Hereinafter, a method of inputting and retrieving damage information of a facility using a 3D spatial model according to the present invention will be described in detail with reference to the accompanying drawings.

In FIG. 2, a computer system, a CAD program for 2D and 3D work, and the like are included to implement a method for inputting and retrieving damage information of a facility using a 3D spatial model of the present invention. According to the present invention, a control module 10 converts a drawing created in a 2D or 3D format into a spatial model, inputs or outputs damage-related information into the converted spatial model, or converts and links a spatial model into a detailed model and a detailed model (10). ) Is included.

Furthermore, a 2D / 3D drawing creation module 20, which includes software such as CAD for drawing drawings in 2D and 3D formats, and a 2D / 3D drawing storage module 12 for storing drawings worked on the 2D / 3D drawing creation module. ), An input module 11 including a keyboard, a mouse, a camera, a camcorder, a voice recorder, a microphone, and the like for operation required for the work of a spatial model, and a unit member and a detailed member of a corresponding facility, including drawings in 2D or 3D format. A conversion module 13 for converting a spatial model into a space model, a storage module 14 for storing a spatial model such as facilities, units, and detailed members converted by the conversion module, and the control module 10. The damage information corresponding to each damage type and damage grade can be visually represented on the output module 15 including a monitor or a printer for displaying in a visual form by control, and the corresponding unit member and detail member where the damage has occurred. Apply to make A sticker module 16 including a plurality of stickers, damage history information DB 17 having stored therein information such as voice, photo, video or comment including damage stickers of corresponding unit members and detailed members; Simplification module 18 is included to simplify so that only the border image of the unit member of the facility is represented. Further, more various means, devices, systems or software will be included to implement a method for inputting and retrieving damage information of a facility using the three-dimensional spatial model of the present invention.

Figure 3 shows the overall flow of implementing the method of the present invention, by converting a 2D format drawing or a 3D format drawing of a facility requiring maintenance by the control module to a three-dimensional spatial model, refinement and input model It is possible to input information, inquire, and record DB according to the type of damage of the corresponding detail member. That is, as a preliminary operation for inputting and retrieving damage information of the facilities of the present invention, performing a basic operation of creating a 2D format or a 3D format drawing by using a CAD program or inquiring a previously created drawing (S10); , Steps S100 to S300 for 3D modeling are performed. And step (S400 ~ S800) corresponds to the process of entering the damage information of the facility. Step S20 includes storing the information performed through steps S400 to S800 in the database DB.

In FIG. 4, as a preliminary work of the facility, the control module 10 loads the unit member file created in the drawing of the 2D format in the normal CAD program and the like and models the drawing in the 3D format (S101). The modeled 3D file is converted into a vector file through the conversion module 13 (S102). In this case, this step may be omitted if the CAD program is already created in a 3D format drawing.

This is an embodiment of the present invention, Figure 8 is a captured image of the monitor screen diagrammatically showing the entire structural system model, Figure 9 is a reinforcement girder as a detailed model of the bridge, Figure 10 converts the reinforcement girder to * .dwg file format It shows the process. Here, although the bridge is exemplarily described among the facilities, the present invention is not limited thereto, and the input and retrieval method of damage information of the facilities required for the maintenance with respect to other facilities may also lead to the same process and results. Bridge components can be roughly classified into minimum inspection units for each member such as pylons, reinforcement girders, cable elements and anchorages. Classification is performed in steps 1 to 4, and the names of each member are indicated by abbreviations based on a drawing made by a CAD program. For example, DECK PLATE is indicated by DP and I-RIB is indicated by IR.

Furthermore, in Fig. 32, the reinforcement girder as a unit member corresponding to the first stage is divided into detailed members of GDSeg01 to GDSeg65 in the second stage, and in the third stage, the DECK PLATE, BOTTOM PLATE, DECK U-RIB, BOTTOM U-RIB, LEFT OUTER PLATE, RIGHT OUTER PLATE, LEFT I-RIB, RIGHT I-RIB, BOTTOM I-RIB, DIAPHRAGM are divided into detailed members. Less than -RIB Three levels of detailed members, such as DUR01 ~ DUR36, are divided into four more detailed members. Therefore, the unit member of the facility is divided into subdivided subdivided members to a predetermined level.

In addition, in step S102 of FIG. 4, the detailed members of the bridge using the specific CAD program included in the 2D / 3D drawing creation module 20 based on the names of the members classified by the control module 10. Model When the 3D modeling is completed, the extension is exported to the 2D / 3D drawing storage module 12 in the * .dwg file format. In other words, the file is converted to a vector file. Most 3D modeling programs currently used in the fields of civil engineering and architecture are converted to * .dwg file format and can be exported.

5 is a flowchart illustrating a process of performing a step (S200) of refining a 3D model in detail. In the detailed process of FIG. 5, the file modeled in the step S100 by the control module 10 is imported (imported) from the 2D / 3D drawing storage module 12 (S201), and from the imported file. Select the unit face of the detail member of the facility (S202). The control module 10 designates the unit group name of the detail member (S203), and stores the designated group name in the storage module 14 (S204). The grouping repeats steps S202 to S204 for all sub-members, and when grouping is completed (S205), specifies a file format (S206), and stores the designated file format in the storage module 14 ( S207).

Furthermore, the process of FIG. 5 is performed as shown in FIGS. 11 to 15. In the configuration of the 3D input model, for example, a tree structure between objects is generated by using a group function of a 3D drawing program. 11 to 15 used a 3D format drawing program, which was redefined using a group function of a 3D format drawing program by importing a * .dwg format file in step S100. Here, if the group function of the drawing creation program in the 3D format is used, the model and the name of the model are automatically generated by interworking with each other without further classification work on the tree structure or the substructure of the model through the program provided by the present invention. It is for. Accordingly, FIG. 11 selects a function for grouping the entire structural system model, FIG. 12 designates a corresponding file for grouping, and FIG. 13 stores each detailed member model as a group function. The redefinition of the redefinition by using the group function is exported as a file with the extension of * .3ds format. After selecting the save in FIG. 14, the file name is designated in FIG. 15 and stored.

The reason for storing using the * .3ds file format is that the characteristic of the * .3ds file is surface modeling, and the damage information on the object surface is generated when the damage information is generated on the object by the program provided by the present invention. Paste a tag or sticker to indicate that the user is easy to enter and confirm. In fact, since the location of the damage information is displayed on the surface, the surface information of the object is required. Here, the * .3ds file format is an open file format and is compatible because it has been used for a relatively long time in many programs. In addition, when the program is developed using a 3D object having a complicated structure due to the small size of the file, there is an advantage in program driving of another 3D file format. Therefore, step (S200) is a process for making a space model that is compatible with the development software for the development of a maintenance program using the space model and required for development.

On the other hand, in step S300 a basic operation is performed on the input model. The input model consists of a simple model and a detailed model of the entire structural system. In the case of the entire structural system of a bridge, it is composed of many components and complex structural systems. Displaying the entire structural model on a computer monitor screen at once may cause a lot of load on hardware and software, and may cause problems such as time delay in searching for the model. Therefore, it is better to divide the entire structural system into simple models and detailed models.

The simplified model is a model that reduces the capacity of the actual data by omitting the detailed members of the internal parts except for the edge where the unit member can be seen in appearance, and is simplified in the simplified module 18 by the control of the control module 10. Is performed. The detailed model is a model that matches the real model with all the components. The entire structure consists of a simplified model with reduced data capacity. Thereafter, the detailed model designated as the unit group in step S200 is linked with the simple model. At this time, the position coordinates of the detailed model are also set. Therefore, when the work of connecting the detailed members for the entire structural system is completed, the 3D input model is constructed. If you save the structured model as a whole and open the saved file later, a single input model is created in which the simple model and the detailed model are connected. The simple model and detailed model are composed to reduce the graphic load and to allow the user to construct the model by selecting only the desired section.

FIG. 6 is a flowchart illustrating a detailed process of configuring a 3D input model (S300). In the detailed process of FIG. 6, the control module 10 calls the entire structural system simple model from the storage module 14 (S301), and designates a unit group, that is, a unit member (S302). Then, the designated unit group is called (S303), and if there is a unit group to be added, steps S302 to S304 are repeatedly performed to 1 to N of the unit group, and when the repetition is completed, the model of the entire structural system is stored. Stored in the module 14 (S305).

Next, FIG. 7 is a flowchart illustrating a detailed process of inputting damage information into the 3D input model (S400). In the detailed process of FIG. 7, the control module 10 calls the unit member in which the damage has occurred in the storage module 14 (S401), and then disassembles the called unit member (S402). This shows that the unit member in which the damage occurred in FIG. 16 is called, and the unit member is disassembled in FIGS. 17 to 19. Here, the reinforcement girder of the bridge is shown as an example. In addition, the tree structure is automatically generated in the program of FIG. 16, and when the tree structure formed on the left side of FIG. 16 is selected by clicking, the corresponding detailed member is displayed. The tree structure of FIG. 16 may be implemented as in the example of FIG. 32.

The movement of the furnace may be expressed as follows, and may be described as shown in FIG. 21.

In addition, a method of searching for detailed members of the unit member by navigating is applied. The navigation applied in the present invention is to search the inside or outside of the unit member by a movement method of a camera using a keyboard or a mouse, and two methods are used to move the camera. In other words, there are first person and track ball methods. First Person navigates the inside of the unit member like zoom in / out while the camera moves to the first person view. Track Ball method assumes a virtual sphere on the screen It moves along the surface of the furniture and searches the outside of the unit member. The above equations are used to decompose and express the unit member, and may be programmed in software in the control module 10.

In addition, the control module 10 designates an input position of damage information (injury type information, damage class information, additional information) from the detailed member of the unit member in step S402 (S403). This is shown in FIG. In FIG. 23, a sticker corresponding to the input position is called and generated from the sticker module 16 (S404), and in FIG. 24, sticker information is read and input from the sticker module 16 for each type of damage (S405). In addition, in FIG. 25, the damage grade for the corresponding sub-member is retrieved from the sticker module 16 and input (S406). Then, through the input module 11 inputs the photograph or video taken on the spot for the damaged detail member (S407). The additional information may be input by selecting a picture, a video, a comment, or voice information through a window formed under the monitor screen.

Furthermore, FIG. 26 shows stickers by damage type, and FIG. 27 exemplarily shows stickers by damage class. The stickers by damage type are expressed in the same shape or shape as the actual damage, and the stickers by damage class can be marked in color. The rating can be displayed in four to five levels, but can be displayed in a more simplified or subdivided form according to the user's needs.

Figure 28 shows that the sticker is attached to the upper surface of the reinforcement girder, Figure 29 is an illustration showing that the sticker is attached to the lower portion of the reinforcement girder.

On the other hand, when there are a plurality of damaged parts for the unit member is input by repeating the step (S403) to step (S407) (S409). When the input of the damage information of the unit member is completed, the damage information of the other unit member is generated and inputted by repeating steps S401 to S409 (S410).

Therefore, when the input of the damage information for the unit member is completed, in Fig. 30, the corresponding detailed member inputted the damage information to the entire structural system is expressed in color. And Figure 31 shows that the plurality of detailed members are expressed in color. In particular, when a plurality of damage information is input to one detail member, the color having the highest damage grade among the plurality of damage information is represented by the color of the entire detail member.

Meanwhile, steps S300 and S400 may also be performed by a program coding an algorithm directly through a programming language to be performed by a computer.

As such, when the input of the damage information (S400) and the detailed steps are completed, the damage information may be inquired (S500). In addition, damage information is recorded in the damage history information DB (S600). Then, in order to newly generate information on damage, steps S400 to S600 are repeatedly performed (S700). In addition, after changing the model of the facility, by repeating the steps (S100) to (S600) for the input of the damage information, it is possible to enter the overall system for the maintenance needs. All the damage history information on the damage of the facility performed through the steps (S400 ~ S800) is stored in the storage module 14 to be managed.

When generation and storage of information on all damages generated from the unit member to the detailed member of the corresponding facility is completed, another facility model is changed to sequentially repeat steps S100 to S700 to use a three-dimensional spatial model. It will be possible to enter and retrieve damage information for the facility.

In addition, in FIG. 32, when a user searches for damage information after inputting damage information of the corresponding facility, the user may search and confirm step by step by a tree structure. The step may be searchable from the unit member to the detail member and from the detail member to the more detailed member. This may provide the user with easier searching of the facility.

While the invention has been shown and described with respect to the specific embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims.
