Description

The invention relates to the field of automation and computer technology and can be used in the selection, training and control of the characteristics of operators - in the control circuit of man-machine sets, for example, drivers of motor vehicles.

A known system of automatic control of operator parameters in a control loop, containing a decoder-distributor connected to a warning indicator, their signals, an alarm indicator, a random number generator, an address device controlled by a pulse generator and a time interval sensor, remembers its device, the input of which is connected to the random number generator and the addressing device, and the output to the master indicator, connected in series with the control unit, the new control unit, the sensor unit, and the computer Rator and recorder, reaction sequence analyzer and time interval meter, the first inputs of which are connected to the first input of the comparator, the second inputs to its second input and through the driver of the reference signals to the address device, and the outputs to the recorder, analog-digital converter, whose input is connected with the output of the comparator, and the output with the corresponding input of the recorder, and a program-control unit connected to

a distributor-distributor controlled by a pulse generator, an addressing device, a memory device, a shaper of reference signals, a sensor unit

and the registrar.

The system made according to the invention differs from the known one in that it contains series-connected oscillator, the control input of which is connected

with a decoder-distributor, an electromechanical transducer, the other input of which is connected to the output of a memory device, and a mechanical effect simulator, the input of which is through the transducer

mechanical forces are connected to the output of the control unit, the voltage converter, the input of which is connected to another input of the comparator, and the output - to the master indicator, the resolver, the counter

faults and a fixing indicator, the resolver being connected directly and via a fault counter to a fixing indicator, which is also connected to the first output of the time sensor,

With the reaction sequence analyzer, with the time interval meter, with the analog-digital converter, with the recorder, with the second output of the time interval sensor and the program-control unit, which is also connected to the control inputs of the mechanical effort converter and the voltage converter.

This makes it possible to increase the efficiency of control and the reliability of the data obtained.

The system of automatic control works as follows.

Operator 1, whose characteristics are determined and monitored, receives instructions for execution from the master indicator

15 and specific information about the situation from the indicators 17, 26, 18, simulator 21 and then performs the necessary manipulations with the appropriate controls of unit 3. After converting the voltage to the sensor unit 3, the voltage goes to the comparator 4, the analyzer 6 of the reaction sequence Operator 1 and 7 V | Belt and Terval Meters, in which it is compared with a reference signal corresponding to the ideal (or optimal) operator response for a given situation, coming from the driver 19 reference signals. The result of the comparison is recorded by the recorder 5 and, in addition, fed to the resolver 9. The signal from the output of the comparator 4 is pre-converted into digital form using an analog-to-digital converter (ADC) 8.

The frequency of the instruction to the operator is determined by the controlled pulse generator 10, and determined by the program-control unit 11. The selection of the mode of operation is performed by the decoder-distributor 12.

A set of all possible commands is stored in the storage device (memory) 14, and they are presented to the operator 1 using the master indicator 15.

Commands to operator 1 can be supplied in the form of sample test sets, which corresponds to the majority of real situations where the operator must respond to a whole number of interconnected typical disturbances.

(teams). In this case, signals to select commands from memory 14 come from address device 13.

In the other mode, the operator 1 is given a sequence of commands that are not related to each other, i.e., the operator is modeled in unpredictable situations. In this case, the selection of commands from memory 14 is determined by a generator of 16 random numbers.

Monitoring the parameters of operator 1 when working in stressful situations is modeled by sending signals of an extreme nature, for example, light and sound signals of considerable intensity (or a rare type), from the emergency indicator 17.

The ability of the operator 1 to adapt and to likely predict situations in the presence of additional redundant information is monitored in the mode when special anticipatory next command or command set of signals from the indicator 18 are given.

In a real situation, in most cases, the operator has a feedback signal, i.e., the result of executing the command, which allows him to optimize his subsequent actions.

The mode of operation in such situations is modeled by giving feedback signals to the output of the control unit 2 and the sensor unit 3. Their output signals; 1Ы, formed by a transducer of 24 mechanical forces and a transducer of 25 voltages,

arrive, respectively, on the pmitator 21 mechanical effects and setting indicator 15.

The presence of these feedback signals significantly improves the reliability of

operator I control in the modes described above, this is especially true for emergency operation. In this case, catastrophic failures in

complex whose link is operator 1.

The reliability of the data obtained is also increased due to the introduction of the generator of the noise generator 22, which gives signals to the indicator

15 and through the electromechanical transducer 23 - to the simulator 21. This mode corresponds to work in a real situation, i.e. in the presence of interfering factors of different nature.

The presence of a solver 9 that performs real-time processing of all the data coming from the ADC 8, meter 7 and analyzer 6, allows you to control the ability of operator 1 to optimize their actions, and to adapt and to learn. The resolver 9, continuously or at the instants of time determined by the program-controlling unit 11, outputs to the fixing indicator 26 information about

results of operator 1, for example.
