| description | The invention discloses a small leakage detection method based on an exponential weighted moving average algorithm, which comprises the following steps of: collecting flow data of a water consumptionstable period, estimating a reference water consumption range of the water consumption stable period through frequency statistics, and verifying the reasonability of the estimated reference water consumption range through setting confidence coefficient, eliminating interference of large low-value fluctuation of flow data according to the reference water consumption range, and finally detecting small leakage in the DMA pipe network through an EWMA algorithm. The flow change trend is analyzed through the EWMA algorithm, the discovery time of small leakage events is greatly shortened, a manager can make a quick response and guide leakage detection personnel to optimize the priority of leakage detection, targeted and important leakage detection is achieved, and the method has high applicationand economic value and is |
