Details of each embodiment will be described below with reference to the accompanying drawings. In addition, in the descriptions of the specifications and drawings according to each embodiment, constituent elements having substantially the same functional configuration are denoted by the same reference numerals, thereby omitting redundant explanations.

<First Embodiment>
<Overall configuration example>
FIG. 1 is a conceptual diagram showing an example of the overall configuration of a design system and an example of the hardware configuration of a design device. For example, the design device according to the present embodiment is used in a design system 10 or the like as illustrated.

Specifically, the design system 10 includes a PC (Personal Computer, hereinafter referred to as “PC 11”), which is an example of a design device, goggles 12, and a pointer device 13, for example.

As illustrated, the design system 10 connects with a network NW such as the Internet. Then, it connects with the external devices M1, M2, M3, etc. via the network NW. When data, operations, etc. are input from external devices M1, M2, M3, etc. connected in this manner, the design system 10 receives data, operations, etc. via the network NW. That is, the design system 10 transmits and receives data to and from the external devices M1, M2, M3, etc. via the network NW.

<Hardware Configuration Example of Design Device>
The PC 11 has a hardware configuration including, for example, a CPU (Central Processing Unit, hereinafter referred to as "CPU 11H1"), a storage device 11H2, an interface 11H3, and a communication device 11H4, as shown.

The CPU 11H1 is an example of an arithmetic device and a control device. That is, the CPU 11H1 realizes processing or control in cooperation with the storage device 11H2 based on the program.

The storage device 11H2 is a main storage device such as a memory. Note that the storage device 11H2 may have an auxiliary storage device such as a hard disk or an SSD (Solid State Drive). The storage device 11H2 stores programs, data, and the like.

The interface 11H3 connects peripheral devices such as the goggles 12 and the pointer device 13, for example, by wire or wirelessly, and transmits and receives data to and from the peripheral devices. Specifically, the interface 11H3 is, for example, a connector and a processing IC (Integrated Circuit). Note that the interface 11H3 may be connected to a peripheral device via a network.

The interface 11H3 connects peripheral devices such as the goggles 12 and the pointer device 13 . Also, the goggles 12 and the pointer device 13 are examples of devices for using the virtual space. In other words, the goggles 12 and the pointer device 13 display the virtual space and then receive an operation for the displayed virtual space.

The communication device 11H4 communicates with an external device or the like via a network NW or the like.

The goggles 12 are an example of an output device that displays virtual space. For example, the goggles 12 are an HMD (Head Mounted Display) or the like.

The pointer device 13 is an example of an input device for inputting operations such as pointing an object displayed in the virtual space and selecting a menu.

<Data configuration example>
FIG. 2 is a block diagram showing a configuration example of data realized by the design system. For example, the design system 10 can handle data as illustrated.

First, various data are input to the design system 10 by an external device, an input device, or the like. Specifically, for example, design data D01, construction data D02, operation data D03, library data D04, price list data D05, specification data D06, equipment data D07, and attribute information data D08 are input. Data other than this may be input to the design system 10 .

The design data D01, the construction data D02, and the operation data D03 are data created for each purpose, such as "design", "structure", "air conditioning", "sanitation", and "electricity", as shown in the figure. is. For example, the "design" data in the design data D01 is data indicating blueprints and the like relating to the design of a building.

The library data D04 is, for example, data indicating the "shape" and "attributes" of a building or parts used to construct the building.

The price list data D05 is data indicating prices of parts and the like procured for construction. For example, the price list data D05 is the following data.

FIG. 3 is a diagram showing an example of price list data. For example, as shown in the figure, each price is entered corresponding to the name of the part, such as "Part 1", "Part 2", and "Part 3". It should be noted that the price may be entered for a plurality of parts, such as "part 2" shown in the figure, even for the same part. For example, even if the parts are the same, the prices may differ if the supplier is different or if the purchase conditions such as bulk purchases are different. Therefore, in the price list data D05, a plurality of prices may be entered for one part, such as "part 2" shown in the drawing.

The specification data D06 and the facility data D07 are data indicating the specifications of the facilities and parts installed in the building.

The attribute information data D08 is, for example, data indicating various settings and related information (hereinafter referred to as "attribute information") regarding the BIM model. Specifically, as illustrated, the attribute information data D08 contains "property (various settings)", "ID (Identification)", "source file name", "project information", "block name", "plan Title", "Dimensions", "Installation date", "Installation conditions such as temperature", "Area information (area type and area name, etc.)", "Material information such as inclusions", "Type parameters" and "Work data” etc. is input.

For example, information such as specifications related to buildings, equipment, parts, etc. is stored in the form of document data D10, skeleton data D11, table data D12, and the like.

For example, a BIM model is composed of at least CAD data D13, attribute information data D08, and the like. However, other data such as the document data D10, the skeleton data D11, or the table data D12 may be referred to when using the BIM model.

Then, as shown in the figure, if there is the price list data D05 and the like, for example, the following cost data D09 can be generated.

FIG. 4 is a diagram showing an example of cost data. As illustrated, the cost data D09 indicates data used for cost accounting, for example. Specifically, first, if there is price list data D05, etc., the price of each part can be grasped. And if there is a BIM model, the quantity of each part used in the building can be grasped. Next, by calculating "price x quantity", the cost of each part, which is the breakdown of "material cost", can be grasped.

Further, when the design data D01 and the like are input, the design drawings and the like are stored as, for example, the following CAD data D13.

FIG. 5 is a diagram showing an example of CAD data. As illustrated, the CAD data D13 is 3D data or the like. Note that the CAD data D13 may include 2D data. Further, the CAD data D13 may include a plurality of data according to the degree of detail or usage, such as "design drawing level" to "working drawing level".

Then, for example, technical examination data D14, construction plan data D15, construction management data D16, etc. may be generated based on the BIM model or the like. An example in which data as illustrated is generated will be described below.

With the cost data D09, for example, the estimation process PS01, the cost control process PS02, the budget control process PS03, etc. can be executed. If such processing can be executed, the design system 10 can create, for example, a design document FL1, an invoice FL2, or an estimate FL3. That is, by the estimation process PS01, the amounts and the like described in the bill FL2 and the estimate FL3 can be calculated.

In addition, since the cost management process PS02 can calculate the amounts used for cost management such as variable costs and fixed costs, etc., it is possible to calculate the amounts described in documents such as the design document FL1.

The budget management process PS03 can calculate the amount of money used to manage the budget. For example, an expected cost used to create a budget or a degree of progress used for percentage-of-completion management is calculated. In this way, the budget management process PS03 can calculate the amount and the like described in the quotation FL3.

With the technical study data D14, for example, processes such as heat/airflow simulation PS04 and static pressure calculation/head calculation PS05 can be executed. Also, if the technical study data D14 is available, it is possible to execute processing such as a placement simulation PS06 for pedestals, steel materials, hangers, anchors, and the like. Furthermore, with the technical study data D14, it is possible to execute sound simulations PS07 such as noise, silence, and sound insulation. In addition, if there is the technical study data D14, it is possible to execute processes such as distribution calculation of air volume and water volume and calculation PS08 of leakage amount such as wind and water.

That is, with the technical study data D14, the design system 10 can execute processing such as various simulations or scientific calculations. Therefore, the design system 10 can execute a simulation or the like and output a simulation result or the like.

With construction plan data D15, various plans such as process plan formulation PS09, safety plan formulation PS10, artificial plan formulation PS11, construction method plan formulation PS12, carry-in plan formulation PS13, trial operation plan formulation PS14, etc. can be created. can be done.

For example, the construction plan data D15 is the following data.

FIG. 6 is a diagram showing an example of construction plan data. As illustrated, the construction plan data D15 is, for example, data indicating schedules in the form of a so-called Gantt chart. That is, the construction plan data D15 is data indicating the schedule of the work to be performed for constructing the building. Therefore, if there is data such as the construction plan data D15, it is possible to execute the processing of the process planning PS09 for formulating a process plan based on the schedule of each process indicated by the construction plan data D15.

Similarly, plans for safety in each process, plans for people in each process, plans for construction methods, plans for bringing in facilities, etc., and plans for test runs are included in safety planning PS10, human planning PS11, and construction method planning. Planning PS12, carrying-in planning PS13, trial operation planning PS14, etc. can be used for planning.

The construction management data D16 is data used for various management in building construction. For example, at construction sites, progress, actual products, costs, and the like are managed. Of these, for example, the construction management data D16 is used to manage progress and actual products. Specifically, if there is construction management data D16, processes such as progress management PS15, order/delivery management PS16, and inspection/record management PS17 can be executed. For example, the progress management PS15, order/delivery management PS16, inspection/record management PS17, etc. create management tables or records.

The change data D17 includes materials and equipment to be installed in the building (equipment, equipment, parts thereof, etc. that are part of the building) on VR (Virtual Reality) displayed based on the CAD data D13 and the like. hereinafter simply referred to as "materials and equipment") is data generated when an operation to change is performed.

Specifically, a building is designed, and design details and the like are input to the CAD data D13 and the like. The layout of materials and equipment in the building is also input to the CAD data D13. With such CAD data D13, it is possible to virtually display, for example, the state of a completed building on the goggles 12 or the like through VR display or the like. Therefore, the user UR or the like can see the state of the completed building and the arrangement of materials and equipment in the building even at the design stage in the virtual space. In this way, by using VR display to show an estimate of the completion of a building, for example, it is possible to prevent discrepancies between the building client and the designer.

Furthermore, if the user's intention and the arrangement of materials and equipment are different, the user UR performs an operation to change the arrangement of the materials and equipment by looking at the VR display displayed in the VR display processing PS19. For example, in the overall configuration shown in FIG. 1, the user UR uses the pointer device 13 to specify materials and equipment to be changed in the virtual space displayed by the goggles 12, and performs an operation to change the arrangement. In this manner, the change operation acceptance process PS18 is performed.

In this way, when an operation for changing the placement of materials and equipment is input by the change operation reception processing PS18, the content of the operation, that is, the change indicating the position of the materials and equipment after the change and the materials and equipment whose placement is to be changed is displayed. Data D17 is generated. Then, the CAD data D13 and the like are changed based on the change data D17.

In addition, "table output" or the like may be performed to display each piece of information in a table format or the like. Further, "2D drawing output" or the like may be performed by converting the CAD data D13 or the like to display a design drawing or the like in a 2D drawing. In addition, "sharing of information with the site", etc., in which each piece of information is transmitted and received to and from a mobile terminal, etc., may be performed. Furthermore, "input/output of production information" or the like for transmitting and receiving each information used for construction of a building may be performed.

Hereinafter, as described above, it is assumed that the user UR needs to confirm the inside of the building with the goggles 12 after the BIM model or the like is constructed. Such work may be performed at any timing. In this work, it is assumed that the installation is supported by instructing the installation position of the materials and equipment (the position is set in advance and includes an instruction to change it).

<Example of functional configuration>
FIG. 7 is a functional block diagram showing a functional configuration example of the design system. For example, the design system 10 has a functional configuration including CAD data input means FN1, attribute information data input means FN2, virtual space display means FN3, operation reception means FN4, and restriction means FN5.

The CAD data input means FN1 performs a CAD data input procedure for inputting CAD data D13 indicating equipment and materials. For example, the CAD data input means FN1 is realized by the communication device 11H4 or the like.

The attribute information data input means FN2 performs an attribute information data input procedure for inputting attribute information data D08 indicating attribute information, etc., about materials and equipment. For example, the attribute information data input means FN2 is implemented by the communication device 11H4 or the like.

The virtual space display means FN3 displays the building in virtual space based on the attribute information data D08, the CAD data D13, and the like. Then, the virtual space display means FN3 performs a virtual space display procedure for arranging and displaying materials and equipment in the virtual space based on the attribute information data D08, the CAD data D13, and the like. For example, the virtual space display means FN3 is realized by the goggles 12 or the like.

The operation reception means FN4 performs an operation reception procedure for receiving an operation to change the layout of materials and equipment in the virtual space displayed by the virtual space display means FN3. For example, the operation reception unit FN4 is realized by the pointer device 13 or the like.

The constraint means FN5 performs a constraint procedure to constrain the change by the operation reception means FN4. For example, the restricting means FN5 is implemented by the CPU 11H1 or the like.

<Overall processing example>
FIG. 8 is a flowchart showing an example of overall processing.

<Data Input Example> (Step S01)
In step S01, the design system 10 inputs data. Specifically, data such as the CAD data D13 and the attribute information data D08 are input to the design system 10. FIG.

<Example of Setting Constraints> (Step S02)
In step S02, the design system 10 sets constraints. In other words, it sets what type of constraint is to be applied in the process of applying the constraint in the subsequent stage.

<VR Display Example> (Step S03)
In step S03, the design system 10 performs VR display. Specifically, based on a pre-installed VR display program or the like, the building and materials and equipment placed in the building are displayed in VR.

<Example of determining whether or not there is a change operation> (step S04)
At step S04, the design system 10 determines whether or not there is a change operation. Next, when there is a change operation, the design system 10 proceeds to step S05. On the other hand, if there is no change operation, the design system 10 terminates the overall processing.

<Constraint Example Based on Constraint Conditions> (Step S05)
In step S05, the design system 10 restricts the change operation received later based on the constraint conditions set in step S02. Details of the restrictions will be described later.

<Example of acceptance of change operation> (step S06)
In step S06, the design system 10 accepts the change operation after being restricted by step S05. Then, based on the received change operation, the design system 10 generates change data D17.

<Correction example of CAD data etc. by change data> (step S07)
At step S07, the design system 10 corrects the CAD data D13 and the like based on the change data D17 generated at step S06.

As shown in the figure, when the CAD data D13 and the like are corrected in step S07, the design system 10 proceeds to step S03 and performs VR display based on the corrected CAD data.

<Example of change operation>
First, in step S01, when data such as the CAD data D13 and the attribute information data D08 are input, the design system 10 can build a BIM model. Then, if there is a BIM model, for example, the design system 10 can perform the following VR display in step S03.

FIG. 9 is a diagram showing a display example of a virtual space that accepts a change operation. The design system 10 can display, for example, a virtual space display screen PN as shown, using the CAD data D13, the attribute information data D08, and the like.

Hereinafter, the depth direction in the virtual space (the depth direction in the drawings) will be referred to as the "Y-axis direction." Also, the horizontal direction perpendicular to the Y-axis direction (in the drawing, the left-right direction) is referred to as the "X-axis direction." Further, the vertical direction (vertical direction in the drawing) that is perpendicular to the Y-axis direction is referred to as the "Z-axis direction."

In the illustrated example, the virtual space display screen PN displays the interior of the building in VR. Specifically, as shown in the figure, the virtual space display screen PN arranges and displays materials and equipment such as piping PI. That is, the piping PI displayed on the virtual space display screen PN is arranged and displayed at the position input by the CAD data D13.

Also, the pointer display PT on the virtual space display screen PN is a display linked to the operation of the pointer device 13 . Therefore, in the following description, operations by the pointer device 13 are indicated by the pointer display PT, and examples of change operations will be described.

For example, when materials and equipment are placed at the position indicated by the pointer display PT, as shown in the figure, it is set as the change target TG. When the TG to be changed is determined in this way, for example, a selection screen SEL as shown is displayed.

The selection screen SEL displays a list or the like for selecting the type of change. For example, types of change are displayed on the selection screen SEL, and an operation of selecting one type of change is performed by the pointer display PT. Note that the type of change may be set in advance.

For example, when the change type "1. Measurement" is selected, the design system 10 displays the dimensions of the change target TG. Note that the dimension value is a value input to the CAD data D13, the attribute information data D08, or the like.

Further, when the type of change "2. route movement" is selected, the design system 10 accepts an operation to change the route along which the pipe passes when the TG to be changed is a pipe or the like. If the TG to be changed is not a pipe or the like and is not a material or equipment that changes the route, the option "2. Move route" may be grayed out or the like so that it cannot be selected. For example, the route is changed by designating the changed route with a pointer display PT.

When the change type "3. Size change" is selected, the size of the change target TG can be changed. Note that the selectable sizes may be set in advance.

When the type of change "4. Move member" is selected, the design system 10 accepts an operation to move the material and equipment that is the target TG for change. For example, the change target TG is constrained by constraint conditions so that it cannot move below the floor.

Equipment is often placed above the floor. Therefore, it is often the case that an arrangement that sinks into the floor is an error as a change operation. If there are no restrictions and the TG to be changed can be placed anywhere, difficult operations such as operating a pointer device with high precision may be required. Therefore, a position that cannot be arranged based on the specifications or the like is set as a constraint condition that restricts a changeable range or the like so that the position cannot be designated as a movement destination. With such a constraint, the user UR can operate without considering whether or not the arrangement is possible, or can change the arrangement with a simple operation.

Note that the selection screen SEL may be displayed before the change target TG is selected. For example, the selection screen SEL may be displayed from the beginning. Then, after an option is selected on the selection screen SEL, the TG to be changed may be selected.

The change type "5. Delete member" deletes the change target TG from the virtual space. In other words, the change target TG is changed so as not to be arranged.

Note that the change operation is not limited to changing the arrangement. That is, information other than the arrangement of materials and equipment may be changed by a change operation. For example, attribute information may be changed by a change operation. That is, the types that can be changed on the selection screen SEL are not limited to the options shown. For example, the type or color of piping may be changed on the selection screen SEL. Also, the name of the option may not be the name shown in the figure.

<Example of operation to change the installation position of piping>
Materials and equipment to be changed are, for example, piping. Hereinafter, the operation for changing the installation position of the pipe in the virtual space will be described separately before, during, and after the change.

FIG. 10 is a diagram showing an example before changing the installation position of the pipe. Specifically, FIG. 10A is a diagram showing the virtual space before change. On the other hand, FIG. 10(B) is a diagram of an example showing the same state as FIG. 10(A) by CAD data (an example of 2D). Note that FIG. 10(B) shows, from FIG. 10(A), piping to be changed (hereinafter referred to as "changed piping PIC"), and other than the reference right piping PIR and left piping PIL. It is drawing which abbreviate|omits and shows.

Therefore, in this example, the change operation is performed on the screen shown in FIG. 10(A). Note that the pointer display PT, selection screen SEL, and other displays related to operations are omitted (also omitted in subsequent drawings). Then, when a change operation is performed on the virtual screen, change data is generated. Next, based on the change data, the CAD data, that is, the drawing shown in FIG. 10B is changed accordingly.

Hereinafter, an example will be described in which the change operation changes the arrangement of the change pipe PIC from the initial position PS1 to the left direction (the direction in which the left pipe PIL is present in the drawing).

FIG. 11 is a diagram showing an example of changing the installation position of the pipe. That is, it is a diagram in the middle of changing the arrangement of the change pipe PIC from the state shown in FIG. 10 (the figure shows an example in the middle position PS2). As shown in FIGS. 11(A) and 11(B), compared with the state shown in FIG. 10, the change pipe PIC is moved leftward, and the change pipe PIC is at the intermediate position PS2.

FIG. 12 is a diagram showing an example after changing the installation position of the pipe. That is, FIG. 12 is an example of a case where the change operation is completed from the state shown in FIG. 10 through the state shown in FIG. 11 . As illustrated, compared with FIG. 10 and the like, the difference is that the changed pipe PIC is at the post-change position PS3.

In this way, when the position of the pipe or the like is changed on the virtual screen, the change is reflected in the CAD data or the like. Therefore, the user UR can change the layout of materials and equipment without inputting detailed numerical values into the CAD.

The user UR is not necessarily a person who is familiar with operating CAD or the like. Therefore, it may be difficult to input the contents to be changed to the CAD. For example, in CAD, the layout cannot be changed unless detailed numerical values are entered accurately. On the other hand, if a pointer device or the like is used in the virtual space, it is possible to easily change the arrangement of materials and equipment with relatively intuitive operations.

Then, restrictions are imposed on operations as shown in FIGS. 10 to 12 . For example, the change pipe PIC can be moved by changing such that the arrangement cannot be changed except on the same horizontal plane (in the illustrated example, it is on the XY plane and the value of the Z axis is constant). Limited range. Concretely, the restriction is performed as follows, for example.

<Constraint example>
FIG. 13 is a diagram illustrating an example of constraints. An example of changing the TG to be changed shown in FIG. 9 by "2. route movement" will be described below. That is, the change operation shown in FIGS. 10 to 12 is performed on the pipe to be changed TG. For such a change operation, for example, a constraint condition is set in advance that the object can only be moved on the same plane as the initial layout.

That is, if the change is restricted to be possible only on the same horizontal plane, the change target TG can be horizontally changed in arrangement and the height (Z-axis) can be kept constant. Therefore, in the operation shown in FIG. 12(A), the height is the same as the initial placement regardless of the position specified by the pointer device. On the other hand, if the height can be changed, an operation to specify the height is required. If the degree of freedom of change is too high in this way, the operation may rather become difficult.

Also, the user UR is not limited to a person who is knowledgeable about buildings and the like. Therefore, in addition to various rules, there may be cases where the user is not familiar with the positions where placement is impossible or the rules. Therefore, it is possible to prevent the operator from instructing a change that cannot be placed by making it impossible to place materials and equipment in a range where placement is impossible due to restrictions.

Note that the content of the restriction can be set in advance, and may be content other than restricting the range of movement, such as a horizontal plane. For example, in the operation "3. Resize", the sizes that can be selected are restricted. That is, due to the influence of rules, purchases, or the like, sizes that cannot be arranged may be restricted so that they cannot be selected.

In addition, the restriction method may be, for example, emphasizing and displaying a range in which arrangement is impossible. Specifically, the range in which arrangement is impossible may be indicated by hatching, a predetermined color, or the like. In this way, by visually notifying the range where placement is impossible, the user UR can know the positions where placement is impossible.

Constraint methods may also consider, for example, viewpoints and endpoints of piping. Details will be described later in <Modified example of a plurality of connected pipes>.

<Example of changing multiple connected pipes>
FIG. 14 is a diagram showing a first example of changing a plurality of connected pipes. An example in which the first pipe PI1 shown in FIG. 14A is designated as a change target will be described below.

A second pipe PI2 is connected to one end (the upper end of the first pipe PI1 in the illustrated example) of the first pipe PI1. Similarly, the first pipe PI1 is further connected to a third pipe PI3 at the other end (the lower end of the first pipe PI1 in the illustrated example). It is assumed that information for connecting the first pipe PI1, the second pipe PI2 and the third pipe PI3 is input in advance to CAD data or the like.

An example of an operation for maintaining the connected state of each pipe and changing the arrangement of the first pipe PI1 on the X-axis will be described. Specifically, this is an example in which the first pipe PI1 is selected as a change target for the operation of "2. route movement".

As shown in FIG. 14B, when the first pipe PI1 is selected as a change target, it can be changed so as to move in the X-axis direction, for example. Assume that an operation is performed to change the arrangement of the first pipe PI1 to the position shown in FIG. 14(B).

In the state shown in FIG. 14(A), when the operation shown in FIG. 14(B) is performed, for example, the second pipe PI2 and the third pipe PI3 are interlocked with the change of the first pipe PI1. is changed as shown in FIG. 14(C).

Specifically, the length of the second pipe PI2 is changed so that the connection with the changed first pipe PI1 can be maintained. On the other hand, the third pipe PI3 is changed so as to shorten the length of the pipe so that the connection with the changed first pipe PI1 can be maintained. The length and the like of the pipes connected in this manner are changed so that the connection can be maintained in the same manner as before the change.

As described above, when the arrangement of any of the pipes among the connected pipes is changed, the length of the connected pipes that are not subject to change is also changed. In this way, the connected state of the pipes can be maintained even after the change. That is, when changing the arrangement of one of the connected pipes, it is possible to omit the operation of changing the length of the connected pipes so as to maintain the connected state.

In addition, restrictions may be performed in the above operations. Specifically, the modification may be constrained such as prohibiting the pipe from moving in the longitudinal direction, or considering the start and end points, moving the pipe between the start and end points, etc. .

In the illustrated example, the longitudinal direction is the Y-axis direction. It is assumed that the first pipe PI1 is arranged parallel to the Y-axis direction. That is, due to restrictions, the direction in which the pipe can be moved is limited to, for example, the X-axis direction. Therefore, an operation to move the first pipe PI1 in the Y-axis direction is subject to restrictions such as being unacceptable.

Also, the starting point is the left end portion of the second pipe PI2 in the illustrated example. On the other hand, the end point is the right end portion of the third pipe PI3 in the illustrated example. The minimum length of piping is required according to specifications and other factors. That is, piping shorter than the minimum length cannot be installed. Therefore, it is impossible to arrange the first pipe PI1 unless both the second pipe PI2 and the third pipe PI3 have a minimum length or longer. Therefore, the minimum length of each pipe is ensured at the start point and the end point. In this way, it is desirable to change the arrangement of the first pipes PI1 within a range in which the length of each pipe can be secured. Therefore, the operation is restricted to the extent that the minimum length of each pipe can be secured.

FIG. 15 is a diagram showing a second example of changing a plurality of connected pipes. In the following, the same piping as in FIG. 14A will be described as an example. That is, the object to be changed, the connection state, etc. are assumed to be in the same initial state as in FIG. 14, and overlapping descriptions will be omitted.

An example of an operation for changing the size (thickness) of the first pipe PI1 while maintaining the connected state of each pipe will be described. Note that the size is not limited to the thickness, and other dimensions may be used. Specifically, this is an example in which the first pipe PI1 is selected as a change target by the operation "3. Size change".

As shown in FIG. 15(B), when the first pipe PI1 is selected as a change target, for example, the size of the first pipe PI1 can be changed. Then, as shown in FIGS. 15(A) to 15(B), it is assumed that an operation is performed to increase the size of the first pipe PI1.

15(A) to FIG. 15(B), for example, the second pipe PI2 and the third pipe PI3 are interlocked with the operation on the first pipe PI1, 15(C).

Specifically, the second pipe PI2 and the third pipe PI3 are changed so that the size of each pipe becomes thicker so that the connection with the changed first pipe PI1 can be maintained.

If the pipes to be connected do not match in size, the connection cannot be maintained in many cases. Therefore, when the size of any one of the connected pipes is changed, the design system 10 also changes the size of the connected pipes that are not subject to change. In this way, even after the change, the state in which the plurality of pipes are connected can be maintained. That is, when changing the size of one of the connected pipes, it is possible to omit the operation of changing the size of each connected pipe so as to maintain the connected state.

Note that the number of connected pipes to be changed need not be three. In other words, the pipes to be changed may be two connected pipes or four or more connected pipes.

<Second embodiment>
FIG. 16 is a functional block diagram showing a functional configuration example of a design system according to the second embodiment. The second embodiment differs from the first embodiment in that it has a functional configuration including display means FN21 and carry-in route setting means FN22. Hereinafter, configurations similar to those of the first embodiment are denoted by the same reference numerals, and overlapping descriptions are omitted.

2nd Embodiment is the structure which considers the carrying-in route of materials and equipment.

The display means FN21 displays a route through which materials and equipment are carried into a building, a route through which materials and equipment are carried out, or a route used for maintenance (hereinafter referred to as "carry-in route"). For example, the display means FN21 is implemented by an output device or the like.

The carry-in route setting means FN22 sets the carry-in route. For example, the carry-in route setting means FN22 calculates the carry-in route and sets the calculated carry-in route. A method of calculating the carry-in route will be described later. For example, the carry-in route setting means FN22 is implemented by the CPU 11H1 or the like.

<Overall processing example>
FIG. 17 is a flow chart showing an example of overall processing in the second embodiment. Compared to the overall process in the first embodiment, it differs in that steps S21 and S22 are performed. Hereinafter, the points different from the first embodiment will be mainly described, and the same processing as in the first embodiment will be denoted by the same reference numerals, and redundant description will be omitted.

<Example of setting the delivery route for materials and equipment> (Step S21)
In step S21, the design system 10 sets the carry-in route of materials and equipment. For example, the carry-in route is set in maintenance information or the like. Also, the carry-in route is input in advance by the carry-in trader or the like in the maintenance information or the like, for example. Alternatively, the carry-in route is calculated from, for example, the relationship between the carry-in entrance and the installation position. A method of calculating the carry-in route will be described later.

<Constraint example based on carry-in route> (Step S22)
In step S22, the design system 10 restricts based on the carry-in route. For example, it is prohibited to place materials and equipment in the range that will be the carry-in route. Details of the constraints will be described later.

In the illustrated processing example, the VR display is performed in step S03, but the carry-in route may not be displayed on the virtual screen. That is, the delivery route may be displayed, for example, on a 2D CAD display.

Also, the carry-in route may be set as a constraint. In other words, steps S02 and S21 may be performed integrally, or may be performed separately as shown.

<Calculation example of carry-in route>
FIG. 18 is a diagram showing an example of calculation of the carry-in route in the second embodiment. In the following description, the state shown in FIG. 18(A) is taken as an example. First, in this example, the material/equipment EQ shown in FIG. 18(A) is carried.

It is assumed that the material/equipment to be carried in EQ is carried into the building from the carry-in entrance R1. Then, it is assumed that the material/equipment EQ carried in from the entrance R1 is transported toward the material/equipment installation position R2 and placed at the material/equipment installation position R2.

For example, the carry-in route is the shortest route from the carry-in entrance R1 to the materials/equipment installation position R2. That is, the design system 10 can identify the carry-in route by calculating the shortest route from the carry-in entrance R1 to the material/equipment installation position R2.

For the calculation of the carry-in route, for example, settings as shown in FIG. 18B are first performed. Specifically, in the setting example shown in FIG. 18B, a start point PTS and an end point PTE are set in order to calculate the carry-in route.

The starting point PTS is an example of a point indicating the entrance R1. On the other hand, the end point PTE is an example of a point indicating the material/equipment installation position R2. Thus, when the start point PTS and the end point PTE are set, the design system 10 can grasp the positions of the loading entrance R1 and the material/equipment installation position R2.

Then, the design system 10 calculates the carry-in route RC, for example, as shown in FIG. 18(C). Specifically, the design system 10 calculates the shortest route connecting the start point PTS and the end point PTE as the carry-in route RC, for example, as shown in FIG. 18(C).

The width or height of the material/equipment to be carried in EQ may be taken into consideration for the carry-in route RC. For example, the width or height of the material/equipment to be brought in EQ is input in advance into CAD data, attribute information data, or the like. Therefore, the design system 10 can grasp the width, height, etc. of the materials/equipment to be brought in EQ by referring to the CAD data or the attribute information data. The carry-in route RC is configured by a route that can secure the width or height of the carry-in materials/equipment EQ. In other words, the carry-in route RC is composed only of routes through which the carry-in materials and equipment EQ can pass.

The illustrated example is an example when the width WD is considered. For example, as shown in the figure, the width WD is set so as to include a width that allows the material/equipment to be carried in EQ to pass through the line serving as the carry-in route RC.

If the carrying-in route RC includes a narrow portion where the carrying-in materials/equipment EQ cannot pass through, the carrying-in materials/equipment EQ may be caught at that portion and the carrying-in may not be possible. Therefore, it is desirable that the carry-in route RC is configured with a route wide enough for carry-in, considering the width or height of the carry-in materials/equipment EQ. When such a carry-in route RC is calculated, the carry-in materials and equipment EQ can be carried in smoothly.

It should be noted that the carry-in route RC may take into consideration the pillars in the building or the materials and equipment that have already been installed. In other words, the carry-in route RC is configured by a route that avoids pillars or installed materials and equipment. When such a carry-in route RC is calculated, the carry-in materials and equipment EQ can be carried in smoothly.

Also, the carry-in route RC may be manually corrected or changed in width.

When the carry-in route RC is calculated as described above (step S21), the design system 10 restricts the operation as follows (step S22) when performing the change operation (step S06), for example.

<First example of restrictions based on delivery route>
FIG. 19 is a diagram showing a first example of restrictions based on the carry-in route in the second embodiment. For example, a case where the carry-in route RC shown in FIG. 18 is calculated will be described as an example.

In this example, based on the carry-in route RC, the range as shown is set as a restricted range. Hereinafter, the range to be restricted is referred to as "restricted range LE".

As shown in the drawing, the restricted range LE is displayed, for example, by hatching or the like on the drawing or the like. Note that the restricted range LE may be displayed by other methods.

When an attempt is made to place materials and equipment within the restricted range LE, for example, a message ME indicating a warning or the like is displayed as shown in the figure.

Specifically, for example, as shown in the figure, it is assumed that an operation is performed to change the changed materials/equipment EQC so as to be placed within the restricted range LE. In such cases, the modified equipment EQC will warn that it cannot be placed on the delivery route.

Note that the restriction method is not limited to a warning such as displaying the message ME. For example, the restriction may be such that even if a change is made to place the changed materials/equipment EQC on the carry-in route, no operation is accepted. In this case, the changed equipment EQC is processed such as returning to the position before the change. In addition, the restriction method may be, for example, to emphasize the changed material/equipment EQC arranged on the carry-in route by blinking. Alternatively, changes to the modified equipment EQC may be constrained, for example, as follows.

<Second example of restrictions based on delivery route>
FIG. 20 is a diagram showing a second example of restrictions based on the carry-in route in the second embodiment. First, it is assumed that, for example, a restricted range LE similar to that in FIG. 19 is set based on the carry-in route RC.

Then, for example, it is assumed that the arrangement of the changed materials and equipment EQC is changed so as to be arranged as shown in FIG. 20(A). As shown, the two modified equipment EQCs are both wholly or partially within the constraint range LE. The design system 10 rearranges the arrangement changed in this way, for example, as shown in FIG. 20(B).

FIG. 20B is a diagram showing an example after rearrangement. As shown, the modified equipment EQC is placed outside the constraint range LE. In this way, the design system 10 rearranges the materials and equipment placed within the restricted range LE outside the restricted range LE. In this way, equipment can be prevented from being placed in the restricted range LE.

Constraints may also be implemented as follows.

<Third example of restrictions based on delivery route>
FIG. 21 is a diagram showing a third example of restrictions based on the carry-in route in the second embodiment. A case in which the restricted range LE is set as illustrated by the calculation method or the like illustrated in FIG. 18 will be described below as an example.

Constraints may be made with reference to attribute information data or the like, for example. For example, even with the arrangement shown, if the equipment EQS is "removable," the equipment EQS may not be subject to warnings, relocations, or other restrictions.

For example, information as to whether or not it is “removable” is entered in attribute information data or the like in advance. Therefore, the design system 10 can determine whether or not the material/equipment EQS is "removable" by referring to the attribute information data and the like.

If the materials and equipment EQS is "removable", even if it is placed on the carry-in route, the materials and equipment EQS can be removed at the time of carry-in to secure the carry-in route. In this manner, the design system 10 may determine whether or not to impose restrictions based on attribute information data and the like.

Specifically, "removable" materials and equipment are ducts and the like. Ducts and the like are often structures that can be removed and installed relatively inexpensively. In this way, for example, the cost of removal and the like are taken into account to determine whether or not the device is “removable”. It should be noted that whether or not "removable" may be determined by factors other than cost.

In addition, the order of carrying-in and the like may be input to the attribute information data. Specifically, for example, "delivery date" is input to the attribute information data. Alternatively, the design system 10 may refer to data indicating the carry-in plan.

That is, if the "delivery date" and the like can be grasped, the order in which the multiple materials and equipment will be brought in can be known. In other words, the materials and equipment are brought in in order of the earliest "delivery date", so if there are multiple materials and equipment, the design system 10 determines the order in which the materials and equipment are brought in based on the "delivery date". can be identified.

Then, the design system 10 may restrict the order in which materials and equipment are brought in. For example, in the illustrated example, when the materials/equipment placed at the materials/equipment installation position R2 are brought in before the materials/equipment EQS, the design system 10 determines that the materials/equipment EQS is within the restricted range LE as illustrated. It may be placed within the range or not constrained.

Materials and equipment that will be carried in later, even if placed on the carry-in route, are not yet carried in at the time of carry-in, so in many cases they do not interfere with carry-in. Therefore, the design system 10 refers to the order in which the materials and equipment are brought in, and assumes that the materials and equipment that are brought in after the materials and equipment that are brought in on the carry-in route are not restricted even if they are arranged within the restricted range LE. good too. In this way, if the order of carrying-in and the like is taken into account in determining whether or not to impose restrictions, it is possible to make a carrying-in plan more flexibly.

The order in which materials and equipment are brought in is not limited to being determined based on the "delivery date". That is, as for the order in which materials and equipment are brought in, it is only necessary to know the order in which the materials and equipment are brought in, or before and after them. Therefore, as the attribute information data, etc., a number indicating the order in which items are brought in or data indicating before and after the items are brought in may be input.

As described above, if the carrying-in route is taken into consideration, the carrying-in of materials and equipment can be facilitated.

<Third Embodiment>
FIG. 22 is a functional block diagram showing a functional configuration example of the design system according to the third embodiment. Compared with the second embodiment, the third embodiment differs in that rule setting means FN31 is added. Elements described in the first and second embodiments are denoted by the same reference numerals, and duplicate descriptions are omitted.

The rule setting means FN31 sets rules to be referred to when the restriction means FN5 imposes restrictions. For example, the rule setting means FN31 is realized by an input device or the like.

Details of the rules and details of the setting method will be described later.

Although not shown in the drawings and description, the third embodiment can be combined with the second embodiment, that is, the configuration including the carry-in route setting means FN22.

<Overall processing example>
FIG. 23 is a flow chart showing an example of overall processing in the third embodiment. Compared with the first embodiment, the third embodiment differs in that steps S31 and S32 are performed. In the following, different points will be mainly described, and redundant descriptions will be omitted.

<Setting Example of Multiple Rules> (Step S31)
At step S31, the design system 10 sets a plurality of rules. For example, a rule can be set by inputting data indicating the contents of the rule (hereinafter referred to as "rule data DR"), etc., as shown in the figure.

As illustrated, it is desirable to set multiple rules. In the illustrated example, "Rule 001", "Rule 002", "Rule 003", "Rule 004" and "Rule 005" input to the rule data DR are different rules.

As shown in the figure, the rules are, for example, the dimensions or intervals stipulated to be observed by laws and regulations such as the Fire Service Act (Act No. 186 of 1948), specifications, or internal rules. be. Details of the rules will be described later.

<Example of rule check> (step S32)
At step S32, the design system 10 checks the rules set at step S31. Note that the timing of checking, the output format of the check results, and the like may differ depending on the content of the rule. Also, by checking the rules, for example, the following constraints may be enforced.

<First example of rule-based constraints>
FIG. 24 is a diagram showing a first example of restrictions on changes in the third embodiment. Specifically, in the scene shown in FIG. 9, when a duct is selected as a change target and "3. Size change" is selected, for example, to change the type of duct as shown in the figure. This is an example in which the GUI (Graphical User Interface) of is displayed.

That is, the GUI is a setting screen PSET or the like that allows various specifications of the duct to be changed. Specifically, the setting screen PSET is configured by providing a so-called pull-down menu or the like for each parameter that can be set.

In the illustrated example of the setting screen PSET, settings can be made to select the shape, etc., such as "round duct". Similarly, in the illustrated example of the setting screen PSET, it is possible to select the type, etc., such as "air supply duct". Also, in the example of the setting screen PSET shown, settings can be made to select the volume of the gas to be sent per unit time, such as "1,100 m ³ /h". Also, in the illustrated example of the setting screen PSET, settings such as "300" can be made to select the size and the like. Note that the types and the like that can be set are not limited to the types shown in the figure, and other types may be available.

A pull-down menu PL1, which is an example of a GUI for selecting "size", will be described below as an example.

In this example, first, it is assumed that the rule stipulates that the unit pressure loss is 1.0 Pa/m or less when installing a duct. Based on that rule, a size of less than "300" is considered to be a violation of the rule.

In such a case, the pull-down menu PL1 is selected so that sizes less than "300" cannot be selected. That is, as a rule check result, a size of less than "300" is determined to be a rule violation. Reflecting the check result, even if sizes less than "300" can be purchased, they are not displayed on the menu as shown.

In this way, when the rule check result is reflected in the GUI or the like, it is possible to prevent the user UR from making changes that violate the rules.

Note that if there are multiple rules, for example, the strictest rule result may be applied. In addition, the type of GUI is not limited to the type shown in the figure, and it may be possible to input numerical values or in the form of buttons.

Further, the constraint method based on the rule check result may be, for example, the following method.

<Second example of constraint based on rules>
FIG. 25 is a diagram showing a second example of restrictions on changes in the third embodiment. The illustrated example is, first, similar to FIG. 24, based on the rule for installing ducts, a size of less than "300" is a violation of the rule.

In the illustrated example, the method of reflecting the check result is different. The different points will be mainly described below.

This example, as illustrated, is an example of a constraint that notifies a size that violates the rules for color coding. As illustrated, sizes "200" and "250" that are less than "300" are displayed in a different color than sizes "300" and above. In this way, if the size that violates the rule is distinguished by color coding or the like, the user UR can grasp the change that violates the rule.

Note that if multiple rules are set, the check results may differ. For example, in a certain rule, it is assumed that a size of "200" is a rule violation check result (hereinafter referred to as "first check result"). On the other hand, in another rule, it is assumed that the size of "250" is a rule violation check result (hereinafter referred to as "second check result"). In this way, when the check results differ for each rule, the check results may be displayed in different colors as shown in the figure.

The illustrated example is an example of displaying the first check result in the first color C1. On the other hand, the illustrated example is an example of displaying the second check result in the second color C2. As in this example, if each check result is color-coded into a first color C1 and a second color C2, it can be seen whether violations have been determined based on different rules.

Note that the constraint method is not limited to color-coding items that violate the rules, as shown in the figure. For example, the constraint method may set an error when a rule-violating item is selected, highlight the rule-violating item, hatch it, or gray it out. In other words, as long as it is possible to distinguish between items determined to be rule violations and items that are not rule violations, any form of constraint method may be used.

<Third example of rule-based constraints>
FIG. 26 is a diagram showing a third example of restrictions on changes in the third embodiment. As shown, piping and the like may be checked and constrained based on rules. First, it is assumed that two pipes, a first installation pipe PI31 and a second installation pipe PI32, are arranged as illustrated. Also, it is assumed that the intervals between the pipes are determined based on the rule so that the distances should be equal to or greater than a certain distance.

First, assume that the state is as shown in FIG. That is, before the change, as shown in the figure, the interval between the first installed pipe PI31 and the second installed pipe PI32 (hereinafter referred to as "pre-change interval DS1") does not violate the rule, that is, the interval is sufficiently large. It is assumed that

Assume that the arrangement of the first installation pipe PI31 is changed as shown in FIG. 26(B). That is, FIG. 26B is a diagram showing the state after the change. Then, in the changed state, the interval between the first installation pipe PI31 and the second installation pipe PI32 (hereinafter referred to as "post-change interval DS2") violates the rule.

Specifically, it is assumed that the post-change interval DS2 is narrower than the pre-change interval DS1 and narrower than the interval defined by the rule.

The design system 10 detects by checking for conditions such as, for example, the post-change interval DS2. Then, a message ME or the like is displayed to notify that there is a part where the rule is violated. In this manner, design system 10 enforces constraints that warn against changes that result in rule-violating placements. In this way, when a rule-violating change is made, the user UR can recognize the rule-violation when notified by a message ME or the like that the rule-violation has occurred.

Note that the check result may be displayed, for example, by highlighting CH or the like, as shown in the figure. The illustrated example is an example of notifying that the portion highlighted CH violates the rule. Note that the highlighting CH may be flashing or the like. This method also allows the user UR to recognize rule violations.

Also, the check item is not limited to the interval between pipes. For example, the object of change may be a wall. Specifically, the wall may be changed to a partition wall. In such cases, there is an obligation to install a damper depending on the rules. In this manner, it may be checked whether or not the materials and equipment that are obligated to be installed under laws and regulations are installed. If such a check is performed, it is possible to prevent forgetting to arrange legal equipment.

Note that the number of pipes is not limited to two. For example, when the interval between pipes is a check item, the intervals may be checked for three or more pipes.

<Fourth Embodiment>
FIG. 27 is a functional block diagram showing a functional configuration example of the design system according to the fourth embodiment. For example, in the fourth embodiment, as illustrated, the design system 10 of the third embodiment or the like is used by a plurality of users.

Therefore, when compared with the third embodiment, the fourth embodiment differs in that the display means, the operation reception means, etc. are prepared for each user.

Specifically, the display means FN21A and the display means FN21B are, for example, the display means FN21 in the third embodiment.

Similarly, the operation receiving means FN4A and the operation receiving means FN4B are, for example, the operation receiving means FN4 in the third embodiment.

A case where there are two users, a first user UR1 and a second user UR2, will be described below as an example. However, the number of users may be plural, and may be three or more.

Moreover, the operations by each user may be performed at the same time or at different timings.

Then, when each user performs an operation to change the layout or the like, the design system 10 generates data such as operation history data D40A, operation history data D40B, check result data D41A and check result data D41B.

The operation history data D40A and the operation history data D40B are data indicating the history of each operation. Specifically, the operation history data D40A and the operation history data D40B are data for recording operation details, date and time when the operation was performed, the name of the user who performed the operation, the location where the operation was performed, or a combination thereof. is. That is, the operation history data D40A and the operation history data D40B indicate what kind of operation was performed, when the operation was performed, and the like. The operation history data D40A and the operation history data D40B may be so-called logs or the like.

The check result data D41A and the check result data D41B are data indicating the check result based on the rule performed for each operation. Specifically, the check result data D41A and the check result data D41B include the presence or absence of rule violation, identification information identifying the operation to be checked, the date and time when the check was performed, identification information identifying the applied rule, This is the data for recording the item or combination of items or the like that violated the rule when the rule is violated. In other words, the operation history data D40A and the operation history data D40B are data indicating information that can track the user or the operation that violates the rule when the operation performed violates the rule.

Further, the operation history data D40A, the operation history data D40B, the check result data D41A and the check result data D41B are associated with the user. For example, in the illustrated format, the operation history data D40A and the check result data D41A are data recorded for operations performed by the first user UR1. On the other hand, the operation history data D40B and the check result data D41B are data recorded with respect to operations performed by the second user UR2. In this way, when data is recorded separately for each user, it is possible to associate history or check results with users. Note that the data may be put together in one database or the like, for example. In other words, it is sufficient if the history, check results, etc. can be associated with the user. good.

In this way, when the history, check results, etc. are recorded in association with the user, they can be tracked later. Specifically, when a change is made, if the change violates the rules, it may be necessary to make further changes so as not to violate the rules. In such cases, being able to track the user who made the change makes it even easier to make the change.
