Description

Technical Field

[0001] This invention relates to the field of CAD drawing recognition technology, specifically to an intelligent design review system for power transmission and transformation projects based on CAD drawing element recognition technology. Background Technology

[0002] Currently, cost estimators in the power transmission and transformation engineering field frequently deal with three types of drawings: CAD design drawings (or CAD original drawings, CAD base drawings), 2D engineering modeling drawings, and 3D display drawings. The widely used BIM software is Autodesk Revit. When designing and exporting drawings using Revit, DWG files can be directly exported. However, the layers, text styles, line types, and annotation styles in the exported DWG drawings often fail to meet the standards for construction drawings. To ensure that the BIM design drawings meet the standards for construction drawings, extensive modifications to the CAD drawings exported from Revit are necessary. However, during the engineering design phase, drawings often need to be modified or changed. These modified or changed drawings then need to be re-exported from Revit, and further modifications to the exported CAD drawings are required to meet the standards for construction drawings. For typical engineering projects, which involve multiple disciplines and a massive number of drawings, modifying each layer, text style, line type, and annotation style would be extremely time-consuming and labor-intensive, slowing down the project and impacting the project schedule. Therefore, this invention provides a system for the automatic recognition and management of CAD drawings, facilitating the automatic identification and review of CAD drawings. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides an intelligent design review system for power transmission and transformation projects based on CAD drawing element recognition technology, which solves the problem of automatic recognition and management of CAD drawings.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an intelligent design review system for power transmission and transformation projects based on CAD drawing element recognition technology, comprising a cloud server module. The cloud server module includes an upload module, an automatic detection module, an automatic recognition module, a database module, and a comparison and analysis module. The upload module is connected to the automatic detection module, the automatic detection module is connected to the automatic recognition module, the automatic recognition module is connected to the database module, and the output end of the database module is electrically connected to the comparison and analysis module.

The data import unit is connected to the drawing import unit, the drawing import unit is connected to the drawing storage unit, and the drawing storage unit is connected to the proofreading unit. The upload module is used to upload and store data and drawings.

The scanning unit is connected to the previous year's drawing import unit, and the output terminal of the previous year's drawing import unit is electrically connected to the input terminal of the document and drawing detection unit. The automatic detection module is used for importing and detecting documents and data.

[0008] Preferably, the automatic identification module includes an input data unit, a data classification unit, a data storage unit, and a data import unit. The input data unit is connected to the data classification unit, the data classification unit is connected to the data storage unit, and the data storage unit is connected to the data import unit.

[0009] Preferably, the database module includes an import unit, an import unit, and an upload unit. The import units are connected to each other and the import units are connected to the upload unit. The database module is used to import and upload data.

[0010] Preferably, the comparison and analysis module includes an engineering cost data unit, an engineering cost data upload unit, an engineering equipment and materials comparison unit, and an early warning unit. The engineering cost data unit is connected to the engineering cost data upload unit, the engineering cost data upload unit is connected to the engineering equipment and materials, and the engineering equipment and materials are connected to the early warning unit. The comparison and analysis module is used to compare and identify drawings and engineering costs.

[0011] Preferably, the automatic recognition module includes a startup program unit, an image acquisition unit, an image scanning unit, and an image edge analysis unit. The startup program unit is connected to the image acquisition unit, the image acquisition unit is connected to the image scanning unit, and the image scanning unit is connected to the image edge analysis unit. The automatic recognition module is used to recognize and extract images from within the CAD software.

[0012] Working Principle: When using the intelligent design review system for power transmission and transformation projects based on CAD drawing element recognition technology, the system first uploads the CAD drawings to be recognized to the data import unit via the cloud server module. The data and drawings are then stored in the drawing storage unit for easy access and to prevent data and drawing loss during operation. The verification unit compares the uploaded data and images, analyzes the data and drawings, and further identifies the overlap between them. The automatic repair unit automatically repairs problems in the drawings, reducing issues such as misaligned lines and fills. The automatic detection module scans the drawings and analyzes the scanned data with previous years' drawings. The document and drawing detection unit further checks the overlap between the drawings and documents, reducing the number of times construction personnel need to modify the drawings. The automatic recognition module automatically recognizes the data and drawings, inputs the data, classifies the data and drawings through the data classification unit, and saves it in real time through the data storage unit. To ensure the preservation of drawings and data, the system employs several mechanisms. First, categorized data is imported into the database module. The database module then imports the categorized data and drawings into the database module, saving them according to their respective formats. The export module then uploads the organized data and drawings to the cloud server module for storage, thus creating a categorized storage system for data and drawings. The comparison and analysis module analyzes and compares CAD drawings with the required materials and equipment. The engineering cost data unit extracts the data and uploads it through the engineering cost data upload unit. The uploaded data is compared with the data within the engineering cost data unit. The engineering equipment and materials comparison unit analyzes the material prices of the required equipment. If the price exceeds a certain percentage, the abnormal data is marked, and the marked abnormal cost data is output. An early warning unit provides a warning. During the automatic recognition of CAD drawings, the system automatically starts the CAD program and captures the drawings through the image acquisition unit. The image edge analysis unit then performs automatic recognition and extraction of CAD drawings.
