The person in charge of the company A inputs the system login information (step S122) and requests the system login (step S123) by entering the user ID and the password on the login screen based on the password sent in advance.

Upon receiving the system login request, the drawing management server 40 determines the system login based on the received system login information, that is, the user ID and password (step S124). As a result of the determination, for example, if the login cannot be permitted due to an error in the input of the password and the determination is NG (step S125), the system login NG notification is sent to the user (company A) side terminal device. By transmitting to 1A, the person in charge of company A is notified that login to the system could not be made (step S126).

Therefore, the person in charge of company A re-enters correct login information again on the system login screen (step S131), operates the user (company A) side terminal device 1A again, and issues a system login request to the drawing management server 40. (Step S132). Upon receiving the system login request from the user (company A) side terminal device 1A, the drawing management server 40 makes a system login determination based on the transmitted user ID and password (step S133), and as a result of the determination, it is correct. If the determination is OK due to the transmission of the system login information (step S134), a system login completion notification is transmitted to the user (company A) side terminal device 1A, so that the person in charge of company A can be informed. Notify that the system login is completed (step S135). The person in charge of the company A who has received the system login completion notification terminates the system login screen of the user (company A) side terminal device 1A, and the system login process is completed (step S136).

Note that the login process to this system is performed in the same manner for the maker side terminal device 30, and the person in charge of the maker activates the maker side terminal device 30 and activates the system login screen to display the correct login information. After inputting (step S141), a system login request is made to the drawing management server 40 (step S142). Then, the drawing management server 40 that has received the system login request from the maker side terminal device 30 determines the system login based on the transmitted user ID and password (step S143), and as a result of the determination, correct system login is performed. If the determination is OK due to the transmission of the information (step S144), the system login completion notification is transmitted to the manufacturer side terminal device 30 to notify the person in charge of the manufacturer that the system login has been completed. Notify (step S145). The person in charge of the manufacturer who has received the system login completion notification terminates the system login screen of the manufacturer side terminal device 30 and completes the system login process (step S146).

By completing the system login process shown in FIG. 4 described above, the user (company A) side terminal device 1A and the manufacturer side terminal device 30 are permitted to log in to the drawing management server 40, and the drawing management system according to the present embodiment. The usage status of is established. The user ID and password, which are the system login information, can be arbitrarily changed from the initial settings. For example, when the user (company A) side terminal device 1A or the maker side terminal device 30 requests a password change, the drawing management server 40 that receives the request requests the new password system to be transmitted. By saving the login information in the login authority information management database 42, the system login information is updated, and in the system login processing from the next time onward, the system login processing is performed with the newest system login information after the change.

Next, the tag information setting process shown in FIG. 5 will be described. This tag information setting process is a process performed by a person in charge on the maker side using the maker side terminal device 30. Further, the tag information functions as a marker for extracting a part of the specialized character information existing in the drawing and roughly grasping what the drawing is like. It is information, and is set so that one or more pieces or a plurality of pieces are attached to a plurality of drawing data. By setting such tag information in advance, the order request processing described later can be smoothly executed. First, the person in charge of the maker activates the tag information setting screen with the maker side terminal device 30 logged in to the system (step S151), and inputs the tag information to be registered in advance on this tag information setting screen. (Step S152). Examples of the tag information input at this time are character information such as "joint tolerance special", "joint specification", "counter-standard", "axis number not defined", and "C cap". After inputting the tag information (step S152), a tag information setting request is transmitted to the drawing management server 40 (step S153). The drawing management server 40 that has received the tag information setting request (step S154) stores the received tag information in the tag information management database 43 (step S155), and sends a tag information setting completion notification to the maker side terminal device 30. Yes (step S156). In the maker side terminal device 30 that has received the tag information setting completion notification, the person in charge of the maker confirms that the tag information has been set, and by closing the tag information setting screen that was activated in the maker side terminal device 30, The tag information setting process is completed (step S157).

It should be noted that upon completion of each process described with reference to FIGS. 3 to 5, pre-setting in the drawing management system according to the present embodiment is completed, and full-scale use of the system becomes possible. Therefore, next, the ordering request process will be described with reference to FIG.

The order request processing shown in FIG. 6 is useful when a person in charge of the company A who is a user customizes a product other than a catalog product according to the specifications of the company and purchases a new product. The person in charge of the company A activates the user (company A) side terminal device 1A, performs the system login described with reference to FIG. 4, and then activates the order request screen (step S161). Then, the specification information of the product to be ordered is input to this order request screen (step S162), and the ordered product specification information is transmitted to the maker side terminal device 30 (step S163). The manufacturer's terminal device 30 that has received the order product specification information from the user (company A) side terminal device 1A acquires this ordered product specification information (step S164) and operates the manufacturer's terminal device 30. The person in charge of is able to confirm the ordered product specification information from the person in charge of Company A.

At this stage, the person in charge on the manufacturer side can scrutinize the contents of the ordered product specification information transmitted from the person in charge of the company A and organize the specification information (step S165). For example, when the person in charge of Company A sends a handwritten instruction by including it in the ordered product specification information, the handwritten instruction content is digitized in consideration of the data analysis performed by the drawing data analysis unit 55 later. Preferably. Further, as a person in charge of the manufacturer, the knowledge of the manufacturer is taken into consideration, and the ordered product specification information from the person in charge of the company A is revised as the ordered product specification information. The person in charge on the maker side transmits the order product specification information thus created from the maker side terminal device 30 to the drawing management server 40 (step S166).

When the drawing management server 40 receives the ordered product specification information transmitted from the maker side terminal device 30 (step S167), the drawing management server 40 receives the ordered product specification information, the tag information management database 43, and the user (company A). The drawing data analysis unit 55 executes processing based on the information stored in the past drawing management database 44 and the machine learning information management database 46, thereby executing drawing data analysis (step S168).

Here, the contents of the drawing data analysis shown in step S168 will be described. The drawing data analysis unit 55 executes the drawing data analysis (step S168). In response to a request from the product specification information management unit 53 that has received the specification information of the ordered product transmitted from the maker side terminal device 30, the user (Company A) By accessing the past drawing management database 44 and comparing the drawing data created in the past between Company A and the manufacturer with the specification information of the ordered product, and analyzing it, the product requested this time The process of extracting the past drawing data closest to the specification information of is performed. Various techniques can be used for this comparison analysis.

Specific contents of the drawing data analysis (step S168) executed by the drawing data analysis unit 55 include, for example, the product specification of the product ordered by the user and a plurality of drawings created in the past between the maker and the user. Compare and search the data, and extract the drawing data group related to the product specification of the product from the multiple drawing data created in the past, and rank the extracted drawing data group in descending order of the agreement rate with the product specification of the product. There is a drawing data analysis method attached.

The drawing data analysis unit executed by the drawing data analysis unit 55 performs optical character recognition (OCR) on each of a plurality of drawing data created in the past between the maker and the user to obtain character information in the drawing data. Text extraction and text analysis are performed. Further, the drawing management server 40 is made to learn the character information extracted by the text analysis executed by the drawing data analysis unit 55 by machine learning to generate a text analysis learning model, and this text analysis learning model is managed by machine learning information management. It can be stored in the database 46.

The drawing data analysis unit executed by the drawing data analysis unit 55 extracts image information from each of a plurality of drawing data created in the past between a maker and a user and executes image analysis. Be done. The image analysis performed by the drawing data analysis unit 55 is based on the degree of agreement between preset model drawing information and the image information obtained by image extraction, and the drawing type (for example, front view, side view, perspective view, etc.). Can be determined. Further, the drawing management server 40 learns the image information extracted by the image analysis performed by the drawing data analysis unit 55 by machine learning to generate an image analysis learning model, and the image analysis learning model is stored in the machine learning information management database. Can be stored at 46.

A specific example of the above-mentioned optical character recognition (OCR) and image extraction is shown in FIG. FIG. 8A (a) shows an example of a mechanical drawing for manufacturing a product provided by the manufacturer. In this type of mechanical drawing, the display name, drawing name, parts list, etc. are shown in the lower right. Further, in the figure, there is a diagram as a collection of lines and a character string indicating the contents of the annotation. In the drawing management system according to the present embodiment, the drawing data analysis unit 55 of the drawing management server 40 uses the drawing rule of the mechanical drawing as described above to perform drawing processing when performing optical character recognition (OCR) or image extraction. It is configured to preset which area in the optical character recognition (OCR) and which area should be image-extracted. Specifically, as shown in the diagram (b) in FIG. 8, the display of the drawing name, the drawing name, the parts list, etc. is basically arranged at the lower right of the drawing data. By performing optical character recognition (OCR) with the area shown by as the area where the name of the drawing, the name of the drawing, the parts list, etc. are displayed, the text information in the drawing data can be extracted and text analysis can be performed. Done. Further, when there is a collection of characters which is not a line drawing in the drawing, the drawing data analysis unit 55 recognizes that a character string indicating the contents of the note exists at this location, and the area indicated by the reference symbol α2 By performing optical character recognition (OCR), the character information in the drawing data is extracted as text, and text analysis is performed. Further, for a line diagram that can be grasped as a set of lines, an image extraction area is set for each line diagram as indicated by reference signs β1 to β4, image information is extracted from each line image, and image analysis is performed. Is done. By using the “text analysis learning model” and the “image analysis learning model” stored in the machine learning information management database 46, the drawing data analysis unit 55 extracts an image in each area indicated by reference signs β1 to β4. Based on the image information obtained, the image analysis is performed after recognizing what format the extracted image information shows, for example, a front view, a side view, or a perspective view. It is possible to execute.

Further, the drawing data analysis unit 55 extracts the tag information preset and stored in the tag information management database 43, and also performs text extraction by performing the optical character recognition (OCR) with this tag information. By comparing with the character information in the drawing data, if the same (or similar) character information exists, this character information is adopted as tag information, and the adopted tag information is applied to the drawing data. Can be granted. An example of adding such tag information is shown in FIG. Here, regarding the mechanical drawing of the product manufactured by the manufacturer, even if the person in charge of the manufacturer is the creator of the drawing, how the drawing was made and how it was used in past manufacturing It is very difficult to know at a glance what was used for. In particular, at the ordering stage, the person in charge of the company A, who is the user, can confirm the specifications of his or her own product, but cannot easily grasp the details of the product to be ordered. On the other hand, it is not easy for sales personnel to grasp the details of the drawings for the person in charge of the manufacturer, and even if the person in charge of development is the drawing not drawn by himself, the contents can be immediately understood. It's not easy to figure out. However, in the present embodiment, as shown in FIG. 9, the function of the drawing data analysis unit 55 adds tag information indicated by the symbol γ to the extracted drawing data. This tag information γ simply shows a characteristic keyword for manufacturing a product, and functions as a very useful marker for roughly understanding the contents of the drawing data. By using the tag information γ by the person in charge of the company A who is the user side or the person in charge of the manufacturer side, the contents of the extracted past drawings can be easily grasped, and the new ordering product When creating a drawing, it is possible to greatly improve work efficiency.

By the drawing data analysis by the drawing data analysis unit 55 described above, past drawing data is extracted as a prioritized drawing data group. In addition, the extracted drawing data are individually matched with the required specifications of the ordered products. The analysis results thus obtained are listed by the image list editing unit 56 in descending order of matching rate (step S169). Then, the drawing management server 40 transmits a drawing data listing completion notification to the maker side terminal device 30 and the user (company A) side terminal device 1A (steps S170, S171), and sends the drawing data listing completion notification. The manufacturer side terminal device 30 and the user (company A) side terminal device 1A that have received the drawing data browsing request are transmitted from the respective past drawing list acquisition units 14 and 34 (steps S172 and S173), and the drawing data browsing request is sent.
