Abstract

PURPOSE:To easily and quickly select part of a facility map and, at the same time, to prevent display confirmation omission and correction omission by designating the part by dividing the facility map into meshes. CONSTITUTION:A mesh display 104 is provided so that a facility map can be displayed in a state where the map is divided into regular meshes and the map can be enlarged at every mesh when the map is displayed on a display device 101. Therefore, the facility map can be displayed in a state where the map is enlarged to a fixed magnification without designating the enlarging area of the map and, at the same time, since each area divided by the meshes can be displayed without overlapping and omission, the whole area of the facility map can easily be recognized successively. Moreover, since the enlarging magnification can be set to an easily seeable scale, wrong reading of each area can be prevented.

Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention is applicable to water and gas piping systems, electricity, and more! ! The present invention relates to a drawing management device that converts and manages facility drawings such as wiring systems into digital information.

[Conventional technology]

BACKGROUND ART Conventionally, the status of facilities such as water, gas, electricity, pipes, piping systems, etc. has been managed using drawings drawn on paper or polyester film. At this time, if changes occur to the facility, the drawings will need to be revised. All drawing correction work must be done manually, which is problematic in that it requires a lot of effort and time, and the rate of errors is high. In order to solve this problem, it has been proposed to manage facility drawings by converting them into digital information, as described in Japanese Patent Publication No. 61-9667, for example. 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]

By the way, when facility drawings are converted into digital information and managed, the facility drawings are stored in a file device, and when necessary, the desired facility drawings are retrieved from the file device and displayed on the display device6. In order to display large facility drawings on a display device and read detailed drawing information, the target area must be enlarged to a size that is readable by humans. The enlarging operation is performed by enclosing an arbitrary rectangular area, or by specifying the target figure to be enlarged and enlarging it to a constant magnification. However, when checking the entire area of the displayed facility drawing in detail one after another, the above method specifies a rectangular area each time an enlargement operation is performed, so that area specification is likely to be omitted. Furthermore, if an enlargement operation is performed so as to partially overlap the previously designated area in order to prevent omissions, there is a problem in that the number of enlargement operations increases.

The present invention has been made in response to the above-mentioned problems, and its purpose is to provide a drawing management device that facilitates the operation of enlarging the entire area of facility drawings and facilitates drawing management.

[Means to solve the problem]

According to the present invention, when displaying a divided facility drawing on a display device, the displayed divided facility drawing is divided into meshes at regular intervals so that enlargement can be performed in mesh units.

[Effect]

Display divided facility drawings expand the area into mesh-divided units. As a result, the enlarged area of the facility drawing can be displayed at a constant magnification without specifying the enlarged area, and the enlarged display can be performed without overlapping with other areas or omitting display areas. therefore,
It becomes easy to sequentially check the entire area of facility drawings, and operations can be performed easily. In addition, the mesh division unit is variable,
It can be enlarged to a size that is easy for the operator to see, eliminating the possibility of misreading.

〔Example〕

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

FIG. 2 is a basic configuration diagram of a drawing management device which is an embodiment of the present invention.

Second, the file device 203 stores facility drawing data. Facility drawing data includes graphic data such as topographic maps and pipeline maps, and attribute data expressed in characters and numbers, such as town names, personal names, management diameters, and pipe types related to the graphics. The stored graphic data is input from a drawing input device 204 that scans a drawing written on paper at regular intervals and converts it into gradations according to the shading of the read data to obtain a digital image and obtain coded data. Facility drawings are in the third
Figure 3 (a) consists of multiple drawings, each of which is divided to create a figure data file. The figure data is shown in an orthogonal coordinate system as shown in figure 3 (b), and its X and Y axis directions are determined by the drawing size. The lengths Xo and Yo are determined. These figure data are the fourth
As shown in Figures (b) to (d), the data storage structure is hierarchically divided into roads, base frames, and pipelines. Each layer of these data is superimposed as necessary to form graphic data as shown in FIG. 4(a). On the other hand, the attribute data is stored on the keyboard 206.
Alternatively, use the file device 203 using a data input device 208 such as a floppy disk that can input data in bulk.
Enter. In order for an operator to display a drawing on the display device (CRT) 205 by operating the mouse 207, the operator first operates the mouse 207 to move the cursor CU to a function selection icon displayed on the CRT screen.
Move and specify. When the “read drawing” icon is designated, the central processing unit (CPU) 201 searches the file device 203 for the corresponding drawing data (graphic data and its attribute data) and temporarily stores it in the main memory 202 . The main memory 202 functions to store programs for executing processing such as screen data retrieval and editing, as well as 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 in the display area of the CRT 205, and then transferred to the CRT.
205. The operator can know the target drawing content from this display screen. Incidentally, the CRT display area shown in FIG. 5(b) is often smaller than the original size of the input drawing shown in FIG. 5(c) compared to FIG. 5(a). In order to understand the fine details, parts are enlarged and displayed as shown in FIG. 5(c). For this, mouse 207
Move the cursor CU and display the CRT in Figure 5(b).
Specify an arbitrary rectangular area from the display area at both diagonal ends and enlarge or reduce it to an arbitrary magnification. Specifically, a part of the corresponding drawing data stored in the main memory 202 is enlarged/reduced via the CPU 201 and then displayed on the CRT 205.
to be displayed.

Next, the enlargement operation for searching the file device 203 for the target drawing, editing the drawing data, displaying it on the CRT, and enlarging the area of the displayed drawing to a readable size is shown in FIG. explain.
