Definitions

  • the present invention relates to a control system for at least one electrical consumer, in particular an audio or video device, comprising a wireless control device with transmitting means able and adapted to transmit a control signal wirelessly to the consumer.
  • the invention also relates to a switching device for use in such a control system.
  • many modern electrical consumers such as in particular audio and video equipment, generally also comprise a control unit with which the consumer can be controlled wirelessly from a distance, a so-called remote control, hi such a case the consumer comprises primary receiving means for receiving and at least transmitting a control signal for processing purposes from the wireless remote control, and primary switching means for switching an electric power supply of the consumer on the basis of an on/off signal from the remote control or the on/off key.
  • this increased convenience of use also has a drawback however.
  • the device will nevertheless have a certain standby consumption in the standby mode.
  • this standby consumption typically lies in the order of 1 to 10 Watt. Calculated with a total standby duration of an average of 20 hours a day and between 5 and 10 of such users, this results in an energy loss of between 35 and 75 kWh per household per year. At a price per kilowatt hour of €0.25 it would thus be possible to save a minimum in the order of €25 a year if this standby consumption could be limited.
  • the present invention has for its object, among others, to provide a system and device for at least one electrical consumer, with which such an energy-saving can be realized to at least a significant extent without appreciably detracting from the overall convenience of use.
  • a control system of the type stated in the preamble has the feature according to the invention that the consumer is connected to a power supply via a secondary switching device, that the secondary switching device comprises secondary switching means which are connected in series to the consumer, and that the secondary switching device comprises secondary receiving means which are able and adapted to receive a control signal from the wireless control device and to switch the secondary switching means as a result.
  • the secondary switching device just as the consumer, comprises receiving means for receiving a control command from the control unit, the secondary switching device can be wholly remote controlled, so that little or no convenience of use is lost. As soon as the consumer has to be switched on again, the secondary switching device receives a relevant signal from the control unit and then restores the electric power supply connection to the consumer and itself optionally switches on the consumer or awaits a subsequent control command therefor.
  • the secondary switching device can be folly controlled per se at the command of the control unit, although in a preferred embodiment the control system according to the invention has the feature that the secondary switching device comprises detection means for recording a maintaining current to the consumer, and that the secondary switching device is able and adapted to switch the secondary switching means to a non-conductive mode when the maintaining current falls below a predetermined threshold value.
  • the secondary switching device thus detects from the level of the maintaining current whether the consumer is in switched-on mode or standby mode, and in the latter case to switch off the current to the consumer.
  • a particular embodiment of the control system according to the invention has the feature here that the secondary switching device comprises clock means, in particular manually adjustable clock means, which determine a period of time for which the maintaining current must be maintained below the threshold value before switching the secondary switching means to the non-conductive mode.
  • the secondary switching device will thus not switch off the consumer immediately, but only after the set period of time, so that the convenience of use remains unchanged within this period of time.
  • a longer period of time leaves the convenience of use unchanged for a longer time, so that the secondary switching device switches off the consumer completely only in the case of for instance holiday or other long-term absence, while a shorter period of time will result in a greater energy-saving.
  • the secondary switching device can be embodied such that it will respond only to determined control commands from the control device to switch the consumer on or off.
  • a further particular embodiment of the control system according to the invention has the feature that the secondary receiving means are able and adapted to receive a random control signal from the control means and to switch the secondary switching means as a result to a conductive mode.
  • the secondary switching device will thus always switch on or remain switched on when it receives any random control signal from the control unit, and only switch off when the consumer has been switched to the standby mode. This latter can be detected from a momentary maintaining current of the consumer or can be inferred from a specific content or coding of the control signal, to which the secondary switching device can then respond accordingly.
  • control system has the feature that the transmitting means are able and adapted to transfer infrared signals, and that the secondary receiving means comprise an infrared-sensitive sensor.
  • the invention is here compatible with an average remote control of an electrical consumer.
  • the primary receiving means of the consumer herein usually comprise a sensor which is arranged in a line of sight on the consumer.
  • the secondary switching means are on the other hand usually situated on a power supply side of the consumer, this frequently being behind or under the consumer and out of sight.
  • a further preferred embodiment of the control system according to the invention has the feature here that an elongate optical conductor, in particular a glass fibre, is coupled to the optical sensor of the secondary receiving means.
  • the light conductor will in this case provide for transport of an optical control signal from an outer end thereof to the optical sensor of the secondary switching means, which can then be situated outside a line of sight without practical problems. This is because the relatively inconspicuous and thereby hardly noticeable outer end of the optical conductor can be positioned close to the sensor of the consumer itself or at another practical location in sight of the control unit.
  • the light conductor requires no electric power supply and can be embodied with an almost unlimited length without problem in order to thus provide a solution in any practically possible situation.
  • the secondary switching device can per se be integrated into the consumer, although a particular embodiment of the control system according to the invention has the feature that the secondary switching device is provided at least substantially in a housing separate from the consumer.
  • the secondary switching device is thus a separate unit which can optionally be applied only later in a consumer and which is herein universally applicable.
  • a further particular embodiment of the control system has the feature here according to the invention that the housing comprises first electrical connecting means which can be received fittingly in a complementary electrical connection of a mains electricity supply, as well as second electrical connecting means complementary thereto for receiving fittingly therein electrical connecting means of the consumer, and that the secondary switching means are connected between the first and second connecting means, and more particularly that the connecting means comprise coupling means from a group comprising an electric power supply plug connection and an electrical socket connection for coupling to a mains electricity supply.
  • the secondary switching device is thus provided as an intermediate unit which can be placed between a power supply connection of the consumer and an original connection to the mains electricity supply in simple manner using the original connecting means.

  • this usually involves infrared signals, although the invention can also be applied in combination with radio signals, this providing the extra advantage that no line of sight is required for this purpose between the control unit and the receiving means.
  • the transmitted control commands can be received by primary receiving means 10 of the consumer, which, in addition to a suitable optical sensor IRl, also comprise the circuits and control logic in the form of a logic control unit 13 which are necessary for processing of the control commands.
  • a manual, physical operating key 11 is also coupled to control unit 13 to also enable the consumer to be switched on or off as desired without control unit.
  • Control unit 13 controls (primary) switching means 12 coupled thereto, which are provided in the consumer and able to switch an electric power supply of the consumer.
  • primary switching means 12 will never fully interrupt the power supply to the consumer when an apparatus is switched off, but instead set the apparatus to a so-called standby mode.
  • the standby mode maintains at least a maintaining current of the primary receiving means and control unit 13 so that they remain operational and, in some cases, also of other electrical components so that they require no warm-up time or start-up cycle when restarted.
  • a set-up undoubtedly enhances the user convenience of the apparatus in question, it does however have the drawback that the standby mode of the consumer undeniably entails a certain loss of energy, particularly if the equipment is left unused for a long(er) period of time.
  • Secondary switching device 20 comprises secondary switching means 22 which are connected in series to primary switching means 12.
  • Secondary switching means 22 comprise a set of switch contacts s3,s4 of a switching relay REL, the control contacts sl,s2 of which are controlled by a control circuit 23.
  • Control circuit 23 is coupled for this purpose to a base of a bipolar transistor T, a collector of which is connected to a first control contact si of relay REL and an emitter of which is coupled to a second power supply line 32.

  • secondary switching device 20 comprises secondary receiving means in the form of a second optical sensor IR2, which is able and adapted to detect a control signal transmitted by the control device.
  • Secondary optical sensor IR2 is likewise coupled to a control unit 23 of the secondary switching device.
  • control circuit 23 will activate relay REL.22, after which secondary switching means 22 will close and the consumer is coupled to main power supply 30 via both power supply lines 31,32.
  • a power consumption of the consumer is meanwhile recorded in the form of a voltage drop over a resistance R ⁇ 0x in second power supply line 32.
  • This signal is then sent to control circuit 23 in amplified form via an operational amplifier AMP.
  • Control circuit 23 continuously monitors the level of this signal. As long as a high level is detected, corresponding to a significant energy consumption by the consumer, relay REL,22 remains activated and the consumer retains its power supply.
  • Control circuit 23 now records a low signal from the amplifier AMP. At this moment the control circuit starts clock means CLK coupled thereto in order to deactivate relay REL,22 only after a predetermined and adjustable period of time, during which the consumer is in the standby mode and the output signal of the amplifier thus remains low. Second power supply line 32 is thus interrupted completely so that the energy consumption of the consumer decreases to zero.
  • control circuit 23 requires a new control signal from second receiving means IR2. This signal is generated to control unit 23 by the secondary receiving means when a control command is received from the wireless control unit. Control unit 23 then reactivates relay REL,22, whereby consumer 10 is reconnected to power supply 30. The consumer now switches on or switches to the standby mode, and can be further controlled by the user in simple manner, also in the latter case, by means of successive control commands to be generated using the control unit.

  • Secondary switching device 20 is connected between the two connections 41,42 in housing 25.
  • the secondary optical sensor IR2 is advantageously coupled to a first outer end of an elongate optical conductor 50, a so-called glass fibre or optical fibre.
  • a free outer end 51 thereof is available for placing in a line of sight. This is particularly advantageous if the plug- socket housing 20 is for instance situated behind an appliance of the consumer or otherwise out of sight.
  • a ballast block can be arranged over the free outer end 51, with which the outer end can be positioned and optionally fixed in stable manner.
  • FIG 3 A second specific implementation of the control circuit according to the invention, in particular in the form of that of figure 1 , is shown in figure 3.
  • secondary switching device 20 is received in a connecting plug 26 with connecting pins 41 of a power supply cable 27 for the consumer.
  • the power supply cable 27 carries a standard connector with electrical connections 42 therein for the consumer.
  • the secondary optical sensor IR2 is also accommodated in housing 27, but can be approached via an elongate optical conductor 50 from a distance and when out of sight.
  • This embodiment is otherwise similar to that of figure 2.
  • the shown circuit fulfills its function, different add-ons and variations thereof can be realized with the same objective. Additional functionality can particularly also be added thereto for the purpose of temporarily buffering a fresh control command when the consumer is switched off, and generating it thereto, optionally in coded form, after the consumer has been switched on. Suitable transmitting means which communicate with the receiving means of the consumer can for instance be coupled for this purpose to the secondary switching device. It is thus possible to avoid a control command having to be generated repeatedly when a consumer is switched off. It is also possible to control the secondary switching means in coded manner directly from the wireless control unit, wherein specific keys (combinations), optionally programmed as such, process the desired complete switching on or off of the consumer.
