Description

  The present invention relates to a system for assigning attribute data to a CAD model of a plant and apparatus.

  In plant design work, it is common to introduce a system that utilizes 3D CAD as CAD. In addition, the created 3D model has been used not only for design work but also for construction plans and maintenance plans.

  At that time, it is necessary to associate the 3D model of the plant with the construction process and the maintenance work. However, since the number of parts of the plant is very large, the associating operation has been a big problem.

  As a prior art for these measures, in Patent Document 1, “A 3D model of each construction member included in the construction is created by the CAD program, and a construction construction plan is created by the process planning program. The layer in which the 3D model is drawn is associated with each type of work included in the created construction plan, and information specifying the layer associated with each type of work is given to the CAD program 10 ”.

  According to Patent Document 1, when any one of the 3D model of the member and the process procedure is changed, the association for reflecting the change on the 3D display of the construction status without changing the other Is possible.

  In addition, as other prior art, Patent Document 2 states that “in a plant construction simulation data creation method for creating a construction plan using a scheduling system and a CAD system, an operation managed by the scheduling system and an object of the operation” In this case, the parts managed by the CAD system are associated with each other, and when the work is divided into a plurality of subordinate works constituting the work, a process of associating the parts with each of the subordinate works is performed. It is characterized.

  As a result, when the upper construction work (or plant part) is expanded (detailed) to the lower work (or plant part), it becomes possible to cope with the plant part (or construction work) in parallel. Therefore, the association can be performed effectively.

JP 2001-249985 A JP 2009-169778 A

  However, for example, when considering the correspondence between plant parts and the construction process, it may be desired to associate a part of the parts belonging to a certain layer with the construction process. Further, when it is desired to associate a part not only with a construction process but also with a maintenance procedure, for example, the unit of association differs from the construction plan. In such a case, it is difficult to associate plant parts in units of layers by the method described in Patent Document 1.

  Further, regarding Patent Document 2, when performing a task of refining an upper part to a lower part, it is efficient because the parts can be associated with processes at the same time, but has already been detailed. In addition, when the 3D model is associated with a process, it is difficult to apply the present technology.

  In view of the above, an object of the present invention is to provide a plant information data providing system that can easily and intuitively associate various related tasks such as construction processes and maintenance procedures with a 3D model of a plant.

  The present invention for solving the above-described problems is a plant data providing system including an operation unit, a storage unit, and a display unit for associating attribute information of a CAD model of a plant created by CAD with a work process of the plant. The display unit includes a first display unit that displays the CAD model, a second display unit that displays an attribute information definition area in which the attribute information of the work process is defined, and a third display unit that displays the model. The storage unit includes at least attribute information of the CAD model of the plant and an attribute information addition rule associated with the attribute information definition area, and the arithmetic unit is a CAD model displayed on the first display unit by the user. And the attribute information definition area displayed on the second display unit, the attribute information of the plant work process and the CAD model according to the attribute information addition rule. And forming a new attribute information by the attribute information.

  According to the present invention, various related tasks such as a construction process and a maintenance procedure can be easily and intuitively associated with a 3D model of a plant, and a construction system for a plant task can be easily constructed.

  Embodiments of the present invention will be described below with reference to the drawings.

  In the present invention, attribute information relating to, for example, a process of a construction plan is added to the information of a 3D model of a plant created by 3D CAD.

  The plant data providing system according to the first embodiment illustrated in FIG. 1 is configured by a computer system such as 3D CAD, and includes a storage unit DB, a calculation unit C, a display unit DP, an input / output unit, and the like.

  In FIG. 1, the display unit DP includes a CAD model display unit DP1, an attribute information definition area display unit DP2, and a model display unit DP3. These display units DP1, DP2, and DP3 constitute a display screen on a monitor display that is the display unit DP.

  The calculation unit C includes an attribute information adding unit 4, a 3D model display control unit 7, and the like. The storage unit DB includes a plant database 5 and a storage unit 3 for attribute information addition rules.

  FIG. 2 shows a configuration example of the display screens DP1, DP2, and DP3 in the display unit DP. As the display screen, three screens (DP1, DP2, DP3) may be displayed at the same time, individual screens may be displayed individually, or an appropriate combination screen may be displayed. In addition, screens other than the display screens DP1, DP2, and DP3 may be displayed. FIG. 2 shows a case where three screens are displayed simultaneously.

  When the user selects a plant name from the file button BF in FIG. 2 on the display unit DP of the plant data providing system in FIG. 2, a 3D model of the plant created by 3D CAD is displayed on the CAD model display screen DP1. The 3D model may represent the entire configuration of the plant, but here, the piping configuration of FIG. 3 is displayed as an illustrative example. The CAD model in the explanation example is a 3D model M such as a pipe, a steel frame, or a device. In addition, the display part DP of the plant data provision system of FIG. 2 includes a customize button BC described later in addition to the file button BF.

  The 3D model M in FIG. 3 includes a plurality of models such as four straight pipe models (part names are A, B1, B2, and C), two bend models (part names are A and B), and a virtual on-site weld line model. It is composed of These individual models are defined as diameters (thicknesses), wall thicknesses, lengths, radii of curvature, materials, and the like, and are configured as 3D models that also include 3D information of installation positions after assembly.

  Parts such as individual pipes represented by these models are handled in spool units SP when they are brought into the plant construction site. For example, the straight pipe A, the bend A, and the straight pipe B1 are welded in advance at the factory, and are transported to the plant construction site as the spool SP1. Similarly, the straight pipe B2, the bend B, and the straight pipe C are carried to the plant construction site as a spool SP2. Thereafter, the spool SP1 and the spool SP2 are welded according to the local weld line model.

  In addition, as shown in FIG. 4, three attributes of a line No, a spool No, and a part No are assigned to the parts such as individual pipes represented by these models. According to the table of FIG. 4, straight pipe A, bend A, straight pipe B1, welding line, straight pipe B2, bend B, and straight pipe C are part names, and these are designated as part numbers P1, B1, P2, respectively. , FW1, P3, B2, and P4. In the line No column, Line 01, which is the same line number, is assigned, so that it is understood that these parts are parts used on the same line. Further, the same spool No (SP1) is stored in the straight pipe A, the bend A, and the straight pipe B1, and the same spool No (SP2) is stored in the straight pipe B2, the bend B, and the straight pipe C. It can be understood that these are handled as one transport unit.

  These three attributes of line No, spool No, and part No are attributes (model attributes) assigned to the 3D model M. These attributes are given by the model design at the plant construction design stage.

  The information of the 3D model including the 3D information described above and the attribute information of the 3D model illustrated in FIG. 4 are stored in the database 5 of FIG. It is used for display in the DP and is stored in the database 5 of FIG. 1 together with the intermediate product and the result product generated as a result.

  FIG. 5 shows a state where the 3D model M is displayed on the display screen DP1 when the file button BF is operated in the screen configuration of FIG. On this screen, the user then operates the customize button BC, and operates the construction process button BC1 from the expanded menu.

  FIG. 6 shows a display screen DP when the construction process button BC1 is operated. At this time, the construction process is displayed on the display screen DP2 while the 3D model M is displayed on the display screen DP1. Here, the horizontal axis of the display screen DP2 takes time, and the frames 20a, 20b, and 20n from the work process A, the work process B to the work process N are displayed in time series in the vertical direction. The square frame is an area (attribute information definition area) meaning that it is a work process of a construction plan.

  At this stage, the work contents that are the contents of the work process N from the work process A and the work process B are not specified. Only a plurality of work process displays are sequentially displayed as work schedules. The contents in each work process are determined by subsequent operations.

  In the display state of FIG. 6, the user operates the button BC2 for giving attribute information from the expanded menu. Then, the 3D model M displayed on the display screen DP1 is selected and dragged and dropped into the frame 20a of the work process A displayed on the display screen DP2. Here, the act of selecting and dragging and dropping is basically the action of associating the 3D model M with the frame of the work process A, and if it can be handled, the operation of other input means such as a mouse or a keyboard May be realized.

  Here, it is assumed that the piping model is selected by designating a range within the 3D model M by operating the mouse and selecting the entire piping model. The piping model selected in this case is the part name having the configuration and contents shown in FIGS. 3 and 4, and after the selection, it is identified and displayed on the screen so that the selected range can be understood. Shall.

  The selection method is not particularly limited, and when the 3D model is divided into layers, the 3D model may be selected by selecting the layer. Also, a part of the 3D model selected via the layer may be deselected by operating the mouse, or conversely, a 3D model of another layer may be additionally selected.

  The attribute information assigning means 4 in the operation unit C in FIG. 1 receives a series of screen operations by the user and follows the processing program described in the attribute information assignment rule 3 and relates to the attribute information definition area in a part of the CAD model. Perform the process of assigning attributes. The processing program described in the attribute information addition rule 3 is shown in FIG.

  In the attribute information addition rule 3 shown in FIG. 7, in the state where the attribute information addition button BC2 is operated and the 3D model M is selected, the work unit of the 3D model M is acquired in the first processing step S1.

  Here, the work unit is a group that is handled as a group when performing construction work, and corresponds to a spool, a valve, a local weld line, and the like in the case of 3D model M piping. Therefore, when the 3D model M is selected by the user, in the specific example of the 3D model M of the piping in FIG. 3, the spool 1, the spool 2 and the field welding line 1 are obtained and handled as a unit as a unit. Will be. As shown in FIG. 4, in the work unit of the spool 1, the parts of the straight pipe A, the bend A, and the straight pipe B1 are objects of work, and in the spool 2, the parts of the straight pipe B2, the bend B, and the straight pipe C are working. It becomes the object of. The on-site weld line is a work unit for welding the spool 1 and the spool 2.

  In the next processing step S2, one of the work units is selected. Subsequently, in processing step S3, a name (work process number) obtained by connecting the selected work process name and work unit with a hyphen is given to the 3D model as an attribute. The selected work process name is the name of the work process given to the frame 20 to which the 3D model selected by dragging is dropped. The name of the work process is an attribute for the work process.

  For example, in the drop-destination display screen DP2, it is assumed that the frame of the selected attribute information definition area is the work process A, and the work process name assigned in advance to this is “Work A”. Also, assume that the first work unit of the 3D model M selected on the drop-source display screen DP1 is spool 1 (SP1).

  FIG. 8 is a diagram illustrating an example of a work process number that is a name obtained by connecting a work process name and a work unit with a hyphen. In this case, the attribute of the work process number is “WorkA_SP1” and “WorkA_SP2”. When the selected work unit is the weld line 1, the work process number is written as “WorkA_FW1”.

  Here, the work process number is stored in the database 5 in association with the aforementioned line number Line, spool number SP, and part number. Specifically, in the case of the work process number “WorkA_SP1,” Line01 is stored as the line number Line, SP1 is stored as the spool number SP, and P1, P2, and B1 are stored in association with each other. Similarly, in the case of the work process number “WorkA_SP2,” Line01 is stored as the line number Line, SP2 is stored as the spool number SP, and P3, P4, and B2 are stored in association with each other. In the case of the work process number “WorkA_FW” of the weld line, Line 01 is stored as the line number Line, there is no symmetry to the spool number SP, and FW1 is stored in association with the part number.

  As described above, the attribute information is defined (model attribute) for the CAD model of the display unit DP1, and the frame 20 in the attribute information definition area that represents the work process of the display unit DP2. Attributes are defined (attributes for work processes). By associating the model and the work process on the two display screens, a new attribute, a number with a new code, and a symbol system are formed by integrating information of each attribute. Thus, plant data can be attached by combining two different attributes.

  The new attribute information determined in this way is stored in the database 5. Depending on the type of CAD, the attribute information is directly assigned to the CAD model instead of the database 5. In this case, the obtained attribute information is not only stored in the database 5 but also stored in the CAD model. Is also granted.

  In process step S4, it is confirmed that the attribute assignment work of the work process number has been completed for all work units of the selected 3D model, and the process is continued until the work is completed.

  FIG. 9 is a diagram showing display screens DP2 and DP3 as display contents of the display unit DP after the work of assigning work process number attributes is completed. When the work process A is selected on the display screen DP2, information on the work process number for which the attribute assignment work has been completed is displayed on the display screen DP3 in a form expanded to the part number level. That is, the first line of the display screen DP3 shows the work process number and related attributes for the part number P1, and the second line shows the work process number and related attributes for the part number B1.

  In addition, in the process step S5 of FIG. 7, it is good to determine the information of work order further. When the 3D model is dragged and dropped in FIG. 6, the 3D model itself is generally a complicated configuration, and the determination of the work process of one 3D model can be completed by repeating the drag and drop operation several times. There are many scenes. In such a case, the user may grasp the order of the construction work and perform the operation. However, if possible, it is desirable that the user can perform without making the user aware of the order of the construction work.

  In processing step S5, the order between the models is determined in accordance with the construction order rule that the lower side or side of the building to be constructed is preferentially constructed, the order information is determined, and the final display screen The burden on the user is reduced by reflecting on the display of DP2.

  As described above, according to the present invention, the attribute is automatically given by the attribute information addition rule 3 by selecting the attribute information definition area 20 on the display screen DP2 while the CAD model is selected on the display screen DP1. Therefore, attributes can be assigned intuitively and efficiently.

  It should be noted that the attribute is assigned when the attribute definition area 20 is clicked (or dropped) only when the attribute information addition command of FIG. 5 is activated (attribute information addition button BC2 operation).

  Normally, when the attribute information definition area 20 on the display screen DP2 is clicked, a list of models with the attributes of the clicked area is displayed on the display screen DP3 (model display unit). For example, when “work process A” is clicked, a list of parts associated with work process A is displayed as a list as shown in FIG. However, items to which no attribute data is assigned cannot be displayed. Therefore, in the state where the model related to the work process B is not registered, even if the work process B is clicked, the model list is not displayed on the display screen DP3.

  In this embodiment, as shown in FIG. 9, a list of parts such as straight pipe A and bend A is displayed. However, as shown in FIG. 8, a list of units of work process numbers is displayed. You may do it. In this case, a plurality of part numbers included in the same spool SP may be displayed in the part number column.

  When one or more parts are selected on the list of the display screen DP3 (model display unit), the model display control means 7 in FIG. 1 selects the selected part from among the 3D model M on the display screen DP1. Make it appear light. Since the selection is performed in units of rows in the list, the highlight display can be controlled in units of parts in the list shown in FIG. 9, but when the work process number list shown in FIG. 8 is selected, in units of spools. The display will be controlled.

  Furthermore, the model display control means 7 can also change the display of the 3D model M in accordance with the information in the database 5. For example, if you make a model that has an attribute value for the work process number semi-transparent, models that are not associated with the construction process are displayed as usual, and those that are associated become translucent. Visualization of work is also possible.

  As described above, since the attribute is automatically assigned by the attribute information addition rule by selecting the attribute information definition area on the display screen DP2 with the CAD model selected on the display screen DP1, it is intuitive. And an attribute can be provided efficiently.

  In this embodiment, when the attribute information definition area is selected, the selected model is dragged and dropped into one of the attribute information definition areas 20. For example, when the model is selected, the attribute information definition area is clicked. The selection method is not limited to this method.

  Moreover, although the model created by 3D CAD of the plant was described as an example as the CAD model, the CAD model is not limited to the 3D model, and may be 2D CAD for creating a plant system diagram.

  Next, a second embodiment of the present invention will be described.

  The difference between the second embodiment and the first embodiment is the items displayed on the algorithm of the attribute information addition rule 3 and the model display section DP3.

  FIG. 10 shows an algorithm of the attribute information addition rule 3 according to the second embodiment. A different point from the algorithm of Example 1 is the algorithm of the part shown with the broken line. Since the processing from processing steps S1 to S3 is the same, the description thereof is omitted. By the processing so far, the work of assigning work process number attributes is executed, and the list of FIG. 8 or FIG. 9 is formed.

  In the processing step S6 added in the second embodiment, in the state in which the list of FIG. 8 or FIG. 9 is formed, the amount of work required for construction from the attribute information such as the size, position, outer diameter, and weight of the model. Calculate

  For example, when the selected unit of work is a pipe spool, a reference work amount is calculated from the length, outer diameter, and weight of the pipe. Qualitatively, the longer the pipe length, the larger the outer diameter, and the heavier the weight, the larger the work amount. Therefore, here, the standard work amount = A / pipe length + B / outer diameter + C / weight. The amount of work was calculated with the formula.

  A, B, and C are weighting coefficients, and different factors (length, diameter, weight) are converted into work amounts and converted accordingly. However, even if the piping length, outer diameter, and weight are exactly the same, when piping is installed with a crane, the working time varies depending on the type of piping system and the installation height. Therefore, in this embodiment, the work amount was calculated by correcting the reference work amount (adjusting the coefficients A, B, and C) according to the type of the piping system and the height at which the pipe is installed.

  In addition, when the selected unit of work is field welding, the welding work time per unit length can be estimated based on the thickness and material of the pipe, so the work amount was calculated from the estimated value and the outer diameter of the pipe.

  In the next processing step S7, it is determined whether the calculated total amount of work satisfies the limit value. For example, if there is a restriction of 400 [man-hour] as the work process A, it is determined whether the total of work assigned as the work process A is 400 or less.

  If the limit value is satisfied, the process proceeds to the next process step S4. If not satisfied, a warning message is displayed in process step S8, and the process is terminated.

  FIG. 11 shows a display content example of the model display unit DP3 of the second embodiment. The amount of work calculated by the algorithm of the attribute information addition rule 3 in FIG. 10 is added to the display item. In this example, when the work process numbers are “WorkA_SP1” and “WorkA_SP1”, a work volume of 5 [man-hour] is expected, and when the work process number is “WorkA_FW1”, the work volume of 3 [man-hour] is expected. This represents that a total of 13 [man-hour] is expected. Thereby, it can be confirmed which work takes time. Further, when each work is selected on the model display unit DP3, the display part DP1 of the corresponding CAD model is highlighted, so that the relationship between the work amount and the model can be intuitively confirmed.

  If the amount of work does not satisfy the limit value, it is necessary to modify the construction plan. In this way, it is possible to confirm how much work will be required for which piping work in both the list and the CAD model. Will also be easier.

  As described above, in this embodiment, the validity can be confirmed at the same time as the attribute information is given. In addition, when the attribute assignment is not appropriate, it can be easily corrected.

  In the present embodiment, the example of assigning attributes related to the construction work process using the screen of the construction plan has been described. However, the present invention is not limited to the work related to the construction work process. It is possible to assign attributes to work processes related to the entire life cycle, such as the work process, maintenance work process, and inspection route work process.
