Block 2 contains the elements AND 33, the elements OR 35 and 34, the element 36 prohibition, the inverter 37 and the diodes 38 (separation elements).

The simulator works as follows.

The power is turned on, the button 8 is pressed, the distributor 9 is set and the counters 2, 29 and 30 are reset, and the trigger 18 is in the zero position. The simulator is ready to go.

The student presses the button 7. Imp. from its output through the element 31, enters the information input of the element 17 and passes to the input of the distributor 9, since the prohibitive input of the element 17 is supplied with the current potential from the output of the trigger 18, being “one unit for the first time”. Single note ; ia, 1 from the first output of the distributor 9 enters the second input of the board 23, highlighting the left half of the keyboard and the axis; UVS, relative to which the learner ;; it is necessary to determine the symmetric letter to the input of igtera 18, by transferring it to a single position, and to one) the input of the element I 20, to another input of which the button 7,

counter 21. A signal (unit potential) from the output of counter 21, acting on the input of the diffuser 22, causes the appearance of a single potential at its output, which is 2 steps on one of the inputs of the board 23, highlighting a symbol (letter) on it, and from the inputs of block 2, corresponding to the letter, symmetrical highlighted on the scoreboard 23.

Trainee on the highlighted letter on the scoreboard 23 mentally searches for symmetrical

An impulse from the output of the unit 2 will go to the input of the counter 30 and fix the answer. A single potential from the output of the element 33 through element 34 will arrive at the input of the driver 37, ensuring the appearance at its output of a zero potential that is applied to the inhibitory input of element 36, ensuring the passage of a pulse to the output of unit 2.

The impulse from the output of block 2 will go to the input of counter 29, fixing the correct answer, and through element 31 to the inputs of elements 20. Since a single potential is applied to the input of element 20, then a pulse from its output goes: input to counter 21, will change Ci o state and will ensure the appearance of 22 unit capacities at the second output of the depotfrator. A single notencia.p from the second output of the diverter 22 will go to another of the inputs of the scoreboard 23., providing a flashing to the letters from the first, and then to one from the inputs of block 2, corresponding to the letter symmetrical highlighted on the scoreboard 23.

The student determines the location of the letter, the kenya of the letter, the symmetry of the highlighted. :. iospro- 5 tantalizes her.

If the learner is; eprilpo determined (reproduced). The placement of the symmetric letter (symbol), then} ia output b; 1ok 2

Wits pulse, which will go to the input of the counter 30 and record the next answer.

On the scoreboard 23 the same letter continues to shine. It will go out if the student correctly reproduces the symmetric letter.

If the student in the first cycle correctly reproduces all symmetrical letters about the axis of the CRS, then with the correct answer to the last K-th (K, 5) letter at the output of the counter (K + 1, the last) 21, the pulse (overflow) through the element 16 will go to element 19, the student will be warned by a short phonetic signal about the first cycle of the program and the need to take readings from meters 29 and 30, and to the input of the distributor 9, transfer the unit from the first output to the second output, thereby making the transition to the second cycle.

The unit potential from the second output of the distributor 9 enters the input of the board 24, highlighting the right half of the keyboard and the axis of the SLR, relative to which the learner must determine symmetric letters, and through element 20, to another input of which impulse comes from block 5, to the input of the counter 21 The signal from the output of counter 2, acting on the input of the decoder 22 will cause the appearance of a unit potential at its output, which will go to one of the inputs of the board 24, highlighting a letter on it and to one of the inputs of block 2, corresponding to a letter symmetrical to light hydrochloric the score is 24.

The actions of learning and the work of the blocks, nodes and elements of the simulator in subsequent cycles are similar to that described.

In the third cycle, the student identifies symmetric letters about the centrally symmetric point B for the left half of the keyboard, in the fourth cycle - relative to the point L for the right half of the keyboard, in the fifth cycle - about the axis of the middle row of the entire keyboard, in the sixth cycle - relative to the axis separating the right and left sides of the keyboard. After each cycle, the student takes readings from counters 29 and 30.

With the correct answer to the last nth symmetric letter in the sixth cycle, at the output of counter 21 there is a pulse that goes to indicator 31, illuminating the banner “End and notifying the learner about the end of the training, and to the input of trigger 18, moving it to the zero position . The simulator is ready for re-training.

At the end of the training session, the trainee gives the results of the training, taken from counters 29 and 30, to the teacher for analysis.

The use of the present invention in the preparation of telegraph operators extends the didactic capabilities of simulators.

since the basis of knowledge of the structure of the object (the keyboard of the telegraph apparatus) is based on the principle of symmetrical transformations, which allow to establish the main

properties of the object under study that remain invariant with respect to the transformations carried out. When mastering the keyboard of the telegraph apparatus, such an invariant is the distance between the given and the required keys relative to

 specific axis or point. Relying on it, it is easy enough for the trainees to work out a holistic view of the mutual arrangement of the keys and the entire structure of the construction of the telegraph keyboard.

5 apparatus.

The form: the whole of the holistic alpha-simple HCTBeiiHoro idea of the entire field of the keyboard is accomplished: 1 by performing a set of exercises to find the character 0 -la (letters) that are symmetrical with respect to the left axis and the left and right axis and the right point L the keyboard half, the middle axis 1 of its row and the pox separating the right and left parts for the entire keyboard. Practicing such exercises, which require a sufficiently intense mental activity, makes it possible to firmly grasp the mutual arrangement of symbols on the keyboard of the telegraph apparatus, to reduce the time it takes to move.

The Q move from one key of the keyboard to another without visual control does not require the mandatory return of the fingers to the initial position and ensures high accuracy of operation.
