Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a construction plan support system for supporting a construction plan in civil engineering / architecture, and in particular, it is possible to three-dimensionally display a construction status that changes with the progress of construction according to the construction plan. The present invention relates to a construction planning support system and method.
[0002]
[Prior art]
Conventionally, a construction plan support system disclosed in Patent Document 1 is known. In this system, the process plan program for creating a construction plan and the CAD program for creating a three-dimensional model of each construction member are linked, and the construction status according to the progress of the construction according to the construction plan is tertiary. It can be displayed originally. More specifically, a layer on which a three-dimensional model is drawn is associated with each work type included in the construction plan created by the process plan program, and the designation information of the layer associated with each work type is given to the CAD program. The CAD program can display the construction status in a three-dimensional manner by drawing a specified layer in an overlapping manner. At this time, the layer designation information is switched according to the type of work that changes according to the progress of the construction, so that the change in the construction status can be displayed as an animation. In addition, this system has a built-in walk-through program, and the function can be used to draw the construction situation as seen from an arbitrary position in an arbitrary direction.

[0004]
[Problems to be solved by the invention]
In the above conventional construction support system, when drawing with the walkthrough program, the 3D model data of the construction situation to be drawn is temporarily stored in a storage device such as a hard disk, and then the walkthrough program is started and stored. Drawing processing is performed by reading the 3D model data again. However, the amount of data of the three-dimensional model data representing the construction status is enormous, and it takes a lot of time to store data by the CAD program and to read data by the walk-through program. For this reason, if the user wants to stop the construction status that is displayed as an animation at any point in time and want to walk-through the status, the user must wait for a long time until the display is displayed, and the operability is not good. .
[0005]
The present invention has been made in view of the above points, and while displaying an animation of the construction status that changes according to the progress of the construction, the viewpoint can be freely moved inside the construction status at an arbitrary time, and the line-of-sight direction can be changed. It is an object of the present invention to make it possible to quickly perform a freely changed display, that is, a walk-through display.

Is provided, that is, a walk-through display function.
[0012]
The walk-through program 16 reads the 3D object data for all the work types included in the process table created by the process planning program 12 in a lump and then reads the 3D objects included in the instructed layer. Combine to build a 3D model. As a result, as will be described later, it becomes unnecessary to read the three-dimensional object data when the walk-through program 16 starts animation display or walk-through display, thereby speeding up the processing. The computer system 1 executes the walk-through program 16 to realize the “walk-through means” described in the claims, and the layer managed by the program 16 is the “group” described in the claims. It corresponds to.
[0013]
As will be described in detail below, the interface program 14 associates the layers of the CAD program 10 and the walkthrough program 16 with each work type of the network process table created by the process planning program 12 and Indicates the layer to be displayed. As a result, the walk-through program 16 can display a three-dimensional display of the construction status that changes in accordance with the progress of the construction as described above, and the construction status at an arbitrary point in time can be viewed from any point in the interior. Walk-through display. The computer system 1 executes the interface program 14 to realize “association means” and “instruction means” described in the claims.
[0014]
In the present embodiment, for example, Windows (registered trademark) is used as an operating system for executing each program, and AutoCAD (registered trademark), which is a commercially available CAD program, is used as the CAD program 10 as the process planning program 12. MS-Project (trade name), which is a commercially available process planning program, and NavisWorks (registered trademark), which is a commercially available walkthrough display program, are used as the walkthrough program 16, respectively. However, the commercially available programs that can be used are not limited to these, and other programs having equivalent functions may be used, or each program may be created by itself.
[0015]
The interface program 14 is created by a Windows programming language. According to the programming language for Windows, a window including various menus, buttons, icons, input fields, etc. is defined, and a desired function can be obtained by describing a processing procedure corresponding to a mouse operation to each menu, button, etc. The program which has is realizable.
[0016]
Hereinafter, the construction plan support system of this embodiment will be described in detail. In the following description, it is assumed that the work schedule has been created by the process planning program 12.
[0017]
FIG. 2 shows an example of a display screen of the construction plan support system. As shown in FIG. 2, in the construction planning support system, a display window (hereinafter referred to as a process display window) 20 of a process planning program 12, a display window (hereinafter referred to as an interface display window) 22 of an interface program 14, and a walkthrough. A display window (hereinafter referred to as a construction status display window) 24 of the program 16 is displayed in a multi-window format.
[0018]
In the process display window 20, a network process table created by the process planning program 12 is displayed. That is, as shown in FIG. 2, on the left side in the process display window 20, for each work type included in the work, the start date (display field 20 a), the required period (display field 20 b), and the name of each work type (display field) 20c) is displayed in a table, and the schedule of each work type is displayed on the right side of the screen. In the construction status display window 24, the construction status at the selected construction stage is three-dimensionally displayed.
[0019]
A menu bar 23 including four menu items, that is, “file”, “edit”, “draw”, and “help” is displayed at the top of the interface display window 22.
[0020]
FIG. 3 shows the interface display window 22 when the menu item “file” in the menu bar 23 is clicked. As shown in FIG. 3, when the menu item “file” is clicked, commands for opening, closing, saving, etc. of the project file and CAD file, commands for reading the layer information file, and the like are displayed. The Here, the project file is a file created by the process planning program 12. The project file stores data defining the network process chart (that is, the name, start date, end date, required period, etc. of each type of work included in the process chart). In the CAD file, data defining the three-dimensional object of each member involved in the construction is stored together with data indicating the layer in which each object should be included. Furthermore, the layer information file is a file in which information indicating an association between a work type and a layer described later is stored. The display screen shown in FIG. 2 shows a state where the project file and the CAD file are opened after the interface program 14 is started.
[0021]
FIG. 4 shows the interface display window 22 when the menu item “edit” is clicked on the menu bar 23. As shown in FIG. 4, when the menu item “edit” is clicked, commands “associate work type and layer”, “mass property”, and “update project data to latest state” are displayed.
[0022]
The “associate work type and layer” command is a command for setting an association between each work type included in the process table and a layer to which each object belongs in the CAD program 10 and the walk-through program 16. As described later, the display of the construction status at a certain construction stage is performed by superimposing and displaying the layers associated with the construction type corresponding to the construction stage.
[0023]
FIG. 5 shows the interface display window 22 when the “associate work type and layer” command is selected. As shown in FIG. 5, when the “associate work type and layer” command is selected, a layer association window 25 is displayed in the interface display window 22. The layer association window 25 includes an association list display area 26 for displaying a list of work types and layers associated with each work type, a layer list display area 27 for displaying a list of layers that can be associated with each work type, and “displaying a layer as a display”. An “add” button 28, an “add layer as non-display” button 30, a “save setting” button 32, a “close” button 34, a trash can icon 36, and a display switching icon 38 are included. Note that the layers displayed in the layer list display area 27 are acquired from the layer information included in the CAD file.
[0024]
In the association list display area 26 shown in FIG. 5, “1-road facility processing”, “2-temporary lining cloth excavation”, “3-intermediate pile BH”, “4-underground wall pile joint”, etc. Represents a work type name, and corresponds to each work type included in the process table displayed in the process display window 20. In addition, the items displayed under each work type in the association list display area 26 (“Nakabori Naka” under “2-Temporary lining” and “3- Intermediate pile BH” “Intermediate pile cutting 1”, “intermediate pile cutting 2”,..., “Intermediate pile 1”, “intermediate pile 2”,... Indicate the layer names associated with the respective types of work. “-Display” added after the layer name indicates that the layer is displayed (display on state) when drawing the construction status of each work type, and “-Hide” added after the layer name. "Indicates that the layer is not displayed (display off state) .For example, the layer names" intermediate pile 1 "," intermediate pile 2 ", and" intermediate pile 3 "constitute the member" intermediate pile " These three layers display the entire “intermediate stake”, i.e. In this case, the “intermediate pile” is constructed by a plurality of construction types or construction zones, and each part of the “intermediate pile” constructed in each construction type or construction section is composed of layers “intermediate pile 1”, “intermediate pile 2”, “intermediate pile 3”. In this way, when one member is constructed by a plurality of work types or work sections and this member is drawn in a plurality of layers corresponding to each work type or work section, By using a layer name with a number assigned to the member name, the user can easily select the layers corresponding to the same member collectively.
[0025]
When one of the types of work is selected in the association list display area 26 and any layer is selected in the layer list display area 27, when the "Add layer as display" button 28 is clicked, it is selected. The selected layer is associated with the selected work type as the display-on state. When the “Add layer as non-display” button 30 is clicked, the selected layer is associated with the selected work type as a display-off state. By repeating such an operation, an arbitrary number of layers can be associated with each work type as a display-on state or a display-off state.
[0026]
When any layer name in the work type / layer association list display area 26 is dragged and dropped on the “trash box” icon 36, the association between the layer and the work type is deleted. Further, when any layer name displayed in the work type / layer association list display is dragged and dropped onto the “display switching” icon 38, the display on / off state of the layer is inverted. Each time the association between the work type and the layer is newly set or deleted, or the display on / off state of the layer is inverted, the display of the association list display area 26 is updated.
[0027]
After the layer is associated with each work type as described above, when the “setting save” button 32 is clicked, the set association is saved in the layer information file. When the “close” button 34 is clicked, the layer association window 25 is closed.
[0028]
The “mass property” command shown in FIG. 4 is a command for acquiring the volume of the three-dimensional object for each layer. In this embodiment, the object is defined as a solid model, and the volume of each object is held as incidental information of the object. In the “mass property” command, the volume of the object for each layer is obtained using this information. FIG. 6 shows the interface display window 22 when the “mass property” command is selected. As shown in FIG. 6, when the “mass property” command is selected, a mass property display window 42 is displayed, and the volume of the object for each layer is displayed in this window.
[0029]
FIG. 7 is a diagram showing the entire display screen when “animation and progress diagram display” is selected from the menu item “draw” on the menu bar 23. As shown in FIG. 7, when “animation and progress diagram display” is selected, an “animation and progress diagram display” window 44 is displayed in the interface display window 22. In the “animation and progress diagram display” window 44, a drawing participation layer setting area 46 for setting a layer to participate in drawing, a “select all layers” button 48, a “deselect all” button 50, a “non-selection of A line” button 52, “B line non-selection” button 54, “reset” button 56, “animation execution” button 58, “progress diagram display” button 60, “confirmation state selection” button 62, and “close” button 64. The
[0030]
In the drawing participation layer setting area 46, all layers included in the CAD file are displayed in a list together with their corresponding check boxes. When the check box is checked, the layer is reflected in the drawing of the construction status in the construction status display window 24. The check state of the check box is inverted every time the check box is clicked with the mouse. When the “select all layers” button 48 is clicked, the check boxes for all layers are checked, and when the “deselect all” button 50 is clicked, the check boxes for all layers are unchecked. . In this way, since the display layer can be arbitrarily set, the user can select and observe only a portion of interest from a complicated construction situation.
[0031]
The functions of the “A line non-selection” button 52 and the “B line non-selection” button 54 are as follows. For example, when displaying the construction status including the underground continuous wall, the inside of the underground continuous wall cannot be displayed unless a part of the underground continuous wall is hidden. Therefore, the layer of the members constituting the underground continuous wall is a layer (hereinafter referred to as A line side layer) and a back layer (hereinafter referred to as B line side layer) which draws the near side as viewed from a certain viewpoint. The symbols “−A” and “−B” are added after each layer name. For example, when the inside of the underground continuous wall can be displayed by hiding the A line side layer, the “A line non-selection” button 52 is clicked to hide the A line side layer all at once. Let it be a choice. As described above, the “A line non-selection” button 52 and the “B line non-selection” button 54 are functions for collectively specifying the layers to be hidden so that the inside of the surrounding part can be displayed. have.
[0032]
After the layers participating in the drawing are set as described above, the construction status corresponding to the progress of the process is displayed three-dimensionally by clicking the “execute animation” button 58 or the “display progress diagram” button 60. In addition, the inside of the construction status at an arbitrary time can be displayed in a walk-through manner.
[0033]
FIG. 8 shows a display screen when the “execute animation” button 58 is clicked. As shown in FIG. 8, when the “animation execution” button 58 is clicked, the construction state display screen for displaying the change in the construction state three-dimensionally is displayed by the walk-through program 16. In this construction status display, a display control window 76 including a reverse reproduction button 78, a reverse frame advance button 80, a stop button 82, a forward frame advance button 84, a forward continuous reproduction button 86, and a “close” button 88 is displayed. Is provided. When the forward frame advance button 84 is clicked, the display of the construction status is advanced one frame ahead, and when the reverse frame advance button 80 is clicked, the display of the construction status is returned one frame later. Further, when the forward reproduction button 86 is clicked, a forward animation display of the construction status is started, and when the backward reproduction button 72 is clicked, an animation display of the reverse construction status is started.
[0034]
Note that the above-mentioned “frame” is set for each starting time of each type of work. That is, the interface program 14 sorts the work types in the order of the start date (for the work types having the same start date, the order is further sorted in the order of the end date). For example, when the display is advanced one frame, the sorted work types In accordance with this order, instruction information to the effect that the layer associated with the next work type as the display-on state should be displayed is supplied to the walk-through program 16. Receiving this instruction information, the walkthrough program 16 displays an image in which the three-dimensional objects belonging to the instructed layer are superimposed on the construction status display screen. In this way, the display of the construction status can be advanced or returned one frame at a time. The animation display of the construction status is realized by continuously displaying or returning the display of the construction status in units of frames.
[0035]
FIGS. 9-11 shows an example of a mode that the display of the construction status display window 24 advances by animation display. In the examples shown in FIGS. 9 to 11, the excavated soil 200 is gradually being excavated. As described above, according to the animation display, it is possible to grasp the progress of the construction in a three-dimensional manner, and it is very easy to determine whether the created construction plan has any inconvenience such as member interference. .
[0036]
Moreover, the construction situation displayed on the construction situation display screen by animation can be stopped at an arbitrary point of time, and a walk-through display inside the construction situation can be performed. The walk-through display can be performed by the user operating the operation means 18 such as a keyboard, a mouse, a trackball, and a joystick to change the viewpoint position and the line-of-sight direction in the three-dimensional model. 12 to 15 show screens during the walk-through display. In this example, a state is shown in which the vehicle enters the part A in the construction state shown in FIG. 8 and moves forward. As can be seen from these drawings, the walk-through display makes it possible to check the construction status in detail on the screen as if entering the construction site and moving around freely.
[0037]
As described above, according to the construction plan support system of the present embodiment, it is possible to display the change in the construction status with the passage of time in a three-dimensional manner, and arbitrarily enter the construction status at an arbitrary time point. It is possible to perform a real-time walk-through display that moves and arbitrarily changes the line-of-sight direction. For this reason, after creating a construction plan, the users of this system will be able to follow the construction plan in the same way as if they were actually working and walking around the construction site freely. Since it is possible to confirm the details in detail, it is very easy to find even a few problems in the construction plan.
[0038]
In the present embodiment, the three-dimensional object data of all the work types included in the process table created by the process plan program 12 is read in advance into the walk-through program 16 and the layers and the respective work types managed by the walk-through program 16 are read. , And the interface program 14 instructs the walk-through program 16 on the layer associated with the work type at each time point, so that the walk-through program 16 displays the walk-through display only by overlaying the designated layers. The target 3D model can be constructed. That is, when starting the walk-through display of the construction status at the specified time, it is not necessary to read the data of the target 3D model from the file each time, so the processing becomes faster and the walk-through display is displayed. The operability when performing is greatly improved.
[0039]
As described above, according to the construction support system of the present embodiment, it is possible to display a screen as if the construction is being performed according to the construction plan and the user is observing while walking around the construction plan. The construction plan can be made much easier, and the construction plan support system can be used as a tool for explaining the construction plan to the customer. It will be easier to understand.
[0040]
In the above description, the CAD program 16 is incorporated in the construction plan support system 10, but the present invention is not limited to this, and three-dimensional object data created by a CAD program that operates on another computer system. May be read into the construction plan support system 10 via a network or via a recording medium such as a CD-ROM or DVD.
[0041]
In the above embodiment, the interface program 14 is read from the recording medium 1a into the computer system 1. However, the present invention is not limited to this, and the interface program 14 is transmitted from a server computer via a computer network such as the Internet. It may be downloaded to the computer system 1.
[0042]
【The invention's effect】
According to the present invention, while displaying the animation of the construction status that changes according to the progress of the construction, a walk-through display that freely moves the viewpoint within the construction status at an arbitrary time and freely changes the line-of-sight direction can be quickly displayed.
