Embodiment 1

[0043] In a certain pharmaceutical engineering design project, the process specialty has a total of 95 process flow charts, involving 1,800 pipelines. Using the pipeline number identification and output method of the present invention, the following data are obtained:

[0044] Designer: 1 person.

[0045] Open the AutoCAD program, load the DLL program, read in the process flow chart data, complete the drawing and selection of the frame layer, and the computer automatically completes the identification of the pipeline number in the selected drawing and outputs it to the Excel file. It takes about 20 minutes in total, and There is no manual error or omission, which improves the work efficiency and accuracy of designers.

Embodiment 2

[0047] According to the conditions in Example 1, in a certain medical engineering design project, there are 15 process flow charts in the process specialty, involving 200 pipelines, and the pipeline number identification and output method of the present invention is adopted to obtain the following data:

[0048] Designer: 1 person.

[0049] Open the AutoCAD program, load the DLL program, read in the process flow chart data, complete the drawing and selection of the frame layer, and the computer automatically completes the identification of the pipeline number in the selected drawing and outputs it to the Excel file. It takes about 5 minutes in total, and There is no manual error or omission, which improves the work efficiency and accuracy of designers.

Abstract

The invention relates to a method for identifying and outputting a pipeline number from an AutoCAD format process flow diagram, in particular to a process pipeline table compiling part in medical engineering design, and realizes AutoCAD secondary development and a DLL program through VB.Net. The method comprises the implementation steps: opening AutoCAD, loading the DLL program, reading in processflow diagram file data, newly establishing a diagram layer, drawing a diagram frame rectangular frame, selecting a rectangular frame diagram layer, selecting all drawings needing to be processed, obtaining block table records, filtering layers, obtaining a rectangular frame object set and corner coordinates, traversing all rectangular frames, obtaining a single-row character object set in the corner coordinates of the rectangular frames, traversing all single-row character objects, judging whether a single-row character text is a pipeline number or not, storing the single-row character text in a data list, output the data list to an Excel file, and saving the Excel file. The method is rapid, efficient, convenient to use, high in accuracy and good in reliability, the automation degree andaccuracy of process professional work are improved, and the timeliness of process professional pipeline table compiling work is guaranteed.

Description

technical field [0001] The invention relates to Excel and AutoCAD secondary development technology, in particular to a method for identifying and outputting pipeline numbers in the AutoCAD format process flow chart of VB.Net secondary development. Background technique [0002] In the current pharmaceutical engineering design project, the process design has the characteristics of large number of pipelines, many types, and repeatability, especially the raw material drug project. Pipeline numbering is the basis for crafting the "Pipeline Characteristics List", proposing instrument conditions, and compiling pressure pipeline pipeline tables. In actual projects, the preparation of these materials will have relatively strict requirements on time, and often face the situation of tight time and heavy tasks. [0003] In the prior art CN201911167688.1, a batch process flow card generation method based on AutoCAD and Excel is involved. The method establishes a standard process flow ca...
