JP 09-091327 A Japanese Patent Application Laid-Open No. 07-296065

  The problem to be solved is to browse the drawings required on the site with few operations.

  According to the present invention, when a part in a displayed drawing is selected, one of the link candidates between character strings common to a plurality of drawings is selected according to a rule in order to construct a browsing system that displays a link destination. The main feature is to generate links.

  Since the link is directly attached to the drawing that the viewer wants to see next, the viewer can quickly display the drawing that the user wants to see by specifying the ID part of the drawing.

It is a system configuration diagram. It is an example of screen operation. It is an example of screen operation. It is an example of screen operation. It is a structural example of an ID index. It is a structural example of the link information 6. FIG. It is an operation | movement flowchart of the book browsing apparatus 200. FIG. It is an operation | movement flowchart of the link production | generation part 5. FIG. It is an example of a data structure of the flow order of a reference. It is a data structural example of RFID information 11. FIG.

  If it is an image drawing, after recognizing the drawing, a character string is extracted from the drawing, and if a common character string is extracted among a plurality of drawings, a link candidate is generated between the character strings and a link is generated according to the rule. It was realized.

  FIG. 1 is a system configuration diagram of an embodiment of the apparatus of the present invention.

  The drawing browsing system includes a browsing terminal 100, a book browsing device 200, and a support device 300. The browsing terminal 100 is a function necessary for browsing a browsing terminal or the like. The browsing terminal brought to the site will function if this part is present. The browsing terminal is a portable computer or the like, and each function of the browsing unit 7 and the work mode designating unit 8 is controlled by the CPU. Information of the work mode designating unit 8 is obtained from an input / output unit connected to the reader 10. The drawing database 1 and the link information database 6 are recording devices and may be provided in the browsing terminal, or information may be obtained by communicating with the database via an input / output unit. The book browsing device 200 is a book browsing device such as a server or a computer, and is a function necessary for generating the link information 6. New drawing data may be operated at the timing when new drawing data is registered or updated in drawing data 1, or the user may drive activation. The support apparatus 300 is a support apparatus such as a computer and has a function of supporting an input device. The browsing terminal 100 operates even if it is not, but if it is present, it is easy to input the ID at the site.

  The drawing database 1 includes, as a design drawing, a cable connection diagram indicating the cable connection specifications between the devices, a cable tray showing the cable tray and the wiring of the conduit through the cable origination point, and the cable tray in the floor. Drawing data such as a tray diagram indicating the position and a conduit diagram indicating the conduit position in the floor is recorded and held. Some of these design drawings are in a form (eg, pdf) in which the device name or cable name can be searched as a character string, but some are in a form (eg: tiff) that cannot be searched as a character string as an image. The drawing recognition unit 2 recognizes the drawing in the image format and extracts a character string and a position in the drawing. The position in the drawing of the character string of the drawing recognition unit 2 can be used when a plurality of characters are included in the drawing and the links are generated separately. Since there is a position in the drawing, it is possible to easily grasp the correspondence between the character string for creating the link and the drawing. Further, the drawing recognition unit 2 may be omitted when a drawing, a character string, or the like is already input to the drawing data 1.

  The ID list-up unit 3 extracts a character string common to the drawings as an ID and registers it in the ID index 4. A character string to be extracted may be input by a person, or a character string extracted by the drawing recognition unit 2 may be used as a character string to be extracted. In the extraction, the drawing data in the drawing database 1 is searched for a drawing having the same character string as the character string. At this time, an ID included in the dictionary may be extracted from the drawing using an ID dictionary that specifies the ID.

  The link generation unit 5 automatically generates a link between two or more drawings or when there are a plurality of character strings extracted as IDs in the drawing and registers them in the link information 6. The link may hold the link information 5 for each work mode so that the link can be customized according to the work mode. A link can be opened by calling the other drawing from one drawing to another drawing registered in the link information. In an operation in which the browsing flow is drawing type A → drawing type B → drawing type C, if the link is pasted, the next drawing can be viewed with just one click. If the link is not pasted, it takes time to go back to the ID search screen and reselect the next drawing. Details will be described later.

  The browsing unit 7 has a display unit and an input unit. When the user specifies an ID part that is a character string in the drawing currently being viewed on the display unit, the part of the drawing ID linked to the display unit is displayed on the display unit. Then, the ID part is highlighted. The input unit accepts a user operation and displays a necessary drawing. As a means for the user to specify an ID region in the drawing, a mouse that is an input unit or a tablet integrated with a display unit is used. Further, the work mode designation unit 8 receives the work mode designation, and the drawing is displayed according to the link information 6 corresponding thereto.

  The work mode designating unit 8 receives input from the user by the input unit with respect to the menu displayed on the display unit by the same display unit and input unit as the browsing unit 7. For example, in the case of cable connection work, menus such as “drawing confirmation”, “connection work”, and “sequence test work” are displayed on the screen, and selection is received from the user. Alternatively, if the work mode is automatically determined based on whether or not an input is made from a specific input device, the number of input operations may be small. For example, when an input is received from the reader 10 described later, since the viewer is at the site, the “connection work” or “sequence” at the site is used in the “drawing confirmation” work mode in which the drawing is confirmed at the office. The operation mode may be automatically changed to the test mode.

  Instead of the user specifying the ID part in the drawing currently being viewed on the display unit, the ID may be specified by the ID conversion unit 9, reader 10, and RFID information 11. An RFID is attached to an object such as a cable in advance, and the RFID and the ID of the object are associated with the RFID information 11 in advance. When the RFID is read, the reader 10 sends the RFID to the ID conversion unit 9. The ID conversion unit 9 searches for the received RFID from the RFID information 11, converts it to an associated ID, and passes it to the browsing unit 7. The browsing unit 7 searches the display unit for the ID received from the ID conversion unit 9 from within the drawing currently being browsed, and performs the same operation as that for selecting the ID part.

  The book browsing apparatus 200 is operated in the following procedure. First, the user (1) reads a paper drawing with a scanner or the like to make an image file. Then, (2) input the attribute data of the image file as follows, for example.

File name: ECWD1.TIF
Data type: “Cable connection diagram”
Customer name: “Company H”
Construction name: “H plant T part A board replacement”
Date: July 16, 2008 Further, (3) register the image file with the attribute data attached to the book browsing apparatus 200, and start the book browsing apparatus 200. The book browsing apparatus 200 may be less time-consuming if the system registration file is detected so that it can be automatically started without any user operation. (4) From the above, the link information 6 is obtained as the output result of the book browsing device 200, and the operations shown in FIGS. The system operation at this time will be described later with reference to FIGS.

  2 and 3 show examples of screen operations of the browsing terminal 100. FIG. The drawings displayed in FIG. 2 and FIG. 3 have a format (eg, tiff) that cannot be retrieved as a character string as an image, and the link information 6 has been generated in advance by the book browsing device 200 after the drawing is recognized.

  Reference numerals 7-100 to 7-105 in FIG. 2 are window screens, 7-104 and 7-105 are scroll bars, drawings are partially displayed inside, and the viewer operates the scroll bar. The necessary part of the drawing can be displayed. Reference numerals 7-101 to 7-103 are portions extracted as IDs and having links to others, and are shown by being surrounded by dotted lines. The color may be changed, or a mark indicating a link such as an underbar may be attached. By indicating the portion where the link is present, there is an effect that the portion where the link is not generated due to erroneous recognition can be recognized. Also, if the recognized part is shown, it is displayed including misrecognition and is confused in operation, so displaying only the part with the link has the effect of avoiding confusion. 1-106 is the attribute content of the drawing, which is not normally displayed on the screen. On the toolbar 7-100, buttons 7-107 to 7-110 are arranged. The operation by this button will be described later. The contents of FIG. 3 are the same as those of FIG.

  In the link information 6, 7-202 of the wiring table shown in FIG. 3 is registered as a link destination 7-102 of the cable connection diagram of FIG. When 7-102 in FIG. 2 is instructed with a mouse or the like, the screen in FIG. 3 is displayed and the region 7-202 is highlighted. The highlighting should be different from the part with the link.

  In preparation for a case where the viewer wants to browse a drawing including the same ID other than the link destination, the following operation may be accepted.

  The buttons 7-107 to 7-110 are arranged on the toolbar 7-100 in FIG. Within the same drawing, button 7-107 retrieves the next ID site. If there are multiple IDs in the same page image, the first ID may be highlighted and the next ID may be highlighted with buttons 7-107, or all ID parts on the same page may be highlighted, In 7-107, a page including an ID after the next page may be displayed. Button 7-107 retrieves the previous ID part, button 7-108 retrieves the ID part of the next page, button 7-109 retrieves the ID part of the previous page, and button 7-110 retrieves the previous part. The ID part of the page is searched.

  In order to display a drawing list having IDs other than the link destinations, if 7-102 in FIG. 2 is designated by right-clicking with a mouse or the like, for example, as shown in FIG. “Cable connection diagram”, “Wiring table”, “Conduit diagram”, “Tray diagram” are displayed as items, and “Minutes”, “Update management table” and individual drawings as subcategory items, Image A, image B, and image C can be designated. The contents of the ID index may be referred to by the viewer. Thus, when referring to an approximately fixed drawing, the drawing to be referred to next can be displayed with a simple operation, and when necessary, the drawing to be displayed next can be selected.

  Even if the link destination is displayed, it is not the drawing that the user wanted to browse, but if the user reached the drawing to be browsed by right-clicking 7-107 to 7-110 or 7-102, the original link By replacing the destination with the destination, you can view the target drawing with less effort from the next time. For this purpose, although not shown in FIG. 2, a re-link destination menu button is provided in the same screen, and when this is selected, link information described later is replaced with the destination. In order to prevent the link from being mistakenly replaced, when the link destination pasting menu button is selected, the contents of the link destination pasting are displayed, the user is asked for confirmation, and the user presses the OK button.

  FIG. 5 shows a configuration example of the ID index 4. Reference numeral 4-100 denotes an index table indicating which image data includes a character string extracted as an ID. Reference numerals 4-101 to 4-106 are data for holding at which position in each drawing the ID is present. In the example shown in the figure, the ID RI077A01 is included in the ECWD1.TIF and CCL1.TIF drawings, and the rectangular part having the diagonal line of the coordinates (x1, y1) (x1 + w1, y1 + h1) of the 1st page in ECWD1.TIF. (4-101). w1 is a rectangular width size, and h1 is a rectangular height size. In the case of a drawing that is not an image, a data holding method may be used in which the position in the drawing is from l1 page, m1 row, n1 column to l2 page, m2 row, n2 column.

  FIG. 6 shows a configuration example of the link information 6. The ID index shown in FIG. 5 is copied and a link destination is added. In the illustrated example, the ID RI077A01 is included in the ECWD1.TIF and CCL1.TIF drawings. Data indicated by 6-101 to 6-106 is link information. If the data indicated by RI077A01 to 6-101 located in the rectangular part having the diagonal line of the coordinates (x1, y1) (x1 + w1, y1 + h1) of the 1st page in ECWD1.TIF is specified, the coordinates of the jth page of CCL1.TIF This is link information for instructing that the portion of RI077A01 (data indicated by 6-101) located in a rectangular part having a diagonal line of (x5, y5) (x5 + w5, y5 + h5) is displayed on the screen. In the example of FIG. 6, all the link destinations of the RIWD77001 of ECWD1.TIF are the same RI077A01 part of CCL1.TIF. Also, RI077A01 of CCL1.TIF that has no downstream drawing in the reference flow order is linked to RI077A01 that appears next to the same data. If a reception screen for setting this link is provided and can be specified manually, it can be specified in accordance with the reference order of the user, but it is troublesome when there is a huge amount. According to the procedure described later, a link can be generated without human intervention. Although FIG. 6 has been described with a system having a list structure, other structures may be used.

  FIG. 9 shows an example of data in the order of reference flow. Data such as the flow order of reference is a rule when a link is generated by the link generation unit. This rule is recorded in the ID index database 4, but may be recorded in another database. Shows the order by the attribute value of the drawing type of the drawing, but attribute values such as hierarchy (the higher the hierarchy, the reference flow order comes first), date (the newer the date, the reference flow order comes first) The order is also acceptable. Further, the order may be indicated for each attribute type, and the priority order among the attribute types may be indicated. For example, by setting a rule that prioritizes the priority between attribute types by drawing type> hierarchy> date, if there are drawings with different dates between the same drawing type and hierarchy, the newer the date, the more the reference is made. The flow order comes first. Alternatively, the order may be directly associated with the image names. If the flow order by attribute type and the flow order by image name contradict each other, the former may be used, but special circumstances can be taken into account if the latter flow order is adopted. In addition, the link may be generated only for the one with the highest priority. In this way, since other link candidates are not displayed, it is possible to avoid complicated display. In addition, the links are set to be in the flow order, but if the operator determines that the original link destination is wrong and changes the link destination to another character string, the flow order data is also corrected and correct. By switching to the link destination, the target drawing can be viewed immediately from the next time. For example, in the reference flow of FIG. 9, when the operator is referring to the first cable connection diagram of the reference flow and the link destination is changed to the tray diagram, the fourth tray of the reference flow data is displayed. Change the figure to the second link in the cable connection diagram. At the same time, the wiring table that was second in the reference flow is changed to the third. Similarly, the subsequent flow is changed to the subsequent flow one by one. By changing the flow order in this way, the link order of the tray diagram and the wiring table is also determined, so that the link relationship with the order after the changed order can be matched without any contradiction due to the change.

  FIG. 7 shows an operation flow of the book browsing apparatus 200 of FIG. When it is detected in step 7-1 that the drawing has been registered or updated by the function of the computer not shown in FIG. 1, in step 7-2, the drawing recognition unit 2 determines whether the image data does not include a character string. If so, the drawing is recognized in step 7-3.

  In step 7-4, the ID list-up unit 3 lists the IDs in the drawing and registers them in the ID index 4. This is done by the following procedure. First, a character string that can be an ID is extracted from a drawing and registered in a drawing-specific index. Register and create a drawing-specific index for all registered drawings. Then, with respect to all IDs of all the drawing-dedicated indexes, whether or not the IDs are included in other drawings is examined by searching, and if included, it is registered in the ID index 4. Alternatively, the following procedure is used. An ID included in the dictionary is extracted from the drawing using an ID dictionary that specifies the ID.

  In step 7-5, the link generation unit 5 generates link information and registers it in the link information 6. Details of the procedure 7-5 are shown in FIG.

  In step 7-1, instead of detecting whether the drawing has been registered or updated by the function of the computer, the user may activate the operation. When image data is not targeted, procedures 7-2 and 7-3 are not necessary. Further, when only the image data is compared, step 7-2 is not necessary, and step 7-3 is performed after step 7-1.

  FIG. 8 shows an operation flow of the link generation unit 5.

  It repeats until it complete | finishes about all ID which added or updated the link information 5 in the procedure 8-1. In step 8-2, the drawings including the ID are arranged in the order of reference. The reference flow order is performed as described in the explanation of FIG. Until all the drawings including the ID are completed in the procedure 8-3, the following is performed from the drawing having the higher reference flow order. In step 8-4, it is determined whether or not there is a next drawing having the reference flow order. If there is, a link to the first ID of the next drawing having the reference flow order is registered in step 8-5. At this time, with only the attribute type having the highest priority, when there are a plurality of drawings as reference destinations, it is preferable to select one drawing that is prioritized from other attribute types (eg, hierarchy, date). Also, when the same ID appears repeatedly in the same drawing, a rule is set such that the first ID is set. If the user is not satisfied with the display of the link destination, the link can be traced to the desired position by using the buttons 7-107 to 1-110 shown in FIG. 2 and the function shown in FIG. If there is no next drawing in the reference flow order, a link to the next ID of the same drawing is registered in step 8-6.

  FIG. 10 shows a configuration example of the RFID information 11. For specifying an ID for searching for a necessary drawing, it is easy to specify the ID on site using RFID or the like. Here, it is shown that the RFID having the suffix 9F661F4B is attached to the core number 1 of the cable EE55D02. In the state of FIG. 2, instead of the user specifying the ID part that is the character string in the drawing currently being viewed on the display unit, the reader can read the RFID so that the ID that is the character string can be specified. In order to do so, the following functions are provided. That is, the ID conversion unit 9 searches the RFID information database 11 for the RFID read by the reader 10, and obtains an ID (cable number, terminal number, etc.) that is a character string associated with the read RFID. Then, the obtained character string ID is searched from the drawing being displayed. The searched character string includes a cable number, a terminal number, and the like. The ID that first appears after the cursor position displayed in FIG. The browsing unit 7 displays the drawing linked there on the screen. Instead of searching for the first ID to appear after the cursor position, priorities are set for ID types (cable number, terminal number, etc.), and the target drawing can be displayed quickly by searching in order from the highest priority ID. . The order may be the order from the beginning of the drawing (from FIG. 6, “next” is obtained in order to obtain data, but the order is not) from the cursor position. There is an advantage that the target book can be browsed from the RFID.

  In order to refer to the drawings on site, it is necessary to be able to browse according to the work, so this link automatic generation function is very useful.

  In addition, this invention is not limited to an above-described Example, Various modifications are included. For example, the above-described embodiments have been described in detail for easy understanding of the present invention, and are not necessarily limited to those having all the configurations described.

  The apparatus according to the above-described embodiment can be implemented by a computer having a storage unit or a CPU. The processing unit as a function of the apparatus is a program module, and the module is read and executed by the computer. Each function can be implemented. In addition, each of the above-described configurations may be configured such that some or all of them are configured by hardware, or are implemented by executing a program by a processor. Each function can be implemented by causing a computer to read a recording medium on which a program module is recorded.

  In the above-described embodiment, each function and each database are provided in each device and processing is executed. However, each processing is executed by a separate device and communicates between the devices. Can also be executed. The database can also be executed by communicating with each other as a separate device.

  As described above, when a storage unit that stores drawing data, a list-up unit that searches for character strings common to a plurality of drawings in the drawing data, and a character string in the displayed drawing are selected, the searched character string Link candidates can be easily extracted by a book browsing system that has a link generation unit that generates links according to rules from links between character strings common to multiple drawings. In addition, it is possible to easily create a link for drawing display according to the field work procedure. If links are made in this way, in the process of browsing the drawing type A → drawing type B → drawing type C, if the link is pasted, you can see the next drawing with just one click. Can do. If the link is not pasted, it takes time to go back to the ID search screen and reselect the next drawing.

  A book having a storage unit for storing drawing data, a list-up unit for searching for a character string common to a plurality of drawings of drawing data, and a link generation unit for generating a link according to a rule for a character string common to a plurality of drawings The browsing device has the same effect.

Further, in a book browsing method of a book browsing apparatus having a storage unit for storing drawing data and a link generation unit for generating a link of the drawing, the book browsing device searches for a character string common to a plurality of drawings in the drawing data, The book browsing method of generating links according to rules for character strings common to a plurality of drawings has the same effect.

  Moreover, even if an image image of a character string is included in the image data, a keyword search can be performed on the character string by a book browsing method having a drawing recognition unit that distinguishes and recognizes an image and a character string in the drawing data. . Multiple drawings can be linked with a common character string.

  In addition, the browsing unit highlights the part in the drawing where the link destination corresponding to the position coordinate is generated so that the user can see and understand the location of the link in the drawing. I can know. The user can know the part where the character string could not be extracted due to misrecognition or the like.

  Further, the selection of the character string in the drawing of the browsing unit is not required by the book browsing system that inputs the character string by reading the RFID.

  In addition, a recording device that records a reference flow order table associated with the attribute of the drawing data, and the link generation unit, if there is a common character string in the first drawing and the second drawing, A book browsing system that creates links from the character string of the previous drawing to the character string of the drawing with the flow order can create a link that matches the flow of browsing according to the work, and can be browsed according to the work. .

  The flow of browsing can be changed for each business by a book browsing system having an input / output unit that accepts a change by the user. It can cope with changes in business procedures and browsing flow.

  The browsing unit searches for the next ID part in the same drawing, searches for the previous ID part in the same drawing, searches for the ID part of the next page, searches for the ID part of the previous page, If the link destination is not a target to be browsed by a book browsing system that accepts and executes any operation designation for displaying a drawing list having an ID other than the link destination, other drawings can be easily searched.

  In addition, when the browsing unit accepts an operation designation for re-linking the link destination from the user, the book browsing system that updates the flow order of the reference to follow the operation, if the original link destination is wrong, the correct link destination By swapping, the target drawing can be viewed immediately from the next time.
