Abstract
Description
Technical Field
[0001] This application relates to the field of railway engineering construction, and in particular to a method and apparatus for processing building information models. Background Technology
[0002] Building Information Modeling (BIM) is currently being widely used in construction applications. BIM technology allows for multi-purpose use of a single model, enabling different application stages to be completed on a single model, thus significantly saving labor costs. In recent years, research on BIM-based forward design in the design phase has yielded fruitful results and has gradually been implemented in engineering projects. BIM-based forward design uses a 3D BIM model as its starting point and data source to complete the entire process from schematic design to construction drawing design. During the construction phase, BIM can be used to design temporary construction buildings, construction roads, slope excavation, earthwork balance, material quarrying, production and processing systems, and construction layout.

[0025] It should be understood that Figure 1 The number of terminal devices, networks, and servers shown is merely illustrative. Depending on implementation needs, any number of terminal devices, networks, and servers can be included.
[0026] Figure 2 A flow 200 of one embodiment of the building information model processing method of this disclosure is shown.
[0027] like Figure 2 As shown, the building information model processing method of this embodiment may include the following steps:
[0028] Step 201: Obtain the source building information model.
[0029] In this embodiment, the entity executing the building information model processing method (e.g., Figure 1 The server 105 or terminal devices 101, 102, 103 shown acquire the source building information model through various means. Here, the source building information model can be the BIM from the design phase, that is, the BIM resulting from the design completed by the designers.
[0030] Step 202: Analyze the source building information model to determine the component set and the geometric attribute information, international dictionary framework encoding, and non-geometric attribute information of each component.
[0031] The executing entity can parse the source Building Information Model (BIM) to determine various parameters. These include the component set and the geometric attributes of each component, its International Framework for Dictionaries (IFD) encoding, and non-geometric attribute information. Here, components can be parts used in the railway industry, such as roadbed drainage ditches and earthwork components. By parsing the source BIM, all included components can be identified, thus obtaining the component set. Geometric attribute information can include the component's length, mileage, dimensions, and other geometric information. The IFD encoding is used. Non-geometric attribute information can include materials, construction methods, and other non-geometric attributes.
[0032] Step 203: Based on the component set and geometric attribute information, determine the element set and the element identifier and sub-geometric attribute information of each element.
[0033] The implementing entity can divide the component sets and geometric attribute information according to the division standards of the sub-projects and sub-items of the railway station pre-station linear engineering, determine the unit sets, and simultaneously determine the unit identifier and sub-geometric attribute information of each unit. Specifically, the implementing entity can fill the information obtained from the division into a pre-set standard data exchange template. The template header can include sub-project, sub-item, minimum unit length, and unit identifier.
[0034] The executing entity can generate a unit identifier for each unit in the unit set. Specifically, when generating a unit identifier, the identifiers of its respective division and sub-item can be combined, and the unit's location information within the component can also be considered. That is, the unit identifier can include information about its respective division and sub-item, as well as location information.
[0035] The executing entity can determine the sub-geometric attribute information of each component based on the geometric attribute information of the component set. Specifically, the executing entity can divide the geometric attribute information of the component set according to the position information of each component to obtain the sub-geometric attribute information of each component.
[0036] Step 204: Determine the mapping relationship between the above unit identifiers and the engineering decomposition structure code, the international dictionary frame code, and the non-geometric attribute information.
[0037] The implementing entity can establish a mapping relationship between unit identifiers and Engineering Breakdown Structure (EBS) codes, International Dictionary Frame (IFD) codes, and non-geometric attribute information. The purpose of this is to determine the minimum unit length through a unique EBS code. The Engineering Breakdown Structure is decomposed and coded according to the engineering equipment and facilities classification coding standard. In the entire Building Information Model (BIM), the information management of the entire building lifecycle primarily relies on the EBS coding system.
[0038] Specifically, the executing entity can first establish a mapping relationship between unit identifiers and EBS codes, and then establish a mapping relationship between EBS codes and IFD codes and non-geometric attribute information. Combining the two, the above mapping relationship is obtained.
[0039] Step 205: Construct the target building information model based on the mapping relationship, unit set, and sub-geometric attribute information.
[0040] After establishing the aforementioned mapping relationship, the executing entity can determine each unit in the unit set and its sub-geometric attribute information based on this relationship. This allows them to construct the target building information model based on the information of the smallest unit. Specifically, the executing entity can input this information into the application used to construct the target building information model to obtain the aforementioned BIM.
[0041] The building information model processing method provided in the above embodiments of this disclosure can process BIM in the design stage and modify it into BIM in the construction stage, thereby improving the construction efficiency of BIM in the construction stage and saving time and effort.
[0042] See also Figure 3 This illustrates a flow 300 of another embodiment of the building information modeling processing method according to the present disclosure. For example... Figure 3 As shown, the method in this embodiment may include the following steps:
[0043] Step 301: Obtain the source building information model.
[0044] Step 302: Analyze the source building information model to determine the component set and the geometric attribute information, international dictionary framework encoding, and non-geometric attribute information of each component.
[0045] In some optional implementations of this embodiment, the executing entity can import the source Building Information Model (BIM) into an application used to construct the BIM, thereby obtaining various information contained therein. Specifically, the executing entity can combine a preset information template to obtain the effective information contained therein. The aforementioned information template may include sub-projects, sub-items, minimum unit length, unit identifiers, etc.
[0046] Step 303: Divide each component in the component set according to the preset division criteria to obtain a unit set composed of the unit subsets corresponding to each component; generate a unit identifier for each unit in the unit set; determine the sub-geometric attribute information of each unit according to the division criteria and geometric attribute information.
[0047] The executing entity can obtain a set of components by parsing the source building information model. The executing entity can then divide this set of components according to a preset partitioning standard to obtain corresponding unit sets. This partitioning standard can be a minimum process unit breakdown standard. Specifically, the set of components may include components such as "drainage ditch" and "cavity". By partitioning them according to the aforementioned standard, the unit subset corresponding to the drainage ditch can include three minimum process units for a "cast-in-place reinforced concrete drainage ditch" and five minimum process units for a "mortar-grouted masonry drainage ditch".
[0048] After dividing the components, the executing entity can generate a unit identifier for each unit. Specifically, the executing entity can generate unit identifiers based on the position of each unit within the component, or it can randomly generate unit identifiers for each unit.
[0049] The executing entity can also divide the geometric attribute information corresponding to the component set according to the division criteria, thereby obtaining the sub-geometric attribute information corresponding to each unit. The sub-geometric attribute information here can be the length, position, etc. of each unit.
[0050] Step 304: Determine the first mapping relationship between the unit identifier and the engineering breakdown structure code; determine the second mapping relationship between the engineering breakdown structure code and the international dictionary framework code and attribute information; determine the mapping relationship based on the first mapping relationship and the second mapping relationship.
[0051] After determining the unit identifiers for each unit, the executing entity can first establish a primary mapping relationship between the unit identifier and the EBS code. Since the classification of EBS codes is contained within IFD codes, the two codes cannot be directly mapped; therefore, the IFD codes need to be combined with the non-geometric attributes of the components. First, the parent class of the component is located using the EBS code; for example, the parent class of the EBS code "reinforced concrete drainage ditch" is "drainage ditch". The IFD code is then located using the parent class, and finally, the secondary mapping relationship between the EBS code and the component is determined using the non-geometric attribute information of that type of component. Figure 4 This illustrates the mapping between EBS codes and IFD codes for roadbed drainage ditches, superimposed with non-geometric attributes. By combining the first and second mapping relationships, the mapping relationships between unit identifiers, EBS codes, IFD codes, and non-geometric attribute information can be determined. After determining these mapping relationships, the executing entity can determine the unit identifier using the IFD code and non-geometric attribute information, and thus determine the minimum unit length for each unit.
[0052] Step 305: Determine the start and end points of each component in the component set; starting from the start point, reconstruct the component according to the mapping relationship and the sub-geometric attribute information of each unit in the unit set, until the end point, to obtain the target building information model.
[0053] When constructing the target building information model, the executing entity can first determine the start and end points of each component. The start and end points of the components can be obtained by parsing the source building information model. Since the minimum unit length of each unit can be determined based on the above mapping relationship, a configuration form is formed. Thus, when reconstructing the target building information model, the minimum unit length in the configuration form can be extracted as the length parameter of the preceding components, and reconstruction can be achieved based on a parameterized method. Specifically, the executing entity can start from the start point of each component and deploy each unit of each component until the end point of the component, thereby reconstructing the component. After each component is reconstructed, the target building information model can be obtained. That is, using the start and end point mileages S and E of the original components, and the minimum unit length L obtained through the mapping relationship... min , with L min The integer part of the equation (S) is used to obtain the number of reconstructed segments n+1. Starting from S, n segments are reconstructed, with the starting mileage of the last segment being S+L. min *n, with the endpoint at E.
[0054] In some optional implementations of this embodiment, the minimum unit length of the configuration form can be adjusted according to actual needs. Specifically, if the executing entity receives modification information for the minimum unit length, it can construct the target building information model based on the modified minimum unit length.
[0055] Step 306: Determine the position of each unit in the unit set according to the mapping relationship; generate a serial number based on the above positions.
[0056] Similarly, after determining the location of each unit based on the mapping relationship, the executing entity can generate a serial number by combining the aforementioned locations. It is understandable that when generating the serial number, information about the component, construction procedures, etc., can also be incorporated.
[0057] Step 307: Add geometric attribute information, non-geometric attribute information, engineering decomposition structure code, and serial number to the target building information model.
[0058] In order to enable the target building information model to be used directly in the construction phase, the implementing entity can add geometric attribute information, non-geometric attribute information, engineering breakdown structure code, and serial number to the target building information model.
[0059] In some specific implementations, the executing entity can add geometric and non-geometric attribute information to each component in the target building information model; add engineering decomposition structure codes to each component in the target building information model according to the mapping relationship; and add serial numbers to each unit in the target building information model.
[0060] The building information model processing method provided in the above embodiments of this disclosure can directly parse the BIM in the design stage and then generate the BIM in the construction stage, thereby eliminating the need for technicians to spend a lot of time and effort on reconstruction and improving efficiency.
