The invention relates to autorunts and computational techniques, in particular to training devices, can be used for reviewing radio telegraphists by hearing at the Morse code feature study stage and is an improvement of the invention by author. cBi No. 1328838,

The purpose of the invention is to increase the efficiency of learning; The drawing shows a structural electrical circuit of the proposed device.

: The device for learning radio leggrafistov contains a pulse shaper 1, a counter 2, first and second decoders 3 and 4, a block 5 as compared to, a program setting block 6, rep, IS 7, a switch 8, a key 9, a sound generator 10, an electroacoustic converter 11, an inverter 12 student terminal 13 and a unit 14 changing the learning mode.

The pulse shaping unit is formed by the generator 15 and the first and second elements 16 and 17 of the delay. The program task block includes switches 18 and the encoder 19. The learner console contains the SO buttons, triggers 21, and banners 22.

The training mode changing unit is formed by the first and second counters 23 and 24, the RS flip-flop 25 ,. the first and second Keys 26 and 27, the first and the second ILI elements 28 and 29 and the delay element 30. (

The device works as follows.

Pre switch, for example, on the counter 23 is installed in the tenth, and on the counter 24 - in the second position (the capacity of the counters, after which the overflow occurs

When the power is turned on, the counter 23 is set to its original position and the trigger 25 is set to the second position, providing connection to the banners 22 of the console 13 via the power supply key 27 and the counter 24 blocking via the key 26.

At the first output of the generator 15, the grounding element 1 emerges a pulse, which affects the inputs of the trigger 21 of the console 13, sets the latter to the initial (zero) state, fixes the sign to the second (counting) input of the counter 23, and enters the input of counter 2, by

the appearance at the first output of the decoder 3 logical units. This unit is applied through the switch 18 to the input of the encoder 19, providing the appearance at its outputs of the corresponding Morse code sign in the form of a binary formalized number, to the input of the comparison unit 5, preparing the correct answer circuit.

Simultaneously, the pulse from the first output of the generator 15 through the delay element 16 is fed to the first input of the register 7, has transferred the latter to the parallel recording mode, and then, having passed through the delay element 17, goes to the second input of the register 7, providing a parallel recording of the formalized number from the output Dov encoder 19 to register 7.

The pulse from the first output of the generator 15 through the inverter 12 is fed to the second control input of the commutator 8, preventing the control signal from one of the outputs of the decoder 4, which determines the state of the encoder 19, from passing through the switch 8 to one of the banners 22.

Transparencies 22 are designed to display images that promote associative visual perception of the expression of Morse code signs. For example, the verbal exaggeration of the letter D sounds like this} do-mi-ki. This you, razheniyu corresponds to a banner with a picture of houses. The verbal expression of the letter G - g-ra-zik - corresponds to the image of a small car and so on for all the Morse code characters.

Q At the end of the pulse from the first output of the generator 15, the flow of advancing pulses c begins. its second output to the third (control) input of register 7 and the bihi

45 of the binary combination, which from the output of the register 7 enters the first (direct) input of the key 9.

When the pulse disappears at the first output of the generator 15, the output of the inverter 12 appears to impulse, allowing the control signal to pass from one of the outputs of the decoder 4 through the switch 8 to one of the banners 22, on which the image is highlighted, which facilitates the associative perception of the trainee expression of morse code signs.

key icon input 9, convert e binary binary signals into audio signals | which are fed to the electroacoustic transducer 11 for presentation to the learner.

The image on the banner 22 is displayed until the next pulse appears at the output of the generator 15.

If the trainees correctly identify the proposed Morse code mark, the image shines continuously until the next pulse is detected at the first output of the generator 15.

If the student does not recognize the character correctly, the image is displayed in blinking mode.

The sign recognition is made by learning 1 by pressing the corresponding button 20 of the console 13, and one of the triggers 21 is set to one. If the identification is correct, then at the output of the comparison unit 5 there is a zero potential, and if the identification is incorrect, a single potential. A single potential arrives at the second input of the learning mode measurement unit 14 — through the OR element 28 to the (zeroing) first input of the counter 23, returning it to the initial positon, to the first control input of the switch 8, providing the control signal from one of the decoder outputs 4 through the switch 8 to one of the transparento 22 in the preferred mode (the image flashes).

With the appearance of the next pulse at the first output of the generator 15, the triggers 21 are set to the initial (zero) state, the counter 23 records the presentation of the next sign (if the answer is correct) or the first (after the wrong answer), the counter 2 goes to the next state and logic a unit appears at the second output of the decoder 3.

The impulse from the inverter 12 prohibits the control signal through the switch {satator 8, the glow of the banner 22 stops.

The process then proceeds as described, but for another sign of the Morse code.

If the student correctly recognizes another ten characters of the Morse code, then at the output of counter 23, an overflow pulse appears, which

It goes to the input of the delay element 30, to the (zeroing) first input of the counter 24, returning it to the similar position and to the 8th input of the trigger 25, transferring the last to the first position. The key 27 is closed by disconnecting the banners 22 of the puppeta 13 from the power source, the key 26 is opened, the JO circuit is being prepared for passing the counter 24 impulses of incorrect response from the output of the comparison unit 5 to the counting input. A delayed pulse from the output of the element 30 delay return the counter 23 to its original position.

If the Morse code character's training in recognizing (answering) makes one mistake and then transmits ten characters without error, the overflow pulse from the output of counter 23 returns counter 24 to its original position and confirms that trigger 25 is in the first position — the drill continues to control mode.

If the student, after the first error, admits the second, the output of the counter 24 is an overflow pulse, which through the OR element 29 enters the R-input of the trigger 25 and transfers it to the second position. The key 26 is closed, blocking the counter 24, the key 27 is opened, providing

the feed to the banners 22 - the further training continues with a hint.

The use of the proposed device increases the efficiency of learning by automating the change of the training mode, depending on the ability of the learner to develop the ability to perceive the signs of Morse code by switching the device from prompt mode to mode.
