Description

  The present invention relates to a technology of an information management system that manages information related to product planning, development, design, manufacture, sales, maintenance, and the like as electronic information.

In recent years, a PDM (Product Data Management) system for efficiently managing information related to design associated with product development has been introduced. This PDM system is a document that includes CAD data (computer aided design data) such as drawing data of various parts related to product design and part information created by a client terminal connected to the server apparatus and connected to the server apparatus through a network. Information is associated and stored in a tree format (see, for example, Patent Document 1).
JP 2000-113007 A

  However, the information management system in which the conventional PDM system having such a configuration is introduced has the following problems.

  In other words, when the PDM system in the conventional system is managed using CAD data and document data, which are design drawings created in product development and design, revisions are made each time a design change / correction or prototyping is performed. The data is stored in the storage area of the server device while maintaining the association of the document data. If the final specification is determined in the process in which such a drawing is changed, the prototype drawing may be used as the formal drawing as it is without being revised to the formal drawing. In such a case, when multiple workers individually refer to the design drawings via the client terminal, it is difficult to determine whether the registered design drawing is a prototype drawing or a formal drawing. Inconvenience has occurred.

  In addition, to identify prototype drawings and formal drawings, even if the prototype drawing is determined to be adopted as a formal drawing, an individual registration number is assigned to the formal drawing and registered individually. The registered data is registered and managed. Therefore, there is a problem in that data having the same content is duplicated for each part, the amount of data increases rapidly, and management becomes complicated.

  The present invention has been made in view of such circumstances, and has a small data capacity and enables efficient browsing of registered electronic information while clarifying a change history of electronic information. The main purpose is to provide a management system.

In order to achieve such an object, the present invention has the following configuration.
That is, the first invention is an information provided with a client terminal that creates various electronic information, and a server device that is connected to the client terminal via a network and stores and manages the various electronic information created by the client terminal. In the management system, the client terminal operates the terminal and remotely operates the server device via a network, and transmits electronic information created by the terminal to the server device. Transmitting means for transmitting a signal to the server device, and the client terminal is configured to associate the transmitted electronic information with a predetermined management attribute value in a work area included in the server device. The server device stores a storage area for storing electronic information transmitted from the client terminal. Storage means having information, information extraction means for extracting predetermined electronic information from electronic information stored in a storage area of the storage means based on a command signal from the client terminal, and transmitted from the client terminal A work area for processing the electronic information or the electronic information extracted by the extraction means based on a command signal from the client terminal, and for trial production including the necessity for content revision of the electronic information in the work area Prototype work area that handles electronic information and electronic information for formal confirmation that does not require revision of the electronic information in the work area, or electronic information for formal confirmation that includes the necessity for revision of the contents Read the attribute value of the formal work area and the information read to the work area by the information extraction means, and according to the attribute value, the prototype work area And a distribution transfer means for distributing and transferring electronic information to one of the formal work areas, and for identifying that the electronic information distributed to the trial work area by the distribution transfer means is electronic information for prototyping An identifier setting means for setting an identifier, and determining whether an identifier is set in the electronic information in the process of storing the electronic information after being handled in both work areas in the storage area of the storage means; As a result of the determination, if the electronic information has an identifier set, the image information indicating that it is for prototyping is synthesized with the output image of the electronic information, and if the electronic information has no identifier set, the confirmation is made. Image synthesizing means for synthesizing the verified image information shown in the output image with the output image, the electronic information with the identifier set together with the identifier and the image information, and the electronic information without the identifier together with the image information. In addition, each of the storage means is configured to be re-stored in the storage area.

  [Operation / Effect] According to this configuration, the electronic information created by the client terminal and transmitted by the transmission means, or the electronic information created by the client terminal and stored in the server device is read into the work area. When the electronic information is for confirmation that does not need to be revised or includes the necessity for revision and the content is confirmed by the revision, the electronic information is put into the formal work area. The image information that has been transferred and verified is synthesized. Conversely, when the electronic information needs to be revised, the electronic information is transferred to the prototype work area and an identifier indicating the prototype is set. Based on this identifier, image information indicating that the electronic information is for trial use is displayed. Synthesized into electronic information. That is, since each piece of electronic information is synthesized with different image information in different regions, it can be easily identified whether the electronic information is prototype electronic information or confirmed formal electronic information.

  According to a second invention, in the first invention, based on the command signal of the client terminal, electronic information obtained by combining the identifier stored in the storage means and the image information for trial production is read into the work area and reprocessed. In this case, when the electronic information after the setting of the identifier is canceled and the electronic information is processed in the formal work area is stored again in the storage area of the storage means, the registration number included in the attribute value is updated. It is characterized by comprising.

  [Operation / Effect] According to this configuration, when registering formal electronic information in which the prototype electronic information is confirmed, the identifier included in the prototype electronic information read from the storage area of the storage means to the formal work area Is released. In other words, by simply synthesizing the verified image information with the prototype electronic information in the formal work area, the prototype image information can be removed and re-registered as formal electronic information. Therefore, it is not necessary to store both the prototype and formal electronic information having exactly the same contents in the storage area. As a result, an operator who browses through the client terminal can eliminate the troublesome work of discriminating both data and can suppress an unnecessary increase in capacity due to duplicate data.

  According to a third invention, in the first or second invention, the electronic information is configured by associating a design drawing of a plurality of parts constituting the product with document information, and the information is determined according to a predetermined rule. When a design drawing of a predetermined part is revised, the registration numbers and symbols of the design drawings of all the parts registered in the tree before the registered position of the part are updated to the latest one. It is characterized by comprising.

  [Action / Effect] According to this configuration, when the design drawing of a predetermined part of the tree configuration is revised, the registration numbers and symbols of all parts registered in the tree before the design drawing are updated. Management of registered drawings becomes easy.

  According to the information management system of the present invention, electronic information created by the client terminal is combined with different image information depending on the region to be processed. In particular, in the case of electronic information for prototyping, an identifier is set, and an image indicating the content of the prototyping is synthesized based on this identifier. It can be easily identified whether it is electronic information for use.

  Embodiments of the present invention will be described below with reference to the drawings. In the present embodiment, in the design of product development, a case where a product design drawing is created by CAD software and managed using a PDM system will be described as an example.

  FIG. 1 is a diagram showing a schematic configuration of an information management system according to an embodiment of the present invention.

  The information management system is configured by connecting a plurality of client terminals 1 to a server device 2 via a network such as the Internet or an intranet.

  The client terminal 1 is composed of, for example, a personal computer, and corresponds to an operation unit of the present invention. An input device such as a keyboard and a mouse, an arithmetic device, an output device such as a monitor (not shown), a storage device 3, and The communication device 4 is provided as hardware.

  This client terminal operates an input device and creates detailed document data related to drawing data in the work area of the PDM server 8 via the Internet. For example, as shown in the component configuration information screen of FIG. 2, the “P” item and the “D” drawing are displayed in the left half of the figure, and the configuration expanded from the parent item as the starting point is the configuration tree information. Is displayed. That is, information for each part including a part code, a revision symbol, a part name, a unit, and a revision constituting the product is created as configuration tree information by the client terminal.

  In the right half of the figure, there are multiple items such as “Master”, “Classification”, “Common Property”, “Individual Property”, “Related Information”, etc. The information registration screen is superimposed. For example, in FIG. 2, the “master” screen is in an active state, and detailed information on the “acrylic lid” of the component displayed on the left half is shown.

  The storage device 3 is installed with CAD (computer aided design) software 5 which is a part design support program. That is, the worker is configured to perform two-dimensional or three-dimensional modeling or design using the installed CAD software. The storage device 3 corresponds to the storage means of the present invention.

  The communication device 4 includes an information transmission module 6. This information transmission module 6 links CAD software to a PDM server 8 described later. That is, the drawing data of the parts designed by the CAD software 5 is transmitted to the server device 2. The communication device 4 corresponds to the transmission unit of the present invention.

  The server device 2 includes a database 7 and a PDM server 8 in which software for PDM (Product Data Management), which is a program that functions as an information management system, is installed.

  The database 7 is a tree structure that shows the specific form of the hierarchical structure of the data that is transmitted from each client terminal 1 and that associates the drawing data and the document data with each data of the parts that make up the product. And stored as configuration tree information.

  In the configuration tree information, for example, in the left half of FIG. 2, a part code constituting the product and information for each part corresponding to the part name, unit, and revision are created in a tree format.

  Also, drawing information for managing drawing of items is stored. As shown in FIG. 3, this drawing information shows a drawing “D” in the left half of the drawing, and displays a part code, a revision symbol, a part name, a unit, and a revision for each item. In the right half of the figure, a plurality of information registration screens such as “master”, “classification”, “common property”, “individual property”, and “related information” are superimposed. In FIG. 3, the drawing information “master” screen is in an active state, and the registration of the detailed information of the components displayed in the left half is shown in the right half screen. In addition, in the detailed information, a column “Prototype / Estimation Flag” is provided that enables confirmation of the contents of whether or not the registered drawing data is for prototyping. In other words, the ON / OFF state of the column P is confirmed, and for example, if it is “ON”, it is configured that the registered drawing data is for prototyping. The database 7 corresponds to the storage means of the present invention.

  The PDM server 8 writes and reads data to and from the database 7, and includes a plurality of work areas 9, a distribution transfer unit 10, an identifier setting unit 11, and an image composition unit 14 that process the read data. I have. The PDM server 8 has the function of the information extraction unit of the present invention, the distribution transfer unit 10 is the distribution transfer unit of the present invention, the identifier setting unit 11 is the identifier setting unit, and the image composition unit 14 is the image. Each corresponds to a combining means.

  The work area 9 is an area used as a work space for operating the data read from the database 7 and each client terminal 1 and accessing the data through the Internet to perform work such as data browsing and processing. The work area 9 is not permanently installed, and is created in a timely manner, such as when the client terminal 1 is operated to create data or when data is read from the database 7. In this work area 9, for example, CAD files such as XVL format, PDF format, and TIFF format are stored so that other workers cannot process the drawing data transmitted from the client terminal 1. Convert to any image format file.

  In addition to the work area 9, the PDM server 8 has a formal work area 12 and a prototype work area 13. The formal work area 12 is an area for handling, among the designed drawing data, drawing data in which the final specification of the product is determined. Drawing data is transferred to the formal work area 12 from the distribution transfer unit 10 described later. Then, in the formal work area 12, an administrator such as a supervisor of the worker operates the client terminal 1 and synthesizes an electronic mark created with an image indicating verification or approval at a predetermined location of the drawing data via the network. Let

  The prototype work area 13 is an area where the drawing data read out to the work area 9 is handled as the prototype drawing data. Drawing data is transferred to the prototype work area 13 from the distribution transfer unit 10 described later. In the prototype work area 13, the administrator operates the client terminal 1, and an electronic mark indicating verification or approval is combined with the drawing data, and “prototype” indicating that the drawing is prototype data. An electronic stamp whose character is an image is automatically combined at a predetermined location. The synthesis of this electronic stamp will be described later.

  The work area 9, the formal work area 12, and the prototype work area 13 are workspaces that are created in a timely manner when browsing or processing data. Therefore, after the work is completed, the data is transferred to the storage area, and at the same time, these areas are automatically deleted.

  The distribution transfer unit 10 distributes the drawing data read to the work area 9 to either the formal work area 12 or the prototype work area 13 according to a command signal from the client terminal 1 and transfers the drawing data.

  The identifier setting unit 11 automatically sets a flag as an identifier to “ON” for the drawing data determined to be transferred to the prototype work area 13 by the distribution transfer unit 10. That is, as shown in FIG. 3, the column of “prototype / estimation flag” of document data associated with drawing data to be processed such as browsing is set to “ON”. The automatic setting of the flag refers to the address of the transfer destination work area 9. For example, if the transfer destination address is “0002” when the prototype work area 13 is set, the flag is set to “ON”. In this embodiment, the address of the work area 9 is set to “0000” and the address of the formal work area 12 is set to “0001”.

  The image synthesizing unit 14 synthesizes an administrator's electronic seal created in advance with an image image or an image image of a “prototype” character at a predetermined location of drawing data.

  Next, the operation of the management system of the above embodiment will be described with reference to the flowchart shown in FIG.

  First, the operator operates the client terminal 1 to set the creation area 9 in the PDM server 8 provided in the server device 2. The operator operates the client terminal 1 and registers drawing data and parts items in the work area 9. Also, an attribute value for associating the registered drawing data with the component item is set and input. When these setting registrations are completed, drawing data of parts constituting a predetermined product created by the operator using the CAD software 5 of the client terminal 1 is transferred to the server device 2 and the PDM server 8 provided in the server device 8 is provided. Are taken into the work area 9.

  This drawing data is converted in the work area 9 into a PDF format for a two-dimensional image, a TIFF format, or an XVL format for a three-dimensional image. Then, the drawing data is associated with the attribute value of the component item set and input in advance (step S1).

  Next, it is determined whether the registered data is new or updated for trial data (step S2). If it is new, the process proceeds to step S3. If it is an update, the process proceeds to step S7.

  If it is new, the operator determines whether the created data is in the design or prototyping stage or in the stage where the product specifications are finalized (step S3).

  When it is necessary to finalize the product specifications without registering the new data, and formally register the data, the operator operates the client terminal 1 to convert the data in the work area 9 into configuration tree information. organize. If the data registered at this time is for trial production, it is only necessary to associate the attribute values between the individual part items constituting the product and the drawing data without creating the configuration tree. Thereafter, the worker operates the client terminal 1 to transmit a transfer command to the distribution transfer unit 10 of the server device 2. The distribution transfer unit 10 transfers the configuration tree information to the formal work area 12. At this time, since the transfer destination address of the configuration tree information included in the transfer signal is “0001”, the flag of the attribute value included in the data is canceled and becomes “OFF” (step S4).

  The flag state of the configuration tree information transferred to the formal work area 12 is referred to by the image composition unit 14. At this time, if the image composition unit 14 confirms that the flag is “OFF”, the electronic mark for verification or approval is permitted to be synthesized in the specific field. The administrator operates the client terminal 1 and confirms the contents of the configuration tree information in the formal work area 12. As a result of the confirmation, if the administrator determines that the content does not need to be changed, the administrator operates the client terminal 1 to transmit a command signal for synthesizing the electronic seal to a predetermined location of the drawing data and transmits it to the server device 2. . In accordance with the command signal from the client terminal 1, the image synthesizing unit 14 of the server device 2 displays the electronic seal in the “data check 17” and “approval 18” fields of the drawing data shown in FIG. Are synthesized (step S5).

  When the composition of the electronic stamp is completed, the configuration tree information in the formal work area 12 is transferred to the storage area of the database 7 and registered (step S6). The process in the case where the newly registered drawing data is handled as an official product with a final product specification is completed.

  Next, when handling newly registered data as a prototype, the process proceeds to step S7. The operator operates the client terminal 1 to transmit a transfer command to the distribution transfer unit 10 of the server device 2. The distribution transfer unit 10 transfers the configuration tree information to the prototype work area 13. At this time, the transfer destination address of the configuration tree information is “0002”. Therefore, the identifier setting unit 11 sets the flag to “ON”.

  When the configuration tree information with the flag “ON” is transferred to the prototype work area 13, the image composition unit 14 refers to the flag state. At this time, when it is confirmed that the flag is “ON”, the image composition unit 14 specifies the image image of the “prototype” character indicating that the flag is for trial use, and specifies the output drawing image 15 shown in FIG. It synthesize | combines to the location 16 (step S8).

  When the administrator determines that the content does not need to be changed, the administrator operates the client terminal 1 to generate a command signal for synthesizing the electronic mark in the specific fields 17 and 18 of the drawing data in the image synthesis in the PDM server 8. Transmitted by the unit 14. The image synthesis unit 14 synthesizes the electronic stamp into the drawing data identification fields 17 and 18 in accordance with the command signal from the client terminal 1 (step S5).

  When the synthesis of the electronic stamp is completed, the configuration tree information in the prototype work area 13 is transferred to the storage area of the database 7 and registered. At this time, the flag remains “ON”. Thereafter, the process returns to step S1 in a timely manner. This completes the processing for handling newly registered data as a prototype.

  Next, in step S2, it is determined that an old version of the processing target drawing data is registered in the storage area. In this case, in step S2, the operator operates the client terminal 1, sets the work area 9, selects an old version of the target drawing data from the storage area, and reads it into the work area 9 (hereinafter referred to as “ Called checkout). At this time, an image such as a PDF format which is drawing data checked out in the work area 9 is deleted. Therefore, the drawing data newly created by CAD is transferred from the client terminal 1 to the work area 9, and file conversion is performed. However, the checked-out old version drawing data remains in the storage area for history management.

  The worker confirms the state of the flag that is the attribute value of the drawing data checked out to the work area 9 (step S9). At this time, if the flag is "ON", the process proceeds to step S10. If the flag is “OFF”, the process proceeds to step S13.

  In step S10, the operator determines whether a new version of the drawing data in the work area 9 has been finalized in product specifications, or whether the version has been moved up and re-registered for trial use. If it is determined that the drawing data is to be handled as a prototype, the process proceeds to step S11.

  The operator operates the client terminal 1 to transmit a transfer command to the distribution transfer unit 10 of the server device 2. The distribution transfer unit 10 transfers the configuration tree information to the prototype work area 13 according to the transfer destination address. At this time, the transfer destination address of the configuration tree information is “0002”. Therefore, the identifier setting unit 11 sets the flag to “ON”. (Step S11). At substantially the same time, the revision number, which is one of the attribute values of the target drawing data, is incremented, and the revision symbol is also updated (step S12).

  In the drawing data transferred to the prototype work area 13, the image composition unit 14 synthesizes an image image of the character “prototype” into the specific portion 16 (step S8).

  Thereafter, when the administrator determines that the content does not need to be changed, the image composition unit 14 synthesizes a verification / approval electronic mark with the drawing data in accordance with a command signal from the administrator (step S8). ). Thereafter, the drawing data is transferred and registered in the storage area (step S6). At this time, the flag remains “ON”. This completes the process for re-registering the updated drawing data for prototyping.

  Next, when the worker determines in step S10 that the product specification has been confirmed for the new version of the drawing data whose contents are changed in the work area 9, the process proceeds to step S13. In step S13, the operator changes the contents of the drawing data checked out from the storage area and updates it to a new version, or keeps the contents of the current version and saves the storage area as drawing data with the final product specifications. Judge whether to register with.

  If there is a change in the contents of the drawing data, the flag of the drawing data in the work area 9 is set to “OFF” (step S14), and at the same time, the revision number is incremented and the revision symbol is also updated (step S15). . Here, the processes of steps S14 and S15 are the same as the processes of steps S4 and S12 described above.

  The drawing data with the updated attribute value such as the revision is transferred to the formal business area 12. If the administrator determines that the content does not need to be changed, the administrator transmits a command signal for synthesizing the verification / approval electronic stamp to the server device 2. The image composition unit 14 of the server device 2 composes the electronic mark into the drawing data specifying fields 17 and 18 in accordance with the command signal (step S5). The drawing data is transferred and registered in the storage area (step S6). This completes the process for updating the contents of the drawing data after check-out and registering it in the storage area as official drawing data.

  Next, a case will be described in which, in step S13, the operator registers in the storage area as drawing data in which the product specifications are confirmed while maintaining the current version contents of the drawing data checked out from the storage area.

  In this case, the current version used for prototyping is formally registered as drawing data with a final product specification, so the flag is set to “OFF”. At the same time, the image composition unit 14 deletes the image image of the character “prototype” indicating that it is for trial use. Then, the drawing data from which the characters “prototype” are deleted is transferred to the formal work area 12 while maintaining the current revision (step S16).

  Thereafter, when the administrator determines that the content does not need to be changed, the administrator transmits a command signal for synthesizing the verification / approval electronic seal to the server device 2. The image composition unit 14 of the server device 2 composes the electronic mark into the drawing data specifying fields 17 and 18 in accordance with the command signal (step S5). The drawing data is transferred and registered in the storage area (step S6). This completes the processing for registering the checked-out drawing data as it is in the storage area as the drawing data with the final product specifications.

  Next, a case where the flag is “OFF” in step S9 will be described.

  The operator determines whether the checked-out drawing data is a product specification confirmed (step S17). Here, in the case of formal registration, the process proceeds to step S18. In the case of performing processing such as registration update for trial manufacture, the process proceeds to step S20.

  In step S18, the distribution transfer unit 11 transfers the checked-out drawing data to the formal work area 12 because the flag is “OFF”. At this time, since the drawing data is formally registered with the current version, the revision and revision symbol are updated (step S19).

  When the drawing data is transferred to the formal work area 12, the processes in steps S5 and S6 described above are performed, and the process ends.

  When the process proceeds to step S20, the drawing data registered as a formal drawing checked out from the storage area is prohibited from being transferred to the prototype work area 13 by the distribution transfer unit 10, and the process is forcibly terminated.

  As described above, every time the drawing data of the parts constituting the product is modified / changed, the latest configuration tree information is checked out to the work area 9, and after confirmation, the configuration tree information is prototyped by the operator. It is transferred to either the work area 13 or the formal work area 12. At this time, if the drawing data of the configuration tree information is for prototyping, by moving to the prototyping work area 13, an image image indicating that it is a prototyping is automatically synthesized with drawing data of the output image of the drawing data. The

  In addition, when the product specification is confirmed, the configuration tree information is transferred to the formal work area 12, whereby the image showing the prototype is deleted and can be re-registered as the final drawing data. In addition, revisions are updated with each revision / update. Therefore, an operator or administrator who browses the drawing data can easily know the change history of the registered information. It is also easy to see if it is for prototyping or official drawing data. Furthermore, it is not necessary to register the prototype data and the formal drawing data redundantly, so that the data amount can be reduced and the processing efficiency can be improved.

  The present invention is not limited to the above-described embodiment, and can be modified as follows.

  (1) In the above-described embodiment, when the drawing data at a predetermined location that is the configuration tree information is corrected or changed, the revision value of the drawing data is updated. The revisions of the drawing data may be updated at the same time, or the revisions of multiple part drawing data registered in the tree before the correction / change target drawing data may be updated to match the same revision. Good. When updating revisions in part, it was easy to know which components were modified or changed.

  (2) In the above-described embodiment, the case where the drawing data is managed has been described as an example. However, the management system can also be applied to the case where data that requires correction / change such as a plan document is managed.

It is a figure which shows the structure of the information management system which concerns on an Example. It is a figure which shows the output screen of the data for registration. It is a figure which shows the output screen of the registered data. It is a flowchart which shows the process of the information management system of a present Example.
