Description

The invention relates to automation and computing, in particular to training devices, and can be used in the preparation of radio telegraphists for recognizing signals from the background of interference at different stages of training. The purpose of the invention is to expand the didactic capabilities of the device and improve the quality of radio telegraph training by detecting and attaching the skills of distinguishing signals from the speed of wiring and from the training time of highly qualified instructors. The drawing shows the structure of the device | for the training of radio telegraphists. The device contains a pulse shaper 1 (with manual adjustment of the pulse frequency), a shaper 2 clock pulses (with automatic adjustment of the pulse frequency), a block 3 of the training program tasks, including shapers and 5 Morse codes, a control block 6, a switch 7, blocks 8 and 9 present information, generator 10 (sound-tonal frequency), block 11 for analyzing responses and recording the result, bullets 12 for the operator, ring shift register 13 and indicator 14. Block 6 contains drivers 15 and 16 pause pulses, the elements of And 17 and 18 and the former 19 of a random sequence of pulses. Switch 7 contains elements AND 20, 21, 22 and 23, trigger 24 and elements OR 25 and 26. Blocks 8 and 9 contain analog switches 27 and electro-acoustic transducers 28. Block 11 contains elements AND 29, 30 and 31, elements OR 32 and 33, the BAN element 34, the counter 35 correct answers, the counter 36 answers, the counter 37 cycles and the indicator 38 First stage, Second stage. The operator panel 12 includes a start button 39 and buttons 40 and 41 Answer. When working with a device, the subject is suggested to choose from two simultaneously transmitted sequences of Morse code characters, differing in transmission speed, by means of presented sound samples, to determine the sequence with the nominal reception speed reached by the student, noting the location of each character of this sequence by pressing the corresponding button. Preparing the device for operation is reduced to installing in each driver 4 and 5 using switches (not shown in the drawing) identical sequences of different Morse code characters, one of which, presented at a transmission rate equal to the nominal speed and a friend, having a lower transfer rate, is disturbing. The manual regulator simultaneously sets the pulse frequency of the former 1 equal to the nominal speed of the student’s reception and the minimum pulse frequency of the former 2 that is 5 g / min less than the nominal speed of the student’s reception, for example, 18–13 g / min (selected from the speeds 13–8, 14 -9, ..., 22-17 g / min). The device works in the following way. When power is supplied, the counters 35, 36 and 37 are reset, the shift register 13 and the indicator 14 are in the first position. The generator 10 starts up, giving the sound frequency to the inputs of blocks 8 and 9. On the indicator 14 the first light is on, indicating the difference between speeds of transmission of signs equal to 5 g / min. Suppose there is a single potential at the first output of the trigger 24 at a given time, and zero at the second output. The single potential from the first output of the trigger 24 is applied to the second inputs of the elements 20 and 22 and ha of the input of the element 29 of the block 11. The device for presenting identification signals (signs) for recognition is launched. Press the Start button 39 to start. The pulse from its output goes to the inputs of the formers 1 and 2 and starts them, as well as to the inputs of the formers 4 and 5, ensuring that the first signs in each of them are prepared for extension. Clock pulses from the output of the imager 1 are received on the formation31

Body 4 with a higher frequency than clock pulses from the output of the imaging unit 2 to the imaging unit 5. Therefore, sequential movement of the binary code combination of the sign from the output of the imaging device 4 is realized at a higher speed (18 g / min) than from the output of the imaging technology 5 ( 13 g / min. Code combinations of characters from the outputs of the formers 4 and 5 are supplied to the inputs of the formers 15 and 16 and inputs of the elements 20 and 22, respectively. From the output of the latest combinations of characters, the control inputs of the keys 27, respectively, are sent to the information inputs of the nocTjmaeT tone frequency from the generator 10 output. In the electroacoustic transducers 28 sound melodies of various transmission speeds sound.

The student, listening to both signals at the same time, determines which converter 28 has the melody of the Morse code sign at a higher speed (the nominal rate of the learner’s reception) and presses the corresponding button — 40 or 41.

When the answer is correct (in our example, the main signal goes to block 8), the pulse from the output of button 40 goes to the first input of element 29 to the second input of which a single potential from the first output of trigger 24 is fed, and through element 32 to the input of counter 35, which will fix the correct answer. Simultaneously, the pulse from the output of the button 40 passes through the element 33 and enters the information input of the element 34 and the input of the counter 36. The counter 36 will record the answer.

During the pause between the signs at the outputs of the formers 15 and 16, pulses appear and enter the inputs of elements 17 and 18. The pulse from the output of element 18 turns off the formers 1 and 2. If at that time from the output of the former 19 also comes 1 17, then a single potential appears at its output, which, arriving at the counting input of trigger 24, changes its state: at the first

output will be Oh, on the second exit 114II i.

Since the forbidden entry element 34 is fed to zero potential

from the output of the counter 36, after the student answers his pulse, from his output goes to the second inputs of shapers 4 and 5, translating them to the next position (on the second sequence characters), and includes shapers 1 and 2, ensuring the extension of the second characters. from the outputs of the formers 4 and 5. With 10, the sign of the main sequence will be fed to the second electroacoustic transducer, and the disturbing one to the first one.

The student, listening to the signals of both 15 sequences, again locates the main character and presses the corresponding button.

If the trainee is correctly identified. all the signs of the main sequence, then the outputs of counters 35 and

36, the capacity of which is equal to the number of characters in the sequence, overflows appear. These pulses applied to the inputs of the element 31, 25 provide the appearance of a pulse at its output, which, having entered the input of register 13, transfers it to the second position by changing (increasing) the frequency of the following JQ pulses from the output of the generator 2

and 1 gr / min. In the indicator 14, a second light comes on, which indicates that the difference in the transmission rates of the Morse code characters is 4 g / min. The overflow pulse from the counter of the counter 35 simultaneously enters the input 34 of the bans and prevents the starting of the drivers 1 and 2 and the translation of the drivers 4. and 5 to the first position, and also returns the counters 35 and 36 to the initial state. , The student presses the button again; 39 Starting and, similarly to the above, it identifies the signs of the main sequence at a difference in transmission speeds of 4 g / min. With the correct identification of the main sequence in the second cycle, go to the third cycle, 50 reducing the difference in transmission speeds each time by 1 g / m.

If the answer is incorrect, the last one will be fixed only by the counter 36 and at the end of the cycle (predicting the whole sequence) only one input of the element 31 will have a unit potential. Therefore, register 13 does not change its position.
