one

The invention relates to control equipment operator simulators and can be used as a device for training operators.

A known simulator of an operator of control systems comprising an information presentation unit connected to a control and evaluation unit and a registration unit, which is connected to the control and evaluation unit 1.

The disadvantage of this simulator is the low efficiency of the simulator.

The purpose of the invention is to increase the effectiveness of training.

The goal is achieved by the fact that it has an operative control unit, a physiological information collection unit and an eye motor activity analysis unit, while the output of the control and evaluation unit and the output of the physiological information collection unit are connected to the inputs of the eye motor analysis unit, the outputs of which are associated with the inputs of the operational control unit and the registration unit .. In addition, the operational control unit has time sensors, key circuits, counters, while the outputs of time sensors

through the first inputs of the key circuits are connected to the inputs of the counters, the outputs of which are connected to the corresponding inputs of the recording unit, the inputs of the time sensors are connected to the control and evaluation unit, and the second inputs of the key circuits are connected to the eye movement analysis unit. FIG. 1 shows a diagram of the simulator; in fig. 2 - graphs of the distribution of individual drifts in their duration; in fig. 3 and 4 - time diagrams.

Management System Operator Simulator

10 contains a software control unit 1, a unit for information presentation 2, a registration unit 3, a manual control unit 4, a comparison unit 5, an operator action evaluation unit 6, an amplifier 7, sensors 8, a block 9

15 analysis of the motor activity of the eye, consisting of an amplitude threshold circuit 10, trigger 11, two groups of selectors 12 and 13 pulses in duration and logic elements OR 14 and 15, operational control unit 16, consisting of sensors 17

20 and 18 time, keys 19 and 20, and counters 21 and 22. The control and evaluation unit has a program control unit 1, a manual control unit 4, a comparison unit 5 and

block 6 assessment of the operator’s actions. The unit for collecting physiological information contains sensors 8 and amplifier 7 ..

During the operation of the operator on the simulator, his condition is monitored by analyzing autonomous flick complexes (ROS), which are classified as rudimentary scanning movements of the Eye (RSDG). Small leaps of the eyes or flick are used as an indicator of the functional state. The analysis is carried out by fixing the values of the duration of the individual drifts (POD), i.e. the time intervals between two adjacent flicks. The AML analysis is carried out both when the gaze is fixed by the operator and in the scan mode. In the normal state of the operator, the fixing and scanning modes are characterized by an equal probability of eye leaps of 0.3-0.6 seconds.

FIG. Figure 2 shows the graph of the distribution of the AML in the fixation mode in the normal state of the operator (curve 1). If the operator enters a state of increased anxiety fear, then the distribution schedule for the AML is represented by curve 2. For other states of the operator, the nature of the distribution graph for the AMN changes.

The simulator of the operator of control systems works as follows.

The signals from the program control unit 1 are fed to the input of the information presentation unit 2. When this occurs, the corresponding lamps, transporants, etc. are highlighted. The operator, respectively, instructions, reacts to the presented signals by control actions with the organs of the manual control unit 4. In comparison unit 5, the signals from the manual control unit 4 are compared with the signals of the "ideal operator" coming from the program control unit 1. If the operator admits an error, then the output of the comparison unit 5 is a signal of the error, which goes to the operator action evaluation unit 6. The operator’s action evaluation unit 6, using the commands from the program control unit 1, calculates the operator’s evaluation estimate and transfers it to the registration unit 3, which during the operator’s work records the nature of the program, Kombey (Operator and final assessment at the end of the program).

The AML analysis is carried out in block 9 of the analysis of eye movement activity. The horizontal component of eye movements is recorded using sensors 8, the signals from the outputs of which are fed to the input of amplifier 7. In accordance with the program generated by the program control unit 1, the output of amplifier 7 is connected via controlled threshold circuit 10 to counting input of trigger 11. Signal diagram at the output of the amplifier 7, in the case of the normal state of the operator, is shown in FIG. 3 a. The dotted line in the diagram indicates the magnitude of the threshold voltage. If the signal from the output of the amplifier 7

exceeds this value, trigger 22 changes its state. In this case, at the outputs of the trigger (for Q - Fig. 36, for Q - in Fig. Sv) pulses are formed, the duration of which is proportional to the AML. The range of possible changes is subdivided into several fixed values, including the smallest, greatest, and average values. In accordance with the selected values of POD, groups of selectors 12 and 13 pulses are pre-formed in duration, which are connected to the outputs of trigger 11. Pulses corresponding to fixed values of POD pass through each selector of groups 12 and 13. These pulses from the outputs of the selectors are received in block 3 registration,

0 where the results are finalized. When the state of the operator changes, the character of the AML changes, but the operation of the circuit remains the same (Fig. 4).

The simulator also allows operational control of the operator’s condition.

5 using block 16 operational control. Operational control is carried out in cases where the operator permits errors. The signal from block 6 evaluates the operator's actions to start sensors 17 and 18, which for a certain period of time open keys 19 and 20. Through these keys, counters 21 and 22 receive pulses from the outputs of logic elements OR 14 and 15 proportional to the minimum and maximum values UNDER. The number of bits of counters 21 and 22 is chosen from the condition that, in a normal state, the number of possible minimum and maximum PODs per unit time should not exceed a predetermined value. Overflow of counters 21 and -22 indicates that the state of the operator is out of the norm. Overflow pulses enter the registration unit 3 and the program control unit 1, which can change the tempo or character

5 presented to the operator of information, thereby ensuring the adaptability of training. After a certain time, the time sensors 17 and 18 turn off the keys 19 and 20, reset the counters 21 and 22 to their original state.

0 The use of the proposed invention increases the effectiveness of the training, and also permits improvement in the process of training the operators' professional skills.
