Description

Ripple control receiver for network remote control according to the pulse selection process In known ripple control receivers for network remote control according to the pulse selection method the selection of the command impulses is carried out by the fact that cam wheels are synchronized with the encoder rotate, operate the fixed contacts. The setting of the Receiver on certain command by having the cam wheels opposite the start position twisted and locked in certain positions.

Because the cam wheels because of the limited space that is usually given are relatively small, the contacts can only have a low angular accuracy be operated. Checking whether an impulse is in the range specified for a command Time arrives, takes place through additional test disks, which with a multiple of the Run around Nessken Speed.

It is also already known how to avoid these disadvantages Such ripple control receivers occur, the individual command pulses individual segments arranged in a circle and designed in the manner of a printed so-on position to be assigned to the rotating synchronously with a control switching arm of the transmitter Grinding arms with top trap arranged concentrically to the arrangement of the segments Kind of printed circuit formed Sonleifbahnen connected and through certain Command pulses assigned to time slots are selected. Because printed circuits can be produced with a very high degree of accuracy and bottom contacts can have a far greater switching accuracy than nook contacts with these Arrangements on a rapidly circulating additional. soh.ibe are waived.

If it is desired to set the individual commands separately, then in these known arrangements on the rotating disk, adjustable segments to be provided or the individual panes must be exchanged for other panes will. This replacement or this setting of adjustable segments requires However, significant interference in the respective receiving device, with undesirable Adjustments of the contacts or damage to the device itself can occur.

The invention that of a ripple control receiver for network remote control according to the pulse selection method, in which the command pulses are individual circular arranged, designed in the manner of a printed circuit segments assigned are, auageht, with the rotating synohron with a control arm of the transmitter Grinding arms with concentric to the arrangement of the segments, also after Type of printed circuit boards and connected by specific time slots assigned command pulses are selected, these disadvantages are avoided by that each of the all possible time slots of the individual command pulses is assigned Segments with the help of conductor tracks to each one plug connection of the printed circuit board is connected and the one provided for receiving the various commands Receiving organs Wahlwelse can be connected to one or more of these plug connections are.

The individual segments are expedient with metallic tracks on the edge of a printed so holding plate anordinate Steoklamellen connected, which in turn via appropriately trained socket stokers to the individual Receiving relays assigned to command pulses can be connected In the drawing shows an embodiment of the invention.

A printed circuit board 1 carries four concentrically around a center point 0 arranged sliding tracks that are broken by sliding contact bridges 2 and 3. The sliding contact bridges 2 and 3 are driven by a synchronous motor 4, the structural design and attachment of which is not shown. the outer of the four sliding tracks consists of narrow segments 5, the distance between them the momentary pulse pattern is adapted. These segments 5 are on conductive webs led to lamellae 30 to 66 on the upper edge of the plate 1, where they are through contact sockets 23, 24a or 24b can be tapped. By inserting the sockets 23 The respective preselection command is determined via one of the slats 30 to 49, during the time slot of the respective execution command through the sockets 24a and 24b is recorded. These double-pole sockets lead over differently Polarized diodes for the execution relays 25 and 26, which are used as remanence relays or latching relays are formed and switched on via the diodes 91 and 93 and the diodes 92 or 94 can be switched off again.

The next inner sliding track on the plate 1 has only two Segments 6 and 7 for the starting process, while the two inner tracks 95 and 96 represent full rings and thus for the Stroni feed to the sliding contact bridges 2 and 3 serve.

The incoming audio frequency command pulses are recorded through the relay 8, which actuates a reversing contact 81 and a rest contact 82.

In the initial state, in which it is also used as a remanence relay trained Switching element 20 is energized, the sliding contact bridge 2 lies with its outer wiper end on the starting segment 11, so that the capacitor 12 is short-circuited via the resistor 13 is. As a result, the cascade amplifier 14 with two transistors is of a known design locked for the Motoreinsohalterelais 15, so that this relay 15 is not energized will. If a tone-frequency start impulse arrives via the Ltg line, that speaks Pulse relay 8 on. The contact 81 interrupts the short circuit for the capacitor 12, so that it is charged via the resistor 16. After a certain defined charging time of 400 ms, for example, is the voltage across the capacitor 12 so increased that the cascade amplifier 14 is permeable in its control path and thus the relay 15 responds. If the start impulse does not have the usual one Minimum length of 400 me, for example, closes before it is fully charged of the capacitor 12 of the contact 81 the capacitor again briefly, so that the relay 15 does not respond.

The task of the delay element with the resistor 16 and the Capacitor 12 is used to render short interference pulses harmless, caused by other Switching operations can get on the line Ltg.

However, if the start impulse is longer than 400 ms, the relay speaks 15 and switches the Synohronmotor 4 through the contact 151 for port movement of the Sole bridges 2 and 3. As a result, the slip bridge 2 leaves the start segment 11, but remains ineffective doohunäohst because of the sole bridge 2 at the beginning of the Rotary movement no further segment of the segment row 5 is swept. JedoohQ leads now the outer sole contact of the sole bridges 3 on the wider segment 7 and thus prepares the further test of the start command. It is for relief this process assumed that the valid for the recipient The start command has a length of 1200 m because it is already 400 ms due to the response delay the cascade circuit 14 have been consumed, the length of the segment 7 corresponds after a switching time of 800 ins, the start pulse is too short and thus ends within the time in which the sliding bridge 3 rests on the segment 7, then over the Contact 82, which closes again when the relay 8 drops out, an alternating voltage Q via the bridge 3, the diode 18 and a resistor 19 to the test relay 20 placed. As already mentioned, this relay 20 is designed as a remanence relay, This is due to earlier switching operations, for example by crossing over segment 6 for a short time was switched on before the end of a cycle and thus via its contact 201 has set the synchronous motor to forward running. The relay now becomes 20 by the polarity of the diode 18 and by the weaker current due to the resistance 19 de-energized and brought to rest. The Synehron motor is activated by flipping it of contact 201 is switched to reverse. The sole contact 3 runs backwards beyond the zero position until it encounters segment 6.

Any incoming command pulses are in this state ineffective because the cascade hold 14 is short-circuited by contact 202, so that the motor relay 15 remains switched on.

After reaching the segment 6 through the grinding bridge 3 receives the relay 20 through the diode 21 again voltage, so responds and switches the Synchronous motor 4 to run forward. The motor reverses its direction and runs clockwise until the sliding contact bridge 2 the segment 11 of the segment row 5 reached and thus the capacitor 12 Kurzsohlossen. This is the cascade maintenance 14th locked again and the relay 15 comes to waste and sets the engine shut down. So there will always be an exact starting position, even when entering reached by glitches, so that any idle or backlash angles are switched off are.

If the command pulse remains, the sliding contact bridge remains 3 runs over segment 7, the motor remains switched on and that Segment 7 is exited.

There now follows a check for command pulses that may have been too long through the sliding contact bridge 2. If this reaches segment 22, then, if the relay 8 is still energized, the relay 20 is again de-energized via the diode 18, so that the motor 4, as already shown, airs back into its zero position. Has the start command, however, is the correct lung, i.e. is when the segment is reached 22 the relay 8 has dropped out again, the engine continues to run.

The receiver shown is for receiving preselection and execution commands set up, i.e. the execution command is only executed if the Preselection command was given. The arrangement is now made so that the execution of a command is always carried out if a preselection pulse has not been received beforehand is. The preselection is selected through the socket 23 on the slats 30 to 49. If, for example, the Buchae 36 is plugged in, then the sliding bridge 2 may assigned segment reached, no impulse arrives. If an impulse would arrive, like that the relay 20 would be de-energized via the socket 23 via the contact 81, so that the motor is switched and runs back to its starting position. But there is no such preselection pulse when the lamella 36 is occupied by the sole bridge 2 a, eo the engine continues to run and thus reached the sliding contact the sockets 24a plugged into position 55 for the double command "on-off". Appears a command in one of the two positions, the execution relay. 25, the how already mentioned, a remanence relay is either switched on or off via contact 81. The motor then continues to run until it is in the zero position, i.e. / when it opens the segment 11, the capacitor 12 short-circuited and the motor relay 15 switched off will.

The receiver shown is for 10 double commands and 20 preselection commands, thus usable for a total of 200 double commands. Another multiplication is possible because start commands are given in different lengths. For this are only the start segments 7 by changing the pressure accordingly to widen or shrink.

By simply repositioning the sockets 23, 24a or 24b, the uniformly trained recipients at each deployment point for the corresponding Commands can be set. Any changes in the command type and command sequence can be installed on the spot by repositioning the sockets 23, 24a and 24b in a simple sterile manner be taken into account.
