Description

Device for remote control of those connected to a power network Receiving apparatuses It is known to have receiving apparatuses connected to a power network by superimposed control currents of non-network frequency, in particular audio frequency, or by briefly switching off or reducing the: Mains voltage to be remotely controlled. If the different remote control acts are not perceived by special control frequencies want to execute, you can, for example, the individual acts by different numbers of pulses vont: differentiate from one another. One then comes with a single control frequency for all remote control files. It is known with your last-mentioned remote control experienced to use receiving relays, which when each pulse arrives a control organ, for example by means of a Klinkwerk step by step. The tax organs of the various receiving relays connected to the power network can thereby brought into any position and each position can be a certain remote control act be assigned. With such a relay, however, there is a risk that once If a switching step or an impulse is missing, the control organs are in disarray advised without the remote control center being able to perceive this.

In order to eliminate this danger it has been suggested to use the control unit to let a retraction force and a damping device act that the effect have that after each remote control act and already during the same the control organ is moved back to its original position with a certain delay. The from Control member operated control part, z. B. a switch, is at such a distance attached from the starting position of the control member that it is only actuated by this «- can earth if the incremental pulses follow one another quickly. The number of incremental pulses is meaningless for the operation of the relay, the only requirement is that at all more than two or three impulses are sent, otherwise the control unit will not to the control unit. is advanced. 'With such means only one execute single type of remote control files.

Receivers for overlay remote control systems are also known, In addition to a resonance organ tuned to the superimposition frequency, there is also one Time dialing device, e.g. B. have a drive driving a controller. These Devices are not driven by different numbers of pulses, but by pulses different durations activated or selected. With remote control by reducing the voltage can Such devices are not used because with consideration for the rest of the network connected devices, the voltage can only be reduced very briefly allowed. The invention has the task of working with different numbers of pulses Remote control devices to increase the number of possible remote control files. The consistently Similar impulses can come from superimposed currents of non-network frequency or consist of voltage drops.

According to the invention, the receiving devices have next to one by the remote constant pulses actuated resonance device or voltage drop relay for the control of an indexing mechanism one that is under the action of a retraction force and operated by the indexing mechanism Control body. Furthermore, only takes place after a certain advance path has been covered with the backward movement of the control element the switching process takes place, with smaller ones or greater incremental paths, on the other hand, the control section returns without executing the switching process back to the starting position.

The invention will be explained in more detail with reference to the drawing.

i is the power network, which for the purpose of remote control finit audio frequency is overlaid from any central unit. 2 is a receiving apparatus that consists of your resonance relay 3 with your ballast capacitor .I, the Ylagnetspule 3, your Arm 6, the pawl 7 and the ratchet wheel 8 consists. The spring 9 searches the arm 6 in to push the rest position caused by the stop io, in which the pawl 7 through the stationary finger i i held out of your area of the teeth of the ratchet wheel 8 will. For this purpose, the pawl is provided with an extension 12 serving for guidance Mistake. 13 is another stationary control part for the extension i.1 of the latch, which has the task of the pawl j in the working position of the arm 6 ini area to keep the teeth of the wheel 8, but the parts 13 and 1q. also drop out. When moving the arm 6 in the arrow direction, the pawl can; the teeth of the ratchet wheel 8, if the opposite movement occurs, the ratchet wheel will 8 taken along in the sense of the arrow drawn in and advanced with a tooth.

The control arm i6 and the ratchet arm i are seated on the shaft 15 of the ratchet wheel 8; finite of the pawl 18, which engages in a ratchet wheel 20 connected to the damping trough disk icr. The breaking magnet 21 acts on the disk 19. The spring 22 searches for the parts 8, 16, 1; to turn back into the starting position caused by the stop 23 for the part 16. This looking back can slowly take place cool because doing this through the latch arm 1; the Brake disc i9 must be taken along. When shifting forward in the sense of- on, drawn arrows is the braking device ineffective because the pawl 18 over the ZIine the wheel slides 2o. Ani outer end of the rudder "@, @ ans 16 is vain feather 2;. attached that in axial Direction can evade. In the way de_- The filter door piece 23 is stationary in the spring 2I arranged, the two parallel, oblique to the Stepping travel of the spring 2-l. lying foreheads 2f @, 2; and two parallel to the stepping path running flanks 28, 29 has. On the website the edge 28, the control switch 30 is on arranges it in such a way that it is only at the Return of the Arines 16 is closed. zz-allrend with the forward movement the- seArines merely a spreading ring, the con- feaktdern results. The device works as follows: iidermalicii: If the switch 30 is to be closed, then Zierden sent so many impulses that (read Stepping mechanism 7, 8 the control arm i6 to in brings the position shown in dashed lines i6o. With each impulse the magnet 3 pulls the in it 6, the pawl 7 slides flawlessly over the teeth of the wheel 8. As long as the impulse lasts, the clink is kenra (18 blocked by latch 7: at Cessation of the impulse returns the: 1, rni 6 in back to the position shown, the latch; advances the wheel 8 by one tooth.

These relays are remotely controlled in that, just as in the case of the receiving apparatus 2, the switch 16 is advanced by a certain distance. The stepping path must, however, be greater or smaller than that which is required to operate the apparatus a. However, this apparatus is not influenced by these other indexing paths, which of course also the arm 16 of the apparatus: 2 participates, because with smaller indexing paths the spring reaches 2q. not switch 30 at all; In the case of larger indexing paths, in which the spring 24 wanders over the forehead 26 of the switch, when the arm 16 returns, the spring 24 is deflected by the flank 26 to the flank 29, so it cannot operate the switch 3o when the switch is returned.

In order to be able to set the individual receiving relays to different remote control files, the switch 30 and the t, @ 'calibration part z5 can be attached in an adjustable manner. So that one and the same relay can execute several remote control files, several switches and switch parts can be arranged at certain distances from one another.

In Fig. 1, the guide piece 25 and the switch 30 stop, while the part 24 evades. But you can also make the arrangement so that the part 24 or the arm tci is rigid and displaces the movably arranged, connected to the switch 30 switch part 25 such that the switch 30 is only actuated when the arm moves a certain distance.

Another embodiment for the control element and the control part shows FIG. 2. Here, a pawl 24 is attached to the end of the control arm 16. The switch 3o is on a support 32 which can pivot about the axis 31 and has a latch spring 33 attached. The spring 34 seeks to urge the carrier 32 against the stop 35 and thereby bringing the switch 30 into the stepping path of the pawl 24.

The mode of operation is similar to that of FIG. 1. When the arm 16 moves forward, there is no circuit. because the latch 2- ;. both your switch 3o and the pawl 33 evade if the arm 16 is switched forward beyond the part 33. When the arm 16 returns, the carrier 32 is locked into the position shown by means of the pawl 24. in which the switch 3o is no longer in the way of the pawl-24. Only when the pawl 24 has wandered past does the carrier 32 swing back to the stop 35. The switch 30 can no longer be reached by the pawl 24. If, however, the switching path of the part 16 is controlled by a corresponding number of pulses so that at the end of the broadcast the pawl a4 is just between your switch 30 and the pawl 33, then when the arm 16 returns, the switch 3o is through the pawl? 4 closed. In the case of smaller incremental paths, the pawl 24 does not reach the switch 30 at all.

In Fig. 3, a member 24o is hinged to the Schaltann 16, which after both Directions can be pivoted. The spring 36 seeks the member 24o in the extended position to urge. A finger 2: I1 of the link 24o runs on a guide part in the shape of a circular arc 37 with recesses 38 to 40. The recess 38 is located near the start stop 23, the recess 39 is arranged at the switch 30, the recess d.o. is located in the area of larger incremental paths.

The device works in such a way that, when shifting forward, the element 24o assumes the position shown and, if it does not reach the recess 39, it also runs back in the position shown. If the switch 3o is to be actuated, the arm 16 is switched forward so far that the finger 2d 1 reaches the recess 39 or a little further, but not quite to the recess 4o. When the arm 16 returns, the finger 241 moves in the radial direction into the recess 39, the parts 16 and 240 move into the extended position in which the part 2.Io closes the switch 30 . With further return, the arm 16 grinds the part 24o. Only in the starting position at the stop 23 and the recess 38 do the two parts return to their extended position.

In the case of larger indexing paths of the arm 16, the finger 241 moves up to or beyond the recess 4o; when the arm 16 returns, the parts 16 and 24o reach the recess 4o in the extended position. From then on, the arm 1C grinds; the part 24o and grinds it over the recess 39 without the two parts again reaching the extended position; the switch 30 is therefore not actuated in this case.

The resonance relay 3 can also be a voltage drop relay be replaced. The control impulses are then switched off briefly and repeatedly or lowering of the mains voltage.
