Description

Technical Field

[0001] This invention belongs to the field of nuclear power technology, specifically relating to a method and apparatus for processing drawing elements. Background Technology

[0002] Nuclear power unit systems are extremely complex. Typically, each unit has up to 100,000 pieces of equipment and involves nearly 300 systems (such as the turbine lubrication system, chilled water system, and steam generator blowdown system). Generally, each unit has about 1,000 system flow diagrams, and each system flow diagram contains dozens to more than 300 pieces of equipment and piping.

[0003] In related technologies, electronic drawings of nuclear power system processes are generally stored in DWG and DXF formats. These drawings often contain numerous non-standard elements, leading to difficulties in searching for or incorrectly identifying equipment and piping. For example, there are hidden elements outside the drawing borders, some elements are on hidden layers, there are combined elements, and a single equipment or piping element is split into multiple elements. Furthermore, the coding of equipment or piping elements is often non-standard. These problems significantly increase the workload and reduce the efficiency of finding equipment and piping in electronic drawings. Summary of the Invention

[0004] To overcome the problems existing in related technologies, a method and apparatus for processing drawing elements are provided.

[0005] According to one aspect of the present disclosure, a method for processing drawing elements is provided, the method comprising:

[0006] Step 100: Identify the canvas size of the electronic drawing to be processed, and establish a Cartesian coordinate system for the canvas of the electronic drawing;

[0007] Step 101: If the electronic drawing contains a hidden layer, delete the hidden layer of the electronic drawing;

[0008] Step 102: After step 101, identify the border of the electronic drawing and delete the graphic elements located outside the border on the electronic drawing;

[0009] Step 103: After step 102, identify the combined graphic elements in the electronic drawing and break up the combined graphic elements.

[0010] Step 104: After step 103, determine multiple groups of graphic elements from each non-border graphic element that contains text. Each group of graphic elements contains multiple graphic elements whose distance from each other meets a preset distance condition.

[0011] Step 105: Concatenate the text of each graphic element in each graphic element block group to obtain a temporary code, and determine whether the temporary code conforms to the preset encoding rules.

[0012] Step 106: If the obtained temporary code is determined to conform to the preset encoding rules, the temporary code is used as the final code to replace the text of one of the primitive blocks in the corresponding primitive block group, and the other primitive blocks in the primitive block group are deleted. If the obtained temporary code is determined to not conform to the preset encoding rules, the temporary code is discarded.

[0013] In one possible implementation, step 102 further includes:

[0014] Step 1020: Obtain the system-preset border deviation distance parameter D;

[0015] Step 1021: Determine the primitive whose text value is equal to any Arabic numeral from 1 to 6;

[0016] Step 1022: Obtain n primitives whose x-coordinate X-value deviation is less than X*D from the primitives whose text value is any Arabic numeral from 1 to 6.

[0017] Step 1023: Group the n primitives according to their X values;

[0018] Step 1024: Determine whether the text values ​​of the graphic elements in each group cover 1-6. If it is determined that the text values ​​of the graphic elements in each group cover 1-6, then the n graphic elements are the left and right borders of the electronic drawing.

[0020] Step 1025: Group the n graphic elements according to their X values, where the first group with smaller X values ​​is the left border and the second group with larger X values ​​is the right border.

[0021] Step 1026: Use the X values ​​of the first group as the coordinates of the left border of the electronic drawing, and use the X values ​​of the second group as the coordinates of the right border of the electronic drawing.

[0022] In one possible implementation, step 102 further includes:

[0023] Step 1027: Obtain the system-preset border deviation distance parameter D;

[0025] Step 1029: Obtain m primitives whose ordinate Y-value deviation is less than Y*D from primitives whose text value is equal to any English letter AF;

[0026] Step 10210: Group the m primitives according to their Y values;

[0027] Step 10211: Determine whether the text value of the graphic element in each group covers AF. If it is determined that the text value of the graphic element in each group covers AF, then the m graphic elements are the top and bottom borders of the electronic drawing.

[0028] In one possible implementation, step 102 further includes:

[0029] Step 10212: Group the m primitives according to their Y values, with the third group having the lower border and the fourth group having the upper border.

[0032] Step 1040: Obtain the system-preset primitive distance parameter E;

[0033] Step 1041: Enumerate all graphic elements in the electronic drawing whose text is arranged in the X direction;

[0034] Step 1042: Traverse the text of each graphic element arranged in the X direction, merge the text of multiple graphic elements whose Y value difference is less than Y*E into temporary codes arranged in the X direction according to the order of the graphic element Y value from large to small, and if the temporary code meets the preset encoding rules, replace the original text of one of the multiple graphic elements with the temporary code, and delete the other graphic elements in the multiple graphic elements.

[0035] In one possible implementation, step 104 further includes:

[0036] Step 1043: Obtain the system-preset primitive distance parameter E;

[0039] In one possible implementation, the method further includes:

[0040] Step 107: After processing each graphic element group according to steps 105 and 106, the annotated electronic drawing is obtained.

[0041] Step 108: Convert the annotated electronic drawing into an image file and display it in the user interface. The image file displayed in the user interface can be dragged, scaled, and annotated.

[0042] In one possible implementation, the method further includes:

[0043] Step 109: Based on the correspondence between each electronic drawing and its final code, perform a fuzzy search on each electronic drawing using the input keywords, and display the search results.

[0044] According to another aspect of the present disclosure, a drawing element processing apparatus is provided, the apparatus comprising:

[0045] The canvas recognition module is used to identify the canvas size of the electronic drawing to be processed and to establish a Cartesian coordinate system for the canvas of the electronic drawing.

[0048] A combination recognition module is used to identify combined graphic elements in the electronic drawing and to break up the combined graphic elements.

[0049] The module determines multiple groups of primitive blocks from each non-bordered primitive block that contains text. Each group of primitive blocks contains multiple primitive blocks whose mutual distance meets a preset distance condition.

[0050] The splicing module is used to splice the text of each graphic element block in each graphic element block group in order to obtain a temporary code, and to determine whether the temporary code conforms to the preset encoding rules.

[0051] The replacement module is used to replace the text of a primitive block in the corresponding primitive block group with the temporary code as the final code if the obtained temporary code is determined to conform to the preset encoding rules, and to delete the other primitive blocks in the primitive block group. If the obtained temporary code is determined to not conform to the preset encoding rules, the temporary code is discarded.

[0052] According to another aspect of the present disclosure, a drawing element processing apparatus is provided, the apparatus comprising:

[0053] processor;

[0054] Memory used to store processor-executable instructions;

[0055] The processor is configured to execute the above-described method.

[0056] According to another aspect of the present disclosure, a non-volatile computer-readable storage medium is provided, on which computer program instructions are stored, which, when executed by a processor, implement the above-described method.

[0057] The beneficial effects of this disclosure are as follows: By processing various types of dirty data, such as combined graphic elements being broken down, a single graphic element being dispersed into multiple graphic elements, hidden graphic elements, and graphic elements outside the boundary, this disclosure achieves graphic element cleaning. Furthermore, by recognizing and extracting the quick text of adjacent graphic elements, it achieves standardized labeling, storage, and location of codes in electronic drawings. This provides nuclear power plant operation and maintenance engineers with fast and accurate graphic element query and labeling functions, greatly facilitating the operation and maintenance work of nuclear power companies and improving work efficiency.

[0058] Compared to existing primitive recognition functions based on OCR technology, the recognition rate of this invention can be increased from approximately 50% to over 98%.

[0104] Figure 2 This is a flowchart illustrating a method for processing graphic elements in a drawing, based on an application example. For example... Figure 2 As shown, the method for processing drawing elements is as follows:

[0105] S100: Predefined list of equipment and piping values. Defines all list types and values ​​that will appear in equipment and piping codes. List types are generally: unit, system, equipment type, plant, room.

[0106] S200: Equipment and Piping Code Predefined. Defines all possible coding formats for equipment and piping in drawings using regular expressions. For example, the complete coding format for equipment is: 1-digit unit code + 3-digit system code + 3-digit serial number code + 2-digit equipment type code, corresponding to the regular expression: [0-9]{1}[A-Za-z]{1}[0-9]{3}[A-Za-z]{1}. If a drawing contains only one equipment element with the unique code "3-digit serial number code + 2-digit equipment type code," a corresponding regular expression must also be defined for this type of element.

[0107] S300: Definition of annotation style for equipment and piping elements. In order to clearly mark the location of the searched elements on the drawings displayed on the drawing search page, it is necessary to define the annotation style, including the annotation color, shape, and line thickness, such as red, line thickness equal to 5px, circle, or yellow, line thickness equal to 3px, 10*50px rectangle;

[0108] S400: Drawing Upload. Enables the uploading of DWG or DXF format drawings individually or in batches. If the CAD drawing file is in DWG format, it will be automatically converted into a text-based DXF format CAD drawing file.

[0109] S500: Identifies the canvas size of the drawing. It reads and parses the text-formatted DXF file according to the official DXF file format, and reads the canvas size of the drawing from the corresponding segments, denoted as X and Y.

[0110] S600: Delete all hidden layers. The program reads and parses the text-formatted DXF file according to the official DXF file format, locates all layers with the display attribute set to hidden, and deletes those layer segments according to the official DXF file format.

[0111] S700: Border recognition. Based on the algorithm prior to this patent, the top, bottom, left, and right borders of the drawing are identified as MaxY, MinY, MinX, and MaxY, respectively.

[0112] S800: Delete elements outside the border. This includes elements with a Y value greater than the top border value MaxY, elements with a Y value less than the bottom border value MinY, elements with an X value greater than the right border value MinX, and elements with a Y value less than the left border value MinX.

[0113] S900: Identifies combined primitive blocks and breaks them up. It reads and parses DXF files in text format according to the official DXF file format, locates all combined primitive blocks, and directly modifies the DXF file to break them up according to the DXF file format specification.

[0114] S1000: Identify devices and pipelines based on pre-configured information. Identify whether each "multi-line text" in the drawing conforms to the coding specifications predefined in step S200. If it conforms to the corresponding graphic element specification, cache the text content, X-axis, and Y-axis of the graphic element in memory.

[0115] S1100: Devices and pipes that identify multiple graphic elements combined into one graphic element. Based on the algorithm of this patent, two "multi-line text" graphic elements that are close in distance along the X-axis or Y-axis are concatenated into one graphic element. The text content, X-axis, and Y-axis of the concatenated graphic element are then cached in memory.

[0116] S1200: Equipment and piping data import. The text content, X-axis, Y-axis, and drawing file information (such as file code, file name, version, etc.) of the cleaned, spliced, and disassembled, compliant equipment and piping elements cached in memory are written into the database.

[0117] S1300: Fuzzy search for equipment and pipeline keywords. Enables fuzzy search functionality based on text content (i.e., keywords related to equipment and pipelines) within graphical elements.

[0118] S1400: Equipment and piping element annotation. A piece of equipment or piping can appear in multiple drawings. After the user selects a drawing on the search results page, a new element is created in the DXF file (i.e., inserted at the position of a relative paragraph in the text file) according to the DXF file format and the annotation style defined in step S300, such as the red circle.

[0119] S1500: Convert CAD drawings to images. Uses background software to convert DXF drawing files into JPG image files;

[0120] S1600: Web-based online drawing preview with zoom and drag-and-drop functionality. Displays JPG drawings containing searched elements (equipment, piping) on ​​a web page, and utilizes built-in web image preview, zoom, and drag-and-drop features to achieve a drawing preview function similar to that in CAD software.

[0121] In one possible implementation, a drawing element processing apparatus is provided, the apparatus comprising:

[0122] The canvas recognition module is used to identify the canvas size of the electronic drawing to be processed and to establish a Cartesian coordinate system for the canvas of the electronic drawing.

[0123] The deletion module is used to delete the hidden layers of the electronic drawing when it is detected that the electronic drawing contains hidden layers;

[0124] A border recognition module is used to recognize the border of the electronic drawing and delete the graphic elements located outside the border on the electronic drawing.

[0125] The combination recognition module is used to identify combined graphic elements in the electronic drawing and break them apart.

[0126] The determination module is used to traverse each primitive block containing multiple texts, and determine primitive block groups from each primitive block containing multiple texts. Each primitive block group contains multiple adjacent primitive blocks.

[0127] The splicing module is used to splice the text of each graphic element block in each graphic element block group in order to obtain a temporary code, and to determine whether the temporary code conforms to the preset encoding rules.

[0128] The replacement module is used to replace the text of a primitive block in the corresponding primitive block group with the temporary code if it is determined that the obtained temporary code conforms to the preset encoding rules, and delete the other primitive blocks in the primitive block group. If it is determined that the obtained temporary code does not conform to the preset encoding rules, the temporary code is discarded.
