Abstract
Description
Technical Field
[0001] This invention relates to the field of data processing technology, and in particular to a method, apparatus, device, and storage medium for exporting data. Background Technology
[0002] In the field of architectural modeling, when a BIM (Building Information Modeling) model is created using modeling software, it needs to be exported as a standard data file conforming to common data standards in order to facilitate data review or data transfer. Existing data export solutions generally parse data for a specific data standard and then convert it into a specific standard data file. However, existing data export methods have the following drawbacks: (1) The data export process is relatively complex and does not separate the data acquisition process from the data export process, resulting in the two processes being mixed together and unable to be reused for a specific process; (2) The export process can only be applied to a specific data standard, with poor extensibility and scalability. The export process cannot be applied to another data standard or different versions of the same specific data standard. Therefore, how to export BIM model data into a standard data file conforming to data standards more efficiently has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.
[0039] Example 1
[0040] This invention provides a method for exporting data, such as... Figure 1 As shown, the method specifically includes the following steps:
[0041] Step S101: When an export instruction is received, a target configuration file corresponding to the target data standard is selected from the preset library; wherein, a corresponding configuration file is pre-created for each type of data standard in the preset library.
[0042] In this embodiment, after a user creates a BIM model, they can trigger an export command to convert the information in the BIM model into standard data conforming to the target data standard and store it as a standard file for subsequent data transmission or data review. When the user triggers the export command, they specify the target data standard; that is, the export command includes the target data standard. The target data standard can be one of the following: IFC (Industry Foundation Classes) data standard, GFC (Glodon Foundation Classes) data standard, or Xiong'an XDB data standard. It should also be noted that the target data standard can be different versions of the above three data standards, such as the Shenzhen SZ-IFC data standard or the Hunan HN-IFC data standard.
[0043] In this embodiment, corresponding configuration files are created in advance for different types of data standards. These configuration files are used to determine the original model data to be exported during the export process, as well as to convert the original model data into standard data that conforms to the target data standard. By creating multiple configuration files, it is possible to complete the export operation of multiple data standards through a single export process, making the export process reusable.
[0044] Step S102: Obtain the data to be exported from the created BIM model according to the target configuration file.
[0045] The data to be exported includes: the object to be exported and additional information of the object to be exported; the object to be exported includes at least one of the following: building unit, building floor height, building component; the additional information includes: attribute information and / or shape information.
[0046] In this embodiment, the data to be exported that needs to be standardized can be filtered out from the BIM model through the target configuration file, and only the determined data to be exported is standardized and exported; by exporting data in a targeted manner, the efficiency of data export can be improved and the complexity of export can be reduced.
[0047] Step S103: Convert the data to be exported into standard data that conforms to the target data standard according to the target configuration file.
[0048] In this embodiment, once the data to be exported is determined, it is converted into standard data according to the mapping rules corresponding to that data in the target configuration file. These mapping rules include, but are not limited to, matching data types, unifying units, unifying names, and converting attribute value types. For example, if a certain attribute data in a BIM model is a numeric type, but the target data standard defines this data as a string, then mapping processing is required according to the corresponding mapping rules in the configuration file. By using preset mapping rules, the data to be exported can be accurately converted into standard data, improving the accuracy of data export.
[0049] Step S104: Store all converted standard data in a preset standard file and save it.
[0050] The process involves writing all the converted standard data into the standard file according to the format of the target data standard to complete the data export process.
[0051] This embodiment simplifies the data export process by dividing it into a data acquisition process and a data export process, and enables reusable processing of the basic process. The entire export process is clearer, which not only improves R&D efficiency but also reduces R&D costs. This embodiment can be adapted to different types of data standards and different versions of the same data standard, greatly expanding the scope of the export function.
[0052] Specifically, after step S101, the method further includes:
[0053] Step A1: Load the read / write API interfaces contained in the Software Development Kit (SDK) of the target data standard according to the target configuration file;
[0054] Step A2: Generate an empty standard file corresponding to the target data standard by calling the read / write API interface.
[0055] In this embodiment, after obtaining the target configuration file of the target data standard, the SDK package of the target data standard is first obtained, and then the read / write API interface is obtained from the SDK package. The read / write API interface is used to generate a standard file for storing the converted standard data, and finally the read / write API interface is used to write the converted standard data into the standard file according to the format of the target data standard.
[0056] Specifically, step S102 includes the following steps:
[0057] Step B1: Based on the exported object components in the configuration file, determine the objects to be exported from the BIM model; wherein, the objects to be exported include: building units, building floors, and building components;
[0058] Step B2: Iterate through each object to be exported in sequence, and obtain the original attribute data of the currently exported object according to the object attribute component corresponding to the currently exported object in the configuration file.
[0059] Furthermore, step S102 also includes:
[0060] Step B3: Obtain project data according to the project module in the configuration file; wherein the project data includes at least one of the following: type information of the target data standard, file name of the target configuration file, name information of the modeling software used to create the BIM model, and version information of the modeling software used to create the BIM model.
[0061] In this embodiment, the project module is used to obtain project software-level information, which is written into the schema when generating standard files. Specifically, the project module is used to obtain data from the following fields: Function (type information of the target data standard), ConfigName (file name of the target configuration file), AppName (name information of the modeling software that creates the BIM model), and Version (version information of the modeling software that creates the BIM model).
[0062] In this embodiment, to adapt to different export data standards, the configuration file adopts XML format and features a multi-module, multi-level, and multi-field design. Specifically, the configuration file includes a project module and an export object module. The export object module further includes an export object component and an object attribute component. Each of these components contains multiple fields. The project module allows access to project-level data information, while the export object component in the export object module identifies the objects to be exported from the BIM model that require standardized conversion. Furthermore, the export object module sets corresponding object attribute components for each type of export object to retrieve the original attribute data of the corresponding export object.
[0063] It should be noted that the raw attribute data here corresponds to the additional information of the objects to be exported mentioned above; the data to be exported includes: project data, objects to be exported, and raw attribute data of each object to be exported.
[0064] Specifically, step S103 includes the following steps:
[0065] Each object to be exported is traversed sequentially. Based on the mapping rules in the object attribute component corresponding to the currently traversed object, the original attribute data of the currently traversed object is converted into standard attribute data that conforms to the target data standard.
[0066] It should be noted that, in addition to the attribute fields that need to be standardized, the object attribute component also sets corresponding mapping rules for each attribute field. These attribute fields allow the acquisition of raw attribute data of the object to be exported from the BIM model, while the mapping rules convert the acquired raw attribute data into standard attribute data. For example, an object attribute component includes: Name (original model attribute name), ExportName (attribute name in the data standard), ExportValveType (attribute value type in the data standard), and Unite (attribute unit in the data standard); where Name is the field used to acquire raw attribute data, and ExportName, ExportValveType, and Unite constitute the mapping rules.
[0067] Specifically, step S104 includes the following steps:
[0068] Step C1: Write the project data into the standard file by calling the read / write API interface;
[0069] Step C2: By calling the read / write API interface, all standard attribute data is written into the standard file according to the format of the target data standard for caching;
[0070] Step C3: Obtain the hierarchical relationship data between each object to be exported from the BIM model, and write the hierarchical relationship data into the standard file by calling the read / write API interface.
[0071] In this embodiment, after obtaining the raw data according to the configuration file and converting the raw data into standard data, it is also necessary to call the read / write API interface in the SDK package of the target data standard to write the standard data into a pre-generated standard file in the format required by the target data standard and save it.
[0072] Specifically, after step S104, the method further includes:
[0073] Step D1: During the process of obtaining the data to be exported from the BIM model according to the target configuration file, the data to be exported that cannot be obtained is written into the preset export report;
[0074] Step D2: During the process of converting the data to be exported into the standard data according to the target configuration file, the data to be exported that cannot be converted into the standard data is written into the preset export report.
[0075] During the data export process, there may be instances where writing to the standard file fails. In this embodiment, after saving the standard file, all failed export data will be compiled into an export report, which will then be returned to the user so that they can understand the export status. The export report records all missing data and export error records from the data export process.
[0076] like Figure 2 The diagram shown is a schematic of a complete export process given in this embodiment. Figure 2 As shown, the export process includes five steps: Step 1: Load Configuration, which loads the configuration file and read / write API and generates an empty standard file; Step 2: Data Acquisition, which obtains individual building information, floor information, and component information from the BIM model; Step 3: Export Processing, which standardizes the acquired information. Since some objects to be exported have no attributes or shapes, attribute and shape conversions can be performed optionally; Step 4: Process Hierarchical Relationships, which writes the converted standard data and hierarchical relationship data into the standard file; Step 5: Save File, which saves the standard file for subsequent data exchange or data review.
[0077] This embodiment can be adapted to various data standards, and the adaptation process is relatively simple, which greatly improves development efficiency. It can also handle various types of data review and provide error reports for exported data, which can be displayed to the user.
