Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a drawing file management method, and particularly relates to a drawing file management method.

The present invention relates to a drawing file management method suitable for dividing a map of an arbitrary region into a plurality of regions, storing map information of each region as drawing data in each drawing file, and managing the drawing files.

[Conventional technology]

Conventionally, when managing piping systems such as gas and water, maps with piping system diagrams drawn on the map have been used. According to this drawing, the piping system in each region can be immediately understood, and work such as installing new piping or changing the system can be easily carried out. However, when a change occurs in the system, it is necessary to change the drawings, but conventionally all drawing changes have been done manually, which has the problem of requiring a lot of effort and time. Ta.

Therefore, as described in Japanese Patent Publication No. 61-96675, the entire system such as piping is divided into small areas, and the system diagram information, map information, position coordinate information, etc. of each area are stored in the file section as drawing data. , displays various information stored in the file section together with the drawing on the screen of the monitor display device, corrects the drawing on the screen by operating the key human power section, and stores the corrected drawing information in the file section. A system has been proposed that stores drawing information for each area in a file. According to this method, work to change the system drawing can be done quickly.

[Problem that the invention seeks to solve]

However, with conventional methods, when searching for a specific file in the file section, such as when creating a new map by combining multiple files, it takes time to identify the file that meets the specifications. It was not enough to shorten the search time.

The present invention has been made in view of the above-mentioned conventional problems, and its purpose is to provide a drawing file management system that can immediately identify drawing files that meet specifications.

[Means for solving the problem] In order to achieve the above object, the present invention divides a map of an arbitrary region into a plurality of areas, and stores district information of each area as drawing data in each drawing file. , to the index data of each drawing file.

The drawing file management method, which includes specification data related to the management of drawing files and manages drawing files by searching index data, has also been developed.Furthermore, the map of any region can be divided into multiple areas, and each Map information of each area is stored as drawing data in each drawing file,
This is a drawing file management system in which directory data for specifying a position on a map is attached to the index data of each drawing file, and the drawing files are managed by searching the index data.

[Effect]

In order to identify a drawing file according to specifications, index data of each drawing file is first searched, and the drawing files are managed based on the specification data attached to the index data. Furthermore, in order to specify a plurality of drawing files according to specifications, the index data of each drawing file is searched, and the drawing files are managed based on the directory data to which the index data is attached.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows the main configuration of an embodiment to which the present invention is applied. In FIG. 1, a drawing file group F is composed of a plurality of drawing files F1 to Fn. Each of the drawing files F1 to Fn is composed of, for example, a disk memory, and divides a map of an arbitrary region into a plurality of areas, and stores map information of each area as drawing data. The drawing data included in this map information is piping.

As shown in Figure 2, if the map 10 is divided into 85 x 50 areas, the map information of 4250 areas will be stored as drawing data. Drawing edges F1 to F4
250.

Each drawing file of the drawing file group F is accessed by a command from the central processing unit (not shown), and the data of each drawing file is accessed in accordance with the operation from the key operation unit.
It is displayed on the RT screen.

Further, the drawing file group F is classified into the following five types.

File type 1: Drawing file with a scale of 11,500.

File type 2: A drawing file with a scale of 11,500, which has been subjected to alignment processing so that adjacent drawing files are connected.

File type 3: Drawing file with a scale of 1/2500.

File type 4: A drawing file with a scale of 1/2500, which has been subjected to matching processing so that adjacent drawing files are connected.

File type 5: A drawing file with a scale of 11,500 created by enlarging the drawing file of file type 4 above five times.

Of these five file types, the drawing file of file type 2 is ultimately used. One drawing file of file type is used in a step before matching processing. Also, detailed map information is stored in a drawing file with a scale of 11,500, and it takes a lot of time to input this drawing file, so in order to start up the system quickly, it is recommended to A drawing file is input as a substitute for the 11,500-scale drawing file Tsutsutsubakizaka, and then highly accurate 11,500-scale drawing files are sequentially input.

The drawing file group F is connected to a file management data section 14, and the file management data section 14 is connected to a plurality of bitmap data sections 16. It is composed of a directory data section 18.

The bitmap data section 16 contains each drawing file F1 to Fn.
For example, if the map 10 shown in Fig. 2 is divided into 4250 areas, the specification data regarding the existence of drawing files is attached to this index data. When data indicating the presence/absence of the drawing file is used (if the drawing file is present, PA1 is set, and if there is no drawing file, it is set to "0"), area 10A is used.
The index data of the drawing file included in
'' is added to the index data of the drawing file included in the area 10B. When storing these data in the bitmap data section 16, as shown in FIG. The bitmap data of the map 10 is sequentially stored in the area 16A, and is composed of 4250 bits of data as shown in FIG. Therefore, the index data of map 10 is 133
Stored across rows.

In addition, data indicating whether or not one drawing file has been created as specification data (ti 171 when a drawing file has been created)
and when the drawing file is not created, it is On.
It is also possible to create bitmap data that indicates whether or not one drawing file has been created. At this time, the data is stored in the bitmap data section 16 in the same manner as bitmap data indicating the presence or absence of a drawing file.

The directory data section 18 has index data for each of the drawing files F1 to Fn, and each index data is attached with directory data that specifies the position on the map. For example, as shown in Figure 5, map 10 is area 0.
101~0106゜0201~0206,0301~0
306° It is divided into 0401 to 0406, and the directory data that specifies each area is attached to each file 2 included in each area.The drawing file group included in area 0101 has directory data attached to the index data of each drawing file. The data of olol is attached as . Note that the map 10 is divided into 15×5 areas+5 areas in the horizontal direction and 15×3 areas+10 areas in the vertical direction, so the area 0101 includes 15×15=225 drawing files.

When managing the drawing file group F using file types 1 to 5, the file management data section 14 can be configured as follows.

Data item for managing drawing files of file type 1.

1. A bitmap indicating the presence or absence of a drawing file with a scale of 11,500.

2. Bitmap indicating whether a drawing file with a scale of 11,500 has been created.

3. Directory data of created drawing file with scale 11500.

Data item for managing drawing files of file type 2.

4. A bitmap indicating whether or not a figure-aligned drawing file with a scale of 11,500 has been created.

5. Directory data for figure-aligned drawing files with a scale of 11,500 6 Data items for managing drawing files of file type 3.

6. Bitmap indicating the presence or absence of a drawing file with a scale of 1/2500.

7. Bitmap indicating whether a graphic file with a scale of 1/2500 has been created.

8. Directory data of a drawing file with a scale of 1/2500.

Data item for managing drawing files of file type 4.

9. Bitmap 610 indicating whether or not a drawing file with scale 1/2500 figure alignment has been created, scale 1/25
Directory data of 00 figure-aligned drawing file.

11. Bitmap indicating whether a divided scale drawing file of 1/2500 has been created.

Data item for managing drawing files of file type 5.

12.Scale 1. A bitmap indicating whether a drawing file exists for a drawing divided from /2500.

13. Directory data of drawing files related to drawings divided from scale 1/2500.

The data of these data items 1 to 13 are stored in a bitmap data section 16 and a directory data section 18, respectively. The data stored in the file management data section 14 is detected by the target file detection section 20. That is, the target file detection section 20 is composed of a bitmap data detection section 22 and a directory data detection section 24, and each detection section reads the index data of the bitmap data section 16 and the directory data section 18 according to instructions from the central processing unit. It is configured to search and detect data attached to index data. The contents of the index data detected by each detection section are sequentially transmitted to the central processing unit as drawing file management information.

In the above configuration, when displaying an image of a specific area of the map 10, by searching the index data of the bitmap data section 16, it is possible to immediately determine whether a required drawing file exists or whether a drawing has been created. This allows unnecessary searches to be omitted, such as when displaying a specific drawing from multiple drawing files. or,
By searching the index data in the directory data section 18, the position of each drawing file on the map 10 can be specified, and drawing files can be accessed efficiently even with a small data capacity.

This embodiment can also be applied to a distributed database. In this case, the existence of a drawing file managed in another region as bitmap data is set to 1"', and the drawing files below that are set to "0". It is also possible to display

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to immediately select a drawing file according to specifications from one drawing file group by searching index data, which speeds up the search and also enables drawing files to be saved even with a small data capacity. can be accessed efficiently.
