Description

The invention relates to communication technology and can be used to teach radio telegraphers to hearing aids during the Morse code mark learning phase.

The purpose of the invention is to expand the didactic capabilities of the device. .

The drawing shows a block diagram of the proposed device.

The device for teaching the radio telegraphists contains the student’s console 1, program setting unit 2, register 3, key 4, sound generator 5, electro-acoustic transducer 6, counter 7, decoder 8, key 9, group of keys 10, And elements 12 and delays, generator 13 pulses, comparator block 14 and Morse code reading unit 15.

Unit 2 of the program's task consists of an encoder 16 and switches 17, - 17.

The student console 1 contains the triggers 18 and switches,

The device works as follows.

When the device is turned on, the tape recorder of node 15 is started. The output of the generator 13 appears. A pulse arrives at the input of the counter 7 causing the first output of the decoder 1 to be applied to control the input of the key 10, preparing the circuit for entering the verbal image (chant and the correct answer circuit, i PDD switch 17 to the input of the encoder 1 6 of block 2, providing at its outputs the corresponding signs of the Morse code in the form of a binary formalized number.

At the same time, this pulse through delay element 11 enters the input of register 3, transfers the latter into parallel recording mode, and then, after passing through delay element 12, enters another register input, ensuring parallel recording of a formalized binary number from the outputs of the encoder 17 in register 3,

Upon receipt of pulses from the generator 13 output to the register 3 input, the binary combination is advanced, which from the register 3 output goes to the control input of the key 4. The sound vibrations produced by the generator 5 convert the single signals of the binary combination to audio signals (slime signals), . Those that go to the headphones 6. The student, having listened to the mark of the Morse code, identifies and presses the corresponding button on the console 10 on the nameplate of which the letter (digit) recognized by it is indicated.

If the trainee correctly identified the sign (pressed button 19, on the nameplate of which the letter ex is indicated, corresponding to the Morse code mark presented to it, then the next sign will be presented to it (for example, letter B, since when the button 19 is pressed, the unit potential from the output of the IS trigger the input to the comparison unit, the potential input to the other input jcoTppp- from the output of the decoder 8, and no signal at the output of block 14. If you are trained in the 1st non- REMOTE ENA ”(i.e. instead of button 19 pressed 19 ,,, on the "OIL; wild with the letter tf with corresponding to the Morse code symbol (f), the unit potential from the output of flip-flop 182 passes to the second input of block 14, to the Other input from the output of the decoder 8, the Zero potential is fed to the control input of the analog switch 9 and provides the like key; the sign values (the letter cj has a chant) from the first track of the magnetic tape through keys 10 and 9 to the headphones 6. The student will hear the verbal expression (the chant of the sign, the letter) of the wrongly identified one, while remembering the correct chant (aiwaa) . Upon receipt of the next pulse from the output of the generator 15, the triggers 18 of the console 10 are reset, 1 from the output of the decoder 1 2 appears at the second output and acts on the control input of the key lOj, and through the switch 172 to the decoder 16 ensuring the formation of the next jero Morse code signs, for example, the letter H. At the same time, the elements of the device work in the same way. After listening to the four different characters (letters, numbers), they are repeated.

If the student correctly recognizes the characters, the supervisor suggests the following group of characters, changing the position of the switches 17 by changing the answer buttons.
