[0018]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0019]
FIG. 1 is a conceptual diagram showing a configuration of a design data providing system according to the present invention. The design data providing system of the present invention includes a design data creation system 2 provided in the design data creation center 20 and a design data analysis system 3 provided in the design data analysis center 30. As shown in FIG. 1, the design data creation system 2 and the design data analysis system 3 include a personal computer (hereinafter referred to as a PC) 1 operated by a customer C who is a construction client of a building such as a building and a condominium, and the Internet. Connected to the communication network NTW. Therefore, the PC 1, the design data creation system 2, and the design data analysis system 3 can perform data communication with each other via the communication network NTW. The design data creation system 2 and the design data analysis system 3 are connected to a dedicated line PN in addition to the communication network NTW, and data communication can be performed via the dedicated line PN.
[0020]
In the present embodiment, the design data creation system 2 and the design data analysis system 3 are provided in different centers, but a configuration in which both systems are installed in one center may be employed.
[0021]
The customer C mentioned above requests creation of a design document for a building from a designer 40 such as an architectural design office or a construction company when performing a construction work. Here, the design book refers to the drawings and specifications necessary for carrying out the construction work of the building, for example, a list diagram as shown in FIG. 2, a framework diagram as shown in FIG. It is. In some cases, the customer C himself / herself is the designer 40. In this case, however, the customer C creates a design book.
[0022]
The above-mentioned list is a list in which information such as cross sections and dimensions of building components such as columns, walls, and beams is written in a predetermined frame, and the positional relationship between the components shown in the list. This is a drawing composed of a plan view. FIG. 2A shows an example of a list related to columns, and FIG. 2B shows an example of a plan view showing the positional relationship between the columns shown in the list.
[0023]
The axis diagram is a drawing showing a frame of a wall composed of a base, a column, a brace, and the like as an elevation. FIG. 3 shows an example of a framework diagram representing a framework of a three-story building.
[0024]
In addition to the list diagram and the axis diagram, the design book B includes a detailed core diagram for determining the center position of pillars, walls, etc., and the structure of each floor of the building. Specifications such as floor plan to show, drawings such as other quadrangle maps, floor plans, detailed stairs, and joinery table are included.
[0025]
When the customer C obtains the design book B as described above from the designer 40, the customer C provides the design book B to the design data creation center 20 by mail or hand delivery. At this time, the customer C notifies the design data creation center 20 of an e-mail address that the customer C can use. When the design book B is electronic data, the electronic data may be provided to the design data creation center 20 by transmitting the electronic data to the design data creation system 2 using the PC 1.
[0026]
When the design data creation center 20 receives the design book B from the customer C, the design data creation center 20 inputs the received design book B to the design data creation system 2 and displays the design data representing the building related to the design book B as a three-dimensional shape. Let it be created.
[0027]
In addition, when the design data analysis system 3 provided in the design data analysis center 30 receives the design data created by the design data creation system 2, it calculates the dimensions and quantity of the building components based on the design data. Various analysis processes are performed.
[0028]
FIG. 4 is a block diagram showing a configuration of the design data creation system 2. The design data creation system 2 has a CPU 201, which controls each hardware 202 to 207 described later and executes a computer program stored in the hard disk 203.
[0029]
The RAM 202 is configured by, for example, SRAM or DRAM, and stores temporary data generated when the computer program is executed. The hard disk 203 is composed of a readable / writable magnetic disk or the like, and stores various computer programs and various data necessary for the operation of the design data creation system 2.
[0030]
The input unit 204 includes a keyboard and a mouse, and is used by an operator to give various instructions to the design data creation system 2. The display 205 is a display device composed of a CRT or LCD, and displays various input / output data.
[0031]
The communication I / F 206 is an interface used to connect to the communication network NTW and the dedicated line PN, and is configured by, for example, a modem, a DSU (Digital Service Unit), a NIC (Network Interface Card), or the like.
[0032]
The scanner 207 is an image reading device used for converting data shown on a paper medium into electronic data using a CCD (Charged Coupled Device) or the like.
[0033]
The hard disk 203 described above has the following three databases (design book data DB 203a, three-dimensional design data DB 203b, and format data DB 203c).
[0034]
The design book data DB 203a as the first database stores design book data obtained as a result of digitizing the design book B as described later.
[0035]
The 3D design data DB 203b, which is a second database, stores 3D design data created as described later based on the design book data. This three-dimensional design data expresses the building shown in the design book data as a three-dimensional shape. Specifically, it is composed of information relating to the shape, arrangement, dimensions, and accommodation of each component of the building, such as a pillar, wall, and beam.
[0036]
The format data DB 203c, which is a third database, stores format data related to the format of design books. Here, the format data refers to information indicating how design information is represented in the design book. This format data is created in advance for each design document such as a list diagram and a shaft diagram. For example, the format data for the list diagram is composed of information indicating what is written in each frame in the list as shown in FIG.
[0037]
Next, the operation of the design data providing system of the present invention will be described.
[0038]
FIG. 5 is a flowchart showing a processing procedure of the design data creation system 2 accompanying creation of the three-dimensional design data. The design data creation system 2 creates image data in a TIFF (Tagged Image File Format) format by reading the design book B received from the customer C with the scanner 207 (S101). This image data is stored in the RAM 202.
[0039]
Next, by performing raster / vector conversion on the image data stored in the RAM 202, design book data capable of distinguishing and recognizing figures, characters, numerical values, etc. is created (S102). This design book data is created, for example, in DXF (Drawing Interchange File) format. The design book data created in this way is registered in the design book data DB 203a (S103).
[0040]
Next, the contents of the design book data registered in the design book data DB 203a are determined with reference to the form data stored in the form data DB 203c. Specifically, for example, with reference to the format data for the list diagram, it is determined what information is displayed in which frame in the list indicated in the design book data. As a result, data (hereinafter referred to as attribute data) relating to the attributes (dimensions, arrangement, bonding state with other structural members, etc.) of each structural member of the building is acquired (S104).
[0041]
By the way, as described above, various kinds of drawings are included in the design book, and attribute data of the same constituent member is shown in each of the drawings. However, it is due to an error of the designer 40 who created the design book. Due to this, the attribute data of one component member may differ depending on the drawing. In such a case, which attribute data is correct is determined by comparing the attribute data shown in each drawing with each other. As a result, correction processing is executed on the design book data indicating attribute data having a value different from that of the attribute data determined to be correct so as to be correct attribute data (S105). If the attributes of the constituent members are the same in all drawings, such correction processing is unnecessary, and it goes without saying that the process proceeds to step S106 without executing step S105.
[0042]
Based on the attribute data of the component acquired as described above and corrected as necessary, three-dimensional design data reflecting the dimensions, arrangement, joining state, etc. of each component is created (S106), The created 3D design data is registered in the 3D design data DB 203b (S107). FIG. 6 shows an example of the three-dimensional design data registered in this way.
[0043]
The three-dimensional design data shown in FIG. 6 relates to a plan view showing the configuration of one floor. In this plan view, circled symbols (X1, X2, etc.) are for specifying the core and are data acquired from the above-described detailed core diagram. Moreover, although the distance between each street core is represented as numerical data, these numerical data are acquired from the floor plan view or the like described above.
[0044]
In addition, by performing the same process as the process described above, three-dimensional design data relating to a plan view, a front view, a side view, and the like showing the structure of the building is created.
[0045]
The attribute data as described above is associated with each component in the drawing indicated by such three-dimensional design data. Then, the three-dimensional design data can be easily corrected by changing the value of the attribute data. Therefore, the three-dimensional design data can be reused when a construction drawing is subsequently created. Such correction processing will be described later.
[0046]
The design data creation system 2 creates an e-mail with the 3D design data registered in the 3D design data DB 203b as attached data, and sends the e-mail to an e-mail address previously communicated by the customer C. (S108). As a result, the customer C can receive the electronic mail using the PC 1 or the like, and can acquire the three-dimensional design data attached to the electronic mail.
[0047]
The 3D design data is not provided to the customer C using e-mail in this way, but is provided by performing data communication based on, for example, HTTP (HyperText Transfer Protocol) or FTP (File Transfer Protocol). Of course, you may do it.
[0048]
Further, when the customer C desires, the design data creation system 2 may transmit the three-dimensional design data to the design data analysis system 3. In this case, the design data creation system 2 transmits the three-dimensional design data to the design data analysis system 3 via the dedicated line PN.
[0049]
Next, the correction process described above will be described. FIG. 7 is a flowchart showing a processing procedure of the design data creation system 2 associated with the correction of the three-dimensional design data. First, the operator displays the three-dimensional design data to be corrected on the display 205 provided in the design data creation system 2. Thereby, for example, three-dimensional design data as shown in FIG. 6 is displayed on the display 205. Here, by operating the input unit 204, the operator moves a pointer (position on the display) on a structural member whose attribute information needs to be changed among structural members of the building indicated in the three-dimensional design data. Move the mark).
[0050]
The design data creation system 2 acquires the position information of the pointer moved by the operator (S201). Then, based on the acquired position information, it is determined which structural member the pointer points to, and the structural member for which the operator wants to change the attribute information is specified (S202).
[0051]
The attribute data of the component specified as described above is acquired by referring to the three-dimensional design data displayed on the display 205 (S203). Then, the acquired attribute data is displayed using a window as shown in FIG. 8 (S204).
[0052]
The window shown in FIG. 8 displays column attribute data identified by the symbol C1. Such a window is prepared for each component so that items necessary for representing the attribute data of each component can be displayed. The operator refers to the attribute data displayed in the window and selects items to be changed. Then, new data is input to the selected item.
[0053]
If the operator determines that the pointer has moved by operating the input unit 204 (YES in S205), the design data creation system 2 ends the process. On the other hand, if it is determined that the pointer has not moved (NO in S205) and the confirm button on the window shown in FIG. 8 has been clicked (YES in S206), the attribute data is corrected based on the newly input data. In step S207, the three-dimensional design data including the attribute data corrected as described above is registered in the three-dimensional design data DB 203b. Thereby, the correction process is completed.
[0054]
If it is determined that the pointer has not moved (NO in S205) and the confirm button has not been clicked (NO in S206), the system waits until any of these events occurs due to an input operation by the operator. Will do.
[0055]
The customer C can obtain the three-dimensional design data by receiving the electronic mail transmitted from the design data creation system 2 as described above using the PC 1. And when it becomes necessary to perform various analyzes regarding the building shown in this 3D design data, the customer C creates an e-mail with the 3D design data as attached data using the PC 1. In the body of this e-mail, type data indicating the type of analysis desired by the customer C (for example, output of integration, creation of a processing book, etc.) and an e-mail address that is the destination of analysis data indicating the result of analysis are input. ing.
[0056]
FIG. 9 is a flowchart showing a processing procedure of the design data analysis system 3 accompanying creation of analysis data. The design data analysis system 3 receives the electronic mail created as described above, and acquires three-dimensional design data that is attached data of the electronic mail (S301). Next, the type of analysis is specified by referring to the type data input in the body of the received e-mail (S302).
[0057]
As described above, since the three-dimensional design data includes the attribute data of each component member, various analysis processes can be executed by using the attribute data. Specifically, for example, when integrating the housing area as an analysis process, the surface area of each constituent member is calculated. It is also possible to estimate the cost required for the construction based on the calculated frame area.
[0058]
The design data analysis system 3 executes analysis processing based on the acquired three-dimensional design data according to the type specified in step S302, and creates analysis data indicating the result (S303). 10 and 11 show an example of analysis data created in this way.
[0059]
The analysis data in FIG. 10 shows the results when a workbook is created as analysis processing. Here, the processing book refers to a collection of data necessary for producing a formwork (a temporary framework for placing concrete). Such a processing book can be easily obtained from the dimension values of the constituent members. Moreover, the analysis data of FIG. 11 has shown the result at the time of integrating | accumulating a housing area as an analysis process. As shown in FIG. 11, the result of this integration is represented by an integration table T compiled for each floor of the building.
[0060]
The design data analysis system 3 stores the analysis data created in this way in the storage device of the design data analysis system 3 (S304), and sends the received e-mail with the analysis data as attached data. The e-mail address input in the body of the message is transmitted as the destination (S305).
[0061]
The customer C can acquire the analysis data by receiving the electronic mail transmitted from the design data analysis system 3 as described above using the PC 1.
[0062]
If an e-mail is transmitted from the design data creation system 2 to the design data analysis system 3 without going through the customer C, in step S305, not only the analysis data but also the three-dimensional design data is added to the attached data. Will send an e-mail. Thereby, the customer C can acquire both the three-dimensional design data and the analysis data.
[0063]
As described above, the present invention provides the customer C with the three-dimensional design data and analysis data relating to the building, but it can also be applied to various industrial products, for example, in addition to the building. .
[0064]
