The invention relates to telegraph and can be used to train operators in a blind way of working on the keyboard of printing, type and coding apparatus.

The purpose of the invention is to increase the efficiency of learning by determining failures.

FIG. 1 shows a structural electrical circuit of the proposed simulator; in fig. 2 is a structural electrical circuit of the logic block in FIG. 3 is a structural electrical circuit for blocking failures; in fig. 4 is a structural electrical circuit of the comparison unit.

Telegraph operator simulator: a1T block 1 input answers, block 2 comparison, first 3 and second 4 blocks counting-1PCS, first 5 and second 6 decoders, first 7 and second 8 logic blocks, block 9 presenting training information, switch 10, block Formation of questions, block 12 commit failures, block 13 registration and elements OR 14.

The first block of counters contains the first 15 and second 16 ring counters, the first 17, the second 18, the third 19 and the fourth 20 switches.

The second block of counters contains the first 21 and second 22 ring counters, the first 23, the second 24, the third 25, the fourth 26, and the fifth 27 switches.

The question forming unit contains a pulse generator 28, a one-oscillator 29 and an AND 30 element. The registration block contains a counter 31, the number of responses, a counter 32, the number of correct answers, the OR element 33 and an indicator 34. Each logic block contains logic nodes 35 n 36, Each logical node contains a short pulse former 37, a counter 38, a prohibition element 39, and a delay element 40. The block for fixing failures contains an RS-flip-flop 41, a key 42 and a counter 43 in each channel. The comparison unit contains an AND 44 element, the first 45 and second 46 OR elements, a delay element 47 and a prohibition element 48.

The simulator works as follows.

Pre switch 10 is set to Digits, and on the block 3 counters: switch

17- to position P, switch

18- to the off position, switches 19 and 20 - to the on position.

The switch (not shown) of the counter 32 is set to position 100, and the switch (not shown) on the counter 38 is set to position 10.

The power is turned on, the generator 28 is started. On the board (not shown) of block 9, the Digits indicator is displayed, which instructs the learner to work on the numeric row of the keyboard of the response input unit 1. The learner presses the Reset button not shown,; setting the simulator to the initial state, and then the Start button, providing a pulse to the input of the single-vibrator 29. The pulse from the output of the single-vibrator 29 enters the input of the And 30 element, ensuring that pulses from the generator output 28 pass through it. The duration of the generator pulses 28 is hundreds of times shorter than the duration of the single vibrator 29, and the number of pulses fed into blocks 3 and 4 of the counters during the pulse duration of the single vibrator 29 exceeds the size of the ring counters 15, 16 and 21, 28 together.

The pulses from the output of the element I 30 through the element Sh1 14 and the switch 10 are fed to the input of the block 3 of the counters and through the switch 17 to the input of the series-connected meters 15, 16 (operating as one counter), ensuring its random state. At one of the outputs of the decoder 5, which corresponds to the state of the counter 15, 16, a single potential arrives at the corresponding input of the logic unit 7, at the input of the delay element 40 and at the input of the short pulse generator 37, causing its short pulse output, which is detected by the counter 38. The delayed pulse from the output of the delay element 40 through the information output of the prohibition element 39, to the control input of which the zero potential from the output of the counter 38 is applied, goes to the corresponding input of the block 9 of presentation of educational information, highlighting on the display of its digital p and the motor characteristic, for example P2 (second right), for one corresponding to this motor characteristic

from the types of failure fixation unit 12, to the first input of the corresponding RS flip-flop 41, ensuring the appearance of a single potential at its output, which is applied to the control input of the key 42,

The trainee, based on the highlighted motor characteristic (P2), performs movement on the digital row of the keyboard of the block 1 for inputting answers, i.e. makes a strike with the second finger on the key. When hitting the key, the contacts of the microswitch (not shown) close, which ensures the appearance of a pulse. This pulse arrives at the input of the element OR 46 and further to the input of the element 47 of the delay, the delay of which is equal to the duration of the response of the element OR 46.

If the trainee correctly performed the movement, then at the output of the element 44 there is a pulse, since at the second input of this element 44 there is a single potential from the output of logic unit 7, which entered through the element OR 45 at the control input of the prohibition element 48, to the information the input of which at a given moment is given a pulse from the output of the delay element 47, preventing the appearance of a pulse at the second synchronized output of the comparing unit 2, to the input of the recording unit 13, registering the correct answer in the counter 32, in the counter 31 - the first the answer. working out one movement) and to the second outputs of the RS-flip-flops 41, returning the latter to the initial state. At the same time, the impulse from the first output of the result of the comparison block 3 is fed to the input of the one-shot 29, the pulse from the output of which provides short-term repayment of the motor characteristic, translation of the counter 15, 16 into a new random state and subsequent highlighting on the digital board of the display 9 the next motor feature.

If the student did not correctly perform the movement on the digital row of the keyboard of the response input block 1, then the pulse is only at the output of the OR 46 element and through the delay element 47 and the prohibition element 48, the control input of which is fed to zero potential from the output of the OR 45, arrive at the input of block 13 regist2 6

p qi, recorded in the counter 31., the number of answers (proizvedenoenoe displacement), and the second outputs of the key 42

fixing a failure in accordance with your 43 hrs counter 43 - incorrect performance of the two trainees.

When appearing on the same output of the decoder 5 of a single potential 11th time, i.e. The 11th repetition of the same motor characteristic, at the input of the counter 38, a pulse (overflow) turns on, which, having entered the control input of the prohibition element 3, will prevent the unit potential from being fed to the corresponding inputs of the comparison unit 2, the training information presentation unit 9 and block 12 (fault notation. The same pulse from the output of the counter 38 through the elements OR 36 and 14 will go to the input of the counter 15, 16, ax); the movement of the unit potential at the input of the decoder 5 to the next row and

ensuring that the same motor characteristic is presented only a specified number of times (10 presentations).

When fixing the hundredth correct answer (ten for each digit)

at the output of the counter 32 for the Wits overflow pulse, which will illuminate the indicator 34 Stop, warning the trainer (teacher) to take readings from the counters 43 and 31. By

the number of failures made by the respective fingers is judged on the degree of development of the orientation skill on the digital keyboard row and the need to go over to processing in parts

(on the right or left side of the digital keyboard and on the keyboard), and by the number of answers - on the degree of fitness.

Similarly, the development of keyboard orientation skills is carried out.

characters (letters). For this purpose, switch 10 is set to the letter position, and on the block of 4 counters: switch 23 - to position P, switches 24, 25 and 27 - to position Off, switch 26 - to position On. The switch is not shown on the counter 32 is set to position 10, and the switch on the counter 38 is left in position 10.

On the scoreboard of block 9 presentations

of educational information the indicator of the letter is displayed, preceding the 11th student to work on his alphabetic keyboard of the block 1 input of answers.

The learner presses the reset button and then the Start, providing the output from the generator 28 to the input of the counter 21, 22 successively switched on pulses, which bring the latter into a random state. At one of the outputs of the decoder 6, corresponding to the given random state of the counter 21, 22, the potential that goes to the input of the logical unit 7 is unified, encrypting the presentation of the corresponding motor characteristic on the counter 38 of the corresponding logic node 35. The unit potential from the output of the logic unit 7 is fed to the corresponding input of the unit 9 of presentation, training information, highlighting on the board, for example, the horizontal row of the motor characteristic L4 (left fourth) and on the corresponding motor characteristic one of the inputs of the unit 2 block 12 commit failures.,

When a decoder 6 output unit appears on the same output 11 times, i.e. 11th repetition of the same motor characteristic, at the output of the counter 38 of the logic node 35, a pulse (overflow) is injected, which, arriving at the control input of the prohibition element 39, will prevent the supply of a single potential to the corresponding inputs of the unit 2 , block 9 presentation of educational information and block 12 fixing failures. The same pulse from the output of the counter 38 through the elements OR 36 and 14 will go to the input of the counter 21, 22, by moving the unit potential at the output of the decoder 6 to the next bit, i.e. ensuring that the same motor characteristic is presented only a specified number of times (ten presentations).

The actions of the student and the work of the blocks and elements of the simulator occurs

similar to the above (when released

Figures indicator).

According to the number of failures made by the respective fingers, the degree of development of the orientation skill on the alphabetic keyboard rows is determined and it is determined which parts of the keyboard need to be worked out first: the right or left side of the horizontal row keyboard, the entire horizontal row keyboard, right or left part of the keyboard characters.

The use of a trunner for training telegraph operators in comparison with the prototype improves the accuracy of the simulator, since it allows preliminary detection of the motor characteristics at which the trainees can fail, i.e. incorrectly determines either the location or the route. This allows the teacher to train the student on the part of the telegraph keyboard, where the most erroneous movements are allowed. The motor characteristics, according to which the trainee made a greater number of failures during further training, are presented to the trainee more (by setting the switch to the appropriate position on the corresponding counter 38). The trainings are converted into goal-oriented, time is not spent on working out firmly learned motor characteristics, thus reducing the time to master the keyboard at the initial stage of training.
