Currently, the management of tap water pipe network is intensively investing in expanding the water pipe network to satisfy the water supply of customers, replacing old pipes, regenerating or replacing meters, but the leak rate increases and flows due to aging of water pipes and drain pipes and poor maintenance of facilities. Yields are stagnant.

In recent years, the database has been steadily built by exploration and survey of tap water pipe networks, but due to the absence of a water tap pipe method to effectively manage it and the operation management system using it, unnecessary singular measures have been implemented, and the demand for water supply by pipe network analysis Diagnosis is not made.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art to which the present invention pertains can easily practice. The present invention can be implemented in many different forms and is not limited to the embodiments described herein.

In order to clearly describe the present invention, parts irrelevant to the description are omitted, and the same reference numerals are assigned to the same or similar elements throughout the specification.

In addition, since the size and thickness of each component shown in the drawings are arbitrarily shown for convenience of description, the present invention is not necessarily limited to what is illustrated.

Also, in the specification, when a part “includes” a certain component, it means that the component may further include other components, not to exclude other components, unless otherwise stated.

1 is a flow chart of a water supply pipe network management method according to an embodiment of the present invention.

Referring to FIG. 1, a step (S10) of setting a subcatchment in a tap water pipe network partitioned into a unit block and inputting data including a water pipe and a valve in the unit block may be included.

The unit block may be divided into a large block, a medium block, or a small block. For example, a large block or a medium block may be set around the water purification plant, and a small block may be set around the drainage basin. In Seoul, for example, the Amsa Water Purification Plant or Gangbuk Water Purification Plant can be a large block water purification plant. The large-block water purification plant supplies water to the medium-block water purification plant with a water pipe. The medium-block water purification plant is a drainage main pipe with a diameter of 400 mm or more and is connected to a plurality of small blocks. The small block is connected to the drainage pipe, and a number of houses are connected. Since the elevation of the terrain is different, the position of each unit block is different. Accordingly, the heights at which water pipes are installed are different, and the flow rates are also different.

Data input to the unit block can be installed not only water pipes, but also pumps, flow meters and valves for pressurization.

Waterworks network maps can be displayed on the map. For example, the tap water network may be provided with data from a Geographic Information System (GIS) server. GIS is a system in which all types of geospatially referenced information are stored. Data on tap water network maps can be displayed on 3D, 2D maps or satellite maps provided by GIS.

The subwatershed of the waterworks network for maintenance may be a unit block pre-divided on the map. As another example, it may be a randomly selected zone in the unit block. For example, a large-scale development zone such as residential land development may form one unit block. As another example, in the case of a construction for maintenance or replacement, an old water supply pipe in an existing unit block may be selected as an arbitrary area for construction.

The water supply pipe may include a very small pipe having a diameter of 100 mm or less, starting from a drainage main pipe having a diameter of 400 mm or more. These water pipes are selected in consideration of the distance to be transported, the number of customers, and the altitude of the terrain, and the water pipes are formed in a lattice form in a unit block or are complicatedly connected to each other to transmit water to the customers.

During the maintenance period of the water supply pipe, the singular measures of the customer are inevitable. Customers in the subcatchment established for maintenance management may be singular. Accordingly, in order to prevent unnecessary singular measures of a large number of customers, it is very important to establish a subcatchment and thus a singular plan.

To this end, it may include the step (S20) of displaying the direction of movement of the water in the subcatchment on the waterworks pipe network. For example, the valve to be controlled according to the direction of water supply movement in the subcatchment may be different. Since the water pipes are complicated and diverge in various directions, it is very important to select and control the valve for the minimum number of stages in the subcatchment. For example, it is possible to cut the entire unit block by controlling the valve of the drainage main pipe, but for reducing the number of unnecessary stages and for the convenience of the customer, the valve should be selected to analyze the water supply movement direction and select the minimum customer in the watershed. .

Accordingly, it may include a step (S30) of analyzing the constant movement direction, displaying a valve capable of stopping the constant movement in the subcatchment, and selecting a valve to be blocked among the displayed valves (S40). .

Visually displayed valves can be more easily selected by the administrator. That is, the administrator can select a valve to be blocked after confirming once more that it is appropriate to perform a single step by shutting off the visually displayed valve. Inadvertent singular action can cause physical and psychological damage to the consumer, so the manager can select the valve to be blocked.

Next, it may include a notification step (S60) of notifying the operation information to the customer to be cut off by the valve to be blocked. By notifying the customer of the operation information in advance before construction, the customer can take precautions against any inconvenience or damage that will occur due to a single action. In addition, the customer can postpone the construction schedule by requesting the manager if an unexpected event occurs before the action is taken. As another example, when an unexpected request or event occurs in the consumer, the administrator may consider a method of blocking the unmarked valve to supply the consumer with constant water while bypassing the constant for construction.

As described above, the method for managing a water pipe network according to an embodiment of the present invention establishes a construction plan while setting a subwatershed in the water pipe pipe network in advance, and minimizes the inconvenience and physical and mental damages of the customer by setting the number of customers to be taken to a minimum. In particular, it has the advantage of being able to flexibly respond to unexpected events of the customer by notifying the customer of the operation information before maintenance.

The valve selection step may include a step (S42) of selecting a water pipe to be constructed in the subwatershed and a step of analyzing a valve to be blocked by analyzing the constant movement of the selected water pipe (S44). For example, a subcatchment can be set to an area as well as a subcatchment to be selected when selecting a water pipe to be maintained. In this case, the valve to be blocked may be displayed by analyzing the constant movement of the selected water pipe. In general, maintenance of water pipes is carried out along connected water pipes, so there is a possibility that unnecessary steps will be taken when selecting a valve to be blocked by zoning. Accordingly, it is possible to select a valve for a minimum number of steps by directly selecting a water supply pipe requiring maintenance. However, the distribution of the customers to be singulated by the valve selection does not necessarily coincide with the connection direction of the water supply pipe, and may be displayed as a subcatchment including the distribution position of the customers.

The valve to be closed is not located within the established subcatchment, but may be located outside the subcatchment. This is because the distribution of the water supply pipe and the distribution of the consumer do not match. Accordingly, a customer that is cut off by the shutoff of the valve may also include an area outside the subcatchment. Therefore, the operation information for the single action should be notified to the customer based on the valve to be blocked. For example, the operational information for a singular measure may be a subwatershed, construction period, and construction purpose. That is, the construction period of the waterworks subject to construction can be entered to inform the operation information including the construction period. In addition, when intermittent singularity is made, information on the singularity time may be notified.

2 is a flow chart of a water pipe network management method for extracting water leakage, aging and environmental information of a water pipe network according to an embodiment of the present invention.

Referring to FIG. 2, extracting daily water demand for a subwatershed on a per day basis, database of customer usage by watershed using water rate data, and calculating the weight of the subwatershed based on daily demand and water consumption by subwatershed (S51) It may include.

For example, depending on the consumer price, the amount of water used may be large. For example, in a commercial facility that mainly uses water, the amount of water used may be much larger than that of an ordinary household. Therefore, the weight of the subwatershed is calculated and reflected based on the usage amount of the customers in the set subwatershed.

It may include the step (S52) of database number for each subwatershed. That is, information on the lot number is constructed so that the unit block displayed on the map can correspond to the site. It may include a step (S53) of estimating the amount of water using the number of each subwatershed and the daily demand and the weight of the calculated subwatershed. That is, the amount of water used can be estimated through pipe network analysis.

For example, the water supply pipe can be composed of a water intake pipe that collects raw water and sends it to a water intake, and a water supply pipe from a water purification plant to a water drainage can be composed of a water supply pipe, a water supply pipe that is branched from the water supply pipe and a water pipe that is branched for the purpose of drainage, and continues to the water supply pipe. have. This water pipe can estimate the flow rate through pipe network analysis. Therefore, the water pipe network can be designed based on the estimated and calculated flow rates. Since the flow of constant water in a sealed pipe is very variable, the weight of the subwatershed is reflected and the amount of water used in the required area is estimated using the daily demand and water rate data of the customer. Subsequently, the method further includes comparing the estimated usage amount and data measured from the customer (S54). That is, it is possible to set the management direction of the tap water network by comparing the measured amount of water and actual measured data according to the theory.

Next, through the step of comparing, it may include the step of analyzing the leakage of the tap water network and reviewing the abnormality (S55). In addition, through the step of comparing, it may include the step of estimating the age of the tap water network (S56).

For example, as a result of comparing the estimated and calculated usage quantity with the weighted data and the actual measured data, if the actual measured data has a very large error between the estimated usage quantity, the leak of the waterworks network may be suspected. , You can estimate the aging degree. For example, it can be judged that the range of the error increases gradually with the passing of the year, which proves that the aging degree increases. Therefore, maintenance management of the subwatershed can be planned.

In addition, it may include a step (S57) of extracting the environmental information through the input data and data measured from the customer. For example, if the constants sent from the water purification plant contained hazardous substances within the allowable value, but if the data measured at the consumer contains harmful substances exceeding the allowable value, infer not only the damage to the water supply pipe in the subwatershed, but also infer environmental information. can do. Therefore, it is possible to infer and understand the environmental information of the subcatchment by comparing the input data with the data measured at the customer.

3 is a configuration diagram of a water supply operation management system according to an embodiment of the present invention.

Referring to FIG. 3, the water supply operation management system 100 may include an input unit 10, a selection unit 20, a display unit 30, an analysis unit 40, and a transmission unit.

The water supply operation management system 100 may be a program operated on a computer. For example, a map of a water supply area transmitted through map information and a plurality of unit blocks for dividing the map may include an input unit 10 for inputting tap water data and the location of the tap water pipe. Through the input unit 10, it is possible to input waterworks data such as the number of customers, the water rate data, and the number of harmful substances in the constants to be transmitted. Such data can be inferred from the analysis unit 50 for leak prediction, aging evaluation, and environmental information, as compared with data measured at the end-user audience.

The input unit 10, the laying year of the water supply pipe and the construction record can be input. That is, as well as data for new expansion, construction records due to maintenance can be input and managed.

You can select a subwatershed within a unit block. Singular actions can be made to selected watersheds, and waterworks operation information, such as maintenance, can be transmitted to customers in selected watersheds.

The selector 20 may not only set a subwatershed as a range, but also select a water supply pipe that is a maintenance management target, and a watershed range including a water supply pipe subject to construction may be set. Since the distribution direction of the water supply pipe and the distribution of the consumer do not coincide, setting the range of the subcatchment can be different each time. Therefore, a more optimal subwatershed can be selected.

When the subcatchment is selected by the selection unit 20, the display unit 30 may analyze the valve connected to the water supply pipe and display the valve. That is, when the subcatchment is set, it is possible to indicate a valve to be controlled for a single step action inside the subcatchment. The displayed valve visually informs the manager, and the manager can determine whether to shut off by reviewing the displayed valve once more.

Through the transmission unit 40, it is possible to notify the operation information to the consumer. Prior to construction for maintenance, information on the construction period, number of stages, and purpose of construction can be notified to the consumer to minimize inconvenience and damage to the consumer. In addition, by notifying the consumer in advance as described above, if the singular action is not possible due to the unexpected accident of the customer, the construction plan is changed or the subwatershed is changed to avoid the singular action of the customer by bypassing the plan for construction. Can stand.

4 is a flowchart illustrating a method of setting a water pipe network model applied to FIG. 1.

Referring to FIG. 4, a method for setting a water pipe network model may select a theoretical model, compare it with data measured in the field, and predict a leak amount and a corresponding leak area to set an application model used for the water pipe network.

First, an initial model for a waterworks pipe network may be constructed (S101), and may include comparing the calculated value and water pressure according to the constructed initial model (S102). For more systematic waterworks network management, an initial model is built to manage the waterworks network based on theoretical calculations. For example, the initial model provides data on the forecasted water pressure considering the drainage flow rate in the region to be analyzed for one year, the consumption of each individual customer in one year, and the inflow / flow rate data of the subwatershed and the numerical topography and the height of the terrain. Can be built using

In addition, condition values and weights can be calculated and set by calculating the type of water pipe, the diameter of the water pipe, whether the inner or outer surface of the water pipe is covered, and the type of soil. In addition, weights may be differentially applied in consideration of setting values of installed equipment for pressurization and decompression. These weights can be set according to the basic knowledge of network analysis and the components and quantity of facilities in the area.

According to the initial model, the theoretically calculated water pressure is compared with that of the representative area. The representative area may be a unit block or a subwatershed established within the unit block.

Thereafter, the influence factor of the hydraulic pressure fluctuation is analyzed. (S103) The influence factor can be analyzed by comparing the theoretical calculated value with the actual measured water pressure. For example, the data entered in the initial model is reviewed, and the operation status of facilities and the presence and absence of losses in pipelines are analyzed. As described above, through the analysis of the influence factor, the initially constructed model can be corrected to set an application model more suited to reality.

Next, the daily average amount of use is recalculated (S104). The supply quantity is equal to the sum of the imposed quantity, the anhydrous quantity and the invalid quantity. Therefore, considering the flow rate, it is possible to calculate and grasp the anhydrous amount and the invalid amount (S105). If there is a large amount of anhydrous or invalid water, it can be considered that there is a leak in the water supply pipe, so it is easier to learn information about the water supply pipe network.

Thereafter, the operation of the water supply pipe network facility is reviewed (S106). For example, the facility may be a facility for pressurization or decompression, and may be a valve for a water pipe. In consideration of the recalculated daily average water use, it is possible to predict or grasp the anhydrous or invalid water quantity, and to review and carry out whether or not the valve is pressurized or depressurized.

In addition, it may include the step (S107) of evaluating the tap water network. Predicting whether anhydrous water or invalid water can be used, it is possible to evaluate the aging degree of a waterworks network. For example, if the number of anhydrous or invalid amounts of water has risen compared to the reference date, it can be managed by numerically evaluating it according to the section of the rising value.

Based on the initial model, it is possible to analyze the influence factors, recalculate the daily average usage, review facility operation, evaluate the buried pipeline, and calculate the applied model that corrects the initial model (S108). Since the topography differs depending on the area where the water supply network is managed, a uniform model cannot be applied, so the process for selecting an application model from the initial model selection is the most important. Through this process, more accurate and systematic waterworks network management may be possible.

Although the present invention has been described through preferred embodiments as described above, the present invention is not limited to this, and the present invention shows that various modifications and variations are possible without departing from the concept and scope of the following claims. Those in the field of technology to which they belong will readily understand.
