Real-time water pressure calculation system in water distribution network

摘要

The water supply pipeline real-time virtual water pressure calculation system according to an embodiment of the present invention is a water level of a drainage basin, the water pressure at the target point for which the virtual water pressure is to be calculated, and the flow rate and water pressure of the measurement point that is a point between the drainage basin and the target point on the water supply pipe. measuring instruments, respectively; After the measurement of the measuring instrument is completed, data pairs are extracted from the water level of the reservoir - the flow rate of the measuring point, the water level of the reservoir - the water pressure at the measuring point, the flow rate of the measuring point - the water pressure at the measuring point. part; a relational expression deriving unit for deriving a relational expression for the water pressure at the target point by inputting at least one of the water level of the reservoir, the water pressure and the flow rate at the measurement point as a variable after the extraction of the data pair is completed; and a virtual water pressure calculation unit for calculating the virtual water pressure of the target point by inputting at least one of the water level of the reservoir, the water pressure and the flow rate of the measurement point into the relational expression after the relational expression is derived.
