The computer execution apparatus 100 may provide a pipe block coupling inspection program implemented by 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 made in a specific zone unit (e.g., 2nd deck pump room) of the vessel and placed in the space, and can be stored in the database 140 and updated by the designer .

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

More specifically, the user interface includes a key input field 311 for directly inputting a first pipe diagram to be inspected at the top of the output display, a piping diagram for selecting a piping diagram from a list (not shown) And provides a select button 332 (e.g., ce zone).

For example, the user interface may allow the name of the folder or pipe containing the pipe diagram to be entered in the key input field, such as [/ PIPES], or the pipe may also be a folder named [/ PIPES] You can allow selection of names.

The user interface may provide a comparison item 320 directly below the base item 310 and more specifically the second pipe line may be provided in accordance with the purpose such as [pipe / equip zone], [all zone] and [ce zone] The [ce zone] is the same as described in the Base section. Here, [pipe / equip zone] is an item that allows you to select only specific areas (eg pump rooms) for the placement of pipes and equipment, and [all zone] It corresponds to an item which can be selected.

The user interface may provide the inspection zone item 330 under the comparison item 320 and the inspection zone item 330 may include the [GRIDSY] item, the frame, the Longi and the Deck, It is possible to provide an item in which the first pipe line can be selected based on each of them.

Here, the item [GRIDSY] corresponds to an item in which the user can select the first pipe diagram in the grid-shaped coordinates.

In one embodiment, the input unit 120 may select a range of each of the first and second pipelines in block units through a position controller that selects a key-in or a plurality of positions .

More specifically, the input unit 120 can select the first pipe line through the key input method and the position selection method for the frame, the longee, and the deck item, respectively. More specifically, the frame, longee, and deck items are provided with a key input field for inputting a start point and an end point, respectively, to receive input information of a user, or a selection button and a tool To select the first piping.

4 is an example of selecting a pipe line through a user interface.

The pipe block joining inspection unit 120 extracts pipes that are coupled to pipes of different blocks from the received pipe diagrams, and checks whether each of the extracted pipes satisfies the pipe block joining criteria.

In one embodiment, the pipe block joining inspection unit 120 may sequentially extract the pipes 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 pipe block joining inspection unit 120 determines whether each of the extracted pipes corresponds to a pipe joining with a pipe of another block. If the extracted pipe corresponds to a pipe joining with another pipe, have.

For example, it is possible to additionally add codes that can be distinguished from other pipes to pipes that are associated with other blocks at the time of design, and the pipe block joining inspection unit selects the pipes based on the additional code, You can decide.

In one embodiment, the pipe block joining inspection unit 120 may check whether the extracted pipe has an inspection history, and determine a pipe having no inspection history as a pipe block joining inspection target. Here, the inspection history corresponds to a past inspection result in which a pipe block joining inspection is performed for a specific pipe and a modification or adjustment to the pipe is performed according to a pipe block joining reference violation.

Accordingly, the pipe block joining inspection unit 120 can exclude duplicate inspection of the pipes having an inspection history and need no inspection of the production rule, or even if the pipe violates the production rule, , A specially-manufactured pipe), the computer-implemented device 100 can perform a rapid pipe-block joining inspection.

In one embodiment, the pipe block joining checker 120 can check whether the extracted pipes or each of the pipes determined to be inspected satisfy the pipe block joining criterion.

Hereinafter, a process of inspecting the pipe-block coupling with respect to the pipe confirming whether or not the pipe-block coupling criterion and the pipe-coupling criterion for the pipe are satisfied will be described in detail.

In one embodiment, the plurality of pipe block engagement criteria may include a position reference that represents the shape reference of the head or tail of the joinable pipe, a Spec Cross reference that represents the specification reference of the joinable fitting, Lt; RTI ID = 0.0 > and / or < / RTI > order criteria.

FIG. 5 is an exemplary view showing a result of inspection of the position reference in the pipe block coupling reference.

Referring to FIG. 5, the position reference corresponds to a criterion for determining whether the shape of the head or tail of the pipe corresponds to a shape that can be combined with another pipe.

More specifically, the pipe block joining inspection unit 120 checks whether each head or tail portion, to which the first pipe to be inspected and the second pipes connected thereto are coupled, is a flange and the distance between the flanges is 10 mm or more Can be confirmed. In the case where one side of the first and second pipes is realized as a sleeve, the pipe block joining inspection unit 120 can check whether the distance between the pipes is 50 mm or more.

For example, if the distance between the flanges and the pipes is 5 mm on both sides of the first and second pipes, the pipe block joining inspection unit 120 can judge that the position criterion is not satisfied, and [Dist error -normal] And a detail message such as [Dist 11.1 is longer than 10] that the distance should be 10 mm or more can be generated.

For example, if both sides of the first and second pipes are implemented as sleeves, and the distance between both sides is 40 mm, the pipe block joining inspection unit 120 outputs an error message and a detailed message respectively [Dist error -One of both is slee], and [dist 11.1 is longer than 50].

The 3D pipe image shown in the lower part of FIG. 5 corresponds to the image output from the output unit 130 when the input unit 110 receives the selection information for the pipe through the inspection result, It is possible to output an image including the installed position of the pipe and adjacent pipes or output only the image of the pipe independently. The output of such a 3D pipe image can be equally provided in inspection results by other pipe block coupling criteria.

The specification cross reference corresponds to a criterion for judging whether or not the specifications between the fittings are matched. More specifically, the spec cross reference corresponds to a criterion for determining whether or not the specifications (e.g., pressure, diameter, etc.) of the first and second pipes match.

For example, when the diameters of the first and second pipes correspond to 250 mm and 350 mm, the pipe block joining inspection unit 120 can judge that the specification cross standard is not satisfied and the error such as [Spec is difference] Message and a detailed message such as [cDia is 250, cmpDia is 350].

The coupling criterion corresponds to an inspection item for judging whether or not the connecting portions of the first and second pipes are 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 located between the two portions, 2 pipe can be judged as not satisfying the coupling criterion by confirming that the connection relation of the pipe is composed of flange + gasket. At this time, the pipe block joining inspection unit 120 can generate an error message such as [Flan + Gask + Flan Rule Violation].

In one embodiment, the pipe block joining checker 120 may generate an inspection record that pairs the pipe that does not meet the pipe block joining criterion and the corresponding pipe block joining criterion.

For example, if the particular pipe A does not satisfy the position criteria, the pipe block joining checker 120 may generate an inspection record that pairs the pipe A and the position reference, and more specifically, Lt; RTI ID = 0.0 > B < / RTI >

The output unit 130 outputs the result of the pipe block combination check to the display.

In one embodiment, the output unit 130 may output the shapes of the selected pipe and at least one of the adjacent pipes to the 3D image based on the pipe diagram, when the user selects a specific pipe from the inspection result. In addition, the output unit 130 can independently output only the 3D image of the selected pipe to the display.

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

The database 140 stores pipe diagrams and pipe block joining criteria, and provides specific pipe diagrams and pipe block joining criteria to the pipe block joining inspection unit 120 under the control of the control unit.

In one embodiment, the database 140 may store the inspection records generated by the pipe block binding inspection unit 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 pipe block joining criteria have a reference value for each defined pipe. In some cases, the user can input a temporary reference value.

The control unit 150 controls data flow between the input unit 110, the pipe block coupling check 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 block connection 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.

2 is a flowchart illustrating a pipe-block joining inspection method.

Referring to FIG. 2, the computer-executable apparatus 100 provides a user interface through which a user can select a pipe diagram through the input unit 110 (S210).

Upon receiving the selection information of the user, the input unit 110 selects at least one second pipe line to be connected to the first pipe line and the first pipe line to be inspected at step S220.

In one embodiment, the input unit 110 may select a range of each of the first and second pipelines in a block unit through a position controller that selects a key-in or a plurality of positions.

The computer execution device 100 receives the pipe diagram from the database according to the user's selection (S230).

In one embodiment, the computer-implemented device 100 may receive the selected pipe diagram from an external database via the Internet (not shown).

The control unit 150 may control the database 140 to provide the pipe block joining inspection unit 120 with the corresponding pipe diagram and pipe block joining criteria.

The pipe block joining inspection unit 120 extracts the pipes from the received pipe line, respectively (S240).

In one embodiment, the pipe block joining inspection unit 120 may check whether the extracted pipe has an inspection history, and determine a pipe having no inspection history as a pipe block joining inspection target.

The pipe block joining inspection unit 120 checks whether each of the extracted pipes satisfies the pipe block joining criteria (S250).

If the pipe does not satisfy at least one of the selected pipe block coupling criteria, the pipe block coupling checking unit 120 generates a check result including the pipe and the pipe block coupling criterion in operation S260.

In one embodiment, the pipe block joining inspection unit 120 determines whether or not the specific pipe includes an error message indicating that the specified pipe does not satisfy the specified pipe block joining criterion, and a concrete detailed message including the pipe information and reference information Can be generated and included in the test results.

The pipe block joining inspection unit 120 sequentially checks whether the pipe satisfies all of the pipe block joining criteria.

When the pipe block binding inspection for the specific pipe ends, the pipe block binding inspection unit 120 checks whether there is a pipe that has been extracted by the pipe block binding inspection unit 120 but has not been inspected yet (S270) The above steps (S250 to S270) are repeatedly performed until the pipe-block joining inspection is performed on the pipes.

If the pipe block connection check of all extracted pipes is successfully performed, the output unit 130 outputs the inspection result generated by the pipe block connection inspection unit 120 to the display (S280).

The user can recognize the problem of the pipe based on the inspection result and solve the problem.

In one embodiment, when a particular pipe is selected from the inspection results, the output unit 130 may output the shapes of the selected pipe and at least one pipe adjacent to the selected pipe to the 3D image based on the selected pipe diagram.

This allows the user to more easily recognize the problem with the pipe.
