Description

The invention relates to automation and computing, can be used in systems of automatized learning and sociological research.

The purpose of the invention is to ensure the accuracy of the device while expanding its functional capabilities by taking into account the influence of the functional states - jg of AI operators during group surveys in the answers to each question in a task.

The drawing shows a block diagram of a device for controlling the work of operators.

The device contains operator's consoles 1, counters 2 (the number of clicks of the answer button), dispenser 3 pulses, pulse shaper 4 (polling), adder 5 of the same name answers, block 6 for determining response time, block 7 for determining the average response rate of the operator , adder 8 results with the same name .25

The consoles 1 are designed to enter the answer to the current question of the task (questionnaire) and contain one answer input button 9 connected in series with counter 10 and digital indicator-30 with a torus 11, which displays the number of the answer entered from button 9.

Counters 2 contain the connected counter 12 and keys 13.

The adder 5 contains a successor-40 but connected elements RSH 19, the decoder 20 and the nodes 21 of the display.

Blocks 6 contain a series-connected element And 22 and a reversible counter 23, keys 24, the element dd OR 25.

Block 7 contains a series-connected element OR 26, a divider 27 with a variable division factor, a counter 28.CQ

 The adder 8 contains a serially connected decoder 29 and the nodes 30 of the display.

The device works as follows .55

The experimenter distributes tasks to the operators (questionnaires) and introduces them to the rules for answering questions and working with individual consoles. Questions

The tasks (questionnaires) may require answers on any scale, for example, on a ten point scale, or they may contain ready answers with appropriate sequence numbers. The operator must select the scale point or the number of the finished answer and fix it using the button 9 of his remote control 1 by pressing the appropriate number of times. On the digital indicator 11, he controls the number of the dialed answer. The answer with the help of the button 9 is allowed to be entered only when the number zero is displayed on the indicator 11. The experimenter, in accordance with the polling program, after a time sufficient to respond, presses a button in the imaging unit 4 and the device automatically reads, summarizes the same type of responses and displays them in digital form by the nodes .2 1.

In addition, the device records the motor reaction, i.e. the pressing time reads, sums up the same time intervals and displays them in digital form by the adder 8.

The same time intervals correspond to one, defined state of the operators. With the development of braking processes for the operators, the time interval will be lengthened, and under the influence of the excitation (for the operators), the time interval will be shortened.

At the end of the survey, the experimenter writes down the integral estimates for each answer in special tables. At the same time, on all consoles 1 in indicators 11, the numbers of the answers will be erased and when the zero is illuminated, consoles 1 are ready to enter the number of the next answer.

When the device is turned on, the generator 18 is started, and the counters 10, 12, 16, 28, the trigger 14, the counters 23 are reset (the installation circuits are not shown). The operator selects the answer number and by pressing the corresponding number of times of the button 9 on his console 1 generates the number of the selected answer. The pulses from the output of the button 9 are counted by the counter 10 and are displayed in decimal code on the indicator 11 for self-checking of the response set. In addition, the pulses from the output of the button 9 of the first remote control unit 11 are fed to the counter 12 of the first counter 2. Accordingly, from the second remote control unit 1, the pulses arrive to the second counter, etc.

After the experimenter has pressed the button in the driver 4, the trigger 14 is transferred to one state, the generator 15 is started, the first pulse from which goes to counter 16 and then the pulse goes to the second input of counter 10, sets it to zero, erases the answer number , prepares console 1 for entering the answer to the second question and opens the keys 13 of the first counter 2. Through the public keys 13, the response number code stored in counter 12 will go through the elements

the subtracting input of the reversible counter 23, and the input of the divider 27 through element 26. As the pulses enter the subtractive input of the counter 23, the code written in it will decrease. When the value of this code is reached in all bits of the counter 23, equal to zero, the keys 24 will close, the pulses from the generator 18 cease to flow into the counter 23. Simultaneously, the input of the divider 27 receives pulses, the number of which corresponds to the number recorded in the counter

23 (i.e., the total time for the operator to press button 9).

Using the divider 27, the operation of calculating the average is carried out;

19 and the decoder 20 already in the form of a unit; 20 Other inputs of the divider 27 are connected to

pulse and. is written to the corresponding node 21.

The second pulse from the output of the generator 15, similarly to that described, will provide the reading of the response code stored in the counter 16 recorded from the second console 1.

In this way, all of the consoles 1 are polled. Moreover, the same answers are summed up in the corresponding nodes 21, which allows determining how many operators selected this answer to the question posed.

In addition, the impulse from the button 9 of the first console 1 also enters the input of the element 22 of the first block 6 and permits the passage of pulses from the generator 18 to the summing input of the counter 23, where the pulse duration is recorded, i.e. time registration button 9

If the operator, answering the question of the questionnaire, presses button 9 several times (for example, if the answer number is five, he will press five times), then in the counter 23 of the first block 6 the total time of pressing button 9 will be recorded. Similarly, from the second console 1 the pulses go to the second block 6, and so on.

After pressing the imaging button 4, the polling pulse from the first output of the decoder 17 also goes to one input of keys 24 of the first block 6. The other inputs of keys 24 receive a code from a reversible counter 23, and if there is at least one unit in this code, the pulses from the generator 18 pass t through the keys 24 and the element 25 of the first block 6 on

outputs of the decoder 20, through which the divider 27 receives a control signal corresponding to the number of the operator’s response to the task question (an25 chambers), i.e. the number of pressing the button 9. The pulses from the output of divider 27, the number of which is already proportional to the average time of pressing the operator of button 9, go to counter 28, and then 30 to the decoder 29. At one of the outputs of the decoder 29, a pulse is written to one nodes 30 unit. Similarly, the survey of all reversible counters, chisels 23, is performed. The same values of the motor reaction of the operators are summed up in the corresponding nodes 30. The counter 28 is reset to the initial state by the falling edge of each signal.

40 la from the generator output 15.

After polling the last console 1, the trigger 14 is set to the zero state by a signal from the last output of the decoder 17. In addition,

g5, the same signal is used to reset the counters 12, 16 (installation circuits are not shown), and the survey on the first question ends. The device is prepared for further

50 work. The experimenter reads from the nodes 21 and 30 the results of the first survey and by pressing the button the former 4 proceeds to the next one. The use of the invention makes it possible to expand the functionality of the device during group polling by obtaining simultaneously at the same time the functional states of the operators for each question.

tasks (questionnaires), or throughout the task (the operator is not distracted by receiving these estimates) and allows for a comparative assessment of the methods for the psychological Psychology they cause when answering each question of the task.

Ultimately, this allows you to adjust the content of the tasks and obtain a higher efficiency of psychophysiological research using the polling method, improve the effectiveness of the group survey and weaken the influence of the functional state of the operator during the answers.
