The device for assessing the professional fitness of an operator contains a block 1 of information presentation, a shaper 2 binary codes, a shift register 3, a register 4 (memory), a block of 5 elements AND, a block 6 of comparison, a shaper 7 pulses (advancement of information), a distributor 8 pulses ( control), a block 9 of comparison (analysis), an operator console 10, a driver of 11 pulses (determining the search duration), a registration block 12, a trigger 13, an OR 14 element, and a delay element 15 via circuit connections.

Shaper 2 contains a pseudo-random sequence generator 16 (PSP) consisting of two four-bit generators, a generator of 17 clock pulses, an interdiction element 18 and an element OR 19,

Shaper 7 includes a generator

20series (of eight) pulses, elements

21 and 22 prohibitions, a short pulse shaper (with a delay) 23, delay elements 24-26, elements AND 27 and OR 28.

Distributor 8 includes a one-shot 29, a single (short) pulse shaper 30, trigger 31, AND 32 and delay element 33.

Block 9 includes a counter 34, the elements And 351-354 and the element OR 36.

The operator panel 10 has four buttons (formers of a single pulse) and an element OR 38.

Shaper 11 contains a generator 39 timestamps (with two outputs - low and high frequency), register 40, the elements And 41 and 42, the element OR 43 and the element 44 delay.

Block 12 includes a counter 35 of the number of timestamps, a counter of 46 correct answers and a banner 47 End.

The device works as follows.

Power up. The memory element is reset, the trigger 13 is in the single position (Fig. 9a),

A clock pulse (Fig. 9 b) from the output of the generator 17 through element 18 enters the input of the generator 16, causing the appearance of

it is in the binary eight-element sequence (Fig. 9c), which is applied to the information inputs of the register 3, and through block 5, to the control

the input of which is fed to the unit potential from the output of the trigger 13, to the information inputs of the register 4, to the inputs of the registers 3 and 4, having transferred the latter to parallel recording mode, and to the input of the shaping body 23. The delayed shortened pulse from the output of the imaging unit 23 (Fig. 9 g) ) enters the inputs of registers 3 and 4, ensuring parallel recording of a formalized binary number from the outputs of the generator 16

5 to register 3 (Fig. 9 d) and to register 4 (Fig. 9 e), to the input of block 6.

Since the applied code combinations from the outputs of the register 3 from the output of the register 4 are the same, when a pulse arrives

0 Interrogation (Fig. 9 g) to the control input of unit 6, at its output a pulse is received that will go to the counting input of the counter 34, ensuring the appearance at the first output of the last unit potential.

5 A delayed pulse from the output of element 24 (Fig. 9 g), element 21, to the control input of which zero potential is fed from the output of the last group of register 3, is fed to the input of generator 20,

0 by running the last one. A series of clock pulses from the output of the generator 20 (Fig. 9 h) is fed to the information input of the element 22, but will not go further, since a unit potential from the output of the trigger 13 is fed to its control input.

The delayed pulse from the output of the element 25 is fed to the input of the element 26 and through the element And 27, the input of which is the unit potential from the output of the trigger 13,

0 to the setup input of the register 3, returning it to the initial state. The delayed pulse from the output of the element 26 is fed to the P input of the trigger 13, having transferred the latter to the zero position (Fig. 9 a).

5 The appearance of the next clock pulse from the output of the generator 17 (Fig. 9 b) will ensure the formation at the output of the generator 16 of the next (new) binary combination (Fig. 9 c), which is recorded in

0 bits of the first group of register 3 (Fig, 9 E1). The same code combination from the output of the generator 16 is fed to the inputs of the group of block 5, but it will not go further, since zero is fed to the control input of block 5

5, the potential from the output of the trigger 13. The binary combination from the output of the first group of register 3 is fed to one input of block 6, to the other inputs of which the binary code combination of the check number is fed from the outputs of register 4 (Fig. 9e).

If the binary combinations are different, then when applying a pulse from the output of the imaging unit 23 (FIG. 9 g), there will be no signal at the output of block 6. Counter 34 remains as it was.

The delayed pulse from the output of the element 24 (Fig. 9 g) passes through the element 21 and starts the generator 20, a series of clock pulses from the output of which through the element 22, to the control input of which a zero potential is supplied from the output of the trigger 13 (Fig. 9 a), arrive at the clock input of register 3, moving the information from 1-8 to 9-16 bits, i.e. from the first group of exits to the second group of exits (Fig. 9 d2).

Writing to the first group followed by moving the binary combinations to the following groups of register 3 will be performed until the first (string) code combination is not available at the outputs of the bits of the last group of register 3. Since register 3 has ten groups of outputs, The tenth clock pulse from the generator 17 output will cause information at the outputs of the last (tenth) register group 3, which is fed to the inputs of the OR 14 unit. The unit potential from the output of the element 14 is fed to the input of the delay element 15.

After the comparison of the code combinations, the line combination formed by the eleventh clock pulse with the control combination, i.e. after issuing the result from the output of the block b to the counter 34, at the output of the element 15 there is a delayed unit potential (Fig. 9 and), which is applied to the control input of the element 21, blocking the trigger pulse from the output of the former 23 to the input of the generator 20. Des This binary string combination, formed with an 11 clock pulse and written into the bits of the first group of register 3, does not move.

At the same time, the unit output potential of element 25 goes through the element OR 19 to the control input of the element 18, stopping the flow of clock pulses from the generator 17, to the second input of the element 32 and to the input of the one-shot 29, launching the latter.

A single potential from the output of the single-vibrator 29, lasting for 1 s, goes to block 1 (to the input of the control indicator), highlighting the control number, and to the input of the imager 30.

The operator remembers the highlighted number (two digits - check mark),

After the control indicator has been canceled, the back front from the one-shot output

29 causes the appearance of a short pulse at the output of the imaging unit 30, which is fed to the input of the trigger 31, thus ensuring the appearance of a single potential at its output. The unit potential from the output of the trigger 31 goes to the first input of element I 32, the second input is fed to the unit potential from the output of element 15, and passes to the input of block 1 (the input of lower-case indicators), highlighting a line of two-digit numbers and to the input of element 41, ensuring passage timestamps from the first output of the generator 39 and their entry in the register 40.

The operator scans the line as soon as possible, determining the presence (absence) and number of check marks in it. At the end of the viewing, it immediately marks its result by pressing the corresponding button, the output of which, when pressed by 0, is a single pulse with a duration of 0.25 clock pulse. The pulse from the output of the element OR 38 is fed to the input of the trigger 31, cn in a single potential from the first output of the element And 32. Arrival

5 timestamps from the first output of the generator 39 and the register 40 is terminated, the indicators in block 1 go out,

If the operator correctly determined the presence of the control number (label), then pressing the button 37 impulses from its output through the corresponding element And 35 arrives at the input of the element OR 36. The impulse from the output of the element OR 36 will fix the correct answer in the counter 46 and go to the input ele 5 ment 42, ensuring the passage of clock pulses from the second output of generator 39 (with a frequency of hundreds of times greater than the frequency of following time marks) through the elements of AND 42 and OR 43 per clock

0 input counter 45.

If the operator has incorrectly determined the presence of a label, then when the button 37 is pressed, the pulse moves only at the output of the OR 38 element. This pulse will go to the input of element 33 and, through the OR 28 element, to the setup input of register 3, returning it to its original position. Delayed pulse (the delay time is longer than the time of information advance from the register output

0 40) from the output of the element 33 will go to the installation input of the register 40, returning it to its original position, and to the obnu ing input of the counter 34, returning it to its original state. The duration of incorrect answers in

5, the counter 45 is not fixed,

The control input of the element 18 is supplied with a zero potential from the output of the element 15, ensuring that the next clock pulse arrives at the input of the generator 16 and the control input of the register 3. Since register 4 is in the previous state (contains the control number information), its information inputs blocked by the zero potential from the output of the trigger 13, applied to the control input of the unit 5, the binary combination from the output of the generator 16 is fed only to the information inputs of the register 3, compared with the control information of the register 4, mark TIV presence or absence of matching by the block b, and advances hopping register 3 to output bits of the last group, i.e., the process is repeated.

After the tenth correct answer, a single potential appears at the output of the counter 46, which will block the output of the generator 17 and illuminate the transparency 47 End.

Based on the readings of the counter 45, the table scan time is determined (all rows with back1; mi responses) and the average row scan time or the average time of the comparison interval is calculated.

The use of the invention in devices for the psychophysiological studies of operators makes it possible to determine the comparison interval, which serves as a measure of the differential threshold when comparing test intervals of similar duration. The search time for a label — a random character (number) in a string — is found from the results of an error-free viewing of lines from beginning to end. The time for viewing the lines in which the operator made a mistake is excluded from the overall result,

According to the results of the search time (interval of comparisons), the operators are prepared for quick perception of symbols when reading test, cartographic materials and other information.
