BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water management system for reducing water leakage rate and increasing water flow rate,

The present invention relates to a water quality management system for reducing water leakage rate and increasing water flow rate.

Although waterworks projects are being invested heavily in expansion projects to meet water supply, replacement of old buildings, rehabilitation, and replacement of meters, water leakage rate is rising and oil production rate is stagnating due to aging and poor maintenance of waterworks.

Also, it is difficult to confirm the leakage phenomenon occurring in the water pipe embedded in the underground in the water pipe network which is generally used, and the leakage phenomenon occurring in the water pipe is affected by the water pressure in the water pipe. That is, when the water pressure in the water pipe is high, the amount of water leakage in the water pipe increases.

Especially, in the present water supply pipe in the water supply pipe network, unlimited supply of constants is possible without change in time zone. Therefore, in the middle of the night when the constant use is low, the water level of the water stored in the reservoir rises and the flow rate of the constant water in the water supply pipe decreases, There is a problem that the water pressure of the water tank is excessively increased to increase the water leakage rate.

In addition, since the water pressure in the water supply pipe fluctuates greatly repeatedly every day, there is a problem that the service life of the water supply pipe such as the water pipe is shortened and damaged.

As a countermeasure to prevent the increase of the water leakage in the water pipe, a water control valve or a pressure reducing valve for water pressure control is installed at a necessary position to adjust the water pressure of the water pipe and the minimum flow rate so that the water pressure in the water pipe is maintained at a proper water pressure , It is necessary to adjust the water volume so as not to excessively increase the water pressure in the water pipe in the night time zone.

However, in the past, it has been determined by the manager's experience to install the water-regulating valve or the pressure-regulating pressure-reducing valve and to adjust the water pressure so that the water pressure does not rise excessively during the night time, The water pressure is maintained and the surplus water supply is performed, thereby increasing the leakage.

Therefore, it is required to study the supply pressure and the determination of the supply quantity of the constant water by the time zone which can decrease the water leakage rate of the water supply pipe and increase the water flow rate.

Hereinafter, the water management system for reducing the water leakage rate and the water flow rate according to the present invention will be described in detail.

1 and 5, the RFID tag T is installed in the water pipes P located in the water supply block and the RFID tag T includes the type of the water pipe P and the history information Attribute information and position information for allowing the user to easily grasp the position of the water pipe P is stored. This is for the purpose of easily grasping the property information and the location information of the water pipe (P) in maintenance of the water pipe (P) buried in the ground or installing a new water pipe (P).

The data measuring unit 100 according to the present embodiment includes a water pressure measuring sensor (not shown) installed in a water pipe P located at least one critical point C selected in each water tap block in a blocked water supply pipe network do.

The hydraulic pressure measuring sensor successively measures the hydraulic pressure of the constant supplied to the water pipe (P) located at the critical point (C) and transmits data on the water pressure of the measured constant to the constant management server (200) in real time. The correlation between the hydraulic pressure of the constant supplied to the water pipes in the water supply block and the quantity of the constant supplied to the water supply pipe in the water supply block can be obtained through the property information of the water supply pipe (P) and the water pressure information measured by the pressure measurement sensor .

In the present embodiment, the critical point (C) is selected by the analysis of the water supply pipe network, and the degree of water pressure decrease in the water supply block according to the water quantity change supplied to the water supply pipe in the water supply block by the water supply pipe network analysis It is the point that receives the least or the least effect such as hydraulic pressure change time. In this embodiment, the critical point C can be selected as the point at which the water pressure of the constant is lowest and the point at which the water pressure is highest (for example, the branch point of the water supply pipe or the end point of the water supply pipe) A number of points may be selected depending on the type and scale of the waterworks block.

The analysis of the water supply pipe network uses hydraulic analysis using Hazen-Williams formula, Darcy-Weisbach and Manning formula, and the water supply pipe network analysis is performed at the control point (A) of the reservoir and the water control valve (V2) And the time during which the hydraulic pressure falls from the operation to the critical point (C) are calculated to control the water pressure and the water quantity in the water supply block. In addition, the analysis of the water supply pipe network can also determine the control time of the water control valve (V2) by calculating the time during which the water pressure falls at the critical point (C) from the water control valve control point (A) at the reservoir control point.

The critical point C is a point at which a usage pattern of a constant water time constant of the water supply block can be calculated based on the hydraulic pressure of the constant supplied to the water supply pipe P in the water supply block. At the point (C), the water leakage amount of the constant can be reduced as much as possible by controlling the quantity of the water supplied to the water supply block at the control point (A) according to the waterworks facility standard so as to maintain the minimum water pressure which does not interfere with the use of the constant.

The water pressure measurement of the constant by the data measurement unit 100 can be controlled by the constant management server 200 which will be described later and the data concerning the water pressure of the constant measured by the data measurement unit 100 can be transmitted through a wired or wireless communication And transmitted to the constant management server 200 in real time.

In addition, data on the water pressure of the constant measured by the data measuring unit 100 may be transmitted to the terminal 300 in real time via wired or wireless communication.

The constant management server 200 according to the present embodiment calculates a usage pattern of a constant time zone of the water supply block based on the water pressure of the constant at the critical point C transmitted from the data measurement unit 100, And controls the water pressure and water quantity of the water supplied to the water pipes (P) located in the water supply block according to the usage patterns of the constants per time zone.

2, the constant management server 200 includes a first communication module 210, a first memory module 220, a usage pattern calculation module 230, a valve control module 240, An update determination module 250, and a leakage determination module 260.

The first communication module 210 receives water pressure information of a constant measured at the water pipe P located at the critical point C transmitted from the data measurement unit 100 via the wired or wireless communication with the data measurement unit 100 . The constant management server 200 also transmits a control signal for causing the data measurement unit 100 to measure the water pressure of the constant flowing in the water pipe P located at the critical point C through the first communication module 210 do.

The first memory module 220 stores programs and data necessary for driving the constant management server 200.

The first memory module 220 stores the water pressure information of the constant measured at the water pipe P located at the critical point C received from the data measurement unit 100 via the first communication module 210. The water pressure information of the constant measured in real time in the data measuring unit 100 is stored and updated in the first memory module 220 through the first communication module 210. [

The usage pattern calculation module 230 calculates the usage pattern based on the water pressure information of the constant measured in the water pipe P located at the critical point C transmitted from the data measurement unit 100 and stored in the first memory module 220 And calculates a usage pattern of constants for each time zone of the waterworks block.

For example, the usage patterns of constants for each time zone of the waterworks block can be obtained by averaging the water pressure information of constants measured in the water pipe P located at the critical point C for a predetermined period of time.

The usage pattern calculation module 230 according to the present embodiment statistically analyzes the water pressure change of the water supply block, for example, as shown in FIG. 3, and calculates the distribution of the water pressure supplied to the water supply block.

3 is a graph showing a change in the water pressure measured at the water pipe P located at the critical point C per day and is a value obtained by averaging the change in the water pressure for each predetermined period of time (for example, seven days) It can be defined as a usage pattern of a star constant.

Also, as shown in FIG. 3, it can be seen that the water pressure of the water supply block is generally lower than the water pressure of the other sections during the night time (AM 1:00 to AM 6:00).

In this way, since the usage patterns of the constants for the waterworks block in the time zones are lowered at the midnight hour, the water pressure of the water supplied to the water pipes (P) located in the waterworks block in the nighttime, Can be prevented.

5, the valve control module 240 sets a constant to the water pipes P located in the water supply block according to the usage patterns of the constants for each time zone of the water supply block calculated by the usage pattern calculation module 230 And controls the quantity control valve V2 installed at the control point A of the supplying reservoir. That is, as shown in FIG. 3, the valve control module 240 controls the flow rate of the water control valve 240 so that excessive water pressure is not applied to the water pipes P located in the water supply block at the midnight hour, (V2).

In the prior art, the water quantity control valve V2 is adjusted so as to supply the water quantity set by the manager arbitrarily so that the water pressure of the constant water supplied to the water supply pipe P in the water supply block is supplied unlimitedly without changing from time to time. There is a problem that the water leakage increases in the water pipes (P) due to excessive water pressure rise in the middle of the nighttime. Therefore, in this embodiment, the quantity of the water supplied through the water control valve V2 at the control point A is adjusted in accordance with the usage pattern of the constants for each time zone of the water supply block, By regulating the water pressure of the supplied water, it is possible to remarkably reduce the water leakage amount generated in the water supply pipes (P).

As another example, the usage patterns of the constants for each time zone of the waterworks block can be obtained by combining the factors such as the weather and the temperature in units of month, day of the week, hour, minute, and the usage pattern of the constant at a specific time of a specific day of a specific month.

Specifically, the quantity of the constant is determined by reflecting the usage amount of the previous year's constant and the usage amount of the monthly constant of the newly established consumer during the period. It is possible to determine a very reasonable number of constants by determining the number of constants in consideration of the factor of each day, temperature, and climate, and it is possible to maintain the optimum water pressure in real time in connection with the water pressure at the critical point (C) to be.

Equation (1): Q = q1 x (? +? + -?)

Here, Q is the quantity (m 3 / h) of the supplied constant (m 3 / h), q 1 is the amount (m 3 / h) of the same time period constant for the same date of the previous year, and α is the weight value for the day And β is a weighted value for temperature (correction of temperature deviation for the same date, analysis of a constant increase / decrease pattern of a constant due to one year temperature change in a water supply block, , Δ is the weighted value for climate change (automatically calculating the exponent value taking into account changes in the number of consecutive days and constants, such as a clear day or rainfall day), and ε is a large-scale consumer in the waterworks block or a large water meter The number of installers and the weighted value according to the type of industry (using tap water usage pattern analysis data at a specific time).

The water pressure at the critical point C is correlated in real time with the quantity of the constant supplied from the control point A obtained using the equation (1), and the critical point C ) Can be maintained, so that leakage can be drastically reduced.

On the other hand, the usage amount of the constant may vary from day to day, season, temperature, weather, and so on. In response to this, the constant management server 200 updates the usage pattern of the constant of the user block in accordance with the usage amount of the constant .

Specifically, the water pressure and water quantity information of the constant in the water pipe (P) located at the critical point (C) by day, season, temperature, weather, etc. can be changed from time to time depending on the usage amount of the user.

Accordingly, the usage pattern update determination module 250 according to the present embodiment calculates the usage pattern update determination module 250 based on the usage pattern of the constants for each time zone of the waterworks block calculated by the usage pattern calculation module 230, in the water pipe P located at the critical point C The water pressure information of the constant and the pressure information of the constant measured in the water pipe P located at the critical point C transmitted in real time in the data measurement unit 100 are compared with each other, It is determined whether or not it is updated.

[

The water management method according to the water management system for reducing the water leakage rate and increasing the water flow rate according to the present invention will now be described.

7 is a flowchart showing a water management method according to the present invention.

Referring to FIG. 7, first, at least one critical point C in the water supply block is set or selected through the water supply pipe network analysis (S100).

The water pressure measuring sensor constituting the data measuring unit 100 is installed in the water pipe P located at the critical point C so that the water pressure of the constant water supplied to the water pipe P located at the critical point C is continuously (S200).

The constant management server 200 stores the water pressure information of the constant at the critical point C transmitted from the data measurement unit 100 in the first memory module 220 and the usage pattern calculation module 230 A usage pattern of constants for each time zone of the water supply block is calculated based on the water pressure information of the constant at the critical point (C) stored in the one memory module (S300).

The valve control module 240 of the constant management server 200 controls the water supply valve V1 installed in the water supply pipe located at the critical point to adjust the water pressure of the constant water supply pipes P provided in the water supply block And controls the water quantity control valve V2 installed at the control point A of the reservoir to control the quantity of the water to be supplied to the water pipes P located in the water supply block at step S400.

On the other hand, according to the property information of the water supply pipes (P) in the water supply block and the usage pattern of the constants for each time zone of the water supply block, the water pressure and quantity information of the constant supplied to the water supply pipes (P) The constant management information including the water pressure information of the constant measured at the water pipe P located at the point C is displayed on the terminal 300 together with the electronic map displaying the water tap block.

And, among the plurality of pieces of information constituting the constant management information, the changed information is updated and displayed on the terminal 300 (S500).

The water pressure information of the constant supplied to the water pipe P located at the critical point C and the water pressure information of the constant water pressure P located at the critical point C transmitted in real time in the data measurement unit 100 When the water pressure information of the constant measured by the water pipe P deviates from a predetermined range, the usage pattern update determination module 250 of the constant management server 200 updates the usage pattern of the constant water block by time zone It is determined that it is necessary (S600).

When the usage pattern update determination module 250 determines that the update of the consumption pattern of the constants block in the water supply block is necessary, the usage pattern calculation module 230 updates the stored usage pattern in the first memory module 220 And calculates the usage pattern of the constants for each time zone of the water supply block based on the water pressure information of the constant measured at the water pipe (P) located at the critical point (C).

The water pressure information of the constant supplied to the water supply pipe P located at the critical point C and the critical point C transmitted in real time in the data measurement unit 100 according to the usage pattern of the constant time- The water leakage determination module 260 determines whether or not the water pressure information of the constant water pipe information is constantly increased by comparing the water pressure information of the constant measured in the water pipe P located in the water supply pipe P, It is determined that leakage occurs (S700). Further, it is possible to detect the occurrence of leakage of the water pipe (P) by the water leakage sensor (S).

When it is determined that water leakage occurs in the water supply pipe P by at least one of the water leakage determination module 260 and the water leakage sensor S, the valve control module 240 of the water management server 200 Cuts off the water supply valve V1 supplying the water to the water pipe P where the water leakage occurs (S710).

In this embodiment, however, even when the constant supply valve V1 is shut off, since the minimum movable range of the constant supply valve V1 is set to 5% or more, a minimum number of constants can be supplied to the user side along the water pipe P Therefore, the inconvenience of the user can be solved to some extent.

However, when it is determined that water is leaked from the water pipe (P) through which the constant flows, or when a leak is detected, a malfunction of the water supply valve (V1) and a replacement operation of the water pipe (P) (B) is installed in the water pipe (P) in the present embodiment, and the bypass tube (B) is separately provided in the bypass pipe (B) in order to sufficiently supply the constant to the user in case of an emergency, The emergency operation valve 400 is automatically operated when an operating water pressure equal to or higher than a set pressure set by the user is applied. A sufficient amount of constant can be supplied to the user without interrupting the supply of the constant by the emergency operation valve 400 as described above.

In addition, the constant management server 200 displays the location of the water pipe P determined to have leaked water on the electronic map displayed on the terminal 300 (S720).

When the user wants to know the route to reach the water pipe P where the water leakage occurs, the user can know the property information of the water pipe P where the leaked water displayed on the display module 330 of the terminal 300, The leakage water pipe detection unit 345 detects the leakage water pipe P stored in the second memory module 320 of the terminal 300 based on the at least one water pipe P property information and the location information selected by the user The display module 330 searches for the water pipe P and displays a moving direction and a moving distance for reaching the corresponding water pipe P retrieved from the current position of the user.

As described above, according to the water management method for decreasing the water leakage rate and increasing the water flow rate according to the present invention, the water pressure of the constant water supplied to the water supply pipes (P) located in the water supply block according to the usage patterns of the constants, (P) can be maintained by maintaining the minimum water pressure at which the user is not inconvenient so that the water pressure does not excessively rise in the water pipe (P) during the night time when the use of the water is low, And thus the flow rate can be increased. In addition, since the leakage amount is reduced, the production amount of the constant water can be reduced, thereby reducing the cost of producing the water.

Figure 112017021562255-pat00001

[Table 1] shows the effect of reducing the production of constant water when the water pressure of the water supplied to the water supply pipes (P) located in the water supply block is adjusted according to the usage patterns of the constants by time of the unit water supply block.

Is Table 1. Referring to, for example, if it is not controlling the pressure in deoknam when the average daily production is constant and 205,022m 3, adjust the daily average water pressure constant production 173,470m 3. The average daily production decreased due to the constant pressure regulation corresponds to 31,552m 3, when converted based on them on an annual basis can be a constant production cost of about 2,453 million.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Accordingly, such modifications or variations are intended to fall within the scope of the appended claims.
