The invention relates to automation and computer technology and can be used for training operators of control and monitoring systems for the functional state of operators, as well as for professional selection.

The purpose of the invention is to expand the didactic capabilities of the simulator.

The drawing shows a structural: circuit simulator.

{Simulator of the operator of control systems; contains the panel 1 of the operator consisting of the key 2 connected in series, element 3 and trigger 4 operating modes, second trigger 5, the first block 6 elements AND, the CONSTANT of two elements AND 7 and 8, the first element OR 9, electroacoustic generator 10, fixed frequency generator 11, first element 12, first counter 13 (conversion errors), second counter 14, registration node 15, second element 16, second block 17 of elements AND consisting of elements And 18 and 19, reversible counter 20, encoder 21, Datch to 22 random numbers, the second OR element 23, the indicator 24 and indicator razrep1eni answer mode 25, the trigger 26.

Converter 10, node 15, indicators 24 and 25 are combined in block 27 of presentation of educational information.

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

When the simulator is turned on, the registration node 15 is reset, triggers 4, 5 and generator 11 and random number sensor 22 are started. In addition, indicator 24 is turned on, allowing the operator to press key 2.

In the first mode, the operator listens to a single signal and remembers its duration. When key 2 on the remote control 1 is pressed, the pulse from the output of key 2 through the open element I 3, since the third trigger 26 is in the initial m state and has a potential at the output, connected. with the input of the element And 3, simultaneously enters the counting input of the first tri1- | -er 4 of the operation mode, the single input of the second trigger 5 and the element 8. At the same time, the first trigger 4 passes into the state when its output connected With element 7 of block 6 and the second element and 16, a high potential appears. A high potential from a single output of the second flip-flop 5 arrives at the other input of the element 7, so the element 7 opens and the signal from its output goes to the input of the indicator 25, including it, and then through the first element OR 9 to the electroacoustic input the converter 10 and through the second element OR 23 to the input of the first element of And 12. In addition, the pulse from the output of the element And 7 goes to the third input of the reversible counter 20, allowing

thereby recording information from the sensor 22 random numbers through the encoder 21.

The duration of a single signal is set by varying the frequency of the generator 11 using a switch (not shown). The pulses from the output of the generator 11 through the open first element And 12 to the input of the counter 13. The transfer pulse from the output of the counter 13 through the open second element And 16 and the open element And 19 enters the zero input of the second trigger 5 and the single input of the third trigger 26. Trigger 5 is transferred to a state in which a low potential appears at its single output, which closes the element 7, which causes the formation of the trailing edge of the monitored single signal in the first mode. At the same time, the indicator 25 also goes out.

The trigger 26 is switched to a state in which a low potential appears at its zero output, and a high potential at its one. With the appearance at the low output of the low potential trigger 26, the element AND 3 of the control panel 1 is closed and the key itself is blocked by the key 2, which eliminates the possibility of accidental or premature pressing of the key 2 by the operator.

The high potential from unit 1 of the trigger output 26 opens element 18 and the second element OR 23 opens the first element 12. At the same time, the transfer pulses from the output of the first counter 13 through the open elements 16 and 18 are fed to the subtracting input of the reversible counter 20. The 1st transfer pulse corresponds to the entered delay to the response resolution, equal To, where Co is the duration of the reference pulse. The occurrence of the k-ro pulse corresponds to the delay k to- The number k, and therefore, the input and delay. It is determined by the state of the m of the equal-frequency non-repetitive sampling unit 22. For example, an equipotential unit can have 8 outputs, and when it is first accessed, a signal can appear equally equally at any of the 8 outputs. Let the signal, for example, according to the wils at the 6th exit. Since the outputs of the equipotential block 22 are connected via an encoder 21 to a reversible counter 20, the number 6 in binary code will be written into the reversing counter 20. Thus, a delay will be introduced.

On subsequent calls to the random number sensor 22, the signal will equally appear on any of the remaining outputs. In the considered example, the cycle consists of 8 calls, during which 8 time delays will be used, and the order of their use is random, which eliminates operator presetting and will increase the intensity of his work.

During further operation of the simulator, the cycles will be repeated, but the order of time delays input in each number will be different.

A transfer pulse from the output of the first counter 13 arrives at the subtracting input of the reversible counter 2. As soon as the contents of the reversible counter 20 become zero, a signal is output at its output that goes to the zero input of trigger 26 and changes its state. At this, signal from trigger output 26 opens element 3 (key 2 is released), indicator 24 is turned on, allowing the operator to work with key 2 and, besides, element 12 also closes because the output of trigger 26 connected to it is zero potential.

In the second mode, the operator presses the key, maintaining the duration of pressing n t. The number n 1, 2, 3, ... is set by the instruction.

In this case, the signal from key 2 through the open element I 3 enters the counting input of trigger 4, the single input of trigger 5 and the input of element I 8. Besides, from the second contacts of key 2 (not shown), a short pulse is applied to the second inputs of the counters 13 and 14 to reset them.

The trigger 4 does not return to a state in which a high potential appears at its output connected to the input of the element And 8. A high potential from key 2 arrives at the other input of the AND 8 element. Therefore, a signal appears at the output of the AND 8 element, which is fed to the sensor input of 22 random numbers and to the input of the first element Or 9. In block 22, the output is selected and the next entry output in binary code with the encoder 21 to the reversible counter 20. Through the element OR 9, the signal passes to the input of the electro-acoustic transducer 10 and through the second element OR 23 to the input of the first element AND 12. The operator. formed signal.

The pulses from the output of the generator 11 come through the open first element I 12 to the input of the counter 13. From the output of the first counter 13 and the transfer pulses go to the input of the second counter 14. From the moment the key 2 is turned off, the first element 12 closes and the input counter 13 pulses from the output of the generator 11. The counting results of the counters 13 and 14 are rewritten into green 15, in which the results of the test are recorded:
