Abstract

The present invention relates to a system for estimating the individual water consumption of a plurality of devices supplied by the secondary fluid distribution network of a user. The system comprises a sleeve able to be fitted around the supply pipe of the secondary network and comprises an electromechanical sensor placed against the outside wall of the supply pipe, and a processor for analyzing the signals delivered by the electromechanical sensor with a view to extracting information characterizing the individual consumption of the devices supplied by the secondary network.

Claims

1-11. -11. (canceled)

12. A system for estimating an individual water consumption of a plurality of devices supplied by a secondary fluid distribution network of a user, comprising:

a sleeve configured to be fitted around a supply pipe of said secondary network said sleeve comprising an electromechanical sensor placed against an outside wall of said supply pipe, and

a processor for analyzing the signals delivered by said electromechanical sensor with a view to extracting information characterizing the individual consumption of at least part of the devices supplied by said secondary network.

13. The system according to claim 12, wherein said sleeve comprises means for the remote transmission of signals delivered by the electromechanical sensor.

14. The system according to claim 12, wherein said sleeve further comprises an electronic circuit for pre-processing signals delivered by the electromechanical sensor.

15. The system according to claim 12, wherein said processor is associated with a memory for saving a library of signatures of consumption of at least part of the individual devices.

16. The system according to claim 12, wherein said processor is programmed to perform a process of estimation and classification based on signals supplied by said electromechanical sensor.

17. The system according to claim 12, wherein said electromechanical sensor comprises at least one MEMS acceleration sensor, a piezoelectric sensor, an electret microphone and a MEMS microphone.

18. The system according to claim 12, further comprising at least one valve controlling the supply of at least one of said devices based on said information characterizing the individual consumption of at least part of the devices.

22. A computer program stored in a non-transitory storage media for implementing a system according claim 12, for controlling a processor for analyzing signals delivered by an electromechanical sensor with a view to extracting information characterizing the individual consumption of the devices supplied by a secondary network.

19. The sleeve for acquiring signals with a view to estimating the individual water consumption of a plurality of devices, comprising two tubular half-shells linked by a joint enabling the opening thereof so that it can be inserted around a pipe, and the closing thereof so that a sensor can be applied against a wall of said pipe.

20. The sleeve according to claim 19, further comprising means for adjusting the load pressure of the sensor on an outside wall of the supply pipe.

21. The sleeve according to claim 19, further comprising a connector for receiving a peripheral device containing an electronic memory wherein a computer file for updating the computer program controlling the processor for analyzing signals is saved.
