Block 24 (FIG. 2) contains first, second, and third controlled sources of voltages 25-27.

Functional amplifier 20 (Fig. Contains adder 28, amplifier 29 and a diode approximator 30.

Pulse generator 9 (FIG. 4) contains a second (logarithmic) amplifier 31, a third adder 32, a matching node 33, a second adder 34, a first (logarithmic) amplifier 35, a first adder 36, a buffer register 37, element 38, input register 39 The device also contains a reset button 40.

The device works as follows.

The information in each training cycle is presented to the operator by block 2 by a command from block 1. The results of problem solving in each training cycle are entered by the operator through block 4, displayed on block 3 and recorded after passing through the elements

And 11, on the recorder 8. Element I1 is canceled by commands from block 10 and generator 9. From block 1, block 0, calculator 7 and imager 9 receive a signal equal to number N of the current learning cycle. If this number is less than four, then block 10 generates a signal that opens the elements And 11 and 12.

Thus, the results of solving problems in the first three training cycles are fixed in the registrar 8 and are fed to the calculator 7, which defines the statistical characteristics of the quality of problem solving by the operator in each training cycle and the speed NP of skills acquired by the trained operator. Then, through the value of N (1, the rate of change in the numbers of cycles of the learning process control cycles and the number of learning cycles, through which the quality of problem solving from the fourth to

specified by the researcher from the output of block 1. Signals corresponding to the CZoI Np probes come from calculator 7 to driver 9 after completing three training cycles. AT

The driver 9, during the operation of the operator in the next training cycle from block 1, receives a signal equal to the cycle number NJ. At the moment when the value of N reaches the value corresponding to the next number of the controlled cycle, which is calculated in the imaging unit 9., the latter generates a signal opening elements 11 and 12, resulting in a quality

solving tasks in a controlled cycle is recorded by the recorder 8, processed in the calculator 7 and fed through the element 12 to block 5.

In block 6–50, the final values of the X activities of the quality of problem solving and the parameters of the learning process are recorded.

The quality of the operator's work is determined by the probability P of the error-free execution of tasks, the type of which is determined by the composition of the tasks used to train the operator. B moment of stabilization of the parameters of training31

Neither the signal from the output of block 5 opens the elements of AND block 13, to the other inputs of which the code value is received in the inertiality of the error-free execution of the task, measured in the last training control cycle. The probability code value is written to register 14 and stored there throughout the entire training phase of the operator. At the output of the converter 15, a voltage is formed that is proportional to the probability value of the error-free execution of the tasks by the operator at the time of stabilization. At the output of the logarithmic amplifier 16, this voltage is converted to a voltage proportional to the value of 0.5 1 p and then goes to the inputs of the adder 19 and the amplifier 17. The gain of the amplifier 17 is adjusted to twice the relative time value by adjusting the voltage at the output of source 25 operator control costs. The gain of amplifier 18 varies inversely with the voltage at the output of amplifier 17. The input of amplifier 18 from source 26 receives a voltage proportional to the number Nf of tasks assigned to be executed by the operator in this training cycle, multiplied by 4. Thus, at the output of amplifier 18, voltage is proportional to 4 N 1-lnp

functional amplifier 20 is a voltage proportional to

To form a voltage proportional to one, the input of the amplifier 20 receives the unit voltage from source 27. At the same time, the same voltage goes to the input of the adder 19, at the output of which a voltage is formed that is proportional to the rational value of period K control. This voltage is converted into digital form in converter 21. The code value of the monitoring period in the mode of stabilization of training parameters is fed to the control inputs of the switch 22. Under the influence of the control signals, the switch 22 realizes that the feedbacks of the counter 23 are switched in such a way that ko108764

the division factor of counter 23 would correspond to the calculated value of the monitoring period. From this moment, pulses are removed from the output of the counter 23, the period of which corresponds to the period of the operator's quality control. Under the influence of pulses, e.pementa II and 12 are opened. Then the work proceeds as described above. In the event that the operator, having changed the structure of the assignment, moved back to the training site, block 5 stops generating a signal about the end of the learning process. On this signal, the researcher, by pressing the button 40, zeroed the register 14, and the device goes into the learning mode. In this case, the monitoring period is determined by shaper 9.

The functional amplifier 20 (FIG. 3) operates as follows.

The adder 28 generates a voltage proportional to the difference

which is then fed to the input of the amplifier 29. Diode approximator 30 provides a voltage that is proportional to the value of the function fx, and is an assembly of diode limiters approximating the function Yx. So the output

The imaging unit 9 (Fig. 4), when determining the moment of the next control at the operator’s training stage, operates 40 as follows.

The formatter 9 starts with the fourth training cycle. The input register 39 receives the signal, N45, from block 1. The adders 36 and 32 receive the signal equal to from the calculator 7. The register 37 stores the value Nj ,,. the numbers of the last training cycle in which it produces 50 s control. The signal comes from register 37 to the input of the adder 36. From register 39 to the input of the adder 32, a signal is received that is equal to IG. At the outputs of the adders 36 and 32, 55 signals are generated equal to the difference between the values arriving at their inputs. These signals are amplified by amplifiers 35 and 31. After amplifier 35, the signal is fed to one input of the adder 34, to another

the input of which receives signalj equal to l / Njjp, from calculator 7. The constant signal, paBfibM InCNnj ,, - Ы ,,.) - - is fed to one input of node 33, to the other input of which comes a variable signal equal to ln (N p-Nf). In case of equality of the signals received from the adder 34 and the amplifier 31, the node 33 generates a signal that opens the elements P, 12, 14. In this case, the contents of register 39 are rewritten into register 37.

The optimality of the control process in the proposed device is achieved by conducting a selective control, which takes into account the specifics of the operator's training process, the level of his professional costs and skills to conduct control. This significantly reduces the required amount of recorded parameters and the time for their processing and analysis in the device.
