Solche Schaltvorrichtung ist z.B. offenbart im Dokument WO 00/41274 .The present invention relates to an electronically controlled switching device with a remote control, via which one or more electrical consumers are separably connected to a fixed voltage source. In this way, the standby operation of electrical appliances is to be represented energy-neutral, ie in standby mode, the electrical appliances do not consume mains power. Such switching device is disclosed, for example, in the document WO 00/41274 ,

Durch den Standby-Betrieb von elektronischen Geräten können in einem Privathaushalt jährlich Stromkosten von über 100 Euro anfallen. Nach aktuellen Informationen des Umweltbundesamtes kostet der Standby-Betrieb von Elektrogeräten den Haushalten und Büros in Deutschland jährlich 3,5 Milliarden Euro.Due to the standby operation of electronic devices, a private household can incur electricity costs of more than 100 euros annually.

Aus der JP 06187868A ist eine solarbetriebene Fernbedienung zur Steuerung von Elektrogeräten bekannt. Gemäß Fig. 4 kann über die Fernbedienung Sa eine Schaltvorrichtung 21 zur Versorgung der Verbraucher 23, 23a betätigt werden. Mit der bekannten Vorrichtung kann zwar der Energieverbrauch der Fernbedienung, nicht jedoch der Energieverbrauch der Schaltvorrichtung im Standby-Betrieb vermieden werden.From the JP 06187868A is a solar powered remote control for controlling electrical appliances known. According to FIG. 4, a switching device 21 for supplying the consumers 23, 23a can be actuated via the remote control Sa. Although the energy consumption of the remote control, but not the energy consumption of the switching device in standby mode can be avoided with the known device.

Aufgabe der vorliegenden Erfindung ist es, eine Schaltvorrichtung der eingangs genannten Art derart weiter zu entwickeln, dass die Elektrogeräte - wie im Standby-Betrieb - jederzeit über eine Fernbedienung in Betrieb gesetzt werden können, jedoch dabei im ausgeschalteten Zustand keine Energie aus dem Festnetz - weder durch die Endverbraucher noch durch die Schaltvorrichtung - verbraucht wird.Object of the present invention is to develop a switching device of the type mentioned in such a way that the electrical appliances - as in standby mode - can always be put into operation via a remote control, but in the off state, no energy from the fixed network - neither is consumed by the end user through the switching device -.

Diese Aufgabe wird durch eine Vorrichtung gemäß Anspruch 1 gelöst. Sie besteht aus einer Schaltvorrichtung, welche zwischen einer Festspannungsquelle und einem Verbraucher angeordnet ist und nach Empfang von bestimmten Signalen den Kontakt zwischen Verbraucher und Festspannungsquelle herstellt oder diesen Kontakt unterbricht.This object is achieved by a device according to claim 1. It consists of a switching device which is arranged between a fixed voltage source and a consumer and, after receiving certain signals, establishes the contact between the consumer and the fixed voltage source or interrupts this contact.

Damit im ausgeschalteten Zustand weder Strom von der Festspannungsquelle durch den Verbraucher noch durch die Schaltvorrichtung fließt, enthält die Schaltvorrichtung vorzugsweise eine eigene Spannungsquelle zur Durchführung des Schaltvorgangs.Thus, in the off state, neither current flows from the fixed voltage source through the consumer nor by the switching device, the switching device preferably includes its own voltage source for performing the switching operation.

Bevorzugte Spannungsquellen sind Transformatoren, Solarzellen, Ladungsspeicher, insbesondere Akkumulatoren, Batterien, Thermoelemente oder Dynamos. All diese Spannungsquellen können selbstverständlich kombiniert werden.Preferred voltage sources are transformers, solar cells, charge storage devices, in particular accumulators, batteries, thermocouples or dynamos. Of course, all these voltage sources can be combined.

Besonders bevorzugte Kombinationen sind Solarzellen, welche mit Ladungsspeichern, insbesondere Kondensatoren oder Akkumulatoren verbunden sind und diese aufladen oder zumindest mit Energie versorgen. Die Ladungsspeicher wiederum versorgen bevorzugt die Schaltvorrichtung mit Energie.Particularly preferred combinations are solar cells which are connected to charge storages, in particular capacitors or accumulators, and charge or at least supply them with energy. The charge storage devices in turn preferably supply the switching device with energy.

Auf diese Weise wird ein netzunabhängiger Betrieb der Schaltvorrichtung (z.B. enthaltend einen Mikrocontroller und Transistoren oder Relais) realisiert.

Dazu muss die Strahlungs-Signal-Empfänger-Baugruppe so gestaltet sein, dass sie entweder das Signal einer solchen Fernsteuerung durch Abgleich von Referenzsignalen einer internen Datenbank erkennt, oder dass die Strahlungs-Signal-Empfänger-Baugruppe einen internen Speicher enthält und eine Elektronik, welche auf ein Speichersignal hin das letzte empfangene Signal als Schaltsignal zum Abgleich abspeichert, oder auf andere weise in der Lage ist, Signale von beliebigen Fernsteuerungen zu lernen. Die letztgenannten lernfähigen Strahlungs-Signal-Empfänger-Baugruppen sind dem Fachmann bekannt.For this purpose, the radiation signal receiver assembly must be designed so that it either detects the signal of such a remote control by adjusting reference signals of an internal database, or that the radiation signal receiver assembly includes an internal memory and electronics, which stored on a memory signal, the last received signal as a switching signal for adjustment, or in other ways, is able to learn signals from any remote controls. The latter learning radiation signal-receiver assemblies are known in the art.

Das mit der Schaltvorrichtung verbundene Solarmodul ist derart dimensioniert und gegebenenfalls mit einem Akkumulator gepuffert, dass der Betrieb der Schaltung jederzeit - auch bei schwachem umgebungslicht, Kunstlicht oder zeitweiliger Dunkelheit - gewährleistet ist.The solar module connected to the switching device is dimensioned and optionally buffered with an accumulator that the operation of the circuit at any time - even in low ambient light, artificial light or temporary darkness - is guaranteed.

Die Leistungsentnahmeeinheit ist bevorzugt mit einem Element der Gruppe bestehend aus Ladungsspeicher der Schaltvorrichtung, z.B. einem Kondensator oder Akkumulator und/oder einem elektronischen Schalter der Schaltvorrichtung, verbunden, wobei der Ladungsspeicher dabei aufgeladen oder zumindest mit Energie versorgt wird und der elektronische Schalter mit der nötigen Betriebsenergie versorgt wird und/oder durch die Leistungsentnahmeeinheit ein Signal erhält, welches dem Schaltsignal entspricht oder zumindest den elektronischen Schalter in den eingeschalteten Zustand versetzt.In a preferred embodiment, the switching device includes an electrically conductive connection leading to a power extraction unit and conductively connecting it to the switching device. The power extraction unit is preferably connected to an element of the group consisting of charge storage of the switching device, e.g. a capacitor or accumulator and / or an electronic switch of the switching device, wherein the charge storage is charged or at least supplied with energy and the electronic switch is supplied with the necessary operating energy and / or receives a signal through the power extraction unit, which corresponds to the switching signal or at least the electronic switch is set in the on state.

The assembly 1 is on the one hand to a fixed line voltage 4 and on the other hand to a consumer - here, for example, a TV set 5 - connected.

Die Schaltvorrichtung kann ein empfangenes Strahlungssignal - beispielsweise ein IR- oder Funksignal - aus einer Fernbedienung 6 in einen Schaltimpuls umwandeln. Dadurch wird ein Verbraucher bzw. das TV-Gerät 5 mit der Festnetzspannungsquelle 4 entweder verbunden oder von ihr getrennt.The switching device can convert a received radiation signal - for example an IR or radio signal - from a remote control 6 into a switching pulse.

Die Schaltvorrichtung sollte für den Betrieb einer Festnetzspannungsquelle von 100 - 280 Volt, 50 - 60 Hertz und bis zu 18 Ampere Stromaufnahme geeignet sein. Die Strahlungssignalempfängerbaugruppe 1 sollte dabei "selbstlernend" für den Empfang und die Verarbeitung handelsüblicher Fernbedienungen programmierbar sein. Hierzu gehört, dass sie ein empfangenes Signal bis zur nächsten Programmierung speichert. Für den Betrieb mehrerer Verbraucher ist die Programmierung / Speicherung auch von unterschiedlichen Geräten parallel möglich.The switching device should be suitable for the operation of a fixed voltage source of 100 - 280 volts, 50 - 60 hertz and up to 18 amps of current consumption.

Hierzu ist das TV-Gerät 10 permanent mit dem Stromnetz 11 verbunden und verursacht hierdurch einen Standby-Verbrauch von ca. 3 W. Mittels der handelsüblichen Fernbedienung 12 kann über den Standby-Empfänger 13 des TV-Gerätes 10 der Betrieb jederzeit aufgenommen bzw. beendet werden. Fig. 2 illustrates the circuit of a standby operation in conventional construction.
