Description

I

The invention relates to the field of automation and computer technology, in particular to simulator technology, and can be used in training control system operators.

One of the known devices for assessing the professional suitability of operators of control systems contains an operator panel, an error value determination unit, a comparison unit, a display unit, a model of the training object 1.

The specified device allows to evaluate individual actions of an operator and has a low accuracy of estimation of control system operators.

The closest technical solution to the present invention is a device for assessing the professional suitability of operators of control systems, comprising an operator console connected via a first block of matches to an error rate determination unit that is connected to the device input through the second block and directly to the first block input the comparison, the second input of which is connected to the block of input of standards, the synchronization block connected to the first and second blocks of coincidence and to the block of fixation of emergency ituatsy which is connected to the console operator error determining unit value setting unit errors and limit values indicating unit 2.

A disadvantage of the known device is that it does not make it possible to obtain an estimate of the actions of the operator for an arbitrary period of time, i.e. in cases where the management process is terminated at the initiative of the trainee when they achieve the required accuracy. The need to obtain such an assessment arises, for example, when the operator solves the problem of tracking an object on the indicator screen. In the known device, only the results of a consistent comparison of the magnitude of the average tracking error with the levels of standards are recorded. In addition, this device does not produce an assessment of the results of training for several training sessions, which characterizes the level of preparedness of this operator.

The purpose of the present invention is to improve the accuracy of the device when practicing the skill of tracking a moving object, which is achieved by shaping the current assessment of the operator’s actions with an arbitrary interval of training and assessment of his training level by the device, taking into account all previous exercises, giving the results of the assessment to both the operator and the operator. and supervisor training.

This goal is achieved in that the device contains two adders, current and resultant evaluation units and a third match unit, connected to an operator control unit, a current grade determination unit, and a result unit oueiiKH, which is connected to a display unit, connected to a current grade determination unit, which is connected through the first adder with the comparison unit, through the second adder ----- with the synchronization unit and |; en;) C 1 means from the operator.

A device for the professional suitability of operators of the y1 systems; the displays are schematically depicted in the drawing and contain the control panel 1 of the curator connected through the first unit 2 coincidence to b. 3 defined All errors 3, which through the second unit 4 coincidence are connected to the input of the device and directly; but from the first input, m of the comparison unit 5, the second input of the KOTopoio is connected to the unit 6 for inputting the standards, synchronization unit 7 connected to ) 2 and 2 second blocks 4 coincident with block 8 of emergency fixation, which is connected to operator I, 6; ioKV 3 about the definition of the unit, setting the error limits and the block 10 of the display, the third block 1 1 matches, connected to operator’s console 1, current determination unit 12 ki bloko.m 3 and determining the resulting estimates that nodklyuchsn to display unit 10 connected to the current detecting unit 12 estimates that iodklyuche; through the first adder M with a block 5 of comparison, through the second adder 15 with a block 7 of synchronization and via the operator panel 1 ----.

A device for evaluating the professional suitability of control system operators works as follows.

Commands of block 7 open blocks of coincidence 2 and 4, and in block 3 of determining the magnitude, signals are entered that are proportional to the coordinates of the tracking object developed by the simulator system and the values obtained as a result of the operator’s work. 8, block 3, the determination of the magnitudes of the errors, produces signals that are proportional to the difference between the incoming magnitudes. These signals are compared in block 5 with a valid coordinate measurement error, which is entered as a standard level from block 6. The output signal

Comparison unit 5 is generated if the magnitude of the error is less than acceptable. This signal arrives in the sumatmatmat 14, the value at the output of which is proportional} ia to the number of correct measurements. A value proportional to the total number of measurements is generated in the accumulator 15. The determination of the current assessment of the operator’s actions is carried out in the bollard 12, which receives signals from the outputs of the adders 14 and 15. The estimate is calculated as the frequency of the correct measurements and characterizes the value the probabilities P of the operator performing the task of tracking an object for each coordinate. For each accompanying object, the calculation is performed repeatedly, and the result is fed to the console display unit 10 of the manager and operator's console.

In addition, the values of this estimate, obtained by this operator while accompanying all the preceding objects and recorded at the time of completion of the manual accompaniment of the next object, are further used to calculate the level of training of this operator N. This indicator is determined in block 13 of determining the resulting estimate as the probability The fact that the deviation of the probability of accomplishing the co-existence task from the maximum possible one, equal to 1, does not exceed a predetermined value.

The magnitude of the probability deviation enters the final assessment determination unit 13 from the current evaluation determination unit 12 through the third match unit 11, which opens a signal to switch to the automatic tracking mode received from the operator console 1. In the final evaluation definition unit 13, . The deviations for all the objects with which the operator has worked are stored and stored, and the index N. is calculated.

From the output of block 13, the values of the indicator of the level of operator H's level are received by the head unit 10 of the console indication, where they are also recorded.

If the error signal at the output of the error value determination unit 3 is greater than the limit value received from the error limit setting unit 9, it passes through the emergency situation fixing unit 8 to the operator panel 1 and the display unit 10, where the excess of the measurement of the coordinates of the maximum deviation is recorded, those. gross error of action of the orator.

The proposed device can be used with a high degree of efficiency for training and training operators in practicing the skill of tracking a dynamic object. With its help, the training manager provides current information.
