It can also be assumed that in normal operation there is an additional power consumption of at least 100 watts, which of course depends on the size of the model.

  • the network relay 11 is switched off.
  • the television set is therefore disconnected from the network. If a command is sent via the infrared remote control 3, since the signal path B from the infrared remote control to the television set is not active, it is only transmitted via the signal path A from the infrared remote control to the power-saving circuit A. If the command from the infrared remote control 3 is recognized by the IR threshold circuit as a valid command or a command to be evaluated, the evaluation electronics 14 switch on the mains relay 11 and thus the television set into the standby mode. A command from the infrared remote control 3 can be a valid or evaluated command.

  • the evaluation electronics 14 recognizes on the basis of the measured mains current I n that the television is now in normal operation and, with a hold circuit, causes the mains relay 11 to remain switched on. If, on the other hand, no further command is received from the infrared remote control, the evaluation electronics automatically switch from standby mode to energy saving mode after a delay of about 15 seconds, for example.
  • the network relay 11 is switched off and it is assumed that the television is in normal operation. If the television set is now switched from the infrared remote control to the standby mode via the signal path B, the power-saving circuit recognizes this operating state on the basis of the measured mains current I n .
  • the evaluation electronics again checks whether, within the delay time of 15 seconds, it is possible to switch back to a channel. If this is not the case, the evaluation electronics switch back to the power saving mode by switching off the mains relay 11.

The latter can be advantageous if, for example, not only a television, but also a video or satellite system has to be switched on and off with the power-saving circuit. With additional devices to be switched, the power requirement in standby mode and of course the current threshold to be set also change.
  • the power-saving circuit can also be constructed such that, in addition to the IR receiver 9, there is a preferably potential-free input (not shown). This ensures that the switching on of the electronic device 2 can also take place via a button or a relay or the like.

Abstract

L'invention concerne un circuit économiseur de courant (1), destiné à un appareil électronique (2) du domaine de l'électronique grand public qui peut être commandé par une télécommande à infrarouge (3) ordinaire et peut fonctionner en mode normal, alimenté par le secteur, et en mode veille, également alimenté par le secteur. Selon l'invention, il est prévu en outre un mode 'économie de courant' selon lequel l'appareil électronique (2) est coupé du secteur. Ce circuit économiseur de courant peut être commuté avant l'appareil électronique dans la commande du réseau, en tant qu'unité séparée. Il présente un récepteur infrarouge (9) indépendant, n'appartenant pas à l'appareil électronique, servant à recevoir les signaux de commande de la télécommande à infrarouge (3), ainsi qu'un dispositif pour mesurer le courant du secteur de l'appareil électronique (2) avec un circuit de seuil pour détecter le mode veille sur la base du courant du secteur mesuré et d'un seuil de commutation. L'avantage de ce circuit économiseur de courant réside dans le fait qu'il peut être utilisé facilement et de façon universelle, quel que soit l'appareil utilisé.
