Abstract

FIELD: data processing.

SUBSTANCE: automatic monitoring and control of water supply is carried out using microprocessor unit, level sensors in a drinking water reservoir (h), pressure in backbone network, water consumption by consumers (Q_u), water pressure at outlet of pump stations (P_h) and at managing point (P_dt), actuating mechanisms. At onset of day electricity tariff, subroutine depending on performance of pumps and water consumption by consumers calculates minimum value P_dt and h of water, compares said values with readings of sensors and at equal or less values transmits a command to actuating mechanisms to feed water into water storage tank. At onset of night zone electricity tariff, subroutine for controlling water reserves analyses water consumption and based on consumption of water by consumers at end of night zone transmits a signal to actuating mechanisms and then to pumps for complete filling of water storage tanks.

EFFECT: providing uninterrupted water supply and reduction of electric power costs.

Description

The invention relates to the field of water supply and can be used for automatic control and regulation in the water supply system of settlements. The invention allows to reduce the cost of electricity. The method of automatic control and management consists in regulating water supplies according to the daily schedule and optimizing the operating time of pumping equipment.

A known control system for pumping equipment of a water tower [1], comprising a controlled switched element, a pump, a device for continuously converting a measured parameter into an electric unified current output signal, an adjustable setpoint adjuster, two comparison elements and a real-time clock.

A disadvantage of the known system is the increased energy consumption due to the lack of a subroutine for analyzing water supply during the day and night.

The closest analogue is a method of automatic control of a water supply system of a city or region [2], which includes placing a plurality of sensors at water supply facilities, transmitting information from them to the personal computer of the control room, on the storage medium of which the water supply system control program is recorded.

The disadvantage of this method is the increased energy consumption due to the management of the water supply without taking into account the night tariff for electricity.

The technical result of the invention is uninterrupted water supply and reduction of energy costs due to automatic control and management of the water supply in the water supply system, including at night, at the rate of the night zone.

The technical result is achieved in that the control method using a microprocessor unit, level sensors in the drinking water tank (h), pressure in the mains network, water consumption by consumers (Q _p ), water pressure at the outlet of pumping stations (P _n ) and at the dictating point (P _dt ), actuators, is provided by the following algorithm. Upon the arrival of the daily tariff, the subprogram, depending on the performance of the pumps and the water flow by consumers, calculates the minimum value of P _dt and h of water, compares them with the readings of the sensors and, at equal or lower values, sends a command to the actuators to supply water to the water reserve tank. When the zone of the night tariff for electricity sets in, the water supply management subprogram analyzes water consumption and, taking into account the water consumption by consumers, sends a signal to the actuators by the end of the night zone and then to the pumps to completely fill the water supply tanks.

The proposed method for automatic control and management of water supply of settlements was tested in LLC UHH "Shimyak" Ufa district of Belarus. Measurements were made using the portable electric power quality analyzer CIRCUTOR AR.5L (code M80111 registered in Rosreestr). The calculations reveal an annual savings of 300 thousand rubles (due to the operation of the automatic control and management system for water supply according to the schedules of the daily and night electricity tariffs, and the reduction in the number of dispatch services).
