In order to supply the raw water obtained from the river, reservoir or the water source to the drinking water or living water used in the household, the water treatment must be performed on the raw water obtained. In this way, the water purification plant for the treatment of raw water is composed of the water intake plant, the water purification plant, the mixed soil, the coagulant, the sedimentation, the filter paper, the purified water, and the reservoir.

First, when water is drawn into a water intake pipe through a large pipe in a river, a reservoir or a water supply source, the drawn water is moved to the station and stabilized, and then transferred to the mixed paper.

At this time, the coagulant, the alkaline agent and the coagulation assistant are added in addition to the water moved from the water tank, and the water and the medicine are mixed by using a mixer or a water drift, so that small particles in the water, It clumps into a mass and precipitates, removing the suspended matter floating on the water.

Then, after the water flows into the settling basin, foreign matter in the water sinks to the bottom, and the clean water in the upper part moves to the filter paper.

Subsequently, in order to remove fine particles in the water that have not been removed from the previous settling paper, the filter paper is cleanly filtered through the sand bed, thereby removing small particles that are invisible but remain in the water.

Finally, the water flowing into the purified water through the filter paper is apparently clean, but a disinfectant such as chlorine is injected in order to sterilize microorganisms such as germs present in the inside, and after the water is transferred to the reservoir, It is supplied to each household through a pipe.

Hereinafter, a water supply pipe network showing the arrangement of a plurality of water pipes formed in a blocked state with reference to FIG. 1 will be described in more detail.

For example, the largest amount of water is supplied between 6:00 am and 9:00 am, and the smallest amount of water is supplied the slowest through the water line between 1:00 am and 5:00 am The pressure pattern is known. Also, of all days of the week, water is supplied at the highest, highest pressure on Monday, followed by a large amount of water at high pressure on Sunday, and the lowest, and slowest, water supply on Tuesday. In addition, the greatest amount of water is supplied quickly through the water pipe during July and August, but in January the smallest amount of water is supplied the slowest way through the water pipe.

The prediction module 154 applies the flow pattern and the pressure pattern according to the time, day, and month to the artificial neural network, thereby estimating the demand amount of water for each hour, day, and month for a plurality of waterworks blocks blocked through machine learning do. At this time, it is possible to perform the machine learning by setting the time, day, and month of each flow pattern and the pressure pattern according to the hour, day, and month as input variables of the artificial neural network.

The power control module 156 generates a control signal for controlling the amount of power supplied to the water pipe control device for controlling the flow rate and water pressure of the water flowing through the plurality of water pipes according to a result of predicting the demanded amount of water, And transmits the control signal to the power supply unit 170. The power control module 156 compares the predicted water demand with a predetermined reference demand, and if the predicted water demand is less than the reference demand, the power supplied to the water control unit is reduced or blocked Or if the predicted water demand is equal to or greater than the reference demand amount, a second control signal for controlling power to be supplied to the water supply pipe control apparatus may be generated. At this time, the reference demand amount may be an average value of each block for a plurality of installed water supply pipes blocked by groups.

As a result, when receiving the DR message from the management server of the power management company, the water supply network management control system based on the IoT according to the present invention predicts the water demand amount required by each household, efficiently supplies the demanded demand to each household, The power consumption can be controlled.

The water pipe network power management control system based on the IoT of the present invention may further include a transmission unit 180 and a database 190 (not shown) in addition to the power supply unit 170, the data input unit 110, the DR message reception unit 130, ).

The transmission unit 180 analyzes the flow rate variation amount and the water pressure variation amount of water flowing in the plurality of water supply pipes based on the flow rate data and the pressure data, the flow rate data and the pressure data, and transmits the information to the remote measurement terminal send. When the user terminal is connected to the area where the plurality of water pipes are installed, the transmission unit 180 may transmit to the user terminal the amount of water demand predicted by time of day and predicted by day of the week.

The database 190 stores flow data and pressure data input to the data input unit, location information of the area where the plurality of water pipes are installed, block information indicating a state in which the plurality of water pipes are divided into groups, The date and time information of receiving the data, and the flow pattern and pressure pattern and the reference demand amount according to the time period, day of the week, and month generated from the control unit.

Hereinafter, with reference to FIG. 3, a method for controlling power management of a water supply pipe network based on IoT according to another embodiment of the present invention will be described in detail.

FIG. 3 is a flowchart of a power management control method of a water supply network based on IoT according to another embodiment of the present invention.

As shown in FIG. 3, the water supply network power control method based on the IoT of the present invention includes: a first step of supplying power to the plurality of water supply pipes blocked by the power supply unit 170, A predetermined amount of electric power is supplied to the water pipe control device for controlling the flow rate and water pressure (S210).
