Definitions

  • the present invention relates to a device and method for reducing standby power consumption and has particular application to electrical appliances such as home entertainment appliances when used in home automation systems.
  • the present invention provides a device for controlling the supply of mains power, the device including: a mains power input for connection to a mains power supply; a mains power output; a control interface for receiving control signals; and switching means for selectively allowing mains power to pass from the input to the output based on the control signals.
  • the control interface may be arranged to be hard wired to a control system.
  • the control interface may include an RS232 interface.
  • the switching means may include a relay.
  • the power to operate the relay may be derived from the control interface.
  • the device may be arranged to provide an output indicative of the state of the switching means. This enables two way communication between the device and a control system.
  • the device may be further arranged to periodically operate the switching means to allow mains power to pass from the input to the output. This ensures that devices which store internal preset information in memory do not lose these settings due to being isolated from mains power for an extended period of time.
  • the present invention provides a power socket including a device according to the first aspect of the invention.
  • the present invention provides a powerboard including a device according to the first aspect of the invention.
  • the present invention provides an electrical installation including a device according to the first aspect of the invention.
  • the present invention provides a method of controlling the availability of power to an electrical appliance including the steps of: providing a device according to the first aspect of the invention; connecting the mains power input of the device to a mains power supply; deriving power for the electrical appliance from the mains power output of the device; and controlling the device to control the availability of mains power to the appliance.
  • Figure 1 is a schematic diagram of a device for controlling the supply of mains power according to an embodiment of the invention
  • Figure 2 is a schematic view of a power socket including the device for controlling the supply of mains power according to figure 1 ;

  • Figure 4 is a schematic view of a power board including a device for controlling power according to figure 1 ;
  • Figure 5 is a schematic view of an electrical installation including a device for controlling power according to figure 1.
  • a device 10 for controlling the supply of mains power including a mains power input 12 for connection to a mains power supply and a mains power output 14.
  • Device 10 includes a control input for receiving control signals in the form of RS232 interface connection 16.
  • Switching means for selectively allowing mains power to pass from the input 12 to the output 14 is provided in the form of dual pole relay 18 which operates in response to control signals received at the RS232 interface 16.
  • Relay 18 switches the active and negative connections of the mains supply.
  • Relay 18 includes a signal output which is indicative of the position of the relay (ON or OFF). This signal output is connected to the RS232 interface to enable two way communication between a control system and device 10. That is to say, the state of the signal output is visible to the control system so that the control system is aware of the state of relay 18.
  • the power required to drive the relay is derived from the control system via the RS232 connection.
  • input 12 is connected to a mains power supply and output 14 provides power to an electrical appliance.
  • the supply of power to the electrical appliance may thus be controlled by operation of relay 18 which is controlled by way of signals on one or more of the connections of the RS232 interface.
  • relay 18 is controlled by way of signals on one or more of the connections of the RS232 interface.
  • an electrical appliance may be switched on or off by controlling the supply of mains power.
  • the electrical appliance does not utilise its own internal "Standby" function. Mains power is completely denied to the appliance and it consumes no power in the off state.
  • Some electrical appliances such as FM tuners or television sets with internal tuners store information such as preset frequencies or users changes to preset frequencies in a volatile memory which is powered by a capacitor or small internal rechargeable battery. If devices of this type are deprived of electricity for an extended period of time, which maybe of the order of about two weeks, then the settings may be lost when power is returned to the device as it reverts to its default settings.
  • the device 10 may further include an internal clock arrangement which periodically outputs its own control signal to operate the relay 18 to allows mains power to pass to the output for a short period of time to maintain charge in the electrical appliance to prevent it from losing settings information.
  • the internal clock can be configured to provide mains power for a period of 15 minutes every 48 hours.
  • the internal clock resets to zero. If the device 10 is put into the on condition then the clock is deactivated or ignored. If the clock has caused device 10 to go into the on state for the 15 minute period, and a user decides to turn on the device 10 during this period, then the clock is deactivated or ignored.
  • the internal clock may be powered from mains power, by drawing power from the control signal lines, or by way of a capacitor or rechargeable battery.
  • a power socket 20 is shown incorporating device 10.
  • Power socket 20 is arranged so that availability of power at the socket depends upon the state of the relay in device 10.
  • An RS232 connection is provided to the power socket as part of device 10 to allow connection to a control system. This connection may be hidden from view. Availability of power at the power socket 20 may thus controlled by way of the RS232 interface.
  • Control system 22 may thus control the on or off state of appliances (not shown) by controlling the availability of power at the power sockets 20 to which they are connected.
  • a powerboard 30 which includes a number of mains power sockets 32.
  • Powerboard 30 includes a device 10 as shown in figure 1.
  • Powerboard 30 is configured so that the availability of mains power at the sockets 32 is controlled by device 10. Powerboard 30 derives power from power socket 40 in the usual manner by way of mains cable 34. Power is always available from socket 40.
  • Socket 40 includes an RS232 through connection to pass control signals from control system 22 to powerboard 10.
  • Control system 22 is hard wired to socket 40 in a manner hidden from view.
  • the RS232 control signals are carried from socket 40 to device 10 by way of a control cable 36 having RJ45 type connectors at either end.
  • control system 22 may control the on or off state of all devices connected to powerboard 30 by controlling the availability of power at outlets 32. All outlets 32 on powerboard 30 are controlled in unison.
  • FIG. 5 an electrical installation is shown to illustrate how availability of power from an entire mains loop in a building may be controlled.
  • Mains power supply 50 is connected via device 10 to a mains power loop bearing several conventional power sockets 42.
  • power may be denied to all of power sockets 42 by way of control system 22 controlling device 10. All power sockets are controlled in unison.
  • the various power sockets 20, 40, 42 mentioned had capacity to receive a single electrical plug to power one appliance.
  • each of these power sockets could each have capacity to receive one or two or more mains power plugs.
  • the power to operate relay 18 was derived from the RS232 signal lines.
  • power to drive the relay could be derived from another source of power including mains power, or batteries. Any reference to prior art contained herein is not to be taken as an admission that the information is common general knowledge, unless otherwise indicated.
