Brief description of the drawings
Reference will now be made, by way of example, to the accompanying drawings, in which: -Figure 1 is a schematic representation of a system, in accordance with an embodiment of the invention, given by
way of example,
-Figure 2 is a schematic representation of use of the system according to the invention to monitor energy data in a household, given by way of example,
Detailed description of the preferred embodiments
Figure 1 is a schematic representation of a system for monitoring and processing data relating the energy usage in locations.
The system comprises a remote database 100 for receiving and analysing energy usage data for the locations and an energy-monitor-unit 110 for collecting energy usage data in a first location. The remote database 100 is further connected to further energy-monitor-units 120, 130 and 140, each for collecting energy usage data in a further location. In figure 1, for practical reasons, only three further energy-monitor-units 120, 130 and are shown. It should be understood that in practise the remote database 100 will be connected to a large numbers of energy-monitor-units in order to be able to receive and analyse energy usage data for a large number of locations.
In order to explain the functioning of the energy-monitor-units, reference will be made to the energy-monitor-unit 110. It should be understood that the further energy-monitor-units 120, 130 and 140 will have a similar set-up.
The energy-monitor-unit 110 comprises a sensor 201 for sensing the energy usage of a device in a location. This sensor 201 is provided with a first communication module for sending energy usage data for the device to a processor 200.
The processor 200 has a first communication module for receiving the data produced by the sensor 201. The first communication module uses, for instance, Zigbee (IEEE 802.15.4). The sensor 201 for measuring the energy usage of a device can be adapted to sense the electrical energy consumption of an electrical device. Alternatively, the sensor 201 can be adapted to measure the gas-consumption of, for instance, a boiler or a cooking device.
It will be understood that in the system according to figure 1 any preferred number of sensors 201 can be used to produce energy usage data for any preferred number of devices in a location.
As shown in figure 1, the energy-monitor-unit 110 further comprises a temperature sensor 202 in order to measure the temperature in the location. This temperature sensor 202 is also provided with a first communication module for sending data relating to the temperature in the location to the processor 200. A further temperature sensor 202 (in case relevant) may be used to produce date relating the outside temperature.
The data relating the temperature inside and outside the location can be very useful to improve the analysis of the energy usage in a particular location.
As shown in figure 1 the energy-monitor-unit 110 further comprises a total energy sensor 203 in order to measure the total amount of energy used in the location. This total energy sensor 203 could, for instance, be installed in the meter cupboard of a location. This total energy sensor 203 is also provided with a first communication module for sending data relating to the total energy consumption in the location to the processor 200.
The processor 200 will receive the data from the several sensors 201, 202 and 203. Those data will be processed on the processor 200. In order to display the data for visual inspection of the data, the processor 200 is provided with a connection to connect the processor 200 to a display 300.
This display 300 is for instance a television. The connection can include a SCART interface to enable easy connection of the processor 200 to a standard television.
Once the data is displayed on the display 300, a user can visually inspect the data and send instructions to the processor 200 using a remote control 310 which is able to communicate with the display 300.
The processor 200 is also provided with a second communication module in order to allow communication with the remote database 100. The remote database 100 is provided with a similar second communication module. These second communication modules allow for bi-directional wireless communication between the processor 200 and the remote database 100. The second communication modules, for instance, use a GPRS communication method.
The second communications modules allow the processor 200 to transfer energy usage data relating to a specific location to the remote database 100. On the remote database 100 the energy usage data received from all energy-monitor-units 110, 120, 130 and 140 can be received, stored, processed and monitored.
A first data-process step that can be carried out on the remote database is to compare the energy usage data received from the different energy-monitor-units 110, 120, 130 and 140 with each other in order to identify trends and in order to calculate, for instance, averages.
The remote database 100 is connected to the Internet, schematically indicated with number 400. A second data-process step that can be carried out on the remote database 100 is to compare energy usage data received from the different energy-monitor-units 110, 120, 130 and 140 with information available on the Internet.
The detailed functioning of the system according to figure 1 will be described with reference to figure 2.
Figure 2 is a schematic representation of a possible use of the system according to the invention to monitor energy usage data in a household.
A first sensor 201 for measuring the energy usage is attached to the power line of a refrigerator 10 for measuring the electrical energy consumption of the refrigerator 10. A second sensor 201 is attached to the power line of a lamp 20 for measuring the electrical energy consumption of the lamp 20. A third sensor 201 is attached to the gas boiler 30 for measuring the gas consumption of the boiler 30.
In the household a temperature sensor 202 is installed in order to measure the temperature inside the location. It is possible to add a further temperature sensor 202 in order to measure the outside temperature.
A total energy sensor 203 is installed in the meter cupboard 40 in order to measure the total amount of energy used in the household.
The sensors 201, 202 and 203 send the data on energy usage and the temperatures to the processor 200. The processor 200 receives, coordinates and processes data feeds from the sensors 201, 202 and 203.
An on-board CPU performs the data processing. The processor 200 will have an internal clock in order to allow the processor to analyze the date and time of the energy usage in the household.
The devices 200, 201, 202 and 203 use Zigbee low power chips to communicate with each other. It should be understood that any other communication means adapted for short data transfer could be used, such as 802.11 Wifi or Bluetooth.
The sensors 201, 202 and 202 are provided with an on-board Zig bee chip which receives data and sends that data to the processor 200. The energy usage data is gathered through the use of simple low cost electronic components, performing current sensing.
The sensors 201, 202 and 202 are also provided with an on-board flash memory for locally storing data, for instance the data generated during the last 24 hours, to cater for any possible faults. Additionally, the sensors 201, 202 and 202 can be provided with modules to gather the status (on/off) of the household devices 10,20,30 they are monitoring. A battery may be used in order to power the sensors 201, 202 and 203.
The temperature sensor 202 is further provided with a thermocouple in order to sense the temperature.
The processor 200 is powered from the mains voltage. The processor 200 is provided with a SCART interface. This allows the processor 200 to be plugged into the television 300 and to be installed without requesting space and without forming a non-esthetical element in the location where the system is used. That means that once the processor is installed, the processor 200 is relatively invisible.
The processor 200 is provided with a software tool that provides a graphical user interface (GUI) onto the screen of the television using the PAL standard (Europe) or the NTSC standard (USA).
The use of the graphical user interface allows the energy usage data to be visually inspected in order to allow non-technically trained, home users to understand and review their own energy usage data. The better the user understands his own energy consumption, the easier it will be to help the user to change behavior in order to reduce energy consumption.
An onboard CPU of the processor 200 performs the data processing of the data generated by the sensors 201, 202 and 203 and sends it to an on-board GPRS chip. This GPRS chip is used to send the data to a remote database 100. To cater for any potential faults, the processor 200 has 100 MB of local storage.
The remote database 100 will receive usage date for a large number of locations. All this data can be forwarded to energy providers, such as electricity providers, in order to improve their knowledge of the energy use of their clients. The same information can be forwarded to Governmental organizations for monitoring and analyzing the data on energy usage in a region or country.
On the remote database 100 the energy usage data received from the different locations can be compared with each other in order to identify trends, averages, etc. Alternatively, the remote database 100 can compare energy usage data received from the different locations with information available on the Internet 400.
Since the remote database 100 and processor 200 are connected by means of bi-directional communication modules, the remote database can send feedback to the processor 200, for instance feedback based on the data received from the processor 200.
This feedback can contain suggestions and tips to improve the energy usage in a location. The source of the information can be an energy supplier, a governmental organization or it can be produced by the remote database 100 based on the results of the analysis of all energy usage data received by the remote database 100.
A possible use of the bi-directional communication between the processor and the remote database 100 is to offer a home-user the possibility to select an energy provider.
For this purpose the remote database 100 will receive the energy usage data from the processor 200. The remote database 100 can analyze the data and establish a user-profile for the energy consumption for this particular user. The remote database 100 can then compare the user-profile with offers from several energy providers. Once the remote database has completed the selection of information the remote database will send the information to the processor 200. Once the information is received on the processor 200, the processor 200 will display the information on the television screen 300 in order to allow the user to review the information. The user can provide his feedback, for instance the choice of a new energy provider, using the remote control 310 of his television. Via the processor 200 the user's feedback will be forwarded to the remote database 100 and onwards in order to make the requested changes.
As shown above the bi-directional communication between the processor and the remote database 200 provides a back channel, allowing third parties to send information to a user, based on the energy usage data produced in the residence or business site of the user.
In order to improve the communication between the remote database 100 and the processor 200, the second communications modules of the devices should allow for so called "trickle down" or low bandwidth, overnight data transfer. This allows videos and other digital presentations to be downloaded on the processor 200, for instance, during the night.
The information can be accessed by the user at a time of their choosing.
The present invention has been described with reference to both hardware and software elements. It will be appreciated that the system and the method could be implemented solely in hardware, solely in software or any combination thereof.
It will be appreciated that this invention may be varied in many different way and still remain within the intended scope and spirit of the invention.
