Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a piping element design method,

TECHNICAL FIELD The present invention relates to a computer-aided design method for various piping such as plant piping for petrochemical and power generation facilities, water supply and drainage, and construction piping for heating and cooling, and a program for implementing the same, and more particularly to piping, piping, (DB) in which a type of pipe element, identification information, contact information, characteristic value, and so on are built, and the identification of other pipe elements connected to the corresponding pipe element as contact information for each pipe element And the joint between the piping elements such as the weld joint is also regarded as the piping element, thereby preventing duplication of the piping element identification information in the process of computing the piping design, and at the same time, It is possible to suppress the unnecessary change of the piping element identification information.

Large-scale and complicated piping facilities are required in accordance with the trend of large-scale and advanced construction of various plants and buildings. Therefore, it is required to design and manufacture design books such as drawings, bill of materials (BOM) and construction plans Processing techniques are being actively applied.

The basic application of computational processing techniques in piping design is to construct piping plans through a drawing program and to create bill of materials through a spread sheet, As a precondition, it is merely to perform construction and document preparation and simple calculation through a computer program.

Thus, a method of forming a database of the piping element and the like and constructing a drawing based on the database has been attempted, for example, Japanese Laid-Open Patent Application No. 2004-100390.

Conventional piping element-based piping drawings including the above-mentioned Japanese Laid-Open Patent Application No. 2004-100390 are obtained by extracting piping element specifications preliminarily constructed in a database form, the construction of corresponding piping elements is automatically performed on the piping system, In the selection process, a symbol corresponding to an individual piping element is output on the screen to provide a graphical user interface, which is improved compared to the conventional simple computation. However, There is a problem in that it is not possible to sufficiently provide the necessary functions in designing actual piping facilities such as organic connection between piping elements, free addition of piping elements, and free insertion of piping elements in the existing piping combination.

This is due to the fact that the connection relation between piping elements depends entirely on the geometric data such as the piping element and the end point coordinates. When the piping design modification such as piping element addition is made, It is accompanied by the inconvenience that it must be corrected.

In particular, there is a problem in that there is no management function for joints between the piping elements such as weld joints, which is managed as part of the specification that the joint points such as the welding point formed at the end point of the piping element are dependent on the corresponding piping element It is difficult to identify a plurality of individual joint points formed in a piping combination body and it is difficult to identify the individual joint points formed in the pipeline combination body at the time of annotation, A problem arises.

A large-sized piping system for a plant or a ship is constructed by combining a plurality of spools. A spool means a unit piping assembly divided by a process. A part of the piping constituting the spool is welded at a piping plant, Is assembled into a spool, and a pipe drawing is also generally made for each spool.

Therefore, in the spool-based piping system construction method, it is very important to identify and manage the joint type such as field weld and shop weld. As described above, in the conventional piping computer design, There has been a problem that serious errors and defects are caused in the actual piping design and construction.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to provide a piping system and a piping system in which systematic and organic generation and connection between piping elements can be achieved by only intuitive input operation of a user, So that it can be inserted freely.

It also aims to systematize the identification and management of joints between piping elements such as welding points and to prevent errors from occurring.

In the present invention, in order to achieve the above-mentioned object, in setting the connection relation between the piping elements, it is not necessary to depend entirely on the geometry information of the piping elements, By storing the information storage area and storing the identification information of adjacent adjacent piping elements as contact information, the connection relation of each piping element can be accurately set without mutual verification of geometry information.

In addition, rather than managing junction points between piping elements such as welding points as part of a specification dependent on the pipeline elements, that is, as characteristic values, the junction point itself is treated as one pipeline element to which identification information is assigned, And it is possible to identify and manage the junction accurately.

That is, the present invention is constructed and executed on the basis of the above-mentioned solution, and it is an object of the present invention to provide a piping computer design method for creating piping design book by using a computer, An input step (S11) in which a DB (DataBase) to which a characteristic value storage area is allocated is constructed in a storage device of a computer and a type and a characteristic value of the piping element are inputted, an allocation step (S12) (S13) that the identification information, the type and the characteristic value of the piping element are recorded in the DB, the connection input step (S21) in which the type and the characteristic value of the connection target piping element are inputted, (S23) in which the identification information, the type and the characteristic value of the pipeline element to be connected are stored in the DB, and the input step (S11) to the step (S13) included in the DB Of the existing piping element The contact information is updated to the identification information of the connection target piping element in the connection input step S21 to the connection receiving step S23 and the existing piping element identification information is stored in the DB internal contact information storage area of the connection target piping element And a contact connection step (S31).

In addition, after the contact connection step S31 is performed, a designation step S41 for designating a connection point between the piping elements, an insertion input step S51 for inputting the type and characteristic value of the pipeline element to be inserted, (S52) in which the identification information of the piping element is assigned, insertion insertion step (S53) in which the identification information, type and characteristic value of the pipeline element to be inserted are recorded in the DB, The contact point information of the connection point existing piping element is updated to the identification information of the insertion target piping element of the insertion input step S51 to the insertion inclusion step S53, (S61) in which the identification information of the existing piping element is stored, and an insertion connection step (S61) in which the existing piping element identification information is stored is performed. Readable recording medium.

Through the present invention, it is possible to systematically and efficiently manage the piping elements and the joints applied to the design in the piping computational design, maximizing user convenience and minimizing design errors.

This not only improves the quality of piping computer design results, but also reduces the time required for piping computer design and personnel.

The program for carrying out the present invention can be executed by a plurality of computers which are executed in a single computer or connected in a client-server form. The DB is integrated with a program for carrying out the present invention, Or a program and a DB may be separately constructed if they are executed by a plurality of computers.

FIG. 1 is a diagram illustrating a computer screen when a piping element input and connection of the present invention is performed. As shown in FIG. 11, which is a flowchart of the present invention, the present invention includes an input step S11 (Step S13) in which the identification information, the type and the characteristic value of the piping element are recorded in the DB, the connection input in which the type and characteristic value of the piping element to be connected are input A connection assignment step S22 in which the identification information of the connection target pipe element is assigned, a connection reception step S23 in which the identification information, the type and the characteristic value of the connection target pipe element are recorded in the DB, The contact information is updated to the identification information of the connection target piping element, and the contact connection step (S31) in which the existing piping element identification information is stored in the contact information storage area of the connection target piping element.

1, when the program of the present invention is executed and a graphical user interface-based screen is implemented, the user operates the input device of the computer to input the initial piping element, A pipe is selected as an initial piping element. In the input method, a popup menu is outputted through a right button of a mouse and a piping element listed in a pop-up menu is selected. However, The input operation of the piping element can be performed by various methods using a single or a combination of input devices such as a mouse and a keyboard configured in the computer. It is possible to use various methods according to the selection of a person skilled in the art of developing a program in the related art, And therefore, the claims are not specifically limited.

FIG. 2 illustrates a portion of a piping element applicable to the practice of the present invention, and illustrates a pipe, an elbow, and a tee applied in describing a concrete procedure of the present invention to be described later. A reducer, a diffuser, a nipple, a cap, a y-branch, and valves of various sizes can be applied.

As shown in the upper part of FIG. 1 and FIG. 11, in the input step S11, the types of piping elements classified into pipes, elbows, tees, and the like, the lengths L and diameters D, etc., is input. As shown in FIG. 1, after selecting a type of piping element through a pop-up menu and inputting characteristic values of the piping element by operating an input device such as a keyboard, The program of the present invention can be operated in such a manner that the shape of the piping element and the list of piping elements output together are written.

After the input step S11 is performed, an allocation step S12 is performed in which the identification information of the piping element is assigned. In the present invention, the identification information of the piping element is assigned to each piping element The identification number of each piping element is not necessarily sequentially increased or decreased in the form of a serial number in the course of the process of assigning identification information according to the progress of the present invention, It is necessary to give an identification number so that the identification information in which the numbers are combined is not duplicated.

When the input step S11 and the allocation step S12 are completed, the step S13 is performed in which the identification information, the type and the characteristic value of the piping element are stored in the respective storage areas allocated in the DB, , The contents of the DB can be outputted through the form of the piping elements on the computer screen and the list of the piping elements to be outputted together.

As shown in FIG. 2, depending on the type of the piping element, the items of the numerical value indicating the standard as well as the inlet and outlet of the fluid may be different. In the present invention, So that various piping elements can be applied.

That is, as shown in FIG. 2, the pipe, which is the simplest type of piping element, is a piping element having the same inlet and outlet dimensions and a straight line. The characteristic values include a length L and a diameter D, And the DB characteristic values represented by the piping element table of FIG. 1 can be simplified to the length L and the diameter D. However, in the case of the elbow, the inlet and outlet diameter D1 D2 and the inlet side length L1 and the outlet side length L2 may be different from each other. Therefore, in the case of tee, a plurality of outlets are formed. Therefore, It is necessary to set a different characteristic value item for each type of piping element as shown in the piping element table of Fig.

In addition, as described above, in the case of giving the identification information of the piping element composed of the symbol indicating the type of the piping element and the unique identification number assigned to each piping element, (S31) or an insertion connection step (S61), which will be described later, by giving identification numbers each having a combination of a plurality of unit numbers in the case of an elbow or a tee in which directionality is required or a plurality of inlets or outlets are formed, So that the connection relation between the piping elements can be accurately set.

When an identification number combining a plurality of unit numbers such as an elbow or a te is to be assigned, each unit number indicates an inlet and an outlet of the corresponding piping element. The inlet port, the outlet port on the branched channel, It is preferable to sequentially give the unit numbers in the order of the outlets.

After the completion of the recording step S13, after the piping element is set as the existing piping element on the program, the connection input step S21 or the contact connection step S31 for connecting the new piping element to be connected to the existing piping element is performed .

The connection input step S21 is a step of inputting the type and characteristic value of the connection target pipe element and can be performed through an input operation in the same manner as in the input step S11 described above, (S22), and a connection step (S23) in which the identification information, the type and the characteristic value of the connection target pipe element are stored in the DB are performed.

After the connection step S23 is performed, the contact information of the existing piping elements in the input step S11 to the collecting step S13 recorded in the DB, as shown in the shaded part in the piping element table of FIG. 1 A contact connection step of updating the identification information of the connection target piping element in the connection input step S21 to the connection receiving step S23 and storing the existing piping element identification information in the DB internal contact information storage area of the connection target piping element (S31) is performed, thereby establishing the connection state between the piping elements on the program of the present invention.

FIG. 3 is a view illustrating a screen outputting a pipeline combination constructed on the program of the present invention through the above-described process. As shown in FIG. 3, a pipeline combination constituted by a plurality of pipeline elements can be visually confirmed , And the list of piping elements showing the connection relation and specifications of each piping element can be confirmed by reflecting the DB contents.

As described above, according to the present invention, in establishing the connection relationship between piping elements, it is possible to provide a piping system in which the prior art that depends entirely on complex geometry information such as the coordinates of the inlet and outlet of the piping element, The contact information storage area for each piping element is allocated in the database containing the type of the piping element, the identification information and the characteristic value, and the identification information of the adjacent piping element is stored in the contact information, so that the calculation of the geometry information, The connection relation for each piping element can be set accurately.

Accordingly, it is possible to quickly and accurately generate drawings of pipe assemblies substantially reflecting the shapes and sizes of piping elements through the present invention, and also to utilize the DB constructed in the course of the present invention, BOM, Bill Of Material) can also be created easily.

The insertion function of the piping element is performed by a welding point or a screw fastening point It can be usefully used in setting the junction point between piping elements.

In the present invention, the junction point between piping elements such as a welding point is not managed as a part of specifications or characteristic values dependent on the piping element, but the junction point itself is treated as one piping element to which identification information is assigned, By applying the method of applying the identification information of the adjacent piping elements as the contact information, it is possible to accurately identify and manage the joints in the construction and modification of the piping assembly.

The insertion of such a piping element such as a welding point is carried out through the designation step S41 to the insertion connection step S61 as shown in FIG. 12, which will be described as follows.

The designation step (S41) designates a connection point for inserting a pipe element to be inserted, such as a welding point, among the connection points between the piping elements in the built-up piping combination composed of the first two or more piping elements. A pop-up menu in which the insertion target piping elements such as welding points are listed is output, and the insertion target piping element is connected to the insertion target piping element, For example.

When the designation step S41 is completed, an insertion step S51 for inputting the type and characteristic value of the insertion subject pipe element, a step S52 for inserting the identification information of the insertion subject pipe element, The insertion step S53 is performed in which information, type, and characteristic values are stored in the DB.

In the embodiment shown in FIGS. 4 and 5, the welding point is selected as the insertion target pipe element. As can be seen from the pipe element table shown in the drawing, since the welding point is means for joining the adjacent pipe elements, It is not necessary to set a typical characteristic value of a general piping element such as a length, but identification information as a piping element is given, and the identification information of the welding point thus applied is used as contact information of the piping element to which the welding point is connected, It can be usefully used for establishing path information for piping combination and for establishing a welding plan on bill of materials (BOM) and construction plan.

When the inserting step S53 is completed, the contact information of the connecting point existing piping element designated in the designating step S41 is set as the identification information of the piping element to be inserted in the inserting input step S51 to the inserting step S53 And an insertion connection step S61 is performed in which the connection point existing pipe element identification information is stored in the DB contact point information storage area of the insertion subject pipe element so that the insertion of the pipe assembly through the insertion of the pipe element in the program of the present invention The actual completion state setting is completed.

As described above, the completed pipe assembly through the input step S11 to the insertion connection step S61 can provide detailed piping design information substantially reflecting the connection state of typical piping elements such as pipes, elbows, tees, As shown in FIG. 6, when the DB constructed in the course of the present invention is used, it is possible to visually express the detailed connection state between the structure of the pipe assembly and the pipe elements, (Path topology) indicating the path of the fluid and the individual piping elements passing through the fluid by path and the path table describing the flow-out entrance in detail can be generated quickly and accurately.

Meanwhile, the designation step S41 to the insertion connection step S61 are not limited to the insertion of welding points and the like to the connection points between the piping elements constituting the piping combination, but also the insertion of the new piping elements And then a new path is set by adding the connection of the piping element from the inserted piping element as a starting point. The computer screen in the concrete process is illustrated in FIGS. 7 to 10 have.

The modification function of such a pipe assembly can be usefully utilized due to the characteristics of various piping facilities that require frequent design changes in the whole design and construction and require subsequent work such as creation of as-built drawing after completion, As shown in FIG. 7 to FIG. 10, when correcting the piping combination, a new schedule is superimposed while maintaining information on the piping component list of the existing piping combination to implement a multi-layer schedule, thereby managing the modification history of the piping assembly You may.

Fig. 7 shows a state in which the above-described designation step S41 is applied to the correction operation of the pipe assembly. When the user designates the pipe element itself, not the connection point between the pipe elements, the pipe element is divided, As in the element table, the contact information and the characteristic value of one divided piping element among the divided piping elements are modified while the other divided piping element is given new identification information, contact information, and characteristic values.

When the piping elements are designated and the division is completed, the insertion input step S51 through the insertion connection step S61 are performed as shown in FIG. 8, whereby a new piping element is inserted at the dividing point, The connection input step S21 to the contact connection step S31 or the described insertion input step S51 to the insertion connection step S51 to the insertion connection step S51 described above, The correction operation of the pipe assembly can proceed through step S61.

FIG. 10 is an exemplary computer screen outputting path information of a pipe assembly newly constructed through the above-described correction operation. As shown in FIG. 10, the pipe connection structure is visually represented by the structure of the pipe assembly, The path topology and the route table of the pipe assembly can be generated quickly and accurately.
