The invention relates to auto-telemetry and telemechanics and can be used to control a large number of objects operating sequentially one after the other in time, and is an improvement of the distributor according to aut. St. G.

The purpose of the invention is to expand the scope by additionally providing control of the distributor directly from each cell.

The drawing shows an electrical diagram of a reversing pulse distributor.

A reverse impedance distributor consists of series-connected cells, each of which contains, respectively, a high-speed relay, a slow-motion relay C-6, a diode bridge, decoupling diodes 10 and 11, 17. and 13, And 15, the first 16 and second 17 power buses. , control input 18, power buttons, switches 22-24. the cell switching direction line 25, a switch 26 containing a closing contact 26.1, a first 26.2 and a second 26.3 switches.

Reversible pulse distributor works as follows.

In the initial state, all relays and remote switch are disconnected by disconnecting the supply voltage. To select the cell switching direction, it is necessary to set the switches 22-24 to the appropriate position. In this case, in the case of objects operating in the forward direction, the switch 26 is disconnected, and in the case of objects operating in the opposite direction, the switch 26 is turned on and becomes self-locking. Switching is switched on via a circuit plus a power source - the corresponding contacts of switch 26.2 of switch 26 - power bus 16 (with switch disconnected) or bus 17 (with switch on) - bridge diode J, 8 or 9 - switch 22,

23 or 24 - line 25 - switch

26 - minus power source. Self-blocking of the switch 26 is carried out by closing contact 26.1. After that, switch 22, 23 or

24 is set to the neutral position.

Consider the case of switching cells (object robots) in the forward direction. To turn on the first cell, press the power on button 19. At that, the quick-acting relay 1 turns on and becomes self-blocking and supplies power to the slow-motion relay 4. Relay 1 turns on along the circuit plus the power source corresponding contacts of the switch 26.2 of the switch 26 - power bus 16 - bridge diode 7 - power button 19 - winding of the high-speed relay 1 - disconnecting contact 4.2 slow relay 4 - bridge diode 7 - power bus 17 - corresponding contacts of switch 26.3 of switch 26 - minus power source. Self-blocking of the high-speed relay 1 is carried out by means of the closing contact 1.1. According to the same circuit, the delayed relay 4 is supplied with power.

After the set shutter speed has elapsed, the slowed down relay C is activated, the disconnecting contact 4.2 of which breaks the power supply circuit 1 and turns it off, and one of the closing contacts of the relay 4 prepares the switching circuit of the relay 2 of the second cell of the reverse pulse distributor. Relay 2 is connected along a circuit plus a power source - corresponding contacts of switch 26.2 of switch 26 - power bus 16 - closing contact 4.3 relay 4 - diode 12 - relay 2 winding - disconnecting contact 5.2 relay 5 - bridge diode 8 - power bus 17 - corresponding switch contacts 26.3 switch 26 — minus the power source. Relay 2, when turned on, becomes self-blocking. At this point, the relay 4 of the first pulse pulse distributor switch is turned off. For normal operation, the following condition must be met:

- holding time in the on state of the closing contact of the relay 4 after power is removed; on and on time of relay 2.

The delay for switching on the delayed relay is usually chosen sufficient to test the installed program of the actuator of the cell of the reversing pulse distributor, which can be activated by the contacts 1-3 of the relay.

Relay 3 is turned on in the same way, after which the circuits of the next cell of the reverse pulse distributor, etc., are prepared. Thus, during the operation of the reversing valve, the slowed down relays are sequentially turned on and off, preparing the On circuit of each subsequent cell, and the high-speed relays are turned on only for the period of activation of the actuator of the control object, after which they are turned off.

To return the reversing distributor to its original position, the supply voltage is turned off (the power off system is not shown).

Consider the case of switching cells (operation of objects) in the opposite direction. To do this, it is necessary to set the direction of cell switching using the switch 22, 23 or 24, as described above. As a result of switching on the switch 26, the polarity of the applied voltage in the power supply buses 16 and 17 is allowed. Supposedly, the on button 21 turns on the high-speed relay 3 of the third reversing distributor cell. The holding circuit of the relay 3 and preparation for switching on the relay 6 is as follows: plus the power source - the corresponding contacts of the switch 26.3 of the switch 26 - the power bus 17 - the bridge diode 9 - the closing contact 3-1 of the relay 3 winding relay 3 and 6 - the disconnecting contact 6.2 of the relay 6 - the diode bridge 9 — power bus 16 — corresponding contacts of switch 26.2 of switch 26 — minus the power source. Relay 6, when turned on, prepares the switching circuit of the relay 2 of the second cell. In this case, the relay 2 is switched on along the circuit plus the power source — the corresponding contacts of the switch 26.3 of the switch — power bus 17 — closing contact 6.1

relay 6 - diode 13 - relay 2 winding - disconnecting contact 5. relay 5 - bridge diode of power supply pin 16 - corresponding contact of switch 26.2 of switch 26 - minus power supply, etc.

Thus, a reversible pulse distributor has a wider field of application due to the possibility of setting the direction of cell switching movement and switching it on from any cell (object) directly from each cell.
