Description

Known pulse generators are designed for the issuance of a continuous sequence of pulses. Similar devices do not provide a series of pulses with a predetermined number of pulses from a series, which makes it difficult to use such generators in automation and telemechanics.

The described method for controlling a pulse generator and a device for carrying out this method allow to obtain a given number of pulses in a series. The duration of the first and last pulses in each series is equal to. The described method consists in the fact that the trigger circuit that controls the output stage of the working impulse generator is fed using the switching key with the same starting impulses that are used as a booster and as driving pulses.

A device for carrying out the method comprises a working pulse generator, a starting pulse generator and a trigger device. The release device has a polarized relay output that shunts the output stage of the operating pulse generator in accordance with the control signals.

A schematic diagram of a pulse generator control device is shown in the drawing.

Sinusoidal oscillations from the generator 1 through the shaping device 2 affect the sawtooth generator 3. The generator 3 is connected via limiter 4 to the output stage 5. The output pulses are removed from terminal 6. Output stage 5 can be grounded by the relay contacts. In this case, the signals on the clamp 6 is not received. Shunting of the output stage is controlled by two relays. One of them, polarized, is included in the anode circuit.

№ 133499- 2 lamps 7 and 8 rheostatic trigger. The windings of a polarized relay 9 are connected in a differential circuit.

The trigger is controlled by grid circuits through cathode repeaters made on 10 11 w lamps. operating in limiting mode. The beginning of the pulse train is detected by the activation of the second control relay (not shown) of the telephone type. When this relay trips, contacts 12 and 13, / 4 and / 5 open, and contacts 13 and 16 close. Positive pulses entering the grid of the lamp 11 from the forming device 2 overturn the trigger into a steady state of equilibrium, at which the polarized relay 17 flies to contact 18. On day off; pulses appear. At the end of the series releases the second telephone-type relay (not shown in the drawing). Contacts 12 and 5 are closed. The trigger occupies a second steady state of equilibrium, and the switch of the polarized relay 17 goes to pin 19. Exit stage 5 is bypass. Impulses to clamp 6 are not received. If necessary, a pulse counter can be connected to terminal 6, which is connected to the starting telephone relay. After counting the desired number of pulses in a series, the counter causes the start-up relay to be released, resulting in a bypass of the pulse generator output.
