Description

(5A) PULSE DISTRIBUTOR-COUNTER

-. one

The invention relates to a pulse technique and can be used to build devices for counting and distributing pulses.

A conversion device is known that contains cells on thyristors, a relay and a propulsive pulse generator .1.

The disadvantage is low reliability. A pulse counter is also known, which contains a control unit and cells on two relays and three diodes each 121.

The disadvantage is that the change in the duration of the day off is limited; pulse, determined by the time of the relay, i.e. low; functionality, and hence the consumption of energy is proportional; number of cells.

The purpose of the invention is to expand the functionality and reduce power consumption.

The goal is achieved by the fact that a pulse shaping unit containing the control unit, the first and second power buses and the counting cells on two relays are inserted into the first triggering pulse forming unit on the relay, one winding terminal of which is connected to the first power bus via a serial RC chain,

10 in parallel with which a counter-polarity diode of the supply voltage is connected, in the counting cells one output of the winding of the second relay through the switching and opening contacts of the first

ts group of the first relay of the next cell is connected to the closing contacts of the first and second groups of its relay and, in all counting cells except the first, to the closing contact 20 tOM of the second group of the first relay of the previous counting cell, switching contact of the second group of the first, the relay of each counting cell is connected,

3-9 with the output of the control unit, the first winding terminal of the first relay is connected to the switching contact of the first group of the second relay, the switching contact of the second group of the second relay is connected to the second power bus, where the midpoint of the RC chain is connected, the second winding terminals of the first and second relays connected to the first power bus, closing the KOHtaKT of the first group of the second relay. The first cell through the switching and closing contacts of the relay group of the first triggering pulse forming unit is connected to the output of the control unit.

The drawing shows a schematic diagram of the device.

In accordance with the scheme, the device includes a control unit 1, counting. cells, ..., containing relays 3 with contact groups and, relay k with contact groups and 2, the first power supply bus 5, the second power bus 6, a triggering pulse generation unit consisting of a diode 7, a capacitor 8, a relay 9 with the contact group and the resistor 10, as well as the outputs of 11,12, ..., n cells.

The device works as follows. ;

When voltage is applied to the power buses, condensate par 8 is charged through the winding of the relay 9 which is activated and the contacts of the group connects the winding of the relay k of the first cell to the output of the control unit 1, from which the voltage pulse is sent to the relay winding k , it blocks itself through the contacts of the group, and through the contacts the voltage is applied to the relay 3 winding. At the same time, the output 11. the first cell appears. The contact opens 1 | 1e, the relay groups 3 opens, and the closing contacts of the group close and connect ayut relay coil 4 of the second cell to the output of the control unit 1. The second impulse from the control unit 1 triggers the relay 4 of the second cell, which blocks itself through the contacts of the group, which causes the appearance of voltage at the output 12 of the second cell.

The contacts of the second cell group connect the voltage to about, 4

the coil of the relay 3 of the second cell, at this time the contacts of the group of the second cell, which unlock the relay 4 of the first, are thrown

cells, at the output 11 of which the voltage is released. The contacts of the second relay of the second cell connect the winding of the relay 4 of the subsequent cell to the control circuit. Thus, at the outputs of the cells, the voltage from the Titanir source appears in series, the duration of which is determined by the pulse period of the control unit 1, while only two relays of one cell are connected to the power source. After the arrival of the nth pulse at the exit of the nth cell, the voltage pulse is given. If necessary, the distributor-counter can operate in a ring mode, for which it is necessary to connect the corresponding conclusions of the f-elements and the cells with the corresponding conclusions of the 1-and

cells by analogy with the connections between 1st and 2nd cells and. The device returns to its original state by relieving the voltage from the power bus, while the capacitor

8 is discharged through resistor 10 and dis) d 7.
