The exclusion is related to automation and computing, in particular, to the quality control devices of the sperators, and is an improvement of the device for assessing the professional suitability of the operators of automated control systems according to aut. St. No. 936010.

The purpose of the invention is to improve the accuracy of the device with an increase in the efficiency of its operation by imparting to it functions that ensure the calculation of a guaranteed assessment of the quality of the operator’s work.

1a fi A block diagram of the device has been shown; figure 2 - diagram of the functional Converter.

The device (Fig. 1) contains adders 1 and 2, pulse formers 3 and A, quad 5, adder 6, control pulley distributor 7, switches 8 and 9, control pulse dispenser 10, switches 11-13, adjustable amplifier 14, functional converter 15, adders 16, block 17 setting the evaluation standard, indicator 18.

The functional converter (Fig. 2) contains converters 19-21 analog — a code, a switch 22, a data reference voltage 23, and an amplifier 24.

The device works as follows.

Preliminary, using block 17, the researcher sets the required value of the reliability value (WG) of the operator's quality assessment.

The discrete signal h. Characterizing the quality of the operator’s work (its temporal or exact characteristic and implementation) goes to the distributor 10 and through the normally open key I1 to the adder 1. From the output of the adder 1, because its input is shunted by the corresponding feedback element of the switch

The adder 6 receives a signal equal to the signal module h- at the output of the adder 1, because the circuit between them includes the formation circuit of the driver module 3. Adder 6 simultaneously produces the construction of one of the items in a square and the extraction of the root from the radicated expression.h.

The input signal received by the distributor 10 is registered 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 print of ovs is printed. computations after processing each peiilization.

At the same time, the value of the mathematical expectation and standard deviation parameters from the outputs of the keys 12 and 13 arrive at the entrance; converter 15, which also receives the voltage from block 17, is proportional to the required value of reliability (P) of the operator's quality assessment. The functional converter 15 generates a voltage proportional to the value of the guarantee factor k |., Corresponding to the required probability of evaluation and static indicators for evaluating the quality of the operator’s performance. The voltage developed by the converter 15 is fed to the regulating input of the amplifier 14, changing in direct proportion to its gain. At the output of amplifier 14, a voltage proportional to the product kpi is generated. which

the value of the guaranteed assessment of the quality of the operator's activities, which meet 11 the required probability value P. The value of the guaranteed rating in each measurement cycle is fixed by the indicator 18.

Functional Converter 15 operates as follows. Voltages proportional to the parameters h-, Pp, (i are fed to the corresponding converters 19, 20 and 21. The code values of these parameters from the outputs of the converters 19, 20 and 21 go to switch Z2, which switches the resistances in the feedback circuit of the amplifier 24, selected in such a way that, in accordance with the codes arriving from the converters 19, 20 and 21, the output of the amplifier 24 generates a voltage proportional to the value corresponding to the parameters h;, P, -, c, and the guarantee ratio.

By means of the sensor 23, an appropriate transformation scale is selected. I

Thus, this device allows to determine the guaranteed assessment of the quality of the operator's activity, which meets the required reliability value. In turn, the use of such an assessment eliminates incorrect judgments about the quality of its activity associated with the analysis of only the parameters of mathematical expectation and the standard deviation of the quantities characterizing the qualitative characteristics of the operator.
