The invention relates to automation and computer technology and can be used in training radio operators in listening and transmitting on a key.

The aim of the invention is to expand the didactic capabilities of the simulator due to the optimal choice of the initial speed of work.

Fig, 1 presents: 1ena structure of the simulator; Fig. 2 is a control block diagram; on fig.Z - diagram pulse shaper.

The simulator of the radio operator contains shaper 1 codes (automatic Morse code sensor, for example, ADKM-W), electro-acoustic converter 2 (headphones), counter (recording addresses), driver 4 (pulses of Dash), block 5

memory, counter 6 (read addresses), block 7 for inputting operator response actions, driver 8 (Dash pulses, adder 9 (modulo two), integrator 10, generator 11 (linear-linear voltage), indicator 12 (errors), block 13 control the pace of the workout, generator 14 (tunable discretely by the first inputs and smoothly, in the subrange, by the second input).

Block 13 contains a generator 15 (time intervals), connected to trip-ier 16, counter 17, decoder 18, shapers 19-22 single pulses, elements of the IPI 2326, elements And 27-32, RS-triggers 33-39.

Forms-gtel 4 and 8 contain sequentially connected integrator

40, generator 41, element 42 and counter 43,

The simulator works as follows.

The student listens to the signals coming 5 into the electroacoustic converter 2 (signs from the driver 1 codes) and with the same speed transmits them on the key of block 7. The speed of presentation of the signals of the signs gradually increases, which in turn causes the speed of the learner to increase transmission on the key. .

If a trainee makes an error during transmission, the increase in speed 15 slows down, and when the error rate reaches a set level, the indicator 12 lights up, instructing the learner to stop transferring to the key, focus, 20, and then proceed to work again after a certain period of time.

In addition, at the beginning of each workout, a choice of the optimal rate of presentation of characters is provided by one of the methods of the active search strategy. dichotomy method (half division method).

The essence of the method lies in the sequence of steps to find the desired value at a given interval by dividing the interval at each step of the K-n, half-lengths and selecting a half-segment containing the true value.

The choice of the optimal speed is provided by the operation of block 13, which controls the discrete reorganization of the generator 14.

In the first step, the generator 14 is tuned to the middle frequency of the range, and depending on the student’s correct work on the simulator, the unit 13 decides on restoring the generator 14 in the second step to the middle frequency of the half band lying either above the average frequency or below the average

frequency of the first pitch.50

The tuning of the generator 14 in the third step to the middle frequency of the same range is carried out in the same way as in the second step, only relative to the already selected middle jj frequency of the second step.

When the power is turned on, the block is reset.

5 memories, block 13,. counters 3 and 6.

The first signal, generated on one of the first steps of the control unit 13, triggers a generator 14, which generates a frequency of 0.5 f, where f is its maximum operating frequency, and controls the frequency of forming telegraph signs in the shaper 1 of codes,

From the driver 1 through the electroacoustic transducer 2 Tee graph signs begin to appear to the student. At the same time, these signs go to counter 3, where an address code is written to be written to memory block 5, in block 5, a logical zero corresponds to a Dot, a logical unit is Dash, Shaper 4 recognizes the elements of telegraph signs, the output pulse of which is allowed to write a logical units in memory block 5.

Received telegraph signs are trained and 1Y recognizes immediately. It transmits signs to the key of block 7, and informs the learners to the shaper 8 of the dash pulse and to the counter 6 of the read address. The control code generated at the outputs of counter 6, from block 5 of the memory, reads the elements of the characters written sequentially from the former I, t, e, reads the pulses corresponding to the Dash element, and goes to the adder 9 (two). the input of which receives impulses from the form-maker 8 (dash pulses) formed by the trainee on the key of block 7; If the learner reproduces the received signals without errors on the key of block 7, then there will be no pulses at the output of the adder 9, if it makes errors, then the outputs of the adder 9 appear to be pulses that go to the integrator 10, the output of which appears constant It is proportional to the frequency of errors. When the voltage at the output of the integrator 10 exceeds a certain threshold value, the indicator 12 lights up, the unit 13 turns off the generator 14, and the driver 1 stops. Introduce telegraph signs. The second signal generated at the outputs of block 13 re-generates generator 14 at a generation frequency of 0.75 f if the student at the first step of searching for the optimal frequency in his work made errors exceeding the set threshold or 0.25 f for purity if the student did not make errors . Similarly, the third signal generated on. the outputs of block 13 rebuilds generator 14 to a fixed frequency depending on the results of the student’s work in the second search step, and if, for example, in the second step the frequency of the generator 14 was 0.75f, then depending on the presence or absence of errors in the second step, the frequency of the generator 14 in the third step will be either 0.625 or 0.875f, respectively. At the end of the choice of the optimal initial frequency of operation, a signal from the second output of the block 13 starts the generator 11, which by its output voltage smoothly controls the frequency of the generator 14, its growth, the rate of rise is preset by selecting the parameters of the generator 11, If the learner makes mistakes in the course of the training, This voltage at the output of the integrator 10 arrives at the input of the generator 11, changes its parameters and changes the rate of increase of the voltage at the output of the generator, 11 thereby controlling the transmission rate of characters from you ode shaper 1, At pre-. The voltage at the output of integrator 0, during the training of a certain threshold value (the frequency of occurrence of errors has become unacceptably high), the indicator 12 Error lights up. In this case, the learner stops transmitting on the key and after the necessary interruption begins to train again. Block 13 works as follows. When the power is turned on, the generator 15 is started, the counter 17 is set to the initial position, and the triggers 16.33-39 (the installation circuits are not shown), the first pulse from the generator 15 output switches the trigger 16 to the state in which it is connected to the high potential appears at the input of the counter 17 and, accordingly, a high potential appears at the output of the decoder 18, which through the element 23 sets the trigger 16 to the initial state and enters the driver 20, the impulse from the output of the shaping machine 20 transfers the trigger 33 to the state This is where a high potential appears at its output, which is the output of block 13. This potential triggers the generator 14 with a frequency of 0.5f, .. If a potential (error in operation) appears at the input of block 13 sufficient to form a pulse of the former 19, this pulse through the OR 24 element switches the trigger 33 to the position at which a high potential appears at the output connected to the element And 28, The generator 14 is turned off. The second pulse from the output of the generator 15 switches the trigger 16 to a state where a high potential appears at its output connected to the input of the counter 17, and a high potential appears at the second output of the decoder 18, which through the element 23 sets the trigger 16 the source state and enters the input of the imaging unit 21. The impulse from the output of the imaging unit 21 enters through the open element 28 to the input of the trigger 35 and puts it in a state where a high potential appears at its output, which is the output of block 13,starts the generator 14 with a frequency of 0.25f. If there were no errors in the student’s work in the first operation interval (the first step of finding the optimal frequency), then the trigger 33 remains in a state where its high potential output is connected to the And 27, and Upon arrival of the pulse from the generator 21, the trigger 34 switches to the state in which a high potential appears at the output, which is the output of block 13, and starts the generator 14 at a frequency of 0.75 f, and also sets to its initial state through the OR 24 element trigger 33, the third pulse from the output of The potential generator 15 causes the appearance of a potential at the third output of the decoder 18, which, in turn, sets the trigger 16 to the initial state and causes the appearance of a pulse at the output of the driver 22, which through element 29 switches the trigger 36 from the initial state. The high potential at the output of the trigger 36 switches the trigger 34 through the element OR 25 and the initial state and starts the generator 14 at a frequency of 0.875-f, provided that there were no errors in operation in the first and second intervals (steps).

If in the second error interval in operation was trigger 34, the pulse from the output of driver 19 through element 25 causes the trigger 34 to its initial position, at which its high potential arrives at the input of element 30, and when the pulse arrives from driver 22, trigger 30 switches a state where a high potential appears at its output, which triggers generator 14 at a frequency of 0.625f.

If in the work of the learner the errors were only in the first step, then with the arrival of the pulse from the driver 22, the trigger 38 switches to the state where a high potential appears at its output, which sets the trigger 35 through the element 26 to its initial state and starts the generator 14 with a frequency of 0.375f.

If the errors were in the first and second steps, then the trigger 35 (with the appearance of errors — the pulse from the former 19 through the OR element 26) switches to the initial state, its high potential at the output opens the element 32, and with the arrival of the pulse from the former 22 the trigger 39 switches and a high potential at its output starts the generator 14 at a frequency of 0.125f.

The fourth pulse from the output of the generator 15 switches the trigger 16 to the state in which it is before the end of the exercise, the counter 17 captures the fourth pulse; At the fourth output of the decoder 18, which is the second output of block 13, the potential for starting the generator II is high.

At one of the outputs of the unit 13, a high potential is maintained, which ensures the operation of the generator 14 with the selected optimal initial frequency.

Shapers 4 and 8 work as follows.

The signal corresponding to the sign of the Morse code goes to the integrator 40, the output of which is a constant component. This voltage controls the pulse generation frequency of the generator 41, which thus turns out to be proportional to the transmission rate of the characters of the Morse code. The pulses from the generator 41 are fed to the first input of the And 42 element, the second input of which receives the pulses corresponding to the elements of the Morse code, The output of the And 42 connected by counter 43, where the number of pulses received from generator 41 over time is calculated, equal to the duration of the current element of the Morse code code. When counter 43 overflows, m appears at its output overflow sign indicating the presence of a dash in a Morse code mark. Counter 43 is reset with the falling edge of each Morse code element.

The use of the invention makes it possible to increase the efficiency of learning by implementing the choice of the initial speed of work according to one of the methods of the active search strategy - the dichotomy method (half-way, dividing), which allowed to get the optimal initial rate of presentation of signs taking into account individual personality characteristics in three search steps. the subject at the time of the training, reduce the time for preparatory operations in the simulator and thereby reduce the training time of the radio operator.
