  However, even when multiple workers collaborate, when multiple workers review problem areas for a single design, such as a design review, for example, a problem from multiple workers Even if the parts are presented all at once, it will only cause confusion and will not proceed.

  An object of the present invention is to provide a design review support method, a program, and a system in which a plurality of workers can efficiently perform a review with respect to a design review in which a problem portion is reviewed for one design. is there.

  The design review support method according to the first aspect of the present invention provides an editing authority for another terminal designated as one of the plurality of terminals when the design review is performed using the plurality of terminals. In a method of executing a process for supporting design / review in cooperation between a first terminal capable of determining the relationship and a second terminal to which editing authority is given from the first terminal, the first terminal When data on an existing application is changed on the terminal side, the data is converted into image data of a predetermined format, and the converted data on the existing application is transmitted to another terminal and received from another terminal. The image data thus displayed is displayed in an area corresponding to the other terminal, a signal for turning on or off the editing authority is transmitted to the designated terminal, and the editing authority is turned on at the second terminal side. When the signal to turn off is received, the editing mode of the data on the existing application is changed, and when the data on the existing application is changed, the data is converted into image data of a predetermined format, A design / review support method characterized by transmitting the converted data on an existing application to another terminal and displaying image data received from the other terminal in an area corresponding to the other terminal.

  Here, when the second terminal receives a signal for turning on the editing authority from the first terminal capable of defining the editing authority, the editing mode during operation of the existing application of the second terminal is changed. For example, since the data of an existing application can be edited, it is easy to avoid a situation in which a problem portion of a design is presented simultaneously or substantially simultaneously by a user of a large number of terminals (review participants), and an efficient design is performed.・ Review can be performed.

  In the first aspect, the editing mode is changed to a mode in which, when a signal for turning on the editing authority is received, only the problem area marking process can be performed on the data on the existing application. If a signal for changing the editing authority to OFF is received, the data on the existing application may be changed to a mode that disables all editing functions.

  In this case, on the second terminal side to which the editing authority is granted, editing of the existing application data other than the marking process for the problem location is performed in any mode in which the operation mode of the existing application is switched. Is impossible. Therefore, it is possible to avoid a situation in which the review of the application is erroneously corrected by the user of the second terminal and the review is confused, and the design review can be performed efficiently.

  The design / review support program according to the second aspect of the present invention includes a first terminal capable of defining editing authority for another terminal designated as one of a plurality of terminals, and the first terminal. When a design review is performed in cooperation with a second terminal to which editing authority is granted from a terminal, the attributes of the specified own terminal are specified in a program that allows each terminal to support design review. A function specifying step for specifying an editing mode during operation of an existing application, and a data conversion step for converting the data into image data of a predetermined format when data on the existing application is changed, A step of transmitting the converted data on the existing application to another terminal; and a step of transmitting image data received from the other terminal to the other terminal. A screen composition step to be displayed on the screen, a step of transmitting a signal for turning on or off editing authority to a designated terminal, and a signal for turning on or off the editing authority based on the attribute of the designated terminal. And a step of enabling or disabling the transmission function of the design review support program.

  Here, when the attribute of the own terminal is the first terminal capable of determining the editing authority, if the signal transmission function for turning on or off the editing authority is enabled, the first terminal is enabled. When the second terminal receives a signal for turning on the editing authority from one terminal, the editing mode during operation of the existing application of the second terminal is changed. For example, data of the existing application can be edited. Therefore, it is easy to avoid situations where design problems are presented simultaneously or substantially simultaneously by users (review participants) of a large number of terminals, and design review can be performed efficiently.

  The design / review support system according to the third aspect of the present invention has an editing authority for another terminal designated as one of the plurality of terminals when the design / review is performed using the plurality of terminals. In a system for supporting design / review in cooperation with a first terminal capable of determining a user ID and a second terminal to which editing authority is granted from the first terminal, the first terminal A function designating unit that designates the editing mode during the operation of the application as the first mode, a data conversion unit that converts the data into image data of a predetermined format when data on the existing application is changed, Transmission means for transmitting the converted data on the existing application to the other terminal, and a screen composition method for displaying the image data received from the other terminal in an area corresponding to the other terminal And an editing authority on / off instruction means capable of instructing other terminals to turn on / off the editing authority, and the second terminal sets an editing mode during operation of the existing application. A function specifying means for specifying the second mode; a function changing means for changing the mode of operation of the existing application to the third mode when a signal for turning on the editing authority is received; When data on the application is changed, data conversion means for converting the data into image data of a predetermined format, transmission means for transmitting the converted data on the existing application to other terminals, and from other terminals A design / review support system comprising: a screen composition unit for displaying received image data in an area corresponding to the other terminal.

  Here, when the second terminal receives a signal for turning on the editing authority from the first terminal capable of determining the editing authority, the editing mode during operation of the existing application of the second terminal is the first. Since the mode (2) (for example, the mode for disabling the editing function) is changed to the third mode (for example, the mode for enabling only the marking process of the problem part), it is simultaneously performed by the users (review participants) of many terminals. Or, at the same time, it is easy to avoid a situation where a design problem is presented, and the design review can be performed efficiently.

  According to the present invention, when a terminal to which editing authority is turned on receives a signal for turning on editing authority from a terminal capable of defining editing authority, the operation of an existing application of the terminal to which the editing authority is granted Since the editing mode at the time is changed, for example, data of an existing application can be edited, it is easy to avoid a situation where a design problem portion is presented simultaneously or substantially simultaneously by a plurality of terminal users (review participants). Become.

  Further, according to the present invention, on the terminal side to which editing authority is given, the mode at the time of operation of the existing application is any mode that can be switched. Cannot be edited. Therefore, it is possible to avoid a situation where the review is confused by the user of the terminal to which the editing authority is given by making corrections to the application data.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a schematic configuration diagram of a design / review support system according to an embodiment of the present invention when two terminals are provided.

  In FIG. 1, the design / review support system is configured by connecting a first terminal 1 and a second terminal 2 via a communication medium 4. Each of the first and second terminals includes a design / review support unit (attribute designation unit 11, function designation unit 12, editing authority on / off instruction unit 13, data conversion unit 14, and screen composition unit 15). Prior to performing the design review, it is determined in advance between users which terminal from a plurality of terminals is a terminal that can determine editing authority for other terminals. A terminal other than the terminal that can determine the editing authority is a terminal to which the editing authority is given from the terminal that can determine the editing authority. For example, in FIG. 1, if the first terminal 1 is determined as a terminal that can determine the editing authority, the second terminal 2 becomes a terminal to which the editing authority is given from the first terminal 1.

  When designing and reviewing using N terminals, one of them is designated as a terminal that can define editing authority for other terminals, and the remaining (N-1) terminals are designated. The terminal is a terminal to which editing authority is given from a terminal that can determine the editing authority.

  FIG. 2 is a block diagram showing the configuration of the design / review support unit 10 of the terminal that can determine the editing authority. In FIG. 2, the design / review support unit 10 includes an attribute designation unit 11, a function designation unit 12, an editing authority on / off instruction unit 13, a data conversion unit 14, and a screen synthesis unit 15.

  Note that the user sets the attribute of the terminal through the attribute specifying unit 11 as “a terminal that can determine editing authority for all other terminals” or “terminal to which editing authority is granted”. Specify. As described above, prior to the design / review, it is decided that the terminal having the design / review support unit 10 in FIG. Therefore, in accordance with the agreement, the user of this terminal designates his / her terminal as “a terminal capable of determining editing authority for all other terminals” via the attribute designation unit 11.

  Based on this designation, a function designation signal is output from the attribute designation unit 11 to the function designation unit 12. Based on this function designation signal, the function designation unit 12 performs a marking process of a problem location and other editing processes as an editing mode when the existing application 21 started from the design / review support unit 10 is operated by the user. Specifies a possible mode (for data 22 on existing application 21). The existing application 21 is an existing word processor, spreadsheet software, CAD software, or the like.

  Based on this designation, an enabling signal is output from the attribute designation unit 11 to the editing authority on / off instructing unit 13 to instruct other (all) terminals to turn on / off the editing authority. The function of the edit authority on / off instructing unit 13 that can be set is set to “valid”.

  When the data 22 is changed on the existing application 21 and the screen display is changed, the data conversion unit 14 determines whether or not the data 22 has been changed when the data 22 is saved along with the change of the screen display. Regardless of the time, it is activated by a predetermined trigger such as every predetermined time interval, and the data 22 is converted into image data (bitmap, JPEG, etc.) 23 in a predetermined format.

The image data 23 is transmitted via the transmission unit 26 to all other terminals that perform design / review (addresses of these terminals are acquired in advance).
Also, as described above, in this terminal, the function of the editing authority on / off instruction unit 13 is set to “valid” by the user's designation. Thus, a signal for turning on the editing authority can be transmitted to the designated terminal from all other terminals that perform the design review via the transmission unit 26.

On the other hand, the image data 24 from another terminal is received via the receiving unit 27, and is output and displayed in the area corresponding to the other terminal (transmission source terminal) by the screen composition unit 15.
FIG. 3 is a block diagram showing a configuration of the design / review support unit 30 of a terminal to which editing authority is given from a terminal that can define editing authority. In FIG. 3, the design / review support unit 30 includes an attribute designation unit 11, a function designation unit 12, an editing authority on / off instruction unit 13, a data conversion unit 14, a screen synthesis unit 15, and a state change output unit 16.

  As described above, prior to the design / review, the terminal having the design / review support unit 30 in FIG. 3 is given the editing authority from the terminal that can set the editing authority with respect to other terminals. In accordance with the agreement, the user of this terminal designates the terminal as the “terminal to which editing authority is granted” according to the agreement.

  Based on this designation, a function designation signal is output from the attribute designation unit 11 to the function designation unit 12. Based on this function designation signal, the function designation unit 12 sets the editing mode during operation of the existing application 21 activated by the user from the design / review support unit 30 (for data 22 on the existing application 21). ) Specify a mode that disables all editing functions. The existing application 21 is an existing word processor, spreadsheet software, CAD software, or the like.

  Also, based on this designation, an invalidation signal is output from the attribute designation unit 11 to the editing authority on / off instructing unit 13 to instruct other (all) terminals to turn on / off the editing authority. The function of the edit authority on / off instructing section 13 that can be set is set to “invalid”.

  When the data 22 is changed on the existing application 21 and the screen display is changed (when marking processing is performed), the data conversion unit 14 stores the data 22 with the change of the screen display. When the data 22 is changed, the data 22 is activated by a predetermined trigger such as every predetermined time interval regardless of whether the data 22 is changed, and the data 22 is converted into image data (bitmap, JPEG, etc.) 23 in a predetermined format.

The image data 23 is transmitted via the transmission unit 26 to all other terminals that perform design / review (addresses of these terminals are acquired in advance).
On the other hand, the image data 24 from another terminal is received via the receiving unit 27, and is output and displayed in the area corresponding to the other terminal (transmission source terminal) by the screen composition unit 15.

  When a signal for turning on the editing authority is received via the receiving unit 27, the signal is input to the state change output unit 16 and the function specifying unit 12. In the function designating unit 12, when the signal for turning on the editing authority is input, the editing mode at the time of operation of the existing application is changed from “mode in which all editing functions are disabled” to “marking function only is enabled”. Change to "Mode". In addition, in the state change output unit 16, when the signal for turning on the editing authority is input, the editing mode is changed to “mode in which only the marking function is enabled” in the message display area on the screen. Output a message to that effect.

  When a signal for turning off the editing authority is received via the receiving unit 27, the signal is input to the state change output unit 16 and the function specifying unit 12. In the function designating unit 12, when the signal for turning off the editing authority is input, the editing mode at the time of operation of the existing application is changed from “mode in which only the marking function is enabled” to “all editing functions are disabled. Change to "Mode". Further, in the state change output unit 16, when a signal for turning off the editing authority is input, the editing mode is changed to “mode in which all editing functions are disabled” in the message display area on the screen. A message indicating that this has occurred is output.

  In this embodiment, as shown in FIG. 4, each terminal that performs design / review of data used for an existing application from, for example, the database 45 that holds 3D-CAD data via the server device 43. (In the figure, it is acquired in advance by terminal 1 and terminal 2). Needless to say, existing applications are also installed in each terminal in advance.

FIG. 5 is a diagram illustrating an example of a display screen of two terminals (PC1 and PC3) when performing design review with three terminals.
In FIG. 5, the terminal PC1 corresponds to, for example, a terminal that can define editing authority for the other terminals described above, and the terminal PC3 corresponds to a terminal to which editing authority is given from the terminal PC1.

  For the terminal PC1, the screen composition unit 15 of the design / review support unit 10 of the terminal PC1 causes the image data from other terminals (terminal PC2, PC3) to be displayed in the area for displaying the image data from the PC2 and PC3 (PC2). , An area corresponding to PC3) and displayed (pasted). In addition, the display screen of the existing application 21 is displayed on the display screen of the PC 1 because the existing application 21 is activated on the design / review support unit 10 according to the user's instruction. In the figure, through the subsequent data selection process, the display screen of the existing application 21 is displayed including the data 22 of (application 21).

  For the terminal PC3, the screen composition unit 15 of the design / review support unit 30 of the terminal PC3 causes image data from other terminals (terminals PC1 and PC2) to be displayed in an area for displaying the image data from the PC1 and PC2. It is output and displayed (pasted) in (area corresponding to PC1, PC2). In addition, it is not certain from the figure that the signal for turning on the editing authority is received from the terminal PC 1 and the editing mode at the time of operation of the existing application 21 is changed to “mode in which only the marking function is enabled”. However, in the message display area on the display screen of the PC 3, a message “Application editing mode has been changed to“ mode with only marking enabled ”” is displayed. That is, the display screen (including data 22) of the existing application 21 is in an editable state for the marking process.

  FIG. 6 is an example of data of an existing application used for design review. FIG. 6 shows a lens structure. In this lens structure, the first lens is fixed to the first lens barrel via an adhesive, and the second lens barrel is installed so as to be slidable inside the first lens barrel. Yes. The second lens and the third lens are fixed to the second lens barrel via an adhesive. In the figure, L indicates the fitting length between the first lens barrel and the second lens barrel.

  FIG. 7 is a diagram showing an operation example of the design / review support system of the present embodiment. In FIG. 7, the first terminal is a terminal that can define editing authority for other terminals, and the second terminal is a terminal to which editing authority is given from the first terminal. For example, in the case of a three-terminal configuration (PC1, PC2, PC3), if PC1 is the first terminal, either PC2 or PC3 is the second terminal.

  In FIG. 7, for example, when performing the design review using the data shown in FIG. 6, the editing authority is turned on for the second terminal so as to hear the opinion of the user of the second terminal from the first terminal. A signal for turning on the editing authority is transmitted in (1) via the off instruction unit 13.

  This signal travels on the network in (2), is received by the second terminal in (3), and is input to the function designating unit 12 of the second terminal. Then, the editing mode at the time of operation of the existing application 21 is changed from this function specifying unit 12 to a mode that enables only the marking process (for the data of the existing application). Then, for example, a marking process as shown in FIG. 8 is performed on the data 22 on the existing application 21 by the user. In addition, the marking of FIG. 8 has shown that the space | interval between the 1st lens barrel and the 2nd lens barrel, or the fitting length L is inappropriate, for example.

  In (4), when the data is changed (updated) as a result of the marking process, the data conversion unit 14 is activated in (5) with the change or saving accompanying the change as a trigger, and the changed data Are converted into image data of a predetermined format. This image data is transmitted to all the other terminals that are conducting the design review in (6). Of course, the first terminal is included in these transmission target terminals.

  The (update) information of this image data is transmitted over the network in (7), for example, received by the first terminal in (8), and corresponds to the terminal (in this case, the second terminal) that transmitted the image data. The screen display to be updated is updated (changed) by the screen composition unit 15.

  In the present embodiment, the first terminal that can determine the editing authority transmits a signal for turning on the editing authority to one other terminal. Alternatively, a signal for turning on the editing authority may be transmitted to a plurality of terminals.

  In addition, the first terminal that can set the editing authority transmits a signal to turn off the editing authority to the terminal that has been given the editing authority, thereby turning off the editing authority of the terminal that has been granted the editing authority. Can be reset to When the editing authority is turned off at a terminal to which editing authority is given, the data 22 on the existing application 21 cannot be edited (changed).

  Note that the editing authority on / off instructing unit 13 of the first terminal turns on the editing authority for all other terminals while the image data is not received after the signal to turn on the editing authority is transmitted. The on-signal transmission function is disabled so that a signal to be transmitted cannot be transmitted, and the editing authority is turned off for the terminal (second terminal) that transmitted the image data, triggered by the reception of the image data. Is transmitted to the existing application data at any point in time, the two terminals (the first terminal that can define the editing authority, the editing authority 1 Only one terminal) exists as a data-editable terminal. In this case, if the terminal other than the two sets an opinion on the marking information for the data (sends the opinion as data), etc., the design / review is conversely under a situation where the editing authority is limited to two. (Everyone can express their opinions all at once (presenting a marking proposal) and avoid being out of control).

  In addition, as shown in FIG. 5, when designing and reviewing with three terminals, it is possible to display screens corresponding to all terminals at once, but when there are many terminals that perform design and review, Various display methods as shown in FIG. 9 can be employed as a display method of a screen display unit (not shown) provided in the design / review support unit of FIG. 2 or FIG.

  In FIG. 9A, a child window of MDI (Multiple Document Interface) is set as an area for displaying a design (data) 41 to be reviewed corresponding to each terminal, and each child window is designated by specifying each of the child windows. The display area of the design (data) to be reviewed corresponding to the terminal is switched.
