Description
- 1. Field of the Invention
- The present invention relates to a CAD management system and a CAD information management method, and more particularly, to a CAD management system and a CAD information management method which are suitable to manage CAD drawing information.
- 2. Description of the Related Art
- A computer forms a drawing to design various pieces of equipment. As disclosed in Japanese Unexamined Patent Application Publication No. 9-91327 and in Japanese Unexamined Patent Application Publication No. 9-62728, in the case of managing CAD (Computer Aided Design) drawing information which is formed by a computer, CAD drawings such as P&ID (Piping and Instrumentation Diagram) are used by one plant manufacturer or by one information management company. The CAD drawings do not consider a case in which an order company of a power generation plant or the plant manager uses a database under the plant manufacturer or the information manager.
- Conventionally, a company which forms the CAD drawing stores CAD drawing information in its own database and the plant manufacturer or information manager which forms the CAD drawing information uses the individual database. Therefore, when the order company of the power generation plant or the plant manager uses the database which the plant manufacturer or the information manager has, information on the CAD drawing and an equipment specification is temporarily extracted from the database which the power generation plant manufacturer or the information manager has, the extracted information is fetched to the database which is managed by the order company of the plant or the plant manager. Consequently, new information such as progressing status of a periodical check or replacement of equipment is recorded to the database which the order company of the plant or the plant manger has, different from the database which the plant manufacturer or the information manager has, and is managed by the order company of the plant or the plant manger.
- According to the above conventional arts, when the order company of the plant or the plant manager uses the CAD drawing or the equipment specification information which a plurality of plant manufacturers or a plurality of information managers have, the database which the plant manufacturer has cannot be directly accessed. A database, different from that of the plant manufacturer, must be additionally provided. Consequently, it is troublesome that the order company of the plant or the like constructs a specific database. Further there is a problem in that since the order company of the plant and the plant manufacturer update information stored in the database in different manners, a difference is caused between the databases formed by the order company of the plant and the plant manufacturer. The information management by the order company of the plant becomes difficult. In particular, when a plurality of plant manufacturers manage information, even in the case of the same product, a difference between update information is caused.

That is, theinformation determining unit 49 determines whether or not the update content corresponds to the content of the information used by a specific user, e.g., information of the periodical check and, alternatively, whether or not the update content corresponds to the content shared by the manufacturers, e.g., the CAD drawing or the equipment specification. - In
step 108, when theinformation determining unit 49 determines that the update content corresponds to the content of the information used by the specific user, theinformation determining unit 49 accesses one of thedatabases information registering unit 43, and directly overwrites and corrects the dada which is stored in the corresponding database. Simultaneously, theinformation determining unit 49 updates the update history of the CAD drawing or the equipment specification, which is stored in the corresponding database, and displays the end of the update on the screen of the display 46 (step 109A). - In
step 108, when theinformation determining unit 49 determines that the update content corresponds to the content shared by the manufacturers, first, theinformation determining unit 49 requests the update of the information to the manufacturer and requests the manufacturer for the acceptance of the update (step 109B). If the manufacturer accepts the update of the information, an information management apparatus (information management means) of the manufacturer transfers the notification of the acceptance of the update of the information to theuser terminal 40. When the manufacturer inputs the notification of the acceptance of the update of the information to theuser terminal 40, theinformation determining unit 49 accesses one of thedatabases information registering unit 43, and directly overwrites and corrects the data which is stored in the corresponding database. Simultaneously, theinformation determining unit 49 updates the update history of the CAD drawing or the equipment specification which is stored in the corresponding database, and displays the end of the update on the screen of the display 46 (step 109C). - In
step 108, When theinformation determining unit 49 determines that the manufacturer dose not accept the update, the manufacturer transfers the notification indicating that the update is not accepted, to theuser terminal 40. In this case, theinformation determining unit 49 displays a fact indicating that the update is not accepted, on the screen of the display 46 (step 111), and the process in this routine ends. - According to the first embodiment, even if the databases which different manufacturers have are distributionally provided, the CAD drawing information or the equipment specification information can be easily browsed by searching for the information from the
user terminal 40 in accordance with the data stored-destination address information. The user can update the information within the acceptable content. Further, since the update history is displayed, the user can easily understand the update date, etc. - Hereinbelow, A description is given of a second embodiment of the present invention with reference to FIG. 5.

Further, thesearch unit 48 determines whether or not there is the update history of the CAD drawing. If it is determined that there is the update history of the CAD drawing, thesearch unit 48 displays the update history on the screen of thedisplay 46. If it is determined instep 202 that there is no corresponding information on the CAD drawing or the equipment specification, theserver 70 transfers such a fact to theuser terminal 40, and the processing routine returns to step 101 (step 203B). - Next, when the information from one of the
databases user terminal 40 via theserver 70 and the content thereof is displayed on the screen of thedisplay 46, the user can freely browse the information on the CAD drawing or the equipment specification, which is displayed on the screen of the display 46 (step 106). - In this case, since the user desirably operates the CAD information management system, the CAD information management system is in the standby mode. The user can use various tools for browsing.
- If the user performs an operation for browsing the information on the equipment specification which is displayed on the CAD drawing, processing for searching for the information on the equipment specification is instructed, thereby starting the process in
step 201. - If the user desires to correct or update the information on the CAD drawing or the equipment specification because of the change of the CAD information management system, the user can update the information on the screen of the display46 (step 107).
- When the user updates the information in
step 107, thesearch unit 48 transfers the request for updating the information and the update content (step 204). In this case, thesearch unit 48 extracts the stored-destination address information, of the CAD drawing or the equipment specification which is requested to be updated, from theinformation registering unit 43 and transfers the extracted information to theserver 70. - When the update is requested, the
server 70 determines whether or not the update content is correct (step 205). For example, theserver 70 determines whether or not the update content, e.g., the information on the periodic check corresponds to the content used by a specific user and, alternatively, whether or not the information on the CAD drawing or the equipment specification corresponds to the content shared by the manufacturer (step 205). In this case, if it is determined that the update content corresponds to the content used by the specific user, theserver 70 accesses one of thedatabases user terminal 40, and directly overwrites and corrects the data of one of thedatabases step 206A). In this case, the update history of the CAD drawing or the equipment specification, which is stored in one of thedatabases 10 to 21, is updated and the end of the update is transferred to theuser terminal 40. - When the notification of the update is received from the
server 70, theuser 40 displays the end of the update on the screen of the display 46 (step 207). - When the
server 70 determines instep 205 that the update content corresponds to the content shared by the manufacturer, theserver 70 requests the update of the information to the manufacturer and also requests the determination of the update thereto (step 206B). - When the manufacturer accepts the update of the information, the information management apparatus of the manufacturer transfers the notification indicating that the update of the information is accepted to the server70 (
step 208A). - When the
server 70 determines instep 205 that the update content corresponds to the content used by the specific user, theserver 70 accesses one of thedatabases user terminal 40, and directly overwrites and corrects the data of one of thedatabases step 206A). In this case, theserver 70 updates the update history, of the information on the CAD drawing or the equipment specification which is stored in one of thedatabases 10 to 21, and transfers the end of the update to theuser terminal 40. - In the
user terminal 40, when the notification of the update is received from theserver 70, thesearch unit 48 displays the end of the update on the screen of the display 46 (step 207). - When the manufacturer does not accept the update of the information in
step 206B, the manufacturer transfers the notification indicating that the update is not accepted, to theserver 70, and theserver 70 transfers the notification indicating that the update is not accepted, to the user terminal 40 (step 209). In this case, in theuser terminal 40, thesearch unit 48 displays the notification indicating that the update is not accepted, on the screen of the display 46 (step 210), and the processing routine ends. - According to the second embodiment, even if the databases which different manufacturers have are distributionally provided, the CAD drawing information or the equipment specification information can be easily browsed by searching for the information in the databases from the
user terminal 40 in accordance with the data stored-destination address information via theserver 70. The user can update the information within the acceptable content. - Further, according to the second embodiment, differently from the case according to the first embodiment, the
server 70 shares the processes which are performed by theserver 70 and theuser terminal 40. Consequently, the processing speed can be increased. - Furthermore, according to the second embodiment, since necessary information can be selected or updated, the order company of the power generation plant or the information manager can efficiently mange the information on the CAD drawing or the equipment specification.
