Description

A NON-ESSENTIAL CIRCUIT SWITCH SYSTEM TECHNICAL FIELD

[0001] The present invention relates to a non-essential circuit switch system to enable a user to designate at least one circuit within a system as essential for maintaining a connection to a power source and at least temporarily disconnecting or isolating at least one circuit designated as non-essential from the power source.

BACKGROUND ART

[0002] When a person is last to leave a building (office, school, factory, home, etc.), they will often check that all the non-essential appliances (lights, fans, kettle microwave, coffee machine, printer, air conditioning, radio, pie warmer, um, etc.) have been turned off. Leaving items on can be dangerous (cause fires) and increases the electricity charge.

[0003] Leaving appliances (lights, fans, kettle microwave, coffee machine, printer, air conditioning, radio, pie warmer, urn, etc.) on or in standby mode after hours and over the weekend can greatly increase the electricity bill. The average office will be open 8-10 hours per 24 hour day. This leaves 14-16 hours of every work day where the premises are not in use and more on weekends and public holidays. If non-essential items are left on during these periods whether it be due to forgetfulness, laziness or negligence this will add expense unnecessarily to the electricity bill. Recognition of these issues has meant that electrical power control devices for buildings are available.

[0004] One such system is made by Clipsal and is called “C-Bus”. This system is a microprocessor-based control and management system for buildings and homes, used to control lighting and other electrical services such as pumps, Audio Visual Devices, Motors, etc. The system can provide simple ON/OFF control of a lighting circuit, or variable (analogue) type control, such as electronic dimmable fluorescent ballasts, and can be used to control virtually any type of electrical load. Each C-Bus device has its own in-built microprocessor and “intelligence”, allowing units to be individually programmed. This product focuses on home automation, and is an expensive luxury item and not installed in the average homes or businesses.

[0005] There are also other home automation products and systems on the market that allow a user to remotely control what electrical items are on or off and to control the switch. One such system is made by Belkin. The Belkin system offers home automation and is used to control devices/lights from an application via WIFI.

[0006] Further, power saver devices are available but these items normally use filtering to smooth the power quality within homes. Standby power controllers (remote power point switch) are also available.

SUMMARY OF INVENTION

[0008] The present invention is directed to a non-essential circuit switch system, which may at least partially overcome at least one of the abovementioned disadvantages or provide the consumer with a useful or commercial choice.

[0009] With the foregoing in view, the present invention in one form, resides broadly in a non-essential circuit switch system for a premises power supply, the system including a) a user interface to allow a user to control operation of the system; b) a transmitter associated with the user interface to transmit instructions; c) a receiver to receive instructions from the transmitter; d) a controller associated with the receiver and operating control software to receive information from the receiver; e) electrical power switching hardware associated with the premises power supply to switch one or more electrical circuits of the premises on and off according to instructions issued by the user via the user interface.

[0010] In another form, the present invention resides in a non-essential circuit switch system for a premises power supply, the system including a user interface to allow a user to control operation of the system, the user interface associated with a transmitter to transmit instructions from the user interface, at least one control node including a receiver to receive instructions from the transmitter and a controller associated with the receiver and operating control software to receive information from the receiver and electrical power switching hardware associated with an electrical system of a premises to switch one or more electrical circuits of the premises on and off according to instructions issued by the user via the user interface.

[0011] In yet another form, the present invention resides in non-essential circuit switch system for a premises power supply, the system including a node associated with a user interface to allow a user to control operation of the system, a controller associated with the node and operating control software to receive information from the user interface and electrical power switching hardware associated with the premises power supply system to switch one or more electrical circuits of the premises on and off according to instructions issued by the user via the user interface.

[0012] At its core, the system of the present invention provides a user with a remote user interface used to switch (on, off) non-essential circuits in a premises when the appliances on those circuits are not needed or when people have left the building.

[0013] The premises in relation to which the system of the present invention can be provided may be of any type. For example, the premises may be a building, part of a building such as a tenancy for example or include more than one building.

[0014] The premises may be of any type including a business or but the system of the present invention may be implemented in other types of structures including movable structures such as temporary office buildings which may be present on building sites of worksites or even caravans for example.

[0015] Generally, there are three main elements present in the system of the present invention, these elements typically including a user interface and transmitter provided on one or more elements (such as a wall mounted interface with display and/or a computer device operating interface software), a receiver and controller provided in a second element (a “node”) and the switching hardware which is generally provided in relation to the second element but may be a separate, third element. In some embodiments, there may be a fourth element in the form of remote switching hardware.

[0016] In preferred embodiments, the remote switching hardware is separate from the user interface and transmitter, receiver and controller, and node elements. The remote switching hardware may include one or more devices each associated with individual power sockets or outlets in these one or more devices may be controllable individually using the controller of the present invention.

[0017] In preferred embodiments, the one or more devices are mounted between a general power outlet in a building and an appliance such as a refrigerator, toaster, lamp etc. The remote switching hardware may receive instructions from a second element, e.g. node, to switch the respective appliance on or off. Advantageously, where a building circuit has been identified as essential but has one or more non-essential appliances attached thereto, the non-essential appliance may be remotely switched off (or on).

[0018] Each device of the remote switching hardware may include a Power Line Communications (PLC) coupling circuit to interface communications to the building circuit; protection circuits used to protect the node from overheating, over current and general faults; switches, buttons and indication LEDs used as Human Machine Interface (HMI); hardware for switching the circuit on/off; a microcontroller; and/or a programming port for updating firmware.

[0019] The user interface and transmitter element will normally be provided such that the user interface allows a user to control the system as well as to configure the system. Any type of user interface can be provided. For example, in a simple embodiment, the user interface may be provided in or as a simple wall panel with one or more switches allowing control of circuits as required. In a more advanced or complex embodiment, the user interface may be provided as part of the software application operating on a computing device. Normally, these will be the extremes of the spectrum of complexity of the user interface.

[0020] In one embodiment, the user interface and transmitter are provided with a wall mounted control unit including at least one switch or panel of switches for user input of instructions to the control unit to issue instructions to the controller. The transmitter may include an encoder in order to encode instructions before being transmitted. The wall mounted user interface and transmitter will preferably include a display in order to display parameters for a user. An integrated battery and power supply unit may be included.

[0021] In an alternative embodiment, the user interface and transmitter may be provided as a software application operating on a computing device such as a smartphone or tablet for example. Preferably, the software application in this form will typically reproduce the functionality allowing the user to control the system of the present invention using their smartphone or tablet. The functionality provided by the software application operating on the computing device will typically allow control of all aspects of the system and where provided, will provide a user with control over the master node as well as any one or more slave nodes.

The system of the present invention will typically utilise the communication pathways which are provided with computing devices such as smart phones or tablets in order to send instructions and receive information from the one or more nodes within the system to the software application.

[0022] As an illustrative example, the user interface may include a transmitter for transmitting instructions; a receiver for receiving instructions, data and status updates from a node; an LCD display, buttons and switches; a timer in the form of a clock for timestamping data; a SD card for storing data, for example consumption v time; a micro controller for controlling; and/or a programing port for updating firmware.

[0023] The present invention may include at least one control unit. A control unit may be as a wall mounted control unit, typically adjacent a main entrance or exit. As will be explained below, a control unit may be provided as a personal computing device operating a software application which can be used to accept instructions and transmit the instructions to the receiver.

[0024] Preferably, a wall mounted control unit will have a wall plate, similar in size and shape to a conventional light switch. In some embodiments, the wall plate may be slightly larger than a conventional light switch. In some embodiments, the wall plate may be about two times larger than a conventional light switch. It is preferred that the wall plate be provided with touch sensitive buttons to allow operation of the system. Alternatively, push buttons may be used.

[0025] The control unit may have any number of operating channels and can be single channel or multichannel. Instructions in relation to different circuits may be issued on different channels.

[0026] The control unit typically includes at least one “on” button and an “off” button. Pairs of buttons may be provided for each circuit or alternatively a single button can be provided with the button cycling between instruction to connect the circuit (on) and instructions to disconnect the circuit (off). More advanced control units may have graphical representations of the circuits generated and displayed on a display of a personal computing device for example for a more intuitive operation.

[0027] The system may preferably operate such that the software application operating on the personal computing device can be used as the control unit.

[0028] The control unit may also typically include a timer button. Use of the timer button will typically allow a user to activate or deactivate a timer functionality to allow the user to connect one or more circuits (on) and to disconnect one or more circuits (off) at one or more particular times. Alternatively, the control unit may include one or more selection buttons and an LCD display. Timer may be a selectable option through the LCD display menu where current time can be set and also the desired off/on time can be programed along with other parameters.

[0029] The control unit of the preferred embodiment will preferably include a wireless communication device to allow communication with the receiver. WIFI is one preferred method of wireless communication. Bluetooth is another preferred method of wireless communication but any portion of the electromagnetic spectrum can be used. This will typically allow the control unit to operate as a remote control to issue instructions to the receiver as required. The software application operating on the personal computing device may typically allow the user to control the timer functionality and to connect one or more circuits (on) and to disconnect one or more circuits (off).

[0030] The wall plate control unit according to a preferred embodiment will typically include a plastic or similar housing mounted relative to a wall surface. A forward face of the housing will typically have identified portions provided for switches allowing different functionality. Each of the switches will typically allow communication of control instructions to the controller to control the circuits. Each of the buttons will typically have a function identified thereon, typically using text.

[0031] Each of the switches will also typically have an associated light or similar indicator, preferably an LED, in order to indicate the status of the particular operation initiated by the switch. Typically, the preferred LED will indicate a first colour when initiated and indicate a second colour or be unlit when not activated. Typically, a single light will be provided for each switch. Further, each of the switches may include a Liquid Crystal Display (LCD).

[0032] Control of one or more circuits of the premises power supply utilising the system of the present invention can be directly applied through the user interaction with the switches on the preferred wall plate but can also normally be implemented through instructions stored in the software application which when followed, generate one or more interfaces on a personal computing device (PCD). The instructions are typically followed, normally by the process of the PCD, in order to generate and update an interface in real time according to the user’s interaction with the interface. The user’s interaction with the software application through the interface will typically result in the software application issuing control instructions to the control unit using the respective communication devices provided on the personal computing device and the control unit.

[0033] The personal computing device can be of any type such as a tablet or computer or the like but will preferably be a smartphone or other similar device which is carried by a person and is therefore easily accessible to them at the majority of times. The personal computing device of the preferred embodiment will include a processor having an associated memory for storing instructions and a display upon which an interface can be generated and displayed allowing user interaction with the software application. As mentioned above, the personal computing device will typically include a wireless communication device and normally, personal computers and devices such as those discussed above have access to a number of communications pathways such that information can be transmitted and received via any one or more of a variety of communications pathways. These communications pathways typically include Wi-Fi, Bluetooth as well as telecommunications networks and data links or RFID but any portion of the electromagnetic spectrum could be used. According to the most preferred embodiment, the system of the present invention will operate via Bluetooth.

[0034] Many of these personal computing devices have touchscreens for display, allowing the user to directly interact with the touchscreen in order to interact with the interface. However, a non-touchscreen display can be used with a movable pointer or selection tool in order to allow a user to interact with the interface.

[0035] One or more “buttons” are provided on the interface to allow the user to interact with the PCD and through the PCD, to interact with the system. These are typically portions on the interface allowing a user to input instructions and actions via software operating on the PCD.

[0036] In normal circumstances, and according to the simplest embodiment, the hardware components of the system including the receiver and controller and the switching hardware will be sold in a package with access provided to the software application, typically by download to the purchaser's personal computing device. Once the software application has been downloaded, the personal computing device or software application can then be "paired" with the controller associated with switching hardware of the system. In this particular initial pairing, the personal computing device will typically be provided with information in relation to controller in the premises and an access code, unique to the controller will generally be input into the software application via the personal computing device to pair the devices.

[0037] In the simplest embodiment, this unique identifying code will therefore be an alphanumeric code (or any other suitable type of code) provided with the controller and which is entered into the software application operating on the personal computing device. The software application will typically include a subroutine allowing this to occur when initially pairing the controller with the software application running on the personal computer device.

[0038] Normally the software application operates according to instructions stored in the memory of the personal computing device and put into effect using the processor and controlled by interaction with the user via the interface generated and displayed on the display and/or other input apparatus provided with the personal computer device in order to issue instructions and receive information to control the controller and the switching hardware as required.

[0039] This will preferably allow the software application operating on the personal computing device to operate as a remote control. Preferably, the software application and personal computing device can be used to control each controller within range of the communication device and/or each controller which has been paired with the software application. The preferred signal range of the wireless communication device in the controller is preferably approximately 10 to 20 m although this can be adjusted according to signal strength.

[0040] Preferably, one or more controller may be provided in relation to a structure or building or room within a building and each circuit controllable thereby will normally be provided with the unique designation and/or channel provided for identification. This will allow a user to control each of the circuits individually and independently. There will typically also be provided the ability to control link more than one circuit together such that multiple circuits can be controlled by one “button”. Preferably, the unique designations will be provided to the software application as a part of the pairing process. The process of preparing a Bluetooth enabled device with a software application is relatively well-known.

[0041] The software application normally operates on the personal computing device to generate and display one or more interfaces on the display of the personal computing device and the user can interact with the controller controlling one or more circuits via the interface(s).

[0042] The preferred embodiment of the software application is preferably relatively simple. The first time the software application is initialised (or alternatively at any time there after), the software application may engage one or more of the communications pathways or devices of the personal computing device upon which it is operating to search for one or more controllers which can be paired with the personal computing device. This will typically identify the one or more controllers as device(s) which can be paired. Pairing the one or more controllers with the personal computing device will typically allow the user to control the one or more controllers using the personal computer device. The pairing process may also provide information in relation to the user and/or the personal computing device of the user to the one or more controllers or vice versa. Thereafter, as required, the authorised user will typically use the paired personal computer device to control the one or more controllers.

[0043] The software application will typically provide an interface that allows the designation of each of the one or more controllers which have been paired with the particular personal computing device to be identified. The designations may take any form and may for example be in the form of a room or other location identifier and/or one or more circuits to which certain devices are connected. The interface may provide other information including status of the controller and/or circuits and it may provide this information in any form but preferably, does so graphically.

[0044] The interface generated and displayed on the personal computer device by the software application will typically give an indication of the status of the circuits in the premises in terms of whether the circuits are on or off.

[0045] In operation (once paired with one or more controllers), a user will typically open the software application which will cause the software application to generate and display a “home” interface.

[0046] The preferred home interface will provide a list of paired controllers within range of the personal computer device operating the software application.

[0047] The home interface will typically provide the user with the ability to select a particular circuit to operate or allow a user to search for a particular circuit in order to operate that controller in relation to that circuit.

[0048] Typically, selection of a particular circuit causes the software application to utilise the hardware of the personal computing device to generate and display another interface specific to the circuit that has been selected. This interface may typically include a location or designation of the selected circuit for example may indicate which devices are connected to that circuit.

[0049] The interface will also preferably include one or more action “buttons”. As outlined above, there will preferably be at least an on button, and an off button. The buttons will normally be displayed on the interface and due to the nature of the personal computing device, will typically be activated according to a process applicable to that personal computing device. As indicated above, the majority of personal computing devices which will be used according to the present invention will have touchscreen functionality and therefore, the action buttons can be activated by touching an icon or button produced on the interface.

[0050] Feedback will normally be provided upon actuation by the user and/or during the indicated action taking place. This can be done in any way appropriate to the software application but normally, will involve updating of the interface to include an indicator of the initiation of the action by touching an icon or button and/or during the indicated action taking place.

[0051] The interface generated for the particular circuit, will also typically include a timer set icon or button.

[0052] Any or all of the icons buttons provided on the interface will preferably allow a user to activate and deactivate the functionality chosen according to the button or icon.

[0053] The interface will also typically include a menu button allowing the user to select from different operations or circuits, a home button to return to the home interface and a settings button allowing the user to set personal preferences in relation to the operation of the software application.

[0054] The software application will also allow a user to move the interface in order to change the selected circuit that they wish to control. In many cases, and due to the type of personal computing device used, this can be actuated through swiping the interface either sideways, in either direction or in one direction only or alternatively up and/or down in order to move to the next circuit.

[0055] Actuating the timer set icon or button will typically produce a new or adapted interface allowing the user to set the timer controls. As the new or adapted interface relating to the timer set function is accessed from a particular circuit interface according to the preferred embodiment, changes made will typically be communicated to the particular controller responsible for control of that circuit. The preferred timer set interface will preferably allow a user to input one or more times, days, dates, months or years and the like in order to allow the operator to set one or more specific times when the circuit will be on and off.

[0056] Normally, the user will also be able to choose the appropriate action to be taken at a chosen time. The user will also be able to set the timer activation mode in an activated or deactivated condition. Any mechanism for input of the information or selection of the information can be used and typically, a number of icons or buttons will be provided on the interface to allow selection of the time and activation mode. These types of input mechanisms are relatively well-known but an appropriate type of input mechanism will be selected for the particular input required. For example, when a user is setting a time, there may be a scrolling function or a direct input of a particular time as well as selection of a.m. or p.m. and/or any day or days.

[0057] Normally, there is a return, done or finished button. It will be immediately clear to a person of skill in the art that in order for the timer function to have the applicable use, either the software application will include or have access to a clock function or the control unit will include or have access to a clock function. Typically, the clock function will be provided as a part of the operating system on the personal computing device upon which software application is operating and the software application will typically operate according to that clock function. Once the appropriate time is reached, the software application will then issue instructions to the controller of the circuit or alternatively and more preferred is that once the user has set the parameters for the time operation, these parameters are transmitted to the controller and at least temporarily stored in memory associated with the controller such that the controller can implement the instructions once the appropriate time is reached.

[0058] According to a preferred embodiment, information in relation to more than one circuit may be displayed on a single interface and controls may be provided in relation to each of the more than one circuit. This may allow control of more than one circuit from the same interface without the requirement to proceed through each interface separately to control respective circuits.

[0059] A login or authorisation process may be used to only allow authorised operators to operate the controller. Where provided, the login process may use login details that the operator has developed for another application or use. For example, the operator may use a Facebook or Twitter account login or similar or alternatively login details for an email system such as Gmail or Hotmail in order to access the system of the present invention. Normally, details of the operator login will be stored in a profile stored on the control unit and as a login request is received, the controller may ensure that the login details supplied match those of an authorised operator before allowing access to the system.

[0060] Normally, a login prompt is produced and displayed as a displayed image on the display of the personal computing device and including at least one action button.

[0061] Alternatively a relatively straightforward PIN process can be used, set by an operator such that anyone that has the PIN can operate the controller.

[0062] The software application of the present invention may also allows the system to be controlled from outside of the premises or over Wi-Fi. For example, a hub can be provided which is connected to a cloud system.

[0063] At least one receiver is associated with each of the at least one controllers in order to receive information and/or instructions from the transmitter. The receiver may include or be associated with a decoder in order to decode any information which may have been encoded before transmission. In other embodiments, encoding/decoding may be done within micro controller software.

[0064] Instructions received are typically then passed on to a microcontroller which is responsible for implementing the instructions. The microcontroller will typically control the switching hardware. The switching hardware may be provided in any form and may for example be physical switching hardware which interacts with each of the individual switches, preferably at the building switchboard level or alternatively, the switching hardware may be our include electronic switching hardware capable of engaging and disengaging one or more electric circuits according to the instructions.

[0065] The system of the present invention preferably controls the status of one or more electric circuits and in particular, whether the circuits are connected to a power supply or disconnected from a power supply as required. The controller will typically require set up and the electric circuits themselves may require some set up. Normally, more than one electric circuit will be provided in a particular premises and each electric circuit will typically have one or more electric devices connected thereto. Typically, in the setup of the system of the present invention, essential electric items will typically be connected to one or more circuits which will be designated as essential power supply circuits and the remainder of any electric devices in the premises will typically be connected to one or more electric circuits designated as non-essential electric circuits. Use of the present invention will then typically allow a user to disengage one or more of the non-essential electric circuits from the power supply in real time and on demand but to allow the essential power supply circuits to remain connected. The present invention may allow a user to selectively engage with disengage one or more circuits to which non-essential electric device(s) are connected or alternatively, the user may simply engage and disengage all of the non-essential electric circuits at the same time without affecting the essential power supply circuits.

[0066] As mentioned above, the switching hardware will typically operate at the premises switchboard level.

[0067] As an illustrative example, the switching hardware may include: a switching device; and a bypass switch for bypassing the present invention such that the particular circuit operates as normal. In some embodiments, the switching device may be hardwired to a node or controller.

[0068] The controller of the present invention will typically allow designation of circuits, will typically allow selection of one or more electric circuits for control and allow grouping of more than one electric circuits into one or more groups to allow actuation of groups of circuits.

[0069] As an illustrative example, the node may include one or more of: a PLC (Power Line Communications) coupling circuit for communicating with building circuits; a WIFI or Bluetooth module; transmitter associated with the node/controller for transmitting instructions, data and/or status updates from the display/user interface; receiver associated with the node/controller for receiving instructions from the display/user interface; CT (Current Transformer) for measuring energy use; protection circuits for protecting the node/controller from over heat, over current and/or general faults; auxiliary inputs for receiving digital instruction from external systems (e.g. security system); switches, buttons and/or indication LEDs; output to power and control the Power switch; a microcontroller for controlling; a programing port for updating firmware.

[0070] In a particularly preferred embodiment, the controller of the present invention will typically operate a primary control software application in order to receive and implement the instructions transmitted from the transmitter.

[0071] Any of the features described herein can be combined in any combination with any one or more of the other features described herein within the scope of the invention.

[0072] The reference to any prior art in this specification is not, and should not be taken as an acknowledgement or any form of suggestion that the prior art forms part of the common general knowledge.

[0092] DESCRIPTION OF EMBODIMENTS

[0093] According to a particularly preferred embodiment of the present invention, a nonessential circuit switch system is provided.

[0094] As illustrated schematically in Figures 1 and 2, the non-essential circuit switch system for a power supply of a building 10 of the preferred embodiment includes a control unit 11 including a set of user actuable buttons 13 to allow a user to control operation of the system and a transmitter 14 associated with the user interface to transmit instructions, a receiver unit 12 including a receiver 15 to receive instructions from the transmitter 14 of the control unit 11 and a controller 16 associated with the receiver 15 and operating control software to receive information from the receiver 15, and electrical power switching hardware associated with the building power supply, normally at the building switchboard 17 to switch one or more electrical circuits of the premises on and off according to instructions issued by the user via the actuable buttons 13.

[0095] At its core, the system of the present invention provides a user with a remote user interface used to switch (on, off) non-essential circuits in a premises when the appliances on those circuits are not needed or when people have left the building.

[0096] Generally, there are three main elements present in the system of the present invention, these elements typically including a user interface and transmitter provided on one element (control unit 11), a receiver and controller provided in a second element (receiver unit 12) and the switching hardware which is generally provided in association with the receiver unit 12 but as third element able to interact directly with the power switches 19 which connect and isolate circuits from the building power supply.

[0097] The user interface and transmitter element will normally be provided such that the user interface allows a user to control the system as well as to configure the system. Any type of user interface can be provided. For example, in the simple embodiment illustrated in Figure 1, the user interface may be provided as a simple wall mounted control unit 11 with one or more switches allowing control of circuits as required.

[0098] In one embodiment, the user interface and transmitter are provided as a wall mounted control unit 11 including at least one switch or panel of switches for user input of instructions to the control unit 11 to issue instructions to the controller 16. The control unit 11 may include an encoder 20 in order to encode instructions before being transmitted by the transmitter 14.

[0099] The control unit may be as a wall mounted control unit 11, typically adjacent a main entrance or exit door 21. Preferably, a wall mounted control unit 11 will have a wall plate, similar in size and shape to a conventional light switch. It is preferred that the wall plate be provided with touch sensitive buttons to allow operation of the system.

[00100] The control unit 11 may have any number of operating channels and can be single channel or multichannel. Instructions in relation to different circuits may be issued on different channels.

[00101] The control unit 11 typically includes at least one “on” button and an “off’ button. Pairs of buttons may be provided for each circuit or alternatively a single button can be provided with the button cycling between instruction to connect the circuit (on) and instructions to disconnect the circuit (off).

[00102] The controller 16 may also include a timer function. Use of the timer function will typically allow a user to activate or deactivate a timer functionality to allow the user to connect one or more circuits (on) and to disconnect one or more circuits (off) at one or more particular times.

[00103] The control unit 11 of the preferred embodiment will preferably include a wireless communication transmitter 14 to allow communication with the receiver 15. Bluetooth is a preferred method of wireless communication but any portion of the electromagnetic spectrum can be used. This will typically allow the control unit to operate as a remote control to issue instructions to the receiver 15 as required.

[00104] The wall plate control unit 11 according to a preferred embodiment will typically include a plastic or similar housing mounted relative to a wall surface. A forward face of the housing will typically have identified portions provided for switches allowing different functionality. Each of the switches will typically allow communication of control instructions to the controller to control the circuits. Each of the buttons will typically have a function identified thereon, typically using text.

[00105] Each of the switches will also typically have an associated light or similar indicator, preferably an LED, in order to indicate the status of the particular operation initiated by the switch. Typically, the preferred LED will indicate a first colour when initiated and indicate a second colour or be unlit when not activated. Typically, a single light will be provided for each switch.

[00106] Control of one or more circuits of the premises power supply utilising the system of the present invention can be directly applied through the user interaction with the switches on the preferred wall mounted control unit 11.

[00107] Preferably, the controller 16 is provided in relation to a structure or building or room within a building 21 and each circuit controllable thereby will normally be provided with the unique designation and/or channel provided for identification. This will allow a user to control each of the circuits individually and independently. There will typically also be provided the ability to control link more than one circuit together such that multiple circuits can be controlled by one “button”.

[00108] A receiver 15 is associated with the controller 16 in order to receive information and/or instructions from the transmitter 14. The receiver 15 may include or be associated with a decoder 22 in order to decode any information which may have been encoded before transmission.

[00109] Instructions received are typically then passed on to a microcontroller 16 which is responsible for implementing the instructions. The microcontroller 16 will typically control the switching hardware. The switching hardware may be provided in any form and may for example be physical switching hardware which interacts with each of the individual power switches 19, preferably at the building switchboard level or alternatively, the switching hardware may be or include electronic switching hardware capable of engaging and disengaging one or more electric circuits according to the instructions.

[00110] The system of the present invention preferably controls the status of one or more electric circuits and in particular, whether the circuits are connected to a power supply or disconnected from a power supply as required. The controller 16 will typically require set up and the electric circuits themselves may require some set up. Normally, more than one electric circuit will be provided in a particular premises and each electric circuit will typically have one or more electric devices connected thereto. Typically, in the setup of the system of the present invention, essential electric items will typically be connected to one or more circuits which will be designated as essential power supply circuits and the remainder of any electric devices in the premises will typically be connected to one or more electric circuits designated as non-essential electric circuits. Use of the present invention will then typically allow a user to disengage one or more of the non-essential electric circuits from the power supply in real time and on demand but to allow the essential power supply circuits to remain connected. The present invention may allow a user to selectively engage with disengage one or more circuits to which non-essential electric device(s) are connected or alternatively, the user may simply engage and disengage all of the non-essential electric circuits at the same time without affecting the essential power supply circuits.

[00111] As mentioned above, the switching hardware will typically operate at the premises switchboard level.

[00112] The controller of the present invention will typically allow designation of circuits, will typically allow selection of one or more electric circuits for control and allow grouping of more than one electric circuits into one or more groups to allow actuation of groups of circuits.

[0113] In a particularly preferred embodiment, the controller of the present invention will typically operate a primary control software application 23 in order to receive and implement the instructions transmitted from the transmitter 14.

[0114] Another preferred embodiment of the non-essential circuit switch system is schematically shown in Figure 18. The non-essential circuit switch system shown in Figure 18 substantially includes all of the features as described above in relation to the non-essential circuit switch system shown in Figure 1. However, includes a fourth element in the form of remote switching hardware 25.

[0115] As shown in Figure 18, the remote switching hardware is located between individual power sockets or outlets and a non-essential appliance, such as a toaster or kettle. The remote switching hardware receives instructions from the second element, e.g. node, to switch the kettle or toaster on or off. Advantageously, the toaster or kettle can be turned on or off without turning on or off the entire electrical circuit to which it is attached.

[0116] There are a number of variations through which the operation of the system of the present invention can be more clearly illustrated.

Variation 1 (Small Business): [0117] Often when ending the work day the staff or owner of a small business will have to run around and turn all the lights and appliances in the business off before exiting. This is to avoid large power bills and to extend the life of light bulbs & appliances plugged into the power sockets. This will also reduce the risk of a fire due to appliances being left on overnight or the weekend. The power points and light switches for all the appliances, display lights and general lights will often be located at different positions within the business and the staff / owner will have to run around at the end or beginning of each day turning everything on or off.

[0118] The system of the present invention allows the task of turning everything off or on at the end or beginning of the day to be done by the push of a button. In its simplest form, the system includes a switch connected to the lighting and power circuits of a building that is operated by a wireless remote panel. The remote panel can be located near the entry or exit of the business or wherever the business owner desires. There can be multiple wireless remote panels for multiple exits or entries. The base or receiver shall be mounted either in the electrical switchboard or adjacent to it.

[0119] The wireless remote panel uses a standard decoding chip (RF600E - RF Solutions) to send information via a transmitter (standard 315MHZ, 433MHZ, AM, ASK, AM, FM, etc.). The transmitter has a range of 100-200m. The information sent is 1-4 different button options (similar to a garage remote). The information is then received by the receiver (standard 315MHZ, 433MHZ, AM, ASK, AM, FM, etc.) and passed on to the decoder (RF600D - RF Solutions). After the decoder decodes the information it is then passed on as binary information to a microcontroller (PICAXE14M2 - Picaxe). The microcontroller then manages the information (binary inputs) according to its pre-written software program and applies the appropriate (on or off). The output of the microcontroller is applied to a driving transistor which then is used to switch the power relays. The power relays act as a switch for the buildings power and lighting circuits. The building circuits are connected to the NC (Normally Closed) contacts of the power relays. When the user activates the Power Shredder the power relay energises and changes state opening the NC contacts and the buildings circuits.

Variation 2 (Large Business, Factory or School): [0120] Often when ending the work or school day the staff or management at a factory or school will run around checking and turning all the lights and appliances off before arming the alarm and exiting for the day or weekend. This is to avoid large power bills and to extend the life of light bulbs, tools & appliances plugged into the power sockets. This will also reduce the risk of a fire due to appliances being left on overnight & over the weekend. The GPO’s (General Power Outlets), power circuits and light switches for all the appliances, tools, processes and lights will often be located at different positions, rooms & buildings within the business. The staff or management will have to run around at the end or beginning of each day or week checking and turning everything on or off and checking that everything has been locked up before arming the alarm.

[0121] The system of the present invention allows the task of turning everything off or on at the end or beginning of the day to be done by the push of a button or by a pre-determined timer. In its simplest form it is a button that is connected to the lighting and power circuits of a building, school or factor, etc. that is operated by a wireless remote panel. The remote panels can be located near the entry or exit of the different rooms or buildings in the business or wherever the business owner desires. There can be multiple wireless remote panels for multiple exits or entries. The base or receiver shall be mounted either in the electrical switchboards or adjacent to them.

[0122] The wireless remote panel’s use a standard encoding chip or method to send information wirelessly (315MHZ, 433MHZ, AM, ASK, AM, FM, 2.4GHZ, Wi-Fi etc.) via a transmitter. The transmitter has a range of 100-400m. The information is from 1 of 4 different buttons (on, off, timer, spare for future development). The information is then received by the receiver (315MHZ, 433MHZ, AM, ASK, AM, FM, 2.4GHZ, Wi-Fi etc.) and passed on to the decoder. After the decoder decodes the information it is then passed on to a microcontroller which organises the information to produce the appropriate output (on or off). The output of the microcontroller is applied to a driving transistor array which then is used to switch the power switch (power relay, triac’s contactors, SSR, etc. The power switch then switches the buildings lighting and power circuits.

Receiver Programing Screen [0123] The owner of a business may want the different buildings to turn on or off automatically at a pre-set time each day rather than pushing a button. A programing screen can be added to the receiver’s microcontroller. This can be used to input the on or off times desired by the operator.

Mini Receivers (plug pack size) [0124] Sometimes there may be essential equipment (fridge, security, server, etc.) mixed with non-essential equipment (printer, coffee machine, microwave, etc.) on the same circuits. In this instance a mini receivers (similar size to a double adaptor) can be used to switch the power off or on. The mini receivers are plugged into the individual power outlets on that circuit and are linked into the main receiver wirelessly. Essentially they are a scaled down version of the main receiver. They can be used to switch the non-essential equipment on or off while leaving essential equipment left unaffected while being on the same circuit.

Variation 3 (House “medium class”): [0125] Electricity prices continue to rise. When leaving their home people will go around checking and switching appliances & lights off to avoid wasting power. Often people will be running late, pressed for time and end up leaving appliances & lights switched on. This increases their electricity bill.

[0126] The system of the present invention allows the task of turning everything off or on when leaving your home to be done by the push of a button. In its simplest form it is a remote switch connected to the lighting and power circuits of a home that turns all the non-essential electrical circuits off or on at the push of a button.

[0127] The wireless remote panel uses a standard decoding chip (RF600E - RF Solutions) to send information via a transmitter (standard 315MHZ, 433MHZ, AM, ASK, AM, FM, etc.). The transmitter has a range of 100-200m. The information sent is 1-4 different button options (similar to a garage remote). The information is then received by the receiver (standard 315MHZ, 433MHZ, AM, ASK, AM, FM, 2.4GHZ, Wi-Fi, etc.) and passed on to the decoder (RF600D -RF Solutions). After the decoder decodes the information it is then passed on as binary information to a microcontroller (PICAXE14M2 - Picaxe). The microcontroller then manages the information (binary inputs) according to its pre-written software program and applies the appropriate (on or off). The output of the microcontroller is applied to a driving transistor which then is used to switch the power relays. The power relays act as a switch for the buildings power and lighting circuits. The building circuits are connected to the NC (Normally Closed) contacts of the power relays.

[0128] When the remote panel buttons are pressed the power relays operate, opening or closing the connected circuits of the home.

Variation 4: [0129] Often when ending the work day the staff, occupants or owner of a building whether it be home, business, school, factory, etc will have to run around and turn all the lights and appliances in the building off before exiting. This is to avoid large power bills and to extend the life of light bulbs & appliances plugged into the power sockets. This will also reduce the risk of a fire due to appliances being left on overnight or the weekend. The power points and light switches for all the appliances, display lights and general lights will often be located at different positions within the building and the staff, occupants or owner will have to run around at the end or beginning of each day turning everything on or off. Often when people leave their house they will try to switch most of the obvious appliances, lights, fans & air conditioners off to avoid unnecessary power expense and reduce the risk of a fire or even to extend the life of an appliance or light bulbs.

[0130] The system of the present invention allows the task of turning everything off or on at the end or beginning of the day or when exiting a building to be done by the push of a button, timer, app or linked in with the buildings security system. In its simplest form, the system includes a switch connected to the lighting and power circuits of a building that is operated by a wireless user interface or existing security system interface. The user interface can be located near the entry or exit of the building or wherever the operant desires. There can be multiple wireless remote panels, controllers for multiple exits or entries and multiple buildings within a facility (eg a school or factory). They can be set up as with master or slave modules for coordination at a multiple building installation. The node or controller is mounted either in the electrical switchboard or adjacent to it. The switching devices are mounted inside the switchboard and connected directly after the circuit breakers.

[0131] The wireless user interface uses standard wireless transmitter and receiver modules to send information via a transmitter (standard 315MHZ, 433MHZ, AM, ASK, FM, etc.). The transmitter has a range of 50-200m. The information sent is encoded via a microcontroller using software. The information is then received by the receiver (standard 315MHZ, 433MHZ, AM, ASK, FM, etc.) and passed on to a microcontroller for decoding. The microcontroller then manages the information according to its pre-written software program and applies the appropriate output (on or off). The output of the microcontroller is applied to a driving FET (Field Effect Transistor) which then is used to switch the power triacs via optocouplers. The optoeouplers are used for separation from dangerous alternating current. The power triac’s act as a switch for the buildings power and lighting circuits (alternately relays or contactors could be used). The building circuits are connected as NC (Normally Closed). When the user activates the invention the power triac’s changes state opening the circuits of the building. If an occupant of a building decides that what to change a circuit from non-essential back to essential a built in bypass switch for each of the individual building circuits may be used.

[0132] In the instance where there is a circuit with essential and non-essential appliances on it, a remote switch can be used. The remote switch may be a small plug in device that is mounted between the GPO and the non-essential appliance. Remote switching is then controlled by a node. Instructions are communicated from the node to the remote switch via power line communications.

[0133] A user interface is provided as a HMI (Human Machine Interface) between the user and the system. In this variation the user interface is a LCD display with control push buttons and is generally mounted near an entry or exit of a building. The structure the LCD display is a menu like structure providing a selection menu and selection capability via push buttons.

[0134] A user may achieve one or more of the following through the user interface: i. View the building or facility’s current power usage; ii. View the building or facilities historical power usage; iii. View the $ savings from the activating the invention; iv. View the historical $ savings from activating the invention; v. View and set the current time; vi. Program the timer (invention activation timer for on/off time); vii. View the status of the invention; viii. View status of other nodes (in the instance where there is master and slave nodes in the facility); ix. View current power usage of other nodes (in the instance where there is master and slave nodes in the facility); x. View historical power usage of other nodes (in the instance where there is master and slave nodes in the facility); xi. View current $ saved by using the invention of other nodes (in the instance where there is master and slave nodes in the facility); xii. View historical $ saved by using the invention of other nodes (in the instance where there is master and slave nodes in the facility); xiii. Selecting different tariff’s.

[0135] An alternative, more detailed embodiment is illustrated in Figures 13 to 17. The system illustrated in Figures 13 to 17 is a non-essential circuit switch system for controlling supply and activation of circuits for a number of buildings each of which includes a slave node 50 but in which one of the buildings is designated as a master node 51 to control not only the building of the master node 51 but also the other buildings having slave nodes 50. In the embodiment illustrated in Figure 13, Building 1 is designated as the master node and Buildings 2 to 5 are each designated as a slave node which are ultimately controlled by the master node 51. As illustrated, the master node is connected to each of the individual slave nodes by a PLC (Power Line Communications) umbilical but this connection may be a wireless connection.

[0136] The node in each building includes a display, metering and HMI button interface to allow a user to control operation of the system. In buildings designated as slave nodes 50, the display, metering and HMI button interface 2 will typically accept input and transmit the input to the slave node controller in that building and the slave node controller will typically communicate with the master node 51. Alternatively, instructions can be input at the master node 51 and then flow through to each of the slave nodes 50.

[0137] Each of the nodes is associated with a transmitter to transmit instructions from the user interface 52 to and from the respective slave node 50 and ultimately to and from the master node 51.

[0138] Each node will also include a receiver to receive instructions from associated transmitters. Generally therefore, each node will typically include both a receiver and a transmitter.

[0139] Each node preferably operates control software to receive information from the master node and sends appropriate instructions to an electrical power switching device 53 associated with the electrical system of the building to switch one or more electrical circuits of the building on and off according to instructions issued by the user via the user interface 52 but the system illustrated can also control devices associated with individual power socket or outlets 54.

[0140] The system illustrated in Figure 13 also includes a smart phone operating a software application allowing the software application to be used to issue instructions to the node.

[0141] A preferred configuration of the node controller is illustrated in Figure 14, a preferred configuration of the display, metering and HMI button interface is illustrated in Figure 15, a preferred configuration of power socket device is illustrated in Figure 16 and a preferred configuration of an electrical power switching device associated with the electrical system of the building is illustrated in Figure 17.
