Description

The invention relates to engineering psychology, in particular to simulators, and can be used both to assess the professional suitability of operators and to evaluate them; functional state.

The purpose of the invention is to improve the accuracy of the assessment by the continuous analysis of the emotional state of the operator.

The drawing shows a functional diagram of a device for evaluating the psycho-physiological characteristics of the operators of automated control systems.

The device contains a unit for input of standards, an operator panel 2 containing shapers 3 and 4 of single pulses and a sensor unit of strength 5, element OR 6, unit 7 for monitoring the level of strength, frequency divider 8, unit 9 of registration, Schmidt trigger 10, key 11 , a logic probe 12, a counter of 13 cycles and a scoreboard 1A of the display of the degree of strength. The voltage level control unit 7 comprises an amplifier 15, an AND element 16, a generator 17 (time stamps), an integration unit 18, a threshold voltage setting unit 19, a voltage divider unit 20, a comparison unit 21, a register 22, an OR unit 23, block 24 elements I.

which depends on the functional state of the operator.

The device works as follows.

When the device is connected, the generator of the 25 clock pulses begins to produce pulses whose frequency is set using a capacitor C (100 pulses per second). These pulses are sent to the second input of the AND 26 element, but since there is no signal at the first input of the AND 26 element, the circuit is in the initial state of the Operator, the program of the main device 5, affects formers 3 or 4, feeding at In this case, the signal to the first input of the element 26 C of its output is fed to the decoder 30 of the switching unit 27, where a signal of duration is received from counter 28. After being converted in the decoder 30, the signal is fed alternately to logical chains of the display unit 31. In counter 32, incoming pulses are counted, which, after being converted into a code converter € 33, are displayed on counting indicators 34. The first counting indicator displays tens and the second one shows units of pulses per second.

the circuit is reset to the original co. In addition, the device additionally uses the third element but contains a generator of 25 clocks of 35 and 29; when data is input to the input, an AND 26 element, a switching element block from the output of a counter 28, containing a counter 28, a second And 29 element, and a decoder 30 and a block

signals corresponding to four logical units, at the output of the third element And 29, an indication sig31 appears, uniting sixteen logical chains, each of which includes a counter 32, a code converter 33 and a counting indicator 34.

 The studies are based on a method for evaluating a person at short intervals. With this method, the ability of a subjective time reference is determined, which, under the influence of arousal, leads to an underestimation of the time interval, i.e. its shortening, and with the development of the braking process due to the accumulation of fatigue, to an overestimation of the period of time, i.e. its lengthening. As a reference time, take the time the button is pressed by the operator, which is converted into a pulse, the duration

which depends on the functional state of the operator.

The device works as follows.

When the device is connected, the generator of 25 clock pulses begins to generate pulses whose frequency is set with the help of a capacitor C (100 pulses per second). These pulses arrive at the second input of the AND 26 element, but since there is no signal at the first input of the AND 26 element, the circuit is in the initial state. The operator, working according to the program of the main device, acts on the formers 3 or 4, supplying the signal to the first input of the element 26. From its output, the signal goes to the decoder 30 of the switching unit 27, where the duration signal from the counter 28 goes. In the decoder 30, the signal is fed alternately to the logical chains of the display unit 31. In the counter 32, the incoming pulses are counted, which, after being converted into a code converter € 33, are displayed on the counting indicators 34. The first counting indicator displays tens and the second shows units of pulses per second.

After filling the last counting indicator 34 with information

the circuit is reset to its original state using the third element 35 and 29; when the input of this element from the output of the counter 28

the signals corresponding to the four logical units, at the output of the third element And 29, a signal appears that goes to the control input of the counter 28 and sets the entire circuit to the initial state. The readings of the counting indicators 34 correspond to the times when the buttons are pressed by the operator. These readings are recorded and analyzed by the experimenter.
