Description

t

The invention relates to a communication technique, in particular, to devices for teaching radio telegraphists to hearing by ear, and is an improvement to the auth simulator. No. 1141441.

The aim of the invention is to expand the didactic capabilities of the simulator by turning on the visual memory in case of incorrect recognition of the auditory image of the Morse code mark by highlighting its structure.

The drawing shows a functional diagram of the simulator.

The wireless telegraph simulator contains a student console 1, a response analysis block 2, a control block 3, a 0LOCK 4 program, a memory register 5, a generator of 6 clocks, ana

the impulse from the output of button 12, passed through element 23 and element 20, goes to one inputs of registers 5 and 26, translates the latter into parallel recording mode, and passes through delay element 21, goes to other inputs, ensuring parallel binary recording the formalized number from the outputs of the encryption-fO pa 25 into registers 5 and 26 of memory. The clock pulses from the output of the generator 6 to the input of the register 5 produce a sign: recorded in it, to the control input of the key 15, ensuring the passage of the tone frequency from the output of the sound generator 8 to the headphones 9.

The student, listening to the sound image of the code mark presented to him

The key 7, the Morse sound generator 8.20, identifies it and presses the Headphones 9 and the unit 10 for displaying the structure of the symbol. Remote 1 contains ten buttons 11 answers and button 12 Start. Unit 2 contains elements AND 13, inverters 14, elements OR 15 and 16, inverter 17 and element BAN 18. Unit 3 contains a decoder counter 19, delay elements 20 and 21, and elements OR 22 and 23. Unit 4 contains switches 24 and the encoder 25. Block 10 contains a memory register 26, indicators 27, an analog key 28, and a one-shot 29.

The simulator works as follows.

The switches 24 set the signs that the trainee must work through the first training cycle. Turn on the power. 0 A counter decoder 19 and registers 5 and 26 are reset, generator 6 is turned on. The simulator is ready for operation.

The learner presses the button 12. The pulse from its output through the element 22 enters the input of the counter-decoder 19, causing the appearance of a logical unit at its first output. This

the corresponding button 11 on the remote control 1, on the nameplate of which the identified letter (number) is indicated.

Let the sign K (-) be presented, which corresponds to the appearance of the logical unit at the first output of the counter-decoder 19 and is stamped on the nameplate of the first button 11. If the trainee correctly identified the sign, then the impulse through the first element 13, which has unit, and element 15 enters the input of block 10, sets the register 26 to the initial state and 35 through element 22 to the input of the counter-decoder 19, providing a logical unit at the second output, which is fed to the input of the second element 13 through the second switch atelier 24 to the corresponding inputs of the encoder 25, ensuring at its output the formation of the next sign of the Morse code.

The impulse from the output of element 22, 5 passes through element 23 and element 20, enters the input of registers 5 and 26, translates the latter into parallel zatsisi mode, and passes through element 21, enters input peI

The impulse from the output of element 22, 5 passes through element 23 and element 2 enters the input of registers 5 and 26, translates the latter into parallel zatsisi, and passes through element 21, the input unit goes to the input of the first ele - 50 gistra 5 and 26, providing a record

ment I 13, through the first switch 24 - to the corresponding inputs of the encoder 25, providing at its outputs the formation of a Morse code sign in the form of a binary formalized number in which the point corresponds to 1, a dash - 111, and a pause between the elements of the sign - O. Simultaneously

in it, to the control input of the key 7, ensuring the passage of the tonal frequency from the output of the sound generator 8 to the headphones 9.

The student, listening to the sound image of the code mark presented to him

Morse identifies him and presses

the corresponding button 11 on the remote control 1, on the nameplate of which the identified letter (number) is indicated.

Let the sign K (-) be presented, which corresponds to the appearance of the logical unit at the first output of the counter-decoder 19 and is stamped on the nameplate of the first button 11. If the trainee correctly identified the sign, then the impulse through the first element 13, which has unit, and element 15 enters the input of block 10, sets the register 26 to the initial state and through element 22 to the input of the counter-decoder 19, providing a logical unit at the second output, which is fed to the input of the second element 13 through the second switch Spruce 24 to respective inputs of the encoder 25, providing at its output the formation of the next mark Morse code.

The impulse from the output of element 22, having passed through element 23 and element 20, is fed to the input of registers 5 and 26, has transferred the latter to parallel zatsisi mode, and has passed through element 21, is fed to inputs I

gistra 5 and 26, providing a record

they contain Morse code marks from the output of the encoder 25. The generator 6, through register 5, provides the feed of the mark to the headphones 9.

55 The student is presented with the following 1st (second) mark for identification.

If the trainee has incorrectly identified the sign, then the unit potential goes to the inverter 14, from the output of which the zero potential goes through element 16 to the prohibiting input of the element 18. As the outputs

elements 13, and accordingly, i vkho-g prompts - highlighting the structure of the de inverter 17, the potential is equal to the value. Introducing a visual image of a Morse code sign when an error is made allows the student, along with an auditory memory, to connect a visual memory, which makes it possible, using two forms of perceiving a sign, to memorize its auditory image more quickly and to reduce the time required for learning signs of learning. possessing predominantly f5 visual memory.

Liu, then from the output of the last unity potential is applied to the information input of the element 18. The pulse from the output

element 18 is fed to the input of the single-vibrator 29, ensuring the launch of the latter (on the 3rd), and to the input of block 3, performed overwriting of the same sign from the outputs of the encoder 25 into registers 5 and 26, i.e. misidentified sign. A single pulse from the output of the single-oscillator 29 applied to the control input of the switch 28 connects the inputs of the indicators 27 to the power supply pole and ensures their luminescence, since the inputs of the indicators 27 are connected to the outputs of the register 26 having a single potential, i.e. The illuminated indicators 27 repeat the binary structure of the Morse code sign recorded in register 26. Generator 6 provides repeated insertion of an incorrectly recognized sign into the headphones 9 by the student, while at the same time block 10 displays the structure of the sign in the form of dots and a dash.

The student visually perceives the structure, and by ear - the sound image
