Improved detection and characterization of anomalies in a continuum of water

A method for detecting and characterizing anomalies in a water continuum, comprising:

• the reception of measurements of a plurality of physical quantities arising from a plurality of sensors of the plurality of physical quantities in the water continuum;
• the generation of a plurality of time windows of measurements;
• for each window of said plurality:
• the obtaining of a set of values transformed by at least one transformation of the measurements over the time window;
• the detection of a normal or abnormal state of the time window, said detection being parameterized on the basis of sets of transformed values arising from the application of the at least one transformation to time windows of previous measurements of the at least one sensor;
• the detection of an anomaly in the water continuum, as a function of a number of time windows exhibiting an abnormal state;
• the execution of a set of predefined detection rules for detecting a variation of one at least of the physical quantities;
• if an anomaly in the water continuum is detected, the assignment to the anomaly of an anomaly type associated with a variation of a subset of the physical quantities, if the variation of one at least of the quantities of the subset is detected.

A computer program product comprising program code instructions recorded on a medium readable by a computer comprising a processor for the detection of anomalies in a water continuum, said computer program comprising programming means readable by computer for:

• receiving measurements of a plurality of physical quantities arising from a plurality of sensors of the plurality of physical quantities in the water continuum;
• generating a plurality of time windows of measurements;
• for each window of said plurality:
• obtaining a set of values transformed by at least one transformation of the measurements over the time window;
• applying a detector of anomalies to the set of transformed values so as to detect a normal or abnormal state of the time window, said detector of anomalies being parameterized on the basis of sets of transformed values arising from the application of the at least one transformation to time windows of previous measurements of the at least one sensor;
• detecting an anomaly in the water continuum, as a function of a number of time windows exhibiting an abnormal state;
• executing a set of predefined detection rules for detecting a variation of one at least of the physical quantities;
• if an anomaly in the water continuum is detected, assigning to the anomaly an anomaly type associated with a variation of a subset of the physical quantities, if the variation of one at least of the quantities of the subset is detected.
