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

The present invention diagnoses the stability of facilities through operation support and precise diagnosis of facilities based on sewage pipe and sewage manhole information among underground facilities. After evaluation, the annual cost is calculated through LCC (Life Cycle Cost) and LOS (Level of Service) simulation results for each facility. It is about a sewage pipe safety management system using a web application that provides reference materials for budget planning.

Currently, domestic underground facilities are growing quantitatively and qualitatively, but asset management is not widely applied despite the fact that underground facilities are social infrastructures due to the absence of specialized companies in water management and lack of expertise at the level of domestic privatization. Service level introduction to set maintenance targets 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, research on the introduction of an asset management system for social infrastructure is being actively conducted in Korea. Or, it is essential to apply an asset management technique that converts to a preventive maintenance system because it has characteristics that are much greater than maintenance costs.

In the case of sewage pipes, it is important to properly manage them because they are directly connected to the disaster prevention of urban floods that have recently occurred frequently in the event of an accident. The deterioration of the sewage pipe network is progressing, centering on large cities where the introduction of modern sewerage was initially performed, deteriorating the function of the overall sewage system. However, unlike other general public facilities, the sewer network is buried underground, which makes it very difficult to operate and maintain. many.

Accordingly, it is necessary to expand its application to the decision-making system for rational decision-making of maintenance and repair plans. Maintenance and improvement of the sewer pipe network requires a huge amount of budget and time, and some decision-making techniques for maintenance and improvement of the sewer system are proposed, but the connection with the systematically established asset management system is unclear and the utilization is low.

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

On the other hand, the overall details of the sewage pipe safety management system, a data management system that stores CCTV investigation and visual inspection data through self-propelled sewage vehicle exploration and performs defect coding, and a risk analysis using the information of the data management system a risk evaluation system that analyzes service levels and sets service goals; a maintenance cost prediction system that predicts the size of maintenance costs by analyzing life cycles and replacement costs; Sewerage pipelines including a comprehensive maintenance priority evaluation system that evaluates overall maintenance priorities based on the results derived from the risk evaluation system, service evaluation system, and maintenance cost prediction system, and an asset management system that establishes sewage maintenance and budget plans. It is desirable to derive based on the integrated asset management system.

The contents of the integrated sewage pipe asset management system are as described in FIG. 7 .

Specifically, the data management system may receive CCTV image information of the sewage pipe using a self-propelled vehicle and information through visual inspection to perform defect coding on the sewer pipe to calculate a defect code, defect grade, defect score, and condition grade.

The defect code is determined according to a defect item, and the defect item collectively refers to internal and external defects found during facility inspection. Deformation of sedimentary soil and pipe diameter, leakage of pipe joints, steps at joints, gaps, damage, etc. may be included.

The defect grade is classified into a total of three grades for classification according to the size of the defect item, and the grades are represented by A, B, and C, with A being a serious defect, B being a normal defect, and C being a slight defect. is evaluated as

On the other hand, all data such as information or defect information input through investigation in the data management system can be input and output, large-capacity data can be managed, and a function to create a report on the results of the investigation is provided. Also, search information list search and detailed search are supported. The investigation result report may include basic information and contents of investigation results.

In addition, the data management system can be linked with GIS (Geographical Information System) to receive information supported by GIS, such as pipe type, location, depth, and year of burial.

On the other hand, the risk evaluation system evaluates the overall risk priority by utilizing structural risk evaluation results, mathematical risk evaluation results, and weight coefficient data.

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

The risk evaluation system calculates defect scores and risk ratings for each division through defect scores and weight coefficient data according to structural and hydraulic evaluations. The risk grade calculates the degree of defect on a scale of 1 to 5. Based on the contents calculated in this way, comprehensive risk priorities are evaluated and a list is provided.

That is, the risk evaluation system imports and calculates environmental importance data from the GIS sewage pipe attribute table, and determines risk priority by calculating risk scores (structural re-average score + mathematical average score) in consideration of the weight coefficient data for each conduit. and the results are output as risk scores and risk ratings. In addition, risk priorities are expressed in the form of a chart.

The structural and mathematical analysis results and prioritization results are stored in the system, evaluation results can be expressed based on GIS, and the results can be downloaded to Excel.

On the other hand, the data management system and risk management system, in the first step of obtaining defect information by analyzing information obtained through exploration by putting a self-propelled vehicle inside the water pipe, using artificial intelligence for defect and risk analysis, the defect The second step of obtaining risk information by analyzing information, the third step of modeling the sewage pipe in 3D using the defect information and risk information, and the fourth step of continuously outputting the results of the modeling through the screen. It is desirable to proceed to do so.

In addition, steps 1 to 4 may all be performed through an information analysis program. In the process of extracting, cutting, and joining the image information obtained through the self-propelled vehicle in the first step, the information analysis program can increase the accuracy of the defect information by applying a distortion correction technique.

In addition, in the second step, location information may be displayed through a travel distance measurement system based on the travel distance and travel time of the self-propelled vehicle measured using the gear and communication cable of the self-propelled vehicle, and the third step In , a three-dimensional drawing can be formed using the travel distance of the self-propelled vehicle obtained from the previous travel distance measuring system as the length of the pipeline.

In addition, in the fourth step, it is possible to enlarge, reduce, and rotate the location of the defective part of the modeled product, and it may have a function of enabling output speed control.

More specifically, in the present invention, in step 1, defect location information can be confirmed through a movement distance measuring system.

The system indicates the moving distance of the self-propelled vehicle after a specific time after the self-propelled vehicle exploration starts, and can obtain location information using this, and the injection amount of the communication cable based on the number of rotations of the communication cable connected to the self-propelled vehicle and the gear connected. Calculate the moving distance of the self-propelled vehicle. Here, the communication cable is sufficiently hard and thick to measure the distance since it does not stretch or bend in the middle.

On the other hand, when a self-propelled vehicle starts exploration, an image is taken through a camera and the travel time is measured, and when the image is stored in an information analysis program, the travel time is also saved, so the travel time when a specific image is captured can be known. there is.

Therefore, by using the travel time measurement system that can know the travel time information stored in the image and the distance according to the travel time, the travel distance of the self-propelled vehicle when the image is captured can be known, and through this, the location where the image was captured can know

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

On the other hand, as described above, an 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, more rapid and accurate defect and risk analysis is possible through an information analysis program using artificial intelligence.

The information analysis program using artificial intelligence proceeds with the development drawing of the pipeline from the videos and images taken from the start point to the end point of the pipeline to enlarge and confirm the defect information and defects, and 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 defects in the pipeline. In addition, the comprehensive risk score and risk grade can be known through quantitative analysis per unit of pipeline, which can be an important indicator in determining maintenance, repair, and replacement. In other words, it is useful for asset management and safety management because it is possible to know the exact location of the defect as well as the severity of the defect and the corresponding risk by analyzing the defect information and risk information of the defect from the pipeline development drawing.

On the other hand, in the three-step process, in the present invention, a three-dimensional conduit shape can be obtained.

In order to obtain a 3D shape, the X-axis and Y-axis direction information of the distance information of the development drawing is extracted, and the Z-axis is reconstructed in 3D by connecting a straight line from the center point of the view at the exploration start point to the ground where the facility is buried. A coordinate space composed of ,Y,Z axes can be set.

The coordinate space sets the midpoint (0,0,0) where the X, Y, and Z axes are orthogonal to the exploration start point, and connects points that exist along the length corresponding to the radius of the pipe on the YZ plane from the midpoint to determine the pipe diameter. can create At this time, the midpoint becomes the center point of the pipe diameter, and the length of the pipe diameter cannot be a negative value because it is the diameter of the pipe.

The travel distance of the self-propelled vehicle can be known from the travel distance measuring 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 on the X axis, and the coordinates entered on the X axis are entered again. A pipe diameter is created by setting coordinates by the radius of the pipe once in the positive and negative directions of the Y and Z axes. Finally, a cylindrical three-dimensional drawing is formed by connecting the pipe diameters of the starting point and the ending point, and when the two-dimensional development drawing of the present invention is covered on the cylindrical drawing, it can be reconstructed into a three-dimensional conduit.

In addition, the modeling is performed by matching location information, defect information, and risk information corresponding to each defect included in the pipeline.

For example, when there is a leak in a pipe, the location, grade, score of the defect and the structural and hydraulic risk score of the conduit where the defect exists, the overall risk score, and what environmental importance are included in the defect. All information about the defect is modeled by being matched with the corresponding defect.

Accordingly, the user can click the defect in the 3-dimensionally modeled conduit with a cursor through the input/output device. When a defect in the pipeline is selected, information corresponding to the selected defect is output.

In step 4, the pipeline modeled in 3D 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.

Meanwhile, the service evaluation system performs a function of setting a reasonable goal in both directions through gap analysis between a service level from a customer's point of view and a service level from a manager's point of view. Here, the service level is a level that can be presented by a supplier at the current technical and budgetary level. Performance indicators classified according to environmental, economic, social and cultural standards are classified, and each category is scored (1 to 5 points). is scored The service target refers to a realistic and feasible target level presented in the future by considering a service level required by a user based on a current service level.

The service evaluation system integrates service level objectives from the customer's point of view and service level objectives from the organization's point of view, and performs LOS (Level Of Service) evaluation to select a reasonable target level through gap analysis of the service level objectives. .

At this time, the service level from the manager's point of view is classified into grades by engineering digitization of service scales by district and subunit, and the service level from the customer's point of view is classified into grades by engineering digitizing the service level experienced by customers. As described above, the difference (gap) of the results calculated by numbers and grades is analyzed, and the target level is adjusted according to the importance and population density of each facility.

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

The satisfaction level can be calculated by digitizing the service level calculated from the importance of facilities according to the population density by 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 weight coefficients in the risk evaluation system, and accordingly, a risk score may be calculated and reflected in risk priority.

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

On the other hand, the maintenance cost prediction system performs a probabilistic LCC (Life Cycle Cost) analysis considering the uncertainty of basic data, and predicts the size of the maintenance cost required for each item of the sewage pipe. The basic data includes basic data of an analysis target, location information, traffic information, maintenance information, and discount rate information, and the traffic information and maintenance information can be provided from GIS information.

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

In addition, the maintenance cost prediction system calculates the initial investment cost, maintenance cost and disassembly and disposal cost through LCC analysis. 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 in order to perform the LCC analysis. The maintenance information of the analysis target is provided from the database. The maintenance information includes repair, reinforcement, and replacement characteristic values and maintenance scenarios of the facility.

Meanwhile, in the present invention, it is preferable to select a stochastic LCC analysis method considering uncertainty of basic data. The stochastic analysis method is an analysis method that sets a stochastic characteristic value following a certain distribution rather than a specific value for the basic data of LCC analysis, and presents the analysis result as a probability characteristic value by conducting a computer simulation based on this. Therefore, it is a methodology that is more advanced than the definitive analysis method.

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

Meanwhile, the comprehensive maintenance priority evaluation system establishes the most optimized maintenance priority by integrating risk priorities and maintenance costs calculated to establish a maintenance priority strategy. Specifically, the risk priority calculated as the product of the sewer severity score reflecting the structural and hydraulic defect score and the environmental importance (weight coefficient) reflecting the target service level derived from the customer and manager survey analysis and the LCC analysis derived By reflecting the life cycle cost and maintenance cost, practical sewage pipe maintenance priorities 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 is based on the difference in the gap between the planned service and service satisfaction between the supplier and the user, so that the future service level can be judged. The risk assessment is a criterion for determining the actual level of deterioration by identifying the actual state and defect level of the current facility. Establish optimal maintenance priorities by comprehensively determining all three items above.

As a result, it is possible to present the priority of comprehensive maintenance of sewage pipes in the categories of dredging, partial repair, total repair, and replacement to the system user, which makes it possible to establish an easy and efficient annual maintenance plan.

In addition, when exceptional emergency repair costs due to an unexpected accident are exhausted, maintenance priorities are rearranged, and the remaining budget and repairable range can be indicated accordingly. This can support mid- to long-term maintenance plan establishment and efficient budget execution.

On the other hand, it is possible to implement the contents of the sewage pipe asset management integrated system as described above on the website through the sewer pipe safety management system menu.

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

As described in FIG. 8 , the sewage pipe safety management system menu may include submenus such as survey, prediction menu, diagnosis, evaluation menu, budget planning menu, general management menu, asset management menu, property management menu, and the like.

Specifically, as shown in FIG. 9, when selecting the rainfall frequency and rainfall distribution on the scenario selection screen and then selecting the view of the sewage pipe network, as shown in FIG. You can check the pipeline.

In addition, when selecting the flood prediction map view, as shown in FIG. 11, it is possible to check how the water depth in the surrounding area changes when water overflows from the sewer pipe and flows to the surface, and as shown in FIGS. 12 and 13, detailed information of the pipe or manhole can also be checked directly.

On the other hand, the diagnosis and evaluation menu may have a detailed diagnosis menu and a list evaluation menu as sub-menus, and the contents of the diagnosis and evaluation may be derived through the integrated sewage pipe asset management system as described above.

Specifically, the diagnosis and evaluation of the sewage pipe provided by the sewage pipe safety management system menu is a data management system that stores CCTV investigation and visual inspection data through autonomous vehicle exploration of the sewer pipe and performs defect coding, and information of the data management system. It can be calculated through a risk assessment system that uses risk analysis to evaluate risk priorities.

In the detailed diagnosis menu, you can check the reading result for the registered sewage pipe.

Through the detailed diagnosis business list, it is possible to search by business year, business name, survey method, period, etc. of the survey, and selecting the GIS column of the searched data displays the relevant business area on the map. When the searched data is selected, it moves to the result search screen, and when the registration button is selected, it moves to the reading list of the corresponding business.

When searching for results, the number of defects for each pipeline of the selected inspection project is displayed, and when a pipeline is selected, it moves to the defect reading result screen.

As shown in FIG. 14, on the defect reading result screen, selected pipe information and registered defect information can be inquired, and when the analysis information registration button is selected, it is possible to move to the defect information registration and correction page.

On the other hand, as described above, in the present invention, since it is possible to output a drawing of a 3D shape, it is possible to utilize functions of enlarging, reducing, and moving a pipe drawing.
