Abstract

The subject matter of the invention is a contactless switch comprising a light transmitter, a light receiver and a switching element which is controlled by the light receiver and which can switch at least one load on and/or off. The light transmission path between the light transmitter and the light receiver is influenced by objects. The switch which can be switched by a remote control transmitter is provided with a variable coding. The remote control transmitter contains a key panel coding. The command can be transmitted optionally by infrared beam or ultrasonics.

Description

BERUHRUNGSLOSER SCHALTER NON-CONTACT SWITCH

(Zusatz zu P 30 40 751.3) Die Erfindung betrifft einen berührungslosen Schalter mit einem Lichtsender, einem Lichtempfänger und einem von dem Lichtempfänger gesteuerten Schaltorgan, das einen Verbraucher in Abhängigkeit von einer Beeinflussung der Lichtübertragungsstrecke zwischen dem Lichtsender und dem Lichtempfänger durch Gegenstände ein- und / oder ausschaltet, nach dem Hauptpatent (Patentanmeldung P 30 40 751.3). (Addition to P 30 40 751.3) The invention relates to a non-contact Switch with a light transmitter, a light receiver and one of the light receivers controlled switching device, which a consumer depending on an influence the light transmission path between the light transmitter and the light receiver Switches objects on and / or off, according to the main patent (patent application P 30 40 751.3).

Ausgehend von den wesentlichen Merkmalen des Hauptpatentes, daß der Lichtsender ein impulsförmiges Licht aussendet und der Lichtempfänger ein lichtempfindliches Element und eine diesem nachgeschaltete Schaltstufe aufweist, die aufgrund eines empfangenen Lichtimpulses kurzer Zeitdauer fUr eine längere Zeitdauer durchschaltbar ist und die Schaltstufe einen bistabilen Multivibrator (FF) enthalt, der nach dem Empfang von mindestens einem Lichtimpuls umschaltbar ist, ist es Aufgabe der Erfindung, einen berUhrungslosen Schalter der eingangs beschriebenen Art zu verbessern und einem größeren Anwendungsbereich zugänglich zu machen. Ferner soll ein gewisses Sicherheitsbedürfnis bei der Bedienung des Schalters befriedigt werden.Based on the essential features of the main patent that the The light transmitter emits a pulsed light and the light receiver emits a light-sensitive light Element and this has a switching stage downstream, which due to a received light pulse of short duration for a longer period of time is and the switching stage contains a bistable multivibrator (FF), which after the Reception of at least one light pulse is switchable, it is the object of the invention to improve a contactless switch of the type described above and to make it accessible to a wider area of application. Furthermore, a certain Need for security when operating the switch can be satisfied.

Diese Aufgaben werden erfindungsganaß dadurch gelöst, daß der beruhrung lose Schalter mit einer Codierung versehen und durch einen codierten Fernbedienungsgeber schaltbar ist. Der Vorteil dieses erfindungsgemäßen Schalters liegt insbesondere darin, daß er einen Code beinhaltet und nur einen Sendeimpuls mit dem gleichen Code ein- und/oder ausgeschaltet werden kann.These objects are achieved according to the invention in that the contact loose switches provided with a coding and by a coded remote control transmitter is switchable. The advantage of this switch according to the invention is in particular in that it contains a code and only a transmission pulse with the same code can be switched on and / or off.

Dies bedeutet zundchst, doß der Schalter nicht ohne weiteres von Jedermann willkürlich und unberechtigt bedient werden kann. Durch die Fernbedienung erhält der Schalter den Vorteil, doß er aus jeder Position des Raumes bis zu einer Entfernung von bis zu rund 50 Metern geschaltet werden kann.First of all, this means that the switch should not be used by everyone can be operated arbitrarily and without authorization. Received by the remote control the switch has the advantage of being able to do it from any position in the room up to a distance can be switched from up to around 50 meters.

Wenn innerhalb eines Raumes oder eines Gebäudes eine Vielzahl von berührungslosen Schaltern installiert sind, die zudem nicht alle gleichzeitig geschaltet werden sollen und voneinander unabhängig sind, so kann in vorteilhafter Weiterbildung der Erfindung der Schalter mit einer veränderbaren Codierung versehen sein. Das bedeutet, daß von mehreren Schaltern einer oder eine Gruppe durch von außen bedienbare Elemente unterschiedlich codiert werden. Der Fernbedienungsgeber mit einer Tastenfeldcodierschaltung ermöglicht durch die Bedienung der Vielzahl von Tastenknßpfen die Aussendung der unterschiedlich codierten Impulse und damit das Schalten der berührungslosen Schalter unabhängig voneinander und ohne gegenseitige Störung. Die Befehlsubertragung vom Fernbedionungsgeber zum Empfangsbaustein im berührungslosen Schalter kann dobei durch Infrarotlicht oder durch Ultraschall erfolgen.If within a room or building a multitude of Contactless switches are installed, which also not all switched at the same time should be and are independent of each other, so can in an advantageous development the invention of the switch can be provided with a variable coding. That means that one or a group of several switches can be operated from the outside Elements are coded differently. The remote control transmitter with a keypad coding circuit enables the transmission of the differently coded pulses and thus the switching of the non-contact switches independently of each other and without mutual interference. The command subtransmission from Remote control transmitter to the receiving module in the contactless switch can be included be done by infrared light or by ultrasound.

Die Codierung kann nach den bekannten Systemen, beispielsweise Puls-Code-Modulation oder Frequenz-Modulation vorgenommen werden.The coding can be done according to the known systems, for example pulse code modulation or frequency modulation.
