The invention relates to automation and computing, in part with the operator's quality control devices, and can be used to control the quality of training or training of operators of various profiles and is an improvement of the invention according to the author. No. 936010.

The purpose of the invention is to expand the didactic capabilities of the device with an increase in the efficiency of its work by imparting to it functions that provide a rapid assessment of the accuracy of the obtained statistical estimates.

The drawing shows a structural diagram of the proposed device.

The device contains adders 1 and 2, shapers 3 and 4 pulses, quad 5, adder 6, distributor 7 control pulses, switches 8 and 9, distributor 10 control pulses, keys 11-13, switch 14, summator 15, adjustable amplifiers 16 and 17, switch 18, adder 19, comparator 20, shapers 21 and 22 reference voltages, indicator 23.

The device works as follows.

A discrete signal characterizing the quality of the operator’s performance (its temporal or accuracy characteristic in the implementation) goes to the distributor 10 and through the normally open key 11 to the adder 1.

The input signal received by the distributor 10 is registered therein and goes to the distributor 7, which switches the feedback elements of the switches 8 and 9, adders 1 and 2, and also feeds the keys 12 and 13, through which the results of the calculation are printed processing each implementation. The signal (h;), equal to the mathematically-matched DI2 of the input signal after the j -th implementation, is fed to the input of the adder 15, at the output of which a signal is formed that is proportional to the product b | - | W. The multiplication of the signal hi by a factor equal to -. , is produced by connecting in the feedback circuit of the adder 15, the corresponding feedback element of the input field of the switch 14 via signals from an additional distributor 7. The signal from the output of the adder 15 is then used as a control signal to change the gain of the amplifier 17. Reference voltage living with

Shaper 22 is fed to adder 19, at the output of which a signal is generated - corresponding to the table values of t - Student's t-distribution with (j-lj degrees of freedom at a significance level of. Formation of these signals is performed by switching switch B elements in the feedback of the adder 19 from the signals from the first output of the distributor 7. The signals from the output of the adder 19 are used as controls in an adjustable amplifier (.6, to the information input of which 55 and 13, corresponding to the value (f,) srednekvadraticheskogp otklonepi estimation de teli.HOC i tf f,) iiep.-rrop; i and -i

The signal at the output of the driver 21 is amplified in advance and determines the required accuracy of estimating the value of h; considered admissible if the inequality holds. {.

where P is the required accuracy of the estimate.

When this inequality is fulfilled, the comparator 20 generates a control pulse on the indicator 23, with which the signaling of the end of the research of the operator’s activity is carried out.

Thus, the proposed device allows an assessment of the statistical characteristics of the quality of operator activity, using statistically optimal sample sizes, taking into account the required accuracy of this assessment, as well as reducing the costs of engineering and psychological tests, training and training of operators associated with non-optimal choice of scope of testing. With

This increases the accuracy of the statistical estimates obtained.
