1 is an explanatory diagram showing a schematic configuration of a water pipe network operation management system according to an embodiment of the present invention.

Referring to FIG. 1, a water pipe network management system according to an embodiment of the present invention includes a real-time pipe network analysis module 110, a water management module 120, a water quality management module 130, a crisis management module 170, and the like. It can be seen that the configuration.

The real-time pipe network analysis module 110 sets a block of the pipe line based on the water supply pipe network diagram and real-time data, and performs a function of identifying a pipe network behavior state including a flow rate and a water pressure of each pipe line.

Here, the waterworks pipe network is created based on the Geographic Information System (GIS), and it may be preferable that the entire area displayed on the waterworks pipe network can be divided into hierarchical blocks such as large, medium, and small to be manageable.

As a sensor for detecting the flow rate, the water quality and the water pressure of each pipe, any conventional sensing sensor may be applied.

The quantity management module 120 leaks through flow rate analysis for each block by using pipe network behavior state information such as flow rate determined through the real-time pipe network analysis module 110 or flow rate information collected through a sensor or the like individually. Perform monitoring functions. That is, data such as flow rate collected through various sensors, information collection devices, etc. are aggregated to provide information such as real-time supply flow rate and flow rate for each block, and the leakage amount is determined by various algorithms.

At this time, the algorithm for determining whether the quantity management module 120 leaks and calculates the amount of leakage according to the present invention may be variously applied. In the embodiment of the present invention, the difference analysis or trend of the minimum night flow rate (MNF) or the inflow flow rate is applied. It may be more desirable to use methods such as by using analytical or by setting a threshold of the minimum flow rate at night.

For example, when using the difference analysis of the minimum night flow rate, if the average value of the minimum night flow rate of the first week before the judgment day is 20 m 3 or less, when the average value of the night minimum flow rate of the week 1 before the judgment day is exceeded, or If the average value is more than 20m3, separate leakage judgment logic is executed when it exceeds 110%, or if the average value of the 1st weekly supply flow rate before the judgment day is less than 20m3, if it exceeds 120%, and the judgment day In the case where the average supply flow rate of the first week before the reference is 20 m 3 or more, a method such as executing a separate leak determination logic may be applied when it exceeds 110%.

Here, the reason for calculating 110% or 120% of the average value for one week on the basis of 20㎥ is to exclude the slight change, and specific values such as 20㎥ or 110% or 120% are just one example. It will be apparent to those skilled in the art that the present invention is not necessarily limited thereto.

At this time, it is obvious that any conventional leak amount calculation method may be applied to the leak amount calculation method applied to the embodiment of the present invention. In addition, the leak determination logic may also be applicable to a variety of conventional leak determination logic, for example, an algorithm such as the following equation may be applied.

[MNF]-Today's weekly average before today (or count)]>

[Average value before week 1 (count)-2 week average before today]

That is, in the case of applying the same logic as in the above equation, if the condition is satisfied, the value 'Count' is generated in the 'current leak count', and when the corresponding cumulative count is '3' or more, it is determined as 'leak'. The method may be applicable. However, it is obvious that the present invention is not necessarily limited thereto.

In addition, the quantity management module 120 may have a function of automatically generating an alarm such as an alarm sound when it is determined that leakage occurs by the leakage determination logic as described above.

The water quality management module 130 selects and presents a water quality monitoring point by using pipe network behavior state information identified through the real-time pipe network analysis module 110 or flow rate information individually collected through a sensor, and the corresponding point. It may be configured to perform a real time water quality monitoring function.

Here, the selection of the water quality monitoring point may be configured to be made in consideration of conditions such as water quality related complaint frequency information and facility importance weight in addition to basic information such as flow rate contribution information and residence time information.

At this time, the flow rate contribution rate refers to the ratio of the contribution rate of the other nodes to the reference node with respect to the flow rate of the contribution node to the total flow rate flowing into the reference node. That is, a node with a high flow rate contribution means that a lot of flow rate passes, and thus, a damage effect can be greatly affected when breakage or water pollution occurs.

That is, the water quality management module 130 selects a monitoring point using the information when the residence time or flow rate is determined through the information on the network network behavior, and sets the high and low reference standards for the monitoring point and analyzes the water quality data pattern. If it is determined that there is a problem with the water quality, then the exact location of the alarm or alarm occurrence and the water quality problem is identified and displayed on the GIS, and the detailed status analysis data of the corresponding water quality is provided. And the like.

In this case, the water quality management module 130 analyzes the frequency of water complaints for each block, manages the details of the complaints, and displays them on a GIS, or predicts residual chlorine through pipe network analysis. It can be done further. In other words, whenever a complaint related to water quality occurs, a detailed complaint history and the like may be written and displayed at a corresponding point on the GIS, and thus, the cumulative record may enable automatic confirmation of the frequency of complaints.

Here, the water quality incidents that can be managed by the water quality management module 130 may include a lack of residual chlorine, an excessive amount of residual chlorine, a rust generation, or a generation of microorganisms or foreign substances. Naturally, it can be different.

The energy management module 140 may perform a function such as displaying the real-time energy status of each pump existing in the water supply network using the network network behavior state information obtained through the real-time network analysis module 110. . That is, for each pump appearing on the GIS, information such as flow rate, efficiency, and power amount can be grasped in real time, and performance of energy consumption can be predicted through pump simulation. Can provide an effect.

The demand forecast management module 150 collects data generated through the real-time pipe network analysis module 110, the quantity management module 120, the water quality management module 130, or the energy management module 140, and is linear and nonlinear. It can perform the function of presenting daily and hourly demand forecast by algorithm. In other words, based on the data collected and accumulated through the real-time pipe network analysis module 110, water management module 120, water quality management module 130 or energy management module 140, by applying a variety of conventional analysis algorithms By analyzing, it is possible to predict and present various demands for each block by day and hour.

Here, when an error occurs in the data collection process due to communication and system failure, the demand prediction management module 150 corrects the data of the error occurrence section by using real-time collected data in a normal state where the failure does not occur. You can do it.

In addition, a normal data correction process may be applied, for example, to set a period to be recollected → to delete real-time data in a system for a specified period of time → to re-collect real-time data → 1-hour integrated data correction (recalculation) → 1-day integration Data correction (recalculation of daily accumulated data based on 1 hour integrated data) → Minimum night flow rate correction based on real time data → Re-run flow rate analysis based on supply volume during the recollected period → Corrected minimum flow rate Based on the daily supply, processes such as restarting the leak monitoring process may be applied. At this time, it is obvious that the above correction process is only one exemplary process applicable to the embodiment of the present invention.

In addition, the water supply network operation management system of the present invention registers each control method for a plurality of pressure reducing valves to maintain the appropriate pressure for each block, the hydraulic pressure management module 160 for monitoring the real-time measured pressure of the individual pressure reducing valves It may be provided.

The hydraulic pressure management module 160 selects and registers an appropriate pressure change width of the pressure reducing valve and registers the pressure on the GIS for the pressure reducing valve that detects a pressure change that is out of the appropriate change range and generates an alarm or alarm. And so on.

Crisis management module 170, if the occurrence of a pipeline accident or a water quality accident is confirmed through the water quality management module 120 or the water quality management module 130, the real-time identification and prediction of the singular or water quality incident area according to this To automatically suggest the best response.

In other words, when a pipeline accident occurs, the accident occurrence point is selected to search for and present a shutoff valve, analyze and present a single cutoff region by the cutoff valve, and determine whether a bypass line exists to minimize the single cutoff region. If there exists a bypass pipeline that satisfies this, it is possible not only to perform the function of presenting it, but also to perform a function such as comparing and analyzing the singular areas before and after water supply through the bypass pipeline and displaying them on the water supply network.

In addition, the crisis management module 170 may present the impact range of the water quality accident using information such as the time of occurrence of the water accident or the watershed of the occurrence of the water at the time of occurrence of the water accident, and at the present time and the spread area at the time of the completion of the action. Accurate analysis can be performed to display on the waterworks pipe network.

More detailed functions related to the crisis management module 170 will be described later through separate drawings.

In addition, the water pipe network operation management system of the present invention, the real-time pipe network analysis module 110, water management module 120, water quality management module 130, energy management module 140, demand forecast management module 150, Using various data generated through the hydraulic pressure management module 160 or the demand crisis management module 170, an operation report generation module 180 may be further provided to automatically generate daily and monthly operation reports.

In the operation report generated through the operation report generation module 180, various information such as supply amount per block, minimum night flow rate, specificity per block or past history, etc. may be recorded.

On the other hand, the water supply network operation management system according to an embodiment of the present invention, using the network network status information obtained through the real-time network network analysis module, etc. to select the re-chlorine input point to perform the function of selecting and presenting the re-chlorine point Module 190 may be further provided.

Functions such as automatically presenting the point of administration and dosage, and the like.

In addition, the present invention may further include a tariff section selection module 195 for performing the selection presentation function of the tariff section. That is, the tariff section selection module 195 automatically selects the tariff required sections based on criteria such as flow rate information, residence time information, and complaint information regarding water quality, and displays them on the screen or generates an alarm. It will perform the function. When the tariff section is selected and presented by the tariff section selection module 195, the tariff cleaning operation may be performed by a method such as adjusting the pressure of the section through a manager's instruction.

In this case, when the operation report generation module 180 generates daily and monthly operation reports, it is natural that data generated through the rechlorination point selection module 190 or the tariff section selection module 195 may also be used. Do.
