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

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

Typically, engineering companies, refiners, and chemical companies have design drawings in CAD drawings such as AutoCAD and PDF or Hard Copy formats. In the situation where AI and big data technologies are spreading due to the recent 4th industrial revolution, in order to apply the technology to the entire shipbuilding industry and plant engineering industry, it is necessary to digitize the data held in the PDF or hard copy format.

Looking at the digitization process of the conventional design drawings, first, when a P&ID filed with images, such as PNG, JPG, PDF, etc., created by a customer (hereinafter referred to as "imaged P&ID") drawing is received as a construction contractor, the design engineer recalls The image filed P&ID drawing will be created as a new P&ID drawing.

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

Here, the P&ID is an abbreviation of “Piping & Instrument Diagram,” which means a process flow diagram that expresses the equipment, piping, and electric instrument of a certain process in a diagrammatic form. Intergraph is a design program for creating a P&ID. )'S SP P&ID (SmartPlant P&ID), Aveva's Aveva P&ID, and Autodesk's AutoCAD Plant P&ID.

However, the above-described digitization process of the conventional design drawings was only used to check errors by comparing the digitized design drawings and the imaged drawings with the naked eye, which is the most important information and utilizes data necessary for automation of the design. There was a significant problem. In other words, design products that must be checked whether there are any missing or incorrect entries in the design information written on the imaged P&ID drawings while comparing the imaged P&ID drawings with the newly created drawings. There was a problem of the difficulty of the mutual consistency check.

In addition, since all material items including valves etc. must be created while creating a new drawing, it takes a lot of unnecessary time to create a new drawing and fill the quantity. There was a very difficult problem to manage.

Due to these problems, most of the actual companies have not been able to closely check the results of the calculation, and the accuracy and reliability of the calculation of materials are significantly low. The inconsistency caused many problems such as delays in construction.

According to the above-described conventional method, the demand for technology for digitizing existing drawing data in an image format increases and the related industry has a high ripple effect, but it is difficult to generate profits for a short period of time, and thus the development of drawing automatic drawing technology is slow.

The present invention has been developed to solve such a conventional problem, it is possible to obtain a digitized drawing by automatically modeling symbols, lines, and text in intelligent P&ID (Intelligent P&ID) through a database or imaged P&ID drawing stored in text form. Therefore, the main purpose is to accurately and quickly calculate the estimate and to accurately check the consistency between other designed products.

And additionally connecting a branch line branching from the main line, wherein the branch line is a primary line modeling step of connecting a connector of the main line as a linkage information as link 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 utility lines by combining utility lines in groups of lines that can be connected to each other of the same type in the intelligent P&ID drawings in which the symbols are 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 property information of the line number at the closest location using coordinate information stored in the database. do.

In addition, in the step of converting and storing the database, it may be characterized in that the database includes design information that is automatically recognized and classified in an imaged P&ID drawing, and a process sequence of the design information.

In addition, when the main lines are combined in the step of modeling the primary line, if the main lines cannot find a connection point and cannot be combined into one group, first fine-tune the position of the lines to connect the lines connected to each other. It can be characterized by combining into groups.

In addition, in the step of modeling the primary line, in the method of connecting the branch line with the main line as a target, it may be characterized in that a connector having a coordinate as a connection point is calculated and connected to the connector to be connected. .

In addition, in the modeling of the primary line, the primary lines are connected to each other through a recursive calling technique, and in the modeling of 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.

In addition, when a symbol is connected to the primary line and is recognized as a separate line in the step of modeling the primary line, the lines may be connected.

In addition, in the step of modeling the symbol, when the symbol is not connected because it is not located on the line, it may be characterized in that the symbol is modeled by correcting the location of the symbol with the location of the connected primary line.

In addition, the step of modeling the symbol may be characterized by storing attribute information of a symbol 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, if the symbol is a reducer or a specbreak type, after modeling the utility line, calculate the line and connector to which the symbol of the reducer or the specbreak is connected. After connecting the symbol of the reducer or the spec brake to the primary line, storing the newly generated Pipe Run ID and modifying the existing Pipe Run ID to model the reducer or the spec brake; Can be.

Hereinafter, a method of automatically creating a drawing using design information stored as 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 various different forms, and only the embodiments allow the disclosure of the present invention to be complete, 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, in the description of the present invention, if it is determined that the detailed description of the related known functions or configurations may unnecessarily obscure the subject matter of the present invention, the detailed description will be omitted.

As described above, in the past, P&ID drawings in the form of image files, usually PDF files, have been rewritten by design engineers into new intelligent P&ID drawings, resulting in inconsistencies between design products and front-end engineering design (FEED) data. In the early stage of setup, unnecessary time was spent, and this caused a major problem, especially in carrying out overseas projects.

In order to solve these problems and aggregate design elements through a short time and high accuracy in the initial FEED process, and utilize them in the estimation work, and exclude simple repetitive work by advanced engineers, the present invention improves work productivity and improves design quality. Provides a method to automatically create intelligent P&ID drawings as follows.

The present invention is a method for automatically creating a drawing using a database including design information. The database includes design information that is automatically recognized and classified from the imaged P&ID drawing, or design information extracted through another intelligent P&ID. The SPP&ID (SmartPlant P&ID) among the intelligent P&IDs that write is described as an example.

1 is a flowchart of a method for 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 converted by mapping with predefined intelligent P&ID information, and the correlation and information of the converted data is stored (S100). Since the design information stored in the database is a database that the user selects and uses at random, it can be converted by mapping to match the concept defined by the user. Organize data to convert symbol, line, line number and text information into intelligent P&ID items. When the design information stored in the database is the design information of the line, the type is Capillary, Connect To Process, Electric, Electric Binary, Guided Electromagnetic, Hydraulic, Mechanical, Pneumatic, Pneumatic Binary, Primary, Secondary, Software, etc. Maps to a predefined intelligent P&ID line type. After mapping the information, the association and attribute information of lines and symbols are converted and stored.

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

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 size of the coordinate reference point and the coordinate of the intelligent P&ID are different, the scale is compared and converted through reference point symmetry and stored.

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

When modeling without linking the interconnected lines into a group because they do not fine-tune, data errors occur, the lines do not run side by side and modeling time is consumed. First, the line positions are fine-tuned to combine the interconnected lines into one.

A recursive call technique can be used as a method of combining the lines. The Recursive Algorithm means that any function calls itself, and in the present invention, any symbol or line calls another symbol or line connected using the stored connection information, and the process continues. Repeatedly to combine 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 among the processes to be designed, 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 process in which the first branch line 330 branches to the main line, and (c) and (d) are the second branch. Line 340 is a process of branching. The lines 330 and 340 that separate the main lines become branch lines. The connector is necessary for symbol and line connection when drawing with SPP&ID among the intelligent P&IDs. The connector is connection information required to find a line to which a symbol and a branch line are attached. When the branch line and a symbol are attached, a new connector is generated on the target line based on the corresponding branch line and symbol. In FIG. 3(b), the first branch line 330 is connected by using the connector information of the main line 300 as an object, and two connectors 310 and 320 are generated after connection. In FIG. 3(c), a 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 and 321 and 322 are generated on one main line 300. .

4 is an exemplary view for explaining a method of calculating a connector to connect a branch. Pipe Run ID is the unique ID of the modeled line combined into the above groups. When the corresponding Pipe Run ID is searched, SP_ID and Representation Type can be checked. If Representation Type is “9”, it is a connector, and if it is “46”, it is a branch. 400 is an embodiment having only one main line, and the starting point and the ending point have coordinates of (1, 1) and (5, 1), respectively. In addition, since the symbol and branch line are not yet connected, if you query the Pipe Run ID of the line, you can see that there is only one connector object. 410 is one branch line connected, and since 400 connectors are one, the branch line is connected by inputting coordinates and connectors to which branch lines are connected as connection information. At this time, after the branch line is generated, the coordinates of the branch line are stored. After connecting, you can confirm that one branch line object and two connector objects were created by querying the Pipe Run ID. When connecting a branch line to one of the two connectors, such as 420, the connector to which the branch line is connected must be found, but only the object information of the same Representation Type as in the embodiment of 410 finds a connector to which the branch line is connected. Can't. The present invention uses a line point coordinate calculation method to solve this. The coordinates to which the branch line should be connected are extracted from the database, and the pointers of the branch lines of other lines are used to find the start point and the end point of each connector using the coordinates saved when the branch line is connected, and find the connector to be connected among the two connectors. Calculate and combine. In the embodiment of FIG. 4, the coordinates to which the branch lines are connected (3,1) are extracted, and the starting and ending points of the 421 connector (1,1) and (2,1), and the starting and ending points of the connector of 422 (2) After finding ,1) and (5,1), calculating the coordinates, it can be seen that the branch line is connected to the 422 connector. After connecting the branch lines, the coordinates of the connection points are stored and repeated to connect the other branch lines.

When a symbol is connected to the primary line and is recognized as a separate line, the line may be connected. The case where the symbol is connected to the primary line and is recognized as a separate line means that the line occupied by the symbol is recognized as not being connected due to the area occupied by the symbol when recognizing the imaged drawing as shown in FIG. 5 and When the primary line is modeled due to unrecognized or misrecognized, it does not include a case where the lines are not connected to each other. If it is modeled (510) as an unconnected line, different pipe run IDs are generated, and the symbol can be modeled due to the characteristics of the image in the step of modeling the symbol, which is a subsequent step, but the line and connection are abnormally modeled without correct positioning. . If the unconnected line is connected to an appropriate location for modeling (520) and assigned to a single Pipe Run ID, in the modeling of the symbol that is a subsequent step, the connector to which the symbol is located can be found (530), and the line is one. The reason for merging is to draw correctly with speed improvement and coordinate correction of image recognition. This is one of the technical features of the present invention for efficient modeling using intelligent P&ID.

Next, in the P&ID drawing where the primary line is modeled, lines and connectors to which symbols are connected are calculated, and the symbols are connected to the primary lines to model the symbols (S120).

6 is an embodiment in which the symbol is connected to the primary line, and there is a line connected to each connector of the symbol 610 and finds a connector connected by calculating an association relationship with a unique ID (UID) of the line. Model the symbol in the corresponding connector. The method of finding and modeling the connector is the same as the method of modeling the primary line, so a detailed method is omitted. When modeling a symbol, the type that can be connected to the primary line is determined, and the type of the line and the symbol type must be the same to connect. Therefore, in the case of an instrument other than the primary type, it is connected to the electric line later. Since it will be, the symbol is modeled at the designated position even if it is not connected by 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, it may be characterized in that the symbol is modeled by correcting the location of the symbol to the location of the connected primary line. The method of modeling the symbol is by using a connector and coordinates. If the coordinates of the symbol and the coordinates of the line to be connected are different, modeling is impossible or cannot be located at the correct coordinates. Therefore, the symbol can be modeled by solving the above problem by correcting the position of the symbol to the position of the connected primary line.

The property information of the symbol stored in the database may be stored in association with the symbol property of the intelligent P&ID. The attribute information of the symbol may 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 are preceded by mapping and storing the database. Through the process of linking the attribute information of the symbol, the attribute of the symbol can be displayed on the drawing of the intelligent P&ID.

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

In the step of modeling the utility line, if the type of the connected Utiliy line does not match the type of the symbol, a connection can not be made and a report can be output.

7 is an exemplary view showing a process of modeling the utility line, and 700 outputs a report that an invalid 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 the utility line is incorrectly registered in the stored database, which helps in the consistency check.

When the symbol is a reducer or a specbreak type, after modeling the utility line, calculate the line and the connector to which the symbol of the reducer or the specbreak is connected, and calculate the symbol of the reducer or specbreak. After connecting to the headline, it may be characterized in that it further comprises the 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 size of the piping is changed in the reducer, and the fluid type is changed in the spec brake, and the line property is changed before and after the reducer and the spec brake. Due to the characteristics of the reducer and the spec brake 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. After all the symbols and lines are modeled, the reducer and the spec brake can be modeled.

8 is an exemplary diagram showing 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 divided into two, and the connector is also separated in this process. Among the separated Pipe Run IDs, the existing Pipe Run ID is modified and the new Pipe Run ID is stored 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 the attribute information of the line number at the closest location using coordinate information stored in the database ( S150).

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

Text excluding the line number is modeled at coordinates stored in the database, and in the case of equipment among text 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 drawings that are objects of comparison of design products such as imaged P&ID drawings, it is easy to compare the consistency of design products because they can be compared at the same location.

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