SYSTEM OF WATER INFLOW ESTIMATION Russian patent published in 2017 - IPC E03B1/02 

FIELD: physics.

SUBSTANCE: system contains a number of water supply (1) and water discharge (6) networks, divided into zones so that the zones of water supply networks coincide with the zones of water discharge networks, which include water metering units (2) and information output means (3). The system additionally comprises of the units (7) for the wastewater flow recording with the information output means (8), precipitation sensors (9), a determination unit (10) of water consumption in the zones, a determination unit (11) of water discharge in the zones, an evaluation unit (12) of the precipitation amount in the zones, an evaluation unit (13) of water discharge in the zones from individual water supply sources, at least one water level transmitter (14) in the reservoir (15) of an inhabited locality, a forming unit (16) of zonal databases containing k date data fields, water consumption , water discharge , water discharge from individual water supply sources , water levels in the reservoir of an inhabited locality H_k, amount of precipitation to the input of which the outputs of the determination unit (10) of water consumption in the zones, the unit for determining the water disposal in the zones, the evaluation unit (12) of the precipitation amount in the zones, the evaluation unit (13) of water discharge in zones from individual water supply sources and at least one water level transmitter (14) in the reservoir (15) of an inhabited locality, a balance estimation unit (17) configured to generate a plurality of n pairs of V_k values and corresponding A_k arguments, and also the definition of the function V = f₁(A) water inflow, which at points A₁, …, A_k, …, A_n takes values as close as possible to the values of V₁, …, V_k, …, V_n or equal to these values. The water metering units are installed at the inlet of each water supply zone. The evaluation unit of the amount of precipitation in the zones is designed to evaluate the amount of precipitation H_{k prec} per day. The balance estimation unit is configured to generate a plurality of n pairs of V_k values and corresponding A_k arguments from zonal databases, with the possibility of determining V_k subject to dependency, with the possibility of forming A_k arguments as a function A_k= f₂= (H_{k prec}, H_k). The system is further provided with an input unit (18) of predicted values of H_{k prec pred} volume of precipitation in the zones, an input unit (19) of predicted values of H_{k pred} water levels in the reservoir of the inhabited locality, an input unit (20) of predicted values of water consumption in the zones, an input unit (21) of predicted values of water discharge from the individual water supply sources , a water discharge prediction unit (22), designed to estimate the predicted values of in the zones in the form of . The output of a forming unit (16) of zonal databases is connected to the input of the balance estimation unit (17). Outputs of the input unit (18) of predicted values of the H_{k prec pred} volume of precipitation in the zones, the input unit (19) of predicted values of the H_{k pred} water level in the reservoir of the inhabited locality, the input unit (20) of predicted values of water consumption in the zones, the input unit (21) of predicted values of water discharge from the individual water supply sources are connected to the input of the water discharge prediction unit (22).

EFFECT: improvement of accuracy of the assessment of the water supply and discharge balance and expansion of the application scope of the system.
