Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention digitizes drawings representing facilities such as water and gas piping systems, electricity, and telephone wiring systems, and manages drawings for layer management of graphic groups. More particularly, the present invention relates to a drawing management method, a drawing management apparatus, and a drawing display method suitable for easily identifying a group of figures belonging to the same layer in a drawing.

[Conventional technology]

As described in Japanese Patent Application Laid-Open No. 63-254565, there is proposed a drawing management device which manages drawings representing facilities by converting them into digital information. In this conventional drawing management device, an operator performs various operations such as correction of drawings while viewing the drawings (topographic map, system diagram, symbol diagram, etc.) displayed on the display device.

[Problems to be Solved by the Invention]

In order to manage a wide variety of graphic information, the drawing management device hierarchically manages graphic data and the like, and the hierarchy is changed for each type of facility. Then, when the drawing is displayed on the display device, the graphic information of each layer is superimposed and displayed. When the drawing management device is going to perform detailed management of each facility, it can be dealt with by increasing the number of layers. However, on the other hand, when drawing information of a large number of layers is superimposed and displayed on the display device, the figure data of each layer are mixed and dense, so that the arrangement of figures belonging to a certain layer in the entire drawing is changed. It becomes difficult to understand whether or not it is, and the operability of the drawing management device deteriorates.

An object of the present invention is to provide a drawing management method, a drawing management apparatus, and a drawing display method capable of visually recognizing, at a glance, graphic data belonging to an arbitrary designated hierarchy among drawings displayed on a display device. is there.

[Means for Solving the Problems]

The above-mentioned object is to display the drawing information on the screen when a hierarchy emphasis instruction is input in the drawing management in which the drawing information is hierarchically stored in the file device and the drawing information read from the file device is superimposed and displayed on the screen. When an arbitrary figure is designated in the displayed drawing, the figure information of the layer to which the figure relating to the designation belongs is displayed by emphasizing it from the drawing information of other layers.

[Action]

If you want to emphasize the hierarchy, all you have to do is specify a figure and all figure data in the hierarchy to which the figure belongs will be highlighted on the screen. Which figure is the target facility figure in the entire drawing? It is easily visible.

〔Example〕

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

The CPU 201 performs overall management and processing, and the main memory 202 and file device 20 are connected to this CPU 201 via the common bus 100.
3, drawing input device 204, CRT 205, keyboard 206, floppy disk 208, mouse 207 are connected.

The drawing input device 204 scans and reads a drawing written on paper at regular intervals, and creates graphic data in which light and shade are converted according to the light and shade of the read data.

The file device 203 stores facility drawing data. The facility drawing data is composed of graphic data and attribute data. The graphic data is data input from the drawing input device 204, and the attribute data is data input via the keyboard 206, the floppy disk 208, or the like. Here, the graphic data is data obtained by scanning the facility drawing by scanning with the drawing input device 204, and expressing the topographic map and the control chart. Attribute data refers to data represented by letters and numerical values such as town names, individual names, management diameters, pipe types, etc. related to topographic maps and control maps.

The CRT 205, keyboard 206, and mouse 207 are devices for man-machine. The main memory 202 stores software for CPU and various work data. Floppy disk 20
8 is also a kind of input device, has software and various databases, and is sent to the main memory 202 and file device 203 for use.

The structure of the graphic data is shown in FIG. FIG. 3 (a) is an example in which the graphic data is divided into meshes for each region and the meshes are numbered. This has the advantage that even a large facility drawing can be subdivided by division, easy to manage, and easy to perform man-machine processing.

FIG. 3 (b) is an example of a divided facility drawing. This division facility drawing is coordinated in the (X, Y) Cartesian coordinate system. By this coordinate conversion, it is possible to indicate the position and improve the man-machine processing function. Note that X0 and Y0 are graphic sizes.

The divided facility drawing of FIG. 3 (b) is not stored as it is, but is hierarchically stored. Fourth example of this
Shown in Figures (b), (c), and (d). The figure in FIG. 3 (b) is reproduced in FIG. 4 (a). This divisional facility drawing is made up of roads, house frames, and water pipes. Therefore, the divided facility drawing data has a three-layer structure in which the road figure data is the first layer data 42, the house frame is the second layer data 43, and the water pipe is the third layer data 44.

This hierarchical structure may be automatically obtained by the drawing input device 204 at the same time when the page is read, or may be read once and then hierarchically formed by software. If the road, the house frame, and the water pipe are displayed in different colors on the paper, the drawing input device 204 can read each color, and the three-layer structure data can be easily obtained.

With such a layering, roads, house frames, and water pipes can be processed separately, and if you want a superimposed display, you can select the layered data to be superimposed and perform a superimposed display.
It is possible to improve the processing capacity and expand the display capacity by freely selecting the hierarchy.

The operator operates the mouse 207 to operate the display device (C
To display a drawing on the RT) 205, the operator first operates the mouse 207 to move the cursor CU to the icon for function selection displayed on the CRT screen and specify it. If you specify the "Read Drawing" icon, the central processing unit (CPU) 2
01 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 has a function of storing a program for executing a process such as drawing data search and editing and data being processed. The drawing data temporarily stored in the main memory 202 is displayed on the CRT 205 after being edited by the CPU 201 according to the effective display coordinates which is the display area of the CRT 205. The operator can know the target drawing content from this display screen.

In addition, in order to grasp the detailed part, the part is enlarged and displayed. For this purpose, for example, the cursor CU is moved by the mouse 207, and a rectangular arbitrary area is designated at both ends on the diagonal line from the CRT display area to be enlarged or reduced to an arbitrary magnification.
Specifically, a part of the relevant drawing data stored in the main memory 202 is enlarged / reduced through the CPU 201 to be CRT2.
Display on 05.

Next, an example of highlighting only a specific hierarchy will be described with reference to FIG. In this example, when a target drawing is searched from the file device 203, the drawing data is edited and then displayed on the CRT 205, a specific hierarchy of the displayed drawing is highlighted by brightness.

The display screen 205A of the CRT205 is a display area for displaying a facility drawing.
In addition to 103, it has a hierarchy display area 104 for displaying a hierarchy and an icon display area 102 for displaying an icon. These areas 1
02, 103 and 104 are arbitrarily used according to the processing purpose.

The CPU 201 performs the hierarchical highlighting process according to the program of the main memory 202, and the processing content of this program is disclosed as the processing content of the CPU 201 for convenience in FIG. That is, the CPU 201 performs the processing of the operation input step 105, the hierarchy determination step 106, the highlighted display processing step 108, the non-highlighted display processing step 109, and the highlighted display editing step 111.

The main memory 202 has a graphic file 112, a hierarchical index table 107, a bright color / non-bright color table 110, in addition to various programs and work data (not shown).

The role of each area in the display screen 205A is as follows. The mouse operation icon area 102 is a place for instructing a function selection for searching and correcting a target drawing, and the drawing display area 103 is
Where the drawing retrieved by mouse operation is displayed or the hierarchical graphic data is highlighted, the hierarchical display area 104 displays the hierarchical name according to the operator's request, and the displayed hierarchical operation is selected by mouse operation. This is where you do.

Next, a procedure for highlighting hierarchical graphic data in the drawing display area 103 will be described. First, the icon is displayed in the icon area 102. In this state, the mouse 207 is operated to move the mouse cursor (CU) to “hierarchical emphasis” in the icon area. As a result, "hierarchical emphasis" can be selected.

When the CPU 201 reads that the icon pointed to by the mouse cursor on the icon is “higher hierarchy” (operation input step), it displays the hierarchy forming the graphic data in the area 104. The operator moves the cursor from the hierarchy being displayed in the hierarchy area 104 to the hierarchy to be highlighted, and the CPU 201 reads the hierarchy pointed to by the cursor as the hierarchy to be highlighted (tier determination step 106). Here, the displayed hierarchy is, in the example of FIG. 4, the road hierarchy data 42, the house frame hierarchy data 43, and the water pipe hierarchy data 44, and any one of these may be indicated by the cursor.

In the figure, figure file 112, hierarchy index table 107
However, there is an example in which the determination process is performed without using these two. That is, in the hierarchy determination step 106, when the hierarchy in which the cursor is designated in the hierarchy display area 104 is read, immediately the bright color table for highlighting the hierarchy being designated and the hierarchy not designated are not highlighted. The non-shining color table 110 is created. This table is shown in FIG. FIG. 6A is an example of the bright color table, and is in the hierarchy 1
An example in which the gradation is emphasized is shown. In this table, in addition to the selected layer number, gradation and color are also registered. The gradation and the color are preset in advance, and the preset values are incorporated when the table is created. Another method is to input from the keyboard 206. Fig. 6 (b)
The non-bright color table of No. 2 registers the layers 2 and 3 that are not highlighted, their gradation levels, and colors. The method of registering the gradation and the color may be the same as that of (a).

When the colors of (a) and (b) are the same in color, the gradation of (a) must be increased.
Even in the case of different colors, it is necessary to raise the brightness because it is from the viewpoint of highlighting, and it is necessary that the gradation degree of (a) is high.

In step 108, the graphic data and the attribute data of the corresponding layer are set to the specified color and the specified gradation level according to the instruction of the bright color table of FIG. 6 (a). In step 109, the graphic data and the attribute data of the corresponding layer are set to the prescribed color and the prescribed gradation degree in accordance with the instruction of the non-bright color table of FIG. 6 (b).

In the highlighting processing step 108, the data obtained in steps 108 and 109 is taken as display format data, and this is displayed on the display screen 205A of the CRT 205. As a result, the figures and characters of the layer 1 are highlighted, while the figures and characters of the layers 2 and 3 are not highlighted.

In the above-mentioned example, the hierarchy name column 104 is displayed on the screen, and the hierarchy to be highlighted is designated in this hierarchy name column 104. However, in a general facility drawing, the hierarchy can reach 300 layers. Therefore, it is not possible to list all the hierarchical names in the hierarchical name column. Therefore, the present invention makes it easier to select a hierarchy to be highlighted. Hereinafter, embodiments that characterize the present invention will be described.

In this embodiment, using the graphic file 112 and the hierarchy index table 107, rather than specifying the hierarchy in the hierarchy name field, the graphic displayed on the screen is specified, and the hierarchy is obtained from the graphic related to this specification. Highlight the hierarchy.

FIG. 5A shows an example of the graphic file 112, which is composed of graphic data 1, 2, 3, .... The graphic data 1 is a line graphic as shown in (b), and the graphic data 2 is a symbol graphic. The line figure shows a straight line figure in the facility drawing, and is composed of figure No., layer No., and coordinates of constituent points X1, Y2 ..., Xn, Yn. The symbol graphic consists of symbol information, graphic number, and center point. In addition to this, there are various graphic data formats.

On the other hand, the layer number in the graphic data of FIG. 5 is a layer number. Therefore, when the graphic data is edited centering on this hierarchy number, the hierarchy index table 107 as shown in FIG. 7 is obtained.

Therefore, in the hierarchy determining step 106, the graphic file 112 is searched by looking at the graphic pointed by the cursor to check which graphic in the file, and then the hierarchy index table 107 is searched to find the hierarchy to which this graphic belongs. . When the hierarchy to which the figure belongs is known, the bright color / non-bright color table 110 is created as described above. The subsequent processing is the same as that described above.

FIG. 8 shows an example of highlighting. (A) is an example of normal display without highlighting, and shows a state in which the cursor A indicates one hierarchy in the hierarchy display area 104. (B) shows an example of highlighting in the case where the cursor A indicates a water pipe figure.

When the screen is divided, the hierarchy to be emphasized may extend across multiple screens in the drawing configuration of FIG. At this time, by latching the bright color / non-bright color table 110, the highlighted hierarchy can be highlighted when another drawing is displayed even if only one screen is displayed.

The highlighting target may be only the graphic. After highlighting, there may be an example of color change or blinking display in addition to gradation enhancement.

〔The invention's effect〕

According to the present invention, since it is possible to easily select and highlight a hierarchy to be emphasized in a drawing to improve the visibility, the operability of the drawing management device is improved.
