(54) DEVICE FOR ASSESSMENT OF PSYCHOPHYSIOLOGICAL CHARACTERISTICS OF OPERATORS OF AUTOMATED CONTROL SYSTEMS

12

The invention relates to automation and computing, and is intended to evaluate the characteristics of decision-making operators when monitoring digital information.

A device is known comprising an information input unit, a count of the number of presentations, a control unit, a random signal generator, a switch and a frequency error meter P.

Such a device does not reflect the specifics of the operator when monitoring digital information.

Closest to the present invention is a device comprising a display of information, an operator console, a memory unit, a comparison circuit, a random number generator, an error counter, a time counter, a program block, an adder, an information correction block, an information quality assessment unit, a selection block bits and the switch, the first output of which is connected to the memory unit, and the rest are connected to the inputs of the information display panel and the information inputs of the information correction unit, the control input of which is connected to operator's pulse, and the output - with the scheme

comparison, the first input of the switch is connected to the output of the random number generator, and the second to the output of the bit selection unit, the first input of which is connected to one of the control outputs of the program block, and the second through the adder is connected to the output of the quality evaluation unit of the field unit. information entry, first entry

10 of which is connected to the output of the error counter, and the second to the information output of the program block C2.

However, this device does not allow to evaluate the characteristics of the operator in making decisions when monitoring multi-parametric digital information, which reduces the functionality of the device.

The purpose of the invention is to improve the accuracy of the device.

The goal is achieved by the fact that the device for assessing the psycho-physiological characteristics of the operators of automated systems

25, comprising a sequentially connected operator response input unit, a comparison unit, a time counter, an evaluation program setting unit, and a random code sequence generator, and

also a serially connected switchboard and information board, serially included code generator and an element of AND-OR, as well as three switches, the second output of the evaluation task setting block through the first switch connected to the first input of the switch, the second input of which is connected via the second switch to the output of the random code generator and to the third output of the task program for the evaluation program, the fourth output of which is connected via the third switch to the third input m of the switch and the first input of the code generator, the second input of which is connected to the first output of the evaluation task setting block, and the output to the second; the input of the information board, the second input of the AND-OR element is connected to the output of the switch, and the output is connected to the second input of the comparison unit.

Fig, 1 shows a functional diagram of the device; Fig 2 is the same shaper codes; FIG. 3 is the same; the block of AND-OR elements in FIG. 4 is a timing diagram of the control algorithm.

The device contains an information board 1 consisting of a digital information indicator 2 and alphanumeric indicators 3 logical conditions, a switch 4, a generator 5 of a random sequence of codes, a switch 6, a switch 7, a block of 8 AND-OR elements, a switch 9, a program setting block 10, shaper 11 codes, operator response input unit 12, comparison unit 13, time counter 14.

The code generator 11 comprises successively connected random number sensor 17, a decoder 18, a switch 16 and a switch control node 15.

The functional block diagram of the 8 AND-OR elements contains the logical elements AND 19 by the number of information signals connected in series with the OR element 20.

Block 10 is made on the relay contact elements and implements the control algorithm.

Switch 7 (the number of information signals) is designed to connect the K of the n digital indicators 2 information.

Switch 9 (dimensionality of information signals) is designed to connect .k from m digital information indicators of the scoreboard 1,

The former 11 is designed to develop a set of logical conditions (7;, max, min) necessary to make a decision.

the operator of the generated myogoparametric digital information

To this end, on command from block 10, sensor 17 generates random numbers, each of which corresponds to one of the possible logical conditions. Depending on the dimension of the information signals specified by the switch 9, the switch 16, at the command of the node 15, distributes the signals of random logical conditions generated by the sensor 17 and the decoder 18 to the corresponding indicators 3

The device works as follows.

in a way.

According to the signal from the first output of block 10, generator 5 generates random numbers that define the digital information in each of. At the bits specified by switch 7, on command from block 10, switch 9 generates a signal to the control input of switch 6 for distributing the generated n-bit digital information to the corresponding digital indicators 2 of board 1 (dimensions mxn),

Simultaneously with the imaging unit 11, a logical conditions code is issued for the corresponding indicators 3.

Thus, the generated multi-parameter digital information during the time period specified by the switch 4 is presented to the operator.

The operator monitors the status of the indicators of the scoreboard 1 and selects a set of information signals that meet the criteria specified by the indicators 3. The decisions are entered by the operator through the keyboard of the responses of block 12,

The evaluation of the temporal characteristics of the operator’s activity upon decision making is carried out by the counter 14 from the moment of presenting the information until the moment he entered the right decision.

With the help of block 8 and block 13, the control of decision making is carried out,

In the case of the operator making the wrong decisions, the information on the scoreboard 1 is not reset, which serves as a signal for a second decision.

The signal corresponding to the time of making the correct decision from the output of the counter. 14 is fed to the input of the unit 10 for its registration and is a command to change the dimension m or the number n of information signals.

Thus, the proposed device makes it possible to evaluate the characteristics of an operator in making decisions, while monitoring multi-parametric digital information, which significantly expands its functional capabilities.

The proposed device for evaluating the characteristics of decision-making operators differs from similar previously known ones, as it reflects the peculiarities of the operator's work in controlling multiparameter digital information and thereby increases the efficiency of training and professional selection of operators, as well as reduces the time and cost of preparing them on 10%,
