Description

  The present invention relates to a design drawing management system for managing design drawings of parts constituting a product.

  Conventionally, design drawings of parts constituting a product are often created using CAD (Computer-Aided Design), and are usually stored and managed as an electronic CAD file. When such a management system creates a CAD file, design information such as a product number is described as a search keyword in the title column of the CAD file. As a result, the design drawing can be searched for a desired CAD file based on the design information extracted as the search keyword.

In such a management system, a CAD file is a general purpose such as a TIFF (Tag Image File Format) file in order to easily display the contents of the CAD file on a terminal of a designer who is searching for the CAD file. A technique for converting the file into a format file has also been proposed (see, for example, Patent Document 1).
JP 2002-358336 A

  However, in the conventional management system including the above-described Patent Document 1, the conversion accuracy of design information described as character data on the CAD file is increased as the CAD file is converted into a file of another format. In some cases, the design information may not be displayed on the designer's terminal because there may be a problem such as a drop or lack of design information.

  Further, in a conventional management system, when a CAD file is searched without being converted into a file of another format, the number of CAD files to be searched becomes enormous, so that batch processing cannot be performed. . For this reason, it may be possible to separately perform processing such as grouping and aggregation, but such processing has not been able to efficiently display effective design information on the designer's terminal. .

  Therefore, the present invention has been devised to solve the above-described problems, and the designer can consider the product and the component configuration without converting the CAD file into a file of another format. It is an object of the present invention to provide a design drawing management system capable of reliably providing valid design information to be confirmed in a format easy to view.

  A design drawing management system according to the present invention manages a design drawing of a part constituting a product and electronically stores a design drawing of each part in which annotation information is described as character data A configuration information storage unit that stores configuration information indicating a parent-child relationship between products and parts, a search information generation unit that generates search information related to a design drawing, and a design information database based on an input search keyword A search processing unit for searching for a design drawing, and an output unit for outputting a search result by the search processing unit.

  In such a design drawing management system, as search pre-processing, the search information generation unit extracts the note information described in the design drawing stored in the design drawing database and stores it in the configuration information storage unit. For each part, the number of products in which each part is used is calculated, and search information related to each design drawing is generated based on the extracted note information and the calculated number of products. Keep it. The design drawing management system according to the present invention searches the design drawing based on the search keyword with respect to the search information generated by the search information generation unit by the search processing unit in order to solve the above-described problem, The search results are rearranged so that the design drawings of the parts including the annotation information included in the searched design drawings and having a large number of products are displayed at the top, and are output via the output unit.

  According to the design drawing management system according to the present invention, it is easy to view effective note information to be confirmed by a designer in consideration of products and component configurations without converting the design drawing file into a file of another format. It can be surely provided in the form, and it is possible to check the note information to be confirmed by the designer without omission.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[Configuration of design drawing management system]
As shown in FIG. 1, a design drawing management system to which the present invention is applied includes a design drawing database 11 that electronically stores design drawings of parts that constitute a product, and configuration information that indicates a parent-child relationship between the product and the parts. A configuration information storage unit 12 to store, a search information generation unit 13 to generate search information related to the design drawing, a search information storage unit 14 to store the search information generated by the search information generation unit 13, and a search keyword Is input, a search processing unit 16 that performs a search based on a search keyword, and an output unit 17 that outputs a search result by the search processing unit 16.

  The design drawing database 11 stores design drawings of parts constituting a product as a file in a predetermined format such as CAD (Computer-Aided Design). The design drawing file includes the design drawing data in which notation information such as design information such as a product number and additional information that prompts the designer to call is described. The design drawing file stored in the design drawing database 11 is read by the search information generating unit 13.

  The configuration information storage unit 12 stores product or component configuration information IM1 input separately, that is, configuration information indicating a parent-child relationship of each component. The product and component configuration information IM1 is information that lists which components are used to configure the product for each product, for example in a tree shape. The configuration information storage unit 12 stores such product or component configuration information IM1 as a database. The configuration information stored in the configuration information storage unit 12 is read by the search information generation unit 13.

  The search information generation unit 13 reads a design drawing file stored in the design drawing database 11 and extracts annotation information described as characters in the design drawing file. Further, the search information generation unit 13 calculates the number of products in which each part is used for each part based on the configuration information stored in the configuration information storage unit 12.

  Specifically, the search information generation unit 13 reads the configuration information stored in the configuration information storage unit 12 and converts it into component-based configuration information, thereby calculating the number of products in which each component is used. . In other words, the search information generation unit 13 converts the product-based configuration information describing the components that make up the product for each product into the component-based configuration information describing the products for which the component is used for each component. . For example, as illustrated in FIG. 2, the search information generation unit 13 uses the configuration information read from the configuration information storage 12 to the product A configured using the two components a and b, and the two components a and c. If the product B configured using the product is included, the part standard used for the two products A and B, the part b used for the one product A, etc. Convert to configuration information. Note that the search information generation unit 13 also converts to component information based on child components in the same manner even when the component is composed of a plurality of child components. When the number of products used for each part is calculated by performing such conversion processing, the search information generation unit 13 generates search information including the extracted note information, the calculated number of products, and the design drawing. It is stored in the search information storage unit 14.

  The search information storage unit 14 includes, for example, a memory and stores the search information generated by the search information generation unit 13. The search information stored in the search information storage unit 14 is read by the search processing unit 16.

  The input unit 15 receives a search keyword input by operating its own terminal when the designer makes a search request. The input unit 15 supplies the input search keyword to the search processing unit 16.

  The search processing unit 16 searches the design drawing file based on the search keyword input from the input unit 15. At this time, the search processing unit 16 gives a score to each searched design drawing file based on the search information stored in the search information storage unit 14. Specifically, the search processing unit 16 converts the searched design drawing file into a design drawing file for a part having a large number of products in use or a design drawing file for a part including note information. Give a high score. Then, the search processing unit 16 sorts the search results so that the design drawing file for the part with a high score is displayed at the top, and the search display so that the design drawing file for the part with a high score is displayed first. Information IM2 is created.

  The grade given to the design drawing file does not matter if the important design drawing file including annotation information and having a large number of products is displayed at the top in the search result.

  For example, as shown in FIG. 3, when the designer inputs a search keyword α and makes a search request, the search processing unit 16 searches for a design drawing file for a part including the search keyword α as annotation information. Assume that design drawing files for three parts a, b, and c are retrieved. At this time, the search processing unit 16 gives a high score to the design drawing file for the part a having the largest number of products in use among the searched parts a, b, and c, and the design drawing for the part a. The search display information IM2 is created so that the file is displayed in the upper (1). The design drawing files for the products b and c are displayed in (2) and (3) below the part a. The search processing unit 16 supplies the search display information IM2 created in this way to the output unit 17.

  The output unit 17 outputs the search display information IM2 so that the search display information IM2 created by the search processing unit 16 is displayed on the designer's terminal.

[Operation of design drawing management system]
When such a design management system receives a search keyword input by the designer operating his / her terminal through the input unit 15, the search processing unit 16 searches the design drawing file based on the search keyword. Do. At this time, the search information generation unit 13 generates search information by performing a series of processes as shown in FIG. 4 in order to create the search display information IM2 by the search processing unit 16.

  First, in step S1, the search information generation unit 13 reads the configuration information stored in the configuration information storage unit 12 and converts it into component-based configuration information. In step S2, the search information generation unit 13 acquires the number of design drawing files to be searched from the design drawing database 11. In step S3, the search information generation unit 13 acquires one design drawing file to be searched from the design drawing database 11. read out.

  Subsequently, in step S4, the search information generation unit 13 extracts the note information described in the design drawing file read out in step S3. In step S5, the search information generation unit 13 converts the component reference generated in step S1. Based on the configuration information and the annotation information extracted in step S4, search information related to the design drawing file is generated and stored in the search information storage unit.

  In step S6, the search information generation unit 13 determines whether or not there remains a design drawing file for which search information is to be generated. That is, the search information generation unit 13 performs steps S3 to S5 in the design drawing file to be searched. It is determined whether there is a design drawing file that has not been performed. When there is still a design drawing file for which search information is to be generated, the search information generation unit 13 repeats the process from step S3, performs the process for all design drawing files to be searched, and searches the search information. When is generated, a series of processing is terminated.

  The design drawing management system performs such a series of processes by the search information generation unit 13 so that the design drawing file searched based on the search keyword input by the designer has a large number of products in use. The design drawing file for the part including the annotation information, that is, the design drawing file for the part with high importance to be confirmed by the designer can be rearranged so as to be displayed at the top.

  In the design drawing management system, when the search information is generated by the search information generation unit 13, the search information is not generated based on only information on whether or not the design drawing file includes annotation information. When the search display information IM2 is generated by the search processing unit 16 by weighting when the note information is included, a score corresponding to the weight is given, and the search result with a finer ranking is displayed. It can be presented.

  Specifically, the search information generation unit 13 can generate search information by performing weighting according to the position where the note information is described in the design drawing file. Then, the search processing unit 16 gives a high score to the design drawing file for the part in which the annotation information is described at the position where the importance level is high, and among the searched design drawing files, the design drawing file with the high score is the higher rank. The search display information IM2 as displayed on the screen is created.

  For example, as shown in FIG. 5, the search information generation unit 13 sets a region in the design drawing 100 having a plurality of important levels 1 to 3 such that a conspicuous region in the design drawing 100 is a region having a high importance level. When the note information is described in the areas 101 to 103 and the area having a high importance level is described, the note information is weighted. Then, for example, as illustrated in FIG. 6, the search processing unit 16 has searched the design drawing files for the three parts a, b, and c as the design drawing files for the parts including the search keyword α as the annotation information. In such a case, a high score is given to the design drawing file for the part a in which the annotation information is described in the area having a high importance level, and the design drawing file for the part a is displayed in the upper (1). Display information IM2 is created.

  As a result, in the design drawing management system, it is possible to perform a search that notes information is described in a prominent position in the design drawing file, etc., when the importance of the designer to be confirmed is high. The search result with a finer ranking can be presented.

  Further, in the design drawing management system, for example, an important word / phrase used as note information such as the word / phrase “important!” Is defined in advance, and the search information generating unit 13 includes the important word / phrase when the search information is generated. The note information may be weighted. Thereby, when the search display information IM2 is created by the search processing unit 16, a score corresponding to the weight can be given.

  Specifically, the search information generation unit 13 refers to an unillustrated important phrase storage unit that stores important phrases used as note information, and is stored in the important phrase storage unit, for example, as shown in FIG. When the note information 110 including an important phrase is described in the design drawing 100, the note information 110 is weighted. Then, for example, as shown in FIG. 8, the search processing unit 16 searches the design drawing files for the three parts a, b, and c as the design drawing files for the parts including the search keyword α as the annotation information. In such a case, the search display information IM2 is such that a high score is given to the design drawing file for the part a in which the note information including the important words is described, and the design drawing file for the part a is displayed at the top. Create

  As a result, in the design drawing management system, it is possible for the designer to perform the design work without overlooking the note information that prompts “important!” Or the like.
