Description

00 QO

The invention relates to irradiating devices designed to train operators to work blindly on the keyboard of printing (telegraph) dialing and coding apparatus.

The purpose of the invention is to expand the didactic capabilities of the simulator.

FIG. 1 shows the structure of the simulator; in fig. 2 - functional block comparison circuit.

The telegrapher simulator contains a response input block 1, performed on microswitches in the form of a keyboard of a telegraph apparatus, a comparison block 2, a block of 3 counters for generating code (digital) information, a block of 4 counters for generating character (literal) information, the first 5 and the second 6 degiifra - tori, block 7 elements And, block 8 before) - occurrences of educational information (symbols), switch 9, block 10 of dynamic (random) wave generation, timer 11 and block 12 of registration.

The outputs of block 1 are connected to the corresponding inputs of the first group of block 2, the inputs of the second and third groups of which are connected respectively with the inputs of the first and second groups of block 7 and connected to the output of the first 5 and second decoders. The outputs of block 7 are connected to the corresponding inputs of block 8. The inputs of decoders 5 and 6 are connected to the outputs of blocks 3 and 4, respectively, whose inputs are connected to the first and second outputs of switch 9, respectively. The output of block 10 is connected to the inputs of switch 9 and block 11, the first output which is connected to the input of block 1 and the third input of block 7. The second output of block 11 is connected to the input of block 10, and the third input is connected to the third input of block 12, the first and second inputs of which are connected to the corresponding outputs of block 2.

Unit 1 has keys with buttons, microswitches, “Start to Reset and logical key” buttons, ensuring the connection of a single potential to the contacts of microswitches when a signal is received from block 11 (not the choice: cho).

Blocks 3 (4) include ring counters (with pre-installation) i; switches (not shown).

Block 7 contains two-input e; 1meme -yy and 13.

Unit 10 contains a pulse generator 14 (with a high frequency of following), a single vibrator 15 and an element 16.

Block 11 includes an adjustable one-shot 17, the pulse duration (of a single potential) at the output of which is varied with a switch from 15 to 1 s, in jumps equal to 1 s, differentiation element 18 and delay element 19.

Block 12 includes a counter of 20 numbers of correct answers, a counter of 21 numbers of incorrect answers, a counter of 22 numbers presented characters (with an adjustable number of counts) and indicator 23 "Stop.

Block 2 contains elements And 24, the first and second elements OR 25 and 26, the element And 27, the first and second elements NOT 28 and 29 and the element 30 delay.

0 Block 8 on its board copies the location of the keyboard key block 1.

The device works as follows.

Previously, the switch on the counter 22 is set to the position “50, with the switch of the pulse duration of the single vibrator 17 to the position 15c, switch 9 to the position Digits, and the switch in block 3 to the position providing connection of the right side of the digital row keyboard 0 on block 8.

Turn on the power. The generator 14 is started. On the display panel of block 8, the indicators “Figures and“ Rights prescribing the student to work on the right side of the digital row of the keyboard of block 1 with his right hand are displayed.

The operator presses the “Reset” button, sets the counters to the initial state, and then the “Start” button, providing a pulse to the one-shot 15-block 10. The pulse from the output of the one-wave 15 goes to the input of the AND 16 element, ensuring passage through the last pulses from the output of the generator 14. The duration of the pulses of the generator 14 is hundreds of times shorter than the pulse duration of one- 5 vibrators 15, and the number of pulses entering blocks 3 and 4 during the pulse duration from the one-vibrator 15 exceeds the size of the block counters.

The pulses from the output of the element 16 through the switch 9 are fed to the input of the block 3, 0 ensuring the random state of its counter, and pa the input of the block 11. The first pulse from the output of the element 16 starts the one-shot 17. The pulse of 15 seconds duration from the output of the one-shot 17 enters to the input of the differentiation element 18, to the input of the block 1, ensuring the opening of the key in it and the supply of a single potential to the contacts of the microswitches (keys), and to the third input of the block 7, supplying the unit potential to the second inputs of the And 13 elements. At the same time on one of the out The decoder 5 has corresponding to this random state of the counter of block 3, a unit potential is applied to the first input of the corresponding element AND 13 of block 7 (the second input is fed to the unit potential from the first output of block 11), highlighting on the digital p yes block 8 motor characteristic, for example, P4

(fourth right) and one of the inputs of block 2 corresponding to this motor characteristic.

The trainee, according to the highlighted motor characteristic (P4), performs movement on the digital row of the keyboard of block 1, i.e., makes a stroke with the fourth finger of the right hand on the key.

If the trainee correctly identified and performed the movement in a timely manner, then when hitting the key, the contact is closed with a microswitch, which ensures the appearance of an impulse. This impulse goes to the input of element AND 24 of block 2 corresponding to this key, and through element OR 26 to the input of element 30, the delay time of which is equal to the response time of elements 24 and 28. At the output of element 24 there is a pulse (because the input has a unit potential from the output of the decoder 5), which will go through the elements 25, 28 and 29 to the first input of the block 12, fixing the correct answer in the counter 20. At the same time, the zero potential (pulse) from the output of the element NOT 28 will be fed to the second input of the element AND 27. The delayed pulse from the output of the element 30 will go to the first input of the element 27, but will not go further (zero potential at the second input)

At the end of the pulse from the output of the single-vibrator 17, the presentation of the motor characteristic symbol (MX) on the display of block 8 is stopped, the key in block 1 is locked, preventing the pulse from the microswitch output from being pressed when the key is pressed. The falling edge of the pulse arriving at the input of element 18 will cause the appearance at its output of a short pulse that arrives at the input of counter 22, recording the presentation of the MX symbol, and the input of element 19. The pulse delayed by the pause time between the presented MX characters from the output of element 19 will go to the input of the one-shot 15 block 10, launching the last one and providing a new random state of the counter in block 3 and the subsequent flashing on the digital row of the scoreboard block 8 of the next motor characteristic.

If the learner incorrectly, but timely performed the movement on the digital row of the keyboard of block 1, then the pulse is only at the output of element 26 and through elements 30 and 27, since a unit potential from the output of element 28 is applied to its second input, goes to the second input block 2, fixing in the counter 21 the wrong answer.

If the trainee struck the corresponding key of block 1 in the absence of the MX symbol (fading) on the display of block 8, then at the outputs of the result of block 2 there will be no pulses (a single

Judging by the number of correct and incorrect answers and the number of prolonged decisions (answers that were not completed at a given time), the degree of development of the high-speed orientation skill on the digital row of the student’s right-hand keyboard is judged.

Then move to the left, arm exercise, preliminarily set the switch in block 3 to the corresponding position. On the display panel of block 8, the indicators “Figures and“ Leva, instructing the operator to work on the left side of the digital row of block 1 with the left hand, are highlighted.

When the Stop indicator lights up (after 50 presentations of M.H. symbols), they take readings from counters 20 and 21 and calculate the number of delayed decisions that judge the degree of development of the high-speed orientation skill on the digital row of the student's left hand keyboard.
