along with the page information of the digital textbook at that time in the data storage unit 190. You can do it.

Referring to FIG. 4, the control unit 170 includes a user authentication unit 171, an on-off control unit 172, and a progress output unit 173.

The user authentication unit 171 serves to authenticate the user based on preset authentication information.

Authentication can also be performed based on

In addition, the user authentication unit 171 is also capable of authenticating the user through user face recognition and voice recognition based on the data analyzed by the AI data analysis unit 140.

Since the on-off control unit 172 performs the on-off control operation of the touch display panel 114 of the control unit 170 described above, detailed description is omitted.

The progress output unit 173 serves to transmit teacher, subject, class date and time, and progress information of the digital textbook through the communication unit 160 to an external device for which the user has been authenticated through the user authentication unit 171.

The progress output unit 173 can transmit the above information to the teacher terminal 300 and the server 400. Details will be described later with reference to FIG. 7.

The data storage unit 190 serves to store personal information, subject information, digital textbook information and progress information, class history information, captured video data, and recorded voice data for each teacher.

Digital teaching material information is stored and managed in the OPS module 180 as described above, but additionally, information stored in the data storage unit 190, such as personal information of the teacher who conducts classes using each digital teaching material information and progress information of the teacher, is stored and managed in the OPS module 180. All or part of may be additionally stored and managed.

Figure 5 is a flowchart explaining the process of building a database of an electronic whiteboard according to an embodiment of the present invention.

Referring to Figure 5, the teacher can register his or her personal information (S510). At this time, personal information can be registered by the teacher directly entering the electronic whiteboard 100 while touching the touch display panel 114 of the electronic whiteboard 100, or by linking the electronic whiteboard 100 with the server 400 connected to the network. It is also possible to input through a website or application.

When entering through a website or application, the teacher can use his or her smartphone or PC to access the website or run the application and enter personal information while signing up and entering information such as personal information and subject information. .

Additionally, the teacher can register the RFID tag and fingerprint information on the electronic whiteboard 100 (S520).

That is, after step S510, the teacher registers RFID tag information by contacting the RFID tag 20 with the RFID reader 120, or registers a fingerprint by contacting the fingerprint recognition module 130 with his or her thumb or index finger. You can.

Additionally, the teacher may register digital teaching material information on the electronic whiteboard 100 after step S510 (S530). Digital teaching material information can also be stored directly in the data storage unit 190, which is the internal storage of the electronic whiteboard 100, and in the storage of the server 400 connected to the electronic whiteboard 100 through a network. .

In FIG. 5 , the order of steps S520 and S530 may be changed.

The database constructed in FIG. 5 is basically stored in the data storage unit 190, but all or part of it may also be stored in the OPS module 180.

In one embodiment, information on digital teaching materials is stored in the OPS module 180, and subject information for each teacher, type information of digital teaching materials, RFID tag information, and progress information are stored in the data storage unit 19 to provide RFID tag information. When received, information matching this may be extracted from the data storage unit 190 and based on this, the corresponding digital teaching material may be retrieved from the OPS module 180 based on the teacher and progress information.

However, the above embodiment is only an example, and it may be possible for digital textbook information and progress information for each teacher to be matched and stored in the OPS module 180.

Figure 6 is a flowchart illustrating a method for controlling the on and off of an electronic whiteboard according to an embodiment of the present invention.

Referring to Figure 6, the electronic whiteboard 100 of the present invention receives the teacher's RFID tag information or fingerprint information using the RFID reader 120 or the fingerprint recognition module 130 (S610).

Next, the control unit 170 determines whether the touch display panel 114 of the electronic whiteboard 100 is currently powered on (S620).

As described later, when a class begins, the electronic whiteboard 100 turns on the touch display panel 114 to output digital textbooks, and when the class ends, the touch display panel 114 turns off and enters a mode to minimize power consumption. .

Of course, the power to the entire electronic whiteboard 100 is not completely cut off, and the touch display panel 114 is blocked, but the RFID reader 120 and the fingerprint recognition module 130 enter the power minimization mode to be operable. it means.

If it is determined in step S620 that the touch display panel 114 is not in the on state, that is, in the off state, the control unit 170 activates or turns on the OPS module 180 (S630) and turns the touch display panel 114 on. Turn on the power to (114) (S632).

At this time, activating the OPS module 180 means converting the OPS module 180 from the standby mode to a general active mode when the OPS module 180 is in a standby mode, which is a mode that minimizes power consumption. Turning on means supplying power and booting the OPS module 180 when the power is off.

Next, the control unit 170 retrieves the digital textbook storage copy corresponding to the teacher certified in step S610 and the teacher's subject information from the OPS module 180 and outputs it to the touch display panel 114 (S640).

At this time, the control unit 170 stores the time when the digital textbook is output, that is, the class start date and time, and the output page information in the data storage unit 190 (S642)

The teacher then conducts a class using the electronic whiteboard 100, and the class history information generator 143 begins to generate class history information in real time based on the sound information recorded from the microphone module 117 ( S644).

When the teacher ends the class, user authentication is performed by bringing the RFID tag 200 close to the RFID reader 120 or touching the fingerprint recognition module 130 with a finger. In this case, steps S610 and S620 are performed again. do.

In this case, since it is determined that the touch display panel 114 is in the on state in step S620, step S650 is entered and the control unit 170 stores the class end date and page information of the digital textbook at that point in the data storage unit 190. do.

Additionally, the control unit 170 stores the class history information generated from the start of the class to the end of the class in the data storage unit 190 in conjunction with the class time information and page information (S652).

Next, the control unit 170 turns off the power of the touch display panel 114 to minimize power consumption (S654).

At this time, the control unit 170 determines whether the first reference time has elapsed since turning off the touch display panel (S660).

If it is determined that the first reference time has elapsed in step S660, the control unit 170 switches the OPS module 180 to standby mode (S670).

Additionally, the control unit 180 determines whether the second reference time has elapsed since turning off the touch display panel (S680).

If it is determined that the second reference time has elapsed in step S680, the control unit 170 turns off the power of the OPS module 180 (S690).

The second reference time is set to be greater than the first reference time.

For example, if the first reference time is 15 minutes and the second reference time is 30 minutes, the OPS module 180 switches to standby mode when 10 minutes elapse without RFID tag information being received after turning off the display panel 114. power consumption can be reduced, and after 30 minutes, the OPS module 180 is turned off to minimize power consumption.

In other words, since the break time at school is usually 10 minutes, there may be a case where the next teacher tags with an RFID tag around 10 minutes. In this case, the OPS module 180 quickly switches from standby mode to active mode to quickly activate digital Information about the textbook can be output on the display panel 114.

Meanwhile, when RFID tag information is received when the OPS module 180 is turned off after 30 minutes, power must be supplied to the OPS module 180 to boot, so the digital textbook is displayed on the display panel 114. There may be a slight delay when the information is output.

The first standard time and the second standard time can be set differently depending on the situation, such as the place where the electronic whiteboard 110 is installed, the subject, etc., and the first standard time and the second standard time are fixed values for each timeline. It is also possible to set it to a variable value.

By operating as described above, power consumption can be minimized and digital textbook information can be output together with the on operation of the display panel 114 or stored together with the off operation by linking with progress information only through simple user authentication operations such as RFID tagging.

The conditions of the first reference time and the second reference time above are only an example, and the two conditions, that is, the first condition and the second condition, can of course be set using information other than time.

In addition, in FIG. 6, the control unit 170 is shown to perform a set operation depending on whether the display panel 114 is on or off when user authentication information is received through an operation such as RFID tagging. In addition to the user authentication information, it is also possible to configure the user's location information to be additionally performed.

The teacher can use the teacher terminal 300 as shown in Figure 7. If the teacher terminal 300 is a smartphone, the electronic whiteboard 100 can receive GPS signal information of the smartphone through the communication unit 160. there is.

In this case, even if user authentication information such as RFID tag information is received, the control unit 170 only receives the user's location information linked to the user authentication information, that is, if it is within a preset reference location range based on the GPS information of the linked user's terminal. It can be configured to perform the next step of operation.

For example, since the teacher moves with a smartphone, the electronic whiteboard is used based on user authentication information such as RFID tag information only when it is determined that the teacher is located within a certain radius of the classroom where the class will be conducted based on the smartphone's GPS information. The display panel 114 of 100 can also be configured to be controlled on and off.

If configured in this way, it can have the effect of preventing abnormal situations such as someone other than the teacher arbitrarily conducting a class using only an ID card with an embedded RFID tag.

At this time, determination of location information may be performed by additionally using Bluetooth or Wi-Fi signal information in addition to GPS signal information, and in this case, more detailed location determination may be possible.

Figure 7 is a network connection diagram for explaining how the electronic whiteboard transmits progress information to an external device according to an embodiment of the present invention.

As shown in Figure 7, the server 400 can be connected to N electronic whiteboards (101, 102 ~ 10N) and teacher terminals (301, 302 ~ 30N) through a network.

Each electronic whiteboard 161 can transmit class progress information for each teacher conducting a class using itself to the server 400, and the teacher terminal 310 can be connected to the website or website provided by the server 400. Through the application, you can receive and check information that you can view with your permission.

At this time, the teacher terminal 300 may be a desktop computer, laptop, tablet, smartphone, etc. used by the teacher.

Although FIG. 7 shows the teacher terminal 300 checking class progress information through the server 400, it is also possible for the teacher terminal 300 to check by directly connecting to the electronic whiteboard 100 through the communication unit 160. do.
