Abstract

The resource metering system comprises: an end-point device (25) consuming a resource, in particular for usage in a building (2) or in an outdoor lighting system, said device comprising a detection unit that produces status information and an indicator of usefulness; a smart meter (20) comprising: a communication circuitry provided with an interface adapted for receiving from said device status information and said indicator of usefulness; a metrology device connected to a medium (17) that provides the resource to said device; and a control circuitry connected to the metrology device for collecting resource consumption data, the control circuitry being connected to the communication circuitry and adapted to produce monitoring data to be securely transmitted to a server (10) after processing the status information and said indicator. Monitoring data are used when determining consumption tariffs, so as to encourage energy efficient usage of the device.

Claims

1. A method for billing a utility customer using a resource metering system in communication with a server, a smart meter, and an end-point device consuming a resource, the method comprising the steps of:

pairing the smart meter with the end-point device using power line communication,

producing, in a detection unit, data about the end-point device, said data including status information and at least one indicator of usefulness, wherein the status information includes a power reading and the at least one indicator of usefulness includes a presence sensor reading;

transmitting, by the end-point device, the data to the smart meter;

in the smart meter,

filtering power line communication signals between the smart meter and the end-point device to enable a secure pairing of the smart meter and the end-point device;

communicating with the server using communication circuitry via a first interface and communicating with the end-point device using the communication circuitry via a second interface, wherein the second interface receives status information from the end-point device and at least one indicator of usefulness of the end-point device, and the first interface transmitting the data to the server;

determining a quality level of resource consumption based on the power reading and presence sensor reading;

providing, using a metrology device connected to a medium, the resource to the end-point device;

collecting, using a control circuitry connected to the metrology device, resource consumption data representative an amount of resource consumed by the end-point device, the control circuitry being connected to the communication circuitry and produces monitoring data that is transmitted to the server after processing the status information and said indicator of usefulness; and

generating, using a processor, a warning indicator to a customer that reflects energy use associated with resource consumption and the quality level of resource consumption for the end-point device, wherein the warning indicator relates to spoiled energy and/or an amount of spoiled energy consumed in association with a date and a time; and

modifying a resource consumption price of the spoiled energy.

2. The method of claim 1, wherein the monitoring data transmitted to the server by said smart meter, represents data about usefulness of the resource consumed for the end-point device.

3. The method of claim 1, wherein said indicator of usefulness of the end-point device and corresponding status information are processed by the smart meter to determine if the end-point device is used in a resource saving manner.

4. The method of claim 1, wherein resource consumption rate characteristics and time information about the end-point device are used for estimation of resource consumption related to said end-point device.

5. The method of claim 1, wherein the end-point device is associated with a first priority and a second end-point device is associated with a second priority, a control signal from the server being received by the smart meter and converted into at least one of:

a resource consumption reduction recommendation, and

a resource consumption reduction command,

for reducing resource consumption of the second end-point device having the second priority.

6. The method of claim 5, wherein a hierarchy between the first and the second priority is dependent on the monitoring data.

7. The method of claim 1, wherein status information and said indicator of usefulness are transmitted to the communication circuitry of the smart meter by a communication module of the end-point device, signals transmitted between the communication module and the communication circuitry includes identification information, so as to ensure correct billing to the utility customer.

8. The method of claim 1, further using said indicator of usefulness to determine that the resource is consumed in excess for the end-point device.

9. The method of claim 8, including notifying a consumer, by the first or second interface of the smart meter or the end-point device, of the amount of spoiled energy consumed.

10. The method of claim 1, wherein a report session is started between the end-point device and the smart meter after transmission by the end-point device to the smart meter of data reflecting a capability to report usefulness.

11. The method of claim 1, wherein the end-point device is powered when a response from the server in reply to a request from the smart meter is received by the smart meter, said request being automatically transmitted after a command input of a user on an interface of the end-point device.

12. The method of claim 1, wherein the metering system includes a plurality of end-point devices and each end-point device is associated with different customers, wherein each end-point device is respectively interfaced with the communication circuitry of the smart meter, distinct identification information being used for the different customers for communication with the smart meter, whereby the server associates only one of said different customers to the monitoring data related to one end-point device of the plurality of end-point devices.

14. The method of claim 1, wherein the determination of the quality level of resource consumption for the end-point device includes providing information related to the resource consumption price of the spoiled energy.

13. A customer billing system for use by a utility company, the system comprising:

a resource metering system in communication with a server, the resource metering system comprising;

a smart meter;

an end-point device consuming a resource, the end-point device comprising;

a detection unit produces data about the end-point device, said data including status information and at least one indicator of usefulness, wherein the status information includes a power reading and the at least one indicator of usefulness includes a presence sensor reading; and

a power line communication module for transmitting to said smart meter data produced by the detection unit per power line communication;

the smart meter comprising;

a filter to filter power line communication signals between the smart meter and the end-point device to enable a secure pairing of the smart meter and the end-point device;

a communication circuitry comprising a first interface for interfacing with the server and a second interface for interfacing with said end-point device, the second interface receiving from said end-point device status information and the at least one indicator of usefulness of said end-point device, and the first interface transmitting data to the server;

a metrology device connected to a medium that provides the resource to the end-point device; and

a control circuitry connected to the metrology device for collecting resource consumption data representative of an amount of resource consumed by the end-point device, the control circuitry being connected to the communication circuitry and to produce monitoring that is transmitted to the server after processing the status information and said indicator of usefulness; and

a processor for determining a quality level of resource consumption based on the power reading and presence sensor reading, and generating a warning indicator to a customer that reflects energy use associated with resource consumption and a representative of a quality level of resource consumption for the end-point device, wherein the warning indicator relates to spoiled energy and/or an amount of spoiled energy consumed in association with a date and a time and modifying a resource consumption price of the spoiled energy.
