  Hereinafter, details of each embodiment will be described with reference to the accompanying drawings. It should be noted that, in the description of the embodiments and the description of the drawings, components having substantially the same functional configuration will be denoted by the same reference numerals, and redundant description will be omitted.

<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 apparatus according to the present embodiment is used in the design system 10 or the like as illustrated.

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

  As illustrated, the design system 10 is connected to a network NW such as the Internet. Then, it is connected to the external devices M1, M2, M3, etc. via the network NW. When data or operation is input from the external devices M1, M2, M3, etc. connected in this way, the design system 10 receives the data or operation via the network NW. That is, the design system 10 transmits / receives data to / from the external devices M1, M2, M3 and the like via the network NW.

<Example of hardware configuration of design device>
As illustrated, the PC 11 has a hardware configuration including a CPU (Central Processing Unit, hereinafter referred to as “CPU 11H1”), a storage device 11H2, an interface 11H3, and a communication device 11H4, for example, as illustrated.

  The CPU 11H1 is an example of a computing 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. The storage device 11H2 may include an auxiliary storage device such as a hard disk or an SSD (Solid State Drive). Then, the storage device 11H2 stores a program, data, or the like.

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

  Then, the interface 11H3 connects peripheral devices such as the goggles 12 and the pointer device 13. The goggles 12 and the pointer device 13 are examples of devices for using the virtual space. That is, the goggles 12 and the pointer device 13 display the virtual space and then accept an operation on the displayed virtual space.

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

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

  The pointer device 13 is an example of an input device that inputs an operation for pointing an object displayed in the virtual space or 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 be used to 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, attribute information data D08, etc. are input. Other data 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”, “hygiene”, and “electricity” as shown in the figure. Is. For example, the “design” data in the design data D01 is data indicating a design drawing or the like regarding the design of the building.

  The library data D04 is data indicating, for example, the “shape” and “attribute” of a building or a part used for building a building.

  The price list data D05 is data indicating prices of parts and the like procured in 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 input corresponding to the name of the part, such as “part 1”, “part 2”, and “part 3”. Note that the price may be the same part or a plurality of prices may be input, as in the case of “part 2” illustrated. For example, even if the parts are the same, the prices may be different if the suppliers are different or the purchasing conditions such as bulk purchase are different. Therefore, in the price list data D05, a plurality of prices may be input for one component, such as “component 2” illustrated.

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

  The attribute information data D08 is, for example, data indicating various settings regarding the BIM model and related information (hereinafter referred to as “attribute information”). Specifically, as shown in the figure, the attribute information data D08 includes “property (various settings)”, “ID (Identification)”, “source file name”, “project information”, “block name”, and “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" is input.

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

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

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

  FIG. 4 is a diagram showing an example of cost data. As shown in the figure, the cost data D09 indicates, for example, data used for cost calculation and the like. Specifically, first, if there is the price list data D05 and the like, the price of each component can be grasped. With the BIM model, the quantity of each component used in the building can be grasped. Next, by calculating "price x quantity", the cost of each component, which is a breakdown of "material cost", can be grasped.

  When the design data D01 or the like is input, the design drawing or the like is 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 have a plurality of data depending on the degree of detail or the intended use, such as “design drawing level” to “construction drawing level”.

  Then, for example, the technical study data D14, the construction plan data D15, the construction management data D16, and the like may be generated based on the BIM model and the like. Hereinafter, an example in which the data as illustrated is generated will be described.

  With the cost data D09, for example, the estimation process PS01, the cost management process PS02, the budget management process PS03, etc. can be executed. When such a process can be executed, the design system 10 can create a document such as the design document FL1, the bill FL2, or the estimate FL3. That is, by the estimation process PS01, it is possible to calculate the amount of money and the like described in the bill FL2, the quotation FL3 and the like.

  In addition, since the price management process PS02 can calculate the amount of money used for cost management such as variable cost and fixed cost, the amount of money described in documents such as the design document FL1 can be calculated.

  With the budget management process PS03, the amount of money used for managing the budget can be calculated. For example, an expected cost used for preparing a budget or a progress degree used for management based on a construction progress standard is calculated. In this way, the budget management process PS03 can calculate the amount of money and the like described in the quotation FL3.

  With the technical study data D14, for example, processing such as heat / air flow simulation PS04 and static pressure calculation / lift calculation PS05 can be executed. Further, if the technical examination data D14 is present, the processing of the placement simulation PS06 of the pedestal / steel material / hanging / anchor can be executed. Further, with the technical study data D14, a sound simulation PS07 such as noise, silencing, and sound insulation can be executed. In addition, if there is the technical study data D14, processing such as distribution calculation of air volume and water volume and leakage amount calculation PS08 of wind and water can be executed.

  That is, if the technical study data D14 is present, the design system 10 can execute various kinds of processing such as simulation or scientific and technological calculation. Therefore, the design system 10 can execute a simulation or the like and output the simulation result or the like.

  With the construction plan data D15, various plans such as a process plan PS09, a safety plan PS10, an artificial plan PS11, a construction method plan PS12, a carry-in plan PS13, and a trial operation plan PS14 are created. You can

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

  FIG. 6 is a diagram showing an example of construction plan data. As shown in the figure, the construction plan data D15 is, for example, data indicating a schedule or the like in a format such as a so-called Gantt chart. That is, the construction plan data D15 is data indicating a schedule of work or the like performed to construct a building. Therefore, if there is data such as the construction plan data D15, the process of the process plan planning PS09 for formulating a process plan can be executed based on the schedule of each process indicated by the construction plan data D15.

  Similarly, a safety plan in each process, a plan for people in each process, a plan for a construction method, a plan for bringing in equipment and the like, a plan for trial operation, etc. are included in the safety plan PS10, the artificial plan PS11, and the construction method plan. Planning can be performed by processing such as the planning PS12, the carry-in planning PS13, and the trial operation planning PS14.

  The construction management data D16 is data used for various management in construction of a building. For example, at a construction site, progress, actual items, costs, etc. are managed. Of these, for example, the construction management data D16 is used to manage the progress and the actual product. Specifically, if there is the construction management data D16, processing such as the progress management PS15, the order / delivery management PS16, and the inspection / record management PS17 can be executed. For example, a management table, a record, or the like is created by processing such as the progress management PS15, the order / delivery management PS16, and the inspection / record management PS17.

  The change data D17 includes materials and equipment installed in a building (equipment, equipment or parts thereof that are a part of the building) on a VR (Virtual Reality) displayed based on the CAD data D13 and the like. Hereinafter, the data will be generated when an operation of changing “materials and equipment” is performed.

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

  Furthermore, when the intention of the user UR is different from the layout of the materials and equipment, the user UR performs an operation of changing the layout 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 in the virtual space displayed by the goggles 12 to specify the equipment to be changed and perform the operation of changing the arrangement. In this way, the change operation acceptance process PS18 is performed.

  In this way, when the operation for changing the arrangement of the equipment is input by the change operation receiving process PS18, the operation content, that is, the change indicating the equipment for which the arrangement is changed, the position of the changed equipment, etc. Data D17 is generated. Then, the CAD data D13 and the like are changed based on the change data D17.

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

  Hereinafter, as described above, it is assumed that the user UR checks the inside of the building with the goggles 12 after the BIM model and the like are constructed. Note that such work may be performed at any timing. During this work, the installation support will be provided by instructing the installation position of the equipment (including the instruction to set and change the position in advance).

<Functional configuration example>
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 a CAD data input unit FN1, an attribute information data input unit FN2, a virtual space display unit FN3, an operation reception unit FN4, and a restriction unit FN5.

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

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

  The virtual space display means FN3 shows the building in the 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 the 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 and the like.

  The operation receiving unit FN4 performs an operation receiving procedure for receiving an operation for changing the arrangement of the equipment in the virtual space displayed by the virtual space display unit FN3. For example, the operation reception unit FN4 is realized by the pointer device 13 or the like.

  The restriction unit FN5 performs a restriction procedure for restricting the change by the operation reception unit FN4. For example, the restriction unit FN5 is realized by the CPU 11H1 and the like.

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

<Example of data input> (step S01)
In step S01, the design system 10 inputs data. Specifically, data such as CAD data D13 and attribute information data D08 is input to the design system 10.

<Example of setting constraint conditions> (step S02)
In step S02, the design system 10 sets constraint conditions. That is, what kind of constraint is to be performed in the subsequent constraint processing is set.

<VR display example> (step S03)
In step S03, the design system 10 performs VR display. Specifically, the VR and the equipment and the like arranged in the building are displayed on the basis of a program or the like which is installed in advance and performs the VR display.

<Example of determination as to whether or not there is a change operation> (step S04)
In 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, when there is no change operation, the design system 10 ends the entire process.

<Example of Constraint Based on Constraint Condition> (Step S05)
In step S05, the design system 10 restricts the change operation received in the subsequent stage, based on the restriction condition set in step S02. The details of the constraint will be described later.

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

<Example of Correction of CAD Data etc. by Change Data> (Step S07)
In step S07, the design system 10 corrects the CAD data D13 and the like based on the change data D17 generated in step S06.

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

<Example of change operation>
First, when data such as the CAD data D13 and the attribute information data D08 is input in step S01, 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 receives a change operation. The design system 10 can display, for example, a virtual space display screen PN as illustrated by the CAD data D13 and the attribute information data D08.

  Hereinafter, the depth direction in the virtual space (in the figure, the depth direction) is referred to as “Y-axis direction”. Further, the horizontal direction (right and left direction in the figure) orthogonal to the Y-axis direction is referred to as “X-axis direction”. Further, a vertical direction (vertical direction in the figure) perpendicular to the Y-axis direction is referred to as “Z-axis direction”.

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

  Further, the pointer display PT on the virtual space display screen PN is a display linked to the operation by the pointer device 13. Therefore, in the following description, the operation by the pointer device 13 is indicated by the pointer display PT, and an example of the changing operation will be described.

  For example, when the equipment is arranged at the position indicated by the pointer display PT, it is set as the change target TG as illustrated. In this way, when the change target TG is determined, for example, the selection screen SEL as illustrated is displayed.

  The selection screen SEL displays a list or the like for selecting the type of change. For example, the type of change is displayed on the selection screen SEL, and an operation of selecting one type of change is performed by the pointer display PT. 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 size and the like of the change target TG. 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 of changing the route through which the pipe passes if the change target TG is a pipe or the like. If the TG to be changed is not a pipe or the like and is not a material / equipment that changes the route, the option “2. move route” may be restricted by graying out so that it cannot be selected. For example, the route is changed by designating the changed route with the pointer display PT.

  When the change type “3. size change” is selected, the size of the change target TG can be changed. The selectable size may be set in advance.

  When the type of change “4. Move member” is selected, the design system 10 accepts an operation of moving the material / equipment that has become the change target TG. For example, the change target TG is constrained so that it cannot be moved downward from the floor by a constraint condition.

  Equipment is often placed above the floor. Therefore, it is often an error as a change operation that the arrangement is such that the user is stuck on the floor. If there is no restriction and the change target TG can be arranged anywhere, it may be necessary to perform a difficult operation such as operating the pointer device with high accuracy. Therefore, based on the specifications and the like, a position that cannot be arranged is set as a constraint condition that restricts a changeable range or the like so that the position cannot be specified as a movement destination. With such a constraint condition, the user UR can perform an operation without considering whether or not the arrangement is possible, or can change it by a simple operation.

  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, the change target TG may be selectable after the option is selected on the selection screen SEL.

  The change type “5. Delete member” deletes the change target TG from the virtual space. That is, the change target TG is changed so as not to be arranged.

  The changing operation is not limited to changing the arrangement. That is, the information other than the arrangement of the equipment may be changed by the change operation. For example, the 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 illustrated options. For example, the type or color of the pipe may be changed on the selection screen SEL. Also, the names of the options do not have to be the names shown in the figure.

<Example of operation to change the installation position of piping>
The equipment to be changed is, 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 the change. On the other hand, FIG. 10B is an example diagram showing the same state as FIG. 10A by CAD data (an example of 2D). Note that FIG. 10 (B) is for explaining other than the pipe to be changed (hereinafter referred to as “changed pipe PIC”) and the reference right pipe PIR and left pipe PIL from FIG. 10 (A). It is the drawing which abbreviates and shows.

  Therefore, in this example, the change operation is performed on the screen shown in FIG. Display related to operations such as the pointer display PT and the selection screen SEL will be omitted (also omitted in the subsequent drawings). Then, when a change operation is performed on the virtual screen, change data is generated. Next, based on the changed data, the CAD data, that is, the drawing shown in FIG.

  Hereinafter, a case will be described as an example in which the changed pipe PIC is changed from the initial arrangement PS1 to the left direction (in the drawing, the left pipe PIL is in the direction) by the change operation.

  FIG. 11: is a figure which shows the example at the time of changing the installation position of piping. That is, it is a diagram in the middle of changing the arrangement of the changed pipe PIC from the state shown in FIG. 10 (in the figure, an example at the intermediate position PS2 is shown). As shown in FIG. 11 (A) and FIG. 11 (B), compared with the state shown in FIG. 10, the change pipe PIC moves to the left, and the difference is that the change pipe PIC is at the midway position PS2.

  FIG. 12: is a figure which shows the example after changing the installation position of piping. That is, FIG. 12 shows an example in which the change operation is completed from the state shown in FIG. 10 through the state shown in FIG. As illustrated, compared with FIG. 10 and the like, the difference is that the changed pipe PIC is at the changed position PS3.

  In this way, if 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 arrangement of the equipment without the operation of inputting detailed numerical values and the like in the CAD.

  The user UR is not necessarily a person who is accustomed to operations such as CAD. Therefore, it may be difficult to input the contents to be changed into the CAD. For example, in CAD, the layout cannot be changed unless a detailed numerical value is accurately input. On the other hand, when a pointer device or the like is used in the virtual space, it is possible to easily change the arrangement of the equipment and the like by a relatively intuitive operation.

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

<Constraint example>
FIG. 13 is a diagram showing a constraint example. Hereinafter, a case will be described as an example in which the change target TG illustrated in FIG. 9 is changed by “2. Route movement”. That is, the change operation as 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 that the movement is possible only on the same plane as the initial arrangement is set in advance.

  That is, when the change target TG is restricted so that it can be changed only on the same horizontal plane, the arrangement of the change target TG is changed in the horizontal direction, and the height (Z axis) can be made constant. Therefore, in the operation as shown in FIG. 12 (A), the height is the same as the initial placement, no matter what position is designated by the pointer device. On the other hand, if the height can be changed, it is necessary to specify the height. If the degree of freedom of change is too high, the operation may be rather difficult.

  The user UR is not always a person who is familiar with buildings and the like. For this reason, there are cases where the user is not familiar with the positions or rules that cannot be arranged according to various rules. Therefore, due to restrictions, it is possible to prevent instructing a change that cannot be arranged in a range in which the arrangement is impossible even during the operation even if the equipment is not arranged.

  Note that the content of the constraint can be set in advance and may be content other than limiting the movable range such as a horizontal plane. For example, in the operation of “3. size change”, selectable sizes are restricted. In other words, due to the influence of rules or purchasing, 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 where the arrangement is impossible. Specifically, the area where the arrangement is impossible may be displayed by hatching or a predetermined color. In this way, by visually notifying the area where the arrangement is impossible, the user UR can know the position where the arrangement is impossible.

  The constraint method may be, for example, considering the viewpoint and end point of the pipe. Details will be described later in <Modification Example of Plural Pipes to be Connected>.

<Example of changing multiple connected pipes>
FIG. 14: is a figure which shows the 1st example which changes the some piping connected. Hereinafter, an example in which the first pipe PI1 shown in FIG. 14 (A) is designated as a target of change will be described.

  The second pipe PI2 is connected to one end of the first pipe PI1 (the upper end of the first pipe PI1 in the illustrated example). Similarly, it is assumed that the third pipe PI3 is further connected to the other end (the lower end of the first pipe PI1 in the illustrated example) of the first pipe PI1. Information for connecting the first pipe PI1, the second pipe PI2, and the third pipe PI3 is preliminarily input to CAD data or the like.

  Then, an example of an operation of 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 of the case where the first pipe PI1 is selected as a target for change in response to the operation of “2. Route movement”.

  As shown in FIG. 14 (B), 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. Then, it is assumed that an operation of changing the arrangement of the first pipe PI1 to the position shown in FIG. 14B is performed.

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

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

  As described above, when the arrangement of any one of the connected pipes is changed, the length of the connected pipe that has not been changed is also changed. In this way, the state in which the pipes are connected can be maintained even after the change. That is, when changing the arrangement of any of the connected pipes, the operation of changing the length of the connected pipes can be omitted so as to maintain the connected state.

  Note that restrictions may be imposed in the above-described operations. Specifically, the change may be restricted such that the pipe is prevented from moving in the longitudinal direction, or the pipe is moved between the start point and the end point in consideration of the start point and the end point. ..

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

  Further, 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 depending on the specifications. That is, pipes shorter than the minimum length cannot be installed. Therefore, the first pipe PI1 cannot be arranged unless both the second pipe PI2 and the third pipe PI3 have a minimum length or more. Therefore, ensure the minimum length of each pipe at the start and end points. In this way, it is desirable that the arrangement of the first pipe PI1 be changed within a range in which the length of each pipe can be secured. Therefore, the operation is limited to the range in which the minimum length of each pipe can be secured.

  FIG. 15: is a figure which shows the 2nd example which changes the some piping connected. Hereinafter, description will be made by taking the same pipe as that in FIG. 14A as an example. That is, the change target, the connection state, and the like are the same initial states as in FIG. 14, and the duplicate description will be omitted.

  Then, an example of an operation for maintaining the connected state of each pipe and changing the size (thickness) of the first pipe PI1 will be described. It should be noted that the size is not limited to the thickness, and may be other dimensions. Specifically, this is an example of the case where the first pipe PI1 is selected as a target of change by the operation of “3. size change”.

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

  When the operation of changing from FIG. 15 (A) to FIG. 15 (B) is performed, for example, the second pipe PI2 and the third pipe PI3 are linked to 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.

  In many cases, the pipes to be connected cannot be maintained unless the sizes of the pipes match. Therefore, when the size of any of the connected pipes is changed, the design system 10 also changes the size of the connected pipe that is not the target of the change. With this configuration, the state in which the plurality of pipes are connected can be maintained even after the change. That is, when changing the size of any of the connected pipes, the operation of changing the size of each pipe to be connected can be omitted so as to maintain the connected state.

  The number of connected pipes to be changed may not be three. That is, 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 the design system in the second embodiment. The second embodiment is different from the first embodiment in that it has a functional configuration including a display unit FN21 and a carry-in route setting unit FN22. Hereinafter, the same configurations as those in the first embodiment will be denoted by the same reference numerals, and redundant description will be omitted.

  The second embodiment is a configuration that considers the delivery route of materials and equipment.

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

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

<Overall processing example>
FIG. 17 is a flowchart showing an example of overall processing in the second embodiment. Compared with the overall processing in the first embodiment, the difference is that step S21 and step S22 are performed. Hereinafter, the points different from the first embodiment will be mainly described, and the same processes as those in the first embodiment will be denoted by the same reference numerals and redundant description will be omitted.

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

<Example of restrictions based on import route> (step S22)
In step S22, the design system 10 imposes restrictions based on the carry-in route. For example, equipment and materials should not be placed in the area that will be the import route. Details of the constraint will be described later.

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

  Further, the carry-in route may be set as a constraint condition. That is, steps S02 and S21 may be integrated, or may be performed separately as illustrated.

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

  It is assumed that the carry-in equipment EQ is carried into the building through the carry-in entrance R1. Then, it is assumed that the carried-in equipment / equipment EQ carried in from the carry-in entrance R1 is carried toward the equipment / equipment installation position R2 and is arranged in the equipment / equipment installation position R2.

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

  To calculate the carry-in route, for example, first, the setting as shown in FIG. 18B is performed. Specifically, in the setting example shown in FIG. 18B, the start point PTS and the 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 carry-in port R1. On the other hand, the end point PTE is an example of a point indicating the equipment installation position R2. In this way, when the start point PTS and the end point PTE are set, the design system 10 can grasp the positions of the carry-in entrance R1 and the equipment installation position R2.

  Then, the design system 10 calculates the carry-in route RC, for example, as shown in FIG. 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, as shown in FIG. 18C, for example.

  The width or height of the carry-in equipment EQ may be taken into consideration in the carry-in route RC. For example, the width or height of the imported equipment EQ is input in advance in CAD data, attribute information data, or the like. Therefore, the design system 10 can grasp the width or height of the import equipment EQ by referring to the CAD data or the attribute information data. Then, the carry-in route RC is configured by a route capable of ensuring the width or height of the carry-in equipment EQ. That is, the carry-in route RC is composed of only routes that allow the carry-in equipment EQ to pass through.

  The illustrated example is an example in which the width WD is taken into consideration. For example, as shown in the figure, the width WD is set so as to include a width that allows the carry-in equipment EQ to pass through the line serving as the carry-in route RC.

  If the carry-in route RC includes a portion having a narrow width such that the carry-in equipment EQ cannot pass through, the carry-in equipment EQ may be caught at that location and cannot be carried in. Therefore, it is desirable that the carry-in route RC is configured by a route having a width that can be carried in in consideration of the width or height of the carry-in equipment EQ. When such a carry-in route RC is calculated, the carry-in of the carry-in equipment EQ can be smoothly carried out.

  In addition, the carry-in route RC may take into consideration a pillar in a building or an installed material and the like. That is, 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 of the carry-in equipment EQ can be smoothly carried out.

  Further, the carry-in route RC may have a manual route correction, a width change, or the like.

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

<First example of restrictions based on import 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, the range shown in the figure is set as a restricted range based on the carry-in route RC. Hereinafter, the range subject to the constraint will be referred to as “constraint range LE”.

  As shown in the figure, the restricted range LE is displayed, for example, by hatching or the like on the drawing or the like. It should be noted that the method of displaying the restricted range LE may be another method.

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

  Specifically, for example, as shown in the figure, it is assumed that an operation is performed to change the changed material / equipment EQC so as to be arranged within the restricted range LE. In such a case, the changed equipment EQC warns that it cannot be placed on the carry-in route.

  The restriction method is not limited to the warning such as displaying the message ME. For example, the restriction may be that the operation is not accepted even if a change is made to place the changed equipment EQC on the carry-in route. In this case, the changed equipment EQC is processed such as returned to the position before the change. In addition, as a restriction method, for example, the changed equipment EQC arranged on the carry-in route may be emphasized in a blinking manner. Alternatively, the change of the changed equipment EQC may be restricted as follows, for example.

<Second example of restrictions based on import route>
FIG. 20 is a diagram showing a second example of constraints based on the carry-in route in the second embodiment. First, for example, it is assumed that the same constraint range LE as in FIG. 19 is set based on the carry-in route RC.

  Then, for example, it is assumed that the arrangement of the changed material / equipment EQC is changed such that the arrangement shown in FIG. As shown in the figure, all or part of the two modified equipment EQCs are within the restricted range LE. The design system 10 rearranges the layout thus changed, for example, as shown in FIG.

  FIG. 20B is a diagram showing an example after rearrangement. As illustrated, the changed material / equipment EQC is arranged outside the restricted range LE. In this way, the design system 10 rearranges the materials and equipment arranged within the restricted range LE to outside the restricted range LE. By doing so, it is possible to prevent the equipment from being arranged in the restricted range LE.

  Also, the constraint may be enforced as follows.

<Third example of restrictions based on import routes>
FIG. 21 is a diagram showing a third example of restrictions based on the carry-in route in the second embodiment. Hereinafter, a case where the constraint range LE is set as illustrated by the calculation method illustrated in FIG. 18 will be described as an example.

  The restriction may be performed by referring to attribute information data or the like, for example. For example, even if the arrangement is as shown in the figure, if the material / equipment EQS is “removable”, the material / equipment EQS may not be subject to a restriction such as warning or rearrangement.

  For example, the information indicating whether or not "detachable" is possible is input in advance in the attribute information data or the like. Therefore, the design system 10 can determine, by referring to the attribute information data and the like, whether the equipment EQS is “detachable” or the like.

  If the material / equipment EQS is “removable”, the material / equipment EQS can be removed at the time of carry-in even if the material / material EQS is arranged on the carry-in route. In this way, the design system 10 may determine whether or not to make a constraint based on the attribute information data and the like.

  Specifically, the “removable” equipment is a duct or the like. Ducts and the like often have a structure that can be removed and attached relatively inexpensively. Thus, for example, the possibility of “removable” is determined in consideration of the cost of removal and the like. Whether or not the item is “removable” may be determined by factors other than cost.

  Further, the order of loading and the like may be input to the attribute information data. Specifically, for example, "delivery date" is input to the attribute information data. Alternatively, data indicating the carry-in plan may be referred to by the design system 10.

  In other words, if the “delivery date” and the like can be grasped, it is possible to know in what order a plurality of materials and equipment will be carried in. In other words, since the respective materials / equipment are loaded in the order of the “delivery date” earlier, when there are a plurality of materials / equipment, the design system 10 determines the order of loading the materials / equipment based on the “delivery date”. Can be specified.

  Then, the design system 10 may perform the restriction in consideration of the order in which the materials and equipment are loaded. For example, in the illustrated example, when the material / equipment arranged at the material / material installation position R2 is carried in before the material / material EQS, the design system 10 indicates that the material / equipment EQS is within the restricted range LE as illustrated. It may be arranged within the range or may not be restricted.

  Even if the materials and equipment to be carried in later are arranged on the carry-in route, they are not carried in yet at the time of carrying-in, so the carrying-in is often not hindered. Therefore, the design system 10 refers to the order in which the materials and equipment are loaded, and does not restrict the materials and equipment loaded after the materials and materials loaded on the loading route, even if they are placed within the restricted range LE. Good. In this way, if the order of loading and the like are taken into consideration in the determination as to whether or not there is a constraint, the loading plan and the like can be made more flexibly.

  It should be noted that the order in which the materials and equipment are brought in is not limited to the judgment based on the “delivery date”. That is, the order in which the materials and equipment are loaded may be the order in which the materials and materials are loaded or the order before and after the loading. Therefore, as the attribute information data or the like, a number indicating the order of loading or data indicating before and after loading may be input.

  As described above, when the carry-in route is taken into consideration, it is possible to easily carry in the material and the like.

<Third Embodiment>
FIG. 22 is a functional block diagram showing a functional configuration example of the design system in the third embodiment. Compared to the second embodiment, the third embodiment is different in that a rule setting means FN31 and a rule determination means FN32 are added. Hereinafter, the elements described in the first embodiment and the second embodiment will be denoted by the same reference numerals, and duplicated description will be omitted.

  In the third embodiment, the operation receiving unit FN4 is a change operation receiving unit that performs a change operation receiving procedure for receiving a change operation for changing the arrangement or items of the materials and equipment.

  The rule setting means FN31 performs a rule setting procedure for setting a plurality of rules relating to the arrangement or items of materials and equipment. For example, the rule setting means FN31 is realized by an input device or the like.

  The rule determination means FN32 performs a rule determination procedure for determining whether or not the arrangement or item of the equipment and materials violates the rule. For example, the rule determination means FN32 is realized by the CPU 11H1 and the like.

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

  Although not shown in the drawings and the 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 flowchart showing an example of overall processing in the third embodiment. Compared to the first embodiment, the third embodiment is different in that step S31 and step S32 are performed. Hereinafter, the different points will be mainly described and the duplicated description will be omitted.

<Example of setting a plurality of rules> (step S31)
In step S31, the design system 10 sets a plurality of rules. For example, as shown in the figure, the rule can be set by inputting data (hereinafter, referred to as “rule data DR”) indicating a rule regarding arrangement or items of equipment and the like.

  As shown in the figure, a plurality of rules are set. In the illustrated example, “rule 001”, “rule 002”, “rule 003”, “rule 004”, and “rule 005” that are input to the rule data DR are different rules.

  As shown in the figure, the rules are, for example, standards, dimensions, or intervals determined to be protected by laws and regulations such as the Fire Service Act (Law No. 186 of 1948), specifications, or rules established in-house. Etc. Therefore, with the rule data DR, the design system 10 can determine whether or not a predetermined specification, regulation, law, or the like is satisfied. The details of the determination will be described later.

<Rule check example> (step S32)
In step S32, the design system 10 checks the rule set in step S31. By such a check, it is determined whether or not the arrangement or items of the equipment and materials violate the rules. The check timing, the check result output format, and the like may be different depending on the contents of the check. Further, by checking the rules, for example, the following restrictions may be imposed.

<First example of constraints based on rules>
FIG. 24 is a diagram showing a first example of restrictions on changes in the third embodiment. Specifically, in the scene as shown in FIG. 9, in order to change the type of the duct as shown in the case where the duct is selected as the target of the change and “3. resize” is selected. 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 for changing various specifications of the duct. Specifically, a so-called pull-down menu or the like is provided on the setting screen PSET for each parameter.

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

  Hereinafter, a pull-down menu PL1 which is an example of a GUI for selecting “size” will be described as an example. In this example, the items are “300”, “350”, “400”, etc. displayed by the pull-down menu PL1. As described above, the item is, for example, a value indicating the size of the equipment and the like. The item is an option that is displayed to change a value or the like preset in the attribute information data to another value or the like and is a candidate for the change.

  Furthermore, the pull-down menu PL1 is an example of a selection display that displays a plurality of items. Note that the selection display is not limited to the pull-down menu format, and may be a GUI or the like that displays a plurality of items and that accepts an operation of selecting a plurality of items to be displayed.

  The pull-down menu PL1 is an example of a GUI that accepts a change operation for changing an item. That is, in the following example, when the user UR wants to change an item, the user UR performs the changing operation by selecting any one of the items displayed in the pull-down menu PL1. When the value or the like indicated by the item selected by the change operation is confirmed, the attribute information data can be changed by overwriting the attribute information data.

  In this example, first, it is assumed that the unit pressure loss is 1.0 Pa / m or less when the duct is installed by the rule. Based on the rule, a size smaller than “300” is a case where the rule is violated.

Therefore, for example, when “1,100 m ³ / h” is input on the setting screen PSET, the item “size” is checked. That is, the design system 10 determines whether or not each item of “size” is a rule violation under the condition of “1,100 m ³ / h”. Then, in this example, as a result of the determination, a size smaller than “300” is determined to be an item of rule violation.

  In such a case, pull-down menu PL1 is displayed so that an operation of selecting a size less than "300" cannot be performed. That is, even if the size of less than "300" can be purchased by reflecting the determination result, it is not displayed on the menu as illustrated. In this way, the design system 10 hides the items that violate the rules, for example. It should be noted that the design system 10 may be restricted by a method other than the non-display so as not to accept the change operation for changing the item into the rule violation.

  In this way, when the rule determination result is reflected on the GUI or the like, it is possible to prevent the user UR from making a change that is a rule violation.

  When there are a plurality of rules, for example, the strictest rule result may be applied. Besides, the type of GUI is not limited to the type shown in the figure, and a numerical value may be input or a button format may be used. The constraint method may differ depending on the type of GUI, the input format, and the like. Specifically, in the GUI such as menus and buttons, since the input format is to select an item, the constraint method is to hide the item or not to select the item. On the other hand, in a GUI such as a text box, when a numerical value as an item is input, for example, the numerical value is checked, and if it is a numerical value that violates the rule, an error is displayed.

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

<Second example of rule-based constraint>
FIG. 25 is a diagram showing a second example of restrictions on changes in the third embodiment. Similar to FIG. 24, the illustrated example is an example in which a size less than “300” is a rule violation, based on the rule of installing ducts.

  In the illustrated example, the method of reflecting the determination result is different. Hereinafter, different points will be mainly described.

  This example is an example of a constraint for notifying a size that is a rule violation by color coding, as shown in the figure. As shown in the figure, “200” and “250” that are sizes less than “300” are displayed in a different color from the sizes that are “300” and larger. In this way, if the sizes that violate the rules are distinguished by color coding or the like, the user UR can recognize the items that violate the rules.

  When a plurality of rules are set, the determination result may be different. For example, in a certain rule, the size “200” is a determination result (hereinafter, referred to as “first determination result”) that is a rule violation. On the other hand, in other rules, it is assumed that the size of “250” is the determination result (hereinafter referred to as “second determination result”) that is a rule violation. In this way, when the determination result differs for each rule, each determination result may be displayed in a different color as shown in the figure.

  The illustrated example is an example in which the first determination result is displayed in the first color C1. On the other hand, the illustrated example is an example in which the second determination result is displayed in the second color C2. As in this example, if the first color C1 and the second color C2 are color-coded for each determination result, it can be known whether the violation is determined based on different rules.

  Note that the constraint method is not limited to color-coding the items that violate the rule, as shown in the figure. For example, the constraint method may be an error when an item that violates the rule is selected, an item that violates the rule is emphasized, hatched, or grayed out. That is, as long as it is possible to distinguish between items that are determined to be rule violations and items that are not, it is possible to use any form of restriction method.

<Third example of rule-based constraint>
FIG. 26 is a diagram showing a third example of restrictions on changes in the third embodiment. As shown, the piping or the like may be determined and restricted based on rules. First, as shown in the figure, it is assumed that two pipes, a first installation pipe PI31 and a second installation pipe PI32, are arranged. Then, it is assumed that the distance between the pipes is set to be a certain distance or more based on a rule.

  First, it is assumed that the arrangement is as shown in FIG. That is, before the change, as shown in the figure, the interval between the first installation pipe PI31 and the second installation pipe PI32 (hereinafter referred to as the “pre-change interval DS1”) does not violate the rule, that is, there is a sufficient interval. It is assumed that the arrangement is set.

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

  Specifically, the post-change interval DS2 is narrower than the pre-change interval DS1 and narrower than the interval determined by the rule.

  The design system 10 detects, for example, an arrangement such as the post-change interval DS2 by the determination. Then, a message ME or the like notifying that there is an arrangement that violates the rule is displayed. In this way, the design system 10 carries out a constraint of issuing a warning for a change that results in a rule violation arrangement. In this way, when the change operation that causes the rule violation is received, the user UR can recognize the rule violation when the message ME or the like notifies that the rule violation has occurred.

  Note that the determination result may be displayed by, for example, highlighted CH or the like, as shown in the figure. The example shown is an example of notifying that the highlighted CH is a rule violation. The highlighted CH may be blinking or the like. Even with such a method, the user UR can recognize the rule violation.

  Further, the arrangement of the materials and equipment to be judged is not limited to the interval between the pipes. For example, the target 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 according to the rules. In this way, it may be determined based on the law or the like whether or not the materials and equipment required to be installed are installed. When such a determination is made, it is possible to prevent forgetting to arrange legal equipment.

  The number of pipes is not limited to two. For example, if the distance between the pipes is the target of the determination, the respective intervals may be determined in three or more pipes.

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

  Therefore, as compared with the third embodiment, the fourth embodiment is different in that the display unit, the operation receiving unit, and the like are prepared for each user.

  Specifically, the display unit FN21A and the display unit FN21B are, for example, the display unit 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.

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

  Further, the operations by the respective users may be performed simultaneously or at different timings.

  Then, when each user performs an operation of changing the arrangement 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 the operation content, the date and time when the operation was performed, the name of the user who performed the operation, the location where the operation was performed, a combination thereof, and the like. Is. That is, the operation history data D40A and the operation history data D40B indicate what kind of operation is performed, when the operation is 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 / absence of a rule violation, the identification information that identifies the operation that was the check target, the date and time when the check was performed, the identification information that identifies the applied rule, When the rule is violated, it is data that records the violated item or a combination thereof. That is, the operation history data D40A and the operation history data D40B are data indicating information that can trace the operation or the user who has violated the rule when the rule violated the performed operation.

  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 format shown, the operation history data D40A and the check result data D41A are data recorded for the operation performed by the first user UR1. On the other hand, the operation history data D40B and the check result data D41B are data recorded for the operation performed by the second user UR2. In this way, when the data is recorded separately for each user, the history or the check result can be associated with the user. The data may be collected in one database or the like, for example. That is, it is sufficient that the history and the check result can be associated with the user. For example, if the user identification number is attached and each data corresponds to the user, the format and format of the data can be any format. Good.

  In this way, when the history or the check result is recorded in association with the user, the tracking can be performed later. Specifically, when a change is made, if the change is a rule violation, it may be necessary to make a further change so as not to be a rule violation. In such a case, it will be easier to make further changes if the user who made the changes can be tracked.
