And a channel 4 video controller 108 and an audio controller 109 for controlling 4 video and audio. In addition, a dialogue teacher headset 80 for communicating with students is attached, so that the teacher can explain the textbook to the students, and the dialogue line switching function can be used to communicate not only with the entire student but also with a predetermined group of students or a specific student. To make it possible.

In addition, there is an external video / audio signal controller that transmits textbook video and audio signals to a large color television as an external video device and a teacher computer, in which a textbook signal transmitted to the teacher computer is associated with channel 4, which is a dedicated channel for teacher textbooks. This linked signal can be used as a teaching aid.

The configuration of the digital switching element 102, which is the most essential part of the main regulator, will be described with reference to FIG. First, the switching unit configuration is formed from the first switching unit configuration (1022-1) to the 28th switching unit configuration (1022-28), the switching unit components are internally four digital switching core logic elements are the main axis, Each of the switching logic elements has two sets of receiving input data four-line signals, and two data selection control signal lines for inputting only one signal of the four-line signals of each set are input. The data selection control signal is also input to other groups at the same time so as to simultaneously output one selected signal of each group, and at the same time is formed as a portion for outputting the selected two-line output data. The truth table for a set is shown in Table 2, which shows the truth table of the four-line two-channel signal selector (the predetermined example of '1022-11' switching in FIG. 3).

In the above table, L denotes a low level signal, H denotes a high level signal, and X denotes a don't care.

Looking at the actual switching unit configuration with reference to the function of the switching element, first from the output portion of the NTSC-VGA signal converter that converts an NTSC signal into a VGA signal as an input data signal to the first switching element 1022-11. One pair receives the 'R signal' (red signal) four lines (R-OUT1 to R-OUT4) of the VGA video signal, and the other pair receives the 'G signal' (green signal) four lines (G-OUT1 to G-OUT4). ) And two selection control signals (A1 and B1 signals) from the microcomputer (101 in FIG. 2) that allow the simultaneous selection of one of these four lines. -OUT-1, G-OUT-1) are output respectively. Similarly, the second switching element 1022-12 has four 'B signals' (blue signals) (B-OUT1 to B-OUT4) and four horizontal synchronization signals (H-SYNC1) from the NTSC-VGA signal converter, respectively. H-SYNC4) are output and output signals (e.g., B-OUT-1 and H-SYNC-1) are output in accordance with the selection control signals A1 and B1 signals commonly connected. Similarly, the third switching element 1022-13 receives four vertical synchronization signals (V-SYNC1 to V-SYNC4) from the NTSC-VGA signal converter and outputs the output signal (for example, V according to the selection control signals A1 and B1 signals). -SYNC-1) is output. The fourth switching element 1022-14 has a switching characteristic different from that of the first, second, and third switching elements, and the fourth switching element 1022-14 has an input data of eight input line signals in accordance with the selection control signal three lines A1, B1, and C1. It is an element which selects and outputs one signal, and the truth table of this is shown in Table 3.

In the above table, L denotes a low level signal, H denotes a high level signal, and X denotes a don't care.

The fourth switching element 1022-14 should select one of the six audio signal lines AUDIO1 to AUDIO4, CAS1, and CAS2 according to the selection control signals A1, B1, and C1. Since the number of input data lines is insufficient as a four-line input element such as a three switching element, an additional fourth switching element 1022-14 having eight input data lines is adopted. Thus, R-OUT-1, G-OUT-1, B-OUT-1, and H- are simultaneously output from the first, second, and third switching elements according to the control signals A1 and B1 signals, which are common signals, in a switching unit configuration. SYNC-1 and V-SUNC-1 are joined to one VGA video signal terminal 1023-1 and connected to a predetermined VGA video display monitor to perform selective switching operation of textbook video from student side. The teaching sound for the teaching material selected from the four switching elements 1022-14 is also selected. In addition, the text sound is secured by adding two audio cassette teaching materials separately from the video teaching material.

In addition, the channel number of the channel selector button of the student's auxiliary controller is inputted to the main controller in the RS-485 serial communication data connected to the main controller, and the microcontroller of the main controller receives the data and processes it. It is transmitted in a switching unit configuration of 3 degrees so as to be used as a common selection control signal (A1 and B1 signals) which are teaching channel selection signals of the first, second, third and fourth switching elements. In total, as shown in FIG. 3, the total number of switching units is 28 sets, which are connected 1: 1 to 28 student monitors. In other words, considering the total number of 56 students, two students are assigned to each monitor, which means that two sets of learning forms are basically formed. It follows the form. On the other hand, textbook listening, teacher-student conversation, and textbook channel selection functions must correspond 1: 1 with students, so the auxiliary controller that controls this function is assigned to 56 students.

The student side adjuster (20-1 to 20-56 in FIG. 2) in the present invention will be described in detail with reference to FIG. As shown in FIG. 4, the auxiliary regulator 1 (20-1) must first receive (transmit and receive) command data from the main regulator, so to implement this (RS-485 communication control element 20-12 from the main regulator to implement this). Receive the command data, and these received data are internally introduced into the auxiliary regulator control element 20-11 via the 'Com-B0' and 'Com-B4' signal lines, and the auxiliary regulator control element 20- 11) directly assembles and processes these serial data and performs a predetermined command function, where the remaining signals 'Com-B1' and 'Com-B5' of the RS-485 communication control element 20-12 are The 'COM-B2' and 'Com-B6' signals of the auxiliary regulator 2 (20-2) are of the auxiliary regulator 3 (20-3), and the 'Com-B3' and 'Com-B7' signals of the auxiliary regulator 3 (20-3). Connected to the auxiliary regulator control elements 20-21, 20-31, and 20-41 of 20-4, respectively, and the auxiliary regulators 2, 3, and 4 (20-2 to 20-4) are auxiliary regulator 1 (20-). 1) and Only auxiliary controller 1 (20-1) is responsible for communicating with the main controller (the 'main auxiliary controller', which is in communication with the main controller, and the secondary controller communicating with the main auxiliary controller. Is called the "sub auxiliary regulator".

As described above, since the sub auxiliary regulators 2, 3, and 4 (20-2 to 20-4) are connected and operated by serial communication to the main auxiliary regulator 1 (20-1), four of these auxiliary regulators are 1 during initial installation. A four-pole on-off dipswitch 20-17, which is set to retrofit and connected to the RS-485 communication control element 20-12 of the auxiliary regulator, is used to set the identification number of one set of these auxiliary regulators. . In Fig. 4, the auxiliary regulator control elements 20-11 to 20-41 are responsible for the core functions. First, data is received from the RS-485 communication control element in serial communication, and then assembled and processed. Function to perform command data to listen to textbook sound or to select whether to talk or not, and read the key value of the connected keypad (20-16 to 20-46) to call a teacher (Call button), adjust the volume of the headset (volume button), It also performs functions such as textbook channel selection (channel button) and transmits various status changes or commands to the main controller to inform the student's situation. It receives volume control key values and generates volume control data according to the values, and flows them into the volume control element to enable electronic volume control of the headset, and operates the 7-segment display element to operate the current teaching material channel number. When the dialogue line selection or teaching material selection command is inputted through the serial communication from the teacher side, they are assembled and processed, and control data is generated and flowed into each selection element to directly control them.
