Description

The invention relates to simulators and can be used for the professional selection of operators, as well as for assessing their level of preparedness.

A simulator is known, a comparison block, connected to the response panel and an error counter, a control block, a random event sensor, switches, memory blocks and a clock generator, as well as a second counter and an And 1 element.

The disadvantage of the simulator is the low efficiency of training a short-term memory.

The closest to the invention is a transponder containing an operator's console, the first and second inputs of which are connected respectively to the first and second inputs of the comparison unit, the third and fourth inputs of which are connected respectively to the first and second outputs of the input module, and the output to the first input of the unit registration, the second input of which is connected to the output of the key, the first input of which is connected to the first output of the unit for inputting the standards, and the second - to the first output of the Schmitt trigger, the second output of which is connected to the input of the unit vb standards and, as input through an OR - to the outputs of the remote operator, the output of OR element are also connected through divider pulses to the third input of the recording unit 2.

A disadvantage of the known simulator is the low efficiency of studies of the preparedness of the operator, since it is impossible to establish a relationship between the rate of activity and the operating level of the operator's functional system.

The purpose of the invention is to increase the accuracy of the device with an increase in the efficiency of studies of the preparedness of the operator by creating conditions for the forced rate of activity (a time is set for the response

20 for each stimulus that may vary within certain limits ;.

This goal is achieved by the fact that the simulator containing the sequentially switched on operator’s console

25 and the first OR element, the second OR element connected in series, the 1st 1tta trigger, the standard input block, the comparison block and the registration block, the second input of which is through the divider

30 frequency connected to the output of the second

of the OR element, and the toothy input — via the first key to the second output of the Schmitt trigger and to one of the outputs — the input unit of the standards, the sequentially connected rhythm setting unit and two AND elements, the second inputs of which are connected to the corresponding operator console outputs, and the outputs — with the second input of the power unit and the input of the second element OR, the output of which is connected to the first input of the task setting unit, the first and second outputs of which are connected to the fourth and fifth inputs of the registration unit, respectively, the second input unit and set the work rhythm connected to the output of the first element OR.

In this case, the rhythm task setting unit contains serially connected clock pulses, delay elements, a second key and a third element OR, as well as a single vibrator and a third key, the first and second inputs of which are the first and second inputs of the block, respectively. the output is connected to the second input of the third OR element, the output of which is the second output of the block, the output of the clock generator is the first output of the block, the one-shot input is the first input of the block, and the output is connected to the second input of the second key.

The drawing shows a structural diagram of a simulator of an operator of automated control systems.

The simulator contains an operator panel 1, unit 2 input standards, unit 3 comparison, unit 4 setting the work rhythm, trigger 5-Schmitt, first key b, first element AND 7, second element AND 8, first element OR 9, second element OR 10, frequency divider 11 and registration block 12.

Remote controller. 1, the operator contains a driver of 13 single zeros of the zeros and a driver of 14 single pulse units (the control buttons of the drivers are not shown.

The standard input block 2 contains an annular shift register 15, a generator of 16 single pulses (control button is not shown),. two-way switch 17, key switch 18 and multi-position switch 19.

The unit 4 for setting the work rhythm contains a clock generator 20. clock pulses, a delay element 21, a second key 22, a third key 23, a one-shot 24 and an element OR 25.

The registration unit 12 has a decision indicator 26, an error counter 27, a cycle counter 28, a count of 29 rhythm disturbances and an indication node 30.

The simulator works as follows.

After switching on the simulator, the experimenter. Using the multi-position switch 19 sets

the length of the stimulus presentation algorithm. For example, if each cycle of the algorithm contains three members, then using switch 19, the output of the third trigger of the ring shift register 15 is connected to the D input of the first trigger. Then the switch 17 is set to the position and setting O by plugging in the R-inputs of all the triggers of the register 15

to the generator 16 single pulses, and the Setup button (not shown) is pressed. The signal from the output of the generator 16 erases all the information from the ring shifting

register 15. After this, switch 17 is moved to position I of Algirithm and the switch 18.J (i (-, and)) dials the algorithm using the keys of the switch. For example, if the algorithm

has the form 101, then the keys, 18 and 18, are turned on, and the key 182. remains in the off state. The Setup button is pressed again, and the selected stimulus presentation algorithm is written to the ring shift register 15. The state of the switch keys 18 does not see the subject.

Then, in accordance with the test program, the experimenter establishes the duty cycle of the generator of 20 clock pulses and allows work with the trainer to the subject.

The signals from the generator output of 20 clock pulses arrive at the first inputs of the And 7 and 8 elements, the delay element 21 whose delay time is equal to the duration of the pulse, and the decision indicator 26. The duration of the luminescence of the indicagore 26, which signals the subject of the need to press a button, is equal to the duration of the clock pulse of the generator 20.

If the subject maintains the rhythm of making decisions, the experiment

mentator, then when you press the buttons Zero or One (not shown), the pulses from the generator 13 or 14 single pulses of zeros or ones through the elements And 7 or

8, the first inputs of which receive a signal from a generator of 20 clock pulses, go to block 3 of the comparison and to the element OR 9, and through the element OR 10 to the key 23 ,.

Suppose that the subject .. pressed the Zero button. In this case, the imaging unit 13 generates a single pulse, which is supplied through the element AND 7 to the input of the comparison unit 3 and

| through the element OR 9 to the input of the trigger

5 Schmitt, the divider 11 (the division factor of which is equal to the length of the algorithm and is set by the experimenter in advance), the one-shot 24 and the control key input 23, opened it, therefore the pulse from the output of the element OR 10 does not go to the meter

29 rhythm disturbances.

Since at the moment of pressing the button from the direct output of the first trigger of the ring shift register 15 In accordance with the algorithm entered by the experimenter, unit 3 is removed in block 3, the output signal records the unit to the error counter 27. The output of the annular shift register 15 is also connected to the input of the switch b, the control input of which receives a signal from the output of Schmitt trigger 5. At the time of downgrading of this signal, the key b connects the output of the ring shift register 15 to the display 30 Wells, the indicator (not shown) of which shows the output status. The return of the Schmitt trigger 5 IB the initial state disconnects the node

30indications from the ring shift register 15, and the signal from its inverse output, arriving at the C input of the ring shift register 15, shifts its contents to the right by

One bit. Now in the ring. shift register will be recorded information type 110.

At the same time, a pulse from the output of the element OR 9 triggers a one-shot 24, which outputs a pulse to the control input of the key 22, and opens it. The duration of the pulse produced by the single vibrator 24 is 2 times longer than the duration of the pulses produced by the clock generator 20, so the pulses from the generator 20 arriving at the input of the key 22 through the cell 21 (delay value equal to the duration of the clock pulses) do not pass to the counter 29 rhythm disturbances.

Next, the subject again presses, at his discretion, one of the buttons Zero or Unit in time to allow the signals of the indicator 26 of the decision principles. The work of all the blocks and elements of the simulator at the same time carried out similarly to that described.

In the event that the subject pressed the button before the permit signal was received or after the permit signal had already passed, the signal from the output of one of the drivers 13 or IL 14 through the element OR 10, the closed key 23 (since there is no signal on the control key 23); and the element OR 25 records a unit in the counter 29 rhythm disturbances. If test1 & 1st missed the enabling signal, then the pulse from the generator 20 clock pulses, delayed on the delay element 21, through the closed key 22 (no trigger pulse goes to the single vibration 24) and the element OR 2 also writes one into the counter 29 rhythm disturbances.

Comparing the subsequent members of the algorithm, the subject achieves their complete match. The number of cycles presented to the subject of the algorithms is recorded by a counter of 28 cycles.

The experimenter, analyzing the information from counters 27 - 29, determines the characteristics of the subject. Then, in accordance with the test program, the experimenter proceeds to study the new algorithm for presenting stimuli, gradually complicating it and reducing the duty cycle of the clock pulse generator.

The use of the invention makes it possible to increase the efficiency of the study of the preparedness of the operator by artificially creating conditions for a forced rate of activity and identifying certain aspects of the capacity of a person, which is the most important parameter in various operator professions. The reasons for the distortions of the working level of the functional system of the operator, associated with changes in the rate of activity, and the optimum rate of activity of a particular operator for different levels of state are assessed and evaluated. Compared with the known device, the quality of operator selection is improved and there is a better opportunity to select them for work on sites with complex control systems. This reduces the number of errors made by the operator in the course of work and leads to a decrease in the efficiency of the man-machine system, and also allows the creation of systems with mutual adaptation of man and equipment in which, depending on the state of the operator, the optimal rate of his activity is chosen. .
