Description

Technical Field

[0001] The present invention relates to the technical field of two-dimensional graphics processing, and in particular to a parametric design method for reinforcement of rail transit station beams. Background Art

[0002] In the rail transit industry, parametric design technology based on microservices and cloud computing will be the future transformation direction of rail transit design. In the traditional rail transit industry, designers face many problems that affect design quality and efficiency when designing station beam reinforcement and stirrup samples, mainly including the following four points:

[0003] (1) The beam reinforcement design process is not standardized enough and lacks parametric methods.

[0004] During the beam reinforcement design process, designers need to draw a large number of reinforcement drawings and stirrup drawings. Due to the lack of parametric design methods, when expressing the graphic elements of the main reinforcement, tie bars, waist bars, and stirrups in the beam and adding text dimension annotations, designers need to manually draw them based on structural calculation results and design specifications, or copy and paste previous design results and then adjust them. When the design results need to be adjusted, designers need to manually modify the drawings one by one, which is labor-intensive and prone to errors, resulting in low-quality drawings.

[0005] (2) The parameter interaction of multiple design software relies on manual file transfer and lacks an interface.

[0006] When designing beam reinforcement, designers first need to perform structural calculations using calculation software such as PKPM, Midas, and SAP2000. After adjusting according to design specifications, they obtain the specifications, layout, quantities, and other relevant parameters for the main bars, tie bars, side bars, and stirrups involved in the beam reinforcement. They then manually draw the plan using the design software (AutoCAD). Because the calculation and design software are separate, the reinforcement parameters generated in the calculation sheet cannot be directly imported into the design software for use. Designers must manually draw the beam reinforcement parameters based on the calculation sheet. This results in low drawing efficiency and the risk of operational errors, leading to a high design error rate and a heavy workload for manual review. This ultimately results in high design costs and low quality.

[0007] (3) Due to the inconsistency of design standards and specifications for different projects, the reusability of design results is poor.

[0008] In different rail transit projects, due to the differences in parameters obtained by using different structural calculation software or some special requirements of the project, all reinforcement drawings need to be drawn manually. Existing reinforcement drawing templates cannot be reused. The design workload is large and errors are prone to occur, resulting in low design quality.

[0009] (4) The beam reinforcement design results and process data are not stored in the cloud, making version maintenance and traceability difficult.

[0010] In traditional design processes, both calculation results and drawings generated by computer software are stored electronically on the designer's local computer. When submitted for review, these files are often not fully submitted, hindering project review and archiving. When drawings are repeatedly revised, the resulting version chaos associated with managing project design results across paper documents or electronic files stored on local computers becomes a pressing pain point in design management. Summary of the Invention

[0011] The present invention provides a parametric design method for rail transit station beam reinforcement, resolving the issues of complex software integration, cumbersome operation steps, low standardization of design parameters, and low degree of parameterization in the traditional beam reinforcement drawing process. By managing the various design software, input parameters, and output results required during the design process, a parametric and standardized method for rail transit beam reinforcement is formed. This method significantly improves the efficiency and quality of rail transit beam reinforcement design, effectively reduces design costs, and provides a reference case for parametric design in various rail transit disciplines, with high promotion and application value.

[0012] A parametric design method for reinforcement of rail transit station beams comprises the following steps:

[0013] S100 cloud platform construction

[0014] The cloud platform consists of two parts: a cloud microservice platform and interactive plug-ins for design software. First, the S101 cloud microservice platform is built, followed by the development of interactive plug-ins for design software. This includes secondary development of the S102 structural calculation software and the S103 design software, resulting in plug-ins for structural calculation software and design software.

[0015] S200 Designer Login

[0016] Designers log in to the cloud microservice platform on the design client to log in with their project identity;

[0017] S300 cloud authorization and authentication

[0018] The cloud microservice platform authenticates the designer's identity information. If the authentication fails, the process returns to step S200 where the designer logs in.

[0019] S400 design environment adaptation

[0020] After cloud authorization and authentication, S401 automatically downloads and installs the cloud-based adapter plug-in based on the local installed software: the cloud-based microservice platform automatically determines the current client's design software version and automatically downloads and installs the corresponding design software interactive plug-in, and provides the designer with a list of tool software currently available for design work on the local machine; S402 obtains current project information: the designer can obtain the current design project information, personnel role permissions, and historical design results information from the cloud-based microservice platform; S403 obtains design specifications related to the current project from the cloud-based design specification library: the designer obtains design specifications related to the current project from the cloud-based design specification library as a design reference;

[0021] Parametric Design of Reinforcement for S500 Beams

[0022] S501 Structural calculation: Designers use structural calculation software, such as PKPM, Midas or SAP2000, to perform structural calculations, obtain the structural calculation results of the current project, and adjust them according to the design specifications involved in the current project. After the adjustment is completed, the structural calculation software plug-in is called to automatically extract the geometric parameters required for the parametric design of beam reinforcement, such as length, width, spacing, protective layer thickness, graphic scale and other parameters, and encapsulate the parameters of tie bar level, tie bar diameter, tie bar spacing, stirrup diameter, stirrup spacing, main bar level, number of roots, diameter, number, waist bar level, waist bar diameter, number of waist bars, and spacing from upper and lower steel bars, and upload them to the cloud microservice platform for storage through the structural calculation software plug-in; S502 Generate project beam reinforcement diagram: Designers use the design software plug-in installed in the design software to automatically extract the geometric parameters required for the parametric design of beam reinforcement, such as length, width, spacing, protective layer thickness, graphic scale and other parameters, and encapsulate the parameters of tie bar level, tie bar diameter, tie bar spacing, stirrup diameter, stirrup spacing, main bar level, number of roots, diameter, number, waist bar level, waist bar diameter, number of waist bars, and spacing from upper and lower steel bars, and encapsulate the parameters of main bar level, number of roots, diameter, number, waist bar level, waist bar diameter, number of roots, and spacing from upper and lower steel bars, and upload them to the cloud microservice platform for storage through the structural calculation software plug-in; S502 Generate project beam reinforcement diagram: Designers use the design software plug-in installed in the design software to automatically extract the geometric parameters required for the parametric design of beam reinforcement, such as length, width, spacing, protective layer thickness, graphic scale and other parameters, and encapsulate the parameters of tie bar level, tie bar diameter, tie bar spacing, stirrup diameter, stirrup spacing, main bar level, number of roots, diameter, number, waist bar , through microservices, the parameters required for beam reinforcement design obtained in the structural calculation stage are directly obtained in the cloud microservice platform, and the corresponding beam reinforcement template is selected in the beam reinforcement template library. The design software plug-in can automatically obtain the beam reinforcement input parameters from the cloud microservice platform, and at the same time call the open interface of the design software to automatically generate the project beam reinforcement diagram through algorithm programming, realizing the parametric arrangement of main reinforcement, waist reinforcement, tie reinforcement and stirrup reinforcement, horizontal and vertical surface expression, legend filling and specification name text annotation, and can be manually adjusted; S503 upload design results: after the drawings are generated, all design results are uploaded to the cloud microservice platform through microservices and published, such as beam reinforcement diagram and stirrup detail drawing, waiting for review by the reviewer;

[0023] S600 design results online review

[0024] The reviewer reviews the design results in the cloud microservice platform. If the review fails, the reviewer fills in the review opinion and sends it to the designer, returning to the S500 beam reinforcement parametric design step. The designer modifies and resubmits it for review. After the review passes, the design results are saved in the current project of the cloud microservice platform for future archiving and other retrieval needs, and this design work is completed.

[0025] Furthermore, the cloud-based microservice platform is a beam reinforcement design microservice platform developed through microservices, including a design specification library, a beam reinforcement template library, a functional interface and a big data AI module. The functional interface includes an interface for providing data upload, modification, downloading, review and display for the design software interactive plug-in, as well as an interface for providing information addition, deletion, query and modification for designers, role permissions, design specifications and beam reinforcement templates; the big data AI module establishes a big data model by collecting parameters, project keywords and design specification elements of multiple design projects, and trains the machine through AI through a neural algorithm.

[0026] Furthermore, in step S403 of obtaining design specifications related to the current project through the cloud-based design specification library, designers can call the big data AI module through the cloud-based microservice platform, and use big data and AI functions to intelligently retrieve and obtain design specifications that match the current project as the basis for structural calculations.

[0027] Furthermore, in the structural calculation step S501, designers can call the big data AI module of the cloud microservice platform through the structural calculation software plug-in to perform AI calculations on the calculation results and automatically generate adjustment plan suggestions.

[0028] Furthermore, in the step of generating the project beam reinforcement drawings in S502, the designer can generate design drawings in batches or modify all design drawings in batches by adjusting the beam reinforcement parameters.

[0029] Beneficial effects of the present invention:
