In accordance with the above-described embodiment, the following describes the execution steps of the electronic document processing method from the viewpoint of a method example, referring to fig. 2. Fig. 2 is a flowchart of a method for processing an electronic file, provided in an embodiment of the present application, applied to an electronic device 100 including a processor 110 and an AI module 120, where the method includes:

s210, the electronic equipment acquires a first electronic file for building floor modeling, and analyzes the first electronic file to obtain first BIM data.

It should be noted that, the electronic device 100 parses the first electronic file by the AI module 120 in the internal structure to obtain the first BIM data, and stores the first BIM data in the memory 130 in the electronic device. Since AI module 120 may directly invoke the first BIM data in memory 130, a data processing operation is facilitated.

Specifically, the first electronic file may include a computer aided design (computer aideddesign, CAD) drawing for building floor modeling, a building information model (Building Information Modeling, BIM) file, and the like. Further, the first electronic file may be a file created by BIM software, which may include AutoCAD, revitStructure, archiCAD, bentley System, tekla Structures, digital Project, and the like.

Specifically, the first BIM data may include geometric information in the first electronic file and non-geometric information in the first electronic file.

In particular, the geometric information in the first electronic file may include geometric information of each component in the first electronic file, and the geometric information of the component may include geometric description information of the component and geometric information of the component. Wherein the geometry descriptive information is used to represent a description of the geometry of the component, for example, for a component having a triangle, the geometry descriptive information may include length information of each side of the triangle and included angle degree information of each vertex; the geometry information may be used to represent the geometry of the component.

Specifically, the non-geometric information in the first electronic file may include component attribute information, component Identifier (ID) information, component material information, component coordinate information, and the like.

It should be noted that the member may also be referred to as a primitive, and the primitive is a basic unit constituting one building model, and may be divided into a model primitive, an annotation primitive, a reference primitive, and a view primitive. Wherein the model primitives may include a subject primitive and a component primitive. The main body graphic element is used for representing main body components in an actual building, such as walls, floors, roofs, stairs and the like, and the parameter setting of the main body graphic element is preset by BIM software; the component graphic elements are the most basic graphic elements in building project modeling, constitute structures in actual construction, such as beams, columns, trusses, steel bars and the like, and are flexible and changeable in parameter setting; annotation primitives are used to describe and interpret the model in detail, such as size annotations, text annotations, labels, symbols, etc., and can be designed by the user himself; the reference primitives are used to provide a framework for placement and positioning of model primitives, such as an axis net, elevation, reference plane, etc.; the view primitives are view representations generated based on the BIM file, and each view may set the visibility, the degree of detail, and the scale of the components it displays, as well as the view range that the view can display, such as floor plan, elevation, cross-sectional, three-dimensional, detail, and the like.

Further, the component attribute information may include at least one key value pair composed of an attribute name and an attribute value.

For example, referring to fig. 3, fig. 3 is a schematic structural diagram of data in the first electronic file. The data 310 in the first electronic file is BIM data modeled for building floors. Wherein the three-dimensional view of the data 310 in the first electronic file is primarily formed of a first floor, a second floor, and a third floor, and each floor is formed of walls, rebar, floors, stairs, various spatial areas, windows, doors, and the like.

The following describes in detail how the electronic device 100 parses the first electronic file to obtain first BIM data.

In one possible example, parsing the first electronic file to obtain first BIM data may include the following operations: determining a two-dimensional building plan modeled by the first electronic file for each of the first building floors to obtain at least one first two-dimensional building plan; acquiring axis network data on a first two-dimensional building plan, wherein the axis network data comprises an axis A and an axis 1; determining component data corresponding to at least one second component on the first two-dimensional building plan according to the A axis and the 1 axis, wherein the component data corresponding to the at least one second component comprises geometric information of each component in the at least one second component and non-geometric information of each component in the at least one second component; and taking the axis network data and the component data corresponding to the at least one second component as first BIM data.

It should be noted that, the electronic device 100 determines at least one first two-dimensional building plan by the AI module 120 in the internal structure, and then determines the component data corresponding to at least one second component according to the a-axis and the 1-axis in the axis network data. Further, since there are multiple floors of the first building floor, the present embodiments contemplate determining, by AI module 120, a two-dimensional building plan in which the first electronic file is modeled for each floor, with the network axes in the two-dimensional building plan including lateral axes labeled sequentially from left to right by arabic numerals and longitudinal axes labeled sequentially from bottom to top by uppercase latin letters, thereby enabling determination of the first BIM data from the network axes in the two-dimensional building plan.

For example, please refer to fig. 4 and 5. In fig. 4, the first building floor comprises a first floor, a second floor and a third floor, so the data 410 in the first electronic file modeled for the first building floor is mainly formed by the first floor, the second floor and the third floor; the electronic device then determines a two-dimensional building plan modeled by the first electronic file for each of the first building floors to obtain a two-dimensional building plan 420 for the first floor, a two-dimensional building plan 430 for the second floor, and a two-dimensional building plan 430 for the third floor. In fig. 5, two-dimensional building plan 510 is a specific distribution diagram of two-dimensional building plan 430 for the first floor. Firstly, in the axis network data of the two-dimensional building plan 510, the transverse axis is composed of axes sequentially labeled in the order of 1-5 numbers from left to right, and the vertical axis is composed of axes sequentially labeled in the order of A-D numbers from bottom to top; then, the electronic device determines all components in the two-dimensional building plan 510 according to the a-axis and the 1-axis, such as a wall around a living room area, a window in the living room area, a door in the living room area, a stair in the living room area, a wall around a bedroom area, a window in the bedroom area, a door in the bedroom area, a wall around a bathroom area, a wall around a kitchen area, a wall around a restaurant area, a wall around a bedroom area, a door in the bedroom area, a window in the bedroom area, a wall around the bathroom area, a door in the bathroom area, and the like, and determines geometric information of all components and non-geometric information of all components; finally, the axis net data of the two-dimensional building plan 510, the geometric information of all the components, and the non-geometric information of all the components are used as electronic devices to analyze the BIM data of the first electronic file for the first floor of the first building floors. Similarly, the electronic device parses out BIM data of the first electronic file for a second one of the first building floors and BIM data of the first electronic file for a third one of the first building floors.

The following describes in particular how the electronic device 100 determines a two-dimensional building plan for which the first electronic file is modeled for each of the first building floors to obtain at least one first two-dimensional building plan.

In one possible example, determining a two-dimensional building plan modeled by the first electronic file for each of the first building floors to obtain at least one first two-dimensional building plan may include the operations of: identifying at least one first layer of the first electronic file modeled for each floor in the first building project; and cutting the first electronic file along a horizontal plane according to at least one first image layer, and performing orthographic projection on an H plane to obtain at least one first two-dimensional building plan.

It should be noted that, the electronic device 100 recognizes at least one first primitive by the AI module 120 in the internal structure, and obtains at least one first two-dimensional building plan according to the at least one primitive. In addition, the BIM software creates data such as components within each of the building floors on different layers and constructs a three-dimensional view through the multiple layers when creating the first electronic file for modeling the building floors. Therefore, the embodiment of the application considers that the first electronic file is cut along the horizontal plane according to the layer, and orthographic projection is carried out on the H plane to obtain the two-dimensional building plane layer corresponding to each of the building floors.

In the following, it is described in detail how the electronic device determines the component data corresponding to at least one second component on the first two-dimensional building plan from the a-axis and the 1-axis.

In one possible example, determining component data corresponding to at least one second component on the first two-dimensional building plan from the a-axis and the 1-axis may include the operations of: identifying an intersection point between the A axis and the 1 axis to obtain a first intersection point; forming a region to be identified on the first two-dimensional building plan according to the first intersection point which is a round point and the preset threshold value which is a radius; sequentially identifying the components in the area to be identified in a clockwise direction starting from the 1 axis to obtain at least one second component; determining geometric information of each of the at least one second member according to a coordinate information set of each of the at least one second member in a preset two-dimensional coordinate system, wherein the preset two-dimensional coordinate system is constructed by taking a first intersection point as an origin, taking an A axis as an X axis and taking a 1 axis as a Y axis; non-geometric information of each of the at least one second component is determined based on the component attribute information of each of the at least one second component.

It should be noted that, the electronic device 100 identifies the first intersection point by the AI module 120 in the internal structure, forms the area to be identified according to the first intersection point as a dot and the preset threshold value as a radius, identifies at least one second component in the area to be identified, and finally obtains component data corresponding to the at least one second component. In addition, the embodiment of the application may sequentially acquire the coordinate information of each of the at least one second member in the preset two-dimensional coordinate system in consideration of the order of the sizes of the areas of the passing members from the at least one second member obtained by recognition from small to large or from large to small.

In particular, the preset threshold may be dynamically varied by the electronic device 100, so that all the elements within the first two-dimensional building plan, i.e. the at least one second element, are identified by constantly changing the preset threshold, i.e. by constantly changing the radius of the preset identification area.

For example, referring to fig. 6, first, the electronic device identifies an intersection 620 between the a-axis and the 1-axis in the two-dimensional building plan 610; secondly, the electronic device forms a region 630 to be identified in the two-dimensional building plan 610 according to the intersection 620 as a round dot and the preset threshold r as a radius; again, the electronic device starts from the 1-axis to identify components within the area to be identified 630 in sequence in a clockwise direction to obtain a window 640 within the living room area; the electronic device then calculates all tops in window 640 in the living room areaCoordinate information set of point-to-intersection 620 { (x) _1,1 ,0),(x _1,2 ,0),...,(x _1,m 0) and according to the set of coordinate information { (x) _1,1 ,0),(x _1,2 ,0),...,(x _1,m 0) obtaining geometric information such as geometric shape information, vertex coordinate information, geometric dimensions, geometric areas and the like of the window 640 in the living room area; meanwhile, the electronic device determines the member attribute information of the window 640 in the living room area (e.g.<Category name: window >、<Category ID: -2000010>、<Construction type ID: GSPTP>、<Thermal conductivity coefficient: 3.0>、<Thermal resistance: 0.28>、<Floor: bottom building>A pair of equal key values; window material is glass material, etc.) to obtain geometric information of the window 640 in the living room area; finally, the electronic device traverses and identifies the component data corresponding to all components in the two-dimensional building plan 610 by continuously changing the preset threshold r.

The BIM software commonly used at present mainly comprises RevitStructure, autoCAD, archiCAD, bentley System, tekla Structure, digital Project and the like, and electronic files created by different BIM software have different file formats, such as RVT (ReViT) format of Revitstructure software, DGN (Design) format of Bentley System software, DWG (DraWing) format of AutoCAD software and the like. Because of the lack of unified file storage standards between different BIM software and the different BIM software's support capability for file formats, the embodiments of the present application also contemplate storing electronic files having different file formats in different data tables. The following will specifically describe.

In one possible example, before parsing the first electronic file to obtain the first BIM data, the electronic device further performs the following operations: identifying a file format of the first electronic file to obtain a first file format; and storing the first electronic file in a third data table in a preset data classification table corresponding to the first file format.

It should be noted that, the electronic device 100 recognizes the file format of the first electronic file by the AI module 120 in the internal structure, and stores the first electronic file in the third data table. It may be appreciated that before the electronic device parses the first electronic file, the first electronic file may be classified and stored in the data table according to a file format of the first electronic file, so that the electronic device 100 reads or retrieves, from the preset classification table, the electronic file corresponding to the file format through the file format, thereby facilitating improvement of efficiency of executing the reading or retrieving operation on the stored electronic file.

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

Specifically, the preset data classification table may be a data table obtained by dividing the storage data area of the memory 130 in the electronic device 100 according to a predetermined setting. The preset data classification table comprises a first data table, a second data table and a third data table. The first data table may be used to store geometric information of the component, the second data table may be used to store non-aggregate information of the component, and the third data table may be used to store electronic files having the first file format. It may be appreciated that, in the internal structure of the electronic device 100, the storage data area of the memory 130 is divided into the first data table, the second data table and the third data table according to a predetermined setting, and each data table has a respective function to store different types of BIM data or electronic files, so that the electronic device 100 may store the BIM data or electronic files in a classified manner through the storage data area of the memory 130 in the internal structure, so that the subsequent AI module 120 directly reads or retrieves the corresponding BIM data or electronic files from the preset classified data table in the memory 130, thereby facilitating to improve the efficiency of performing the reading or retrieving operation for the stored BIM data or electronic files.

Specifically, identifying the file format of the first electronic file to obtain the first file format may include the following operations: converting the first electronic file into a binary file through a preset identification plug-in; and analyzing character information in the binary file to obtain a file format of the first electronic file as a first file format.

It should be noted that, the electronic device 100 invokes the preset recognition plug-in from the AI module 120 in the internal structure, and the preset recognition plug-in recognizes the file format of the first electronic file, 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 device specified by the program (such as the electronic device 100). In addition, since the character information in the binary file is convenient to analyze, the embodiment of the application considers that the first electronic file is converted into the binary file through the preset identification plug-in, so that the efficiency of identifying the file format of the first electronic file is improved through analyzing the character information in the binary file.

S220, the electronic device preprocesses the first BIM data to obtain second BIM data.

Wherein the preprocessing may be used to delete the component data of the first BIM data that relate to at least one first component of the same geometry information and component attribute information, the component data of the first component corresponding including the geometry information of the first component and the non-geometry information of the first component.

It should be noted that, the electronic device 100 preprocesses the first BIM data by the AI module 120 in the internal structure to obtain the second BIM data. In addition, since the geometric information of the first component includes the geometric description information of the first component and the geometric information of the first component, the non-geometric information of the first component includes the component attribute information, the component identifier information, the component material information and the component coordinate information of the first component, and the geometric information and the component attribute information have a great influence on the components of the BIM software in creating the electronic file, the embodiments of the present application only judge the components related to the same geometric information and component attribute information, thereby providing the processing efficiency for the first BIM data. Meanwhile, by deleting the component data corresponding to at least one first component related to the same geometric shape and component attribute information in the first BIM data, the data amount of BIM data needing to be stored is reduced, and the data redundancy is reduced.

For example, in FIG. 6, the electronic device calculates a set of coordinate information { (x) for all vertices to intersection 620 in window 650 in bedroom A region _2,1 ,0),(x _2,2 ,0),...,(x _2,m 0) and according to the set of coordinate information { (x) _2,1 ,0),(x _2,2 ,0),...,(x _2,m 0) to obtain the geometric information of the window 650 in the bedroom a region; when the geometry information of the window 650 in the bedroom a region is the same as the geometry information of the window 640 in the living room region, and the component attribute information of the window 650 in the bedroom a region is the same as the component attribute information of the window 640 in the living room region, the electronic device may delete the window 640 in the living room region or the window 650 in the bedroom a region and store.

S230, the electronic device stores a first geometric information set in the second BIM data in a first data table in a preset data classification table, and stores a first non-geometric information set in the second BIM data in a second data table in the preset data classification table.

The following describes the steps performed in the electronic document processing method from the viewpoint of an example of the method, referring to fig. 9. Fig. 9 is a flow chart of yet another electronic document processing method according to an embodiment of the present application, applied to a processing server 710, where the method includes:

s910, the electronic equipment uploads a first electronic file modeled for the building floor to the processing server.

S920, the processing server acquires the first electronic file and analyzes the first electronic file to obtain first BIM data.

It should be noted that, the processing server 710 parses the first electronic file by the processor 810 in the internal structure to obtain the first BIM data, and stores the first BIM data in the memory 130 in the electronic device. Since the processor 810 may directly call the first BIM data in the memory 840, the data processing operation is facilitated.

The following describes in detail how processing server 710 parses the first electronic file to obtain first BIM data.

It should be noted that, the processing server 710 determines at least one first two-dimensional building plan by the processor 810 in the internal structure, and then determines the component data corresponding to at least one second component according to the axis a and the axis 1 in the axis network data. Further, since there are multiple floors of the first building floor, embodiments herein contemplate determining, by processor 810, a two-dimensional building plan for which the first electronic file is modeled for each floor, with the net axes in the two-dimensional building plan including lateral axes labeled sequentially from left to right by arabic numerals and longitudinal axes labeled sequentially from bottom to top by uppercase latin letters, thereby enabling determination of the first BIM data from the net axes in the two-dimensional building plan.

In the following, it is described in detail how the processing server 710 determines a two-dimensional building plan modeled by the first electronic file for each of the first building floors to obtain at least one first two-dimensional building plan.

It should be noted that, the processing server 710 identifies at least one first primitive by the processor 810 in the internal structure, and obtains at least one first two-dimensional building plan according to the at least one primitive. In addition, the BIM software creates data such as components within each of the building floors on different layers and constructs a three-dimensional view through the multiple layers when creating the first electronic file for modeling the building floors. Therefore, the embodiment of the application considers that the first electronic file is cut along the horizontal plane according to the layer, and orthographic projection is carried out on the H plane to obtain the two-dimensional building plane layer corresponding to each of the building floors.

In the following, it is described in detail how the processing server 710 determines the component data corresponding to at least one second component on the first two-dimensional building plan from the a-axis and the 1-axis.

It should be noted that, the processing server 710 identifies the first intersection point by the processor 810 in the internal structure, forms the area to be identified according to the first intersection point as a dot and the preset threshold value as a radius, identifies at least one second component in the area to be identified, and finally obtains component data corresponding to the at least one second component. In addition, the embodiment of the application may sequentially acquire the coordinate information of each of the at least one second member in the preset two-dimensional coordinate system in consideration of the order of the sizes of the areas of the passing members from the at least one second member obtained by recognition from small to large or from large to small.

In particular, the preset threshold may be dynamically varied by the processing server 710, so that all the elements within the first two-dimensional building plan, i.e. at least one second element, are identified by constantly changing the preset threshold, i.e. by constantly changing the radius of the preset identification area.

In one possible example, before parsing the first electronic file to obtain the first BIM data, the processing server further performs the following operations: identifying a file format of the first electronic file to obtain a first file format; and storing the first electronic file in a third data table in a preset data classification table corresponding to the first file format.

It should be noted that, the processing server 710 recognizes the file format of the first electronic file by the processor 810 in the internal structure, and stores the first electronic file in the third data table. It can be appreciated that before the electronic device parses the first electronic file, the first electronic file may be classified and stored in the data table according to a file format of the first electronic file, so that the subsequent processing server 710 reads or retrieves, from the preset classification table, the electronic file corresponding to the file format through the file format, thereby facilitating improvement of efficiency of performing the reading or retrieving operation on the stored electronic file.

Specifically, the preset data classification table may be a data table obtained by dividing the storage data area of the memory 840 in the processing server 710 according to a predetermined setting. The preset data classification table comprises a first data table, a second data table and a third data table. The first data table may be used to store geometric information of the component, the second data table may be used to store non-aggregate information of the component, and the third data table may be used to store electronic files having the first file format. It will be appreciated that, in the internal structure of the processing server 710, the storage data area of the memory 840 is divided into a first data table, a second data table and a third data table according to a predetermined arrangement, and each data table has a respective function to store different types of BIM data or electronic files, so that the processing server 710 can store the BIM data or electronic files in a classified manner through the storage data area of the memory 840 in the internal structure, so that the subsequent processor 810 can directly read or retrieve the corresponding BIM data or electronic files from the preset classified data table in the memory 840, thereby being beneficial to improving the efficiency of performing the reading or retrieving operation for the stored BIM data or electronic files.

It should be noted that, the processing server 710 invokes a preset identifying plug-in from the processor 810 in the internal structure, and the preset identifying plug-in identifies the file format of the first electronic file, 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 device specified by the program (such as the processing server 710). In addition, since the character information in the binary file is convenient to analyze, the embodiment of the application considers that the first electronic file is converted into the binary file through the preset identification plug-in, so that the efficiency of identifying the file format of the first electronic file is improved through analyzing the character information in the binary file.

S930, the processing server pre-processes the first BIM data to obtain second BIM data

It should be noted that, the processing server 710 pre-processes the first BIM data by the processor 810 in the internal structure to obtain the second BIM data. In addition, since the geometric information of the first component includes the geometric description information of the first component and the geometric information of the first component, the non-geometric information of the first component includes the component attribute information, the component identifier information, the component material information and the component coordinate information of the first component, and the geometric information and the component attribute information have a great influence on the components of the BIM software in creating the electronic file, the embodiments of the present application only judge the components related to the same geometric information and component attribute information, thereby providing the processing efficiency for the first BIM data. Meanwhile, by deleting the component data corresponding to at least one first component related to the same geometric shape and component attribute information in the first BIM data, the data amount of BIM data needing to be stored is reduced, and the data redundancy is reduced.

S940, the processing server stores the first geometric information set in the second BIM data in a first data table in a preset data classification table, and stores the first non-geometric information set in the second BIM data in a second data table in the preset data classification table.

In one possible example, before storing the first set of geometric information in the second BIM data in the first data table in the preset data class table and the first set of non-geometric information in the second BIM data in the second data table in the preset data class table, the processing server further performs the following operations: dividing second BIM data according to a first data table in a preset data classification table to obtain a first geometric information set; dividing the second BIM data according to a second data table in a preset data classification table to obtain a first non-geometric information set. It is understood that the processing server 710 divides the second BIM data according to the existing data table in the preset data classification table by the processor 810 in the internal structure, and obtains the corresponding geometric information set and/or non-geometric information set.
