[0002] The petrochemical industry occupies a pivotal position in the national economy, among which chemical equipment is an important part of the petrochemical industry and plays a key role in the production process. The traditional chemical equipment design and drawing process mainly relies on manual drawing, which is not only time-consuming and labor-intensive but also has the risk of errors, and it is difficult to meet the rapidly changing needs of the chemical industry. In addition, during the design process, some parameters often need to be modified. After the parameter is modified, the part related to the parameter on the drawing needs to be modified accordingly, which takes a lot of time and greatly increases the design cycle and labor workload.
[0003] With the rapid development of the petrochemical industry, there is an urgent need for a high-efficiency and high-quality chemical equipment drawing method. This method can not only improve work efficiency and create favorable conditions for drawing, but also has certain variability and fault tolerance. It can easily adjust design parameters and drawing components to generate different chemical equipment drawings, greatly shortening the drawing cycle and ensuring the quality of the drawings. Summary of the invention

In addition, when the drawing is modified, the parts that need to be modified in the drawing can be automatically modified synchronously according to the modified content, thereby reducing the workload when modifying the drawing, and avoiding the occurrence of conflicting parts in the drawing due to the failure of some parts to be modified. The use of this method can greatly reduce the workload of drawing drawing and shorten the drawing drawing cycle.

If it is a new project, you can select a similar type of project in the AutoCAD project archive or create a new project, and directly modify the parameters in it; if it is a completed project, you can open AutoCAD to modify it. After the modification, the corresponding block is set as modified, and then the drawing modification part is automatically started to modify the corresponding parameters of the block set as modified in the drawing database, and find the blocks affected by the parameters in the drawing. Finally, according to the parameter changes, modify the parameters of all blocks and generate new drawing codes. The new drawing code is called again by the AutoCAD secondary development program and generates a new AutoCAD drawing.
[0006] S6: Drawing database is the link between various parts; the structural dimension data, position data and relationship data of each component are stored in the drawing database; each component of the drawing will correspond to a block of the AutoCAD drawing, and the block attributes correspond to the various structural and position parameters; and the drawing modification and the parameter modification of the drawing database are linked together by corresponding to the attribute value of the block in the drawing through the parameters.
[0007] Furthermore, the drawing code generation part in S3 is based on the premise that the structural data and position data of the drawing conform to the graphic logic relationship in order to generate the correct code, otherwise the AutoCAD secondary open program cannot recognize and call the code.
[0008] Furthermore, in the drawing modification part in S5, after a project is completed, the project can be archived, so that the block attribute value can be modified by using the archived project next time to generate a project of the same type.
[0009] Another object of the present invention is to provide a system for automatically generating AutoCAD drawings for chemical equipment based on the method for automatically generating AutoCAD drawings for chemical equipment, the system specifically comprising: Data input module, including input of design data and strength verification calculation data, such as design pressure, design temperature and hydraulic test pressure, etc.; The drawing composition module is connected to the data input module, including determining the components of the drawing, such as drawing sheet, head, cylinder, simplified flange, shell, tube bundle, rear tube box, saddle, etc., and determining the location of each component; clicking on a certain part, such as the head, can set the structural dimensions of the part, the nominal diameter of the head, wall thickness, straight edge length and position, etc.; the structural dimension data, position data and relationship data of each component are stored in the drawing database; each component of the drawing will correspond to a block of the AutoCAD drawing, and the block attributes correspond to the structural and position parameters; The drawing code generation module is connected with the drawing composition module, and generates the code of each part according to the structural data and position data of each drawing component, combined with the national standards, industry standards and enterprise regulations related to chemical drawing; the code can be called by the generation program based on AutoCAD secondary development and automatically generate AutoCAD drawings; The drawing module is connected with the drawing code generation module, opens the AutoCAD software, automatically runs the AutoCAD secondary development program, reads the code generated by the previous drawing code generation part, automatically generates a complete drawing and saves it; In the drawing modification part, if it is a new project, you can select a similar type of project in the AutoCAD project archive or create a new project, and directly modify the parameters in it; if it is a completed project, you can open AutoCAD to modify it. After the modification, the corresponding block can be set as modified, and then the drawing modification part is automatically started to modify the corresponding parameters of the block set as modified in the drawing database, and find the blocks affected by the parameters in the drawing. Finally, according to the parameter changes, modify the parameters of all blocks and generate new drawing codes. The new drawing code is called again by the AutoCAD secondary development program and generates a new AutoCAD drawing.
[0010] The drawing database is connected to the drawing component modules and is the link between the various parts; the structural dimension data, position data and relationship data of each component are stored in the drawing database; each component of the drawing will correspond to a block in the AutoCAD drawing, and the block attributes correspond to the various structural and position parameters; and through the parameters corresponding to the attribute values of the blocks in the drawing, the drawing modification and the parameter modification of the drawing database are linked.
[0011] Another object of the present invention is to provide a computer device, which includes a memory and a processor, wherein the memory stores a computer program, and when the computer program is executed by the processor, the processor executes the steps of the method for automatically generating AutoCAD drawings for chemical equipment.
[0012] Another object of the present invention is to provide a computer-readable storage medium storing a computer program, which, when executed by a processor, enables the processor to execute the steps of the method for automatically generating AutoCAD drawings for chemical equipment.
[0013] Another object of the present invention is to provide an information data processing terminal, wherein the information data processing terminal is used to implement a system for automatically generating AutoCAD drawings of the chemical equipment.
[0014] In combination with the above technical solutions and the technical problems solved, the advantages and positive effects of the technical solutions to be protected by the present invention are as follows: First, (1) The present invention generates codes for each part based on the structural data and position data of each drawing component, combined with national standards, industry standards and enterprise regulations related to chemical drawing, and finally generates a program through AutoCAD secondary development to call the drawing code and automatically generate AutoCAD drawings, thereby realizing automatic drawing of chemical equipment drawings instead of manual drawing. The invention effectively reduces the common errors that occur in manual drawing and significantly improves the efficiency of chemical equipment drawing work, ensuring the quality and accuracy of the drawings.
[0015] (2) When modifying a drawing, the present invention can automatically modify the parts of the drawing that need to be modified according to the modification content, thereby reducing the workload when modifying the drawing and avoiding conflicts in the drawing due to some parts not being modified. The present invention can greatly reduce the workload of drawing and shorten the drawing cycle.
[0016] The present invention not only generates codes for each part according to the structural data and position data of each drawing component, but also combines the national standards, industry standards and enterprise regulations related to chemical drawing, and finally generates a program through AutoCAD secondary development to call the drawing code and automatically generate AutoCAD drawings, thereby realizing the automatic drawing of chemical equipment drawings in the AutoCAD environment. Moreover, when the drawings are modified, the parts that need to be modified in the drawings can be automatically modified synchronously according to the modified content, thereby reducing the workload when modifying the drawings, and avoiding the occurrence of conflicting parts in the drawings due to the fact that some parts are not modified. Thus, the automatic drawing of chemical equipment drawings can be realized instead of manual drawing drawings, and the workload of drawing drawings can be reduced and the drawing drawing cycle can be shortened.
[0017] Second, the expected benefits and commercial value of the technical solution of the present invention after transformation are: Improve enterprise design efficiency: By automatically generating drawings, the design cycle can be greatly shortened.

Promote industrial chain collaboration: Strengthen the collaboration between design and manufacturing, sales, operation and maintenance, and achieve win-win results in the industrial chain. In summary, the present invention has significant economic benefits and commercial value, and is expected to bring rich returns to enterprises. However, the actual benefits still need to be adjusted and evaluated based on market feedback, enterprise operating conditions and other factors.
[0018] The technical solution of the present invention fills the technical gap in the industry at home and abroad: when the drawings are modified, the technical solution of the present invention can automatically modify the parts of the drawings that need to be modified according to the modified content, and can also directly modify the parameters of the archived engineering projects to generate drawings of the same type. It can well solve the problem of complex and time-consuming drawing caused by parameter changes and similar but different drawing components in the chemical equipment design drawings, and realize automatic drawing of chemical equipment drawings instead of manual drawing. At the same time, the drawings are combined with national standards, industry standards and enterprise regulations related to chemical drawing to ensure the standardization of drawings. This provides an innovative technology for promoting the chemical industry to quickly and accurately draw chemical equipment.
[0019] The technical solution of the present invention solves the technical problem that people have been eager to solve but have never been successful: the technical solution of the present invention generates codes for each part according to the structural data and position data of each drawing component, combined with the national standards, industry standards and enterprise regulations related to chemical drawing, and finally generates a program through AutoCAD secondary development to call the drawing code and automatically generate AutoCAD drawings. In addition, when the drawing is modified, the parts that need to be modified in the drawing can be automatically modified synchronously according to the modified content, thus overcoming the difficult problems of large engineering volume and low fault tolerance rate in chemical equipment design and drawing drawing, and breaking the limitation that parameter changes and diversified drawing components limit the drawing drawing efficiency, thereby realizing high-efficiency engineering of chemical equipment design and drawing drawing.
[0020] The technical solution of the present invention overcomes technical bias: it overcomes the arbitrariness of standard implementation, and the automatic generation of drawings can ensure the consistency of design standards. Manual drawing may lead to inconsistent implementation of design standards, thus affecting equipment performance and safety. Designers in different regions may follow different design habits, resulting in differences in technical standards. Overcoming the limitations of manual drawing: traditional methods may lead to uneven quality of drawings due to differences in the personal habits and abilities of designers, and the design may rely too much on personal experience. By overcoming these technical biases, the present invention not only improves the efficiency and accuracy of chemical equipment design, but also helps promote technological progress and development of the entire industry.

At the same time, the same or similar blocks can be called by other projects for the production of other projects.
[0029] An embodiment of the present invention provides a system for automatically generating AutoCAD drawings for chemical equipment based on the method for automatically generating AutoCAD drawings for chemical equipment, and the system specifically includes: Data input module, including input of design data and strength verification calculation data, such as design pressure, design temperature and hydraulic test pressure, etc.; The drawing composition module is connected to the data input module, including determining the components of the drawing, such as drawing sheet, head, cylinder, simplified flange, shell, tube bundle, rear tube box, saddle, etc., and determining the location of each component; clicking on a certain part, such as the head, can set the structural dimensions of the part, the nominal diameter of the head, wall thickness, straight edge length and position, etc.; the structural dimension data, position data and relationship data of each component are stored in the drawing database; each component of the drawing will correspond to a block of the AutoCAD drawing, and the block attributes correspond to the structural and position parameters; The drawing code generation module is connected with the drawing composition module, and generates the code of each part according to the structural data and position data of each drawing component, combined with the national standards, industry standards and enterprise regulations related to chemical drawing; the code can be called by the generation program based on AutoCAD secondary development and automatically generate AutoCAD drawings; The drawing module is connected with the drawing code generation module, opens the AutoCAD software, automatically runs the AutoCAD secondary development program, reads the code generated by the previous drawing code generation part, automatically generates a complete drawing and saves it; Drawing modification part, the drawing modification process is as follows Figure 5As shown, if it is a new project, you can select a similar type of project in the AutoCAD project archive or create a new project, and directly modify the parameters in it; if it is a completed project, you can open AutoCAD to modify it.

[0033] The system realizes the automatic generation of AutoCAD drawings of chemical equipment through the collaborative work of multiple modules. First, the data input module receives design parameters, such as design pressure, design temperature and hydraulic test pressure, and performs strength check and verification by inputting these parameters. These data provide basic data for the generation of subsequent drawings and ensure that they meet the design requirements.

This code can be called by the secondary development program based on AutoCAD to automatically draw drawings that meet the standards. The specific method is that the generated code is passed to the drawing drawing module, which recognizes and calls the drawing code to generate the final drawing.
