Description

  The present invention relates to a drawing management system and a drawing management method for managing a drawing written on paper as electronic information, and more particularly to a drawing management system and a drawing management method for associating drawing information with attribute information.

  When planning inspections of plant piping parts and managing inspection results, if the technical standards are revised, it is necessary to newly define management attributes such as the scope to be inspected this time, the frequency of inspection, and the management rank. In addition, depending on the change in the operation state of the plant, it may be necessary to review the management attributes once defined.

  By the way, the drawings of existing plants are not digitized and are often written on paper. If not digitized in this way, for example, a color is defined for each management rank, and a highlighter of a color corresponding to the management rank is applied over the route of the management target (inspection location) on the paper drawing, so-called color separation A general method is to create a chart and a list of management targets and management ranks using spreadsheet software or the like.

  However, such manual work has a problem that work efficiency is low, and the color separation diagram as the work result also becomes a paper drawing, and it takes time and effort to save and manage. Also, when creating a list, it is common to extract the management target and management rank from the color map again and manually enter it into the spreadsheet software. There is a possibility that human error will occur during manual entry. There was a problem that there was.

  In order to solve the above-described problems, it is desired to manage a drawing written on paper as electronic information. Patent Document 1 proposes a conventional technique for managing (electronicizing) a drawing written on paper as electronic information.

  The prior art of Patent Document 1 is an image that is raster data by scanning a drawing written on paper for the purpose of improving the accuracy of digitization work when digitizing raster data and improving work efficiency. Is obtained and displayed as a background image on the display device, the newly entered table description information is obtained with respect to the description of the table indicated in the background image, and the newly entered table description information is used as the foreground image. Displayed and issued with a digital tag identification information that can identify a digital tag (corresponding to a symbol to be described later) composed of vector data of arbitrary shape pasted at the coordinate position of the management target on the graphic shown in the background image The digital tag is pasted on the figure shown in the background image, the digital tag is displayed as the foreground image, and the table description information and digital tag displayed in the foreground image are displayed. By associating based on the digital tag identification information, the drawing written on the paper is managed as electronic information.

  “Raster data” refers to data represented by a collection of pixels arranged in a grid. Since it is a collection of pixels, it does not have information such as the relationship with neighboring pixels or what the whole indicates. Raster data is sometimes called image data or an image.

  “Electronicization” refers to converting raster data into vector data.

  “Vector data” refers to the coordinates (position) of the start and end points of a line, if it is a curve, how to bend, thickness, color, color of the surface surrounded by the line, how to change, etc. by symbols or numerical values. It is expressed with easy-to-handle data. Furthermore, vector data can be handled as one aggregate in a computer, and attribute information can be added.

  “Attribute information” indicates information such as the name and what the data represents. There are no particular restrictions on the type and amount of attribute information.

  As prior arts for managing drawings written on paper as electronic information, the prior arts of Patent Document 2 and Patent Document 3 have been proposed.

~ Operation ~
When the management attribute of the management target is instructed, the worker creates a color separation diagram related to the management attribute classification and creates a list by using the drawing management system according to the present embodiment. This series of operations will be described in the order of advance preparation, color diagram creation, list creation, management attribute change (redefinition).

  The operation relating to the advance preparation will be described.

  Piping drawings used in a plant are currently often created using a computer such as CAD (Computer Aided Design), and are left and managed as electronic information. However, piping drawings of plants constructed in the past are often described on paper. An operator scans a paper drawing using a scanning device. The image which is the raster data obtained in this way is stored in the storage device 3 together with the drawing number.

  In the paper drawing, attribute information such as a management object ID, a pipe shape, a dimension, a product name, a material, a wall thickness, and a connection target pipe is described in a list form for each pipe that is a management target. When an operator scans a paper drawing using a scanning device, this list is also stored in the storage device 3 as raster data.

  The worker displays an image on the display device 2 and places a symbol at a position corresponding to the management target on the image. The symbol is, for example, oval graphic data (vector data) with an arrow, and is arranged so that the tip of the arrow indicates a management target. When the symbol is arranged, the coordinate of the arrow tip is detected as the coordinate of the management target on the raster data, and this coordinate is recognized as the symbol coordinate.

  The attribute information input table is linked to the symbol, and the operator displays both the attribute information input table and the raster data format list on the display device 2, and the attribute information input table is displayed while viewing this list. To enter. The characters in the list may be digitized by OCR, and the digitized character information may be input to the input table. Among the attribute information, the management target ID is displayed in a symbol ellipse. Each attribute information of the list input to the attribute information input table and the coordinates of the tip of the symbol arrow are stored in the storage device 3 and constitute first attribute information. It should be noted that only the management target ID and the coordinates of the tip of the symbol arrow constitute the first attribute information, and the other attribute information is linked to the first attribute information as another attribute information and stored in another area of the storage device 3. May be.

  Note that the method of creating a symbol (equivalent to a digital tag in Patent Document 1) and first attribute information as vector data from an image as raster data is simplified for convenience of explanation, but the conventional technique of Patent Document 1 is not used. Common to basic concepts.

  On the other hand, line segment definition data is created in advance (S10). The line segment definition data is stored in the storage device 3.

  An operation related to creation of a color map will be described.

  When inspecting and managing plant piping parts, it is necessary to define a new management attribute if the technical standards are revised. For example, the management rank is defined to be divided into rank A and rank B as management attributes. Then, a color is classified for each pipe to be managed, and a management attribute division diagram (color distribution diagram) is created.

  First, the operator displays an image and a symbol on the display device 2 (S20), and then displays a management attribute input table on the display device 2. FIG. 3 shows an example of the management attribute input table. In the management attribute input table, an attribute ID, an attribute category, and an attribute name are described. The attribute ID is an ID number automatically assigned by the system. The attribute category is a general term for management attributes, and in this embodiment, an operator inputs “management rank”. The attribute name is an item of the attribute category, and in this embodiment, the worker inputs “rank A” and “rank B”. Thereby, a management attribute is defined in this system (S30). The management ranks “rank A” and “rank B” are included in the second attribute information.

  Next, the operator displays the line segment definition data on the display device 2 and selects a line segment definition corresponding to each attribute ID from the displayed line segment definition data. In the line definition data, the color, thickness, type, etc. of the line segment are defined for a plurality of line segments, but these can be arbitrarily changed. FIG. 4 shows an example of the line segment definition data table. In the management attribute input table of FIG. 3, the attribute ID “00001” is “rank A”, and in the line segment definition data table of FIG. 4, the attribute ID “00001” has a thickness of “10 pt” in “red” color. It is a line segment consisting of “solid lines”. That is, the line definition of “red”, “10 pt”, and “solid line” is selected corresponding to the management rank “rank A”. Similarly, the line definition of “pink”, “5pt”, and “dotted line” is selected corresponding to the management rank “rank B”. Thereby, the line segment definition is selected in this system (S40).

  When the management rank of the management target ID “AA-0001” of the management target (for example, the inspection location) is “rank A”, the worker overlaps the management target (corresponding to AA-0001) on the raster data and displays the display device The object is drawn according to the line segment definitions of “red”, “10 pt”, and “solid line”. More specifically, several points representing the management object on the image are selected by the mouse (input device 1), and the points are connected by a line segment, whereby the object is drawn. As for the drawing method, the object may be drawn by moving the pointer by operating the mouse (input device 1) so as to trace the management target on the raster data. When the input device 1 is an input pen of a touch panel, the object may be drawn by moving the pen tip so as to trace the management target on the raster data. In any drawing method, the object is thereby displayed on the display device 2 (S50).

  In the process of drawing an object, a trajectory of the object is generated. The system detects the coordinates of the symbol of the management target ID “AA-0001” (S60), and associates the first attribute information and the second attribute information when the object drawing trajectory passes near the coordinates of the symbol. FIG. 5 shows an example of the association table. The attribute ID “00001” is input corresponding to the management target ID “AA-0001”. In the management attribute input table of FIG. 3, the attribute ID “00001” is defined as “rank A”, and as a result, the management target ID “AA-0001” and the management rank “rank A” are associated (S70). ).

  The association table is stored in the storage device 3. Also, attribute information that the management rank of the management target ID “AA-0001” is “rank A” is added to the first attribute information (S80).

  When the operator sets the subscript display function, the subscript “rank A” is displayed in the vicinity of the symbol of the management target ID “AA-0001”.

  FIG. 6 shows an example of the object table. In the object table, an object ID and an attribute ID are described. The object ID is an ID number automatically assigned by the system when creating an object, and is an identification number for identifying the drawn object. In the association table of FIG. 5, when the attribute ID “00001” is input corresponding to the management target ID “AA-0001”, the attribute ID “00001” is input corresponding to the object ID “OBJ0001” in the object table. The As a result, the object with the object ID “OBJ0001” is associated with the management target ID “AA-0001”.

  The association table and the object table, that is, the object and the management rank corresponding to the object constitute second attribute information, and the second attribute information is stored in the storage device 3 (S90).

  Similarly to drawing the object corresponding to the management target ID “AA-0001”, other management targets (other than the management target ID “AA-0001”) classified as the management rank “rank A” Draws an object according to the line segment definition of “red”, “10 pt”, and “solid line” so as to be displayed on the display device over the management target on the raster data (S50 to 90). With respect to the management target classified as “B”, an object is drawn based on the line definition of “pink”, “5pt”, and “dotted line” so as to be displayed on the display device so as to be superimposed on the management target on the image (S40 to 90). . Thereby, a management attribute division diagram (color diagram) is displayed on the display device 2 (S100). When the operator wants to use the color separation diagram as a paper drawing, the color separation diagram is printed using the printing device 5.

  The creation of the list will be described.

  In the process of creating a color map, the management target ID “AA-0001” and the management rank “rank A” are associated with each other, the other management target IDs are associated with the management rank, and the association is performed for each management target ID. As a result, a list is automatically created. The operator displays the list on the display device 2 by selection, and further prints the list using the printing device 5 by selection (S110). FIG. 7 shows an example of the list.

  The operation associated with the change of the management attribute will be described.

  At the time of the initial examination, the management rank was defined to be divided into rank A and rank B as management attributes. However, as a result of the subsequent examination, the management rank was newly divided into rank A, rank B, and rank C. May be redefined. It is assumed that the management rank of the management target ID “AA-0003” is changed from “rank B” to “rank C”, for example, in accordance with such a change in management attribute.

  First, the worker displays a management attribute input table on the display device 2 and inputs “rank C” corresponding to the attribute ID “00003” automatically assigned.

  Then, the operator displays the line segment definition data on the display device 2 and selects the line segment definition corresponding to “rank C” from the displayed line segment definition data. Assume that the attribute ID “00003” and, for example, the line definition of “orange”, “3pt”, and “broken line” are selected corresponding to the management rank “rank C”. In the line definition data table, attribute IDs “00003”, “orange”, “3pt”, and “broken line” are added.

  Since the management rank before change of the management target ID “AA-0003” is “rank B”, when the worker displays the object table, the attribute ID “00002” is described corresponding to the object ID “OBJ0003”. Yes. When the worker changes the description of the attribute ID “00002” to the attribute ID “00003”, the line segment definition of the object with the object ID “OBJ0003” is changed and displayed on the display device 2.

  On the other hand, in the association table before the change, the attribute ID “00002” is described corresponding to the management target ID “AA-0003”. However, when the object table is changed, the attribute ID “00002” is automatically changed. The description is changed to the attribute ID “00003”. That is, the management target ID “AA-0003” is associated with the management rank “rank C”. Further, the subscript displayed near the symbol of the management target ID “AA-0003” is changed from “rank B” to “rank C”.

  As a result, the color separation diagram after the management attribute change is displayed on the display device 2. A list after the change is also created automatically. In this way, it is possible to easily cope with changes in management attributes.

~effect~
The effect of this embodiment will be described in comparison with conventional manual work.

  As an example of a conventional manual operation, a color is defined for each management rank, and a highlighter of a color corresponding to the management rank is applied on the route of the management target (inspection point) on the paper drawing, and the management target and the management rank are determined. There is a method of creating a list of management targets and management ranks by using association software, so-called color separation diagrams, and using spreadsheet software.

  However, such manual work has a problem that work efficiency is low, and the color separation diagram as the work result also becomes a paper drawing, and it takes time and effort to save and manage. When creating a list, it is common for an operator to re-extract and associate management targets and management ranks while visually observing a color distribution diagram, which is a paper drawing, and manually enter it into spreadsheet software. There is a problem that there is a possibility that a human error may occur during manual input due to poor extraction and poor work efficiency related to association.

  If the drawing management system of this embodiment is used, a color separation diagram can be easily created by drawing an object on the management target displayed on the display device 2, and the work efficiency of color separation diagram creation can be improved. The drawing management system reproduces a conventional manual process on the display device 2 and can be easily operated even for an operator who is used to the conventional manual process. Since the created color separation chart is stored in the storage device 3, work efficiency related to management can be improved.

  The drawing management system of the present embodiment associates the first attribute information and the second attribute information when the trajectory of the object drawing passes near the coordinate position of the symbol in the process of creating the color map. In the above description of the operation, when the object with the object ID “OBJ0001” is drawn, the management target ID “AA-0001” and the management rank “rank A” are automatically associated. Thereby, the work efficiency concerning an association can be improved. In addition, since it is automatically associated, human error can be prevented.

  In other words, the effects of improving the work efficiency of this association and preventing human error will be further described. In the conventional manual work and the work by the drawing management system of this embodiment, the operator identifies the management object while looking at the piping drawing, and performs the color coding while associating the management object with the management attribute. Are common. However, in the conventional manual work, after creating the color separation diagram, the management target and the management rank are again extracted and associated, and manually input to the spreadsheet software, whereas the drawing management system of the present embodiment At the time of creating the color map, the list is automatically created. That is, the drawing management system of this embodiment functions as an input terminal with excellent operability. As a result, the effect of improving the work efficiency of association and preventing the occurrence of human error can be obtained.

  On the other hand, the drawing management system according to the prior art of Patent Document 1 does not have a configuration for creating a color separation diagram and cannot create a color separation diagram, but it does not mean that work related to the association and creation of a list cannot be performed. . That is, the first attribute information is added to the symbol to be managed (corresponding to the digital tag), and the worker adds the management attribute corresponding to the attribute information for each symbol by using the attribute information input table. I'll do it. Specifically, the management rank “rank A” is added to the attribute information added to the symbol of the management target ID “AA-0001”, and the attribute information added to the symbol of the management target ID “AA-0002” Add the management rank “Rank B”. However, such work has poor work efficiency, and furthermore, since visual confirmation cannot be made without referring to a color diagram, there is a problem that human errors are likely to occur. In the drawing management system according to the prior art of Patent Document 1, the attribute information input table is the input means, whereas in the drawing management system of the present embodiment, object drawing is the input means. By using the drawing management system of the present embodiment, the worker can efficiently perform work without human error while visually confirming the color diagram. That is, even when compared with the drawing management system according to the prior art of Patent Document 1, the effects of improving the work efficiency of association and preventing the occurrence of human error can be obtained.

  Furthermore, the drawing management system of this embodiment can easily create, display, and print a list. In addition, it is possible to easily cope with changes in management attributes.

<Other embodiments>
-Second embodiment-
The storage device 3 of the drawing management system according to the first embodiment includes a second storage unit 32 that stores first attribute information and a fourth storage unit 34 that stores second attribute information. The attribute information is stored in the fourth storage unit 34 and additionally written in the first attribute information and stored in the second storage unit 32. However, the management attribute is stored only in the fourth storage unit 34 as the second attribute information. Also good. That is, it is not always necessary to add the management attribute to the first attribute information.

  The attribute ID is described in the management attribute input table (FIG. 3), line segment definition data table (FIG. 4), association table (FIG. 5), and object table (FIG. 6) shown in the operation description of the first embodiment. The management object and the management attribute can be associated with each other through the attribute ID.

  Other configurations are the same as those of the first embodiment, and the same effects as those of the first embodiment can be obtained.

-Third embodiment-
The storage device 3 of the drawing management system according to the first embodiment includes a second storage unit 32 that stores first attribute information and a fourth storage unit 34 that stores second attribute information. You may have only the 2nd memory | storage part 32 to memorize | store.

  The management attribute is added to the first attribute information and stored in the second storage unit 32. In the first attribute information after the additional writing, the management target and the management attribute can be associated.

  When the fourth storage unit 34 is not provided, it is not possible to store an object among the second attribute information. However, it is important to create a list of associations between management targets and management attributes, and there are cases where storage management of color diagrams is not necessary. In such a case, even if the fourth storage unit 34 is not provided, it is possible to obtain the effects of improving the work efficiency of association and preventing the occurrence of human error. Further, since the fourth storage unit 34 is not provided, the capacity of the storage device 3 can be reduced and the system configuration can be simplified.

-Fourth embodiment-
Although the drawing management system according to the first embodiment includes the printing device 5 and the printing function 47, it is not always necessary.

  It is important to create a list of associations between management targets and management attributes, and there are cases where it is not necessary to print a color diagram or list. If the list is displayed on the display device 2, the operator can confirm the relationship between the management object and the management attribute.

  That is, even if the printing apparatus 5 and the printing function 47 are not provided, the effect of improving the work efficiency of association and preventing the occurrence of human error can be obtained. Further, since the printing apparatus 5 and the printing function 47 are not provided, the system configuration can be simplified.

-Fifth embodiment-
The association function 45 of the control device 4 of the drawing management system according to the first embodiment includes the association function 45 when the trajectory of the object drawn using the input device 1 passes the coordinate position of the symbol or the vicinity thereof. Although the first attribute information (which constitutes the symbol to be managed) and the second attribute information (including the management attribute) are associated, the control function related to the association is not limited to the association function 45.

  The association function 45A (not shown) of the present embodiment associates the first attribute information and the second attribute information when a drawn object is selected and a corresponding symbol is selected.

  For example, the operator draws an object with the object ID “OBJ0001” by the line segment definition corresponding to the management rank “rank A”, selects this object with the input device 1, and then selects the object with the management target ID “AA-0001”. Select a symbol. After selecting the symbol, the object may be selected. As a result, the management target ID “AA-0001” is associated with the management rank “rank A”.

  Compared with the operation of the drawing management system according to the first embodiment, the operation of the drawing management system according to the present embodiment requires a procedure of symbol selection and object selection by an operator and is inferior in terms of workability. However, as compared with the conventional manual work, the effect of improving the work efficiency of association and preventing the occurrence of human error can be obtained.
