Description

Water intergrated leakage management apparatus

The present invention relates to a water supply integrated leakage management device.

The water supply system produces water from the water treatment plant and supplies it to the customer through the water supply pipeline. The distribution pipeline is divided into large blocks, medium blocks, and small blocks by zone.

On the other hand, between the block and the block, usually a distillation valve is installed and a pressure gauge and a flow meter are installed, and the purpose of installing the distillation valve is to block construction by separating a block from the block in case of construction work or leaking water. For the purpose of normal supply of constant water, the pressure gauge is to determine whether the pressure of the block is appropriate, the flow meter is to determine the total supply amount, etc. to the block.

In such a water supply block, there is generally a difference from the amount of flowing water that is metered in the supply amount and the customer price of the block. The difference arises for a number of reasons. Among them, the main factor is leakage due to pipe rupture and leakage caused by pipe joints, etc., and this is defined as leakage amount, and due to water supply in the pipeline, water use in the water treatment plant, water plant, etc. Quantity is called anhydrous amount. Therefore, the amount of leakage and anhydrous amount is important not only to accurately calculate the amount of flow, but also to identify the amount of leakage and the location of leakage.

Conventionally, such a leakage calculation method has an integrated flow rate approach and a minimum flow rate approach. The integrated flow approach considers the constant supply of water over a period of time and the meter reading measured as an effective quantity, and calculates the difference between the supply and the effective quantity as a leak. In addition, the minimum night flow measurement method is a method of estimating the measured measurement value for each block as a leakage amount on the premise that no constant is used in the customer at the midnight time. However, the above method is difficult to accurately estimate the actual amount of leakage, and since the calculation method itself is inferred and made by hand, there is no limit to the practical use.

The present invention has been made to solve the above problems, to provide a water supply integrated leakage management device that can detect the amount of water in the water supply facilities, determine the leakage based on the detected amount of water to effectively detect the leakage state. There is.

The present invention for achieving the above object, the detection unit is installed in the water supply pipe of the water supply pipe network of the water leakage determination target area to measure and transmit the flow rate value; A database storing the flow rate values of several months measured at the customer on the settlement date; And calculating the estimated total monthly flow rate of the previous month based on the leak determination time point for the leak determination target region with reference to the flow rate values measured in the customer stored in the database, and measured and transmitted by the sensing unit. And a control unit for determining whether or not a leak is obtained by comparing the estimated total customer flow rate and the supply flow rate after calculating the supply flow rate for the previous month based on the leakage determination time point of the leak determination target region using the flow rate value. In the case of a house that has moved, the moving date before moving is calculated using the average daily usage of the month, and the moving amount after moving is calculated based on the average usage flow rate for the month over several years. Calculate the amount of usage after moving day and add it up to calculate estimated total usage Characterized in that.

In addition, the control unit of the present invention calculates the amount before the settlement date using the average daily usage of the corresponding month, the amount of use after the settlement date is calculated after the settlement date with reference to the usage of several months It is characterized by calculating the total usage of the estimated customer by adding up.

In addition, the control unit of the present invention is characterized by identifying the measured flow rate by grasping the measured flow rate for each of the two time periods of the previous month on the basis of the leak determination time point to check the leak.

 In addition, the control unit of the present invention is characterized by identifying the leak by grasping the previous measured daily flow rate of the previous month on the basis of the leak determination time.

In addition, the control unit of the present invention is characterized by identifying the leak by grasping the total flow rate of a specific time period of the previous month on the basis of the leak determination time.

In addition, when determining the leakage in the control unit of the present invention, it characterized in that it further comprises a display unit consisting of a monitor, a printer or a plotter for displaying whether or not the leak occurred by the control unit and the location of the water pipe.

In addition, the display unit of the present invention is characterized in that it comprises the position information of the water pipe, which is determined to leak in conjunction with the Geographic Information System (GIS).

It can also be output to a printer or plotter.

The database 12 is connected to the control unit 14, and the flow rate information detected by the sensing unit 10 and transmitted to the control unit 14 is stored in the database 12 by the control unit 14.

In addition, the database 12 stores the amount of usage measured on the settlement date of the customer entered through the input unit 19, and when the user of the customer is changed-when a person living in the house moves and moves out. Thus, the moving day and moving day information and the measured value of the flow meter are stored.

The database 12 may be provided as one mass storage device or may be provided using one or more storage devices.

The controller 14 estimates the estimated customer at the leak determination time calculated based on the flow rate information detected at the time of the leak determination time by the detection unit 10 and the flow rate information of the customer belonging to the corresponding area input on the settlement date for the specific area. Compared with the total usage, it is arranged to determine a leak when the comparison results out of the normal condition.

That is, the controller 14 may be configured at one side of the water supply pipe when the estimated total amount of used customer at the time of the leakage determination calculated based on the flow rate information of the customer belonging to the corresponding area input on the settlement date deviates significantly from the actually detected flow rate. It is determined that a leak is occurring.

In addition, when it is determined that a leak occurs at one side of the water supply pipe, the controller 14 proceeds with a detailed leak checking process to calculate a corresponding position of the water supply pipe.

In addition, the controller 14 is connected to the display unit 18, and when it is determined that the leak is determined, the control unit 14 is provided to output the leak point or the leak amount to the monitor, printer, plotter constituting the display unit 18.

The control unit 14 is connected to the input unit 19 and is provided to be displayed through the display unit 18 when the user inputs identification information of the water supply pipe to determine whether the water supply pipe leaks and where the water leakage occurs.

On the other hand, the transmission unit 16 is provided to connect the detection unit 10 and the control unit 14, and is provided to transmit the flow rate information detected by the detection unit 10 to the control unit 14.

In addition, when the input unit 19 stores the data of the graphic information and the attribute information related to the water conduit constructed based on the geographic information system (GIS) in the database 12, the input information 19 stores the data of the graphic information and the attribute information. It is arranged to enter.

The input unit 19 may be provided in various ways. Preferably, the input unit 19 may be provided with a keyboard and a mouse so as to input the information in a graphical user interface (GUI) environment. The GUI (Graphical User Interface) is a user

It refers to a working environment where information is exchanged with a computer through graphics.

Referring to the operation of the integrated water management device configured as described above is as follows.

First, the user inputs and stores the flow rate value measured at the customer on the settlement date in the database 12 through the input unit 19, an example of which is shown in FIG.

As shown, the database 12 records the area number, flow meter number, customer name, usage amount, and settlement date.

In this case, in order to know the total flow rate used in the area, the total flow rate for the previous month should be determined based on the time of leak determination (specific day), and it is necessary to adjust this because the settlement dates are different.

To this end, the control unit 14 obtains the average daily flow rate value by referring to the flow rate value measured on the settlement date over several months, and then multiplies the average daily flow rate value by the remaining days for the previous one month on the basis of the leak determination time (a specific day). Find the total flow rate for each customer.

Referring to this example using the example shown in FIG. 4, when the settlement date of a customer is 15 days, the flow rate value measured on January 15 and February 15 measured to obtain the total flow rate for the month of March 31 Add up the flow rate and divide by the number of days to find the average daily flow rate. The controller 14 multiplies the average daily flow rate by the number of days (31 days) to obtain a total flow rate value.

On the other hand, the controller 14 calculates the average daily flow rate in March after dividing the flow rate value from March 1 to 15 by the number of days measured on March 15, and the number of days in the average daily flow rate in March. Multiply by (15 days) to get the total flow before the settlement date, and calculate the remaining flow by multiplying the remaining days (16 days) using the average daily flow value obtained using the measured value of about two months or three months and the total flow before the settlement date. The final total flow is obtained by adding up the total flow after the settlement date.

In addition, the controller 14 calculates the final total flow rate for all the customers belonging to the zone in this manner, and adds the final total flow rate to obtain the estimated total amount of the customer.

On the other hand, in the case of a house that has moved and moved to calculate the estimated total consumption of the consumer as described above, there is a calculation difficulty. For this purpose, it is based on the average daily water consumption by the Ministry of Land, Transport and Maritime Affairs or The average flow rate for the month can be obtained and the total flow rate can be calculated based on this.

For this purpose, a mobile furniture reference table is stored in the database 12. The mobile furniture reference table records an area number, a flow meter number, a customer name, a usage amount, a settlement date, a moving date, and an moving date as shown in FIG. It is.

At this time, if the moving day is earlier than the day for calculating the flow rate, the controller 14 may not know the usage of the newly moved furniture.

Therefore, in order to solve this problem, the control unit 14 may not know the actual usage of the moved household since the settlement date is far after March 20, which is the date of moving, as shown in FIG. 6.

Accordingly, the control unit 14 calculates the daily average water consumption of one household provided by the Ministry of Land, Transport and Maritime Affairs from 20 to 31 on the date of moving, or calculates and reflects the daily average water consumption of the month over the years of the household. Calculate the flow rate from the day of the move to 31 days.

 On the other hand, when the controller 14 obtains the total used flow rate of each customer belonging to the corresponding area and thus estimates the total used amount of the customer in the corresponding area, the control unit 14 detects and stores in the database 12 the corresponding area stored in the database 12. If it is less than a certain ratio compared to the flow rate measured by the installed flowmeter (when it is less than a certain ratio by the estimated total consumption / measurement total consumption), it is judged that a leakage occurred in the area.

As an example, looking at the process of determining the leak of the 1 zone belonging to the manastone pressure station in the water supply pipe network shown in Figure 2, first, the flow rate measured by measuring the flow rate in the detection unit 10 installed at point A and point B, the control unit ( 14) is received and stored in the database (12).

Then, the controller 14 obtains the total flow rate of households belonging to the corresponding area based on FIGS. 3 and 5 to obtain the estimated total consumption of customers, and then compares the total flow rate measured and stored above, and the ratio is equal to or less than a predetermined ratio. In some cases (when the calculated flow rate becomes less than 60% of the measured flow rate), it is determined that there is a leak.

Subsequently, the controller 14 performs a precise leak check process to check whether the corresponding water pipe leaks.

This precise leak check process is performed through various methods, for example, the control unit 14 performs a comparison with each other to obtain a specific time flow rate for the water pipe.

For example, the control unit 14 obtains a flow rate ratio between 3-5 AM and 6-8 PM, and determines that there is a leak on the day if there is a section in which the calculated flow rate rapidly increases.

Referring to FIG. 7, as can be seen from the graph, the contrast is expected to be flat as in the graph a, but it may be determined that there is a rapid leak on the date when it is projected as in the graph b.

As another method, the controller 14 may determine the daily average usage, and determine that there is a leak in the corresponding day when the daily average usage rapidly increases at a specific time.

Referring to FIG. 8, as can be seen from the graph, it can be observed that the daily average amount of use is not changed drastically, but increases rapidly at 25 days, and a leak occurs at this time.

As another method, the controller 14 may determine the leakage based on the change of the total flow rate in a specific time period.

At this time, the specific time zone used may be, for example, between 9 am and 12 am with a lot of water and sewage construction, or when there is an underground construction nearby, a change in the total flow rate may be found.

Referring to FIG. 9, if a sudden increase is observed by observing a change in the total flow rate according to a date from 9 am to 12 am, this may be considered a leak day, and it may be determined that there is a leak on the 15th day. Can be.

9 is a flow chart of the integrated water management leak management method according to an embodiment of the present invention.

Referring to the drawings, first, the control unit receives a flow rate value measured in real time from a plurality of sensing units installed in necessary areas such as large blocks, heavy blocks, and small blocks of a water pipe of a water pipe network and stores them in a database (S110). ).

In addition, the control unit refers to the estimated flow rate (total consumption) used by the customer in the previous month on the basis of the leak determination time (specific day) by referring to the flow rate measured by the flow meter of the customer stored in the database by the user through the input unit. ) Is obtained (S112).

To this end, the controller obtains the estimated total customer flow rate by referring to the flow rate value of the settlement date of each customer stored in the database and the flow rate value of the delivery or delivery thereof.

In addition, the control unit calculates the amount of used households with reference to the mobile furniture table stored in the database and calculates the estimated total customer flow rate based on this.

On the other hand, the control unit calculates the total flow rate supplied to the previous month's zone on the basis of the leakage determination time (specific day) based on the flow rate information measured by the sensing unit, and then compares the estimated total customer flow rate calculated as used by the customer. To calculate (S114).

That is, the controller calculates the ratio by dividing the estimated total customer flow rate calculated as used by the customer by the total flow rate supplied to the previous month's zone on the basis of the leak determination time (a specific day).

Then, the control unit determines that the ratio of the estimated total customer flow rate calculated as used by the customer for the measured flow rate information is below a predetermined level, for example, if it is 60% or less, it is necessary to confirm the leak (S116).

Of course, the control unit determines that the ratio of the estimated total customer flow rate calculated as used by the customer for the measured flow rate information is a predetermined level or more.

On the other hand, if the ratio of the estimated total customer flow rate calculated as used in the customer with respect to the measured flow rate information is below a certain level, a precise detailed leak check process is performed, such a process proceeds as follows.

First, the control unit grasps the flow rate measured for each time zone in two specific time zones (S120).

Then, the control unit compares the flow rates measured at two specific time periods to calculate the flow rate ratio for each time zone (S122), and determines whether there is a sudden rise section in the calculated flow rate ratio (S124).

As a result, the controller determines that there is a leak when there is a sudden rising section, and performs a leak determination (S126), and informs the administrator of the result through a display unit or an SMS text message and ends (S128).

On the other hand, the controller determines the daily average flow rate measured a month ago as another method for checking leakage (S130), and determines whether there is a sudden increase in the measured daily average flow rate a month ago (S132).

As a result of the determination, if there is a sudden rising section, it is determined that there is a leak (S134), the determination result is output to the display unit, and the text message notifies the manager of the position and the amount of leakage and ends (S136).

Another method of checking for leaks is to check the measured daily flow rate at a specific time zone a month ago (S140), and then check whether there is a sudden change in the measured flow rate at the identified time zone (S142), and if there is a sudden rise in a specific time zone, it is determined as a leak. (S144), there is a method of outputting the determined result and ending (S146). Using this method, it is easy to detect leaks when certain situations occur.
