The drawing shows the functionality of the circuit of the proposed device. As an example, a diagram with five information controls These inputs, i.e., the device contains information control inputs, which are connected to the input of the OR element through the OR element. 6 of the synchro pulsation unit 7, the output of which through the switching element 9 is connected to These inputs of triggers TO-1, one of the inputs of element 15 are connected to the second output of trigger 10 and the fourth input of trigger 1.1, the second inputs of elements 1518 are connected to the second outputs of triggers respectively, and the inputs of the previous elements connected to the inputs of the subsequent elements I. The output of the element I 18 is connected to the second inputs of the 10th trigger and the second dynamic input of the second element OR 8. The encoder 19 signals, built on the elements AND ZO.-i, has outputs 25-29, which through it. The nickname of the connection is connected to the Objects of the tele-. Equations (not shown). The device works only when there is a response signal from the telecontrol object arriving at the AOR inputs of the feedback of the element OR 8 of the circuit 7. The first inputs of the AND 20-24 elements are connected to the first outputs of the trigger of the 10th corresponding bits, and the others The inputs of the elements And 20-24 noj are connected to the second outputs of the trigger 10-14 previous bits. The device works as follows. In the initial state, on the information control inputs 1-5 there is a prohibiting potential O, by which the triggers 10-1.4 are set to 4 and the O state, and on the outputs 25-29 of the encoder 19, the O signal is set. On the second and fourth triggers The 10th potential 1 is present, at the feedback inputs of the AOR-3 potential O. Dynamic inputs of the element OR 8 work only in case of a potential drop from M, element 9 is triggered by a difference from 11 to O. Triggers the 10th transition to another stable state only in case of impulse action on tert th input if you have permission to vtor1H and fourth inputs. Consider the operation of the circuit in case of arrival of the signal 1 to the information control inputs 1, (and 5. In this case, the first inputs of the triggers, 10, 13, and And see 1, i.e., the triggers are unlocked 1 in and out the inputs of the OR element. the output of which is the difference from O to 1 acting on the dynamic input of the element OR 8 and at its output, in turn, appears a pulse triggering element 9 at the output of which a positive pulse appears. switch element 9 unlocked triggers 10, 13 and 14 g | tree mc -. in state 1. On the second inputs of the 10-I-triggers O is set by the signal. From the output of the input element And 18 .. At the K-inputs of the tl-l4 triggers, the signal O is set. Elements 21-24 are blocked by O From the second output of trigger 10 and at outputs 26-29 there is a signal O, at output 25 a signal .1 of the first output of the trigger is 17. This signal goes through the communication channel to the telecontrol object and through the time delay in the communication channel to the input 30 feedback element OR 8 signal comes, which is the response to the execution of the command. This signal, through the element OR 8, starts element 9 and, at the end of the pulse from element 9, the trigger TO moves to the zero state. On. output 25 appears on signal O, elements 21-24 of encoder 19. are unblocked, and since at the moment of arrival of the pulse from element 9 on the fourth inputs of triggers 11-14, the signal O was present, these triggers remained in the same state ( 11.12 -. 13, and - 19

and at output 28, Wits signal 1. Element I 2 at this time blocking the second output of trigger 13. From output 28 1 enters the communication channel. After the arrival of the response signal from the communication channel, input 33. Element 9 is launched through the second element OR 8 and the back edge of the pulse from element 9 is triggered 13

in the state O, since the fourth input of this trigger contained signal 1 from the element I 1b. As soon as trigger 13 enters state O, the element AND 2 / is unblocked and a signal 1 is sent from the output of this element to the communication channel. The response signal arrives from feedback input 3, then element 9 and the trigger AND the back of the pulse from element 9 is transferred to the state

at output 29, the Wits signal

linn

O Scheme returned. In original condition. At the moment of switching the trigger to the state O, a potential drop from O to 1 occurs at the output of the element AND-18, which, acting on the dynamic input of the element OR 8, starts element 9. The rear front of the pulse from element 9 triggers 10, -13 and 14 cs to state 1 and the cycle repeats.

The proposed device can operate as a conventional pulse distributor. In this case, the outputs 2529 through the delay elements are connected to the corresponding inputs of the element OR 8.

The proposed construction allows cyclically receiving any combination of pulses at the outputs of the encoder with a given sequence within the combination. The device is comparatively simple in design due to the absence in the || scheme of synchronization of the synchronization pulses of the external pulse generator and is a closed-loop telecontrol system.
