Description

Die Erfindung betrifft einen Fernschalter der im ersten Teil des Anspruchs 1 genannten Art.The invention relates to a remote switch of the type mentioned in the first part of claim 1.

Fernschalter, die mit einem der Netzwechselspannung überlagerten trägerfrequenten Fernsteuersignal ein- bzw. ausschaltbar sind, verwendet man insbesondere dort, wo eigene Steuerleitungen nicht verwendet werden können oder sollen. Fernschalter dieser Art können an einer beliebigen Stelle z.B. eines Hausinstallationsnetzes eingesetzt und von einer ebenso beliebigen anderen Stelle mit Hilfe eines Leitgerätes gesteuert werden.Remote switches that can be switched on or off with a carrier-frequency remote control signal superimposed on the mains AC voltage are used in particular where own control lines cannot or should not be used. Remote switches of this type can e.g. a house installation network and can be controlled from any other location with the help of a control unit.

Es ist bekannt, einen Fernschalter mit einer Empfangs- una Sieuereiektronik auszustatten, die das vom Netz kommende trägerfrequente Fernsteuersignal aufnimmt und eine elektromagnetisch betätigte Schaltstrecke steuert. Diese Fernschatter werden als Zwischenstecker zum Einsatz an Steckdosen, wie auch als Unterputzgeräte verwendet. Bisweilen ist es möglich, die Fernschalter sowohl von einer zentralen Leitstelle aus, als auch durch unmittelbar am Gerät angebrachte Schaltelemente zu betätigen.It is known to equip a remote switch with a reception and control electronics which receives the carrier-frequency remote control signal coming from the network and controls an electromagnetically actuated switching path. These remote shaders are used as intermediate plugs for use at sockets, as well as flush-mounted devices. Sometimes it is possible to operate the remote switch both from a central control center and by switching elements directly attached to the device.

Bei den bekannten Fernschaltern wird als Mangel empfunden, daß man sich zu ihrer Betätigung unmittelbar in ihrer Nähe oder im Bereich einer Leitstette befinden muß. Oft ist es erwünscht, den Fernschalter von ganz anderer Stelle aus zu betätigen, ohne daß man hier ein zusätzliches Leitgerät einsetzen möchte.In the known remote switches, it is felt as a defect that one has to be in the immediate vicinity of them or in the area of a control room to operate them. It is often desirable to operate the remote switch from a completely different location without using an additional control unit.

Aufgabe der Erfindung ist es, einen Fernschalter der im ersten Teil des Anspruchs 1 genannten Art zu schaffen, dessen Ein/Aus-Schaltfunktion nicht nur durch das trägerfrequente Steuersignal, sondern durch weitere Betätigungsmittel ausgelöst werden kann, um somit zusätzliche Anwendungsmöglichkeiten zu schaffen.The object of the invention is to provide a remote switch of the type mentioned in the first part of claim 1, the on / off switching function of which can be triggered not only by the carrier-frequency control signal but also by further actuating means, in order to create additional possible uses.

Diese Aufgabe wird durch die im Anspruch 1 gekennzeichneten Merkmale gelöst.This object is achieved by the features characterized in claim 1.

Von besonderem Vorteil ist, daß die zusätzlichen Betätigungsmittel, mit denen der Fernschalter ausgerüstet ist, keinen nennenswerten Zusatzaufwand erfordern. So genügt es am Fernschalter ein festinstalliertes oder lose verlegtes zweiadriges Elektrokabel anzuschließen, dessen beide Enden je nach Anschlußelement mit einem monostabilen Taster oder einem bistabilen Schalter zu überbrücken sind. Mit dem Taster wirkt der Fernschalter als Stromstoßrelais, wie es z.B. bei Treppenhausschaltern zur Anwendung kommt. Der bistabile Schalter ermöglicht eine Fernbedienung des Fernschalters ohne Leitgerät, kann aber auch durch einen Sensor ersetzt werden und wirkt dann in Verbindung mit dem Fernschalter z.B. als Helligkeitswächter, Leistungswächter oder Niveauschalter. Der von Hand zu bedienende Steuerschalter geht in seiner Wirkungsweise über bekannte Handschaltelemente hinaus, da er den Steuersignalen übergeordnet ist und ihren Einfluß in der Stellung "Aus" sperren und in der Stellung "Auto" freigeben kann.It is particularly advantageous that the additional actuating means with which the remote switch is equipped do not require any significant additional effort. It is therefore sufficient to connect a permanently installed or loosely installed two-wire electrical cable to the remote switch, both ends of which can be bridged with a monostable button or a bistable switch, depending on the connection element. With the button, the remote switch acts as a surge relay, e.g. is used for stairwell switches. The bistable switch enables remote control of the remote switch without a control device, but can also be replaced by a sensor and then works in conjunction with the remote switch e.g. as brightness monitor, power monitor or level switch. The mode of operation of the control switch to be operated by hand goes beyond known manual switching elements, since it is superior to the control signals and can block their influence in the "off" position and release it in the "auto" position.

Aufgrund seiner vielseitigen Anwendungsmöglichkeiten ist es zweckmäßig, den Fernschalter an zentraler Stelle z.B. im Hausanschlußkasten anzubringen und dementsprechend mit einem Reiheneinbaugehäuse zu versehen. Besonders in diesem aber auch in anderen Fällen kann es zweckmäßig sein, wenn der Fernschalter als weitere Schaltfunktion, die eines Sicherungsschalters übernimmt. Die hierzu erforderlichen Anpassungen des Schalteraufbaus sind relativ geringfügig. Mit einem geeigneten Signalgeber können ganz bestimmte Stromkreise überwacht werden und zwar je nach Bedarf auf Überstrom- und/oder Fehlerstromverhalten.Due to its versatile application options, it is advisable to position the remote switch at a central location e.g. To be installed in the house connection box and to be provided accordingly with a modular installation housing. Especially in this but also in other cases, it can be useful if the remote switch takes over as a further switching function that a fuse switch. The adjustments to the switch structure required for this are relatively minor. With a suitable signal transmitter, very specific circuits can be monitored, depending on the need for overcurrent and / or residual current behavior.

Weitere, insbesondere den mechanischen Aufbau des Fernschalters betreffende Ausgestaltungen und Fortbildungen des Erfindundsgegenstandes, sind in den abhängigen Ansprüchen genannt.Further, in particular the mechanical structure of the remote switch related refinements and developments of the subject matter of the invention are mentioned in the dependent claims.

Ausführungsbeispiele der Erfindung sind in den Zeichnungen dargestellt und werden im folgenden näher beschrieben.Embodiments of the invention are shown in the drawings and are described in more detail below.

Wie insbesondere aus Fig. 2 ersichtlich, ist der beispielhaft gewählte Fernschalter mit einem Reiheneinbaugehäuse ausgestattet. Die Figuren 1 und 6 ermöglichen einen Blick auf das Gehäuse 1 mit der Gehäuseoberseite 1 a. Bei dem dargestellten Fernschalter handelt es sich um einen Einphasenschalter. Dieser besitzt fünf Anschlußelemente 5,6,7,8a, 8b, die als Schraubklemmen ausgeführt sind. Die zu steuernde Schaltstrecke liegt zwischen den Anschlußelementen 8a und 8b. Wird die Schaltstrecke geschlossen, so ist die Lampe 25 eingeschaltet, da sie nunmehr zwischen Phase und Null liegt. Sowohl die Stromversorgung des Fernschalters, insbesondere seiner Elektronik, wie auch die Zuführung des trägerfrequenten Steuersignals, erfolgt über die Anschlußelemente 6 und 8a. Die als Drehschalter ausgebildeten Codierschalter 2,3 dienen zur Wahl eines Empfangscodes derart, daß der Fernschalter nur auf ganz bestimmte trägerfrequente Fernsteuersignale anspricht.As can be seen in particular from FIG. 2, the remote switch selected by way of example is equipped with a modular installation housing. Figures 1 and 6 allow a view of the housing 1 with the housing top 1 a. The remote switch shown is a single-phase switch. This has five connection elements 5,6,7,8a, 8b, which are designed as screw terminals. The switching path to be controlled lies between the connection elements 8a and 8b. If the switching path is closed, the lamp 25 is switched on since it is now between phase and zero. Both the power supply of the remote switch, in particular its electronics, as well as the supply of the carrier-frequency control signal takes place via the connection elements 6 and 8a. The coding switches 2, 3 designed as rotary switches are used to select a reception code such that the remote switch responds only to very specific carrier-frequency remote control signals.

Mit Hilfe eines an Phase liegenden Tasters 23 ist es ebenfalls möglich über das Anschlußelement 5 den Fernschalter abwechselnd ein- und auszuschalten. Der durch die monostabile Schaltfunktion des Tasters 23 erzeugte Spannungsimpuls von 220 V bewirkt das Umschalten. Der Femschalter wirkt hierbei im Prinzip wie ein Stromstoßrelais, d.h. in Verbindung mit dem Taster 23 kann er zum Schalten einer Treppenhausbeleuchtung verwendet werden.With the aid of a button 23 in phase, it is also possible to switch the remote switch on and off alternately via the connecting element 5. The one through the monostable switching function of the button 23 generated voltage pulse of 220 V causes switching. In principle, the remote switch acts like a surge relay, ie in conjunction with the button 23 it can be used to switch stairwell lighting.

Anstelle eines ständigen Wechsels des Schaltzustandes, wie ihn die an Anschlußelement 5 anliegenden Spannungsimpulse bewirken, wird häufig ein definiertes Ein/Aus-Schaltverhalten gefordert. Dieser Forderung wird durch das Anschlußelement 7 Rechnung getragen. Der Fernschalter ist so lange eingeschaltet, solange an dem Anschlußelement 7 eine Spannung von 220 V anliegt. Im

Figure imgb0001
Fall wird hier ein normaler bistabiler Schalter 24 eingesetzt, an dessen Stelle auch ein Sensor treten kann, der in Abhängigkeit von einem Grenzwert z.B. der Helligkeit, der Leistung oder des Niveaus ein Ein/Aus-Schaltverhalten bewirkt.Instead of a constant change in the switching state, as caused by the voltage pulses applied to connection element 5, a defined on / off switching behavior is often required. This requirement is met by the connection element 7. The remote switch is switched on as long as there is a voltage of 220 V at the connecting element 7. in the
Figure imgb0001
In this case, a normal bistable switch 24 is used, which can be replaced by a sensor which, depending on a limit value, for example the brightness, the power or the level, causes an on / off switching behavior.

Wesentlich ist die Funktion eines auf der Gehäuseoberseite 1a angeordneter Steuerschalters 4, der als Schiebeschalter ausgeführt ist. Dieser Steuerschalter 4 ermöglicht es, alle übrigen Schaltbefehle, die über die Anschlußelemente dem Fernschalter zugeführt werden, außer Kraft zu setzen. Das heißt in den beiden Schaltstellungen "Ein" (1) und "Aus" (0) bleiben die externen Steuersignale ohne Einfluß. Allein in der Schaltstellung "Auto" ermöglicht der Steuerschalter 4 die externe Steuerung des Fernschalters.What is essential is the function of a control switch 4 arranged on the top of the housing 1a, which is designed as a slide switch. This control switch 4 makes it possible to override all other switching commands which are supplied to the remote switch via the connection elements. This means that in the two switch positions "On" (1) and "Off" (0) the external control signals have no influence. In the "Auto" switch position alone, the control switch 4 enables external control of the remote switch.

Besonders bei solchen Fernschattern, die als Reiheneinbaugeräte gestaltet sind und sich somit zur Installation in Zählertafeln und Verteilungen eignen, ist es zweckmäßig, auch eine Sicherungsabschaltung vorzunehmen. In diesem Fall, der in den Zeichnungen nicht dargestellt ist, wird ein Signalgeber in den zu überwachenden Stromkreis geschaltet. Bei fehlerhaftem Strom, z.B. Überstrom, gibt der Signalgeber ein Steuersignal ab, das dem Fernschalter zugeführt wird und diesen zur Abschaltung bringt. Bei einem in der Nähe des Fernschalters angeordneten Signalgeber kann die Übertragung des Abschaltsignals durch eine direkte Verbindung mit einem weiteren Anschlußelement erfolgen. Es ist aber auch möglich, das Abschaltsignal des Signalgebers als trägerfrequentes Fernsteuersignal zu übertragen.Especially with such remote switches, which are designed as modular devices and are therefore suitable for installation in meter panels and distributors, it is advisable to also switch off the fuse. In this case, which is not shown in the drawings, a signal generator is connected to the circuit to be monitored. With faulty current, e.g. Overcurrent, the signal generator emits a control signal which is fed to the remote switch and switches it off. In the case of a signal transmitter arranged in the vicinity of the remote switch, the switch-off signal can be transmitted by a direct connection to a further connection element. However, it is also possible to transmit the switch-off signal of the signal transmitter as a carrier-frequency remote control signal.

Von besonderer Bedeutung ist, gerade auch, wenn der Fernschalter als Sicherungsschalter verwendet werden soll, daß er durch ein bestimmtes Steuersignal in einen definierten Schaltzustand versetzt werden kann. Wie Fig. 5 erkennen läßt, besitzt der elektromagnetische Schalter 11 zwei Erregerwicklungen 12,13, die beide auf einen Magnetanker 14 wirken. Wird der Erregerwicklung 12 ein Strom zugeführt, so zieht sie den Magnetanker 14 auf ihre Seite und bewirkt über einen Kipphebelmechanismus, daß der Schaltkontakt 15 den Schalter schließt. Andererseits wird über die Erregerwicklung 13 der Schalter eindeutig geöffnet. Die den Erregerwicklungen 12,13 vorgeschaltete Elektronik sorgt dafür, daß die dem jeweiligen Steuersignal entsprechende richtige Erregerwicklung mit Strom versorgt wird.It is particularly important, especially when the remote switch is to be used as a safety switch, that it can be set to a defined switching state by a specific control signal. 5 shows, the electromagnetic switch 11 has two excitation windings 12, 13, both of which act on a magnet armature 14. If the excitation winding 12 is supplied with a current, it pulls the magnet armature 14 to its side and, via a rocker arm mechanism, causes the switch contact 15 to close the switch. On the other hand, the switch is clearly opened via the field winding 13. The electronics upstream of the excitation windings 12, 13 ensure that the correct excitation winding corresponding to the respective control signal is supplied with current.

Bei einem als Sicherungsschalter wirkenden Fernschalter muß die Sicherungsfunktion vor allen übrigen Schaltfunktionen, auch dem unmittelbar am Gerät angebrachten Steuerschalter, Vorrang erhalten. Zumindest muß verhindert werden, daß bei einer durch den Signalgeber bewirkten Abschaltung, der Fernschalter von anderer Seite wieder einschaltbar ist, obwohl der Fehlerfall nicht beseitigt wurde. Nachdem also das Abschaltsignal unmittelbar oder über vorgeschaltete elektronische Bauelemente der Erregerwicklung 13 des elektromagnetischen Schalters zugeführt wurde, die den Fernschalter in den definierten Schaltzustand "Aus" versetzt, muß eine Wiedereinschaltsperre dafür sorgen, daß der Fernschalter solange nicht wieder einschaltbar ist, bis ein Freigabesignal die Wiedereinschaltsperre löst.In the case of a remote switch acting as a safety switch, the safety function must have priority over all other switching functions, including the control switch directly attached to the device. At least it must be prevented that the remote switch can be switched on again from another side in the event of a switch-off caused by the signal transmitter, although the fault has not been eliminated. After the switch-off signal has been fed directly or via upstream electronic components to the field winding 13 of the electromagnetic switch, which puts the remote switch in the defined switching state "off", a restart lock must ensure that the remote switch cannot be switched on again until a release signal Restart lock releases.

Wie in Fig. 3 dargestellt, sind im Reiheneinbaugehäuse des Fernschalters Anschlußkammern 26 vorgesehen, die zur Aufnahme der als Schraubklemmen ausgeführten Anschlußelemente 5 bis 8 dienen. Zwischen dem Gehäusemittelteil 28 und den Anschlußkammern 26 sind je zwei Trennkammern 27 angeordnet, die für ausreichende Kriech- und Luftstrecken sorgen, um die elektrische Sicherheit zu gewährleisten. Die als Drehschalter ausgeführten Codierschalter 2, besitzen Schalträder 18, die einerseits in Lagerlöchern 19 der Gehäuseoberseite 1 und andererseits in Lagerlöchern einer parallel dazu angeordneten Leiterplatte eingepaßt sind. Auf der Leiterplatte, die in den Zeichnungen nicht dargestellt ist, befinden sich auch die Leiterbahnen, mit denen die Schleifkontakte 21 der Codierschalter 2, 3 in Verbindung stehen. Die gewählte Schaltstellung der Codierschalter 2, 3 wird durch ein Rastelement 29 fixiert, das in die am Umfang der Schalträder 18 ausgebildeten Zahnkränze eingreift. Der als Schiebeschalter ausgebildete SteuerschaGehäuseoberseite la befestigt und wird durch an der Gehäuseinnenseite ausgebildete Rastnocken 30 in seiner Schaltstellung gehalten.As shown in Fig. 3, connection chambers 26 are provided in the in-line housing of the remote switch, which serve to receive the connection elements 5 to 8 designed as screw terminals. Two separating chambers 27 are arranged between the middle housing part 28 and the connecting chambers 26, which ensure sufficient creepage distances and clearances to ensure electrical safety. The coding switches 2, designed as rotary switches, have switching wheels 18, which are fitted on the one hand in bearing holes 19 of the upper side 1 of the housing and on the other hand in bearing holes of a circuit board arranged in parallel therewith. On the circuit board, which is not shown in the drawings, there are also the conductor tracks with which the sliding contacts 21 of the coding switches 2, 3 are connected. The selected switching position of the coding switches 2, 3 is fixed by a latching element 29 which engages in the toothed rings formed on the circumference of the switching wheels 18. The control switch housing top la designed as a slide switch is fastened and is held in its switching position by locking cams 30 formed on the inside of the housing.

Eine Signallampe 16 dient zur Anzeige des jeweiligen Schaltzustandes. Ihre in der Zeichnung nicht dargestellte Fassung, die Schalträder 18 und ein Auflagezapfen 17, bestimmen den Abstand der Leiterplatte von der Gehäuseoberseite 1a. Eine Schraube, gegebenenfalls aber auch ein Rasthaken, ermöglichen es, die Leiterplatte am Auflagezapfen 17 zu befestigen.A signal lamp 16 serves to display the respective switching status. Your version, not shown in the drawing, the switching wheels 18 and a support pin 17 determine the distance of the circuit board from the top of the housing 1a. A screw, but possibly also a latching hook, make it possible to attach the circuit board to the support pin 17.

In den Trennwänden, die das Gehäusemittelteil 28 abgrenzen, sind Nuten 9a, 9b vorgesehen, die zur Aufnahme einer gegenüber der ersten, nicht dargestellten Leiterplatte, senkrecht angeordneten zweiten Leiterplatte 10 dienen. Daneben ist, durch Nocken an den Trennwänden geführt, der elektromagnetische Schalter 11 eingesetzt.Grooves 9a, 9b are provided in the partition walls, which delimit the middle part 28 of the housing, which are used to receive a second printed circuit board 10 which is arranged perpendicularly to the first printed circuit board, not shown. In addition, the electromagnetic switch 11 is inserted through cams on the partition walls.

Remote-control switch according to one of the preceding claims, characterised in that the housing (1) is provided with guide grooves (9a, 9b) in which a second printed circuit board (10) is arranged perpendicular to the first printed circuit board and, in parallel with this, the electromagnetic switch (11) which actuates the switching path.
5. Remote-control switch according to one of the preceding claims, characterised in that the electromagnetic switch (11) is equipped with two separate excitor windings (12, 13), in such a manner that an excitation current applied to one excitor winding (13) moves a switching contact (15) via the magnetic armature (14) into the distinct Off position and an excitation current supplied to the other excitor winding (12) moves the switching contact (15) into the distinct On position.
6. Remote-control switch according to one of the preceding claims, characterised in that at the top (1 a) of the housing, a signal lamp (16) is arranged which indicates the respective switching position "on" or "off" of the remote-control switch.
7. Remote-control switch according to one of the preceding claims, characterised in that the first printed circuit board is arranged to be parallel with the top (1 a) of the housing and the distance between the top (1a) of the housing and the printed circuit board is determined by at least one supporting peg (17), to which the printed circuit board is attached by means of a screw or a stop hook and by switching wheels (18) of the two coding switches (2, 3) which are constructed as rotary switches, in which arrangement the switching wheels (18) are provided on both sides with bearing pegs which engage in bearing holes (19) of the top (1 a) of the housing and of the first printed-circuit board.
8. Remote-control switch according to one of the preceding claims, characterised in that the connecting element (5), which is provided to be driven by On/Off voltage pulses, is connected to a monostable key switch (23) which is connected to phase (L) and that the connecting element (7) used for driving the remote-control switch with a stop signal is provided with a bistable switch (24) which is connected to phase (L).
9. Remote-control switch according to one of the preceding claims, characterised in that it interrupts (disconnects) the switching path as soon as it is reached by a disconnecting signal, supplied to it via carrier-frequency remote-control signals or via at least one further connecting element, of signal generator which is located in a circuit to be monitored and generates a disconnecting signal if the current is faulty.
10. Remote-control switch according to one of the preceding claims, characterised in that the disconnecting signal is supplied directly or via preceding electronic components (20) to the excitor winding (13) of the electromagnetic switch (11) which places the remote control switch into the specific "Off" condition of switching and that a reconnection lockout device has the function of preventing the remote-control switch from being reconnectable until the reconnection lockout device is released by a release signal.
