Zusammenfassung: | The invention discloses a method for detecting a pressure disturbance event of a water supply network. In order to solve the problem of high false alarm rate of a conventional statistical method for abnormal events of a water supply network, a time-frequency domain conjoint analysis method is adopted, and a pressure sudden change signal is identified by combining a frequency domain wavelet singular point detection method on the basis of time domain conventional detection; pressure disturbance event detection including normal water inlet valve opening and closing, pump set starting and stopping switching and abnormal pipe explosion is achieved. According to the method, the amplitude sensitivity characteristic of the time domain statistical method and the frequency conversion sensitivity characteristic of the frequency domain wavelet singular point detection method are fully utilized, and convenience is provided for further detection of pipe burst of the water supply pipe network.
