Description

{Method of automatically creating Intelligent PID drawings by using information of design stored in a database}

The present invention is a method of automatically creating drawings using design information stored as a database in a storage medium, and in more detail, the database is composed of design information classified from an imaged P&ID or design information extracted through other intelligent P&IDs. have. This relates to a method of automatically creating drawings using an intelligent P&ID.

Typically, engineering companies, oil refining companies, chemical companies, etc. hold design drawings in CAD drawing formats such as AutoCAD and PDF or Hard Copy format. In a situation where AI and big data technologies are spreading due to the recent 4th industrial revolution, digitalization of the data held in the PDF or Hard Copy format is essential in order to apply the technology to the shipbuilding industry and the plant engineering industry as a whole.

Looking at the digitization process of the conventional design drawings by the contractor, first, when the P&ID (hereinafter referred to as "imaged P&ID") that has been designed and created by the customer as an image file (hereinafter referred to as "imaged P&ID") is received by the contractor, the design engineer will The image filed P&ID drawing is created as a new P&ID drawing.

In addition, oil refineries and chemical companies with long history create digitalized drawings through manual input while visually checking the design documents imaged in PDF and existing hard copy that they have in order to introduce the latest IT solutions.

Here, the P&ID is an abbreviation of “Piping & Instrument Diagram,” meaning a process flow diagram that clearly expresses facilities, piping, and electrical instrumentation of a certain process in a diagram format. The design program for creating P&ID is Intergraph )'S SP P&ID (SmartPlant P&ID), Aveva's Aveva P&ID, and AutoDesk's AutoCAD Plant P&ID.

However, the digitization process of the conventional design drawings described above was only used to check errors by comparing the digitized design drawings with the imaged drawings with the naked eye.This is the most important information and data required for automation of design, etc. There was a considerable problem. In other words, while comparing the imaged P&ID drawing and the new drawing created, among the design information written on the imaged P&ID drawing, it is not created as a new drawing, and it is necessary to check whether there is any omissions or mistakes between design products. There was a problem of the difficulty of checking mutual consistency.

In addition, since all material items including valves must be created while creating a new drawing, it takes a lot of unnecessary time to create a new drawing and fill in the quantity, and if the piping layout is changed, the calculation material is modified and updated. There was a problem that was very difficult to manage.

Due to this problem, most of the actual companies are not able to carefully check the calculation results, and the accuracy and reliability of material calculations are remarkably low. Such errors in material quantity calculation and design information between design products Inconsistency caused many problems, including delays in construction.

According to the above-described conventional method, the demand for technology to support digitization of existing drawing data in image format is increasing and the ripple effect of related industries is high, but the development of automatic drawing drawing technology is slow due to difficulty in generating short-term profits.

The present invention was developed to solve such a conventional problem, and it is possible to obtain a digitized drawing by automatically modeling symbols, lines, and texts in an intelligent P&ID (Intelligent P&ID) through a database stored in text format or an imaged P&ID drawing. The main purpose is not only to calculate the estimate accurately and quickly, but also to accurately check the consistency between products of other designs.

The present invention for achieving the above object is a method of automatically creating an intelligent P&ID (Intelligent P&ID) drawing using design information stored in a database, and converting the design information stored in the database by mapping it with predefined intelligent P&ID information. Storing the relationship and information of the converted data; When modeling the primary line constituting the design target process from the converted data by mapping it with the intelligent P&ID information, the main line is connected by combining the main process lines among the design target processes. And a primary line modeling step of additionally connecting a branch line branching from the main line, and connecting the branch line using a connector of the main line to be the target as connection information; Calculating a line and a connector to which the symbol is to be connected in the intelligent P&ID drawing in which the primary line is modeled, and modeling a symbol connecting the symbol to the primary line; Modeling a utility line by combining a utility line into a group of lines that can be connected to each other of the same type in the intelligent P&ID drawing in which the symbol is modeled; In the intelligent P&ID drawing in which the utility line is modeled, the primary line and the utility line are modeled by linking attribute information of a line number at the nearest position using coordinate information stored in the database. do.

Further, in the step of converting and storing the database, the database may include design information automatically recognized and classified in the imaged P&ID drawing, and a process sequence of the design information.

In addition, when combining the main lines in the modeling of the primary lines, if the main lines cannot be combined into one group because they cannot find a connection point, first fine-adjust the position of the lines to combine the connected lines into one group. It may be characterized by combining into groups.

In addition, in the method of connecting the branch line with the target main line in the step of modeling the primary line, a connector in which coordinates as a connection point are located may be calculated and connected as the connector to be connected. .

In addition, in the step of modeling the primary line, the lines connected to each other through a recursive calling technique are combined, and in the step of modeling the utility line, the utility lines are connected to each other of the same type through a recursive calling technique. It can be characterized by combining the lines to be.

Further, in the step of modeling the primary line, when a symbol is connected to the primary line and thus recognized as a separate line, the lines are connected.

In addition, in the step of modeling the symbol, when the symbol is not connected because it is not located on the line, the position of the symbol may be corrected to the position of the connected primary line and then modeled.

In addition, the step of modeling the symbol may include storing the symbol attribute information stored in the database in association with the symbol attribute of the intelligent P&ID.

In addition, in the step of modeling the utility line, when the symbol is a reducer or specbreak type, after modeling the utility line, the line and connector to which the reducer or specbreak symbol is connected are calculated. After connecting the symbol of the reducer or the spec brake to the primary line, storing the newly created Pipe Run ID and modifying the existing Pipe Run ID to model the reducer or the spec brake; characterized in that it further comprises I can.

In addition, in the step of modeling the utility utility, when the connected utility line type does not match the symbol type and thus cannot be connected, it may be displayed to the user to output a report.

Further, in the step of modeling the line number, the line number may be modeled in coordinates stored in the database.

In addition, in the step of modeling the line number, modeling the text excluding the line number to the coordinates stored in the database, and in the case of an equipment among texts excluding the line number, associating the modeled text with a device symbol. It can be characterized.

In addition, in the modeling of the line number and text, if the value of the attribute information is not the item attribute attribute of the intelligent P&ID, the result may be displayed to the user and a report may be output.

If drawings are automatically digitized through the above method, most tasks such as drawing creation, material calculation, basic design information such as device list, line list, and instrument list calculation are automatically generated by counting design elements with high accuracy in a short time. It is possible, and it helps to improve work productivity by eliminating the simple and repetitive task of manually calculating design elements by advanced engineers.

In addition, if the drawing is automatically generated using the data generated by the above method, rather than the conventional method in which the drawing was drawn directly from the imaged P&ID, design product consistency is maintained and design quality can be improved. This solves problems such as waste of time, omissions, and errors of plant engineering companies, which were caused by the conventional visual inspection and drawing drawings.

In addition, when verifying the accuracy after 3D modeling, it is possible to quickly and accurately verify the accuracy of the created drawing because it can be compared with the stored data.

Hereinafter, a method of automatically creating a drawing using design information stored in a database according to the present invention will be described in more detail with reference to the accompanying drawings.

However, the present invention is not limited to the embodiments disclosed below, but may be implemented in a variety of different forms, only these embodiments are intended to complete the disclosure of the present invention, and are common in the technical field to which the present invention pertains. It is provided to fully inform the knowledgeable person of the scope of the invention, and the invention is only defined by the scope of the claims. For reference, when it is determined that detailed descriptions of known functions or configurations related to the present invention may unnecessarily obscure the subject matter of the present invention, detailed descriptions thereof will be omitted.

As described above, conventionally, design engineers rewritten P&ID drawings in the form of image files, usually PDF files, into new intelligent P&ID drawings. Accordingly, data between design products is inconsistent and FEED (Front-End Engineering Design) data It took unnecessary time to set up the system early, and this caused a big problem, especially in conducting overseas projects.

In order to solve these problems, aggregate design elements through a short time and high accuracy in the initial FEED process, and utilize them for estimating work, and to improve work productivity and design quality by excluding simple repetitive tasks of advanced engineers, the present invention It provides the following automatic intelligent P&ID drawing method.

The present invention is a method for automatically creating drawings using a database including design information, wherein the database is design information classified by automatically recognizing the design information in an imaged P&ID drawing, or includes design information extracted through other intelligent P&IDs. Among the intelligent P&IDs that create an example, SPP&ID (SmartPlant P&ID) will be described as an example.

1 is a flow chart of a method of automatically creating a drawing using design information stored in a database according to the present invention.

First, the design information stored in the database is mapped and converted with predefined intelligent P&ID information, and the relationship and information of the converted data are stored (S100). The design information stored in the database is a database that the user selects and uses, so it can be mapped and converted to conform to the concept defined by the user. Data is organized to convert symbol, line, line number, and text information into intelligent P&ID items. When the design information stored in the database is line design information, the type is Capillary, Connect To Process, Electric, Electric Binary, Guided Electromagnetic, Hydraulic, Mechanical, Pneumatic, Pneumatic Binary, Primary, Secondary, Software, etc. Is mapped to a predefined intelligent P&ID line type. After mapping the information, the relationship between lines and symbols and attribute information is converted and stored.

2 is an embodiment of mapping attribute information of a gate valve among symbols, and an attribute stored as "Option" in a database is mapped to "Option Code" according to the attribute of an intelligent P&ID. In the above way, “Ins. Purpose” means “Insulation Purpose” and “Ins. “Thickness” is mapped to “Insulation Thickness” and “Diameter” is mapped to “Nominal Diameter”. The association relationship includes connection information in which the symbol and the line are connected to the line, and connection information between the text and the symbol.

The database may include design information automatically recognized and classified in an imaged P&ID drawing and a process sequence of the design information. Since the coordinates of the imaged P&ID drawing and the coordinates of the intelligent P&ID have different sizes of the reference points and the coordinates, they are converted and stored through scale comparison and reference point symmetry.

Next, from the data converted by mapping with the intelligent P&ID information, the main line is first modeled by combining the lines connected to each other among the lines with a type of primary, and then the branch line is connected. The entire primary line is modeled by calculating a connector (S110).

Since the lines connected to each other are not finely adjusted and cannot be combined into a group, and when modeling, errors in data occur and the lines are not aligned and a lot of modeling time is consumed. Therefore, the line positions are first finely adjusted to combine the connected lines into one.

As a method of combining the lines, a recursive calling technique can be used. The recursive algorithm means that an arbitrary function calls itself, and in the present invention, an arbitrary symbol or line calls another symbol or line connected by using the stored connection information, and the process continues. Repeatedly combines lines and lines.

3 is an exemplary view showing that the connector of the main line is separated due to the branch line. The main line is a main process line in a design target process, and the branch line is a line attached to the main line. In FIG. 3, (a) is a process of modeling the main line 300, (b) is a branching of the first branch line 330 to the main line, and (c) and (d) are the second branch. This is a process in which the line 340 is branched. The lines 330 and 340 that divide the main line become branch lines. The connector is necessary for connection of symbols and lines when drawing with SPP&ID among the intelligent P&IDs. The connector is connection information necessary to find a line to which a symbol and a branch line are attached. When the branch line and the symbol are attached, a new connector is created on a target line based on the corresponding branch line and symbol. In Fig. 3(b), the first branch line 330 is connected by using connector information of the main line 300 as an object, and two connectors 310 and 320 are generated after the connection. In Fig. 3(c), the second branch line is connected to the right connector 320 among the main lines, and finally, two branch lines 330 and 340 and three connectors 310, 321 and 322 are created in one main line 300. .

4 is an exemplary diagram for describing a method of calculating a connector to connect a branch. The Pipe Run ID is a unique ID of a line modeled by being combined into the group, and when the corresponding Pipe Run ID is searched, SP_ID and Representation Type can be checked. If the Representation Type is “9”, it is a connector, and if it is “46”, it is a branch. 400 is an embodiment with only one main line, and the starting point and the ending point have coordinates of (1,1) and (5,1), respectively. Also, since the symbol and the branch line are not connected yet, it can be confirmed that there is only one connector object by looking up the Pipe Run ID of the line. In 410, one branch line is connected, and since the connector of 400 is one, the branch line is connected by inputting coordinates to which the branch line is connected and the connector as connection information. At this time, after the branch line is generated, the coordinates of the branch line are stored. After connecting, if you search the Pipe Run ID, you can see that one branchline object and two connector objects have been created. When connecting a branch line to one of the two connectors as shown in 420, a connector to which the branch line is connected must be found, but as in the embodiment of 410, the connector to which the branch line is connected is found based on object information of the same Representation Type. Can't. The present invention uses a line point coordinate calculation method to solve this problem. The coordinates to which the branch line is to be connected are extracted from the database, and the coordinates stored when the branch line of the other line are connected are used to find the start and end points of each connector, and the connector to be connected among the two connectors is selected. Calculate and combine. In the embodiment of FIG. 4, the coordinates (3,1) to which the branch lines are connected are extracted, and the starting and ending points of the connector 421 (1,1) and (2,1), and the starting and ending points of the connector of 422 are (2). After finding ,1) and (5,1), if the coordinates are calculated, it can be seen that the branch line is connected to the 422 connector. After connecting the branch line, the coordinates of the connection point are stored, and the other branch lines are connected repeatedly.

When a symbol is connected to the primary line and thus recognized as a separate line, the lines are connected. When the symbol is connected to the primary line and is recognized as a separate line, when the imaged drawing as shown in FIG. 5 is recognized (500), it is recognized that the line is not connected due to the area occupied by the symbol, and This includes cases in which the primary lines are not combined into connected lines when modeling the primary line due to unrecognized or misrecognized. If modeling 510 as an unconnected line, the symbol can be modeled due to the characteristics of the image in the step of modeling the symbol, which is a step that follows different Pipe Run IDs, but the position is not correct and the line and connection are abnormally modeled. . If the unconnected line is connected to an appropriate position to be modeled (520) and assigned as one Pipe Run ID, in the step of modeling the symbol, which is a subsequent step, a connector to be located can be found (530), The reason for consolidation is to correctly draw with speed improvement and coordinate correction of image recognition. This is one of the technical features of the present invention for efficient modeling using an intelligent P&ID.

Next, a line to which a symbol is to be connected and a connector are calculated in the P&ID drawing in which the primary line is modeled, and the symbol is modeled by connecting the symbol to the primary line (S120).

6 is an embodiment in which the symbol is connected to the primary line. A line connected to each connector of the symbol 610 exists, and a connection relationship is calculated using a unique ID (UID) of the line to find a connected connector. Model the symbol on the corresponding connector. Since the method of finding and modeling the connector is the same as the method of modeling the primary line, a detailed method will be omitted. When modeling a symbol, the type that can be connected to the primary line is determined, and the connection is possible only when the line type and the symbol type are the same, so in the case of an instrument other than the primary type, it is connected to an electric line later. Therefore, the symbol is modeled at a designated location even if it is not connected to the primary line (600).

In the step of modeling the symbol, when the symbol is not connected because it is not located on the line, a position of the symbol may be corrected to a position of the connected primary line to be modeled. The method of modeling the symbol uses a connector and coordinates, and if the coordinates of the symbol and the coordinates of the connected line are different, modeling is impossible or cannot be positioned at the correct coordinates. Accordingly, the symbol can be modeled by correcting the position of the symbol to the position of the connected primary line to solve the problem.

The symbol attribute information stored in the database may be linked to the symbol attribute of the intelligent P&ID and stored. The symbol attribute information can be performed in a step after the symbol is modeled, and the symbol attribute of the intelligent P&ID and the attribute stored in the database preceded the step of mapping and storing the database. The symbol attribute may be displayed on the diagram of the intelligent P&ID through the process of linking the symbol attribute information.

Next, a utility line is modeled by combining the utility lines into a group of lines that can be connected to each other of the same type in the P&ID drawing in which the symbol is modeled (S130). Since the method of modeling by connecting the utility lines is the same as the method of modeling the primary line, a detailed method is omitted. The process of modeling the utility line is performed after the process of modeling the symbol in order to model the utility line without error since the utility line may be connected to the primary line through the symbol in the intelligent P&ID. The utility line is connected to the primary line through a symbol, but when a utility line is called without the symbol, the utility line is not connected and a subsequent step cannot be performed. In the primary line modeling process, unless the utility line is connected to the primary line through symbols, all lines including the utility line may be modeled.

In the step of modeling the utility line, if a connection cannot be made because the type of the connected utility line does not match the symbol type, a report may be output.

7 is an exemplary view showing the process of modeling the utility line, and 700 outputs a report indicating that an incorrect utility line is connected to an electric type instrumentation. Through the process of outputting the report, it is possible to find out that the type of utility line is incorrectly registered in the stored database, which is helpful for consistency check.

When the symbol is a reducer or specbreak type, after modeling the utility line, a line and a connector to which the reducer or specbreak symbol is connected are calculated, and the symbol of the reducer or specbreak is applied to the price. After connecting to the headline, it may be characterized in that it further comprises a step of modeling a reducer or a spec brake by storing the newly created Pipe Run ID and modifying the existing Pipe Run ID (S140).

The pipe size of the reducer is changed, and the fluid type of the spec brake is changed, and the properties of the line are changed before and after the reducer and the spec brake. Due to the characteristics of the reducer and spec break type, it is difficult to calculate the connector of the symbol and line because the Pipe Run ID changes before and after the corresponding symbol, and after modeling all symbols and lines, the reducer and the spec break can be modeled.

FIG. 8 is an exemplary diagram illustrating that a reducer symbol is modeled 800 and another Pipe Run ID is generated before and after the reducer symbol. After modeling, the Pipe Run ID is separated into two, and the connector is also separated during this process. Among the separated Pipe Run IDs, the existing Pipe Run ID is modified and the new Pipe Run ID is saved to redefine the Pipe Run ID.

Next, in the intelligent P&ID drawing in which the utility line is modeled, the primary line and the utility line are modeled by linking attribute information of a line number at the nearest position using coordinate information stored in the database ( S150).

9 is a diagram of mapping attribute information of a line number stored in the database with an attribute of Pipe Run. Among the property information of the line number, the Piping Materials Class, Fluid Code, Nominal Diameter, and Tag Seq No are connected and stored, but the Insulation Purpose is not linked. As a method of modeling the line number, first check the data order of the line number and find matching line number attribute information. Thereafter, the connector closest to the position where the line number is to be placed is found, and the line number attribute information corresponding to the line number is connected to the connector to be modeled.

Text excluding the line number is modeled on coordinates stored in the database, and in the case of an equipment among texts excluding the line number, the modeled text and a device symbol are linked.

In the step of modeling the line number and text, the text may be modeled at coordinates stored in the database. When comparing the text with a drawing that is an object of design product consistency comparison such as an imaged P&ID drawing, it is easy to compare the consistency of the design product because it can be compared at the same location.

In addition, in the step of modeling the line number and text, if the value of the attribute information does not match the item attribute of the intelligent P&ID, a report may be output. In Fig. 9, the Insulation Purpose is a case where the value of the database and the intelligent P&ID value do not match, and the value that can be input from the intelligent P&ID is determined, so that "N" in the example outputs a report to the user in a state where input is impossible. It is not input (900). By outputting a report to the user, it is possible to check whether it has been incorrectly entered into the database, and to post-verify attribute information.
