Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a drawing management method and apparatus for digitizing and managing facility drawings such as hot water and gas piping systems, and electric and telephone wiring systems.

[Conventional technology]

2. Description of the Related Art Conventionally, status management of facilities such as piping such as water supply, gas, electricity, telephone, and wiring systems has been performed using drawings drawn on paper or polyester film. At this time, if a change occurs in the facility, it is necessary to correct the drawing. All drawing correction operations must be performed manually, which requires much labor and time, and has a high rate of erroneous writing. In order to solve this problem, for example, as described in Japanese Patent Publication No. 61-9667, it has been proposed to convert facility drawings into digital information and manage them. In order to manage the facility drawings by converting them into digital information, a large number of facility drawings (topographic maps, system diagrams, symbol maps, etc.) stored in the file device are displayed on the display device on a monitor. In addition, the work of correcting the drawing is also displayed on the display device.

[Problems to be solved by the invention]

By the way, when a facility drawing is converted into digital information and managed, it is necessary to know the detailed contents (attributes) of a specific figure (hereinafter referred to as a designated figure) in the facility drawing. For this reason, the attribute information is also stored in the file device and displayed on the display device. When displaying the attributes, it is desirable to simultaneously display the facility drawing and the attribute data on the display device so that the relationship between which designated figure and the attribute can be understood. In order to simultaneously display the facility drawing and the attribute data, it is conceivable to fixedly define and display an attribute display area on the display surface of the display device. However, the attribute data does not need to be constantly displayed, but is displayed only when necessary. It is desirable that the attribute data be displayed in a window superimposed on the facility diagram from the viewpoint of effective use of the display surface of the display device. However, if the position of the attribute display window is fixed to a specific position on the display surface, the shape of the designated figure in the drawing differs depending on the figure in both the length direction and the area, and the designated figure to be managed and the attribute display window area overlap. Sometimes. When the attribute display window and the designated graphic overlap, it is possible to avoid such a problem by changing the display range of the facility drawing. However, since the display range of the facility drawing is changed, the positional relationship between the designated figure and the deleted figure cannot be grasped, so that there is a problem that the management becomes inconvenient and the display range changing operation becomes troublesome.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and an object of the present invention is to provide a drawing management method and apparatus capable of easily avoiding duplication of a designated figure and an attribute display window and facilitating drawing management. is there.

[Means for solving the problem]

According to the present invention, when the divided facility drawing and the attribute are simultaneously displayed on the display device, the attribute display window is moved when the attribute display window and the designated figure of the divided facility drawing overlap.

Further, the present invention makes the size of the attribute display window area variable.

[Action]

The attribute display window moves to a position other than the position of the designated figure in the facility drawing. Thus, the attribute display window and the designated figure can be displayed without overlapping without changing the display range of the facility drawing. Therefore, it is easy to grasp the positional relationship between the designated graphics, and the operation can be performed easily. Further, the size of the display area of the attribute display window is variable, and the attribute data can be enlarged or reduced to characters of a size that is easy for the operator to see, so that erroneous connection is prevented.

〔Example〕

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

FIG. 2 is a basic configuration diagram of a drawing management apparatus according to an embodiment of the present invention.

In FIG. 2, facility drawing data is stored in the file device 203. The facility drawing data includes graphic data such as a topographic map and a pipe map, and attribute data expressed by characters and numerical values such as a town name, a personal name, a management diameter, and a pipe type related to the graphic. The stored graphic data is input from a drawing input device 204 which scans a drawing drawn on a paper at regular intervals, converts the drawing into gray scale according to the gray scale of the read data, obtains a digital image, and obtains coded data. Facility drawing is 3rd
As shown in FIG. 7A, the drawing is composed of a plurality of drawings, and each is divided to form a graphic data file. The graphic data is shown in an orthogonal coordinate system as shown in FIG. 3 (b), and the lengths X ₀ and Y ₀ in the X and Y axis directions are determined by the drawing size. These graphic data have a data storage structure that is hierarchically separated from roads, house frames, and pipelines as shown in FIGS. 4 (b) to 4 (d). These data are superimposed on each layer as necessary to form graphic data as shown in FIG. 4 (a). On the other hand, the attribute data is input to the file device 203 using a data input device 208 such as a keyboard 206 or a floppy disk capable of inputting data collectively. In order for the operator to operate the mouse 207 to display a drawing on the display device (CRT) 205, the operator first operates the mouse 207 to move the cursor CU to the function selection icon displayed on the CRT screen. To specify. When the "draw drawing" icon is specified, the central processing unit (CP
U) 201 retrieves the corresponding drawing data (graphic data and its attribute data) from the file device 203 and temporarily stores it in the main memory 202. The main memory 202 functions to store a program for executing processing such as drawing data search and editing and data being processed. After the drawing data temporarily stored in the main memory 202 is edited by the CPU 201 in accordance with the effective display coordinates of the display area of the CRT 205, the CRT 2
Displayed at 05. The operator can know the contents of the target drawing from this display screen. By the way, in the CRT display area shown in FIG. 5B, the original size of the input drawing shown in FIG. 5C is often smaller than that in FIG. 5A. In order to grasp a detailed part, the part is enlarged and displayed as shown in FIG. 5 (c). For this purpose, the cursor CU is moved by the mouse 207 to specify an arbitrary rectangular area from the CRT display area in FIG. Specifically, the main memory
A part of the corresponding drawing data stored in 202 is enlarged / reduced through the CPU 201 and displayed on the CRT 205.

Next, a description will be given of the display of attribute data when a target drawing is retrieved from the file device 203 and the drawing data is edited and displayed on the CRT 205 with reference to FIG. FIG. 1 shows an essential part of an embodiment of the present invention, and shows an example of an attribute data display processing unit of the CPU 201.

In FIG. 1, a display display surface 101 is a mouse operation icon area 102 for selecting a function for searching and correcting a target drawing, a drawing display area 103 for displaying a drawing searched by a mouse operation, and is currently displayed. An attribute display window 104 for moving the cursor of a target graphic from the drawing by a mouse operation to select and instruct the target graphic and displaying attribute data of a designated graphic portion. The attribute data displayed in the attribute display window is processed according to the following procedure. Using the mouse 207 shown in FIG. 2, a cursor CU that moves in one-to-one correspondence with the operation of the mouse 207 is moved to the icon area 102 on the display screen 101, and a command for selecting a "drawing search" icon is issued. This selection command indexes the corresponding drawing data from the file device 203 via the CPU 201 and temporarily stores it in the main memory 202. In the CPU 201, the drawing data is edited in accordance with the drawing display area 103 and displayed in the drawing display area 103. In order to search the display drawing for additional facility information relating to the designated figure, that is, attribute data, the user operates the mouse 207 to move the cursor CU to the corresponding figure and select the designated figure. The attribute search graphic designating unit 106 selects graphic data corresponding to the cursor position. Next, the attribute data linked to the graphic data is stored in the attribute search unit 10.
According to 8, the attribute file is retrieved from the attribute file of the graphic / attribute file unit 107 and edited by the attribute editing unit 109 in accordance with a predetermined editing item. The attribute display window coordinate determining unit 110 determines the display position of the attribute display window from the graphic coordinate position specified by the attribute search graphic specifying unit 106.

FIG. 6 shows a display position determination processing flow of the attribute display window coordinate determination unit 110.

In FIG. 6, from the state before the movement shown in FIG. 7B, first, in step 301, an icon of "move" instructing a window movement request in the attribute display window is selected by operating the mouse 207 (FIG. 6). (FIG. 7 (b)). When the operation icon of “move” is displayed in the attribute display window 104, the attribute display window 104 can be moved irrespective of the display state change operation of the facility drawing displayed on the screen display area 103 of the CRT 205. Next, step 3
In step 02, the cursor CU is moved to the position where the window is to be moved, and the coordinates of the reference point, which is the coordinates of the lower left corner of the window, are designated and input. In order to find out the coordinates of the currently displayed window reference point, the coordinates are indexed in step 303. The reference point coordinates are the reference point A ₀ (X ₀ , Y ₀ ) at the lower left of the attribute display window 104 in the graphic display area 103 as shown in FIG. _{For 1} (X ₁ , Y ₁ ), the reference point A ₀ is designated to move to an arbitrary position by operating the mouse 207. In step 304, the attribute display position is converted into the attribute data display start point coordinates in the attribute window accompanying the movement of the reference point coordinates in the attribute window 104, and in step 305, the graphic area of the background figure overlapping the attribute window 104 is erased. . Attribute window 10 is displayed in the area where this background figure has been deleted.
4 is displayed in step 306. In step 307, the pre-move window which is no longer necessary due to the window movement is deleted, and the display of the background image overlapping the attribute window is restored. The display as shown in FIG. 7C is made on the display surface of the CRT 101.

FIG. 8 shows a display example of attribute data displayed in the attribute display window 104. Attribute data is alphanumeric
This is character data composed of Chinese characters.

The attribute data is displayed as described above.
Since the attribute display window is moved so as not to overlap the designated figure, the attribute data can be displayed without changing the display range of the facility drawing. Therefore, it is easy to grasp the positional relationship between the designated graphics and the operation can be easily performed.

 FIG. 9 shows another embodiment of the present invention.

The amount of attribute data differs depending on the designated figure and the user. When the area of the attribute display window is fixed, the displayed characters become smaller as the number of items increases. Therefore, it is desirable to arbitrarily enlarge the attribute display window area and enlarge the display characters in accordance with the enlargement ratio so that the character size is easy for the user to see.

FIG. 9 shows an embodiment in which the attribute display window area can be arbitrarily enlarged.

9 differs from FIG. 1 in that an attribute display window enlargement ratio input unit 113 for designating the enlargement ratio of the attribute display window 104 to the attribute display window coordinate determination unit 110 and an attribute display window enlargement process corresponding to the enlargement ratio are performed. That is, the enlargement processing unit 114 to be performed is added.

 The operation will be described with reference to a flowchart shown in FIG.

First, in step 401, the “enlarge” icon attached to the attribute display window 104 is operated and selected with the mouse 207.
Next, in step 402, the icon position of "enlarge" at the lower left of the window is designated to the size to be enlarged. The designated coordinates are taken into the attribute display window enlarged position input unit 113. In step 403, the attribute display window enlargement processing unit 114
Then, an enlargement ratio is calculated from the enlargement position coordinates and the reference point coordinates. Step 404 also changes the character size of the attribute data contained in the attribute display window in accordance with the enlargement ratio. Further, in step 405, the display position coordinates are converted in accordance with the enlarged position coordinates. The result is a step
At 406, the attribute is sent to the display editing unit 111, and the attribute display window is enlarged and displayed.

When the attribute display window area is reduced, it is needless to say that the enlargement ratio can be made smaller than 1 in the same manner.

 FIG. 11 shows a main part of another embodiment of the present invention.

FIG. 11 shows an embodiment in which when a corresponding figure displaying attribute data is designated, the attribute display window is automatically moved and displayed to a position not overlapping the designated figure.

11 differs from FIG. 1 in that a figure designation position block allocation number determination unit 116 and an attribute display window coordinate automatic determination unit 117 are added.

In order to know the attribute data of the designated figure from the drawing display area 103, the user moves the cursor CU to the designated figure by operating the mouse 207 and designates the figure. The figure designation position 115 is sent as the figure coordinate position information to the figure designation position block assignment number determination unit 117 via the attribute search figure designation unit 106. The drawing display area 103 is divided into blocks as shown in FIG. 12 (a), and a block number 106 is assigned to each block. The figure designation position block assignment number determination unit 116 determines which block number 1 on this block assignment
Decide if it falls under 06. The figure designation position 115 is represented by (X, Y) coordinates in a rectangular coordinate system. Each X, Y coordinate is divided by the number of divisions in the X and Y directions of the block, and which block number
Decide if it falls under 112. As shown in FIG. 12 (b), it is necessary to select a block number which does not overlap with the graphic designated position as shown in FIG. 12 (b). This block number corresponding to the movement is created in advance as a correspondence table between the block number of the figure designated coordinate and the destination block number of the attribute display window 104 as shown in FIG. The attribute display window coordinate automatic determination unit 117 determines the block number to which the attribute display window is moved by referring to the correspondence table of FIG. 12C stored in the main memory 202. The position of the attribute display window 104 is determined using the lower left portion of the determined block number as the reference coordinates of the attribute display window 104, and the attribute data is sent to the display editing unit 111. As a result, the attribute data is stored in the display editing unit 1.
It is displayed at a position distant from the figure designation position in the drawing display area 103 via 11.

〔The invention's effect〕

As described above, according to the present invention, the attribute display window for displaying the attribute data for the specified graphic on the display screen can be moved to the position where the specified graphic does not overlap the window with respect to the specified coordinate position. At the same time without duplication. And by moving the attribute display window, it is possible to simply avoid duplicate display,
In addition, the positional relationship of the designated figure can be easily grasped. Also,
Since the attribute display window can be enlarged or reduced to an arbitrary size, the character size can be easily viewed according to the user, and can be realized without giving any limitation to the user.
