Description

Receiver for remote control through time-coded pulses with a timer for pulse selection The invention relates to that type of remote control system with any control channels, i.e. those with time-coded control pulses is being worked on. The recipients of such: systems are equipped with timers for pulse selection equipped. In the simplest case, a remote control act takes place in such a way that through an initial pulse at the beginning of a control period receiving relay the timer Activate the receiver. These timings prepare for a certain point in time, which differs from remote control act to remote control act, provide an enforcement circle. At the end of the tax period, the timer automatically stop and bring the receiver back to its original state. Depending on the time in which within a control period a second pulse, the completion pulse, is sent one or the other relay on or one or the other remote control act is carried out.

When testing the profitability of remote control systems, The choice of the type of remote control often depends on the number of relays to be remotely controlled. If many relays are required, the type of remote control that has been preferred so far is the cheapest recipient results. -One has for example with different frequencies remotely controlled, because then the receiver is only tuned to one or a few frequencies to become »smoke and not an expensive one Need Zeitwerk. The number the remote control file is then limited because there are usually not enough frequencies be available. A remote control with time-encrypted pulses, on the other hand results in a significantly larger number of remote control files. Also need to the transmission channels not to be made so high demands, since one with a single, conveniently located control frequency gets by. In return, however, the effort for the numerous, equipped with timers Relay so large that, despite the technical advantages, such a type of remote control in the case of a large number of recipients for economic reasons.

The invention allows the effort in the last-mentioned type of remote control to be reduced considerably for the recipients, so that - now also with a larger number of recipients a remote control system that works with time-encrypted pulses is economical is.

According to the invention, a liquid timer is used as a timer for the receiver used. These are mostly mercury switches, which after tilting the Mercury, like an hourglass, moves from a higher to a lower one @ The vessel part flows slowly and, depending on the liquid level, contacts of the switch closes or opens. If you want to avoid tilting the vessel, then you can the mercury column, in whose path the contacts are arranged, also by heating move a gas balloon. Tilting is here by switching the .der on and off Replaced heating.

The invention is illustrated by the examples shown in the drawing explained in more detail.

A receiving relay is connected to a remote control channel of a remote control line io (Fig. i) connected. The nature of this relay and its type of connection is not the subject of the invention. The relay is operated with a make contact switch n and 14. The switch is located with a magnet 16 for toggling on, e-s mercury time switch 2 i in series on a power network N. The contacts are parallel to switch 14 18, 2o of this timer. 2i1.

With the completion switch i i are a, preparation switch 12 with Working contact, the remotely controlled device 15 of the enforcement circuit i5o and the contacts ig, 2o of the timer in, row ges, o halted. The preparation switch 12 is actuated by a relay connected to contact 17 of the timer.

Fig. I shows the time switch zi in .der rest position when switched off Tilt magnet 16; Figure 3 shows at the top the same time switch in the working position with the magnet 16 switched on, i.e. after tilting.

The arrangement works as follows: The relay is calibrated in this way (this is done by arranging the contacts of the liquid switch accordingly) that, as shown in FIG. 2 on the right at E, the device 15 is only actuated when between the times o, i and 4, 5 pulses are given to the receiving relay io. The time span between times o and 8 is the transmission period. Naturally are, often within a transmission period, when various remote control acts are carried out should also be given remote control pulses at other times. These must but be ineffective for the relay at hand.

To make it easier to understand the working methods are wrong. 2, the individual switching clocks below the individual parts 2o of Fig. I plotted, at the switches i i, 12, 14 by a serrated line, at the liquid contacts 17 to 2o by thick lines for the case of the contact closure. With parts io, J3, 15, 16 thick lines indicate that they are carrying current.

Before the point in time o, all parts are in the one shown in FIG. Position. At this point in time the start impulse: is sent, the one up to the point in time i persists. During this time the relay io carries current, the switch il is closed, but remains ineffective because. the contact is open. The switch 14 closes and thereby switches the magnet 16 on. This tilts the timer in the direction of the arrow 21, which now: (see. Fig. 3) by bridging the contacts 18, 2o a self-holding for the magnet u6 '. At the same time, the contacts are now closed 17, 2o the relay 13 switched on, which closes the preparation switch 12.

At the beginning the mercury levels of the timer (Fig. 3 above) the position Ni, N1; so all contacts are submerged except for ig.

After the initial impulse has stopped, the switches open again i i and (14. These interruptions are ineffective because 16 self-retention Has.

A completion pulse is issued for any other recipient between times g, 3. Switches ii and 14 are temporarily closed without any effect. So. , the enforcement impulse that is decisive for the recipient at hand follows between times 4, 5. At time 4, the mercury 25 (FIG. 3) has reached the levels N4, N4 . The contact ig is closed and thereby prepares the full circuit i5o. When the completion pulse arrives, at which the switches 111, 14 are closed again, current flows from the network N via 12, 11, 15, ig, 2o to the network. The remote control act in 15 is therefore carried out. At the point in time 5, the contact 17 emerges from the mercury 25. As a result, the relay 13 is switched off and the switch 12 is opened. From this point onwards, the device 15 can no longer be actuated by further pulses within the transmission period, for example by a pulse between the points in time 6, 7, since the execution circuit 15o remains open by the switch 12.

At time 8, at the end of the period, the mercury leaves 25, the finally wants to adjust to the level Ne, N, contact 18 and interrupts thereby the self-holding of the magnet l16. The liquid switch 21 returns in the Position of Fig. I back, and thereby the initial state is again of the recipient.

The liquid switch consists in a known manner from an angled Tube 22, 23, the legs of which are connected by a narrower tube 24. The container can be tilted about axis 26. When the magnet 16 is switched off, the mercury flows 25 from the tube 23 into the vessel 22, instantly. After turning on of the magnet and tilting it up into the position shown in FIG. 3, the mercury flows slowly back out of the vessel 2 through the pipe 24 into the vessel 23.

The relay 12, 13 and the contacts 17, i9 on the vessel 21 can be used omit if a second, with the liquid switch 21 coupled liquid switch -io is used, which in turn has corresponding electrodes 170, 190. These Electrodes are connected to the completion switch i i and the remote-controlled device 15 in the full circuit fi5o switched on. This circle is only for the period of time between points 4, 5 (Fig. 2), because the electrode is igo beforehand and afterwards the electrode 17o is immersed. Otherwise the arrangement and mode of operation is unchanged the same as in Fig. i.

If you want to avoid a tiltable liquid switch, then you can one, as for example Fig. 4 shows, also a thermal liquid switch 211 use. It consists of a U-tube 212 with two balloons 213, 214, of which one of which contains a heating coil 215. The circuit is essentially the same as in Fig. i. The same reference symbols are used for the corresponding parts. The only new addition is the switch controlled by the relay 16 for on and off Switching off the heating resistor 215 and a special self-holding switch 16o for this relay, which is connected to grain clocks 18, 2o of the liquid timer in Row lies. The switch 16o is required after switching off the heating coil @ 15 the mercury 25 returning to the position shown does not go through Bridging the contacts 18, 2o switch on the magnet 16 again. can..

Here, too, the contacts 17, 19 can again be a special vessel be allocated, which only temporarily prepares the executive circle i5o. The circuit and arrangement for such receivers can be modified in many ways, e.g. B. also such that a first liquid timer, the switching operations up to Selection of the second remote control pulse and then the activation of one second liquid timer causes the then at the end of the control period restores the entire receiver to its initial state.

The embodiment shows a receiver that only has a single Switching act can perform. As a rule, the recipient will create two tax files, e.g. B. A and switching off a device, or even more control files z. B. with step control, carry out. The number of contacts of the liquid switch must then be appropriate increase.
