Description

Technology Field

[0001] The present invention relates to a BIM quality review issue management module for quality management of railway infrastructure BIM data, and more specifically, to a BIM quality review issue management module for quality management of railway infrastructure BIM data capable of providing quality review results and issues of railway infrastructure BIM data to an integrated railway infrastructure operation system. Background Technology

[0002] Building Information Modeling (BIM) refers to the process of virtually modeling a facility in a multidimensional virtual space, encompassing planning, design, engineering (structure, facilities, electrical, etc.), construction, and even maintenance and disposal.

[0003] This BIM method is a 3D-based design and modeling method that digitizes buildings to create numerical data and enables 3D display effects. It generates length data connecting the start and end points of lines rather than simple line and surface work, and for surfaces, the area is digitized based on closed surfaces. When the length and area data are combined, volume data can be obtained.

[0004] Furthermore, the BIM method includes information regarding the shape, attribute, relationships, and topology of objects, offering excellent analysis, service integration, and usability. In other words, BIM allows building objects such as walls, slabs, windows, doors, roofs, and stairs to express their respective attributes, enabling the recognition of their interrelationships and the immediate reflection of building changes in the design. Therefore, by utilizing BIM, it is possible to integrate and manage information across all stages through project-specific and process-specific compatibility and sharing of data generated during construction, regardless of whether the building being designed is structured or irregular.

[0005] Recently, there has been an increasing trend of attempts to apply this BIM technology not only to the construction industry but also to railway infrastructure projects. However, there is a limitation in that the quality review of BIM data across the entire construction industry, including railway infrastructure, is currently performed primarily through visual and physical quality reviews using general commercial software, as shown in Fig. 1.

[0006] As a prior art document related to BIM data quality review, Korean Registered Patent Publication No. 10-2586663 (Title of Invention: Structure of Civil Engineering BIM Data Quality Check Platform) has been disclosed.

[0007] As illustrated in Fig. 2, the aforementioned prior art provides a basic UI for a Civil BIM Code Checker (CBC) to review the quality of civil engineering BIM data through the operation of an automated program, and can manage and exchange information models such as Civil BIM models, roads, alignments, profiles, and cross-sections modeled in various BIM modeler software. Furthermore, the aforementioned prior art relates to a rule-based BIM data quality review platform structure that reviews the quality of civil engineering BIM data using an automated program after rules are established through rules. However, this prior art has a limitation in that it is restricted to a single stand-alone system.

[0008] Meanwhile, the railway infrastructure integrated operation system is a Common Data Environment (CDE), a cloud-based space where construction project information is stored and project participants can access it, as shown in Fig. 3. It operates as a collaboration platform between the client and the contractor for a series of procedures such as creation, work, sharing, review, action, supplementation, approval, delivery, and transfer of BIM data. However, as shown in Fig. 4 (a), the BIM model can be visually checked using an Industry Foundation Classes (IFC) viewer, so it does not include a quality review function.

[0009] The rule-based BIM data quality review SW shown in Fig. 1 and the railway infrastructure integrated operation system shown in Fig. 3 are operated separately as shown in Fig. 5. The rule-based BIM data quality review SW can download BIM data from the railway infrastructure integrated operation system to perform a quality review, and the railway infrastructure integrated operation system can check the results of the quality review from the BIM data quality review SW in the form of a document such as PDF, as shown in Fig. 4 (b).

[0010] As such, since the integrated railway infrastructure operation system allows verification of quality review results only in document form, there is a risk of human error during information exchange between quality review issues and collaboration systems, and because data consistency cannot be guaranteed during decision-making, there are disadvantages in terms of BIM productivity.

[0011] To improve these disadvantages of BIM productivity, we intend to develop a module that can manage quality review result issues by parsing the quality review results (output) performed in rule-based BIM data quality review software and inputting the quality review results into the railway infrastructure integrated operation system.

[0014] In addition, the second objective of the present invention is to provide a BIM quality review issue management module for quality management of railway infrastructure BIM data that can improve rapid decision-making and the consistency of BIM data by identifying quality review results and issues of railway infrastructure BIM data in a cloud environment and taking action.

Effects of the invention

[0017] The present invention can automatically provide quality review results and issues of railway infrastructure BIM data to the SW of the railway infrastructure integrated operation system without data loss.

[0018] In addition, the present invention can rapidly and accurately support a series of decision-making processes, such as creation, work, sharing, review, action, approval, delivery, and transfer of railway infrastructure BIM data, by identifying quality review results and issues of railway infrastructure BIM data in a cloud environment and taking action, thereby improving the consistency of BIM data.

[0019] Furthermore, since the BIM quality review issue management module of the present invention can be downloaded from the railway infrastructure integrated operation system, installation and use are easy and convenient without a separate purchase procedure, and users of the railway infrastructure integrated operation system can enhance the effectiveness of collaboration by sharing information related to the quality management of railway infrastructure BIM data through the user interface (UI) of the railway infrastructure integrated operation system.

[0029] Composition of the embodiment

[0030] Below, the BIM quality review issue management module (100) of the present invention will be described in detail.

[0031] The BIM quality review issue management module (100) of the present invention may be implemented and executed as a program that is additionally installed (downloaded) in the form of an add-in to the SW (software) of the railway infrastructure integrated operation system (10), or may be executed on a cloud basis.

[0032] In this specification, a program-based BIM quality review issue management module (100) that can be additionally installed as an add-in will be described as one embodiment, and a cloud-based BIM quality review issue management module (100) will be described as another embodiment.

[0033] In the present invention, a BIM quality review issue management module (100) of one embodiment provides the results of a quality review of railway infrastructure BIM data and issues to a railway infrastructure integrated operation system (10), and the components for this are as follows.

[0034] FIG. 6 is a drawing for explaining a BIM quality review issue management module according to an embodiment of the present invention.

[0035] Referring to FIG. 6, a BIM quality review issue management module (100) of one embodiment includes a communication unit (101), an input unit (102), a conversion unit (103), and an output unit (104).

[0036] The communication unit (101) can be executed on a cloud basis when the BIM quality review issue management module (100) is downloaded as an add-in from the railway infrastructure integrated operation system (10).

[0037] The input unit (102) can import quality review issue data regarding the quality review results and issues of railway infrastructure BIM data output from a quality control checker (20) capable of communicating through the communication unit (101), and upload the quality review issue data to the conversion unit (103).

[0038] At this time, the quality review issue data that the input unit (102) retrieves may be in the format of unprocessed raw data.

[0039] In addition, the format of the quality review issue data may be xml, xls, pdf, etc., but is not limited thereto, and depending on the design and configuration changes of the quality control checker (20), it may be formed in other formats (e.g., JSON, YAML) excluding the aforementioned formats.

[0040] The conversion unit (103) can sequentially perform parsing and querying processes on the quality review issue data retrieved by the input unit (102) to sort the quality review issue data into a form required by the user (or administrator) of the railway infrastructure integrated operation system (10).

[0041] In the present invention, the parsing process of the conversion unit (103) refers to the process of analyzing data configured in a specific format and understanding its meaning in computer science and programming.

[0042] More specifically, the parsing process of the conversion unit (103) may include at least one of the following processes: a string parsing process that extracts specific data from a string or converts it into a desired format; a language parsing process that analyzes source code of a programming language or markup language, checks for syntax errors, and converts it into executable code; an HTML and XML parsing process that analyzes HTML or XML documents of a webpage to allow a web browser to render the documents or a web scraping tool to extract data from the website; a parsing process that analyzes text documents in natural language processing to understand sentence structure, vocabulary, grammar, semantics, etc.; and a data format parsing process that analyzes specific data formats (e.g., XML, JSON, YAML) to extract and process data.

[0043] In the present invention, the query process of the conversion unit (103) refers to a request from a client to show specific data to the database. At this time, the database is an input unit (102) that retrieves quality review issue data, and the specific data is quality review issue data that has undergone a parsing process to enable conversion into a BCF (BIM Collaboration Format) file format in the output unit (104) to be described later, and the client refers to a user (or administrator) of the railway infrastructure integrated operation system (10).

[0044] The output unit (104) can convert the quality review issue data provided by the conversion unit (103) into a BCF file format so that the quality review issue data can be utilized in the railway infrastructure integrated operation system (10).

[0045] In the present invention, a BCF file refers to an open BIM file format for railway infrastructure BIM collaboration in various ways, such as issue management of railway infrastructure BIM, and may include physical quality review information, logical quality review information, and data attribute quality review information of railway infrastructure BIM data.

[0046] In this context, physical quality review, logical quality review, and data attribute quality review serve as standards for BIM data quality review. Physical quality review examines quality based on physical requirements, such as the physical shape of BIM data and collisions or separation between objects; logical quality review examines quality based on logical requirements, such as relevant laws or design standards; and data attribute quality review examines quality based on attribute requirements of BIM data, such as object classification systems or design information.

[0047] Therefore, physical quality review information, logical quality review information, and data attribute quality review information refer to the generalized morphological characteristics of information for reviewing the quality of BIM data.

[0048] In the present invention, the railway infrastructure integrated operation system (10) can provide the user with quality review issue data converted into a BCF file format at the output unit (104).

[0049] Figure 7 is a diagram illustrating the state of checking quality review result issues through the IFC viewer in the railway infrastructure integrated operation system of the present invention.

[0050] Referring to FIG. 7, the railway infrastructure integrated operation system (10) can display quality review issue data converted into a BCF file format at the output unit (104) through its own ICF viewer function and provide it to the user.

[0051] In the present invention, the IFC viewer of the railway infrastructure integrated operation system (10) refers to a viewer program for displaying a file with the file name extension IFC.

[0052] That is, when the railway infrastructure integrated operation system (10) of the present invention displays quality review issue data through the IFC viewer function, it is preferable to convert the format of the quality review issue data to IFC and then display the quality review issue data.

[0053] At this time, the quality review issue data displayed by the IFC viewer of the railway infrastructure integrated operation system (10) may include a 3D railway system model and a 4D linear simulation generated by the 3D model generation unit (112) to be described later, as shown in FIG. 7.

[0054] In addition, the quality review issue data displayed by the IFC viewer of the integrated railway infrastructure operation system (10) may include raw data and issue matters of attribute information such as the classification system and design information of the railway system applied during quality review using the IFC viewer.

[0055] Figure 8 is a diagram illustrating the state of checking quality review result issues through a document viewer in the railway infrastructure integrated operation system of the present invention.

[0056] Referring to FIG. 8, the railway infrastructure integrated operation system (10) can display and provide to the user a quality review result issue report generated based on quality review issue data converted into a BCF file format at the output unit (104) through its own document viewer function.

[0057] In the present invention, the quality review result issue report displayed by the document viewer of the railway infrastructure integrated operation system (10) may be a report intended to provide information to the user regarding risk factors at the railway construction site and the railway completion site, as illustrated in FIG. 8, and the report may include a detailed statement of construction for building railway infrastructure that includes the name of the construction work, specifications, quantity and unit, material costs, labor costs, expenses, etc.

[0058] Figure 9 is a diagram illustrating the state of checking quality review result issues through a dashboard in the railway infrastructure integrated operation system of the present invention.

[0059] Referring to FIG. 9, the railway infrastructure integrated operation system (10) can provide to the user, through its own dashboard function, the analysis type and pattern of the quality review results analyzed using quality review issue data converted into a BCF file format at the output unit (104) by displaying them in a chart or graphic.

[0060] In the present invention, the type and pattern displayed by the dashboard of the railway infrastructure integrated operation system (10) refers to the graph form and information of the quality review result analysis as shown in FIG. 9, and more specifically, may include a circle type, a histogram, a bar chart, a scatter plot, etc.

[0061] In addition, by visualizing the results of quality reviews through the railway infrastructure integrated operation system (10)'s own dashboard function, users can quickly and accurately identify the type of quality issue and take quick action to correct and supplement the quality issue.

[0062] In addition, the quality review issue data displayed on the dashboard may include the results of interference reviews of the railway system, design criteria reviews, data attribute information reviews, drawing reviews, and quantity reviews, bill of materials reviews, and report reviews of quality review issue reports.

[0063] Meanwhile, the railway infrastructure integrated operation system (10) of the present invention is a system for managing the life cycle of railway infrastructure by incorporating BIM technology into railway infrastructure projects, and the process of the railway infrastructure project is as follows.

[0064] Figure 10 is a flowchart illustrating the process of a railway infrastructure project.

[0065] Referring to Fig. 10, the railway infrastructure project (S10) can proceed in the order of the planning stage (S1), ordering stage (S2), design stage (S3), construction stage (S4), completion stage (S5), and operation and maintenance stage (S6).

[0066] Here, the planning stage (S1) is the process of establishing a plan for a railway infrastructure project; the ordering stage (S2) is the process of placing orders with suppliers to receive products or materials necessary for the completion of the railway infrastructure; the design stage (S3) is the process of designing a railway system; the construction stage (S4) is the process of starting and finishing the construction of the railway system; the completion stage (S5) is the process of handling construction and administrative issues of the railway system; and the operation and maintenance stage (S6) is the process of operating and maintaining the railway system.

[0067] In addition, the railway system in the present invention may include, but is not limited to, a set of components for implementing railway infrastructure, such as tracks, electrical facilities, signaling facilities, and communication facilities, and may include additional components necessary for railway infrastructure. However, below, the railway system components will be described as being multiple, including tracks, electrical facilities, signaling facilities, and communication facilities.

[0068] Meanwhile, the railway infrastructure integrated operation system (10) of the present invention aims to build a standardized integrated operation system that is linked to the operation and maintenance stage (S6) by advancing BIM-based design stage (S3), construction stage (S4), and completion stage (S5) technologies to manage the life cycle of the railway system based on BIM (Building Information Modeling) technology.

[0069] That is, the railway infrastructure integrated operation system (10) aims to manage the life cycle of the railway system through a BIM-based design phase (S3), construction phase (S4), completion phase (S5), and operation and maintenance phase (S6), and the components for this are as shown in FIG. 11.

[0070] FIG. 11 is a block diagram schematically illustrating the configuration of the railway infrastructure integrated operation system of the present invention.

[0071] Referring to FIG. 11, the railway infrastructure integrated operation system (10) of the present invention may be equipped with a linear 4D simulation unit (11), a safety diagnosis unit (12), a construction and completion management unit (13), a maintenance management unit (14), a database server (15), a communication unit (16), and a control unit (17). However, the components of the railway infrastructure integrated operation system (10) are not limited, and components may be added or omitted by design modifications made by the user.

[0072] The linear 4D simulation unit (11) executes a linear 4D simulation to design the tracks, electrical facilities, signal facilities and communication facilities, which are components for implementing a railway system based on BIM modeling, and the means to be provided for executing the linear 4D simulation are as follows.

[0073] FIG. 12 is a block diagram schematically illustrating the detailed configuration of the linear 4D simulation unit illustrated in FIG. 11, and FIG. 13 is a conceptual diagram schematically illustrating the operation of the linear 4D simulation unit illustrated in FIG. 11.

[0074] Referring to FIGS. 12 and 13, the linear 4D simulation unit (11) may be equipped with a first information input unit (111), a 3D model generation unit (112), a second information input unit (113), a linear 4D model conversion unit (114), and a design BIM information management unit (115). However, the components of the linear 4D simulation unit (11) are not limited, and components may be added or omitted by design modifications made by the user.

[0075] Here, the operation of the linear 4D simulation unit (11) can be executed through a user's terminal (e.g., PC, smartphone, tablet, etc.) that can be remotely controlled through linkage with the linear 4D simulation unit (11) or through an interface provided on the user's terminal.

[0076] In addition, the interface of the user terminal is a concept that includes a hardware device and a software program for providing an environment to interact with the linear 4D simulation unit (11) and receiving commands from a user of the railway infrastructure integrated operation system (10) and converting them into electronic data, and may include, for example, input devices such as a keyboard, mouse, and touch pen, and output devices such as a display.

[0077] Furthermore, the operation of the linear 4D simulation unit (11) is not limited to being performed by a user, and may be automatically executed through deep learning or machine learning-based learning of an artificial intelligence model.

[0078] In the present invention, the first information input unit (111) includes a parametric model (111a) and a BIM library (111b), the parametric model (111a) sets parameters for each component of the railway system through input of parameters (dimensions) for each component of the railway system, and the BIM library (111b) sets the shape of each component of the railway system through input (or selection) of the shape of each component of the railway system, thereby enabling the construction of a BIM for each component of the railway system.

[0079] The 3D model generation unit (112) generates a 3D railway system model by 3D modeling a component of a railway system with parameters and shapes set in the first information input unit (111), and the process of generating the 3D railway system model is as follows.

[0080] First, the 3D model generation unit (112) can generate a 3D terrain model for the section of the railway alignment where the 3D railway system model will be generated.

[0081] After that, the 3D model generation unit (112) can generate the same number of nodes included in the 2D lines for the planar alignment and the longitudinal alignment of the railway alignment, and then extract the planar coordinates and vertical coordinates for each node to generate 3D coordinate data for the section of the railway alignment.

[0082] After that, the 3D model generation unit (112) can generate a 3D railway system model by reflecting 3D coordinate data into the 3D terrain model to set a section of the railway alignment, and by placing a railway system component with parameters and shape set through the first information input unit (111) in the section of the railway alignment.

[0083] At this time, if the 3D model generation unit (112) receives a plurality of railway system members from the first information input unit (111), merges (combines) them into one object, and then places them on a 3D terrain model that reflects 3D coordinate data.

[0084] The second information input unit (113) sets schedule information and location information related to the railway system components to be applied to the linear 4D simulation.

[0085] Here, the schedule information includes data on the construction schedule for each component of the railway system, and the location information includes data on the construction location for each component of the railway system where the schedule information is set, and the schedule information and location information can be displayed through the IFC viewer of the railway infrastructure integrated operation system (10).

[0086] The linear 4D model conversion unit (114) generates a linear 4D simulation using 3D modeling, schedule information, and location information. That is, it generates a linear 4D simulation by reflecting the schedule information and location information set in the second information input unit (113) into the 3D railway system model generated by the 3D model generation unit.

[0087] Here, the linear 4D simulation is a linear simulation because the track (railway), which is a linear structure, is included in the 3D railway system, and the linear 4D simulation is converted into a 4D simulation by reflecting schedule information and location information into the 3D railway system model.

[0088] The design BIM information management unit (115) executes the linear 4D simulation generated by the linear 4D model conversion unit (114) at least once, and then transmits the result of the linear 4D simulation to the database server (15) so that the result of the linear 4D simulation is reflected in the design BIM information stored in the database server (15).

[0089] Here, the result of the linear 4D simulation means whether the design of each railway system component in the linear 4D simulation is designed in accordance with schedule information and location information, and the user of the railway infrastructure integrated operation system (10) can review the construction location included in the location information while determining whether the railway system components are designed in the order of the construction schedule included in the schedule information through the linear 4D simulation.

[0090] Additionally, when the linear 4D simulation is executed at least once, the design BIM information management unit (115) generates first image data for the linear 4D simulation in which the design of each railway system member proceeds in the order of schedule information, and extracts second image data for the event (process) from the start to the end of the design of each railway system member from the first image data.

[0091] In this way, separately generating and extracting first image data and second image data for linear 4D simulation is intended to allow the user to review a 3D railway system model including the component design process of the railway system through linear 4D simulation using the first image data, and to closely review the process from the start to the end of the design of each railway system using the second image data.

[0092] Meanwhile, as the design BIM information management department (115) generates the first and second image data, it is desirable that the design BIM information additionally reflects the first and second image data of the linear 4D simulation as well as the results of the linear 4D simulation.

[0093] The safety diagnosis unit (12) receives construction BIM information containing data on the construction procedure of the railway system from the database server (15), converts the construction BIM information into VR or AR content to diagnose the safety status of the railway construction site, and provides progress information of the railway construction site through the diagnosis of the safety status of the railway construction site.

[0094] That is, the safety diagnosis unit (12) has the characteristic of expressing the safety status of the railway construction site based on VR or AR, and can be implemented as a means (e.g., AR-based site vision) that can be applied to devices or facilities for the construction of the railway system at the railway construction site.

[0095] The construction and completion management department (13) manages the railway construction site and the railway completion site using construction BIM information and completion BIM information generated by inspecting (reverse engineering) the railway system at the railway construction site and the railway completion site based on drone control and LiDAR installed on the drone.

[0096] Since the drone control used by the construction and completion management department (13) and the lidar installed on the drone are common, a detailed explanation of them will be omitted for convenience.

[0097] The maintenance department (14) maintains the railway system by checking for damage or malfunction of components of the railway system based on integrated BIM information received from the database server (150).

[0098] The database server (150) stores integrated BIM information including BIM information for the stages of the railway infrastructure project, such as the planning stage (S1), ordering stage (S2), design stage (S3), construction stage (S4), completion stage (S5), and operation and maintenance stage (S6).

[0099] That is, the integrated BIM information stored in the database server (150) is preferably understood as storing BIM information for each stage of the railway infrastructure project, such as planning, ordering, design, construction, completion, operation, and maintenance.

[0100] The communication unit (16) is equipped with a communication means to allow a user to access the railway infrastructure integrated operation system (10).

[0101] Here, the term "user" may be at least one of the employees of the ordering agency, design firm, construction firm, supervisory firm, or related organization that can use the railway infrastructure integrated operation system (10).

[0102] In the present invention, the quality control checker (20) is a quality check platform for reviewing the quality of railway infrastructure BIM data, and can be operated separately from the railway infrastructure integrated operation system (10).
