Description
Technical Field

Background
The load data of each process specialty is important input data for the structural design of the industrial factory building, and the load is applied to the calculation model according to the data when the industrial factory building structure is modeled. Generally, industrial plants have more process specialties, and the number of loads carried by each process speciality is also large, and taking a main plant of a large-scale thermal power plant as an example, the main plant has thousands of pipeline point loads only in one specialty of a steam turbine. When a plant structure is modeled, load values are input one by one according to the positions of the resource-increasing load points so as to be applied to a calculation model. The load point position in the process load lifting is generally marked by relative coordinates, the conventional method is to manually convert the load point position in the load lifting, convert the local coordinates of the load point in the lifting into the overall coordinates of the model, generate nodes at the overall coordinate position, and then manually input the corresponding load value. Because the number of load points is large, a large amount of time and energy are consumed in the modeling process of the plant structure, and meanwhile, the correction by designers is not convenient. In the design process, along with the deep design of the process speciality, the load point investment of the process data at different stages is generally changed, the structure speciality needs to correspondingly change or delete the original load in the calculation model, and the new load data is manually input again according to the new investment. Therefore, the conventional load processing method in the structural modeling has low efficiency, errors easily occur in a manual input mode, when the number of load points is large, a large amount of time is occupied by only inputting the load points, the design period can be directly influenced, and errors easily occur in the manual input mode.

Detailed Description
The present invention will be described in further detail with reference to preferred embodiments and the accompanying drawings. It is to be understood that the following examples are illustrative only and are not intended to limit the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. It should be noted that, for the convenience of description, only some but not all of the matters related to the present invention are shown in the drawings.
Fig. 1 is a flow chart of the load processing method for modeling an industrial plant structure according to an embodiment of the present invention, and the load processing method for modeling an industrial plant structure in this embodiment may be executed by an auxiliary program of CAD software, such as a load derivation program. As shown in fig. 1, the load processing method for modeling the industrial plant structure in this embodiment includes the following steps:
step S110, reading a load contribution CAD file of the industrial factory building, wherein the load contribution CAD file comprises text information of each load point;
in this embodiment, the load-funding CAD file of the industrial plant adopts a typical uniform format, and includes text information of each load point. Fig. 2 shows a typical style of the process pipeline load contribution CAD file, and as can be seen from fig. 2, the load contribution CAD file is mainly composed of load points and text information thereof. Fig. 3 is a schematic diagram of text information in a process pipeline load lifting CAD file, where the text information of a load point is displayed in a closed rectangle of a pline of the load lifting CAD file, the text information of the load point includes local coordinates (i.e., relative coordinates) of the load point and load information, and the load information includes forces and moments of the load point in various directions. Referring to the text information shown in fig. 3, wherein X, Y represents the local coordinates of the load point, Px, Py, and Pz represent the forces of the load point in the x-axis direction, the y-axis direction, and the z-axis direction (the z-axis represents the floor direction), respectively, and the unit is ton (t); mx, My, Mz represent the moment of the load point in the x, y, and z directions, respectively, and are expressed in tons (t "m) herein.
Step S120, determining a relative origin coordinate for carrying out load point coordinate conversion and an industrial factory building floor elevation corresponding to the load contribution CAD file;
the relative origin point coordinate is used for converting the load point coordinate, and the local coordinate of the load point in the load contribution CAD file can be converted into the overall coordinate in the industrial factory building structure model through the determined relative origin point. After the auxiliary program of the CAD software reads the load contribution CAD file of the industrial factory building, a user can manually input the coordinates of the relative origin to the auxiliary program of the CAD software, or manually click the relative origin in the load contribution CAD file, and the auxiliary program of the CAD software can read the coordinates of the relative origin.
The industrial plant floor elevation has the function that the load points in the load-enhancing CAD files can be loaded on corresponding floors in the industrial plant structural model.
Step S130, determining target load points in the load contribution CAD file, respectively identifying text information of each target load point, obtaining local coordinates and load information of each target load point, and converting the local coordinates of each target load point into overall coordinates in the industrial plant structural model according to the relative origin coordinates;
the target load point in this embodiment is the load point to be derived. The user can select the target load point in various ways, for example, the user can freely select the load point in a load contribution CAD file, and the auxiliary program of the CAD software selects the load point in the range of a selection frame as the target load point; or the user manually clicks each load point in the load contribution CAD file to select, and the auxiliary program of the CAD software takes the load point clicked by the user as a target load point.
After the auxiliary program of the CAD software determines the target load points, the text information of each target load point is identified, for example, by a keyword matching method, and the local coordinates and the load information of each target load point can be quickly and accurately identified. And for the local coordinates, converting the determined coordinates relative to the origin point to obtain overall coordinates of the target load point in the industrial plant structural model, wherein the load information can comprise forces and moments of the load point in all directions.
And step S140, importing the overall coordinates and load information of each target load point and the elevation of the industrial factory building into an electronic form.
The spreadsheet in this embodiment may be an Excel file, a WPS file, or the like. The auxiliary program of the CAD software can import the floor elevation (i.e., z coordinate of the load point), the overall coordinate of each target load point, and the load information of each target load point of the industrial plant into the spreadsheet according to a set format, and the spreadsheet can be imported into modeling software such as SAP2000, Midas, and the like, so as to quickly and accurately generate the load point in the structural model of the industrial plant. Therefore, in the load processing method for modeling the industrial factory building structure in the embodiment, the information of the load points in the load contribution CAD file is imported into the spreadsheet, so that the processing efficiency and accuracy of data of the load points during modeling can be effectively improved, the design period is shortened, and when the process load contribution is changed, the change of the industrial factory building structure model can be completed only by exporting the information of the load points to the spreadsheet and importing the information into modeling software to regenerate the load points, which is very convenient to use.
In an alternative embodiment, as shown in fig. 4, after the text information of each target load point is respectively identified, the method further includes:
step S135, changing the display color of the text information of the identified target load point in the load funding CAD file.
When the auxiliary program of the CAD software identifies the text information of the target load point, the display color of the text information of the identified target load point in the load-providing CAD file is changed, so that a user can preliminarily judge whether the text information of the target load point is identified and whether the data is read. For example, the initial display color of the text information of a certain target load point in the load-submitting CAD file is yellow, and after the text information is identified by the auxiliary program of the CAD software, the display color of the text information of the target load point is changed into red, so that the user can intuitively know that the data of the target load point is read.
In an alternative embodiment, still referring to fig. 4, after the text information of each target load point is identified, and before the overall coordinates and load information of each target load point and the elevation of the industrial plant floor are imported into the electronic form, the method further includes:
step S136, displaying the whole coordinate and load information of the identified target load point;
and step S137, receiving an updating instruction input by an operator, and updating the overall coordinates and the load information of the identified target load point according to the updating instruction.
After the auxiliary program of the CAD software identifies the text information of the target load point, the whole coordinate and the load information of the identified target load point are displayed on the display interface of the CAD software, so that a user can visually see the whole coordinate and the load information of the identified target load point, and the user can check whether the identified data has errors. If an error exists, the user can manually modify the overall coordinate and the load information of the load point, namely, the user calculates the correct overall coordinate and load information and inputs the correct overall coordinate and load information as an updating instruction to the auxiliary program of the CAD software, and the auxiliary program of the CAD software responds to the updating instruction input by the user to update the overall coordinate and the load information of the corresponding target load point.
In an alternative embodiment, still referring to fig. 4, after the step of importing the overall coordinates and load information of each target load point and the industrial building floor level into the spreadsheet, the method further comprises:
step S145, performing deduplication processing on the data imported into the spreadsheet.
The deduplication processing in the present embodiment refers to removing duplicate information from stored information to ensure the uniqueness and accuracy of the information. For each identified target load point, the auxiliary program of the CAD software obtains the overall coordinates and the load information of the target load point, and after the overall coordinates and the load information of all the identified target load points are imported into the electronic form, data repetition may exist, so that the data imported into the electronic form are subjected to deduplication processing, each target load point can be guaranteed to be unique, and the accuracy of subsequent modeling is improved.
It should be noted that, for the sake of simplicity, the foregoing method embodiments are described as a series of acts or combinations, but those skilled in the art should understand that the present invention is not limited by the described order of acts, as some steps may be performed in other orders or simultaneously according to the present invention.
In an alternative embodiment, the auxiliary program of the CAD software is a load export program, a file of the program may be copied to a Support folder of the CAD installation directory, after the program is loaded, a dialog box 900 of the load export program is called in some way, as shown in fig. 5, a relative origin coordinate and a z-direction coordinate (i.e., an industrial factory building floor elevation) in the load-providing CAD file are input through the dialog box 900, and a target load point is framed, the auxiliary program of the CAD software identifies a local coordinate and load information of the target load point, automatically converts the local coordinate into an overall coordinate according to the relative origin coordinate, and displays the overall coordinate, the load information, and the industrial factory building floor elevation of the identified target load point at the load data information display box 901. Thereafter, the user clicks the "ok" button on the dialog box 900, and the overall coordinates of the identified target load point, load information, and industrial building floor elevation are automatically imported into the Excel file (which may also be set as other spreadsheets). And for the identified target load point, the display color of the text information corresponding to the load contribution CAD file is changed, so that a user can preliminarily judge whether the data is successfully read, and meanwhile, the data in the Excel file can be subjected to deduplication processing, and the uniqueness and the accuracy of the data are ensured. By importing the information of the load points in the load contribution CAD file into the spreadsheet, the processing efficiency and accuracy of the data of the load points during modeling can be effectively improved, and the time for modeling the industrial plant structure is shortened.
