Detailed Description

In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the disclosed embodiments. However, it will be apparent to one skilled in the art that the present disclosure may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present disclosure with unnecessary detail.

In the field of building construction, a large number of drawings, such as design drawings, construction drawings, completion drawings and the like, are involved in the whole flow operation of the whole building construction, and the drawings may be checked and modified at each stage of the building construction process, and the modification of the drawings can be regarded as the change of the drawings. Because the prior change hanging mode based on offline change paper files draws change information to a construction blueprint has the following problems:

1) because the change hooking is completed on the basis of the paper version files on line, the problems of loss, damage and the like of the change drawing files are easy to occur in the practical process of the actual scene.

2) The versions of the change and construction blueprints are various, and the association relationship between the change and construction blueprints is established by simply depending on the text description, so that the problems of disordered corresponding relationship between the change and construction blueprints and the like are easily caused.

3) The incidence relation between the change drawing and the construction blueprint is established by means of text description, changes need to be hung on the construction blueprint in a mode of manually drawing a cloud line on the construction blueprint, the time consumption of the hanging process is long, and errors are prone to occurring.

Therefore, a scheme is needed to be provided, which can reduce the difficulty of change hooking operation, avoid the change hooking error caused by manually drawing a cloud line, avoid the confusion of the corresponding relation between the change and the drawing, avoid the loss of documents such as paper change explanation and drawing, improve the change hooking efficiency of the construction blueprint, and realize automatic change hooking.

The following describes a relationship between a change and a construction blueprint, taking the construction blueprint in the field of real estate building construction as an example, with reference to the accompanying drawings. FIG. 1 is a schematic diagram of a relationship between a change and a construction blueprint in an actual application scenario. As shown in fig. 1, the relationship between the change and the construction blueprint mainly includes the following contents:

the drawing change may also be referred to as a design change, and the change may include both a description of the change and a drawing change. The change instruction can be based on the drawing standard of the national construction drawing, and can supplement, confirm and modify the problems of error, omission, collision, deficiency and the like in the original construction blueprint, and the change instruction can describe changed position information, change reasons and other information (such as material information of objects and the like) which cannot be described by depending on geometric figures and three-dimensional sizes in the drawing in a text form.

The alteration drawing may be a drawing generated according to an alteration of an original drawing, where the alteration drawing is used to indicate a modification made to the original drawing (such as an original construction blueprint), and the alteration drawing may only include a modified geometric figure corresponding to a modification position, so that the alteration drawing may be regarded as a patch file generated after the original drawing is modified. In an actual scene, the change drawings are not directly drawn on the construction blueprints, and the drawings for guiding construction are independently provided, and after all the construction of the building is completed, all the change drawings and the construction blueprints are uniformly combined to form a completion drawing. The change drawing is a drawing file which is independently provided for modifying the original drawing, so that the change drawing can be regarded as the change drawing corresponding to the original drawing.

In the existing scene of changing the construction blueprint, the change generally comprises a change description and a change drawing, wherein the change drawing is a drawing explanation of the change description, and the change description and the change drawing are combined to form a modification description for the construction blueprint; the changed drawings and the construction blueprints can be linked in a cloud coil casting mode, and a final as-built drawing is generated according to the construction blueprints and the changed drawings.

Here, the change refers to the change and adjustment of the construction blueprint, and in the prior art, the change is usually presented in the form of a paper document, and the changed paper document describes the information such as the occurrence position and the area on the construction blueprint in detail by means of characters besides the modification of the drawing itself by means of the form of the drawing. After the changed paper file is issued to the constructor, the constructor can know the information such as the position, the area and the like of the change on the construction blueprint according to the text description.

It should be noted that, the embodiment of the present disclosure is described by taking a construction blueprint in the field of building construction as an example, however, the change hooking scheme provided by the embodiment of the present disclosure is not limited to the construction blueprint nor to the drawings in the field of building construction, and other scenarios that require establishing a connection between a change drawing and an original drawing based on the change drawing are also applicable. The execution main body of the embodiment of the disclosure may be a change hooking tool in an intelligent drawing system for building construction, or an independent change hooking system, and the application scenario and the execution main body do not limit the disclosure.

Fig. 2 is a schematic flow chart of a method for modifying a hooking connection based on a drawing according to an embodiment of the present disclosure. The drawing-based change hooking method in fig. 2 may be executed by a server, and as shown in fig. 2, the drawing-based change hooking method may specifically include:

s201, acquiring an original drawing file and a changed drawing file generated after changing the drawing of the original drawing file;

s202, converting the original drawing file and the changed drawing file into an original drawing file and a changed drawing file which meet the requirement of a preset type and have a unified format;

s203, based on the original drawing files with the uniform format and the shaft network data in the changed drawing files, associating the drawings of the changed drawing files with the uniform format to the drawings of the original drawing files with the uniform format by using a circle note hanging mode so as to establish an association relationship between the changed drawing files with the uniform format and the original drawing files with the uniform format;

and S204, acquiring the circle note attribute, generating a rewriting file according to the circle note attribute, and performing rewriting operation on the original drawing file by using the rewriting file so as to rewrite the circle note graph to the original drawing file.

Specifically, the original drawing file may be a drawing file corresponding to the construction blueprint, the original drawing file may be stored in a drawing library of the system server in advance, when the corresponding original drawing file is changed, the server calls the original drawing file, and the change is hooked on the line in a cloud coil annotation manner according to the uploaded change drawing, so that an association relationship between the change drawing and the original drawing is established. The original drawing file can be a two-dimensional drawing file or a three-dimensional drawing file, and the drawing format of the original drawing file can be DWG, RVT, SKP, 3DS and other formats.

The shaft net is a net formed by building axes drawn in a building drawing, comprises a linear shaft net, an oblique shaft net, an arc shaft net and the like, and consists of a positioning axis (such as the central line of a wall or a column in a building structure), a mark size (such as the distance between the positioning axes of a marked building) and a shaft number. The shaft net is a main frame for building drawing, main supporting members of the building are positioned and arranged according to the shaft net, the well-known and orderly effect is achieved, and the shaft number is a number defined by the shaft line.

Further, the alteration drawing includes a geometric figure corresponding to the modification position of the original drawing, for example: the length of a section of stair in the original drawing is 15 sections, the length of the stair is changed into 17 sections by a construction designer, then the construction designer needs to independently draw a change drawing for the changed stair, and the change drawing comprises a stair with the length of 17 sections; and the change drawing also shows the shaft network where the stair is located, the shaft number of the shaft network is the same as that of the shaft network where the stair is located in the original drawing, and the position where the change occurs can be located through the shaft number corresponding to the shaft network, for example, the transverse shafts of the shaft network are B1 and B2, the longitudinal shafts of the shaft network are A1 and A2, and the region where the change occurs can be determined through the shaft network region composed of B1, B2, A1 and A2.

It should be noted that the modifying hanging may be regarded as inserting the modification into the original drawing according to the modification drawing, so as to implement annotation on the original drawing. For example, the original drawing is annotated in a cloud coil annotation mode to display the position and information of the change, and the change is hung in the original drawing, so that the incidence relation between the change drawing and the construction blueprint can be established, and a basis is provided for further realizing visual hanging display.

According to the technical scheme provided by the embodiment of the disclosure, an original drawing file and a changed drawing file generated after the drawing of the original drawing file is changed are obtained; converting the original drawing file and the change drawing file into an original drawing file and a change drawing file which meet the requirement of a preset type and have a unified format; based on the original drawing files with the uniform format and the shaft network data in the changed drawing files, associating the drawings of the changed drawing files with the uniform format to the drawings of the original drawing files with the uniform format by using a circle note hanging mode so as to establish an association relationship between the changed drawing files with the uniform format and the original drawing files with the uniform format; and acquiring the circle note attribute, generating a rewriting file according to the circle note attribute, and performing rewriting operation on the original drawing file by using the rewriting file so as to rewrite the circle note graph to the original drawing file. The automatic hooking device can realize automatic hooking between the change drawing and the original drawing without manual hooking operation by means of the change explanation of the paper edition, reduces time consumption of the change hooking operation, is not easy to cause hooking errors, and solves the problems that the change corresponding relation is disordered and the change explanation is easy to lose and damage and the like.

In some embodiments, obtaining a change drawing file generated after a drawing change for an original drawing file includes: after the geometric figures in the drawing of the original drawing file are modified, generating a modified drawing file according to the modified geometric figures and the axis network corresponding to the modified geometric figures; the original drawing file and the changed drawing file comprise a plurality of layer files, and each layer file corresponds to one layer in the drawing.

Specifically, the alteration drawing file is based on a drawing which is provided separately after geometric figures in the original drawing are modified, for example: in the actual construction process, the original 15 sections of stairs need to be changed into 17 sections of stairs, so that a 17-section stair needs to be drawn in a single drawing, and the drawing is the same as the axle network to which the 15 sections of stairs belong in the original drawing, and the drawing obtained according to the drawing mode can be used as a change drawing of the original drawing. The alteration drawing may only contain geometric figures and no text information.

Further, the layer is a concept in graphic software, for example, in a construction blueprint drawn by AutoCAD software, the construction blueprint may be a drawing formed by overlapping a plurality of layers. One layer in the drawing corresponds to one layer file, that is, the drawing data is actually stored in a layer data manner, that is, a complete drawing file includes layer files or layer data corresponding to all layers. In practical application, the alteration drawing may adopt a drawing file with the same format as the original drawing.

In some embodiments, converting the original drawing file and the alteration drawing file into the original drawing file and the alteration drawing file with unified formats meeting the requirements of predetermined types includes: respectively extracting corresponding geometric figure data and attribute data from the original drawing file and the changed drawing file by using a preset calling function; according to the data types corresponding to the geometric figure data and the attribute data and a preset conversion rule corresponding to the data types, performing conversion operation on the geometric figure data and the attribute data to obtain the geometric figure data and the attribute data meeting the preset type requirement; and regenerating an original drawing file and a changed drawing file in a unified format according to the geometric figure data and the attribute data which meet the preset type requirement.

Specifically, because the formats of drawings drawn by different graphic engines are different, and the graphic engines installed on different terminals may also be different, in order to facilitate loading and displaying of drawing files with different formats in the graphic engines of different terminals, the drawing files with different formats need to be converted into drawing files with a uniform format, so that the purpose of presenting the drawing files at multiple ends is achieved.

After the server receives the change drawing and the construction blueprint, the drawing conversion service is called to convert the drawing into the drawing with the general format, the drawing with the general format can be used by a web end engine and a mobile end engine, namely, the drawing with the general format can be opened by different graphic engines and renders geometric figures, and the drawing files with different formats can be opened by different engines by converting the drawing files with different formats into the uniform format. The method is convenient for a user to browse drawings in real time, measure, paint brush, layer management, cloud coil annotation, drawing comparison and other operations on the terminal provided with different graphic engines.

Further, the calling function may be considered as an API interface provided by the graphics software of the called object, and the API interfaces of different pieces of software may be configured in advance in a server of the auditing system, and specifically, an API interface installation package provided by different pieces of software may be obtained, and the API interface may be configured in a computing program corresponding to the format conversion service in the server through the installation package. It should be noted that, the embodiments of the present disclosure do not limit the specific content of the calling function (i.e., the API interface), and the calling functions provided by different graphics software are not the same. In practical applications, the API interface is provided by the service side of different graphics software, and therefore, the specific content of the calling function does not constitute a limitation to the present technical solution.

Geometry data includes, but is not limited to, the following geometries: points, lines, arcs, ellipses, parabolas, quadratic curves, polylines, NURBS curves, NURBS surfaces, planes, cylinders, spheres, and torus, and attribute data including, but not limited to, the following attributes: layer, view, color, material, style, and text.

It should be noted that drawing files in different formats are converted into drawing files in a unified format, where the unified format is a unique unified format generated based on the conversion scheme of the embodiment of the present disclosure, and the drawing files in the unified format may be opened by different software or graphics engines.

Here, by converting the drawing into the drawing in the general format, in the process, the database can keep the association between the drawing file in the original format and the drawing file in the general format, and the server can also find the drawing file in the general format corresponding to the drawing by querying the database while previewing the drawing by the engine of any port.

In some embodiments, performing a conversion operation on the geometry data and the attribute data according to a data type corresponding to the geometry data and the attribute data and a preset conversion rule corresponding to the data type includes: converting the geometric figure data and the attribute data into geometric figure data and attribute data meeting the requirements of a preset type according to a preset mapping relation of classes among different data types and a data conversion rule corresponding to the classes; wherein a class is used to represent a collection of objects having the same properties and construction as the geometry data and property data that meet the requirements of a predetermined type.

Specifically, in the embodiment of the present disclosure, a unified type library is preconfigured, and a mapping relationship between classes of different data object types is preconfigured in the unified type library, that is, a class, such as a linear class, a point class, and a circular arc class, is defined for a type to which each data object belongs. A class refers to a collection of a set of objects having the same properties and methods, which provides a uniform abstract description for all objects belonging to the class. In practical application, when defining the corresponding class for the data object, the attribute and the representation mode of the data object of the same type can be encapsulated into the class of the data object according to the requirements of the preset format of the invention on different data object types, that is, compared with the original data object, the attribute and the representation mode of the original data object can be constructed into the attribute and the representation mode defined by the format of the invention through the class. Thus, in the disclosed embodiments, a class may be considered as a way of constructing an object, i.e., according to which a data object of one class may be converted into an object of another class.

Further, in the embodiment of the present disclosure, conversion rules between different types of data objects may be written into a class (i.e., a construction manner), and functions of different data objects may be mapped to functions required by a uniform format through the conversion rules, and the conversion rules may be regarded as a conversion relationship of the functions. In the following, a description is given of a function conversion between information of data objects by using a conversion rule, taking a point as a data object as an example, where a function of a point pair in a DWG file is "origin ()"; the function at the point in the RVT is Rpoint (); the function of the point in the SKP file is Kpoint (); mapping the different function data to Lpoint () by using a conversion rule; through the operation, the points in the files with different formats can be converted into the points in the file with the uniform format. The content in the bracket may be parameter or attribute information of the point.

According to the technical scheme provided by the embodiment of the disclosure, the class of the data object in the initial format file is mapped to the class of the object in the uniform format of the invention through the uniform type library, and because the representation modes of the objects in the files in different formats are different, the functions of the objects in the files in different formats are corresponding to the functions of the objects in the format of the invention through the conversion rule, and the unification of the representation modes of the objects in the files in different formats is realized through the conversion, thereby achieving the unification of the data structure.

In some embodiments, associating the drawing of the changed drawing file with the drawing of the original drawing file with the unified format by using a circle annotation hooking mode based on the axle network data in the original drawing file with the unified format and the axle network data in the changed drawing file comprises: extracting first axle network layer data and second axle network layer data from an original drawing file and a changed drawing file with a uniform format respectively, and acquiring axle numbers in the first axle network layer data and the second axle network layer data; matching the axle number in the second axle network layer data with the axle number in the first axle network layer data so as to determine an axle network area corresponding to the drawing of the changed drawing file with the uniform format in the drawing of the original drawing file with the uniform format, and taking the axle network area as the changed area; according to the corresponding coordinates of the shaft network area in the drawings of the original drawing files with the uniform format, associating the drawings of the changed drawing files with the uniform format to the drawings of the original drawing files with the uniform format in a circle annotation hanging mode so as to mark the changed area in the drawings of the original drawing files with the uniform format; and the shaft network area is a closed area formed by the axis corresponding to the shaft number determined according to the matching result.

Specifically, in order to determine the changed hub axle network region according to the axle number in the change drawing, it is necessary to extract the hub axle network layer data in the original drawing file and the change drawing file, where the hub axle network layer data is a layer file corresponding to a hub axle network layer, and the hub axle network layer file is a file corresponding to a hub axle network layer of the drawing, and therefore, the hub axle network layer file includes data (such as the axle number) of all the hub axles corresponding to the drawing. Because the drawing generally corresponds to a plurality of layer files, the layer files can be identified according to the identifiers of the shaft network layer files, so that which layer files belong to the shaft network layer files can be judged, and the identified shaft network layer files can be extracted.

In some embodiments, matching the axle number in the second axis network layer data with the axle number in the first axis network layer data includes: and converting the shaft number into an ASCII code, comparing the ASCII code corresponding to the shaft number in the second shaft network layer data with the ASCII code corresponding to the shaft number in the first shaft network layer data, determining the shaft number with the same ASCII code, and taking the shaft number with the same ASCII code as a matching result.

Specifically, after the axle network layer data corresponding to the original drawing file and the modified drawing file are obtained, the axle numbers in the axle network layer data can be further obtained, the axle numbers corresponding to the respective drawing files are converted into ASCII codes, and the axle numbers can be searched through the ASCII codes.

According to the technical scheme provided by the embodiment of the disclosure, the axes with the same axis number can be quickly found by comparing the axis number in the construction blueprint with the axis number in the change blueprint, and the axis network area is quickly positioned according to the closed area formed by the axes, so that the changed area is further determined according to the axis network area, the efficiency of positioning the changed area is greatly improved, and the time consumed by hanging change is reduced.

In some embodiments, determining the corresponding axis network region of the drawing of the uniform-format alteration drawing file in the drawing of the uniform-format original drawing file comprises: according to the axle numbers with the same ASCII codes, determining the corresponding axle lines of the axle numbers with the same ASCII codes from the drawings of the original drawing files with the uniform format, determining a closed area formed by the axle lines in the drawings of the original drawing files with the uniform format, and taking the closed area as an axle network area; the axis numbers having the same ASCII code include a horizontal axis number and a vertical axis number corresponding to the axis network.

Specifically, the axle network may be considered as a network composed of axes, and in a layer displayed on a drawing, the axle network is arranged in a structure of a shape like a Chinese character jing, and a closed region in the middle of the shape like a Chinese character jing corresponds to an axle network region. That is to say, the embodiment of the present disclosure realizes the positioning of the modification area by comparing the shaft numbers between the modification drawing and the original drawing, that is, the shaft numbers are used to look up the shaft lines, and the closed area formed by the shaft lines is used as the area where the modification occurs (i.e., the area corresponding to the modified geometric figure). In practical applications, a complete axle network comprises at least four axes, namely two transverse axis and two longitudinal axis, and the four axes jointly enclose an axle network area.

In some embodiments, the coordinates corresponding to the hub area in the drawing of the unified format original drawing file include: determining the vertex coordinates of the closed graph corresponding to the axle network area in the drawing of the original drawing file with the uniform format according to the closed graph corresponding to the axle network area, calculating the geometric center point of the axle network area according to the vertex coordinates, and taking the geometric center point of the axle network area as a reference center point for hanging change.

Specifically, after the area of the axis network is determined, the position of the cloud loop note needs to be further determined according to the area of the axis network in combination with cloud line information, in practical application, the determination is performed by further calculating the relationship between the geometric center point of the cloud line and the axis network, that is, the coordinate of the geometric center point in the drawing corresponding to the area of the axis network is determined, and the reference point of the cloud loop note (that is, the center point of the cloud line) is determined according to the coordinate of the geometric center point.

Further, the axis network region may be an axis network region in the modified drawing or an axis network region in the original drawing, and since the final labeling of the cloud line modification is implemented in the original drawing, when the axis network region is the axis network region corresponding to the modified drawing, the coordinates of the axis network region corresponding to the modified drawing need to be mapped to the axis network region of the original drawing according to a transformation matrix between the coordinates of the modified drawing and the coordinates of the original drawing. In practical application, the transformation matrix may be defined according to a format corresponding to an actual drawing and a data requirement, and therefore, a detailed description is not provided.

In some embodiments, the method for hooking the note in a circle includes cloud note hooking, and associating the drawing of the changed drawing file with the uniform format with the drawing of the original drawing file with the uniform format by using the method for hooking the note in a circle so as to establish an association relationship between the changed drawing file with the uniform format and the original drawing file with the uniform format, including: and generating a cloud coil annotation layer corresponding to the change of the original drawing with the uniform format according to the coordinate of the reference center point and the cloud line attribute information, loading the cloud coil annotation layer into the original drawing file with the uniform format, and establishing a mapping relation among the ID of the changed drawing file, the ID of the cloud coil annotation layer and the ID of the original drawing file.

Specifically, the cloud coil label is presented in the original drawing in a layer mode, so that in order to establish an association relationship between the cloud coil label (which can represent a changed position) and the original drawing, after a reference central point corresponding to a cloud line is determined, the cloud coil label layer can be generated according to the reference central point and cloud line attribute information, the cloud coil label layer is loaded into a file of the original drawing, and when a graphic engine calls the original drawing file, the cloud coil label layer in the original drawing file can be loaded, so that a construction blueprint with the cloud coil label is rendered.

Further, the change drawing file and the original drawing file in the above embodiment may both be regarded as drawing files in a general format obtained after format conversion, and therefore, the cloud coil annotation layer is actually directly loaded into the drawing file corresponding to the construction blueprint in the format, that is, the layer file corresponding to the cloud coil annotation layer is inserted into the drawing file corresponding to the construction blueprint, and a mapping relationship between the cloud coil annotation layer, the change drawing file, and the original drawing file is established. The association relationship between the cloud coil annotation and the drawing is established, so that the three data files can be called according to the association relationship in the following process, for example, in a hanging visual tool of a terminal, the identification of a change drawing is clicked, the cloud coil annotation automatically jumps to a change position, the cloud coil annotation data and the drawing data can be stored in a server, and the cloud coil annotation and the drawing data are automatically loaded when the cloud coil annotation is carried out.

According to the technical scheme provided by the embodiment of the disclosure, the change is articulated to the construction blueprint in a way of cloud coil casting on the line, namely the cloud coil is cast to the construction blueprint middle area with a general format, the incidence relation between the change and the construction blueprint is established, the user can quickly click to skip and check in a visual articulating tool of the terminal, the user can conveniently and quickly position the occurrence position or area of a certain change on the construction blueprint, and the change blueprint corresponding to a certain coil casting on the construction blueprint is quickly positioned.

In some embodiments, the original drawing file is a DWG format file, and the writeback file is a vector diagram file; acquiring the circle note attribute, generating a rewriting file according to the circle note attribute, and executing rewriting operation on the original drawing file by using the rewriting file, wherein the rewriting operation comprises the following steps: the method comprises the steps of obtaining an original drawing file in a DWG format and cloud coil annotation attributes, generating a cloud line vector diagram according to the cloud line attributes, and inserting the cloud line vector diagram into a cloud coil annotation layer file corresponding to the original drawing file in the DWG format by using an API (application programming interface) corresponding to the original drawing file in the DWG format so as to render a cloud coil annotation layer in a drawing of the original drawing file in the DWG format; the cloud coil note attributes comprise the center point, the width, the height, the line type and the color of the cloud line.

Specifically, after the association relationship between the change and the construction blueprint is established, since the drawing inserted into the cloud coil annotation layer is the original drawing file in the general format, in order to implement the cloud coil annotation in the actual original drawing file, the cloud coil annotation information needs to be written back into the original construction blueprint. The purpose of the rewriting is that if the rewriting is not carried out, the cloud coil is displayed on an independent layer, which is equivalent to an independent layer of cloud coil display in the construction blueprint, and only when the cloud coil display layer is superposed on other layers of the construction blueprint, the cloud coil display is overlapped with other layers for viewing, and the final cloud coil display can be seen, so that the cloud coil display can be seen only on the hanging tool. If the construction blueprint is downloaded to the local end and is opened by other graphic engine software, the cloud coil note cannot be seen.

Furthermore, in practical application, because the volume of the drawing file is large, when the transmission of the drawing is realized in each link, the drawing file data can be compressed to obtain binary data, the drawing file of the binary data is used as a transmission object, and the binary drawing file is decompressed after being received by the terminal or the cloud server, so that the transmission efficiency of the drawing data is improved.

According to the technical scheme provided by the embodiment of the disclosure, the change drawing and the construction blueprint are uploaded to a cloud server of the system, and the change drawing and the construction blueprint are converted in a unified format by using a format conversion function to form a drawing file in a unified data format, so that the drawing file can be conveniently released to different graphic engines for display at a later stage; the change of the drawing is hung on the construction blueprint in an online cloud coil injection mode, the incidence relation between the change and the construction blueprint is established, and a user can quickly click, position, skip and check based on an online hanging tool; and finally, reversely writing the cloud coil annotation into the original construction blueprint, and directly displaying the blueprint with the cloud coil annotation information after downloading the construction blueprint. The automatic hooking device can realize automatic hooking between the change drawing and the original drawing without manual hooking operation by means of the change explanation of the paper edition, reduces time consumption of the change hooking operation, is not easy to cause hooking errors, has disordered change corresponding relation, and has the problems of easy loss, damage and the like of the change explanation.
