SYSTEM FOR DETECTING BALLAST EFFLUENTS Russian patent published in 2021 - IPC E03F1/00 G06F17/00 

FIELD: water drainage systems.

SUBSTANCE: invention relates to water disposal systems. System comprises a plurality of drainage networks, divided into m zones, m≥1, which include waste water consumption accounting units installed at outputs from each zone, equipped with information output means, at least one sensor of the amount of atmospheric precipitation with the possibility of determining rainfall intensities, a unit for determining water consumption in zones, a unit for determining water disposal in zones, to the input of which there are outputs of output means of outputting information of units for recording consumption of waste water, unit for estimating volume of atmospheric precipitation in zones, to the input of which outputs of at least one sensor of the amount of atmospheric precipitation are connected, a unit for assessing water disposal in zones from individual sources of water supply, unit for formation of zonal data bases containing data fields of time intervals k, water consumption water disposal water disposal from individual sources of water supply volume of atmospheric precipitation to the input of which are connected outputs of unit for determination of water consumption in zones, unit for determination of water disposal in zones, unit for estimating volume of atmospheric precipitation in zones, unit for estimating water discharge in zones from individual sources of water supply, unit for primary sampling of data from zonal databases on condition of equality of zero volume of atmospheric precipitation per day, to input of which is connected output of unit for formation of zonal databases. Unit for formation of zonal data bases is configured to generate data fields of time intervals k with duration Δt, n is number of intervals per day, i = 1, 2, …, n. Unit of primary sampling of data from zonal databases on condition of equality of zero volume of atmospheric precipitation for a day is made with possibility of sampling by condition of equality of zero volume of atmospheric precipitation for previous and current day. System is additionally equipped with subscriber water consumption database , output of which is connected to input of water consumption determination unit in zones, unit for formation of minimum actual values of volumes of water disposal in zones for each time interval Δt during dry days, h = 1, 2, …, m, k = 1, 2, …, n, - actual values of water discharge volumes at outlets of zones h in time intervals k duration Δt, to the input of which the output of the primary data sampling unit is connected, a hydraulic simulation unit configured to generate design values of water disposal volumes in the zones for each design time interval Δt during dry days, unit for determining the degree of deviation of water disposal volumes in zones configured to generate deviation coefficients, which are determined by dividing the minimum actual values of volumes of water disposal in zones by design values of water disposal volumes in zones at each interval of duration Δt, to the input of which the output of the unit of formation of minimum actual values of volumes of water disposal is connected and the output of the hydraulic simulation unit, a unit for detecting ballast inflows of waste water in zones made with possibility of preliminary detection of prospective subscribers in the zone, where the deviation coefficients will be greatest compared to other zones, to the input of which the output of the unit for determining the degree of deviation of water disposal volumes in the zones is connected.

EFFECT: wider field of use and high reliability of the system.
