Embodiment Construction
[0104] In order to make the technical means and creative features realized by the present invention easy to understand, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and examples.
[0105] The following combination figure 1 and figure 2 The present invention is further described.
[0106] In this example, a DMA area is considered, such as figure 2 . The DMA area includes two water inlets and four water outlets, of which the water inlet and outlet have flow measurements. Six flow data are collected through the SCADA system, and the water demand data is obtained in the DMA area after calculation. The sampling time of the obtained water demand is one hour, that is, there are 24 water demand data in one day, and the three-day water demand data and the four-day weather data (three-day weather data plus one-day weather forecast data) are used to predict the water demand for one day way to train ...
