1 is a block diagram illustrating a computer-implemented apparatus for performing a pipe modeling rule checking method according to an embodiment of the present invention.

Referring to FIG. 1, the computer execution apparatus 100 includes an input unit 110, a pipe modeling rule checking unit 120, an output unit 130, a database 140, and a control unit 150.

The computer execution apparatus 100 receives selection information on a specific piping diagram from a user, receives the piping diagram from an internal or external database, extracts pipe pairs from the piping diagram, and determines whether each pipe modeling rule is satisfied And stores and outputs the pipe modeling rule check result. For example, the computer execution device 100 may correspond to a server, a desktop, or a laptop.

The computer-executable apparatus 100 may provide a pipe modeling rule checking program implemented as a computer-readable recording medium. Here, the provision may include distribution of a computer program, and execution of a computer program in a virtual or cloud computing environment.

The input unit 110 receives selection information on a pipe line to be inspected by the user.

Here, the piping diagram includes information of pipes that are produced in a specific space unit and placed in the space, and can be stored in the database 140 and updated.

In one embodiment, the input 110 may provide a user interface to allow the user to select a pipeline.

FIG. 3 is a diagram illustrating a user interface provided by the computer execution apparatus 100 shown in FIG.

Referring to FIG. 3, the user interface provides a list 310 of pipelines and an execute button 320 for pipelines previously stored in the database 140.

In one embodiment, the user interface provides a list 310 of the pipelines that are grouped by zone on the left side of the output screen, and may receive selection information for the pipelines of the particular region from the user. The user interface can display selection results by color reversal (e.g., changing color from a white background to a blue background) when a particular pipeline is selected.

In one embodiment, the user interface may provide a list of pipes that includes pipes belonging to the pipe diagram, if the pipe diagram is selected in the list 310.

For example, if a specific space named ZONE 3B3000110 defined by the designer is selected by the user, the user interface provides information about the AB-001-12A_001 through AO-001-80A_007 pipes belonging to ZONE 3B3000110 through a pipe list can do.

Here, ZONE 3B000110 corresponds to the identification number indicating the specific area of the vessel assigned according to the promise between the designers, and PIPE AB-001-125A_001 corresponds to the identification number of the pipe assigned according to the promise between the designers. (Mm, for example, 125A) information on the specifications (eg, clean water pipes, oil pipes, gas pipes AB, AC, AD respectively)

In one embodiment, the user interface provides an Execute button 320 with a [Run] indication to the right of the output screen to enable pipe modeling checking for the selected pipe diagram.

The pipe modeling rule checking unit 120 extracts at least one pipe from the received pipe map, determines the pipe to be inspected, and checks whether each of the extracted pipes satisfies the pipe modeling rule.

In one embodiment, the pipe modeling rule checking unit 120 may sequentially extract the pipe information stored in the received pipe diagram based on the identification numbers of the pipes.

Here, the piping diagram includes information on the types of pipes and their location information and the connection relationship between the pipes, and also includes information on the types of pipes, such as the type, shape, size, diameter, And information on the type and position of the pipe head or tail, and further information on other accessories such as valves, accessory, and the like.

In one embodiment, the piping diagram may include a pipe list containing the pipe identification number assigned according to the location of the pipe, and a history of modeling rule inspection of the pipe. Here, the inspection history may correspond to a pipe modeling rule check result including confirmation information that a user confirms a problem with respect to a specific pipe.

In one embodiment, the pipe modeling rule checking unit 120 checks whether there is a past pipe modeling rule check history for at least one extracted pipe, and if there is no past pipe modeling rule check history, Can be determined as objects to be inspected. Here, the inspection history corresponds to a past inspection result in which a pipe modeling rule check is performed on a specific pipe, and a pipe modification or adjustment is performed on the pipe in accordance with the pipe modeling rule violation.

Accordingly, the pipe modeling rule checking unit 120 can exclude duplicate checking of pipes that do not require modeling rule checking due to an inspection history, or even if a pipe violates a modeling rule, , A specially manufactured pipe) can be excluded so that a quick inspection can be performed.

The pipe modeling rule checking unit 120 can check whether each extracted pipe pair satisfies the pipe modeling rules.

Hereinafter, the process of checking whether or not the pipe modeling rule and the pipe inspection rule for the pipe are satisfied, that is, the inspection process for the pipe will be described in detail.

In one embodiment, the pipe modeling rule includes a flange rule for comparing flange angles of mutually contacting pipes, a recorder for determining whether to connect based on the position of the head and tail of adjacent pipes Recorder rules may include a Combination rule to determine whether each of the heads and tail of the pipes contacting each other is implemented as a flange and includes a gasket between the pipes.

Each of the pipe modeling rules will be described in detail below.

The specification cross rule corresponds to a check item for checking whether the attribute of the extracted pipe matches the code of the reference model stored in the database 140. [

For example, when the code AG of the reference model stored in the database corresponds to a branch and a gas pipe, the pipe modeling rule checking unit 120 determines that the pipe under examination 3112110S82X (the model number arbitrarily given by the designer) Code, and if it is not satisfied, an error message such as [Inconsistency in modeling between pls1] and a detailed message such as [data PIPEMAT model 3112110S82X spec AG] Detail Message) can be generated.

Here, pls1 corresponds to the folder or file in which the specification of the pipe is stored, and PIPEMAT corresponds to the table describing the specifications for each pipe.

The angle rule corresponds to an inspection item for checking whether the angles of the extracted pipe and the reference model stored in the database 140 coincide with each other.

For example, when the pipe to be inspected corresponds to an elbow and an angle of 45 degrees, and the specification of the reference model BL corresponds to an angle of 90 degrees, the pipe modeling rule checker 120 determines that the two angles do not coincide with each other , And generate a detailed message including an error message such as [Not match with code] and an angle of each of the reference model and the inspected pipe, such as [spec 90 angle 45].

The flange rule corresponds to an inspection item for judging whether or not the flange angle of the first pipe to be inspected coincides with the flange angle of the second pipe connected thereto and it is possible to check whether or not the flange axis directions of the pipes to be connected coincide with each other have.

For example, when the flange axial directions of the first and second pipes appear in the form of vectors such as (0, -0.998, -0.5233) and (0, -1, 0) in the three-dimensional space coordinates, The inspection unit 120 can confirm that the directions of the two vectors are not the same, and can generate a detailed message including an error message such as [Abnormal Flange Rotation] and flange direction information of the pipe.

Meanwhile, the output unit 130 may output a modeling image of the pipes together with the inspection result, and may allow the user to easily recognize the problem. The output unit 130 may output the modeling image for the pipe to other inspection items.

The recorder rule corresponds to a check item for determining whether or not a pipe is connected based on the position information of the pipe pair.

For example, if the head portion of the first pipe is located at (8860, -9460, 4042) in three-dimensional spatial coordinates, the length of the first pipe corresponds to 4000 mm and the position of the head portion of the second pipe is (8860, -4680 , 4042, the pipe modeling rule checker 120 can calculate that the tail portion of the first pipe is located at (head position + pipe length) = (8860, -5460, 4042) It is possible to judge that the position is different from the position of the head part. As a result, the pipe modeling rule checking unit 120 can determine that the pipe is not stored in the interval (8860, -5460, 4042) to (8860, -4460, 4042) A detailed message including position information of a message and a pipe pair can be generated.

The connection rule corresponds to an inspection item that can determine whether fittings are normally connected.

Here, the fitting corresponds to a piping accessory of a metal that joins a pipe and a pipe, and may be, for example, an elbow, a union, or the like.

For example, if the center axes of the five and the elbow do not coincide (Alignment), or if the orientation directions do not coincide with each other, the pipe modeling rule check unit 120 judges that the connection rule is not satisfied And can generate detailed messages such as [Position of next 88860, -10513, 4042 but 88860, -11914.3, 4052] that contain error messages such as [Mis-Aligned Pipeline] and location information of pipes and elbows . Here, [but] indicates the position of the fitting to be connected to the inspection object.

The coupling rule corresponds to an inspection item for judging whether the connecting portion of the pipe pair is connected in the order of flange, gasket and flange.

For example, when the first pipe has a flange at the tail portion, the second pipe has no flange at the head portion, and the gasket is positioned between the two portions, the pipe modeling rule checker 120 checks the pipe 2 pipe is connected to the flange + gasket, it can be judged that the coupling rule is not satisfied. At this time, the pipe modeling rule checker 120 can generate a detailed message describing the problem in detail, such as an error message such as [Abnormal Flange / Gasket Combination] and [Next is not flange end type].

The redundant fitting rule corresponds to a criterion for judging whether or not a pipe pair is located at a specific position in a redundant manner.

The pipe modeling rule checking unit 120 can determine whether the pipes are duplicated based on the pipe pair location information. If the pipe pairs are overlapped with each other, the pipe modeling rule checking unit 120 includes error information such as [Overlapped fitting! A detailed message can be generated.

The head-to-tail connection rule is a criterion for judging whether or not each head and tail are connected based on information about the position and direction of a pipe to be inspected and a pipe connected thereto.

For example, the pipe modeling rule checking unit 120 determines that the pipe modeling rule is not satisfied when the first pipe tail location and direction information to be inspected are not the same as the head location and direction information of the second pipe, A detailed message including an error message such as [Not Connected Head-Tail!] And location information and direction information of pies can be generated.

A branch rule corresponds to a check item to check whether or not there is branch information coupled to a pipe. For example, when there is only the name of the branch B to be associated with the specific pipe A, the pipe modeling rule checking unit 120 can determine that the branch B does not satisfy the name but only the name of the branch B, Branch Name Only!] And [Hbore size is null] indicating that there is no diameter size information of the pipe.

The fitting rule is a criterion for confirming whether a fitting corresponding to the piping fitting of the connecting metal is present when the pipe is connected to the pipe.

For example, if there is a head and a tail of the pipe but there is no fitting, the pipe modeling rule check unit 120 can determine that the fitting rule is not satisfied, and that only the head and tail are designated and the fitting is omitted [ , And an error message such as " Head-Tail Information Only! &Quot;, and [hbore size is exist but mem count is 0] indicating that the fitting does not exist.

In one embodiment, when the determined pair of pipes does not satisfy at least one of the pipe modeling rules, the pipe production rule checking unit 120 checks information of the pipes that do not satisfy the pipe modeling rule and the pipe modeling rule Results can be generated.

Here, the inspection result may correspond to a result of performing the pipe modeling rule check, and may include information of pipes that do not satisfy the pipe modeling rule, specific pipe inspection rules that are applied to each of the pipes, Content.

In one embodiment, the inspection result may include a list of pipes and details that do not satisfy the pipe production rule. More specifically, it may include a pipe reference number ref, an error message, and a detail message, which are bases for pipe inspection.

In addition, the left side of the pipe identification number may provide an item to check whether the user has confirmed the pipe.

The output unit 130 outputs the pipe modeling rule check result to the display.

In one embodiment, the output 130 may output the inspection results and the shapes of the pipes as a 3D image based on the pipe diagram.

This allows the user to easily identify and solve problems with the pipe.

The database 140 stores pipe diagrams and pipe modeling rules, and provides specific pipe diagrams and pipe modeling rules to the pipe modeling rule checker 120 under the control of the control unit.

In one embodiment, the database 140 may store the inspection records generated by the pipe modeling rule checker 120. [ More specifically, the database 140 may store the inspection record separately based on the identification number for the pipe, or may store the inspection record in the pipeline, including the inspection record.

Here, the piping diagram can be generated by the piping designer and stored in the database 140, and the piping diagram can be generated through a separate program.

The control unit 150 controls data flow between the input unit 110, the pipe modeling rule checking unit 120, the output unit 130, and the database 140.

The control unit 140 may control the database 140 to provide the information to the pipe modeling rule checking unit 120 according to the selected pipe diagram through the input unit 110, The results may be stored (e.g., in a text document) in the database 140 or controlled to be displayed through the output 130.

The pipe modeling rule checking unit 120 checks whether the extracted pipe has an inspection history, and determines a pipe having no inspection history as an inspection target of the pipe modeling rule (S230).

The pipe modeling rule checking unit 120 checks whether each of the extracted pipes satisfies the pipe modeling rule (S240).

If the pipe does not satisfy at least one of the pipe modeling rules (S250), the pipe modeling rule checking unit 120 generates a check result including the pipe and the pipe modeling rule (S260).

In one embodiment, the pipe modeling rule checker 120 generates an error message indicating that the specified pipe does not satisfy the specified pipe modeling rule, and a detailed message including the pipe information and reference information. And can include it in the test results.

The pipe modeling rule checking unit 120 sequentially performs pipe modeling rule checking to determine whether the pipe satisfies all of the pipe modeling rules.

When the pipe modeling rule checking unit 120 examines the pipe modeling rule for a specific pipe, the pipe modeling rule checking unit 120 determines whether there is a pipe pair extracted by the pipe modeling rule checking unit 120 and not yet inspected (S270 ), The above steps (S250 to S270) are repeatedly performed until pipe modeling rule checking is performed on all extracted pipe pairs.
