Embodiment Construction
[0104] Such as figure 1 As shown, the water leakage detector 104 of an embodiment of the present invention collects and compares noises at two different points of the water supply pipeline (or unit water supply pipeline), including: a collection device 20 and a processing device 40 . Acquisition device 20: collecting sound signals for preprocessing. Processing device 40: perform Fourier function transformation on the sound signal, perform frequency analysis and calculation, extract the characteristics of the sound signal, estimate the power spectrum of the sound signal, and estimate and analyze the main frequency components of the signal according to the power spectrum diagram. Peak and bandwidth to determine whether there is leakage. Such as Figure 3a It is the record result of water leakage at the detection point, the peak value (Level) is very high, and the bandwidth (Spread) is small. Figure 3b Among them, the peak (Level) is very small, and the bandwidth (Spread) is ...
