The drawing shows the pro raei ": e device ..

The device for evaluating the professional suitability of operators of automated control systems contains a block 1 of generators, a block 2 of presentation of training information, a block 3 specifying the number of stimuli, a switch 4, a block 5 specifying the exposure time, a key b, a trigger 7, an operator console 8 and a block 9 registration. The generator unit 1 contains a generator of 10 single pulses and a generator of 11 clock pulses of a unit 2 of presentation of training information — a generator 12 of a random sequence of codes, an AND 13 element, an adder 14 modulo two, an annular shift register 15 and an AND 16 element of a number 3 task stimuli pulse counter 17, multi-position switch 18 and inverter 19. Switch 4 consists of multi-position switches 20. Bloch 5 sets the exposure time contains multivibrator 21, key 22 power supply 23 23 operator’s console 8 - one nadtsatikontaktnye 24 locations stimuli latch connected to indicators 25, button 26 of the digital number of the registration unit 9 - a first group of AND gates 27, inverter 28, multi-input OR gate 29, a second group of AND gates 30, a group of counters 31 errors.

In accordance with the program of experiments, the experimenter determines the number of stimuli of digits of a numerical series affecting the subject and the time of their exposure. The subject visually fixes the information presented to him and, at the end of the exposure time, compares the stored information with the reproduced information. The maximum number of stimuli memorized by the subjects / determines the volume of his short-term memory and the state of the visual function of attention, and the nature of the mistakes made is his ability to train a short-term memory.

The device works as follows.

After turning on the power, the experimenter presses the Set O button (not shown in the drawing), starting this generator 1 in block 1, the signal from the third output of which goes to the corresponding inputs of the register 15, the counter 17 of the group of counters 31 and the second zero input of the trigger 7, and sets them to zero state. Then, with noMOHibra switch 18 of block 3, the experimenter (h sets the number of stimuli presented to the subject. For example, if the number of stimuli is six, then switch 18 is set to the position at which the sixth trigger of counter 17, which is a shift register, is connected with the input of the inverter 19. After that, the examiner uses the Record button (not shown) to connect the generator 11 to the clock inputs of the driver 12 and through the element 16, to the second input of which the unit from the inverter 1 arrives 9, to the second input of the register 15.

The pulses from the former 12 are an element And 13, on the second input of which

a unit arrives from the If inverter, and the adder 14 is fed simultaneously to the first input of the register 15, filled in randomly, and to the second input of the counter 17, s of which the number of received units is counted. As soon as their number reaches the value set by the experimenter using switch 18, the output of the corresponding trigger in our example from the sixth counter 17 through the switch 18 to the input of the inverter 19 receives a signal that removes a single potential from the second inputs of the And 13 and 16 off elements driver 12 from the input of the register 15, and stops the supply of clock pulses.

The correct counting of pulses recorded in register 15 is ensured by the fact that the output of the last trigger in register 15 is connected to the second input of cyNMaTopa 14 connected to the record input (information register 15. The units recorded in register 15 are fed from the outputs of its triggers to switches 20 of switch 4 .

I.:.

When the test subject is ready, the expimenter presses the Exposure button (not shown), thereby providing a signal from the generator 10 from the second output of block 1 to the single input of trigger 7 and to the input of multivibrator 21 of block 5. The trigger 7 is set to single. Multivibrator 21 produces a single pulse, the duration of which is equal to the exposure time and is determined by the parameters of the multivibrator circuit, which are set by the experimenter in advance. Impulse output; the multivibrator 21, entering the control input of the key 22, closes it, and from the output of the source 23 through the closed key 22 to the second inputs of the indicators 25 enters the igniting voltage. At the same time, the display (only those indicators and digits to which the control signals from the register 15 were received are shown).

The test operator visually captures both the numbers and the placement of the indicators on which these numbers are highlighted. Then, on the remote control 8, it produces the memorized information by pressing the button 24 of the illuminated indicator and the button of the digital p. 26, corresponding to the highlighted figure on the indicator 25. Pressing the button 24 switches the ten outputs of the switch 20 from the indicator 25 to the elements 27 of block 9 At the same time, by the eleventh. Pin of the button 24, the output of the trigger 7 is connected to the third input of the And 30 element. If at least one stimulus is displayed in the indicator 25, then the input to one of the And 27 elements enters. If the subject correctly reproduced the stimulus with the help of the corresponding button 26, then from the output of trigger 7, through the contact of button 26 and the element OR 29, the unit enters the second inputs of the elements and 30 and simultaneously through. And 27 - To the input of the inverter 28. Null potential from the output of the inverter 28 n6adutsz to the first inputs of the elements And 3p. Consequently, the output of the elements And 30 signal will not. If the stimulus or indicator to which the stimulus illuminates, the subject indicated incorrectly, then the first inputs of the And 30 elements receive 1 distance, since the zero potential removed from the outputs of the And 27 elements will be inverted by the inverter 28, Therefore, all three inputs of the And 30 element , sootvetstvuvalypolodimomu indicator 25, received unit potentials, and from its output unit; is recorded in counter 31, indicating an error on this indicator. After responding to the subjects for all indicators and stimuli presented in this cycle, the experimenter turns on the key 6 Errors and indicates to the subject the mistakes made, and those indicators light up which the subject identified incorrectly but incorrectly determined the stimulus or ng1 presses the Record button and forms a new algorithm in according to the program of tests. sets a different number of incentives. The operation of all units and elements of the device is carried out similarly as described in this case, the information available in the counters 31 is not charged. After completion of the tests, or in the process of testing, if there is a need to specify the test: 5 to be remembered (to be trained; to make mistakes. For individual training, the experimenter will press key 6 of the error, thereby connecting the output of trigger 7 to the second INPUT of block 5 to control the input of the key 22. Under the action of a single potential from the output of the trigger 7, the key 22 closes and through it from the output of the source 23, the ignition voltage enters the second inputs of the indicators 25. Information about the number of errors recorded in the counters 31, p is given from their outputs to the first informational inputs of indicators 25. Thus, each indicator separately highlights the number of errors that were made when working with this indicator.After the tests, the experimenter analyzed the received results for the specified program, i.e. of the digital material on the magnitude of the set of numbers and the nature of the errors, while doing this, it concludes that the subject is suitable for working with control panels of automated systems. I -. . ;. . The use of the invention in devices for professional selection and simulators makes it possible to more accurately assess the professional suitability of operators of automated control systems by taking into account and analyzing the errors made by them / increasing the efficiency of individual training of short-term memory due to the display of errors after each response to the presented experiments. -sator stimuli, which makes it possible to take into account and develop the individual abilities of the subjects to build up, the volume of the short time and to long-term memory, reduce the time and cost of training operators at the expense of organizations of groups of students with approximately the same abilities, allows us to apply the same type of student methodology.
