In the embodiment of the present application, the graphic server 110 may include a hardware layer, an operating system layer running on top of the hardware layer, and an application layer running on the operating system layer.

In the process of a building engineering project, since different project stages or different suppliers respectively model the same building project, there are situations of multiple BIM files for modeling the same building project, and how to process the BIM data in the multiple BIM files on the building information model data processing system 100, the formation of unified and systematic project modeling data becomes an urgent problem to be solved.

In view of the above existing problems, the following describes the implementation steps of the building information model data processing method, and please refer to fig. 3. Fig. 3 is a schematic flow chart of a method for processing building information model data according to an embodiment of the present application, where the method includes:

s310, the electronic equipment uploads the first file and the second file to the graphic server.

The first file and the second file may be Building Information Modeling (BIM) files for Modeling the first Building project. It will be appreciated that the first file and the second file are BIM files that model the same construction project.

The first file and the second file are two files generated by BIM software, and the BIM software may include RevitStructure, AutoCAD, ArchiCAD, Bentley System, Tekla Structures, digitalprject, and the like.

S320, if the file format of the first file is the same as that of the second file, the graphic server judges whether the software version of the first file is the same as that of the second file.

It should be noted that currently, the commonly used BIM software mainly includes RevitStructure, AutoCAD, ArchiCAD, Bentley System, Tekla structure, and Digital Project, and different BIM software have different file formats, such as rvt (revit) format of RevitStructure software, dgn (design) format of Bentley System software, and dwg (drawing) format of AutoCAD software. Because different BIM software lacks a uniform file storage standard and different BIM software has different support capabilities for the file format, the conversion process of the file format easily causes the loss of model data and influences the processing process of the BIM data in the BIM file. In the embodiment of the application, multiple BIM files with the same file format are uploaded to the graphics server through the electronic device, so that the error condition when the graphics server processes the BIM data in the multiple BIM files is avoided.

Specifically, the file format may include one of the following: RVT format, DGN format, DWG format, IFC format, OBJ format, 3DS format, or SKP format.

Because multiple software versions may be issued to the same BIM software, and different software versions may have different attribute descriptions, shape structures, sizes, or the like for the same component, in order to avoid an error condition that the software versions are different among multiple BIM files and thus the BIM data is processed, the embodiment of the present application needs to determine whether the software versions among the multiple BIM files are the same.

In one possible example, determining whether the software version of the first file is the same as the software version of the second file may include: the graphics server recognizes that the first file and the second file are files generated by the first software by a suffix name of the first file and a suffix name of the second file, and transmits the first file and the second file to the server of the first software, and the server of the first software may be configured to perform the following operations: detecting whether the software version of the first file is the same as that of the second file or not, and sending a detection result to the graphic server; or converting the first file into a first binary file through a preset identification plug-in running on the graphic server, analyzing character information in the first binary file to acquire first software version information, converting the second file into a second binary file, and analyzing character information in the second binary file to acquire second software version information; and determining whether the software version of the first file is the same as the software version of the second file according to the first software version information and the second software version information.

It should be noted that since files generated by different BIM software have different file suffix names, for example, the suffix name of a file generated by RevitStructure software is. rvt, the BIM software corresponding to the file can be determined by judging the suffix name of the file, and the software version of the file can be judged by the server of the BIM software. In addition, since the same name of a file suffix may exist in many BIM software, the embodiment of the present application may further obtain software version information of the file through a preset identification plug-in running on the graphics server, where the plug-in is a program written by an application program interface conforming to a certain specification, and may be used as a file editing tool and run on a system platform (e.g., the graphics server) specified by the program.

Specifically, determining whether the software version of the first file is the same as the software version of the second file according to the first software version information and the second software version information may include the following operations: if the first software version information is the same as the second software version information, the software version of the first file is the same as the software version of the second file; or if the first software version information is different from the second software version information, the software version of the first file is different from the software version of the second file.

Therefore, the server of the first software or the preset identification plug-in firstly judges the software version of the first file and the software version of the second file, so that errors caused by different software versions between the first file and the second file in the process of processing the BIM data in the first file and the BIM data in the second file can be avoided.

In one possible example, after determining whether the software version of the first file is the same as the software version of the second file, the following operations may be further included: in the case that the software version of the first file is not the same as the software version of the second file, sending an update request to the server of the first software, where the update request may be for the server of the first software to: updating a lower software version of the software versions of the first file and the second file into a first software version, and sending the updated first file and the updated second file to the graphic server; or under the condition that the software version of the first file is different from that of the second file, the lower software version of the first file and the software version of the second file is updated to the second software version through a preset updating plug-in running on the graphic server.

In particular, the first software version may include one of: the software version of the first file is different from the software version of the second file, and the software version of the first file is different from the software version of the second file. It should be noted that, in the process of upgrading the BIM software, there may be a case where a certain software version needs to significantly update primitives, components, and the like in the BIM software, or a case where a certain software version needs to be updated for a long time, so that when there are multiple software versions spanning between a low software version and a high software version, updating from the low software version to the high software version may cause loss of data of some primitives, components, and the like or a long update time, and therefore, in the embodiment of the present application, it may be considered that the low software version is updated to a software version between the low software version and the high software version, which is beneficial to avoid loss of data or a long update time.

In particular, the second software version may include one of: one software version between the software versions of the first and second files, a higher one of the software versions of the first and second files, a preset software version stored in the graphics server.

Therefore, the software version of the first file or the software version of the second file is updated through the server of the first software or the preset updating plug-in, so that the error result in the processing of the BIM data in the first file and the BIM data in the second file is reduced.

S330, under the condition that the software version of the first file is the same as that of the second file, the graphic server analyzes the first file to obtain first BIM data and analyzes the second file to obtain second BIM data.

Specifically, the first BIM data may be three-dimensional or two-dimensional model data formed of geometric information in the first file and non-geometric information in the first file.

It should be noted that the geometric information may include geometric information of the component, and the geometric information of the component may include geometric description information and geometric information. Wherein, the geometric description information may be description of geometric shape, for example, for a component having a triangle, the geometric description information may be length information of three sides of the triangle and included angle degree information of three vertices; the geometry information may be the geometry of the member in the BIM data. Further, the non-geometric information may include primitives, component attributes, component materials, component coordinates, component classification trees, floors, spaces, rooms, drawings, and the like. The primitives are basic units constituting a building model and can be divided into model primitives, annotation primitives, reference primitives and view primitives, and the model primitives can include body primitives and member primitives. The main body primitive is used for representing a main body component in an actual building, such as a wall, a floor slab, a roof, a stair and the like, and the parameter setting of the main body primitive is preset by BIM software; the component primitives are the most basic primitives in building project modeling, constitute structures in actual construction, such as beams, columns, trusses, reinforcing steel bars and the like, and are flexible and changeable in parameter setting; the annotation primitive is used for describing and explaining the model in detail, such as dimension marking, text annotation, marking, symbols and the like, and can be designed by a user; the reference primitives are used for providing a framework for placing and positioning model primitives, such as axis network, elevation, reference plane and the like; the view primitives are view representations generated based on the BIM file, and each view can set the visibility, level of detail, and scale of the building blocks it displays, as well as the range of views that the view can display, such as floor plan, elevation, cut-away, three-dimensional, detail, list, and the like.

For example, referring to fig. 4, fig. 4 is a schematic structural diagram of first BIM data and second BIM data. The three-dimensional view of the first BIM data 410 is mainly formed by a first floor, a second floor, a third floor and a roof, and each floor is formed by walls, reinforcing steel bars, floor slabs, stairs, various spaces, windows and the like. Likewise, the three-dimensional view of the second BIM data 420 is mainly formed by the first floor, the second floor, the third floor, and the roof, and each floor is formed by walls, reinforcing bars, floor slabs, stairs, various spaces, windows, and the like. Further, the second floor of the first BIM data 410 has a window 4101 thereon, and the second floor of the second BIM data 420 has a window 4102 thereon, and the window 4101 and the window 4201 are two different members.

In particular, the second BIM data may include unstructured data formed from geometric information in the second file and structured data formed from non-geometric information in the second file.

S340, the graphic server determines target data from the first BIM data and the second BIM data and sends the target data to the electronic equipment.

Specifically, the target data may be a difference component between the first BIM data and the second BIM data, or may be a difference primitive between a designated area in the first BIM data and a target area in the second BIM data.

It should be noted that, when the graph server successfully parses the first BIM data and the second BIM data, the graph server may compare each component in the first BIM data with each component in the second BIM data, and use a difference component between the first BIM data and the second BIM data as target data; alternatively, the graphics server may compare the specified region in the first BIM data with the target region in the second BIM data, and use a difference primitive between the specified region and the target region as the target data. Wherein the designated area in the first BIM data may represent an area designated in the instruction received from the electronic device, such as an instruction for designation to a toilet on the first floor in fig. 4.

The case where the difference component between the first BIM data and the second BIM data is taken as the target data is specifically described below.

In one possible example, determining the target data from the first BIM data and the second BIM data may include the operations of: acquiring first parameter information corresponding to a first component in first BIM data and second parameter information corresponding to a second component in second BIM data; judging whether the first component is the same as the second component or not according to the first parameter information and the second parameter information; in the case where the first member is not identical to the second member, the first member and the second member are regarded as target data.

It should be noted that the first component may be one component of all the components in the first BIM data, and the second component may be one component of the second BIM data having the same position information as the first component, that is, by performing a comparison operation on the components of the first BIM data and the second BIM data having the same position information.

Specifically, the first parameter information may include at least one of: a component property of the first component, a component Identifier (ID) of the first component, a material of the first component, a geometric dimension of the first component, or a component coordinate of the first component. It should be noted that the component property of the first component may include at least one key-value pair consisting of a property name and a property value.

For example, in the case where the first member is a door, the member attribute of the door may include < category name: door >, < kind ID: -2000014>, < construction type ID: GSP4P >, < thermal conductivity: 3.6886>, < thermal resistance: 0.2711>, < floor: first floor >, < door handle height: 900> key-value pairs; the door can be made of wood material; the door geometry may include width 2200, frame width 30, height 2550, etc.

Since it is necessary to ensure that two members to be compared have the same position information when performing a comparison operation on all members in the first BIM data and all members in the second BIM data, how to acquire the members in the first BIM data or the second BIM data, and how to acquire two members having the same position information, the following description will be made in detail.

In one possible example, acquiring first parameter information corresponding to a first component in the first BIM data and second parameter information corresponding to a second component in the second BIM data may include the following operations: sectioning the first BIM data along a horizontal plane, and performing orthographic projection on the H plane to obtain a first building plan; sectioning the second BIM data along a horizontal plane, and performing orthographic projection on the H plane to obtain a second building plan; acquiring first coordinate information corresponding to an intersection point of an axis A and the axis 1 on a first building plan and second coordinate information corresponding to an intersection point of the axis A and the axis 1 on a second building plan; selecting a first member from all members on the first building plan, and calculating the distance from the first member to the first coordinate information to obtain at least one piece of third coordinate information; taking a member having the same distance from the second building plan to the second coordinate information as the at least one third coordinate information as a second member; and acquiring first parameter information corresponding to the first component and second parameter information corresponding to the second component.

It should be noted that, since all components in the first BIM data and all components in the second BIM data need to be compared, when there are multiple floors in the first BIM data, the embodiment of the present application considers that a horizontal plane cut and an orthographic projection are performed on each floor to obtain at least one building plan, that is, the first building plan may include at least one building plan. Further, in the building plan view, the horizontal axis numbers are sequentially labeled with arabic numerals in order from left to right, and the vertical axis numbers are sequentially labeled with capitalized latin letters in order from bottom to top.

For example, please refer to fig. 5, 6 and 7. In fig. 5, since the three-dimensional view of the first BIM data 510 is mainly formed by the first floor, the second floor, the third floor, and the roof, the three-dimensional model data 510 is cut along a horizontal cutting plane and orthographically projected onto the H-plane, and a building plan 520 of the first floor, a building plan 530 of the second floor, a building plan 530 of the third floor, and a building plan 550 of the roof are obtained. In fig. 6, the building plan 610 is a detailed distribution diagram of the building plan 530 of the second floor. In the building plan view 610, the horizontal axis numbers are sequentially marked with numbers 1-6 from left to right, the vertical axis numbers are sequentially marked with numbers A-E from bottom to top, the axis A and the axis 1 intersect at an intersection 620, and the coordinate information corresponding to the intersection 620 is (x0, y 0); at the same time, the member 630, i.e., the window 5101 of the second floor is selected from all the members on the building plan view 610. In fig. 7, after picking to the member 630, first, the graphic server calculates the distance from the member 630 to the intersection 620 to obtain coordinate information { (x1, y1), (x2, y2) … }; then, at least one member, which is the same as the coordinate information { (x1, y1), (x2, y2) … } and includes a window 7101 of the first floor, a window 7102 of the second floor, and a window 7103 of the third floor, at a distance from the intersection of the a axis and the 1 axis on the building plan 720 of the first floor, the building plan 730 of the second floor, the building plan 740 of the third floor, and the building plan 750 of the roof, which are cut by the second BIM data 710, is acquired; finally, parameter information of each of the member 630, the window 7101, the window 7102, and the window 7103 is acquired.

Specifically, selecting the first member from all the members on the first building plan may include the following operations: forming a first circular area by taking the first coordinate information as an origin and a preset threshold as a radius; traversing the members within the first circular area in a counterclockwise direction starting from the a-axis on the first building plane; and selecting a first member from the members obtained by traversing. It should be noted that, in the embodiment of the present application, it may be considered that, in the components obtained by traversal, the components are sequentially selected from small to large or from large to small through the area size of the components to obtain the first component. It can be seen that the preset circular area is determined in the first building plan by taking the intersection point of the axis A and the axis 1 as the origin, and members in the preset circular area are traversed along the anticlockwise direction; then, all the members on the first building plan are traversed by continuously changing the radius of the preset circular area.

For example, in fig. 6, a circular area is formed by using the coordinate information (x0, y0) corresponding to the intersection 620 as an origin and using a preset threshold as a radius; then, traversing the members within the circular region in a counterclockwise direction from the A-axis; finally, the member 630, i.e., the window 5101 of the second floor is selected from the traversed members according to the area size of the member.

Specifically, calculating the distance from the first member to the first coordinate information to obtain at least one third coordinate information may include the following operations: obtaining at least one vertex on the geometry of the first member; and calculating the distance from the at least one vertex to the first coordinate information to obtain at least one third coordinate information. It should be noted that, in the embodiment of the present application, the coordinate information of the first member on the first building plane is determined according to the vertex on the geometric shape of the first member, for example, if the geometric shape of the first member is a quadrangle, the distances from four vertices on the quadrangle to the intersection point of the a axis and the 1 axis are calculated, so as to obtain the coordinate information of the first member.

It can be seen that the building plane graph is obtained by performing horizontal plane sectioning and orthographic projection on the first BIM data and the second BIM data, two members with the same coordinate information on the building plane are quickly and simply obtained according to the coordinate information of the intersection point of the distance A axis and the distance 1 axis on the building plane graph, and the operations are sequentially repeated, so that the operations of comparing and integrating all the members in the first BIM data with all the members in the second BIM data are facilitated.

The following embodiment of the present application will specifically describe how to determine whether the first component and the second component are the same according to the first parameter information and the second parameter information.

In one possible example, in a case where the first parameter information includes a component attribute of the first component, and the second parameter information includes a component attribute of the second component, determining whether the first component and the second component are the same according to the first parameter information and the second parameter information may include the operations of: traversing an attribute value corresponding to each attribute name in the component attribute of the first component to obtain at least one first attribute value, and traversing an attribute value corresponding to each attribute name in the component attribute of the second component to obtain at least one second attribute value; comparing the relationship between the at least one first attribute value and the at least one second attribute value to obtain a first comparison result; whether the first member and the second member are identical is determined according to the first comparison result.

Specifically, determining whether the first member and the second member are the same according to the first comparison result may include the following operations: if the first comparison result is that each attribute value in the at least one first attribute value is equal to each attribute value in the at least one second attribute value, the first member and the second member are the same; or, if the first comparison result is that there is an unequal attribute value between the at least one first attribute value and the at least one second attribute value, the first component and the second component are different.

For example, in fig. 5, 6, and 7, the member attribute of the member 630 may include < category name: window >, < floor: second floor >, < heat transfer coefficient: 3.6886>, < thermal resistance: 0.2711 >; the member attributes of the window 7101 may include < category name: window >, < floor: first floor >, < heat transfer coefficient: 3.6886>, < thermal resistance: 0.2711 >; the member attributes of the window 7102 may include < category name: window >, < floor: second floor >, < heat transfer coefficient: 3.6886>, < thermal resistance: 0.2711> and the member properties of the window 7103 may include < category name: window >, < floor: second floor >, < heat transfer coefficient: 3.6886>, < thermal resistance: 0.2711 >. Since the attribute value corresponding to a floor in the member attribute of the member 630 is different from that of the window 7101 and the window 7103, the member 630 is a different member from the window 7101 and the window 7103.

S350, the electronic equipment sends a first operation processing request aiming at the target data to the graphic server.

Wherein the first operation processing request may be for requesting the graphics server to perform one of the following operations: deleting the target data, modifying the target difference data, retaining the target data or changing the display form of the target data.

Specifically, the display form of the change target data may include reducing the target data, enlarging the target data, changing the mark color of the target data, and the like.

S360, the graphic server processes the first BIM data and the second BIM data according to the first operation processing request, integrates the processed first BIM data and the processed second BIM data to form a third file, and sends the third file to the electronic equipment.

It should be noted that the graphics server processes the first BIM data and the second BIM data modeled for the same building project according to the operation processing request from the electronic device, for example, delete the difference component, amplify the difference component, and integrate the processed first BIM data and the processed second BIM data to form the same file, so that multiple BIM files modeled for the same building project are integrated on the graphics server, and unified modeling data are formed.

Referring to fig. 8, fig. 8 is a schematic flow chart of another building information model data processing method according to an embodiment of the present application, where the method includes:

s801, uploading the first file and the second file to a graphics server by the electronic device.

Wherein the first file and the second file may be BIM files modeling the first construction project. It will be appreciated that the first file and the second file are BIM files that model the same construction project.

S802, if the file format of the first file is the same as that of the second file, the graphics server judges whether the software version of the first file is the same as that of the second file.

S803, under the condition that the software version of the first file is the same as the software version of the second file, the graphics server parses the first file to obtain the first BIM data, and parses the second file to obtain the second BIM data.

S804, the graphic server sends the first indication information to the electronic equipment.

The first indication information may be used to indicate that the parsing status of the first file is completed and the parsing status of the second file is completed. It should be noted that, because the electronic device receives the first indication information, the electronic device knows that the graphics server has successfully parsed the BIM data in the first file and the BIM data in the second file, and therefore the electronic device can process the BIM data in the first file and the BIM data in the second file.

S805, the electronic device sends a second operation processing request for the first region on the first BIM data to the graphics server.

The second operation processing request may be used to request the graphics server to compare the first region on the first BIM data with the second BIM data.

It should be noted that the first area on the first BIM data may be a specific building area on the first BIM data, such as a room, a kitchen, a floor, a toilet, etc. In addition, the graphics server only needs to receive an operation processing request of the electronic equipment for the first BIM data, and the first BIM data and the second BIM can be automatically compared by the graphics server.

For example, in fig. 4, the user needs to check the difference of the building layout between the second floor on the first BIM data 410 and the second floor on the second BIM data 420, and as can be seen from fig. 6, the building layout of the second floor may include spaces such as bedrooms, objects, study rooms, toilets and balconies, and may further include pixels such as windows in the spaces, doors in the spaces, and reference planes where the spaces are located. Then, the electronic device receives an instruction of a user for comparing the second floor on the first BIM data 410 with the second BIM data 420, generates an operation processing request for the second floor on the first BIM data 410 according to the instruction, and sends the operation processing request to the graphics server.

S806, the graphics server determines a target area having the same coordinate information as the first area on the second BIM data according to the second operation processing request.

It should be noted that, in order to compare the first area on the first BIM data with the second BIM data, the embodiment of the present application considers that the graphics server automatically acquires the target area on the second BIM data, which has the same coordinate information as the first area, and directly compares the first area with the target area. How to determine the target area having the same coordinate position as the first area on the second BIM data according to the second operation processing request is described in detail below.

In one possible example, determining the target area having the same coordinate position on the second BIM data as the first area according to the second operation processing request may include the operations of: according to the second operation processing request, making horizontal plane sectioning on the first BIM data along the layer where the first area is located, and making orthographic projection on the H surface to obtain a third building plan; acquiring at least one piece of fourth coordinate information of the first area on the third building plane graph from the intersection point of the A axis and the 1 axis; sectioning the second BIM data along a horizontal plane, and performing orthographic projection on the H plane to obtain a fourth building plan; and taking the area equal to the at least one fourth coordinate information in the fourth building plan as the target area.

For example, in fig. 4, the user needs to view the building layout difference between the toilet of the second floor on the first BIM data 410 and the toilet of the second floor on the second BIM data 420; secondly, the electronic device receives an instruction for comparing the toilet of the second floor on the first BIM data 410 with the second BIM data 420 from the user, generates an operation processing request for the toilet of the second floor on the first BIM data 410 according to the instruction, and sends the operation processing request to the graphics server; thirdly, the graphic server performs horizontal plane sectioning and orthographic projection on the first BIM data 410 along the layer where the toilet of the second floor is located according to the operation processing request to obtain a building plan (such as the building plan 530 of the second floor); then, the graph server acquires coordinate information of an intersection point of the distance A axis and the 1 axis of the toilet of the second floor on the building plane graph; finally, the building plan of the second BIM data 420 (e.g., the building plan 720 of the first floor, the building plan 730 of the second floor, the building plan 740 of the third floor, and the building plan 750 of the roof) is obtained, and the toilet of the second floor on the second BIM data 420 is found in the building plan according to the above-mentioned coordinate information.

Specifically, the obtaining of at least one fourth coordinate information of the first area on the third building plan from the intersection point of the a axis and the 1 axis may include the following operations: acquiring at least one vertex on the geometry of the first region; and calculating the distance from the at least one vertex to the intersection point of the A axis and the 1 axis to obtain at least one fourth coordinate information.

Therefore, the graphic server performs horizontal plane sectioning and orthographic projection on the first BIM data along the layer where the first area is located according to the operation processing request from the electronic device to obtain the building plan, and quickly and simply acquires the target area with the same coordinate information as the first area on the second BIM data according to the coordinate information of the first area on the building plan, so that the processing operations such as comparison and integration of the first area in the first BIM data and the target area in the second BIM data are facilitated.

S807, the graphics server compares each primitive in the first area with each primitive in the target area to obtain a second comparison result.

And S808, the graphics server takes the difference graphic primitive in the second comparison result as target data and sends the target data to the electronic equipment.

And S809, the electronic equipment sends a first operation processing request aiming at the target data to the graphic server.

Wherein the first operation processing request may be for performing one of the following operations: deleting the target data, modifying the target difference data, retaining the target data or changing the display form of the target data.

S810, the graphic server processes the first BIM data and the second BIM data according to the first operation processing request, integrates the processed first BIM data and the processed second BIM data to form a third file, and then sends the third file to the electronic device.

It should be noted that the related technical solution and example related to the building information model data processing method described in fig. 8 are consistent with the related technical solution and example related to fig. 3, and are not described in detail here.

It can be seen that, in the embodiment of the present application, first, since the electronic device uploads the multiple BIM files with the same file format, which are modeled for the same building project, to the graphics server, it is beneficial to reduce errors in BIM data processing caused by different file formats existing among the multiple BIM files. Secondly, in order to further reduce an error in the BIM data processing due to different software versions among the plurality of BIM files, the embodiment of the present application needs to determine whether the software versions among the plurality of BIM files are the same. Then, the graphics server sends the first indication information to the electronic device, and the graphics server receives an operation processing request from the electronic device for the BIM data in the plurality of BIM files, so that interaction between the graphics server and the electronic device is realized. And finally, the graphics server processes the BIM data in the plurality of BIM files according to the operation processing request from the electronic equipment and integrates the processed BIM data to form the same file, so that the integration of the plurality of BIM files for modeling the same building project is realized, and unified project modeling data is formed.
