  • a child-friendly embodiment may allow a child to have a display in his or her bedroom to monitor their own personal contribution to household consumption. The child can therefore readily appreciate the effects of, say, leaving their television on standby or playing a games console for a considerable length of time. Acceptance of such a display in a child's bedroom can be enhanced by provision of exchangeable covers, and by providing visual incentives such as "smiley” and "frowny” faces dependent on the consumption habits of the child.
  • the system can aid in the fair allocation of bills. For example, electricity consumption in student accommodation can be monitored on a room by room basis and each student charged for their own usage. In an analogous way, companies sharing premises can be accountable for their own usage and bills split appropriately.
  • scales on any of the above displays could be coloured so as to identify the relative resource, e.g. green for gas, blue for water and yellow for electricity. Said scales could also toggle to a warning colour, say red, or vary in intensity dependent on the extent of the consumption, e.g. thresholds being exceeded.
  • colouration of the indicators may provide a quick indication of whether consumption is low, medium or high (respectively) .
  • a gauge of the consumption can be made and acted upon. Plus, as with the visual incentives proposed above for a child-friendly embodiment, it will be easier for a child to interpret "good", “normal” or “bad” energy consumption on the basis of this colour scheme.
  • another colour of indicator for example blue, may be used to indicate energy coming from a renewable source, whether it be from microgeneration or energy provided under a so-called “green” tariff. The blue indicator may visually offset the traffic light-like green, amber and red proposed above.
  • the displays may also be adapted to present information relating to the generation of resources by, for example, rotary wind turbines or solar panels, and indicate how this affects the net consumption (or carbon footprint) . This may be indicated by accommodating a negative scale on each of the displays which would display a contribution of energy, and provide a visual indication of how microgeneration can be used to offset domestic consumption.

  • the scales 64 could be replaced with three single red LEDs; the system having been configured to illuminate the single red LEDs when the rate of consumption or the aggregated consumption of any or all resources reaches or exceeds a threshold value. It is anticipated that all of the conduits that a user wishes to monitor may not be located in such proximity so as to allow one transmitter to be connected to them all.
  • Figure 14 illustrates an example where a separate transmitter 65,66,67 is provided for each of the transducers 54,55,56, which then allows for more convenient installation of the system. Furthermore, an alternative display unit 68 is illustrated which presents information regarding consumption of gas, water and electricity by means of a single LED 69,70,71 corresponding to each resource.
  • a threshold value can be set for each utility, whereby consumption of a utility over the threshold results in illumination of the respective LED.
  • the threshold may be set at a value corresponding to a normal consumption of a particular resource. However, it may also be set to a zero level such that any consumption results in illumination of the respective LED. In use, the attention of a person leaving their home might be drawn to an LED indicating that a source of water is running. If this is unexpected, they may realise that a tap has been left open.
  • An intelligent aspect is also envisaged whereby the system is aware that a particular appliance (say, a washing machine) is in operation and the expected water consumption known. In this case, consumption over and above this expected value might cause an LED to be illuminated alerting the user that another source of water must be running.
  • a particular appliance say, a washing machine
  • a button may be depressed on the display whereby monitoring consumption continues, but a separate monitoring takes place of consumption after the button press.
  • a user may wish to determine the resources consumed by their washing machine. Pressing a button on the display then establishes a baseline consumption of each resource, and presents only information relating to consumption over and above this baseline. In this way, the amounts of water, electricity, gas and the like consumed during a washing cycle can be monitored. Any appliance can be monitored in the same way, and this may also aid in diagnosing whether an appliance is consuming more resources than expected. This may have a particular application in monitoring the power consumption of air conditioning units which are known to be demanding on resources and being able to readily appreciate this will allow users to use such, units in a more resource-conscious way.
  • FIG 15 illustrates a further alternative embodiment in which a resource monitoring system is incorporated into a vehicle 71.
  • Electricity 72 and fuel 73 monitoring transducers may be fitted in the factory during manufacture of the vehicle or, in this case, be clamp-on transducers which are retro-fitted proximal to the car battery 74 and to the fuel line 75 in the under-bonnet space of an existing vehicle.
  • the transducers 72,73 monitor consumption and tranmsit corresponding signals indicative of this consumption to an in-car display unit 76, which in this case displays two scales 77,78 against which electrical consumption and fuel consumption are gauged.
  • This display 76 and it's proximity to the steering wheel 79 and other dashboard displays enables a driver of the car to quickly gauge their consumption against a target consumption and to visually appreciate how differing driving habits can affect that consumption. It is envisaged that this embodiment
  • Transducers corresponding to particular energy sources may simply be retrofitted and subsequently detected by the in-car display unit. Furthermore, energy generated (for example by braking) can be visually offset against consumption.
  • Figure 16 illustrates a teaching aid 80 which employs a display 81 similar to those discussed above and is capable of demonstrating consumption of energy by various items.
  • a mains socket 82 is provided to which an appliance, for example a hair dryer, can be connected.
  • an appliance for example a hair dryer
  • the energy consumption by the appliance is determined and displayed on the display 81. In this way, the consumption of that appliance can be demonstrated, in particular to children, in a readily understandable way.
  • Light source sockets 83, 84 and 85 are also provided, corresponding to a fluorescent tube 86/ an incandescent bulb 87, and an energy-saving lightbulb .88. By switching each of these light sources on and off, and watching the energy consumption of each as monitored and displayed on the display 81, a useful tool to illustrate the benefits of particular light sources is achieved.
  • Switches 89, 90, 91 may represent a fridge, a freezer and a washing machine for example. Alternatively, the switches may simulate a washing machine at varying temperatures of operation, e.g. 30°, 40° and 60°.
  • a simulated thermostat 92 may be used to illustrate the difference in energy consumption dependent on the target temperature of a central heating system.
  • Relative consumption of resources by different appliances and light sources etc. can be a useful tool in educating people.
  • the benefits of (by way of example) using one particular kind of bulb over another, or one particular rating of fridge over another can be easily understood. This is achieved by the simple and clear representation of consumption provided by the display.
  • the system of the present invention is therefore seen not only as a tool for allowing consumers to better understand and improve their overall energy consumption, but as a tool to educate children (the consumers of the future) at an early age.
  • the present invention provides a way for a user to quickly determine their level of usage of a number of utilities. They may then act upon this information to reduce their consumption resulting not only in a cost saving to themselves but a reduced environmental impact.
  • a further advantage of aspects of the present invention is that the system can be employed in a number of different locations such that utility consumption can be broken down and assessed in, for example, different areas in the home.
  • the present invention will allow a user to be able to monitor their utility consumption with ease and thereby use said utilities in a more cost effective and environmentally conscious way.
  • the information is presented in such a way that a user can quickly determine the nature of consumption of the utilities, and identify any unexpected usage.
  • Target amounts may be set for consumption, and the display could present visual and/or audible alarms should consumption exceed those target amounts.
  • the system may "learn" over a period of time and determine expected usage levels (which may of course vary during the year) . Usage contrary to these expected values may then provide alerts to the user that they are either over-consuming or consuming less than usual. This also facilitates a safety feature wherein excessive consumption can be brought to the attention of a user. For example, if a low rate of consumption is expected at a particular time of the day (or of the year) and a high rate is measured this can be brought to the attention of the user. It may be indicative, therefore, of an appliance being left on by mistake (e.g.
  • a user exiting their home may be alerted to the fact that they have left, for example, an oven hob switched on.
  • a number of transducers may be located at varying locations throughout. This will allow monitoring of consumption in particular areas in the building but also provide a means of locating a fault, such as a gas leak (or blockage) which is indicated by an excessive (or reduction in) consumption of that resource.
  • a reduction in the rate of consumption over a period in which a higher rate of consumption is expected may be indicative of a reduction in activity. This may alert people to the possibility that someone, for example an elderly relative, has changed their habits which may be due to reduced mobility because of an accident or illness.
  • a user's attention may be brought to irregularities in consumption rates by SMS, email, pre- recorded telephone message or the like.

  • the system of the present invention may be fitted to existing utilities and to their metering equipment. It may also be fitted in new build houses, offices or industrial premises, or retro-fitted in existing properties. In addition, it can be used to monitor production of electricity, for example by wind turbine, and to appreciate how microgeneration can affect domestic utility costs.
  • Calibration also enables the same system to be incorporated into a wide variety of environments, from single bedroom flats to multi-storey offices, from student accommodation to industrial factories.
  • the calibration provides a means to tailor the displays, any thresholds, targets or maximum values and so on for the specific requirements of the situation.
  • the same display is therefore suitable for monitoring the consumption of a small household as well as a large, heavily resource dependent, production plant.
  • the exemplary weighting table discussed above may be tailored for domestic appliances, industrial machinery, or any manner of equipment for which it is desirable to monitor the consumption of resources.
  • Monitoring the consumption of resources may assist in the production of bills .
  • Present billing typically estimates consumption over a year and produces monthly or quarterly bills accordingly. At the end of the 12 month billing cycle the actual consumption is determined and there will usually be a credit or a deficit against which further estimates and a reduced or increased monthly bill is calculated.
  • the present invention may allow utility companies to provide bills tailored to the actual consumption by a user by using information from the system. This information can be conveyed to the company over wired or wireless communication devices, over the internet or other telecommunication system.
  • the present invention may therefore also address some of the problems associated with the provision of oil and LPG. Consumers and providers have little indication of their usage of such utilities, and might only find out when the utility runs out. This can be of great inconvenience to rural consumers who may have difficulty accessing alternative resources in the meantime.
  • the present invention also allows such consumers to monitor consumption of ' those utilities and thereby act accordingly when supplies are running low. SeIf- regulation is therefore enabled for these resources, and billing can also be simplified.
  • the system of present invention is also provided with a range of support services that may be provided on-line. This may include technical support, information on ways of calibrating the device, a shop where related products such as decorative covers can be bought, information on energy efficiency, the availability of grants and information on renewable energy.

  • information and links may be provided to allow users to offset their carbon emissions by placing corresponding orders to plant trees.
  • reduced consumption of resources may be rewarded by the allocation or granting of so-called carbon credits which may be collected and used to pay for the carbon emissions created as a result of particular activities; e.g. going on holiday or commuting to work.
  • a connection to a server may be provided so as to allow updated tariff information to be relayed to the processor. This would allow for any changes in billing rates to be reflected accurately in the display.

Abstract

L'invention concerne un système de surveillance de consommation de ressources de services publics, telles que gaz, LPG, pétrole, électricité et eau, et d'affichage de ces informations de manière à les interpréter facilement. La consommation des ressources est surveillée et traitée avant d'être affichée sur une interface utilisateur. Le traitement des informations permet de déterminer des valeurs de consommation seuil et des valeurs de consommation maximum et d'obtenir des détails tarifaires. Dans un mode de réalisation pris en exemple, les consommations de gaz, d'électricité et d'eau sont affichées simultanément sur trois échelles de couleurs variables indiquant la quantité de consommation. Des alertes peuvent informer un utilisateur lorsque les seuils sont dépassés ou lorsque les habitudes de consommation changent. Un auxiliaire d'apprentissage utilisant ledit système permet d'assimiler facilement les effets des divers appareils sur la consommation de services publics.
