Description

The invention relates to water supply and sanitation systems, and in particular to systems for assessing the balance of water supply and drainage, as well as leak detection of pressureless pipelines of drainage systems.

It is known “Device for automated detection of pipeline ruptures in the sewage system” (see utility model patent No. 86274, Russian Federation: IPC F17D 5/02 / Khramenkov SV, Bogomolov MV, Pak VN, Zarudin V.M .; published on August 27, 2009), containing a software logic controller, an automated workstation at a local dispatch center at a sewage pump station, an automated workstation at a central dispatch center of a sewer system, pressure and flow sensors in pipelines that cut off valves with electric actuators of pipelines, while the flow rate of wastewater is controlled by two or more simultaneously operating pressure pipelines of a sewage pump station, and pressure control in pressure pipelines is carried out with open sectional valves between pressure pipelines, and flow and pressure sensors are installed in chambers at the beginning of pressure pipelines.

The disadvantage of this technical solution is the limited scope that does not allow it to be used to detect leaks in pressureless pipelines of drainage systems, since it is designed to detect ruptures of pressure pipelines of sewage pumping stations.

The closest analogue to the claimed invention is the utility model "Control system for a complex of water supply and wastewater disposal" (see utility model patent No. 80468, Russian Federation: IPC EV03 / 02 (2006.01), G06F 17/00 (2006.01) / Karmazinov F.V., Bezdenezhnykh A.G .; publ. 02.10.2009, Bull. No. 4), which includes many networks and water supply and sanitation facilities controlled via communication channels, containing means for input and input / output of information and means to execute many programs. At the same time, the network and water supply facilities included nodes for regulating the supply and metering of water consumption by subscribers, and the network and water disposal facilities included nodes for metering wastewater consumption by the subscriber.

There is a development option when the subsystem for regulating the supply and metering of water flow at the subscribers includes an input / output means and pressure sensors for supplying, supplying and consuming water, position valves of control valves associated with the means for executing commands, a water consumption sensor, a regulation sensor hydraulic modes of the water supply network, an automatic sampler, the input of which is connected to the output of the water quality sensor.

There is a development option when the means of inputting information connected to the sensors of the level of the wet compartments of the National Assembly, power consumption, the level of filling of the collectors and the amount of precipitation are included in the nodes of the metering of wastewater consumption among subscribers;

The specified system is characterized by a narrow scope, because:

- it can be used to manage water supply and sanitation systems in only small cities, because by structure it is a centralized management system that does not take into account differences in the operating modes of individual zones of these systems;

- it does not allow to diagnose the volume of inflows into the groundwater drainage systems.

The objective of the present invention is to expand the scope of the known system.

The problem is solved in such a way that in the well-known system containing many water supply networks, which include water metering stations for subscribers with information output means, and drainage networks, which include waste water metering stations and precipitation sensors, in accordance with the present invention:

- rainfall sensors are configured to determine rain intensities;

- water supply and sanitation networks are divided into zones so that the zones of water supply networks coincide with the zones of water disposal networks;

- metering stations for wastewater discharge are installed at the outlet of each sewage zone and are additionally equipped with information output means.

In addition, the system is additionally equipped with:

- a unit for determining the outdoor temperature;

- a unit for determining the actual performance of at least one local surface drain system of a metropolis;

- a unit for determining water consumption in zones, to the input of which the outputs of the means for outputting information from metering stations of water for subscribers are connected;

- a unit for determining water disposal in zones, to the input of which the outputs of the means for outputting information from metering stations for wastewater consumption are connected;

- a unit for assessing the amount of precipitation in the zones, to the input of which the outputs of the sensors for precipitation are connected;

- a unit for assessing water disposal in areas from individual sources of water supply;

- at least one water level sensor in the pond of a metropolis,

The combined use of the indicated distinctive features in the inventive system allows to obtain a positive effect, namely, that the scope of the system is expanding, because:

- it can be used to manage water supply and sanitation systems of large cities (megacities), since it provides for distribution management by zones, taking into account differences in their operating modes. This is achieved due to the presence of distinctive features No. 2, 3, 7-10, 12-17;

- it allows you to diagnose the volume of inflows into the groundwater drainage system. This is achieved due to the presence of distinctive features No. 1, 4-6, 11, 15, 16-17.

The system proposed by the authors is structurally different from the prototype.

Moreover, each subscriber 4 of each zone records the consumed water by the water metering units 2.

неучтенных вод от неизвестных источников (см. позиция 5). В отличие от объемов, поступающих из дренажных отверстий, объем $$V_k^{неучт}$$

является функцией времени и, как показано на фиг. 4, не зависит от уровня H_k воды в водоеме 16 мегаполиса.In particular, in FIG. 2, in order to prepare the initial data, the calculation results (using hydraulic calculation methods) of the volumes of drainage water entering the drainage network 5 from the reservoir of 16 megalopolis through three drainage holes located at different heights are presented. The dependences of the volumes of water inflow on the levels H _{k of} water in the pond for different openings are shown by positions 1, 2, and 3. Position 4 shows the sum of these volumes. In addition to this, in FIG. Figure 3 presents the result of determining the indicated volumes under conditions when metering units during measurement allow an error of 0 to 20%, distributed according to a uniform law. In addition, in FIG. 4 shows an option when volume is additionally supplied to the collector of drainage networks 5 $$V_k^{ne\mathrm{at}ht}$$

unaccounted waters from unknown sources (see position 5). Unlike volumes coming from drainage holes, volume $$V_k^{ne\mathrm{at}ht}$$

is a function of time and, as shown in FIG. 4, does not depend on the level H _{k of} water in the reservoir 16 megalopolis.

, т.к. после трех фильтрационных выборок значения $$V_k^{водопотребл.}-V_k^{водоотвед.}-V_k^{водоотвед.и.и.}$$

стремятся к нулю.As a result, in FIG. 4, position 4 shows the change in volume $$V_k=V_k^{dRen}+V_k^{ne\mathrm{at}ht}$$

because after three filtering samples values $$V_k^{\mathrm{at}\mathrm{about}d\mathrm{about}P\mathrm{about}tRebl.}-V_k^{\mathrm{at}\mathrm{about}d\mathrm{about}\mathrm{about}t\mathrm{at}ed.}-V_k^{\mathrm{at}\mathrm{about}d\mathrm{about}\mathrm{about}t\mathrm{at}ed.\mathrm{and}.\mathrm{and}.}$$

tend to zero.

In FIG. 5, position 1 in a graphical form presents the result of the first stage, implemented in block 21 of the balance sheet, in the form of points with coordinates H _k and V _k . Additionally, the position 2 indicates the result of the second stage in the form of a function V = f (H) of the inflow of water from reservoirs, which at the points H ₁ , ..., H _k , ..., H _n takes values as close as possible to the values of V ₁ , ... V _k , ..., V _n . For comparison, 3 denotes the theoretical function Vt = f (H) shown in FIG. 2 by position 4. A comparison of the functions V and VT and the result of their high convergence confirms the practical applicability of the proposed system.

дренажных вод.At the third stage, in block 21 of the balance assessment, as a result of the analysis of the function V = f (H) and its dependence on the water level H _k in the megalopolis, the fact of the presence of volumes in this zone is established $$V_k^{dRen}$$

drainage water.

Thus, the proposed system meets the criterion of "industrial applicability".
