On the other hand, Figure 4 is a schematic block diagram of a network education system of the classroom according to another embodiment of the present invention, Figure 5 is a schematic diagram showing another embodiment of the appearance of the classroom in which the network education system of the present invention is installed 4 and 5, according to another embodiment of the present invention, the RF transceiver 30 is connected to the main server / gateway without directly connecting the teacher PC 20 and the RF transceiver 30. 10 and the teacher PC 20 can be configured to be connected to the connected premises network.

In this case, the teacher PC 20 and the e-book terminal 40 communicate with each other via the path of the teacher PC 20 ↔ premises communication network ↔ RF transceiver 30 ↔ e-book terminal 40.

According to this configuration, even when the teacher PC 20 is off, each student is connected to the e-book terminal 40 through the RF transceiver 30 to the internal communication network and other students' e-book terminal 40 Communication may be possible, and the main server / gateway 10 may be connected to an external network such as the Internet.

Now, a method of conducting education using the network education system of the classroom configured as described above will be described.

First, when the teacher applies power to the teacher PC 20 and the RF transceiver 30 to operate, the operating system is loaded and initialized on the teacher PC 20, and the RF transceiver 30 is in an operating state, and the teacher PC 20 is in a state capable of communicating with the e-book terminal 40 possessed by the students in the classroom through the RF transceiver (30).

In this case, the teacher PC 20 may transmit a signal for calling attendance to each e-book terminal 40 in the classroom through the RF transceiver 30, the call signal identified by each e-book terminal 40 It may be assigned a number and transmitted separately, or a call signal may be simultaneously transmitted for an unspecified number without an identification number.

The call signal transmitted to the RF transceiver 30 directly from the teacher PC 20 or through an internal communication network is modulated into an RF signal by the RF transceiver 30 and each e-book terminal 40 through the RF relay antenna 31. Are transmitted to the network (S1).

As described above, the RF signal transmitted from the RF transceiver 30 through the RF relay antenna 31 is received by the RF communication module 42 through the RF antenna 41 of the electronic book terminal 40, and the RF communication module ( The demodulation is performed on the original attendance call signal at 42 and input to the processor 47 via the I / O controller 46.

Accordingly, the processor 47 outputs a signal corresponding to the attendance call signal, which is automatically performed by a pre-programmed algorithm or instructs the student to answer the call through the key input unit 44. The response signal may be output only when is input.

The signal responding to the attendance call output from the processor 47 includes an identification number on the network assigned to each e-book terminal 40, and the RF communication module 42 via the I / O controller 46. Is passed on.

The response signal transmitted from the processor 47 through the I / O controller 46 is modulated into an RF signal in the RF communication module 42 and then transmitted through the RF antenna 41, and the electronic book terminal 40 The RF signal transmitted from the RF signal is received by the RF relay antenna 31 and demodulated as a response signal in the form of a wire through the RF transceiver 30 and then transmitted to the teacher PC 20 directly or through an internal communication network (S2).

The teacher PC 20 receives the response signals from each of the e-book terminals 40 and determines the names of the students who attended by the identification numbers included in the response signals, and displays the names of the students who answered the attendance of the display apparatus. It is displayed on the screen.

The list of attendance students may be stored in the form of a database, such as an auxiliary memory device of the teacher PC 20, and the list of attendance students stored in the teacher PC 20 may be stored in the main server / gateway through the campus communication network. 10 may be transmitted and stored.

That is, using the present invention, without having to call out the list of students as in the prior art, when the teacher operates the key of the teacher PC 20 once, whether the student's attendance can be automatically checked and stored in the database. have.

In addition, the teacher can transfer the test questions that are suddenly conducted or regularly conducted during the learning or the content or tasks for the learning materials from the teacher PC 20 to each e-book terminal 40, from the teacher PC 20 Learning materials, assignments or test questions transmitted to each of the e-book terminals 40 may be temporarily stored in the RAM 49 in the e-book terminal 40 or may be stored in the flash memory 50. 43, a memory pack for storing data (e.g., a flash memory pack) may be inserted to be stored in the inserted memory pack (S3).

And, the students can transmit the results of solving the task or test questions from the e-book terminal 40, respectively, to the teacher PC 20 through the RF signal (S4), from each student's e-book terminal (40) The result of solving the task or test question received by the teacher PC 20 is stored in the teacher PC 20 and transmitted to the main server / gateway 10 through the local communication network and stored in the main server / gateway 10. May be
