It comprises a power icon 15 for the purpose.

About 65,000 English sentences or Korean sentences are printed on the textbook 110, and the number may be extended by 65,000x192 when the content is selected after selecting the textbook, and an index is assigned to each sentence. . Such a control icon may be printed on each page of the textbook 110 of the textbook 110 or may be selectively printed on one of odd or even pages.

Although not shown in the figure, a Zigbee communication module, Bluetooth (Bluetooth) for wireless communication between the communication module 171 of the lecturer terminal 120 and the communication module 191 of the student terminal 130 tooth) If a wireless communication module such as a communication module is used, the wireless communication between the lecturer terminal 120 and the plurality of learner terminals 130 may be wirelessly performed.

Referring to the operation of the learning system using the network according to the present invention configured as described above are as follows.

First, the lecturer terminal 120 and the learner terminal 130 recognizes the index 111 printed on the textbook 110 through the sensors 151 and 181 of the input unit, respectively, and corresponding audio signals. And video signals are read from the memories 162 and 202 and output and displayed through the speakers / headphones and the display units 166 and 206.

That is, the index 111 printed on the textbook 110 is recognized through the sensors 151 and 181 of the input unit, and is converted into a digital signal by the converters 152 and 182 and output. The CPU 161 and 201 analyze the converted digital data and read and output the audio and video signals corresponding to the index 111 from the memories 162 and 202. The audio output unit 163 or 203 then outputs the audio signal through a speaker / headphone or through the wireless transmitters 165 and 205. In addition, the display units 166 and 206 display the video signal on the LCD.

The lecturer terminal 120 reads the control icon (FIG. 6) and outputs data corresponding to a voice signal and an index for all the students' terminals, groups, or individuals.

This will be described in detail as follows.

7 is a flowchart illustrating the operation of the lecturer terminal according to the present invention.

First, IDs for selecting individual, all, and groups of each student terminal 130 are given. That is, each student terminal 130 is assigned an individual ID (for example, 01H to F0H), and an ID (for example, FFH) and a first group for selecting the entire student terminal 130 are assigned. ID for selecting (eg FAH), ID for selecting the second group (eg FBH), ID for selecting the third group (eg FCH), selecting the fourth group ID for example (e.g., FDH) and ID for selecting the fifth group (e.g., FEH).

Therefore, a case of selectively outputting a voice signal and an index signal or controlling each learner terminal through the control icon will be described.

First, a control icon for selecting a student terminal is recognized (1S). In other words. Through the sensor 151 of the lecturer terminal 120, one of the entire icons 13, one of the first to fifth group icons 16-20, or individual icons 21-31 of the control icons shown in FIG. Choose one.

As such, when one of the icons is recognized by the sensor 151, the CPU 161 assigns an ID to the selected icon (2S, 3S, 4S). That is, when the entire icon 13 is selected, a corresponding ID (FFH) is given (2S), and when a group is selected, a corresponding ID (one of FAH, FBH, FCH, FDH, FEH) is given (3S). ), And also gives an individual ID (one of 01H-F0H) (4S).

Then, the MIC icon 11 or the content icon 12 is selected according to whether to transmit a voice signal or a content (index) to the selected student terminal 130 (5S).

If the MIC icon 11 is selected, the CPU 161 transmits a voice signal output from the microphone 153 of the lecturer terminal 120 to an audio line of the communication line (FIG. 5). Control and transmit the voice signal input to the microphone (153).

If the content icon 12 is selected, the CPU 161 activates the communication module 171 (7S), and then transmits content data corresponding to the index input through the sensor 151 ( 8S).

In addition, although not shown in the drawing, in order to reset the respective student terminal 130 by selecting the icon as described above, to select and transmit the individual learning icon 14, or to turn on the power of each student terminal 130 If you want to turn off, select the power icon (15) to transmit.

Meanwhile, the student terminal 130 selectively receives and outputs or displays a voice signal or content data transmitted from the lecturer terminal 120.

This will be described in detail as follows.

8 is an operation flowchart of the student terminal according to the present invention.

The central processing unit 201 of the student terminal 130 recognizes the ID included in the head data of the communication format input through the communication line to determine whether the recognized ID corresponds to the own terminal ( 11S).

If the ID does not correspond to the own terminal, the command and the index data of the communication format are ignored (12S). If the ID corresponds to the own terminal, the command and the index data of the communication format are received (13S).

If the command is a voice signal by the MIC icon 11, the data is processed by the audio output unit and output through the speaker / headphone or the wireless transmitter (15S).

If the command is content data (index) by the content icon 12, the content data (index) is received (16S) and the audio and video signals corresponding to the index are read from the memory 202 ( 17S) The audio signal is output through the speaker / headphone or the wireless transmitter 205 through the audio output unit 203 and simultaneously displays the video signal on the display unit 206 (18S).

In addition, when the individual learning icon 14 or the power icon 15 is selected and transmitted from the lecturer terminal 120, the learner terminal 130 recognizes a command in the same manner as described above and the learning proceeds individually. (19S) or the terminal is turned off (20S).

As described above, only the textbook printed with the index and the control icon can be implemented without the need for a separate control device.

As described above, the learning system using the network according to the present invention has the following effects.

First, through the terminal for students to recognize the index printed on the textbook through the sensor to output and display the audio signal and video signal corresponding to the index, so that the learners can select and learn the desired content content alone. have.

Second, when the lecturer selects the textbook control icon through the lecturer's terminal, the contents of the voice or the textbook can be transmitted to the entire learners, groups, or individuals, and each learner's terminal can be controlled, thereby improving learning efficiency. You can.

Third, the learning room can be configured only by the communication line connected to the plurality of terminals and the modular jack, without having to provide a separate device can minimize the installation cost.

Fourth, if only the teaching materials and the terminal provided, you can learn in places other than the learning room.
