Description

  The present invention relates to a three-dimensional object integration device.

  For example, when developing IT products such as a digital camera and a mobile phone, it is necessary to design software such as three-dimensional design, three-dimensional circuit board, circuit design, and IDE (Integrated Development Environment). In such product design, each of the above fields is designed using a unique design tool, and the design results are stored as, for example, three-dimensional CAD data, EDA data, or IDE data. For this reason, in most cases, there is no data compatibility between the fields. For example, in electronic circuit design, compatibility is maintained by a single provider until board production, but after board production is completed, there is almost no data exchange such as outline design / mold design, etc. Mutual information exchange was done verbally while looking at the printed paper to solve the problem.

  For this reason, although the external design of IT products has a great influence on purchasing motivation, the rework that the external design has on the electronic circuit design and the influence of the restrictions on the mounting of the electronic circuit on the external design process. There was a problem that the approach to examination and solution was not easy between different companies and different applications.

  The present invention has been made in view of the above-described conventional technical problems, and each of data in different file formats such as three-dimensional CAD data, EDA data, and IDE data created on a client computer on the design side is generally used. XML data exchanged over the network, converted to XML data that can be browsed, distributed to the server over the network, and received using common software that can display any of the 3D model, circuit diagram, IDE software, and text on the server The original 3D shape, 3D board shape, circuit diagram, IDE program can be individually displayed as multiple objects in the main screen from the data, and each of these objects can be rotated, moved, and scaled. Make other objects invisible for the object On the other hand, an object that is contained in any object and disappeared is made visible so that it can be seen, and the three-dimensional model of the product, the arrangement of the three-dimensional circuit board contained therein, and the circuit diagram of the three-dimensional circuit board An object of the present invention is to provide a three-dimensional object integration device that can show an IDE program executed by it in a nested manner, and conversely, draw each object from a nested state and show it as an independent object.

  The three-dimensional object integration device according to claim 1 displays three-dimensional model data for displaying a three-dimensional shape of an arbitrary product, circuit diagram data for displaying a circuit diagram of the product, and a three-dimensional circuit board of the product. Drawing means for displaying each of the three-dimensional model, circuit diagram, three-dimensional circuit board, and IDE program of the product as individual objects in one main screen from the three-dimensional circuit board data and the IDE program data of the product, Handling means for moving, rotating, and scaling operations on multiple objects displayed on the main screen, and a parent-child relationship with one object displayed on the main screen as a parent and another object as a child On the contrary, a parent-child relationship setting means for canceling the parent-child relationship is provided.

  According to a second aspect of the present invention, in the three-dimensional object integration device according to the first aspect, the parent-child relationship setting means has the three-dimensional model displayed in the main screen as a parent and the three-dimensional circuit board as a child. A parent-child relationship is set.

  According to a third aspect of the present invention, in the three-dimensional object integration device according to the second aspect, the parent-child relationship setting means uses the three-dimensional circuit board displayed in the main screen as a parent, and uses the circuit diagram as a child. It is characterized by setting a relationship.

  According to a fourth aspect of the present invention, in the three-dimensional object integration device according to the first to third aspects, when the parent-child relationship setting means sets a parent-child relationship in which a certain object is a parent and another certain object is a child, the child This object is made invisible as an object included in the parent object.

  According to the present invention, data in different file formats such as three-dimensional CAD data, EDA data, IDE data, etc., created in the development stage of one product is converted into common XML data and exchanged on the network, and the server The original 3D shape, 3D board shape, circuit diagram, and IDE program are individually displayed as multiple objects on the main screen from the XML data on the display device on the side, and the rotation, movement, and enlargement / reduction operations of each object are performed. In addition, it is possible to make one object contain another object and make it invisible, and conversely, to make an object that is contained in any object disappear and make it visible, so that the 3D of the product Model, arrangement of 3D circuit board included in it, circuit diagram of the 3D circuit board, IDE program executed by it Showed grams telescopically, also it can show as an object independent pull out each object from the nest state and vice versa, can serve as a tool for evaluating the sector of the design achievements of the product in an integrated manner.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows the configuration of an integrated product design support system according to an embodiment of the present invention. The integrated product design support system according to the present embodiment includes a data conversion apparatus 100 as a client installed in each design department, an integrated design editing apparatus 300 as a server installed in a design supervision department, and the data conversion apparatus. The system is configured by a network 200 that connects the 100 and the integrated design editing apparatus 300. The network 200 is a network using TCP / IP such as a LAN and the Internet.

  The data conversion apparatus 100 reads the product data, the design circuit CAD data, the software design data by IDE, the CAD data of the three-dimensional shape, and the CAD data of the three-dimensional mounting board in each design process, and converts them into Squeak format data. Alternatively, a data read / write unit 101 that outputs data obtained by the reverse conversion, a network communication unit 102 that performs XML-based communication by connecting to a network 200 such as the Internet or a LAN, and a squeak format data from the data read / write unit 101 Is converted into XML data for network communication and transmitted from the web communication unit 102, and the XML data received by the web communication unit 102 is converted back into data in the squeak format and passed to the data read / write unit 101. With That.

  The integrated design editing apparatus 300 is connected to a network 200 such as the Internet or a LAN to perform XML-based communication, and re-converts the content of XML data received by the network communication unit 301 into Squeak format data. An XML conversion unit 302 that performs reverse conversion, a drawing engine 303 that reproduces and displays the original three-dimensional product model, three-dimensional circuit board model, circuit diagram, IDE software, and text from the data in the Square format. A change operation, addition / deletion operation, movement operation, rotation operation, enlargement / reduction operation, and parent / child relationship in which an object is a parent and another object is a child Set and include the child object in the parent object Editing that affects the design side can be performed, such as operations that make it invisible, and operations that cause a child object that is invisible in an object to be released to appear as an individual object. The input includes a handling unit 304 that converts the data into Squak format data and returns it to the XML conversion unit 302, and a parent-child relationship setting unit 305 that sets the parent-child relationship between the objects and cancels the parent-child relationship.

  The integrated product design support system having the above configuration operates as follows. The data conversion apparatus 100 reads CAD data, IDE data, or text data generated by the circuits CAD, IDE, or three-dimensional CAD into the data read / write unit 101 and converts the data in the Squeak format, and the XML conversion unit 103 converts the data into XML. The data is converted into data, and data communication is performed with the integrated design editing apparatus 300 side through the network 200 based on the XML.

  This data conversion process is as follows. As shown in FIG. 2, CAD data CAD1 in a circuit diagram by EDA is circuit component data DT11, connection lines indicating how these circuit components are connected, and vector-format circuit data indicating connection states. The data is decomposed into DT12 and converted into binary data in Squeak format. The graphic of the circuit component in the circuit component data DT11 is decomposed into vector data of a connection line group representing the circuit component, and the connection line group, the connection state, and the component number are converted into binary data in Squake format. Further, as shown in FIG. 3, the data CAD2 of the three-dimensional circuit board by EDA is also decomposed into vector format component data DT21 and board data DT22, and these are similarly converted into Squeak format binary data. The part data DT21 includes data defining a three-dimensional shape together with the part number of the part. As for the CAD data of the three-dimensional shape of the product, the three-dimensional shape CAD data is decomposed into vector data, and further converted into binary data in the Squeak format. Further, the IDE data is as shown in FIG. 4, and the data read / write unit 101 reads the development project data, and develops a source file such as *. h, *. C, *. A file such as cpp is read and converted into data in Squeak format. These Squeak format data are converted into XML format data and transmitted to the integrated design editing apparatus 300 through the network 200.

  On the integrated design editing apparatus 300 side, screen display is performed in the croquet format by the following processing, and editing operation input for the screen display is made possible. In order to reflect the editing result, the integrated design editing apparatus 300 returns the data to the data conversion apparatus 100 via the network 200, where it is converted back to CAD data and IDE data by the reverse conversion process and distributed to CAD and IDE. Then, the result of the change is verified at this design site. This change result is converted into XML data in the same procedure as described above, retransmitted to the integrated design editing apparatus 300 side, and displayed on the screen.

  The XML data sent from the data conversion apparatus 100 via the network 200 is received by the network communication unit 301, re-converted into the original Squake format data by the XML conversion unit 302, and passed to the drawing engine 303. In the drawing engine 303, line extraction and solid figure extraction are performed by Square / Croquet, and as shown in FIG. 5, IDE data reproduction diagram 21, circuit diagram reproduction diagram 22, A three-dimensional board graphic 13 and a three-dimensional product graphic (not shown) are developed.

  The handling unit 304 includes a change operation, a join / delete operation, a move operation, a rotation operation, an enlargement / reduction operation, and a child object relative to a parent object with respect to a parent object with respect to one object and another object whose parent-child relationship setting unit 305 has set. The drawing engine 303 receives a drawing command corresponding to the drawing engine 303 by accepting an operation of making the object invisible and receiving an operation of releasing the invisible object contained in the object and making it visible as an individual object.

  This operation input is performed with respect to a graphic or text displayed on the screen 10 by the drawing engine 303 using a mouse or an equivalent operation device, and the three-dimensional board graphic 13 is rotated as shown in FIG. Thus, the other reproductions 21 and 12 of the project can be rotated together.

  Further, the handling unit 304 can edit the object on the screen 10, and as shown in FIG. 7, drag and drop the circuit component from the circuit component library on the circuit CAD side reproduced by Squeak and draw it on the circuit drawing. In addition, the circuit diagram can be produced by connecting the components with connection lines. Then, on the reproduction diagram of the circuit CAD diagram, it is possible to perform an editing operation to change, delete or add a corresponding part, or to add or delete a connection line. The circuit diagram edited on the overall design information editing apparatus 300 in this way is inversely converted into XML data, returned to the design source through the network 200 and the data conversion apparatus 100, and the CAD system of the circuit design department. The above change is made, the change result is converted into XML data by the above procedure, retransmitted to the integrated design editing apparatus 300 side, and redisplayed on the screen 10 as the change result.

  As for the IDE program, the source code can be edited based on XML by dragging and dropping the displayed file name as shown in FIG. This feedback is the same as described above and will be verified on the design side.

  The parent-child relationship setting unit 305 is a circuit diagram between a plurality of objects displayed on the screen, for example, between a three-dimensional circuit board object OB1 and its two-dimensional circuit diagram object OB2 as shown in FIG. When the object OB2 is dragged and superimposed on the circuit board object OB1, an inclusion relation is set between the two objects, and the circuit diagram object OB2 is included in the circuit board object OB1 and cannot be seen as shown in FIG. Can be handled. On the other hand, if the circuit board object OB1 is pointed in the display state of FIG. 9B to display an object inclusion dialog and the release of the inclusion object is indicated, the inclusion is made as shown in FIG. 9A. The circuit diagram object OB2 that has been stored can be displayed again. This can be similarly applied between a three-dimensional object of a product and a three-dimensional circuit board object incorporated therein.

  By the function of the handling unit 304, it is possible to compare the three-dimensional shape of a product usually designed in another department with the circuit board incorporated therein, and to compare the circuit board with the circuit diagram, thereby integrating the product design. Make it easy to make a good evaluation.

  The parent-child relationship setting canceling process by the parent-child relationship setting unit 305 is based on the flowcharts of FIGS. As shown in the flowchart of FIG. 10, in the state where at least two of the three-dimensional shape, three-dimensional circuit board, circuit diagram, and IDE program of the product on the screen are displayed by the drawing engine 303 (step S11), the handling unit An operation is performed by dragging an object through 304 (step S13), and an instruction is given to set a parent-child relationship when a state of contact with another certain object continues for a certain period of time (steps S15 and S17). The drawing engine 303 side sets a parent-child relationship based on this information (step S19). If the parent-child relationship is set in this way, as shown in FIG. 6, if the parent object is selected and rotated and moved, other objects with the parent-child relationship can be rotated, moved, and enlarged / reduced simultaneously. become.

  As shown in the flowchart of FIG. 11, when the cursor is placed on a certain object set as a parent and double-clicked (step S21), a menu dialog is displayed (step S23). If an item to add a child object is selected from this dialog and the child object is selected, the child object is added to the parent object (step S25). Similarly, in the menu display (step S23), an item to add a display object is selected, and the display object is added by selecting the corresponding object (step S27).

  Further, in the menu display of step S23, by selecting an item containing a child object and selecting the corresponding object (step S29), the object set as the child object is included in the parent object and is not visible on the screen. (Steps S31 and S33). Furthermore, in the menu display (step S23), an item for separating the child object is selected (step S35), and an instruction to separate the displayed child object is passed to the drawing engine 303 side (step S37). Is released (step S39). By releasing this parent-child relationship, it becomes possible to operate for each object.

  As shown in the flowchart of FIG. 12, when the parent-child relationship is set and the child object is displayed in a state of being included in the parent object, by selecting the parent object and double-clicking (Step S41), the menu is displayed. A dialog is displayed (step S43). If an item for displaying a child object is selected from the dialog, the child object is released and displayed (steps S45 to S49). When a child object is selected and rotated or moved, it can be operated alone. On the other hand, by operating the parent object in a state where both the parent object and the child object for which the parent-child relationship is set are displayed, the parent and child objects can be rotated and moved.

  Next, an integrated product design support system according to an embodiment of the present invention will be described. This system implements Square 3.5 and multilingual environment. This Square can operate almost all resources on the computer. In addition, Squeak has a rich Internet interface, and various packages related to Squeak exist, so that an optimum environment can be easily realized. In order to integrate the information of the embedded software from the electronic circuit design, the embedded UML technique is adopted. This embedded UML technique can consistently handle electronic circuit design, electronic board design, and embedded software development.

  As an example of product design, the design of an ear thermometer shown in FIG. 13 will be described. In the case of the ear-type thermometer, the number of parts is small and only four ICs are mounted. When this is expressed in UML, an actor is shown in FIG.

  In this case, the user is displayed as a single actor, the button / liquid crystal is a user interface, and the mechanism is a sensor as a sub-actor. Each sub-actor is a hardware implementation, and this part is easily affected by design and product life at the production site. Further, if the mechanism area is regarded as one package, an analysis as shown in FIG. 15 is possible.

  Squire has already implemented Jakaranda of Hern Tylim as a package of UML editor. By utilizing it, the UML editor part has been strengthened, and scroll and scale have been added to correspond to a large circuit diagram.

  For handling circuit diagrams and software, an eParts Browser as shown in FIG. 16 is implemented. With these, the actual device class can be handled at the component / schematic level and the software associated therewith can be called. For components, a circuit diagram can be created using a UML package or the like as a sheet. It is also possible to verify whether it functions correctly by means of a circuit evaluation system on EDA.

  As an HTTP interface based on XML, an HTTP interface was also implemented on Squeak. In addition, Masashi Umezawa's SIXX was combined to exchange data on an XML basis. An example of directory information communication based on XML is shown in FIG.

  As a result, a normal Internet browser can visualize the component, circuit diagram, board information, C source, header file, MAKE file, etc. using XML as shown in FIG.

  The relationship between Square, EDA, and embedded software development environment in this implementation is a software wrapping relationship. In other words, the electronic circuit engineer does not need to give up the EDA environment that he / she is accustomed to, and the software engineer is not easily affected by how the IDE and the target CPU are changed. In other words, this system is a software front-end implementation that handles data directly, and it can easily adapt to a new environment with only a few class changes responsible for interfacing with data. A project on Squak can be handled by Croquet, and can be operated on Croquet without changing the module as shown in FIG. Of course, it is also possible to exchange component information via the Internet.

  As a result, embedded UML allows circuit designers, software engineers, and project managers to handle data consistently, and in particular, project managers can clearly capture, visualize, and package their assets. . Even if legacy circuit design software and embedded development software are used remotely and in any environment, they can be easily grasped and analyzed by embedded UML. This is due to the extremely seamless operation of the Square / Croquet environment. In addition, since data packaging in Croquet makes it possible to handle all data in the Croquet environment, a circuit diagram and necessary software are bound to the designed board 3D shape and visualized as shown in FIG. It is now possible to create “equipment data containers”. All users who have jointly installed these packages in the same space can import them into their own projects and verify them.
