Description

Technical Field

[0001] The present invention relates to the technical field of nuclear power engineering design, and in particular to a method and device for generating structured data of engineering drawings. Background Art

[0002] Bulk materials for process pipelines are an important part of the materials of nuclear power plants. They are equivalent to the "blood vessels" of nuclear power plants, connecting thousands of key equipment and are the basis for realizing the functions of nuclear power plant process systems. The data of bulk materials for process pipelines mainly come from the production drawings of process pipelines and supports delivered to the installation unit for construction. The problem of mismatch between material design data and on-site requirements is common in various engineering projects. After analysis, the main reason is that the procurement cycle of bulk materials for nuclear power is long, the publication time of material procurement specifications is much earlier than the completion time of pipeline construction drawing design, and the first edition of procurement specifications is an estimated list, which is quite different from the final actual material requirements. With the deepening of design and the publication of construction drawings, material requirements are constantly changing, resulting in frequent material supplementary procurement orders, long production and delivery cycles, and affecting the progress of on-site installation; if the feedback of material changes is delayed, in order to ensure the progress of the project, the purchase order is placed according to the construction unit's demand report, but due to the lack of accurate design data verification, the construction unit's demand report has a large deviation, resulting in a large amount of material surplus after the project is completed, resulting in material waste. In general, the bulk material data is large and the information is complex, involving a large number of drawings and more drawing design changes. The traditional manual statistics and document funding model will lead to a variety of problems such as non-standard and inaccurate bulk material design data information, many omissions, untimely information flow, low matching rate, etc. Since there is no connection between the data, it cannot be combined with the design links and work processes, there is no effective process control, and the traceability and timeliness are poor.

[0003] The existing patent CN106777808B discloses a network resource generation method based on standardized CAD drawings, and its implementation process is: first design standardized drawings, and parse and present resource data based on the drawings including the completed CAD drawings of the pipeline network, and then generate accurate resource data through comparison, verification, and modification, and finally import it into the comprehensive resource management system for presentation and management. This solution is used to solve the problems of low CAD drawing recognition rate and automatic data import, but does not solve the problems of non-standard data information, low accuracy, many missing items, untimely information flow, and poor traceability when processing bulk material design data information through manual statistics and document funding models in the prior art.

[0004] The existing patent CN109740226A discloses a distribution network drawing system that is efficient and incorporates verification and assessment rules. The system includes a terminal management module, a data management module, a login management module, a verification and assessment module, and a drawing drawing management module, wherein the terminal management module is connected to the data management module, the login management module, and the drawing drawing management module, respectively, and the login management module is connected to the verification and assessment module. This solution is used to solve the problems in the drawing drawing process, but does not solve the problems in the prior art of processing bulk material design data information through manual statistics and letter funding mode, such as non-standard data information, low accuracy, many missing items, untimely information flow, and poor traceability.

[0005] In summary, the above two existing patents have not solved the problems in the prior art of processing bulk material design data information through manual statistics and letter funding models, such as non-standard data information, low accuracy, many missing items, untimely information flow, and poor traceability.

[0087] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0088] The present invention is further described in detail below in conjunction with specific embodiments. These embodiments should not be construed as limiting the scope of protection claimed by the present invention.

[0089] Example

[0090] In order to solve the problems of non-standardized data information, low accuracy, many missing items, untimely information flow and poor traceability in the prior art, the present invention proposes a method and device for generating structured data of engineering drawings. By analyzing the information in the process pipeline ISO drawing and the pipeline support manufacturing drawing, the data information in the process pipeline and support drawings is treated as structured data as a data unit, so that the material item information is standardized and normalized, which is convenient for computer application management.

[0091] To achieve the above object, the present invention proposes a method for generating structured data of an engineering drawing.

[0092] like Figure 1 A flow chart of a method for generating structured data of an engineering drawing according to an embodiment of the present invention is shown in FIG. 1 , and the flow chart includes the following steps:

[0093] S1, obtaining the code of the engineering drawing, and determining the drawing type of the engineering drawing according to the code.

[0094] In this embodiment, CAD engineering drawings are taken as an example. After reading the engineering drawings, the frame position of the engineering drawings is located, and the code of the engineering drawings is obtained at the frame position. The code includes an internal code and an external code. When the external code contains a first preset string and the internal code contains a second preset string, the drawing type of the engineering drawing is determined to be a process pipeline ISO drawing. In this embodiment, the first preset string is 15SD, and the second preset string is BZS03. When the external code contains a third preset string and the internal code contains a fourth preset string, the drawing type of the engineering drawing is determined to be a pipeline support and hanger production drawing. The third preset string is 16SD, and the fourth preset string is BZS02.

[0095] S2, determining the data structure template corresponding to the drawing type.

[0096] After determining the drawing type of the engineering drawing, match and call the corresponding data structure template. Specifically, when the drawing type is a process pipeline ISO drawing, the data structure template corresponding to the process pipeline ISO drawing includes drawing information, item information, installation information and system pipeline design information, such as Figure 2 The data structure template of the process pipeline material corresponding to the process pipeline ISO drawing is shown. When the drawing type is a pipeline support and hanger production drawing, the data structure template corresponding to the pipeline support and hanger production drawing includes drawing information, item information, installation information and bracket design information, such as Figure 3 The pipe support and hanger material data structure template corresponding to the pipe support and hanger production drawing is shown.

[0097] S3, parse the engineering drawings and obtain the corresponding drawing data.

[0098] When the drawing type of the engineering drawing is a process pipeline ISO drawing, the process pipeline ISO drawing is identified and parsed. By locking and identifying the fixed text feature values, the five areas of the process pipeline ISO drawing are located, namely the drawing title bar information, material detail column information, weld list and installation location information, system pipeline attribute information and main drawing design information. Specifically, the drawing title bar information of the process piping ISO drawing includes basic drawing parameter information such as project number, internal and external drawing codes, version, drawing type, release time, drawing name, and drawing size, which can be used to trace the source and time schedule of material item requirements; the material detail column information of the process piping ISO drawing includes serial number, name and material (i.e., specific specification parameters of material items), nominal diameter, item code, quantity, unit weight, and total weight; the weld list and installation location information includes factory weld number, on-site weld number, unit number, installation area, and room number, which can be used for positioning statistical analysis; system pipeline attribute information includes medium, pipeline grade, design temperature, test pressure, insulation thickness, specification grade, cleanliness, etc.; the main drawing design information includes pipeline number, connection information, support bracket number, pipe section number, pipe section length, etc.

[0099] When the drawing type of the engineering drawing is the pipe support and hanger production drawing, the pipe support and hanger production drawing is identified and parsed. The identification area corresponding to the pipe support and hanger production drawing includes four parts, namely the drawing title bar information, material detail column information, pipe support and hanger attribute information and main drawing design information. The drawing title bar information includes the project number, internal and external drawing code, version, drawing type, release time, drawing name, drawing width and other basic drawing parameter information, which can be used to trace the source and time progress of material item requirements. The pipe support and hanger drawing material detail column information includes serial number, name and code, quantity, material, unit weight, total weight, remarks, item code; the support and hanger attribute information includes the three-dimensional drawing number of the pipeline where the support and hanger is located, the drawing number of the bracket position drawing where the support and hanger is located, the specification level, and the bracket function; the main drawing design information includes the support and hanger root wall number, the relevant wall number, the pipeline number, the location elevation, the total frame number (if any), and the embedded plate number.

[0100] After parsing the engineering drawings and obtaining the corresponding drawing data, the drawing data is stored in the data cache layer. Among them, the name and material, name and code information in the material detail column information are divided into independent information according to each attribute after parsing and stored in the data cache layer.

[0101] S4, using the database file corresponding to the drawing type in the material database to verify the drawing data.

[0102] Similar to the data structure template, when verifying the drawing data, different drawing types correspond to different database files. Figure 4 As shown, this step includes the following three sub-steps:

[0103] S401, identifying corresponding material items according to item codes in drawing data.

[0104] S402, searching for standard material items and standard attribute information corresponding to the same item code in a database file corresponding to the drawing type, and verifying the attribute information of the material items in the drawing data one by one according to the standard attribute information.

[0105] Specifically, the attributes of pipeline material items include material name, wall thickness (pressure level), manufacturing form, connection form, specification standard, material, nominal diameter, item code, specification level, quality assurance level, unit weight, etc.; the attributes of pipeline support and hanger material items include material name and model, material, item code, unit weight, specification level, quality assurance level, etc. Among them, the specification level and quality assurance level of material items are not reflected in the drawings. For example, the manufacturing form includes seamless, welding and forging, etc.; the connection form includes butt welding, socket welding and threaded connection, etc.; the wall thickness unit includes pressure level, pipe schedule (SCH), millimeter, etc.; the specification standards include B36.10M, B36.19M, B16.5, B16.9, B16.11, etc.

[0106] S403, if the attribute information of the material item is inconsistent with the standard attribute information, the inconsistent attribute information in the material item is marked and the correct attribute information is prompted.

[0107] When the attribute information of a material item is inconsistent with the standard attribute information, it indicates that the drawing data of the current engineering drawing has erroneous attributes. In this step, the inconsistent attribute information is marked to prompt the user of the erroneous attributes of the material and to modify it.

[0108] In another embodiment of the present invention, the drawing data is verified by using a database file corresponding to the drawing type in the material database, and the specification level and quality assurance level of the material items in the drawing data are filled in to improve the drawing data. The specific process is as follows: S404, according to the item code in the drawing data, the standard item specification level and quality assurance level corresponding to the same item code are searched in the standard attribute information;

[0109] S405, filling the standard item specification level and quality assurance level into the corresponding position of the material item in the drawing data.

[0110] In another embodiment of the present invention, the drawing data is verified by using a database file corresponding to the drawing type in the material database, and the method further includes: S406, performing a text format check on the material detail column, the text format check including whether the material detail column serial number is continuous, whether the serial number is repeated, whether the representation symbol is wrong, and whether the data format is standardized. If the material detail column has one or more of the following non-standard formats, such as non-continuous serial number, repeated serial number, wrong representation symbol, and non-standard data format, the text format check fails, the non-standard text information is marked, and the reason for the non-standard text format is prompted.

[0111] In another embodiment of the present invention, further, the drawing data is verified by using a database file corresponding to the drawing type in the material database, and it also includes verifying whether there are missing items in the drawing data. The verification process includes: S407, judging whether the drawing data contains the item codes of flange materials, gasket materials and fastener materials at the same time; S408, if the drawing data contains the item codes of flange materials, gasket materials and fastener materials at the same time, it is determined that the flange set design is complete; S409, if the drawing data lacks the item codes of any one or more materials among flange materials, gasket materials and fastener materials, then the missing material items in the drawing data are prompted.

[0112] S5, generating and outputting structured data of the verified drawing data according to the corresponding data structure template.

[0113] like Figure 5 As shown, in another embodiment of the present invention, after verifying the drawing data, before generating and outputting the structured data of the verified drawing data, the material quantity units in the drawing data are also converted to unify the statistical basis for material data analysis, so as to facilitate the statistical processing and application of material data. Specifically, the following steps are included:

[0114] S6, determine the material type based on the item code in the drawing data.

[0115] S7, determine the material size based on the material details list information.

[0116] S8, based on the material type and material size, using a preset material quantity unit conversion algorithm, converting the material quantity unit in the drawing data into a standard unit.

[0117] Table 1 shows the material types corresponding to the two drawing types, as well as the judgment rules, calculation types, statistical units, quantity calculation formulas, drawing quantities, and related material detail samples and statistical quantity samples corresponding to the material types. For the pipeline ISO drawing corresponding to serial number 1, when the item coding format in its drawing data is FBS00***, it can be determined that the corresponding material type is screw; determine the material size based on the name and material column in its material detail column information, and identify the field L. From the example corresponding to serial number 1, it can be seen that the item code is FBS00138, and the corresponding material type is screw, and the length L is 150. The quantity calculation formula corresponding to the screw is (L×10 -3 )×number of drawings. Since the number of drawings in this example is 16, the number of materials can be converted to (150×10 -3)×16=2.4m. The judgment rules and calculation types for the materials corresponding to serial numbers 2 to 4 are similar to those for serial number 1, so the corresponding judgment and calculation process will not be repeated here. For the steel plate material type of the support and hanger production drawing of serial number 5, the corresponding calculation type is area calculation. First, identify the item code in the drawing data. If the item code format is: FWB00***, then the corresponding material type is steel plate (sealing plate, blocking plate, partition, reinforcement plate). Then, according to the name in the drawing data and the following format of the material column: number (length) × number (width) × number (thickness) or Ф number (diameter), e = number (thickness), determine the corresponding material size. For example, the example corresponding to serial number 5 is FWB00256 partition, Ф122, e=10, from which it can be obtained that the diameter of the material is 122 and the thickness is 10. According to the corresponding calculation formula π×(diameter / 2×10 -3 )×(diameter / 2×10 -3 )×number of drawings, the corresponding number of materials can be converted to π×(122 / 2×10 -3 )×(122 / 2×10 -3 )×1=0.01㎡.
