Background Art

[0002] Currently, process system design requires the creation of a process flow diagram (PFD). For example, the design of process piping within a process system requires the creation of a P&ID (Piping and Instrumentation Diagram). Traditionally, designers draw upon the process system, referencing similar projects from previous projects. Reusable drawings are reused, and modifications are made if they are not. This approach has the disadvantage that the speed and quality of design depend on the designer's experience and knowledge. This approach is subject to significant human error, resulting in low efficiency and non-standardization.

[0017] Unless otherwise explicitly stated, throughout the specification and claims, the term "comprise" or variations such as "comprises" or "comprising" will be understood to imply the inclusion of a stated element or group of elements but not the exclusion of any other element or group of elements.

[0018] The technical solutions of the present invention are described below by means of specific embodiments. It should be understood that one or more steps mentioned in the present invention do not exclude the presence of other methods and steps before and after the combination step, or other methods and steps may be inserted between these explicitly mentioned steps. It should also be understood that these examples are only used to illustrate the present invention and are not used to limit the scope of the present invention. Unless otherwise specified, the numbering of each method step is only for the purpose of identifying each method step, and does not limit the order of arrangement of each method or the scope of implementation of the present invention. Changes or adjustments in their relative relationships can also be regarded as the scope of implementation of the present invention without substantial changes in the technical content.

[0019] The sources of the raw materials and instruments used in the examples are not particularly limited and can be purchased from the market or prepared according to conventional methods known to those skilled in the art.

[0020] P&ID diagrams are primarily used to demonstrate the connections and control logic between piping, instruments, valves, and other equipment in a process flow. Short for process piping and instrumentation diagrams, they are essential drawings for project design and construction.

[0021] Currently, there are two basic ways to generate P&ID drawings. One is to refer to previous similar projects, use existing engineering drawings, and modify the details. The other is to determine the pipeline diameter and details based on process equipment parameters and engineering experience, and redraw the drawings.

[0022] Current design methods suffer from low efficiency and a heavy reliance on the designer's experience and expertise for detailed control. Since process equipment parameters are the primary factor, piping parameters must adapt accordingly. Therefore, piping P&IDs are often redesigned based on these parameters, resulting in low P&ID design efficiency and limited engineering reusability. Therefore, a method is needed to analyze accumulated project data and process parameters based on requirements and projects, autonomously generating the required P&ID diagrams through simple calculations and commands.

[0023] In view of the defects in the prior art, the present invention provides a method for drawing a process system flow chart. Figure 1 A process 100 of an embodiment of a method for drawing a process system flow chart is shown. The method for drawing a process system flow chart includes the following steps:

[0024] Step 101: Obtain drawing requirement information of a process system flow chart.

[0025] In this embodiment, the process system flow chart is a graphical tool for describing materials, energy, equipment and operation steps in an industrial production process. The process system flow chart includes: a scheme flow chart, a process flow chart and a P&ID diagram.

[0026] In this embodiment, the drawing requirement information is the user's requirement for the process system flow chart. The drawing requirement information includes: the equipment name and specifications in the process system flow chart, etc. For example, the drawing requirement information includes: drawing a drawing of a compressed air station. The compressed air station is two 100Nm3 compressed air stations. The target process system flow chart can be obtained by processing the drawing requirement information through the process system flow chart drawing method. The target process system flow chart is the process system flow chart required by the user.

[0027] Step 102: Determine the target category and the initial subcategory under the target category based on the drawing requirement information.

[0028] In this embodiment, the initial subcategories are determined solely based on the drawing requirements information. Compared to the target subcategories ultimately determined based on the user-entered parameter information, the initial subcategories are less accurate. The process system flow chart drawing method provided in this disclosure includes an equipment parameter table within the diagram design template library. The user-entered parameter information in the equipment parameter table allows optimization of the initial subcategories, providing a reliable method for obtaining the target process system flow chart.

[0029] In this embodiment, the drawing requirement information and the information of the pre-built drawing design template library can be sent to the multimodal large model together. The multimodal large model analyzes the drawing requirement information and determines the target category and the initial subcategory under the target category corresponding to the drawing requirement information.

[0030] Optionally, the above step 102 also includes: extracting the device names of all devices in the drawing requirement information; clustering the device names of all devices and determining the cluster type; matching the cluster type with the major category in the pre-built graphic design template library, and if the cluster type successfully matches the major category in the graphic design template library, the major category is used as the target major category; continuing to match the device names of all devices with the subcategories under the target major category, and if the number of device names matching the subcategory is the largest, the subcategory is used as the initial subcategory under the target major category.

[0031] Optionally, based on the drawing requirement information, determining the target category and the initial subcategory under the target category includes: extracting keywords from the drawing requirement information, and matching the extracted keywords with the preset category and the keywords under the category, corresponding to the extracted keywords matching the preset category or the keywords under the category, determining that the target category is the preset category, or the initial subcategory is the subcategory under the preset category.

[0032] Step 103 : Based on the target major category and the initial minor category, a device parameter table is extracted from a pre-built graphic design template library and sent.

[0033] In this embodiment, the graphic design template library is a template library specially designed for generating process system flow charts. The graphic design template library includes: major categories, minor categories, and corresponding equipment parameter tables and process system flow chart templates under the minor categories. Among them, the process system flow chart template is a general framework composed of graphic symbols, text annotations and connecting lines, which is used to intuitively display the complete process logic from raw material input to finished product output, including equipment, pipelines, control nodes and operation steps, and the equipment parameter table is a table that represents or calculates the parameters of the equipment in the process system flow chart template. The equipment parameter table may include: equipment name, equipment type, equipment parameters, and parameter values ​​of equipment parameters. Among them, equipment parameters are parameters of equipment, and parameter values ​​of equipment parameters are specific values ​​of equipment parameters. Parameter values ​​of equipment parameters are also called equipment parameter values. It should be noted that the parameter values ​​of some equipment parameters in the equipment parameter table can be fixed values, and the parameter values ​​of some equipment parameters can be blank. After the equipment parameter table is sent to the user's client, the user can fill in the parameter values ​​in the equipment parameter table on the client to represent the specific values ​​of the equipment parameters of the equipment. The device parameter table can also include calculated parameters for a specific device and their values. Calculated parameters are intermediate parameters for a specific device. By calculating their values, you can obtain the device parameter's value. For example, in a P&ID diagram, the device parameter is the pipe diameter, and the calculated parameter is the medium flow rate. Users can enter the medium flow rate value and, by substituting the medium flow rate value into the device parameter calculation formula, obtain the pipe diameter, i.e., the device parameter's value.

[0034] In this embodiment, the above-mentioned step 102 includes: determining the devices to be drawn that belong to the target major category and the initial minor category, comparing the similarity between the devices to be drawn and the devices in the device parameter table in the drawing design template library, and in response to there being only one device parameter table whose similarity to the device to be drawn is greater than a similarity threshold, extracting the device parameter table and sending the device parameter table to the user; in response to there being multiple device parameter tables whose similarity to the device to be drawn is greater than a similarity threshold, extracting the number of devices to be drawn in the drawing requirement information, matching the number with the parameter values ​​of the device parameters representing the number of devices in the multiple device parameter tables, and in response to the number successfully matching the parameter value representing the number of devices in one device parameter table, extracting the device parameter table and sending the device parameter table to the user.

[0035] Step 104: Receive parameter information after the user fills in the device parameter table.

[0036] In this embodiment, parameter information is the information obtained after the user completes the equipment parameter table. The parameter information may include: the original information in the equipment parameter table, such as the equipment type and equipment parameters; and the new information filled in by the user. The new information is the value corresponding to the original information, such as the new information after the parameter value corresponding to the equipment parameter is filled in, or the new information is the type after the parameter corresponding to the equipment type is selected. It should be noted that the parameter information may include parameter values ​​of equipment parameters that cannot be directly determined by the drawing requirement information. Through the parameter information, the execution entity on which the process system flow chart drawing method runs can directly determine the specifications of specific equipment in the process system flow chart template.

[0037] In this embodiment, the content in the parameter information can constitute a new device parameter table, and the fields of the new device parameter table can be the same as the fields of the device parameter table. With respect to the values ​​of the fields of the device parameter table, the new device parameter table is different from the device parameter table.

[0038] Step 105: Determine the target subcategory and the device information under the target subcategory based on the parameter information.

[0039] In this embodiment, the target subcategory and the initial subcategory are both located under the target major category. The equipment information is the information of the equipment in the subcategory. The equipment information corresponding to the target subcategory is different from the equipment information corresponding to the initial subcategory. The target subcategory is a category determined by parameter information. At this time, the process system flow chart template corresponding to the target subcategory is different from the process system flow chart template of the initial subcategory. The target subcategory can accurately reflect the drawing requirement information and the parameter information filled in by the user.

[0040] In this embodiment, the device parameter table includes multiple device fields and their corresponding values. The parameter values ​​can be new device fields and their corresponding values, relative to the original device parameter table filled in by the user. The new device fields correspond to the new device. Using this parameter information, the initial subclass can be overturned to obtain the target subclass. This target subclass can then accurately support the type of drawing requirement information.

[0041] The above step 105 includes: determining a new device name based on parameter information; querying the category table in the graphic design template library based on the new device name to obtain a target subcategory; querying and obtaining device information based on the target subcategory, wherein the device information represents information about the new device.

[0042] Step 106 : extracting a process system flow chart template from a diagram design template library based on the target major category, target minor category, and equipment information.

[0043] In this embodiment, the target major category, target minor category and equipment information are matched with the information in each process system flow chart template in the diagram equipment template library. In response to the target major category, target minor category and equipment information all being successfully matched with a process system flow chart template, the process system flow chart template is extracted.

[0044] In this embodiment, each process system flow chart template in the diagram design template library corresponds to an equipment parameter table, and each equipment parameter table records the information of the equipment in the corresponding process system flow chart template. The above step 104 can also include: matching the target category, target subcategory and equipment information with the information in the equipment parameter table in the diagram design template library. In response to the successful matching of the target category, target subcategory and equipment information with the equipment parameter table in a diagram design template library, extracting the process system flow chart template of the equipment parameter table.

[0045] Step 107: Determine the equipment parameter value of each equipment in the process system flow chart template based on the parameter information.

[0046] In this embodiment, the equipment parameter values ​​are parameter values ​​of equipment parameters. When the target process system flow chart is not determined, the equipment parameter values ​​of some equipment in the process system flow chart template need to be calculated, and the equipment for which the equipment parameter values ​​need to be calculated is a specific equipment. For example, if the target process system flow chart is a P&ID diagram, generally, when designing the P&ID diagram, it is necessary to calculate the pipe diameter. For this purpose, the specific equipment in the P&ID diagram is a pipe.

[0047] In this embodiment, the parameter information includes: calculation parameters and parameter values ​​of the calculation parameters. The calculation parameters are intermediate parameters of a specific device. By calculating the parameter values ​​of the calculation parameters, the parameter values ​​of the device parameters can be obtained. Step 105 includes: determining the device parameters of the specific device in the process system flow chart template; determining the calculation parameters corresponding to the specific device based on a preset parameter calculation formula; extracting the parameter values ​​of the calculation parameters from the parameter information; and substituting the parameter values ​​of the calculation parameters into the parameter calculation formula to obtain the device parameter values ​​of the device parameters of the specific device. The parameter calculation formula is a formula that characterizes the relationship between the calculation parameters and the device parameters of the specific device.

[0048] In this embodiment, the device parameter value of each device may be a fixed value or a range of values ​​within a certain range. The specific value of the device parameter value may be determined based on the situation of the specific device.

[0049] Step 108: Based on the equipment parameter values, update the process system flow chart template to obtain the target process system flow chart.

[0050] In this embodiment, each device in the process system flow chart template is drawn using the device parameter value, and the value of each device in the process system flow chart template can be fixed, thereby obtaining a fixed target process system flow chart.

[0051] In this embodiment, the target process system flow chart is a drawing obtained after the process system flow chart is drawn according to the user's drawing requirements and parameter information. Compared with the drawings designed completely manually, the target process system flow chart is a drawing established based on the principles of artificial intelligence, which saves the time and cycle of drawing design and improves the efficiency of drawing design.

[0052] The process system flow chart drawing method provided by the present invention first determines the target major category and initial minor category through drawing requirement information; extracts the equipment parameter table through the target major category and initial minor category, determines the target minor category through the user's filling in the equipment parameter table, and then extracts the process system flow chart template through the target major category and target minor category, thereby improving the reliability of the process system flow chart template extraction; through the accumulation of existing process system flow charts, a drawing design template library is generated, which can be screened, called and data analyzed in the huge drawing design template library according to the input drawing requirement information, and the process system flow chart template and equipment parameter table can be quickly found. Drawing parameter calculation is performed based on the input parameter information, and the process system flow chart template in the drawing design template library is intelligently updated to form a reasonable target process system flow chart. Through the system's built-in calculation and comparison library, the accuracy of the process system flow chart design is greatly improved, the time and cycle of the process system flow chart design are saved, the design efficiency is improved, and the dependence on the work experience of the designer is eliminated.

[0053] In some optional implementations of the present disclosure, the above-mentioned determination of the target category and the initial subcategory under the target category based on the drawing requirement information includes: identifying the drawing type and drawing name, drawing device keywords and the number of devices in the drawing requirement information; based on the drawing type and drawing name, determining the target category in the pre-built drawing design template library; based on the drawing device keywords and the number of devices, selecting the initial subcategory from the table corresponding to the subcategory under the target category.

[0054] In this optional implementation, the pre-built diagram design template library is a pre-built database, and the data in the database includes: multiple major categories, subcategories under each major category, tables corresponding to each subcategory, and process system flow chart templates, where the tables corresponding to the subcategories can be tables for recording different equipment parameters in the process system flow chart template.

[0055] In this optional implementation, the type keywords and name keywords in the drawing requirement information can be analyzed through a natural language model to determine the drawing type and drawing name in the drawing requirement information. For example, the drawing requirement includes "drawing a compressed air station drawing of the P&ID type", the drawing type is the P&ID type, and the drawing name is the compressed air station drawing. Through the drawing type and drawing name, it can be determined that the major category is the compressed air station drawing in the P&ID. Specifically, the drawing type and drawing name are matched with the major categories in the drawing design template library respectively. In response to a successful match, it is determined that the drawing type and drawing name belong to the major category, and the major category is the target major category.

[0056] In this optional implementation, the device name and quantity in the drawing requirement information can be analyzed through a natural language model to determine the device keywords and device quantity in the drawing requirement information. After determining the target category, the device keywords and device quantity can be matched with the fields in the tables of different subcategories under the target category at the same time. In response to the successful simultaneous match of the device keywords and device quantity, the subcategory is used as the initial subcategory.

[0057] In this optional implementation, after determining the initial subcategory, the initial table can be used as a device parameter table, and when sending the device parameter table, the device parameter table can be sent to the user's terminal, so that the user can fill in the device parameter table at the terminal and obtain parameter information.

[0058] The method for extracting and sending the device parameter table provided by the present invention identifies the drawing type and drawing name, drawing device keywords and the number of devices in the drawing requirement information; based on the drawing type and drawing name, determines the target category in the pre-built drawing design template library; based on the drawing device keywords and the number of devices, selects the initial subcategory from the table corresponding to the subcategory under the target category, providing a reliable implementation method for obtaining the target category and the initial subcategory.

[0059] In some optional implementations of the present disclosure, the above-mentioned extraction of process system flow chart templates from the diagram design template library based on target major categories, target minor categories and equipment information includes: determining the main equipment based on the target major categories, target minor categories and equipment information; matching the main equipment with the equipment in each process system flow chart template in the diagram design template library; and extracting the process system flow chart template in response to a successful match between the main equipment and the equipment in the process system flow chart template.

[0060] In this optional implementation, the principal equipment is the primary equipment in the process system flow chart template and is also the key equipment in the drawing requirement information. Different process system flow charts have different principal equipment. For example, in a flow medium transmission diagram, the pipeline is the principal equipment; in a compressed air station diagram, the air compressor main unit is the principal equipment. The above-mentioned determination of the principal equipment based on the target major category, target minor category, and equipment information includes: determining the primary function of the process system flow chart based on the target major category, target minor category, and equipment information, and extracting the equipment with the greatest impact on the primary function from the equipment information as the principal equipment.

[0061] In this optional implementation, each process system flow chart template in the graphic design template library is a general framework composed of graphic symbols, text annotations, and connecting lines, while the equipment in the process system flow chart template is information identified by graphic symbols and text annotations. Matching the main equipment with the equipment in each process system flow chart template in the graphic design template library includes: determining the graphic and text annotation information of the main equipment in the current category, calculating the similarity between the graphic and text annotation information of the main equipment and the equipment identified in the process system flow chart template, and determining that the main equipment matches the equipment in the process system flow chart template if the similarity is greater than a similarity threshold.

[0062] The method for extracting a process system flow chart template provided by this optional implementation method determines the main equipment based on the target major category, target minor category and equipment information; matches the main equipment with the equipment in each process system flow chart template in the diagram design template library; in response to a successful match between the main equipment and the equipment in the process system flow chart template, extracts the process system flow chart template, and extracts the process system flow chart in the process system flow chart template through the main equipment, thereby improving the reliability of the process system flow chart template.

[0063] Optionally, the above-mentioned extraction of process system flow chart templates from the diagram design template library based on target major categories, target minor categories and equipment information includes: determining the number and type of main equipment and auxiliary equipment based on target major categories, target minor categories and equipment information; matching the number and type of main equipment and auxiliary equipment with the equipment in each process system flow chart template in the diagram design template library; extracting the process system flow chart template in response to the successful matching of the main equipment with the equipment in the process system flow chart template. Taking the air compressor station as an example, the air compressor station corresponds to different system modes of the diagram design template library according to the number and type of air compressor host and auxiliary equipment settings, so it is necessary to call the corresponding process system flow chart template according to the number and type of equipment. Among them, the auxiliary equipment is non-main equipment relative to the main equipment.

[0064] In some optional implementations of the present disclosure, the above-mentioned determination of the equipment parameter values ​​of each device in the process system flow chart template based on parameter information includes: based on the parameter information, selecting the equipment parameter calculation formula of the specific equipment from the diagram design template library; based on the equipment parameter calculation formula, calculating the equipment specifications of the specific equipment in the process system flow chart template to obtain the equipment parameter value of the specific equipment; based on the parameter information, extracting the equipment parameter value of the non-specific equipment, and using the equipment parameter value of the specific equipment and the equipment parameter value of the non-specific equipment as the equipment parameter value of each device in the process system flow chart template.

[0065] In this optional implementation, the equipment in the process system flow chart template includes specific equipment and non-specific equipment, wherein the specific equipment is the equipment that requires calculation of equipment parameter values, while the non-specific equipment is the equipment that does not require calculation and the equipment parameter values ​​can be directly derived from the parameter information.

[0066] In this optional implementation, when constructing a graphic design template library, a specific equipment identifier can be used to mark a specific equipment in the process system flow chart template, and an equipment parameter table can be configured for the specific equipment. In order to facilitate the calculation of the equipment parameter value of the specific equipment, the equipment parameter calculation formula of the specific equipment can be stored accordingly. For example, for the calculation of pipelines, there is an accurate equipment parameter calculation formula. The equipment parameter is used to characterize the correspondence between the medium flow rate and the pipe diameter of the pipeline. When the parameter information has the pipe diameter and the medium flow rate, the equipment parameter calculation formula related to the pipe diameter and the medium flow rate can be directly determined. The pipe diameter size can be directly calculated through the equipment parameter calculation formula. The pipe diameter size is the equipment specification, and the equipment specification is the equipment parameter value of the pipeline (equipment parameter) of the pipeline (specific equipment).

[0067] This optional implementation provides a method for calculating the equipment parameter values ​​of each device. By selecting the equipment parameter calculation formula from the drawing design template library, the drawing parameter values ​​of each device in the process system flow chart template are calculated. This can make the equipment parameter calculation formula completely match the determined process system flow chart template, thereby improving the reliability of the equipment drawing parameter value calculation.

[0068] Optionally, the above-mentioned determination of the equipment parameter values ​​of each equipment in the process system flow chart template based on the parameter information includes: selecting the equipment parameter calculation formula of the specific equipment from the diagram design template library based on the parameter information; calculating the equipment specifications of the specific equipment in the process system flow chart template based on the equipment parameter calculation formula, displaying the calculated equipment specifications, receiving the user's confirmation information on the displayed equipment specifications, and using the equipment parameter value corresponding to the user's confirmation information as the equipment parameter value of the specific equipment.

[0069] In some optional implementations of the present disclosure, the updating the process system flow chart template based on the device parameter value to obtain the target process system flow chart includes: screening the historical parameter value from the drawing design template library based on the device parameter value; generating a process parameter value based on the historical parameter value and the device parameter value; and modifying the specification of the device in the process system flow chart template using the process parameter value to obtain the target process system flow chart.

[0070] In the optional implementation, the historical parameter value is a device parameter value obtained by the device parameter in a historical time period, which can provide a certain reference with respect to the currently obtained device parameter value. The process parameter value is a parameter value selected from the historical parameter value and the device parameter value, which is suitable for generating the target process system flow chart. The suitable standard can be determined based on a drawing drawing standard, for example, the drawing drawing standard is that the parameter value difference in a certain time interval does not exceed a difference threshold.

[0071] In the optional implementation, the device parameter value can be a fixed range value of the device parameter, or a plurality of range values of the device parameter, such as a pipe diameter value of the pipe. The pipe diameter calculated by the parameter calculation formula is selected according to the range, that is, a range. If the historical parameter value is already in the drawing design template library, a reasonable value range can be selected by the historical parameter value and the device parameter value. When it is not determined whether the device parameter value is accurate, the historical parameter value and the device parameter value are put together, and the optimal process parameter value is selected to modify the process system flow template, so that the target process system flow chart can be obtained.

[0072] The method for obtaining the target process system flow chart provided by the optional implementation includes: screening the historical parameter value from the drawing design template library based on the device parameter value; generating a process parameter value based on the historical parameter value and the device parameter value; and modifying the specification of the device in the process system flow chart template using the process parameter value to obtain the target process system flow chart. The target process system flow chart obtained by modifying the process system flow chart template using the generated process parameter value can be more accurate, and the accuracy and reliability of the target process system flow chart are improved.

[0073] Alternatively, the device parameter value can be a fixed range value of the device parameter, for example, the pipe diameter is a device parameter. When the pipe diameter size is calculated by the parameter calculation formula, if a fixed flow rate range is directly given in the developed algorithm module, a unique pipe diameter size range can also be calculated. The updating the process system flow chart template based on the device parameter value to obtain the target process system flow chart includes: in response to the device parameter value of a specific device in the device parameter value being a unique value calculated by a fixed calculation parameter, modifying the specification of the device in the process system flow chart template using the device parameter value to obtain the target process system flow chart.

[0074] In a specific example, a P&ID drawing for a compressed air station is required. The user enters the drawing requirement information for "two 100Nm³ compressed air station P&ID drawings." The process system flow chart drawing method begins, retrieving the equipment parameter tables for the two units within the compressed air station from the pre-built diagram design template library. The designer then fills in the parameter information for each device within the station based on the equipment parameter tables. Based on this parameter information, the P&ID drawing template and the required ancillary systems are extracted from the diagram design template library. The data processing system calculates the piping parameters between the manually entered equipment parameters using built-in piping calculation formulas. By comparing the manually entered equipment parameters with existing data in the diagram design template library, the system selects reasonable piping values ​​and enters them into the P&ID drawing template, creating the P&ID drawing.

[0075] The key point of the present invention is to establish a P&ID drawing database and data processing system, and to establish an intelligent query and identification system based on the principle of artificial intelligence. According to the input instructions, the system can retrieve relevant P&ID drawing templates, equipment parameter tables and system pipeline calculation formulas. After calculating the pipe diameters of various parts of the system through the equipment parameters input by the designer, the system intelligently selects reasonable values ​​and fills them into the P&ID drawing template to form a P&ID drawing.

[0076] The present disclosure also provides a method for constructing a graph design template library. Figure 2 A process 200 of an embodiment of a method for constructing a graph design template library is shown. The method for constructing a graph design template library includes the following steps:

[0077] Step 201: Determine multiple major categories based on the acquired engineering project data.

[0078] In this embodiment, engineering project data refers to the collection of structured and unstructured information generated during the entire life cycle of engineering implementation, which runs through the planning, design, construction, operation and maintenance stages. Engineering project data includes: basic technical data, process management data, quality and safety data, operation support data, etc.

[0079] In this embodiment, the above-mentioned step 201 includes: determining at least one process category based on engineering project data; determining multiple major categories based on at least one process category; wherein, the above-mentioned determination of at least one process category based on engineering project data includes: dividing the engineering project data into at least one process type. Specifically, the division of process categories of engineering project data can be systematically classified from two dimensions: technical characteristics and application scenarios, such as division according to technical levels and division according to process flow stages. The above-mentioned determination of multiple major categories based on at least one process category includes: establishing a hierarchical structure according to commonly used process categories, and determining each major category according to the hierarchical structure. For example, for a compressed air station, for the process category of the compressed air station, according to the information expressed in each hierarchical structure, the engineering project data of the compressed air station can be divided into multiple major categories such as compressed air station, boiler room, steam turbine room, etc.,

[0080] Step 202: Under each major category, determine multiple different subcategories based on the engineering project data.

[0081] In this embodiment, under each major category, the specifications of the main equipment and the auxiliary systems in each major category are extracted. The main equipment is the main equipment, such as the specifications of the boiler in the boiler room category are the main equipment specifications; according to the differences in the specifications of the main equipment and the auxiliary systems, they are subdivided into different subcategories, among which the auxiliary systems are auxiliary technical systems constructed to realize the functions of the main equipment system.

[0082] Step 203: Set a corresponding process system flow chart template for each subcategory.

[0083] In this embodiment, each subcategory has its own equipment-related parameter template that needs to be input. Specifically, under each subcategory, all common information is determined, and a process system flow chart template is generated based on the common information.

[0084] Step 204 : determining the equipment parameters of the equipment in each process system flow chart template, and generating an equipment parameter table based on the equipment parameters.

[0085] In this embodiment, the equipment parameters are determined for the equipment information of each equipment in the process system flow chart template, and the equipment parameters are used as fields of the table. A filling area of ​​a corresponding parameter value is set for each field to obtain an equipment parameter table.

[0086] Step 205: construct a diagram design template library based on the major categories, minor categories, process system flow chart templates and equipment parameter tables.

[0087] In this embodiment, the graph design template library is a database. Its construction must adhere to systematic architecture design and standardized management processes. The technical architecture of the graph design template library includes a storage layer and a service layer. The storage layer uses a relational database to store template metadata (such as version numbers and applicable standards), while unstructured graph files use object storage. The service layer builds microservice modules such as template retrieval, version control, and permission management. Specifically, the construction of the graph design template library can refer to the conventional library construction process and will not be repeated here.

[0088] The method for constructing a diagram design template library provided by the present disclosure comprises the following steps: first, based on the acquired engineering project data, a plurality of major categories are determined; second, under each major category, a plurality of different minor categories are determined according to the engineering project data; third, a corresponding process system flow chart template is set for each minor category; third, the equipment parameters of the equipment in each process system flow chart template are determined, and based on the equipment parameters, an equipment parameter table is generated; finally, a diagram design template library is constructed based on the major categories, minor categories, process system flow chart templates and equipment parameter tables; the process system flow chart categories are refined into a data system architecture to form an effective resource library, which greatly improves the accuracy of the design of the diagram design template library; and as the process system flow chart templates are continuously accumulated and improved, the formed diagram design template library becomes more practical and convenient for generating process system flow charts.

[0089] Optionally, the graphic design template library provided by the present disclosure may also store parameter calculation formulas. The above-mentioned graphic design template library construction method also includes: determining device parameters of a specific device based on device parameters; determining a device parameter calculation formula for the device parameters based on the device parameters of the specific device; and adding the device parameter calculation formula to the graphic design template library.

[0090] Optionally, the above-mentioned method for constructing a diagram design template library further includes: obtaining expert system design information, user feedback optimization information, and a standard template; determining a revised standard template based on the expert system design information, user feedback optimization information, and the standard template; comparing the revised standard template with the process system flow chart template in the constructed diagram design template library, and in response to a large difference between the process system flow chart template in the diagram design template library and the revised standard template, modifying the process system flow chart template to obtain a modified process system flow chart template. To this end, the diagram design template library in the present disclosure supports dynamic updates, including changes in industry standards, addition of user-defined templates, or automatic optimization of templates through artificial intelligence algorithms.
