Abstract

Die Erfindung betrifft ein Verfahren zum Abschalten des Standby-Betriebs eines Fernsehempfängers mit einem im Gerät angeordneten Mikroprozessor (3). Der Mikroprozessor (3) wird dabei als Zeitschaltuhr geschaltet, so dass der Empfänger nach einer vorher definierten Zeit des Standby-Betriebs völlig abgeschaltet wird. Hierzu schaltet der Mikroprozessor (3) über einen Verstärker (7) die Auslösewicklung eines Netzschalters (5) ein, worauf dieser in seine Aus-Stellung zurückfällt und das Schaltnetzteil (1) vom Netz (U∼) trennt.The invention relates to a method for switching off the standby mode of a television receiver with a microprocessor (3) arranged in the device. The microprocessor (3) is switched as a timer so that the receiver is completely switched off after a predefined period of standby mode. For this purpose, the microprocessor (3) switches on the release winding of a power switch (5) via an amplifier (7), whereupon it falls back into its off position and disconnects the switched-mode power supply (1) from the mains (U∼).

Description

Die Erfindung betrifft ein Verfahren zum Abschalten des Standby-Betriebs eines Fernsehempfängers, der einen Mikroprozessor enthält.The invention relates to a method for switching off the standby mode of a television receiver which contains a microprocessor.

Moderne Fernsehempfänger, insbesondere Farbfernsehgeräte, sind meist mit Fernbedienung ausgerüstet und weisen drei Betriebszustände auf, nämlich ausgeschaltet, den Standby- oder Wartebetrieb und eingeschaltet mit Bild- und Tonempfang.Modern television receivers, in particular color television sets, are usually equipped with a remote control and have three operating states, namely switched off, standby or waiting mode and switched on with image and sound reception.

Während des Standby- oder Wartebetriebs wird der Infra.- rot-Vorverstärker und eine Empfangs-Dekoderschaltung über ein Standby-Netzteil mit Strom versorgt. Dieses Standby-Netzteil kann ein separates Netzteil sein, das aus 50 Hz-Transformator, Gleichrichtung, Siebung und Stabilisierung besteht, oder es kann das im Gerät vorhandene Schaltnetzteil auch während des Standby-Betriebs weiterlaufen.During standby or waiting mode, the infrared preamplifier and a receive decoder circuit are supplied with power via a standby power supply. This standby power supply unit can be a separate power supply unit consisting of a 50 Hz transformer, rectification, screening and stabilization, or the switching power supply unit in the device can also continue to operate during standby mode.

Üblicherweise bleibt das Fernsehgerät den ganzen Tag über in Standby-Funktion, und dies wird dem Benutzer durch ein Lichtzeichen, z. B. einer roten LED, angezeigt. Hiermit soll der Benutzer daran erinnert werden, daß er am Abend das Gerät ausschaltet und damit aus Sicherheitsgründen das Gerät völlig vom Netz trennt.Typically, the television remains in standby throughout the day and this is indicated to the user by a light signal, e.g. B. a red LED. This is to remind the user that he switches off the device in the evening and thus completely disconnects the device from the mains for safety reasons.

Der Standby-Betrieb verursacht zwar nur einen geringen Stromverbrauch von ca. 10 W, hat aber ein statistisch nicht zu vernachlässigendes Sicherheitsrisiko, weshalb empfohlen wird, den Empfänger nachts und während längerer Abwesenheit, z. B. vor dem Urlaub, völlig auszuschalten.The standby mode only causes a low power consumption of approx. 10 W, but has a statistically insignificant security risk. B. before vacation, switch off completely.

Weiterhin besteht die Gefahr, daß beispielsweise eine Lichtspiegelung als Infrarot-Einschaltbefehl falsch interpretiert wird, und der Fernsehempfänger somit unbeabsichtigt eingeschaltet wird.There is also the risk that, for example, a light reflection is interpreted incorrectly as an infrared switch-on command, and the television receiver is thus switched on unintentionally.

Aufgabe der Erfindung ist es, ein Verfahren zum völligen Ausschalten eines Fernsehempfängers der eingangs genannten Art anzugeben, mit dem die vorstehend gezeigten Schwierigkeiten behoben werden.The object of the invention is to provide a method for completely switching off a television receiver of the type mentioned, with which the difficulties shown above are eliminated.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Mikroprozessor als Zeitschaltuhr geschaltet wird und den Empfänger nach einer bestimmten Zeit abschaltet.This object is achieved in that the microprocessor is switched as a timer and switches off the receiver after a certain time.

Damit wird der Vorteil erzielt, daß mit Hilfe des im Fernsehempfänger vorhandenen Mikroprozessor, z. B. im Frequenzsynthese-Abstimmsystem, eine Zeitschaltung erstellt werden kann, die das Gerät nach einer vorher bestimmten Zeit, beispielsweise 5 Stunden Standby-Betrieb, völlig ausschaltet. Durch das erfindungsgemäße Verfahren wird erreicht, daß nach einer gewissen Zeit des. Standby-Betriebs das Gerät völlig vom Netz getrennt wird, wodurch das Brandrisiko verringert und zusätzlich eine, wenn auch geringe, Stromersparnis erzielt wird.This has the advantage that with the help of the existing microprocessor in the television receiver, for. B. in the frequency synthesis tuning system, a time circuit can be created, which completely switches off the device after a predetermined time, for example 5 hours of standby mode. It is achieved by the method according to the invention that after a certain period of standby operation the device is completely disconnected from the mains, thereby reducing the risk of fire and additionally achieving an, albeit small, power saving.

In einer besonders vorteilhaften Ausführungsform des erfindungsgemäßen Verfahrens geschieht das Abschalten des Gerätes dadurch, daß die Magnetwicklung des Netzschalters mit einem Stromimpuls bzw. einer Unterbrechung beaufschlagt wird, so daß der Schalter in die Ruhe-Position zurückspringt. Zum Wiedereinschalten des Gerätes muß dann der Netzschalter wie üblich neu gedrückt werden.In a particularly advantageous embodiment of the method according to the invention, the device is switched off by the magnetic winding of the mains switch is subjected to a current pulse or an interruption, so that the switch springs back into the rest position. To switch the device on again, the mains switch must be pressed again as usual.

Die Erfindung wird anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Durch Betätigen des Netzschalters (mit magnetischer Auslösung) (5) wird das Gerät mit einer Spannung UN, beispielsweise 220V versorgt. Im Standby-Betrieb arbeiten zweckmäßigerweise nur die Baugruppen Fernbedienungsempfänger (4) und Mikrocomputer (3), die z.B. aus einem Schaltnetzteil (1) versorgt werden, das auch das TV-Chassis (2) im Ein-Zustand mit den Betriebsspannungen versorgt. Nach Dekodierung eines Einschaltbefehls schaltet der Mikrocomputer (3) über einen Verstärker (8) das Relais (6), das die Betriebsspannungen auf das Chassis (2) schaltet. Ein Ausschaltbefehl bewirkt, daß das Relais (6) abfällt. Wenn eine definierte Zeit seit dem letzten Ein-Betrieb (z.B. 5 Stunden) oder seit dem letzten Steuerbefehl durch den Benutzer (z.B. 24 Stunden) vergangen ist, schaltet der Mikrocomputer (3) über den Verstärker (7) die Auslösewicklung des Neztschalters (5) ein, worauf dieser in seine Aus-Stellung zurückfällt, und das gesamte Gerät vom Netz trennt. Der Schalter (5) kann selbstverständlich auch per Hand wieder in seine Ruhe-Stellung gebracht werden.The invention is explained in more detail using an exemplary embodiment shown in the drawing. By pressing the mains switch (with magnetic release) (5) the device is supplied with a voltage UN, for example 220V. In standby mode, only the remote control receiver (4) and microcomputer (3) modules, which e.g. can be supplied from a switching power supply (1), which also supplies the TV chassis (2) with the operating voltages in the on state. After decoding a switch-on command, the microcomputer (3) switches the relay (6) via an amplifier (8), which switches the operating voltages to the chassis (2). A switch-off command causes the relay (6) to drop out. If a defined time has passed since the last switch-on operation (e.g. 5 hours) or since the last control command by the user (e.g. 24 hours), the microcomputer (3) switches the trigger winding of the tilt switch (5) via the amplifier (7). whereupon it falls back into its off position and disconnects the entire device from the mains. The switch (5) can of course also be returned to its rest position by hand.
