Abstract:
A system configured to predict an inflow volume of rainwater, comprising:a rainfall volume measuring unit for measuring a rainfall volume that has fallen by a present time; a rainfall volume predicting unit for predicting a rainfall volume in a future time period; an inflow-volume measuring unit for measuring an inflow volume of rainwater that has flowed into an objective facility by the present time; a model identification unit comprising a nonlinear model that includes a Neural-Network model for calculating an inflow volume of rainwater from a rainfall volume, and a parameter determining part for determining degree and coefficient parameters of the nonlinear model, based on the rainfall volume that has fallen by the present time measured by the rainfall volume measuring unit and the inflow volume of rainwater that has flowed into the objective facility by the present time measured by the inflow-volume measuring unit; an inflow-volume predicting unit for predicting an inflow volume of rainwater that will flow into the objective facility in a future time period, based on the future rainfall volume predicted by the rainfall volume predicting unit, according to the nonlinear model and parameters determined by the model identification unit; and wherein (1) the rainfall volume predicting unit is associated with the inflow-volume predicting unit and the rainfall volume measuring unit, and (2) the parameter determining part is associated with the rainfall volume measuring unit, the inflow-volume measuring unit, and the inflow-volume predicting unit.
