[Technical Field]

[0001] The present invention relates to a unit processing system for creating design data such as manufacturing drawings for units. [Background technology]

[0002] At construction sites, the labor force is shrinking due to the aging of workers and a decline in the number of young people joining the workforce, so efforts are being made to produce various units to be installed on site off-site.In equipment construction at construction sites, units are often produced one by one to match the design and building, and unit planning also needs to be done for each site.In order to produce such units, it is first necessary to create construction drawings for on-site construction, and then create design data such as unit manufacturing drawings and necessary forms that match the construction drawings.

[0003] For example, the construction support method disclosed in Patent Document 1 includes a construction drawing acquisition step of acquiring construction drawings, a construction object BIM model creation step of creating a construction object BIM model based on the construction drawings, a processed part BIM model creation step based on processing drawings created based on the construction drawings, which has a processed shape information extraction step of extracting processed shape information for each of the multiple processed parts from the processing drawings, and an installation position information extraction step of extracting installation position information for each of the multiple processed parts within the construction object from the processing drawings, and an integrated BIM model creation step of creating an integrated BIM model by incorporating each of the multiple processed part BIM models into the construction object BIM model based on the processed shape information and installation position information.

[0004] [Patent Document 1] JP 2019-21190 A Summary of the Invention [Problem to be solved by the invention]

[0005] Creating unit fabrication drawings requires special techniques using computer-aided design (CAD), which requires several times the effort required to create construction drawings. Planning units that are tailored to the design and building requires many years of on-site experience, making it difficult for young on-site personnel to consider. Furthermore, with conventional unit planning methods, even if knowledge and skills from past unit planning cases are accumulated, they cannot be used for the one-off production of units that differ from past cases, making it difficult to carry out efficient unit planning.

[0006] The present invention has been made to solve the various problems mentioned above, and aims to provide a unit processing system that reduces the effort required for drawing units, moves away from unit drawing that is dependent on individual skills, proposes the best units for each site, improves customer satisfaction, and promotes the automation of unit drawing as a future construction model.

[0008] In the above-described unit processing system, the input means inputs the type of the unit, the pattern of the unit, and the model of the equipment used in the unit as the selection conditions, and the output means determines the template model to be output from the multiple types of units based on the input type of the unit, the pattern of the unit, and the model of the unit.

DETAILED DESCRIPTION OF THE INVENTION

[0011] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. First, a unit processing system 1 of this embodiment will be described with reference to Fig. 1. Fig. 1 is a block diagram showing the unit processing system 1.

[0012] The unit processing system 1 selects a unit to be the target of unit planning (unitization) from a plurality of types of units, and creates design data such as a production drawing and necessary forms suitable for the site for the selected unit.

[0013] For example, the unit processing system 1 includes a storage means for storing template models of multiple types of units, an input means for inputting and selecting selection conditions for units for unit planning (unitization), an output means for outputting a template model based on the input selection conditions, an editing means for editing a parameter file of the template model, and a drawing means for creating a production drawing of the unit based on the template model. In this embodiment, an example will be described in which the unit processing system 1 having the storage means, input means, output means, editing means, and drawing means is applied to a user terminal 2 of a user.

[0014] The user terminal 2 includes a control unit 10 configured with a computer such as a CPU, and the control unit 10 is connected to a storage unit 11 such as a ROM, RAM, hard disk drive, or flash memory, and a communication unit 12 that communicates with external devices. The control unit 10 is also connected to an operation unit 13 that accepts user operations, and a display unit 14 that displays various screens.

[0015] The storage unit 11 stores programs and data for controlling the various units and functions of the user terminal 2, and the control unit 10 controls the various units and functions of the user terminal 2 by executing arithmetic processing based on the programs and data stored in the storage unit 11. The communication unit 12 is connected to an external device via a network so as to be able to communicate with the external device.

[0016] For example, in this embodiment, the storage unit 11 operates as storage means of the unit processing system 1, and stores template models for each of a plurality of types of units, and stores the template model for each unit in association with selection conditions. The user terminal 2 can accept registration of a template model for a new unit or a unit planned by the user in the past, and store the template model in the storage unit 11.

[0017] The storage unit 11 also stores unit selection software 25, which is a program for selecting one unit from multiple types of units; that is, the user terminal 2 is equipped with the unit selection software 25. The unit selection software 25 operates as input means and output means of the unit processing system 1. The control unit 10 operates as a selection condition input unit 20 and a template model output unit 21 by executing the unit selection software 25 in response to user operations. In other words, the control unit 10 executes the selection condition input unit 20 and the template model output unit 21 in the unit selection software 25.

[0018] The storage unit 11 stores parameter editing software 26, such as spreadsheet software, which is a program for editing a parameter file of a template model; that is, the user terminal 2 is equipped with the parameter editing software 26. The parameter editing software 26 operates as editing means of the unit processing system 1. The control unit 10 operates as a parameter editing unit 22 by executing the parameter editing software 26 in response to user operations. In other words, the control unit 10 executes the parameter editing unit 22 in the parameter editing software 26.

[0019] The storage unit 11 stores computer-aided design (CAD) software 27, which is a program for creating a manufacturing drawing of a unit based on a template model; that is, the user terminal 2 is equipped with the CAD software 27. The CAD software 27 operates as a drawing means of the unit processing system 1. The control unit 10 operates as the CAD software 27 in response to a user operation, thereby functioning as the CAD unit 23. In other words, the control unit 10 executes the CAD software 27 to execute the CAD unit 23.

[0020] Specifically, the memory unit 11 stores template models for multiple types of units, such as an "S-class earthquake-resistant frame," a "horizontal chilled / hot water unit," and a "bispia frame." The memory unit 11 also stores template models for one or more structural types for each unit. The template models stored in the memory unit 11 each have different unit targets and structural types. For ease of explanation, units with different unit targets and structural types are hereinafter referred to as "different types of units." The memory unit 11 may also store template models for multiple unit targets, such as a "refrigerant standpipe unit," an "air-cooled chiller-related unit," an "outdoor unit," a "steel pipe standpipe post-installation unit," a "plate heat exchanger unit," a "once-through boiler unit," a "return tank-related unit," an "oil service tank-related unit," a "shell-and-tube-related unit," and a "cooling tower-related unit."

[0021] The selection conditions associated with the template model of each unit include a plurality of selection conditions such as "major classification," "medium classification," "minor classification," etc. That is, a unit is selected by selecting a "major classification," "medium classification," or "minor classification."

[0022] The selection conditions for "major category" are used to select the unit to be planned (unitized) from multiple unit targets such as "S-class earthquake-resistant frame," "horizontal cold and hot water unit," and "Bispyre frame." The selection conditions for "medium category" are used to select the unit pattern to be planned from multiple patterns of unit targets selected in "major category" as the unit structural type. The selection conditions for "minor category" are used to select the type of equipment to be planned from multiple types of equipment used in units consisting of the unit target selected in "major category" and the pattern selected in "medium category" as the unit structural type.

[0023] For example, when the "major category" is a "refrigerant standpipe unit," the number of pipe rows is selected as the "medium category," and there are no selection conditions for the "minor category." When the "major category" is an "air-cooled chiller-related unit," the manufacturer name is selected as the "medium category," and the chiller model is selected as the "minor category." When the "major category" is an "outdoor unit," the manufacturer name is selected as the "medium category," and the outdoor unit model is selected as the "minor category." When the "major category" is a "steel pipe standpipe post-installation unit," the number of pipe rows is selected as the "medium category," and there are no selection conditions for the "minor category." When the "major category" is a "plate heat exchanger unit," the form is selected as the "medium category," and the heat exchanger model is selected as the "minor category." When the "major category" is a "once-through boiler unit," the manufacturer name is selected as the "medium category," and the once-through boiler model is selected as the "minor category." When the "major category" is a "return tank-related unit," the form is selected as the "medium category," and the return tank model is selected as the "minor category." If the "major category" is "oil service tank surrounding unit", the shape is selected as the "medium category" and the model of the oil service tank is selected as the "minor category". If the "major category" is "shell and tube surrounding unit", the manufacturer name is selected as the "medium category" and the model of the shell and tube is selected as the "minor category". If the "major category" is "cooling tower surrounding unit", the shape is selected as the "medium category" and the model of the cooling tower is selected as the "minor category".

[0024] The storage unit 11 stores, as template models for each unit, for example, a template parameter file in which various parameters of the unit can be edited, and a template 3D model file in which a 3D model of the unit can be output. The various parameter items of the unit may differ for each type of unit, or units of two or more structural types that have a common unit target may have common items.

[0025] The template parameter file can be executed by the parameter editing software 26 to display various parameters, and a parameter file obtained by duplicating the template parameter file can be executed by the parameter editing software 26 to display and edit various parameters. The template parameter file contains multiple editable parameters and further includes a calculation program that can calculate necessary information based on the parameters. For example, the template parameter file includes a calculation program for automatic calculation formulas required for various calculation reports such as seismic resistance calculation, strength calculation, and anchor calculation report. In this embodiment, the file before editing is referred to as the template parameter file, and the file after editing is referred to as the parameter file. The template parameter file stores preset initial values ​​for each parameter, and the initial values ​​for necessary information are calculated by a calculation program based on the initial values ​​of each parameter.

[0026] The template parameter file for the "S-class seismic pedestal" includes multiple parameters, such as "distance from the upper floor surface to the lower floor ceiling (H1)," "distance from the upper floor floor surface to the underside of the primary steel member (H2)," "distance from the underside of the equipment to the lower floor ceiling (H3)," "distance from the underside of the frame to the lower floor ceiling (H4)," "equipment height," "frame height (H)," "equipment suspension bolt width," "suspension column width (S)," "KH (design horizontal seismic coefficient)," and "KV (design vertical seismic coefficient)." Furthermore, the template parameter file for the "S-class seismic pedestal" includes a calculation program that performs weight calculations based on the parameters.

[0027] The template parameter file for the "horizontal chilled / hot water unit" includes, for example, for each piping stage of the "horizontal chilled / hot water unit," parameters such as "material setting for each fluid type," "vertical reference pipe," "maximum main pipe diameter for the unit group," "maximum branch pipe diameter for the unit group," "upward extraction," "downward extraction," "left-side suspension screw offset," "right-side suspension screw offset," "distance between suspension screws," and "settings for up to eight pipes and offset value." The template parameter file for the "horizontal chilled / hot water unit" also includes parameters such as "type," "fluid type," "fluid type label," "flow direction," "material," "size," "maximum size of this pipe," "connection type," "pipe end component placement instructions," "pipe length," "branch extraction availability," "downstream size," "branch pipe (up to two) size," and "exit direction" for each pipe. The template parameter file for the "horizontal chilled / hot water unit" also includes a calculation program for calculating the full and dry weights of the pipes alone based on the parameters.

[0028] The template parameter file for the "Bispier Frame" includes multiple parameters, such as "suspension height (H)," "width (rW)," "height (rH)," "return chamber side suspension position (rP)," "supply chamber," "width (sW)," "height (sH)," "supply chamber side suspension position (sP)," "return side suspension bolt offset (rB)," "supply side suspension bolt offset (sB)," "return chamber removal setting," and "supply chamber removal setting." Furthermore, the template parameter file for the "Bispier Frame" includes a calculation program that creates an order form for the "Bispier Frame" based on the parameters, and a calculation program that calculates the angle of the suspension bolt brace and checks its validity.

[0029] The template 3D model file can be executed by the CAD software 27 to display a 3D model, and a 3D model file obtained by duplicating the template 3D model file can be executed by the CAD software 27 to display and deform a 3D model. For example, the CAD software 27 reads the parameter file of one unit and executes the template 3D model file of the one unit, thereby applying the parameters contained in the parameter file to the one unit and deforming the 3D model. In this embodiment, the file before deformation is referred to as the template 3D model file, and the file after deformation is referred to as the 3D model file.

[0030] In the unit selection software 25, the selection condition input unit 20 accepts the selection input of selection conditions by the user, and in this embodiment, as shown in Fig. 2, a unit processing screen 30 for accepting the selection input of selection conditions is displayed on the display unit 14. The unit processing screen 30 has, for example, a selection condition area 31, a preview area 32, a unit name area 33, a version area 34, and an open button 35.

[0031] The selection condition area 31 is an area that displays the selection conditions for units in a selectable manner. The selection condition area 31 has a major category selection section 31a for selecting the selection conditions for the "major category," a middle category selection section 31b for selecting the selection conditions for the "middle category," and a minor category selection section 31c for selecting the selection conditions for the "minor category."

[0032] The major category selection section 31a is composed of a list such as a drop-down list that lists multiple unit targets, and allows the selection of one unit target from among the multiple unit targets. The medium category selection section 31b is composed of a list such as a drop-down list that lists multiple patterns of the unit targets selected in the major category selection section 31a, and allows the selection of one pattern from among the multiple patterns. The minor category selection section 31c is composed of a list such as a drop-down list that lists multiple models of equipment used in units consisting of the unit targets selected in the major category selection section 31a and the patterns selected in the medium category selection section 31b, and allows the selection of one model from among the multiple models.

[0033] The preview area 32 displays a preview (rough shape) such as a perspective view of the unit selected in the selection condition area 31. The preview area 32 may also accept rotation and zoom operations for the preview of the displayed unit.

[0034] For example, when "S-class earthquake-resistant mounting frame" is selected in the major category selection section 31a of the selection condition area 31, the preview area 32 changes the outline shape of the "S-class earthquake-resistant mounting frame" depending on the type of equipment suspended from the earthquake-resistant mounting frame. Note that the preview area 32 displays a preview of the "S-class earthquake-resistant mounting frame" when a model is selected in the minor category selection section 31c.

[0035] For example, when a "horizontal cold / hot water unit" is selected in the major category selection section 31a of the selection condition area 31, the preview area 32 changes and displays the general shape of the "horizontal cold / hot water unit" depending on the number of piping stages (for example, 1 to 2 stages), since a "horizontal cold / hot water unit" has 8 pipes arranged per stage.

[0036] The unit name area 33 is an area that displays and allows the input of the unit name of the unit selected on the unit processing screen 30. The selection condition input unit 20 may set, as the initial value of the unit name, a name that combines the names of the selection conditions selected in the selection condition area 31, and may insert a predetermined symbol (for example, an underscore) between the names of the selection conditions. The selection condition input unit 20 first displays the initial value of the unit name in the unit name area 33, and then makes the unit name editable in the unit name area 33.

[0037] The version area 34 is an area that displays selectable versions of the CAD software 27 that executes the three-dimensional model file of the unit selected on the unit processing screen 30. The version area 34 is configured as a list such as a drop-down list, and allows selection of one version from among multiple versions of the CAD software 27. Alternatively, the version area 34 may allow selection of the CAD software 27 that executes the three-dimensional model file from among multiple types of CAD software 27.

[0038] The open button 35 is displayed so that it can be pressed to confirm the selection condition selected in the selection condition area 31 and the unit name entered in the unit name area 33. In response to the pressing of the open button 35, the selection condition input unit 20 confirms the selection condition selected in the selection condition area 31 and the unit name entered in the unit name area 33.

[0039] In unit selection software 25, template model output unit 21 duplicates a template parameter file and a template 3D model file of a template model of a unit that satisfies the selection conditions confirmed by selection condition input unit 20, and outputs a parameter file and a 3D model file with the confirmed unit name. Template model output unit 21 stores the duplicated parameter file and 3D model file in the same folder in storage unit 11. Note that template model output unit 21 may preset a folder for storing the parameter file and the 3D model file, or may display a folder selection screen on display unit 14 that accepts a selection operation for that folder in response to a press of open button 35.

[0040] When outputting the copied parameter file, the template model output unit 21 may start the parameter editing software 26 by using an API (Application Programming Interface) to execute the parameter file.

[0041] Furthermore, when outputting the copied three-dimensional model file, the template model output unit 21 may start the CAD software 27 by using the API to execute the three-dimensional model file.

[0042] In the parameter editing software 26, the parameter editing unit 22 executes the parameter file copied from the template parameter file in the template model output unit 21 using the API as described above or in response to a user operation. In this embodiment, as shown in FIGS. 3 to 7, the parameter editing unit 22 displays a parameter editing screen 40 on the display unit 14, which allows the parameters included in the parameter file to be displayed and edited. The parameter editing screen 40 has, for example, a parameter display area 41 and a preview area 42.

[0043] The parameter display area 41 is an area that displays a list of parameters in the parameter file and accepts parameter editing. Note that there are non-editable and editable parameters, and the parameter display area 41 displays non-editable parameters as non-editable and editable parameters as editable. Furthermore, the parameter editing unit 22 executes a calculation program included in the parameter file and displays the calculation results for the corresponding parameters in the parameter display area 41.

[0044] The preview area 42 displays a drawing of the unit (front view, rear view, top view, side view, etc.) showing the location of the parameters, and also displays the location of the parameters in the unit using dimension lines, etc. on the drawing.

[0045] For example, Figure 3 shows a parameter editing screen 40 for an "S-class earthquake-resistant mounting system." In the case of a parameter file for an "S-class earthquake-resistant mounting system," if the model of equipment that corresponds to the "S-class earthquake-resistant mounting system" has been determined, the parameters for the "S-class earthquake-resistant mounting system" include parameters that cannot be edited because they depend on the external shape and dimensions of the equipment. Here, the parameter display area 41 displays the parameters that depend on the external shape and dimensions of the equipment in an uneditable manner.

[0046] FIG. 4 also shows a parameter editing screen 40 for a "horizontal chilled / hot water unit." In the case of a parameter file for a "horizontal chilled / hot water unit," the parameter display area 41 includes a piping layout diagram for each stage, a general parameter area for displaying and editing general parameters common to each stage, a stage parameter area for displaying and editing stage parameters that can be set for each stage, and a piping parameter area for displaying and editing piping parameters that can be set for each pipe. The parameter editing unit 22 uses a calculation program to calculate the weight of the "horizontal chilled / hot water unit" when filled with water, including the steel, and the total weight, depending on the type of piping. This allows the necessary steel type to be automatically selected. Selecting the fluid type for the "horizontal chilled / hot water unit" specifies the type of piping to be used, and the parameter editing unit 22 narrows down the options for the pipe diameter, pipe weight, and connection type.

[0047] 5 to 7 show the parameter editing screen 40 of "Vispier Frame." In the case of a parameter file of "Vispier Frame," the parameter editing screen 40 has a sheet shown in FIG. 5 consisting of a parameter display area 41 and a preview area 42 for editing parameters, a sheet shown in FIG. 6 for printing out an order table based on the parameters, and a sheet shown in FIG. 7 for printing out a parameter table of related chambers. The parameter editing unit 22 can print out the order table sheet and chamber parameter table sheet on the parameter editing screen 40 as necessary forms or output them as electronic data such as PDF.

[0048] In the CAD software 27, the aided design unit 23 reads a parameter file that has been copied from a template parameter file by the template model output unit 21 or edited by the parameter editing unit 22 using the API or in response to a user operation as described above, and executes a three-dimensional model file that has been copied from a template three-dimensional model file by the template model output unit 21. Note that the parameter file and the three-dimensional model file used in the CAD software 27 are stored in the same folder as described above. The aided design unit 23 may further use a copied parameter file as the parameter file.

[0049] In this embodiment, as shown in Figs. 8 to 13, the support design unit 23 displays an support design screen 50 on the display unit 14, which displays a three-dimensional model created based on the parameter file and the three-dimensional model file. The support design screen 50 may not only display the three-dimensional model, but also enable deformation. Furthermore, the support design unit 23 can also save the three-dimensional model created based on the parameter file and the three-dimensional model file as a new three-dimensional model file.

[0050] Specifically, the assisted design unit 23 reads parameters required for the three-dimensional model file from the parameter file and inputs values ​​into parameters with the same names in the three-dimensional model file. As a result, the assisted design unit 23 performs parametric transformation on the three-dimensional model in the three-dimensional model file according to the parameters in the parameter file. The assisted design unit 23 has predefined transformation rules and performs parametric transformation on the three-dimensional model within the scope of the transformation rules. In the parametric transformation, the assisted design unit 23 may restrict dimensions such as length, width, and thickness, and weight in accordance with the transformation rules. In the parametric transformation, the assisted design unit 23 may also change not only dimensions and weight, but also part shapes, the number of supporting parts and fastening parts, the required steel materials, and piping spacing in accordance with the transformation rules. For example, as dimensions and weight increase due to parametric transformation, parts may be replaced with stronger ones, or the number of supporting parts and fastening parts may be increased.

[0051] The supportive design unit 23 can lay out a three-dimensional model of a unit on a sheet constructed with three-dimensional drawings as a production drawing, and can also lay out two-dimensional drawings of the unit (front view, back view, top view, side view, etc.) on a sheet constructed with the unit, and can further place associated dimension lines on the two-dimensional drawings. When transforming a three-dimensional model based on a parameter file and a three-dimensional model file, the supportive design unit 23 changes the size of the three-dimensional model laid out on the three-dimensional drawing or two-dimensional drawing, and changes the dimension lines accordingly. The supportive design unit 23 displays a sheet on which the three-dimensional model is laid out on the three-dimensional drawing or two-dimensional drawing on the supportive design screen 50. The supportive design unit 23 can switch between displaying three-dimensional drawings and two-dimensional drawings in response to a user operation.

[0052] If the unit is an "S-class earthquake-resistant mounting base," the support design unit 23 displays a sheet on the support design screen 50 in which a three-dimensional model of the "S-class earthquake-resistant mounting base" is laid out in a three-dimensional drawing, as shown in FIG. 8, and also displays a sheet on the support design screen 50 in which a three-dimensional model of the "S-class earthquake-resistant mounting base" is laid out in a two-dimensional drawing, as shown in FIG. 9.

[0053] If the unit is a "horizontal cold / hot water unit," the support design unit 23 displays a sheet on the support design screen 50 in which a three-dimensional model of the "horizontal cold / hot water unit" is laid out in a three-dimensional drawing, as shown in Figure 10, and also displays a sheet on the support design screen 50 in which a three-dimensional model of the "horizontal cold / hot water unit" is laid out in a two-dimensional drawing, as shown in Figure 11.

[0054] If the unit is a "Bispyre Frame," the support design unit 23 displays a sheet on the support design screen 50 in which a three-dimensional model of the "Bispyre Frame" is laid out in a three-dimensional drawing, as shown in FIG. 12, and also displays a sheet on the support design screen 50 in which a three-dimensional model of the "Bispyre Frame" is laid out in a two-dimensional drawing, as shown in FIG. 13.

[0055] If the unit is a "Bispyre Frame," the sheet on which the three-dimensional model is laid out on a three-dimensional drawing is used for confirmation. If the unit is an "S-class earthquake-resistant frame" or a "horizontal hot and cold water unit," the sheet on which the three-dimensional model is laid out on a three-dimensional drawing is framed, and the support design department 23 can print out the sheet or output it as electronic data such as PDF as a necessary document to create an order drawing for the manufacturer.

[0056] The support design unit 23 can use the three-dimensional model based on the parameter file and the three-dimensional model file as a construction model as is. In addition, the support design unit 23 can also output the three-dimensional model based on the parameter file and the three-dimensional model file as a separate equipment CAD model using an output function provided by the vendor.

[0057] In addition, when the unit is an "S-class earthquake-resistant frame," the support design unit 23 selects L-shaped steel or C-shaped steel as the support part depending on the total weight, which is the sum of the weight of the piping when full of water and the calculated frame weight, when calculating the shape of the three-dimensional model based on the parameters.

[0058] Furthermore, if the unit is a "horizontal chilled / hot water unit," the support design unit 23 calculates the minimum distance between the upper and lower tiers based on the parameters if the piping has two or more tiers, and verifies the validity of the distance between the upper and lower tiers input by the user. The support design unit 23 generates straight pipes and joints required for the piping according to the coordinate points of the piping route and joints calculated based on the parameters.

[0059] As described above, the unit processing system 1 according to this embodiment includes the memory unit 11, which is a storage means for storing template models of multiple types of units in association with the selection conditions for each unit; the selection condition input unit 20, which is an input means for accepting input of unit selection conditions; the template model output unit 21, which is an output means for outputting a parameter file and a three-dimensional model file corresponding to a template model that satisfies the input selection conditions; parameter editing software 26, which is an editing means for accepting editing of the output parameter file; and computer-aided design (CAD) software 27, which is a drawing means for creating production drawings for units based on the parameter file and the three-dimensional model file.

[0060] With this configuration, the unit processing system 1 of the present invention allows the user to appropriately acquire a template model of a unit that is the target of unit planning (unitization) from template models of multiple types of units. Furthermore, by editing the parameter file of the template model to suit the site, the user can transform the 3D model shown in the 3D model file of the template model to suit the site. This allows the user to easily create design data for the unit, such as shop drawings and necessary forms, that suit the site.

[0061] Furthermore, with the unit processing system 1 of the present invention, unit manufacturing drawings can be created in the back office without preparing on-site working drawings, which avoids the conventional process of creating on-site working drawings and then unit manufacturing drawings, thereby shortening the construction period compared to conventional processes.Furthermore, when the situation on site changes, the conventional process of repeatedly revising the working drawings and unit manufacturing drawings can be avoided, and by modifying the parameter file, it is possible to respond to changes in the situation on site.

[0062] In this way, the unit processing system 1 of the present invention reduces the effort required for drawing units, moves away from the dependency on individual workers for drawing units, proposes the best units for each site, improves customer satisfaction, and promotes the automation of unit drawing as a future construction model.

[0063] Furthermore, in the unit processing system 1 of the present invention, the selection condition input unit 20 inputs the type of unit, the unit pattern, and the model of equipment used in the unit as selection conditions, and the template model output unit 21 determines the template model to output from multiple types of units based on the input unit type, unit pattern, and unit model.

[0064] This allows the unit processing system 1 of the present invention to be able to handle a wide variety of units by accumulating template models as needed.

[0065] In the above embodiment, an example has been described in which the user terminal 2 is equipped with the unit selection software 25, the parameter editing software 26, and the computer-aided design (CAD) software 27, but the present invention is not limited to this example.

[0066] In another example, the user terminal 2 may be configured without being equipped with the parameter editing software 26, but may be communicatively connected to another terminal equipped with the parameter editing software 26, and may transmit the template model or the parameter editing file to the other terminal. In this case, the template model output unit 21 of the user terminal 2 may transmit the parameter file to the terminal equipped with the parameter editing software, and may use the API to issue an instruction to start the parameter editing software and execute the parameter file.

[0067] In another example, the user terminal 2 may be configured without the CAD software 27 installed, but may be communicatively connected to another terminal installed with the CAD software 27, and may transmit the template model or parameter editing file and the three-dimensional model file to the other terminal. In this case, the template model output unit 21 of the user terminal 2 may transmit the three-dimensional model file to the terminal installed with the CAD software, and may use the API to issue instructions to start the CAD software and execute the three-dimensional model file.

[0068] The terminal on which the parameter editing software 26 is installed and the terminal on which the CAD software 27 is installed may be the same terminal, or may be different terminals.

[0069] Furthermore, the above description of the embodiments of the present invention describes preferred embodiments of the unit processing system according to the present invention, and therefore may include various technically preferable limitations, but the technical scope of the present invention is not limited to these aspects unless there is a specific description that limits the present invention.
