摘要
A water network monitor, monitoring system and method comprising: at least one sensor operable to sense one or more parameters of a water network; and an analyser to analyse data points recorded over time from the water network by the at least one sensor, the analyser having an input comprising the data points recorded over time from the water network and an output comprising an event probability P(event) that an event has occurred which affects the water network from which the data points were recorded, the analyser comprising: an outlier detector to determine a measure of abnormality (D) from an outlier detection algorithm for each of the data points; and an outlier decay discriminator (ODD) to calculate an outlier probability (Po) for each of the data points based on each data points measure of abnormality (D), wherein the outlier probability is decayed over time, the output of the ODD comprising an event probability P(event), wherein P(event) is based on the decayed outlier probability.
