 34, 1: 35, block 36 of the mode of operation, element OR 37, element 38.

Unit 36 contains an inverter 39, the node 40 mode selection and the element And 41.

In addition, the device contains information bus 42-44,

The device works as follows.

The operator, using the indicators of block 4, presents the signals to which he must respond using the keys of block 1. The program of information signals is set by the switch 3, the time allotted for the action to be performed by the driver 5. Correct answers that the operator put into the allotted time interval are recorded by the counter 7 and displayed on the indicator 18. At the same time, continuous control of the strength of the operator’s actions is carried out by measuring the electrical resistance of his skin and maintaining optimum the level of intensity of action in a given interval using block 9 due to a change in the time allotted for the response, t, e. changes in the duration of the time intervals of the imaging unit 5 and the display of these changes by indicators 19 and 20 to stimulate the subject to enter the optimal zone.

When the power is turned on, the switch 3, the triggers 15 and 16 of the block 9 and the block 4 are reset.

The device can operate in the modes of training and control of operator knowledge. The mode of operation of the device is set by training using block 36,

In the Training mode, at output 42 of block 36, there is a high logic level that opens AND 38, while closing element AND 41 of block 36. At output of AND 41 there is a low logic level.

The operator, through the indicator 17, presents the signals of the functional control of the technological state of a complex ACS in the form of digital codes from the switch 3 through block 31 and node 21. According to these codes, he must decide on the failure of one or several nodes of a complex ACS and print off using cla3

Vnsh block 1. Information about the noncirculated node of a complex ACS is embedded in a small number of combinations of a digital code, as well as in the meaning of the digits themselves, which requires complex logical processing.

Automatic processing of information from block 31 is performed by block 32.

The malfunction signals generated by block 32 are received at one input of block 2 and at one input of block 33, the other inputs of block 2 receive signals from block 1 when the keys are pressed, the correct answers, which the operator put into the allotted time interval, are recorded by the counter 7 and are displayed on the indicator 18 by means of the former 23. In this case, the learning time is automatically adjusted by setting the register 8 to the idle state of the pulse with the correct answer, coming through the OR 37 element at the input 44 sd flashing register 8, Shaper 5 generates a signal for a new task,

 In case of an incorrect answer, the operator repeats the call to the new answer or may press the button I don’t know in block 1, all operator’s actions are recorded in the counter 35, When I press the button I don’t know the signal from block 1 goes through element 38 to block 33 and the recorded ones are skipped in block 33 of information signals of block 32 to shaper 24 which generates a signal of the operator's correct actions according to the information presented to him. Information of the correct answer of the operator from the driver 24 is reflected on the indicator 18. When you press the keys I don’t know the signal through the register 34 enters the counter 35, while the number of pulses corresponds to 1/5 of the pulses

Research Institute to the new answer. Further, the operator continues to process information on new malfunctions of a complex ACS,

In the Control mode, there are two possible options for the operator’s response, correct and incorrect,

In this mode, the output 42 of the block 36 has a low logic level. In this case, element 38 is closed than 10, it is impossible for the operator to obtain information about the correct answer when the button is called. I don’t know. If the correct answer of the device is 15, it is similar to working in the Training mode,

In case of an incorrect answer, the operator presses the Call button of the task in block 1. At the output 20 of the block 1, a pulse is generated that passes through the open element AND 41 of the block 36, the OR 37 element at the input 34 of the register 8, and with the help of the driver 5 it calls Information 25 about the new task.

Based on the readings of counters 7 and 35, it is possible to calculate the degree of operator training,

During the operation of the device, 3Qa provides continuous control of the intensity of operator actions. Switching off and on the information. the mapping signals is performed by a driver 5, which controls the switch 3 and the driver 22, which produces a blanking signal,

The use of the invention in devices for the selection and training of functional control operators in complex automated control systems that require large psychological stresses increases the accuracy of the assessment of the level of operator training, reduces the time the operator works with the device, i.e. increase the capacity of the simulator as a whole.
