Description

Water pipe safety management system using web application {INTEGRATION SYSTEM FOR WATERWORKS PIPE ASSET MANAGEMENT UTILIZING WEB APPLICATIONS}

The present invention diagnoses the stability of facilities through operation support and precise diagnosis of facilities based on water pipe information among underground facilities. It relates to a water supply pipeline safety management system using a web application that evaluates and provides reference data for maintenance dominance ranking through disaster situation simulation results.

Currently, domestic underground facilities are growing quantitatively and qualitatively, but due to the absence of specialized water management companies and lack of expertise at the level of domestic privatization, even though underground facilities are social infrastructure, asset management cannot be widely applied. The introduction of service levels for setting maintenance goals for underground facilities has hardly been implemented, and asset management in local governments is based on a simple system such as regular inspection of social infrastructure, computerization of facilities, and history of facility replacement and repair. As such, there is no mid-to-long-term plan.

Accordingly, recent research on the introduction of an asset management system for social infrastructure has been actively conducted in Korea. In particular, in the case of an underground facility, the social and environmental costs that occur in case of asset failure are the daily maintenance costs. Or, since it has a characteristic that is much larger than the maintenance cost, it is essential to apply the asset management technique to switch to the preventive maintenance system.

In the case of water supply pipelines, proper management is important because it is directly related to disaster prevention of urban floods, which are frequently occurring recently in the event of an accident. The aging of the water supply and sewage pipe networks is progressing mainly in large cities where the introduction of modern waterworks was made in the early stages, reducing the function of the overall water supply and sewage system. However, unlike other general public facilities, the water supply and sewerage pipe network has great difficulties in operation and maintenance due to the peculiarity of being buried underground. is often difficult to

Accordingly, it is necessary to expand and apply it to the decision-making system for rational decision-making of maintenance and repair plans. The maintenance and improvement of the water supply network requires a huge budget and time, and some decision-making techniques for the maintenance and improvement of the water supply have been proposed, but the linkage with the systematically established asset management system is unclear, so the utilization is low. the current situation. In addition, there is no prediction in the disaster situation at all.

Therefore, for the proper operation and maintenance of water supply facilities, the introduction of an integrated management system that combines systematic asset management techniques and decision-making methods and a water pipe safety management system using a web application including a disaster situation prediction scenario I need this.

The present invention diagnoses the stability of facilities through operation support and precise diagnosis of facilities based on water pipe information among underground facilities.

After setting the system management menu as described above, it is possible to check the overall details of the water supply pipe safety management system using the web application through the water supply and water pipe safety management system menu.

On the other hand, the overall matter of the water supply pipe safety management system is a data management system that stores CCTV investigation and visual inspection data through self-propelled vehicle exploration of the water supply pipe and performs defect coding, and utilizes the information of the data management system to analyze risks a risk assessment system that performs and evaluates risk priorities, a service evaluation system that analyzes service levels and sets service goals, and a maintenance cost prediction system that predicts the size of maintenance costs by analyzing life cycle and replacement costs; A comprehensive maintenance priority evaluation system that evaluates the overall maintenance priority based on the results derived from the risk evaluation system, the service evaluation system, and the maintenance cost prediction system, and an asset management system that establishes a water pipeline maintenance and budget plan It is desirable to derive it based on an integrated system for asset management of water supply pipelines.

The contents of the integrated system for asset management of water supply pipelines as described above are as described in FIG. 7 .

Specifically, the data management system receives CCTV image information of the water and sewer pipelines using the self-propelled vehicle and information through visual inspection, and proceeds to code the defects in the water and sewer pipelines to calculate the defect codes, defect grades, defect scores, and status grades. have.

The defect code is determined according to the defect item, and the defect item is a generic term for internal and external defects found during facility investigation. It may include sedimentary soil, deformation of the pipe diameter, leakage of pipe joints, steps in joints, gaps, breakage, and the like.

The defect grade is divided into a total of three grades for classification by scale of defect items, and the grades are represented by A, B, and C, where A is severe, B is moderate, and C is mild. is evaluated as

On the other hand, input and output of all data, such as information or defect information, received through investigations in the data management system is possible, large-capacity data management is possible, and the function of creating a report on the results of the investigation is provided. In addition, it supports inquiry information list inquiry and detailed inquiry. The investigation result report may include basic information and contents of the investigation result.

In addition, the data management system can be provided with information supported by GIS such as type, location, depth, and year of burial in connection with GIS (geographic information system).

Meanwhile, the risk evaluation system evaluates the overall risk priority by using the structural risk evaluation result, the mathematical risk evaluation result, and the weighting coefficient data.

The risk priority evaluation is calculated by applying environmental importance (weight) to the severity score, and the basic unit of analysis is the individual unit between the manhole and the manhole.

The risk evaluation system calculates the defect score and risk grade for each division based on the defect score and weight coefficient data according to structural and mathematical evaluation. The risk grade calculates the degree of defect on a scale of 1 to 5. Based on the calculated contents, the comprehensive risk priority is evaluated and a list is provided.

That is, the risk assessment system retrieves and calculates the environmental importance specifications from the water and sewer pipeline attribute tables of GIS, and the risk priority decision considers the risk score (structural re-average score + hydraulic average score) and weight coefficient data for each conduit is calculated, and the result is output as a risk score and risk grade. In addition, risk priorities are expressed in a chart format.

The structural and mathematical analysis results and priority setting results are stored in the system, the evaluation results can be displayed based on GIS, and the results can be downloaded in Excel.

On the other hand, the data management system and the risk management system, the first step of obtaining defect information by analyzing information obtained through exploration by putting a self-propelled vehicle inside the water supply pipe, and using artificial intelligence for defect and risk analysis A second step of analyzing information to obtain risk information, a third step of modeling the water and sewer pipelines in three dimensions using the defect information and risk information, and a fourth step of continuously outputting the results of the modeling through a screen It is preferable to proceed to include.

In addition, steps 1 to 4 may all be performed through an information analysis program. In the first step, the information analysis program extracts, cuts, and joins the image information obtained through the self-propelled vehicle to create a development drawing, by applying a distortion correction technique to increase the accuracy of the defect information.

In addition, in the second step, location information may be displayed through a moving distance measuring system based on the moving distance and moving time of the self-propelled vehicle measured using the gear and communication cable of the self-propelled vehicle, and in the third step In , it is possible to form a three-dimensional drawing by using the moving distance of the self-propelled vehicle obtained from the preceding moving distance measuring system as the length of the pipeline.

In addition, in the fourth step, the position of the defective part of the modeled result can be enlarged, reduced, and rotated, and the output speed can be adjusted.

More specifically, in the present invention, it is possible to check the defect location information through the moving distance measuring system in step 1.

The system indicates the distance traveled by the self-propelled vehicle after a specific time after the self-propelled vehicle exploration starts, and location information can be obtained by using this. Based on the number of revolutions of the gear connected to the communication cable connected to the autonomous vehicle Calculate the moving distance of the self-propelled vehicle. Here, the communication cable is sufficiently hard and thick enough to measure the distance because there is no drooping or bending in the middle.

On the other hand, when the self-propelled vehicle starts exploration, the movement time is measured while the image is taken through the camera, and when the image is saved in the information analysis program, the movement time is also saved. have.

Therefore, if the moving distance measuring system that can know the moving time information stored in the image and the distance according to the moving time is used, the moving distance of the self-propelled vehicle when the image is taken can be known, and through this, the location where the image was captured can be known

In this way, it is possible to easily solve the repair and replacement work by accurately identifying the defect location of an invisible underground facility. In addition, when the location is measured in the same way as described above, the accuracy of location information is 90% or more, so it can be used very efficiently during maintenance and replacement.

Meanwhile, as described above, the information analysis program can be used in the overall process of steps 1 to 4. The information analysis program may display distance information on the development drawing including calculation or control means. This can be usefully utilized when forming the defect information and risk information into GIS.

In the second stage, it is possible to analyze defects and risks more quickly and accurately through an information analysis program using artificial intelligence.

The information analysis program using artificial intelligence makes a pipeline development drawing from video and images taken from the start point to the end point of the pipeline so that the information and defects of the defect can be enlarged and confirmed, and the defect from the time information displayed on the development drawing location information can be obtained, and at the same time, defects can be identified more accurately by qualitatively analyzing the defects in the pipeline. In addition, it is possible to know the overall risk score and risk grade through quantitative analysis per unit of pipeline, which can be an important indicator in determining maintenance, repair and replacement. That is, it is useful for asset management and safety management because it is possible to know the exact location of the defect, along with the severity of the defect and the resulting risk by analyzing the defect information and risk information of the defect from the development drawing of the pipeline.

On the other hand, in the present invention in the three-step process, it is possible to obtain a three-dimensional pipe shape.

In order to obtain a three-dimensional shape, the X-axis and Y-axis direction information of the distance information of the development drawing is extracted, and the Z-axis is the X-axis to be reconstructed in three dimensions by connecting it with a straight line to the ground where the facilities are buried at the center point of the pipe diameter located at the starting point of the exploration. Coordinate space consisting of , Y, and Z axes can be set.

The coordinate space sets the midpoint (0,0,0) at which the X, Y, and Z axes are orthogonal to the exploration starting point, and connects the points existing in the length corresponding to the radius of the pipe to the YZ plane from the midpoint to determine the pipe diameter. can create At this time, the midpoint becomes the central point of the tube diameter, and the length of the tube diameter cannot be a negative value because it is the diameter of the tube.

The moving distance of the self-propelled vehicle can be known from the moving distance measurement system, and since this becomes the length of the pipeline, the length is set as the end point, the end point of the pipeline is input to the X axis, and the A tube diameter is created by setting coordinates as much as the radius of the tube in the positive and negative directions of the Y and Z axes once. Finally, a three-dimensional drawing of a cylindrical shape is formed by connecting the tube diameters of the start point and the end point, and if the two-dimensional development plan of the present invention is covered on the cylindrical drawing, it can be reconstructed as a three-dimensional pipeline.

In addition, the modeling is modeled by matching location information, defect information, and risk information in response to each defect included in the pipe.

For example, when there is a defect for a leak in a pipeline, the defect includes the location, grade, and score of the defect, and the structural and hydraulic risk score, overall risk score, and environmental significance of the conduit in which the fault exists. All information about the defect is matched and modeled.

Accordingly, the user can click on a defect in the three-dimensionally modeled pipeline through the input/output device with the cursor. When a defect in the pipeline is selected, information corresponding to the selected defect is output.

In step 4, the three-dimensionally modeled pipeline can be continuously output and viewed as an image. In addition, the image can be qualitatively analyzed from various viewpoints by allowing the image to be adjusted according to the user's needs, such as enlargement, reduction, stop, and rotation.

On the other hand, the service evaluation system performs a function of setting a reasonable goal in both directions through a gap analysis between the service level from the customer's point of view and the service level from the manager's point of view. Here, the service level is a level that the supplier can present at the current technical and budgetary level, and classifies performance indicators subdivided according to environmental, economic, social and cultural standards, and scores for each classification (1 to 5 points) is scored The service goal means a realistic and feasible target level that is proposed in the future in consideration of the service level requested by the user based on the current service level.

The service evaluation system performs LOS (Level Of Service) evaluation that integrates the service level goal from the customer point of view and the service level goal from the organizational point of view, and selects a reasonable target level through gap analysis of the service level goals. .

At this time, the service level from the manager's point of view is classified into grades by engineering the service scale for each zone and sub-unit, and the service level from the customer's point of view is classified into grades by engineering the service level felt by the customer. As described above, the target level is adjusted according to the importance and population density of each facility by analyzing the gap (gap) in the results calculated by numerical and grade.

In order to analyze the gap, first, satisfaction with the current service should be calculated. In order to accurately grasp the satisfaction of customers and managers, a survey is conducted, and the survey result file is uploaded to the system. Afterwards, the service evaluation system inquires the survey results and civil complaint processing history, and calculates satisfaction from the customer's point of view and the manager's point of view through the status data and survey data.

The above satisfaction level can be calculated by quantifying the service level calculated from the importance of facilities according to the population density of each district and district and the current service satisfaction level according to the operation and management history, which is used when presenting a reasonable target service level in the future. .

In addition, the satisfaction level and the target service level may act as a weighting coefficient in the risk evaluation system, and thus a risk score may be calculated and reflected in the risk priority.

The analysis result performed by the service evaluation system is stored and can be inquired if necessary. Analysis results can be viewed by date and type, and status and investigation results, maintenance history, and treatment history can also be inquired.

On the other hand, the maintenance cost prediction system performs a probabilistic LCC (life cycle cost) analysis in consideration of the uncertainty of the basic data, and predicts the size of the maintenance cost required for each item of the water supply and sewage pipe. The basic data includes basic data of an analysis target, location information, traffic volume information and maintenance information and discount rate information, and the traffic volume information and maintenance information may be provided from GIS information.

Here, the cost required for maintenance and repair of each facility is calculated based on the basic data, and whether additional cost is calculated based on the traffic volume information is determined. In addition, the maintenance information is information about the past history, and calculates the period and cost of maintenance, repair, and replacement predicted in the future. In addition, the discount rate and the inflation rate are used when converting the future value, and the location information is used to calculate the user cost together with the applied unit price and the traffic volume in which the reference cost is converted into the future value.

In addition, the maintenance cost prediction system calculates the initial investment cost, maintenance cost and dismantling, disposal cost, etc. through LCC analysis, and the initial investment cost includes construction cost, design cost, supervision cost, compensation cost, etc., and the maintenance cost includes inspection cost, diagnosis cost, Includes maintenance, maintenance, and replacement costs.

The maintenance cost prediction system receives basic data, that is, basic information of the analysis target, analysis period, analysis name, analysis method, location information, traffic volume information, and discount rate information, to perform LCC analysis. The maintenance information of the analysis target is provided from the database. The maintenance information includes repair, reinforcement, replacement characteristic values and maintenance scenarios of facilities.

Meanwhile, in the present invention, it is preferable to select a probabilistic LCC analysis method in consideration of the uncertainty of the basic data. The probabilistic analysis method is an analysis method that sets probabilistic characteristic values that follow a constant distribution rather than a specific value for the basic data of LCC analysis and presents the analysis results as probability characteristic values by performing computer simulation based on this. Therefore, it corresponds to a more advanced methodology than a definitive analysis method.

The results derived from the maintenance cost prediction system are reflected in determining a budget securing strategy and establishing an asset management plan, and can be used for efficient maintenance and operation of water and sewage pipelines.

On the other hand, the comprehensive maintenance priority evaluation system establishes the most optimized maintenance priority by synthesizing the risk priority and maintenance cost calculated to establish the maintenance priority strategy. Specifically, through the risk priority and LCC analysis, the risk priority calculated by the product of the water and sewer pipe severity score reflecting the structural and mathematical defect score and the environmental importance (weight factor) reflecting the target service level derived from customer and manager questionnaire analysis By reflecting the derived life cycle cost and maintenance cost, the actual priority for comprehensive maintenance of water and sewage pipes can be derived.

The LCC analysis is the result of analysis from the perspective of periodic management and maintenance according to the life cycle of the facility, and the LOS evaluation determines the future service level through the gap between the planned service and service satisfaction between the provider and the user. purpose, and the risk assessment is a criterion for determining the actual degree of deterioration by identifying the actual condition and defect level of the current facility. The optimal maintenance priority is established by comprehensively judging all three items.

In this way, it is possible to present the system users with the comprehensive maintenance priorities of sewage pipes in the categories of dredging, partial repair, total repair, and replacement, which makes it possible to establish an easy and efficient annual maintenance plan.

In addition, when the exceptional emergency repair cost due to a sudden accident is exhausted, the maintenance priorities are rearranged, and the remaining budget and repairable range can be indicated accordingly. This can support mid- to long-term maintenance planning and efficient budget execution.

On the other hand, it is possible to implement the contents of the above-described integrated system for asset management of upper and lower sewage pipelines on the website through the upper and lower sewerage pipeline safety management system menu.

The approximate configuration of the water supply pipe safety management system menu is as described in FIG. 8 .

As described in FIG. 8 , the water supply pipeline safety management system menu may include small menus such as investigation, prediction menu, diagnosis, evaluation menu, general management menu, asset management menu, real-time monitoring menu, and the like.

The Investigation and Prediction menu can provide pipe network analysis and pipe network analysis history results.

Specifically, as shown in Fig. 9, it is possible to select a water supply area to perform the pipe network analysis. The pipeline of the selected water supply area is marked on the map. As shown in FIG. 10 after selecting the water supply power as above, when the scenario setting is clicked, a drought scenario or an earthquake scenario can be executed.

When a drought scenario is executed, the extent of damage according to the degree of drought can be simulated by adjusting supply and demand. At this time, in the case of supply, the decrease can be adjusted in 5% increments, and in the case of demand, the increase can be adjusted in 5% increments. Through the simulation as described above, it is possible to predict the degree of drought damage of the facility.

On the other hand, when executing an earthquake scenario, as shown in FIG. 11 , epicenter coordinates are selected from the map, and the degree of damage caused by an earthquake can be simulated by adjusting the epicenter depth and earthquake scale. The epicenter coordinates can be adjusted by clicking the desired location by enlarging the map area, and the epicenter depth can be entered arbitrarily by the user, and the magnitude of the earthquake can be increased or decreased by 0.5 units. The degree of earthquake damage of a facility can be predicted through the simulation as described above.

In addition to this, a water quality scenario can be executed. As shown in FIG. 12 , a change in the flow rate is predicted by adjusting the supply and demand, and the water quality damage range according to the change in the flow rate can be simulated. In the case of supply, the decrease can be adjusted in 5% increments, and in the case of demand, the increase can be adjusted in 5% increments. Through the simulation as described above, it is possible to predict the degree of damage to the water quality of the facility.

The history of performing the above scenarios can be checked again through the pipe network analysis history menu. Through the above menu, it is possible to search by condition of water supply area, disaster type, scenario name, and creation date and time.

When a history is selected through the search as described above, it is possible to check the age of the pipeline, the risk distribution rate by age, and the analysis results of individual pipelines.

In the case of the diagnostic evaluation menu, it consists of sub-menus of risk evaluation and risk evaluation history.

For the above risk assessment, a water supply area must first be selected. When you select a water supply, a list of pipelines for that area is loaded and you can select a scenario for each disaster.

As shown in Fig. 13, when each disaster scenario is selected, the risk score for each pipeline of each scenario is loaded, and when all three scenarios are selected, the analysis execution button is activated.

When the above analysis is performed, the grade and overall risk value according to the risk score for each disaster are determined. The analysis screen as described above is shown in FIG. 14 .

The history of risk evaluation as described above can also be checked collectively through the risk evaluation history menu. Through the above menu, you can check the risk assessment level for each pipeline and the urgency of maintenance.

On the other hand, the content of the risk assessment can be derived in connection with the data obtained through the asset management integrated system of the upper and lower pipelines as described above.

Specifically, the diagnosis and evaluation of the upper and lower pipelines provided in the upper and lower pipeline safety management system menu is a data management system that stores CCTV investigation and visual inspection data through self-propelled exploration of the upper and lower pipelines and performs defect coding; It may be calculated through a risk assessment system that performs risk analysis and evaluates risk priorities by using information from the data management system.

Through the simulation of the current state of the water supply pipeline and the disaster situation as described above, it is possible to set the priority of maintenance in consideration of the current state as well as the future risk.
