RAINWATER DRAIN SUPPORT SYSTEM AND METHOD, ITS CONTROL SYSTEM AND METHOD

摘要

PPROBLEM TO BE SOLVED: To provide a rainwater drain support system and a method which can reduce the number of variables input to an inflow forecast model of an inflow forecast section of the system, can make such forecasting at the inflow forecast section easier, and can forecast the quality of inflow rainwater. PSOLUTION: The rainwater drain support system is provided with a rainfall measurement section 10 for measuring rainfalls at a plurality of places and a linear mapping section 41 for making the linear mapping of time data matrix for rainfalls measured. An inflow forecast section 42 forecasts the inflow of rainwater by means of the linear mapping data. The rainwater drain support system forecasts the quality of inflow water by a system identification method using a nonlinear Hemmerstein model. The rainwater drain control system is provided with a detecting means to detect water level at a prescribed point upstream the pump facilities where water flows in, and an alteration means to change at least one of the preset rainwater pump start and stop water levels in accordance with water running conditions.
