Description

The invention relates to computer science and computing, in particular to technical means of training, and can be used to control knowledge and attendance of classes by students.

The purpose of the invention is to increase the reliability and simplification of the console by reducing the number of communication lines.

FIG. Figure 1 shows the structure of the Harf console; in fig. 2 - time diagrams of his work.

The student's console contains a trunk 1 for the audience, a block 2 for inputting answers, a form of signal pulse 3, a register 4, a shaper 5 codes, a converter 6 codes, a comparison block 7, a synchronizer 8, a keyboard 9, switches 10 and 11, element 12, generator 13 (single pulse), trigger 14, pulse distributor 15, amplifier 16, shift register 17, integrator 18, Schmitt trigger 19, trigger 20, elements 2I-OR 21 and 22.

The student console works as follows.

After the student dials the response code on the keyboard 9 (eight keys) and simultaneously touches two hands of the switches 10 and 11 simultaneously with the fingers, the teacher presses the registration key in his console (not shown), sending control and synchronization signals to the student's console (FIG. 2, a). The generator 13 includes this console in the address address recording mode (Fig. 2, e), and the trigger 14 is reset (Fig. 2; k), allowing the code to be written to the register 4. Integrator tS and trigger

19, in the interval between the synchronization pulses, the amplifier 16 is switched to the reception (Fig. 2, p.

Upon the registration command of the teacher, addresses are received at the consoles (Fig. 2.6); at the beginning, during the registration of the presence, the addresses are duplicated.

In block 7, the code from the keyboard 9 (chained register 4 - element 21) is compared with the register code 17, if they coincide and when the keys of switches 10 and 11 are pressed, the signal from element 12 records the code of the learner in register 4 (FIG. 2, d), and triggers 14 and

20 are switched (Fig. 2.8), prohibiting the rewriting of the code in register 4. Modification of the address of the learner is carried out by switching the input power at the control input of the console.

When register 17 is filled with a repeated address, the process is repeated without switching trigger 14, since its counting input is closed by counting input after the first switch.

At the second switching of the trigger 20, the distributor 15 switches the amplifier 16 to transfer the response of the student (Fig. 2j, li).

If the transmission pulse coincides with the sync pulse, element 22 (S) will release the code reset pulse on the keyboard 9 (Fig. 2.0, J, K). At the same time, the indication of the code goes out, signaling to the student about the admission of his answer to the registration. During answers to questions from the lecturer, the student types on the keyboard 9 an answer with the possibility of correcting it before pressing the key of the switch 11, which is achieved by the open element 22 (aX When registering the answer, the learner pressing the key of the switch 10 closes the element 22 (and then the switch 11 key is pressed). At the instruction of the teacher, the code on the keyboard 9 is reset if the address recorded at the beginning of the lecture in register 4 coincides with the correct answer code.

If the answer is incorrect, the signals from the console do not appear, and the reset of the keyboard 9 does not occur, which signals the learner that the answer is incorrect.
