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

When the power is turned on, the registration node 15 is reset, triggers 4, 5 and 22 and. generator 11 is started. In addition, indicator 24 is turned on, allowing the operator to press a key. With the help of switch 21, a delay is set for the resolution of the response input, equal to K – rd, where K is 0,1,2, ..., (, is the duration of the reference signal. In the first mode, the operator listens to a single pulse and remembers its duration. For That is, he presses the key 2 on the remote control 1. The pulse from the output of key 2 through the open element I 3, since the second trigger 22 in its initial state has a potential at the output connected to the input of the element 3, simultaneously arrives at the counting input of the trigger 4 work, the single input of the first trigger 5 and element 8. At this ohm the trigger 4 enters a state in which a high potential appears at its output connected to the element And 7 of block 6 and the second element And 16. A high potential from the single output of trigger 5, the element And 7 is opened, 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 input of the electroacoustic converter 10 and through the second element ШШ 23 to the input of the first element AND 12

The operator listens to the sound of your pulse image. The duration of a single pulse is set by changing the frequency of the generator 11 using a switch (not shown). Pulses from the output of the generator 11 are received through the open first element 12 at the input of the counter 13. The transfer pulse from the output of the first counter 13 through the open second element 16 and the open element 11 enters the zero input of the trigger 5 and the single input of the second trigger 22 delays. The trigger 5 is transferred to a state in which a low potential appears on its single output, which closes the element AND 7, which causes the form-. the trailing edge of a single pulse in the first mode. At the same time, the indicator 25 also goes out.

The trigger 22 is switched to a state in which a low potential appears at its zero output and a high potential at one output. With the appearance at the zero output of the second low potential trigger 22, the AND 3 element of the remote control 1 is closed, and the key 2 is thereby blocked, and the indicator 25 turns off, warning the operator to prohibit work with the key 2. The lock prevents the device from being accidentally or prematurely pressed by the key 2.

The high potential from the single output of the trigger 22 delay opens element 18 and the second element OR 23 opens the first element 12. At the same time, the transfer pulses of the first counter TK through the open elements 16 and 18 arrive at the third counter 20. Appearance 1 of the transfer pulse corresponds to the 5 delay introduced for resolution of the response, equal to Gd, where 0 is the duration of the reference pulse. The appearance of the Kth pulse corresponds to the KG delay. The number n, and therefore the input delay 50, is set by the switch 21. The appearance of a transfer pulse at the output of the first delay counter 20 through the switch 21 leads to a change in the state of the second trigger 22 by switching on the delay.

The trigger 22 returns to its original state, in which the signals with

its output opens AND 3 (key lock 2 is released), indicator 24 is turned on, allowing operation with key 2 and AND 12 is closed.

In the second mode, the operator presses the key 2, maintaining the duration of pressing p. The number n 1,2,3, ... is set in accordance with the methodology of the simulator. The signal from the key 2 through the open element And 3 enters the counting input of the trigger 4, the single input of the first trigger 5 and the input of the element And 8. In addition, simultaneously from the second contacts of the key 2 (not shown) connected to the second inputs of the counters 13, 14 and 20, a short pulse is applied to reset them. The trigger 4 enters a state in which a high potential appears at its output, which opens element AND 8. At the other input of element AND 8, a high potential flows from key 2 and through the open element AND 8 and the first element OR 9 passes to the input of the electroacoustic transducer 10 and through the second element OR 23 to the input of the first element AND 12. The operator can control the duration of the formed pulse by ear.

The pulses from the output of the generator 11 are received through the open first element 12 at the input of the counter 13. From the output of the first counter 13, the transfer pulses enter the input of the second counter 14. From the moment key 2 is turned off, the first element 12 closes and the input to the counter 13 of pulses stops output of the generator 11. The counting results of the counters 13 and 14 are rewritten into the node 15, in which the results of the first test are recorded. Node 15 also records the magnitude and nature (more or less) of the error made, namely, the conversion factor of a single pulse and the conversion error.
