Abstract

PURPOSE:To make an item entered on a facility drawing easy to observe by providing a means to identify and display a designated graphic with a related graphic simultaneously when an arbitrary graphic is designated on the drawing discriminatably from another. CONSTITUTION:At the time of displaying the facility drawing on the display drawing 101 of a display device and retrieving the corresponding detail information of the designated graphic by designating the arbitrary graphic on the facility drawing, a digital processor 201 designates one graphic (including attribute information) by a grouping file 112 which manages the connection of the corresponding graphic to a related graphic group, and simultaneously, performs identifying display such as color change or flicker display also with another related graphic. In such a way, it is possible to perform a graphic designation operation correctly by clearly discriminating the related graphic including the designated graphic from another series of graphic even in a congested graphic area part.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a drawing management device for converting facility drawings such as water and gas piping systems, electricity and telephone wiring systems into digital information and managing the drawings.

[Conventional technology]

Conventionally, the status of facilities such as water, gas, electricity, and telephone piping and wiring systems has been managed using drawings drawn on paper or polyester film. At this time, when changes occur to the facility, the drawings must be revised.All drawing correction work must be done manually, which requires a lot of labor and time, and there is a high rate of errors. have points. In order to solve this problem, it has been proposed to manage facility drawings by converting them into digital information, as described in, for example, Japanese Patent Publication No. 61-9667. To manage facility drawings by converting them into digital information, a large number of facility drawings (topographical maps, system diagrams, symbol diagrams, etc.) stored in a file device are displayed on a monitor on a display device.

In addition, drawing correction work is also performed by displaying the drawings on a display device.

[Problem to be solved by the invention]

In the above-mentioned conventional technology, when searching for a target figure from a facility drawing or searching for attribute information corresponding to the figure, the corresponding facility drawing is displayed on a monitor on a display device and the corresponding figure is designated. For example, when a user wants to know information about a water supply system in a certain house, the user specifies either the symbol of the water supply system, the corresponding room frame, or the hydrant No. 0 assigned to the water supply system to instruct a search for the relevant information. At this time, if the house is crowded, it is difficult to determine the correspondence between the corresponding room frame and the water supply system symbol position, so arrows or the like are sometimes drawn on the drawing to indicate the correspondence. However, this method has the problem that the number of items to be described on the facility drawing increases, making the dense drawing even more complicated and difficult to read.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and provide a drawing management device that, when an arbitrary figure is specified on the display screen of a display device, can simultaneously display the specified figure and its related figures in a manner that distinguishes them from others.

[Means to solve the problem]

The above purpose is to display a facility drawing on a display device, and when an arbitrary figure is specified on the drawing, the specified figure and the corresponding related figures are also distinguished by a function such as a color change or a flicker display so that they can be distinguished from each other. This is achieved by a drawing management device equipped with a digital processing device having a function of arbitrarily defining a group of related figures corresponding to each of the designated figures.

[For production]

The drawing management device displays a facility drawing on a display device, and when specifying an arbitrary figure on the facility drawing and searching for corresponding detailed information of the specified figure, the digital processing device searches for a group of figures related to the corresponding figure. Using the grouping file that manages joins, when one shape (including attribute information) is specified, other related shapes that have been specified for grooving are also identified by color change or flicker display. Even in the graphic area, related graphics including the designated graphic can be clearly distinguished from a series of other graphics, and graphic designation operations can be performed without error.

〔Example〕

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

FIG. 2 is an overall configuration diagram of a drawing management device which is an embodiment of the present invention. In FIG. 2, facility drawing data is stored in a file device (first storage means) 203. Facility drawing data includes graphic data such as topographic maps and pipeline maps, as well as town names and individual names related to the shapes.

There is attribute data expressed in characters and numbers such as pipe diameter and pipe type. The stored graphic data is input from a drawing input device @ 204 that scans drawings written on paper at regular intervals, converts them into gradations according to the shading of the read data, obtains digital images, and obtains coded data. . The facility drawing stored in the file device 203 is shown in Figure 3(a).
Consists of multiple drawings (1 to n) as shown in the drawing structure,
Each is divided into graphic data files (1 to n). Further, the graphic data is expressed in an orthogonal coordinate system as shown in the graphic coordinates in FIG. 3(b), and its length X0sYO in the X and Y axis directions is determined by the drawing size. These graphical data are shown in Figure 4 (
As shown in the hierarchical structure of b), the road 402 of layer 1, 2.3
．． Base frame 403. It has a data storage structure that is hierarchically separated from the conduit 404. Each layer of these data is superimposed as necessary to form graphic data 401 as shown in FIG. 4(a). On the other hand, attribute data is input to the file device 203 using a keyboard 206 or a data input device 208 such as a floppy disk that can input data in bulk.

The operator operates the mouse 207 to install the display!
In order to display a drawing on the (CRT) 205, the operator first operates the mouse 207 to move and designate the cursor CU to a certain function selection icon displayed on the CRT screen. When the “draw drawing” icon is specified, the central processing unit (CPU) 201 searches for the corresponding drawing data (graphic data and its attribute data) from the file device 203 and temporarily stores it in the main memory (second storage means) 202. . The main memory 202 functions to store programs for executing processes such as searching and editing screen data and data being processed. 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, and then displayed on the CRT 205. The operator can know the target drawing content from this display screen. In addition, to understand the finer details, enlarge the part and display it.

To do this, for example, the mouse 207 is used to move the cursor CU to designate an arbitrary rectangular area from the CRT display area at both ends on the diagonal line, and enlarge or reduce it to an arbitrary magnification. Specifically, a part of the relevant drawing data stored in the main memory 202 is edited to be enlarged or reduced via the CPU 201 and displayed on the CRT 205. Next, the desired drawing is searched from the file device 203 and the drawing data is CR after editing
T 205 and select any figure (
(including attribute data), and if there is a related figure to the specified figure, a method for displaying the related figure at the same time by changing colors or using flicker display in the same way as the specified figure will be explained with reference to Figure 1. .

FIG. 1 is a block diagram showing the main parts of an embodiment of the present invention, in which the CPU
201 is a diagram illustrating an example of a related graphic simultaneous display processing unit when an arbitrary graphic is specified in 201. FIG. In FIG. 1, a display surface 101 of a CRT 205 has an icon area 102 for mouse operation for selecting functions for searching and modifying a target drawing.
and a drawing display area 103 that displays drawings retrieved by mouse operation. The CPU 201 includes an operation input section 104, a one-figure search section 105, a specified figure search section 106, a grouping search section 107, an attribute search section 108, a one-display editing section 109, and a grouping figure setting section 115. The file device 203 includes a graphic file section 110, an attribute file section 111, and a grouping file section 112. With this configuration, the processing unit that specifies a target graphic corresponding to the attribute information to be searched for on the drawing display area 103 and simultaneously displays the graphic and related graphics performs the processing according to the following procedure.

Using the mouse 207 shown in FIG. 1 (FIG. 2).

The cursor CU, which moves in one-to-one correspondence with the operation of the mouse 207, is moved to the icon area 102 on the display surface 101 of the CPU 201, and the "drawing search" icon is selected and commanded. When this selection command is input to the operation input unit 104 of the CPU 201, the graphic search unit 10 of the CPU 201
Graphic file section 1 of file storage f1203 via 5
The corresponding drawing data is indexed from 10 and stored in the main memory 202.
Temporarily stored in . In the CPU 201, the display editing section 109
The drawing data is edited in accordance with the drawing display area 103 and displayed in the drawing display area 103. A case will be described in which the water supply device data of a certain house is searched from the display screen. The mouse 207 is operated to move the cursor CU onto the base frame 113, and when the cursor CU is on that line, the button on the mouse 207 is pressed to input the position coordinates of that point. The position coordinates are input to the specified figure search section 106 via the operation input section 104. The specified figure search unit 106 searches for the specified figure from the display screen data temporarily stored in the main memory 202. The grouping figure search setting unit 107 determines whether there is a figure related to the specified figure based on data indicating the relationship status between figures, which is stored in advance as the grouping file unit 112 on the file device 1203, and searches for related figures. (for example,
Water supply device 114. If there is a water tap, etc.), the main memory 202 is searched for the corresponding figure. The search results are sent to the display editing section 109, and the corresponding designated figure and related figures are simultaneously displayed in a different color or in a flicker manner on the drawing display area 103.

Further, for attribute information (for example, water supply device data) for a specified figure, the attribute search unit 10g searches the attribute file unit 111 for the corresponding attribute file, and the display editing unit 10
After editing in step 9, it is displayed in the drawing display area 103. On the other hand, a grooving file section 11 that manages relationships between figures.
2 is created by the grouping figure setting section 115.

The creation and search method will be explained below.

FIG. 5 is an explanatory diagram showing an example of a grouping operation of related figures. When the grouping figure setting unit 115 wants to group related figures as one unit, it first operates the mouse 207 to move the cursor CU over the first figure (base frame display 302 in FIG. 5), and then clicks the mouse 207 to Press the button to input the position coordinates of that point. The position coordinates are sent to the designated figure search unit 10 via the operation input unit 104.
6 specified figure search unit 106 inputted to main memory 2
02, the corresponding figure Nα corresponding to the specified position coordinates is indexed. The result is the group Nα in the index table 601 of the grouping file section 112 shown in FIG.
The drawings Ha and figure movements corresponding to the group Nα are stored in the grouping management table 602 having an index, a drawing h index, and a figure list index.

Next, specify the related shapes to be grouped. In the same manner as above, operate the mouse 207 to move the cursor CU over the next figure (the water supply device display 305 in FIG. Via 106.

Index the corresponding figure. The result is displayed in the grouping management table 602 in the drawing N of the corresponding data of the same group Nα.
α and figure Nα. Thereafter, related figures are designated and input in the same manner, and in order to speed up the search of the grouping management table 602, a B-tree structure, which is a known file indexing technique, is adopted. When searching for grouped figures, the grouping figure search unit 107 in FIG.
1, and the grouping Nn is searched from the drawing Na and figure size of the corresponding designated figure. When a figure Nα has the same grouping value, the corresponding figure island is searched from the figure file of the display drawing Nα which is temporarily stored in the main memory 202, and the color of the corresponding figure is changed or the figure is displayed with a flicker.

Since the related figures are grouped in this way, the corresponding attribute can be searched by specifying either one of the figures, for example, the base frame or the water supply device, when searching for figures or attributes. Further, even if it is difficult to identify the related figure, by specifying an arbitrary figure, the color of the related figure is changed or the related figure is displayed with a flicker, so that it can be easily identified without error. Examples of identification displays other than one color change or flicker display include line thickness and type (solid line,
(broken line, etc.) or hatching.

〔Effect of the invention〕

As explained above, the present invention allows you to arbitrarily define the relationship between displayed figures on a facility drawing, and if there is a figure related to a specified figure, the other can specify the corresponding attribute information by simply specifying the figure. Since you can search, change the color of the relevant figure, or display it in an identifying manner such as a flicker display, you can do it quickly and without mistakes even if you are not used to the operation.
