The valve 15 includes a prohibition element 63, a one-shot 64, a trigger 65 and a delay element 66.

The simulator works as follows.

Beforehand, in the imaging unit 9, a sequence of presentation of characters is established in accordance with the text of the radiogram, Power is turned on. The counters and registers are reset, triggers 65-59 are in the zero position (Fig. 12 a, b). Generator 8 starts. The simulator is ready for operation.

The operator starts to transmit text

0 radiograms. The impulse of the first element of the sign from the output of the telegraph key 1 through the element 63 is fed to the input of the one-vibrator 64, causing a short single pulse to appear at its output. This impulse

5 is fed to the input of the trigger 65, translating it into a single state (Fig. 12a). A single potential from the output of the trigger 65 is applied to the control input of the element 63, preventing the flow of the following

0 elements of the sign to the input of the one-oscillator 64. The pulse from the output of the one-shot 64 through the information input of the element 18, to the control input of which zero potential from the input of the register 17 is fed, goes to

5 input shaper 9, providing extension with its output binary combination of the sign of the Morse code corresponding to the transmitted first character of the text of the radiogram. This combination is filed on

0 register 25 by means of clock pulses coming from the output of the imaging unit 9 through the element And 55, to which the unit potential is fed from the output of the inverter 52, and the element OR 53 to the input of the register 25,

5 is recorded therein at a speed twice the operator’s transmission rate.

At the same time, the elements of the transmitted mark (pulses) from the telegraph output

0 key 1 is fed to the input of the driver 7, to the outputs of the register 33, each element of the sign in which is written to the corresponding bit, providing the output at the outputs of the register 33 of single potentials that are applied to the inputs of the And 34 element, and through block 6, on which clock (synchronizing) pulses come from the generator 3 output, are fed to the information input of the register 26. The attack pulses from the output of block 6 through the switch 11 to the shift input of the register 26, in the last record of the binary combination transmitted the sign in which the point corresponds to 1,

5 dashes - III, and the pause between the elements of the sign.

Code combinations of characters from the outputs of registers 25 and 26 are applied to the first inputs of the corresponding elements AND 27 and 28, respectively. Stop recording

the control character in the register 25 is provided by supplying a single potential from the output of the element OR NOT 50 to the control input of the element 51.

Upon completion of the transmission of the sign of the radio program, in which there are no more than five elements, the zero potential at the output of element 34 is unchanged. At the output of the driver 7, a pulse of a pause (FIG. 12) is applied to the Wits, which is fed to the input of the trigger 65, ensuring the appearance of a zero potential at its output (FIG. 12 a). The zero potential from the output of the trigger 65 is applied to the block 6, stopping the supply of clock pulses to the input of the register 26, is applied to the control input of the element 63, preparing a circuit for extending the next control sign from the former 9. A pause pulse from the output of the former 7 simultaneously goes to register 33, having set it to its initial state, to the input of element 32, through the OR element 19 to the counting input of counter 15, ensuring the appearance of a single potential at its first output, which is applied to the input of register 17, to input Ci the next (clock) and input element 66, the delay time of which is longer than the delay time of element 32.

The delayed pulse from the output of the element 32 enters the inputs of the elements And 27 and 28, ensuring the reading of information from the outputs of the registers 25 and 26 to the inputs of the group EXCLUSIVE OR 29.

If the operator correctly transmitted the sign, then the potential of the elements 29 does not change at the outputs of the element OR 30 — the potential is zero. The delayed imuls from the output of the element 66 enters the installation inputs of the registers 25 and 26, returning the latter to the initial position. Similarly, all five characters of the group are recorded. When the sixth character (the first character of the second group) arrives, a single potential appears at the sixth output of the counter 16, which enters the input of the delay element 21. A pulse from the output of the element 21 is fed to the input of the delay element 22 and through the OR element 20 to the embossing input of the counter 16, setting the latter to its original state. The pulse from the output of element 22 through the element OR 29 is fed to the counting input of counter 16, ensuring the appearance of a single potential at its first output, i.e. fixing the first character of the second group, etc. (the process is repeated as described above).

If the operator made a mistake when transmitting the sign, then at the output of one or more elements 29 a single pulse is passed through the element 30 and element 31, to the control input of which zero potential from the sixth output of the register 17 is fed to the input of counter 4, which will fix an error in the transfer of the mark.

At the same time, the pulse from the output of the element 31 (Fig. 12 g) is fed to the C input of the trigger 59, transferring it (Fig. 12 b) to a single position (preparing a circuit for picking up the characters during an incorrect transmission) through the elements 57 to the control inputs which supplied zero potential from the last outputs of registers 56 to the control inputs of switches 10 and 11, respectively, ensuring the supply of time stamps applied to their second inputs from the third output of generator 8 to the shift inputs of registers 25 and 26 (Fig. 12 d), ensuring the advancement of information (binary code the new combination of Morse code characters) from their outputs to the information inputs of registers 56 (control and transmitted), respectively, and their entry in the last pulses applied to the clock inputs of registers 56. The pulse frequency from the third output exceeds the pulse frequency from the second generator output 8 a hundred times.

The occurrence in the last output of each of the registers 56 of a single potential that is applied to the control input of the corresponding prohibition element 57 will ensure that the binary combination of the Morse code sign in register 56 is stopped.

If the operator noticed a mistake during the transmission of the sign, then immediately after the pause, the interruption is transmitted; Another six points, and then first signs of this group.

Let the operator give two characters in the group correctly, and in the third one I made a mistake and noticed it. After a pause following the third character mistakenly transmitted, the operator transmits the stoppage. At the outputs of the register 33 - unit potentials. A single pulse from the output of the element And 34 (Fig. 12 e) enters the counter 35, fixing the error correction, through the element OR 19 - to the counting input of the counter 16, writing a fourth unit to it, to the input of the delay element 23 and to the input YI of the register 17 by translating the latter into parallel recording mode. The delayed impulse from the output of element 23 will go to input Ca of register 17, ensuring that units are recorded in the second to fifth digits of register 17. The delayed impulse from output of element 24 through the element OR 20 will go to the roundabout input of counter 16, returning it to its original state .

At the same time, the pulse from the output of the element 34 is fed to the P input of the trigger 56, setting the latter (FIG. 12 b) to the zero position. The display of the incorrectly transmitted sign will not occur, because the trainee has noticed the mistake made

An impulse, pauses (Fig. 12c) from the output of the imaging unit 7, arriving after resetting the counter 16 to its counting input, will ensure the appearance of a single potential at its first output and move the units in register 17 to the third to sixth bits, ensuring the supply of a single potential from the sixth output of the register 17 to the control input of the element 18. This will prevent the arrival of a short pulse from the output of the single-vibrator 64 through block 2 to the input of the imager 9 when the operator passes the following characters, i.e. first to fourth digits of the repeated group.

A single potential applied to the control input of the element 31 will prevent pulses from passing to counter 4 if the group signs are interrupted and re-transmitted, and the delayed pulse from the output of element 66 will return registers 25 and 26 to their original position.

After transferring the sign following the transmitted one with an error, a zero potential is established at the output of the register 17, which is fed to the control inputs of the elements 18 and 31, restoring the coordinated operation of the device.

When transmitting the next character of the group, a short pulse from the output of the one-shot 64 through element 18 is fed to the second input of the imaging unit 9, providing the presentation to block 3 of the next control sign corresponding to the sign of the transmitted text of the radiogram.

If the operator did not notice the error, i.e. If the sign did not follow the incorrectly transmitted sign, then the pause pulse (Fig. 12c), after transmitting the next sign, will pass through the element 60, to which the unit potential from the output of the trigger 59 is fed, to the input of the one-vibrator 61 (Fig. 12) ) by running the last one. A pulse from the output of the one-shot 61 with a duration of 2 s (Fig. 12h) will open the key 62, providing a luminescence of the LEDs 58, repeating the binary structure of the points, dashes and pauses between them of the control and the transmitted Morse code characters recorded in registers 56.

The operator, seeing the display of characters, corrects the error.

The use of the invention in devices for training operators expands

the didactic capabilities of the simulator and increases its efficiency, because it allows you to display the structure of Morse signs, in which mistakes are made,

seen by the trainee when transmitting key text from a sheet.

According to the total number of errors made, the number of recorded searches during transmission of radiograms and their subsequent change in the course of training, it is judged on the success (failure) of the Morse code transfer from the sheet, while displaying the structure of the sign with an error and the check mark makes it possible to eliminate unnoticed errors in the structure of the sign and identify the cause of their occurrence. Getting rid of errors in a timely manner improves the quality of transmission and reduces the time spent on working out the transmission of text.
