Abstract
Description
Die Erfindung betrifft eine Schaltungsanordnung nach dem Oberbegriff des Patentanspruchs. Die Leistungsaufnahme von infrarot-fernbedienbaren Geräten, insbesondere Fernsehgeräte, beträgt im Stand-by-Betrieb ca. 3- 15 Watt.The invention relates to a circuit arrangement according to the Preamble of the claim. The power consumption of infrared remote-controlled devices, TVs, in stand-by mode is approx. 15 watts.
Schaltungskonzepte, welche die Leistungsaufnahme im Stand-by- Betrieb wesentlich senken können, sind in der DE-OS 31 37 081 bekannt geworden, bei der über Solarzellen eine wiederaufladbare Batterie gepuffert wird. Der Schaltungsaufwand und Kosten für diese Lösung sind relativ hoch. Mit der DE-OS 32 42 333, EP 01 67 737 A1 und EP 01 58 251 A1 sind Lösungen für einen stromsparenden Stand-by-Betrieb bekanntgeworden. Die Leistungsaufnahme dieser Lösungen im Stand-by-Betrieb ist bedingt durch die Verwendung eines Netztransformators nicht wesentlich verringert worden.Circuit concepts, which reduce the power consumption in the stand-by Can significantly reduce operation, are in DE-OS 31 37 081 became known in the solar cells via a rechargeable Battery is buffered. The circuit complexity and costs for this solution is relatively high. With DE-OS 32 42 333, EP 01 67 737 A1 and EP 01 58 251 A1 are Solutions for energy-efficient stand-by operation known. The power consumption of these solutions in stand-by mode is due to the use of a mains transformer not significantly reduced.
Der vorliegenden Erfindung lag die Aufgabe zugrunde, ein Schaltungskonzept zu entwickeln, das eine wesentlich reduzierte Leistungsaufnahme von ca. 100 mW bei minimalem Schaltungsaufwand im Stand-by-Betrieb ermöglicht.The present invention has the object, a To develop a circuit concept that significantly reduced Power consumption of approx. 100 mW with minimal circuit complexity in stand-by mode.
Die Aufgabe ist erfindungsgemäß nach der im Patentanspruch wiedergegebenen Lehre gelöst.The object is according to the invention in the claim solved doctrine solved.
Gemäß dem Schaltungskonzept wird im Stand-by-Betrieb nur der IR- Empfänger und Mikrorechner (2) mit Relais (1) mit einer Gleichspannung versorgt, die von einem Kondensator (3) als kapazitivem Vorwiderstand und einer Gleichrichteranordnung (6) mit Ladeelko (7) direkt aus der Netzspannung erzeugt wird. Beim Einschalten des Relais (1) wird über den Relaiskontakt (5) ein zweiter Kondensator (4) dem ersten Kondensator (3) parallelgeschaltet. Im Stand-by-Betrieb ist der Kondensator (3) als kapazitiver Widerstand und die Gleichrichterkombination (6) mit dem Ladeelko (7) so bemessen, daß die Betriebsspannungsversorgung des IR- Empfängers, des Mikrorechners und die Einschaltenergie des Relais gesichert ist, andererseits der Strom zum Halten des Relais nicht ausreicht. Damit ergibt sich im Stand-by-Betrieb eine Leistungsaufnahme je nach verwendeten IR-Empfänger, Mikrorechner und Relais von ca. 100 mW. Um den erforderlichen Strom zum Halten des Relais aufzubringen, wird erfindungsgemäß ein zweiter Kondensator (4) nach Schließen des Relaiskontaktes dem ersten Kondensator (3) parallelgeschaltet. Dabei ist kein separater Relaiskontakt notwendig, sondern der Kondensator kann über den Kontakt, mit dem der Verbraucher zugeschaltet wird, ebenfalls zugeschaltet werden. According to the circuit concept, in stand-by mode only the IR receiver and microcomputer ( 2 ) are supplied with relays ( 1 ) with a DC voltage which is supplied by a capacitor ( 3 ) as a capacitive series resistor and a rectifier arrangement ( 6 ) with charging capacitor ( 7 ) is generated directly from the mains voltage. When the relay ( 1 ) is switched on, a second capacitor ( 4 ) is connected in parallel to the first capacitor ( 3 ) via the relay contact ( 5 ). In stand-by mode, the capacitor ( 3 ) as a capacitive resistor and the rectifier combination ( 6 ) with the Ladeelko ( 7 ) so dimensioned that the operating voltage supply of the IR receiver, the microcomputer and the turn-on of the relay is secured, on the other hand Power to hold the relay is insufficient. This results in a stand-by power consumption depending on the used IR receiver, microcomputer and relays of about 100 mW. In order to apply the required current for holding the relay, according to the invention a second capacitor ( 4 ) is connected in parallel with the first capacitor ( 3 ) after closing the relay contact. In this case, no separate relay contact is necessary, but the capacitor can also be connected via the contact with which the consumer is switched.
Der Ladeelko (7) hat die Aufgabe, die Energie zum Einschalten des Relais zu liefern. Der Kondensator (4) ist so bemessen, daß der erhöhte Stromverbrauch der Relaiswicklung ausgeglichen wird. In Ausgestaltung der Schaltung kann z. B. ein Optokoppler zur Weiterleitung der Befehle an den Hauptrechner eingesetzt werden. Weiterhin ist über einen Optokoppler eine Rückführung von Befehlen vom Hauptrechner, z. B. Timersteuerung, zum Rückschalten in den Stand-by-Betrieb möglich. In der praktisch erprobten Schaltung wurden folgende Bauteile verwendet:The Ladeelko ( 7 ) has the task to provide the power to turn on the relay. The capacitor ( 4 ) is sized so that the increased power consumption of the relay coil is compensated. In an embodiment of the circuit can, for. B. an optocoupler for forwarding the commands to the main computer can be used. Furthermore, via an optocoupler feedback of commands from the main computer, z. B. timer control, for switching back to stand-by mode possible. In the practically tested circuit, the following components were used:
