  • the infrared remote control signal transmission unit 30 transmits the infrared remote control signal to the infrared remote control signal receiving port 72 of the controlled appliance, or transmits the manual shutdown button signal to the controlled appliance through the manual shutdown button signal transmission unit 120. Manually shutting down the button 102 of the controlled appliance may not be received correctly and the controlled appliance cannot be turned on.
  • the switching unit 40 of the controlled electrical power source is controlled by the control unit 10 to control the power supply 80 of the controlled electrical appliance, and is composed of the switching device and its driving circuit.
  • the control of the controlled electrical power source 80 can be performed by turning on or off the external power input circuit 81 of the controlled electrical power source; or by turning on or off the DC circuit 82 after being rectified by the controlled electrical power source; or by being turned on or off.
  • the DC circuit 83 is controlled after the electrical power source is filtered; or the controlled electrical power source 80 is turned on or off by turning on or off the power supply circuit 84 of the controlled electrical power control chip.
  • the switching device used by the control unit of the controlled electrical power supply 40 can be a relay, a thyristor, a crystal switching device or a one-way crystal switching device and a bridge rectifier circuit.
  • the switching unit 40 of the controlled electrical power source may have an independent power supply circuit 41 to provide the switching device.
  • the driving current of ⁇ is also turned off when the switching device is turned off.

Abstract

L'invention concerne un circuit de commande pour éliminer la consommation de puissance absorbée au repos d'une source d'alimentation d'un appareil pouvant être commuté au moyen d'une commande infrarouge à distance comprenant : une unité de commande, une unité de connexion de récepteur de signal de commande infrarouge à distance, une unité de transmission de signal de commande infrarouge à distance, une unité de commutation destinée à la source d'alimentation de l'appareil commandé et une unité d'alimentation. Le circuit de commande pour éliminer la consommation de puissance absorbée au repos d'une source d'alimentation d'un appareil pouvant être commuté au moyen d'une commande infrarouge à distance, via la détection d'un signal de commande infrarouge à distance reçu, évalue si l'appareil commandé passe ou se trouve à l'état au repos et a besoin d'être allumé, et éteint la source d'alimentation de l'appareil commandé une fois qu'il est passé à l'état de repos ; allume la source d'alimentation de l'appareil commandé lorsqu'il se trouve à l'état de repos et a besoin d'être allumé, et transmet le signal d'allumage à un port de réception de signal de commande infrarouge à distance de l'appareil commandé pour allumer l'appareil commandé une fois que la source d'alimentation a effectué le préchauffage, ce qui permet d'éliminer la consommation de puissance absorbée au repos d'une source d'alimentation d'un appareil pouvant être commuté au moyen d'une commande infrarouge à distance.
