Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a drawing file management system, and in particular, divides a map of an arbitrary region into a plurality of regions, and stores map information of each region as drawing data. The present invention relates to a drawing file management method suitable for storing and managing each drawing file.

[Conventional technology]

Conventionally, when managing piping systems such as gas and water, maps with piping system diagrams drawn on them 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 performed. However, when a change occurs in the system, it is necessary to change the drawings, but conventionally all drawing changes have been done manually, resulting in the problem of requiring a lot of effort and time. It was hot.

Therefore, the entire system such as piping was divided into small areas as described in the Japanese Patent Publication No. 61-96675.
The system diagram information, map information, position coordinate information, etc. of each area are stored in the file section as drawing data, and the various information stored in the file section is displayed together with the drawing on the screen of the monitor display device, and the key input section Modify the drawing on the screen through operations,
A method has been proposed in which corrected drawing information is stored in a file section and drawing information for each area is stored in the 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 from within a file section, such as when creating a new map by combining multiple files, it takes time to identify the file that meets the specifications. This is not enough to reduce search time.
Incidentally, as a method for displaying map information as an image, those described in Japanese Patent Application Laid-Open No. 59-174714, Japanese Patent Application Laid-Open No. 56-17641, and Japanese Patent Application Laid-Open No. 17460-1982 are known. Even if these methods are simply applied, information regarding the distribution of drawing files according to specifications, such as the presence or absence of drawing files, cannot be immediately retrieved.

SUMMARY OF THE INVENTION An object of the present invention is to provide a drawing file management system that allows instant retrieval of information regarding the distribution of drawing files according to specifications.

[Means for solving problems]

In order to achieve the above object, the present invention divides a map of an arbitrary area into a plurality of areas, stores map information of each area as drawing data in the main memory for each drawing file, and stores an index of each drawing file. Specification data related to the management of drawing files is attached to the TSx data as alternative data, and each specification data is stored in the auxiliary memory as bitmap data in which each area on the map and the storage area are associated with each other. In response to a command to extract a drawing file according to specifications from a group of drawing files in an area, the bit map data in the auxiliary memory corresponding to the specified area is searched, and the drawing files are managed according to the search results. This system adopts a drawing file management method that is characterized by the following. moreover,
The present invention divides a map of an arbitrary region into a plurality of blocks, divides each block into a plurality of areas, stores the map information of each area as drawing data in the main memory in each drawing file, and Specification data related to drawing file management is attached to the index data of the drawing file as alternative data, and each specification data is converted into directory data in which the location of each block on the map and storage area are associated. In response to a command to store drawing files in the auxiliary memory and extract drawing files according to specifications from a group of drawing files in the specified area, search the directory data in the auxiliary memory corresponding to the specified area, and follow the search results. This method employs a drawing file management method that is characterized by managing drawing files.

[Effect]

When searching the bit map data in the auxiliary memory to obtain information about the distribution of drawing files according to the specifications, this auxiliary memory contains each region and storage area on the map as specification data that can be selected between the two. Since the associated bit map data or directory data associated with each block on the map and the storage area is stored in advance, the auxiliary memory can be searched without searching the main memory where the image data is stored. By simply doing this, you can immediately obtain information regarding the distribution of drawing files according to the specifications.

〔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 for each area as drawing data. The drawing data included in this map information includes piping,
Includes system diagram data such as wiring, map image data, location data, etc. Further, as shown in FIG. 2, when the map 10 is divided into 85×50 areas, map information for 4250 areas is stored as drawing data in drawing files F1 to F4250. Each drawing file in the drawing file group F is accessed by commands from the central processing unit (not shown), and the data of each drawing file is displayed on the CRT screen in response to operations from the key operation section. It's getting old.

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

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

File type 2: A drawing file with a scale of 1/500, which is aligned 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 aligned so that adjacent drawing files are connected.

File type 5: A drawing file with a scale of 1/500 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. A file type 1 drawing file is used in a step prior to the alignment process. In addition, detailed map information is stored in 1/500 scale drawing files, and it takes a lot of time to input these drawing files. 2500 drawing files at scale 1/500
1/500 scale drawing files are input in sequence.

Drawing file group F is file management data section 14
The file management data section 14 is composed of a plurality of bitmap data sections 16 and a directory data section 18.

The bitmap data section 16 contains each drawing file F.
It has index data of 1 to Fn, and usage data related to the management of drawing files is attached to this index data. For example, if the map 10 shown in Figure 2 is divided into 4250 areas and data indicating the presence or absence of a drawing file is used as data (“1” indicates the existence of a drawing file, “0” indicates that there is no drawing file). ”), the index data of the drawing file included in area 10A will be ”
1" is assigned. The index data of the drawing file included in the area 10B is assigned "0" data. These data are stored in the bitmap data section 16.
When storing in , as shown in Figure 3,
They are sequentially stored in an area 16A of auxiliary memory different from the disk memory (main memory). In this case, the bitmap data of the map 10 consists of 4250 bits of data, as shown in FIG. The index data is stored over 133 rows (row 0 to row 132). For example, if the lower left area of map 10 is 1 and the lower right area is 50, then area 1 to area 32
data is stored in line 132, and the data from area 33 to area
50 data is stored in the 131st line. Thereafter, data for each area is stored in order in the same manner. That is, each piece of data is stored in association with the position on the map 10. Therefore, when an arbitrary area on the map 10 is specified and the bitmap area corresponding to this area is searched, data regarding the presence or absence of a drawing file for the specified area can be instantly searched.

Also, when using data indicating whether a drawing file has been created as specification data ("1" indicates that a drawing file has been created, and "0" indicates that a drawing file has not been created). , it is possible to create bitmap data indicating whether or not a drawing file has been created. At this time, the bitmap data section 16 is also processed using the same method as the bitmap data that indicates the presence or absence of a drawing file.
is stored in

The directory data section 18 stores each drawing file F1.
It has index data of ~Fn, and each index data is attached with directory data that specifies the position on the map. For example, as shown in FIG.
It is divided into 0206, 0301 to 0306, and 0401 to 0406, and directory data specifying each area is attached to the file group included in each area. For the drawing file group included in area 0101, 0101 is added as direct data to the index data of each drawing file.
Attach the data. In addition, map 10 is 15× in the vertical direction.
It is divided into 5 areas + 5 areas, and the horizontal direction is divided into 15 x 3 areas + 10 areas, so area 0101 has 15
x15=225 drawing files are included.

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 bit map that indicates the presence or absence of a 1/500 scale drawing file.

2 A bit map that indicates whether a drawing file with a scale of 1/500 has been created.

3. Directory data of the created drawing file with a scale of 1/500.

Data item 4 for managing drawing files of file type 2 A bit map that indicates whether a drawing file with scale 1/500 with figure alignment completed has been created.

5 Directory data of 1/500 scale figure-aligned drawing file.

Data item for managing file type 3 face files.

6 A bit map that indicates the presence or absence of a drawing file with a scale of 1/2500.

7 Bitmap indicating whether or not a 1/2500 scale figure file has been created.

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

Data item for managing drawing files of file type 4.

9 Bitmap indicating whether or not a drawing file with scale 1/2500 figure alignment has been created.

10 Directory data of a drawing file with a scale of 1/2500 that has been aligned.

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

Data item for managing drawing files of file type 5.

12 A bit map that shows whether a drawing file exists for a drawing divided from a scale of 1/2500.

13 Drawing file directory data regarding drawings divided from scale 1/2500.

The data of these data items 1 to 13 are bitmap data section 16 and directory data section 1, respectively.
It is stored in 8. And file management data section 1
The data stored in 4 is the target file detection unit 20.
It is now being detected by 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 detects the index 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 index data 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 on the map 10, along with the operator's operation,
Setting information for displaying an image of a specific area from the key operation unit (for example, information indicating a specific area, search command information such as whether or not a drawing file with a scale of 1/500 has been created or whether a drawing file has been created) When input, index data of an area corresponding to a specific area in the bitmap data section 16 is searched. The search results are displayed on the CRT screen as the distribution of required drawing files.
Therefore, the operator can immediately know whether a necessary drawing file exists or whether a drawing file has been created.

As described above, according to this embodiment, the index data of the bitmap data section 16 is searched to determine the presence or absence of drawing files, etc., without sequentially searching the data in the disk memory constituting the drawing file group. Since information about the distribution of drawing files according to the specifications is obtained, information about the distribution of drawing files according to the specifications can be searched at high speed. Therefore, unnecessary searches can be omitted even when displaying a specific drawing from a plurality of drawing files.

On the other hand, along with the operator's operation, setting information for displaying a specific area image from the key operation unit (for example, information indicating a specific area, search command for a created drawing file among drawing files with a scale of 1/500) information) is input, the directory data section 18
Index data of an area corresponding to a specific area is searched. The search results are displayed on the CRT screen as the distribution of required drawing files.

In this case, the 85 x 40 area on the map 10 is divided into 24 groups, and the directory data is used to specify the areas belonging to each group, so the amount of data is smaller than when specifying the location on the map using bit map data. Therefore, the location on the map can be specified. Therefore, drawing files can be efficiently accessed according to specifications even with a small data capacity.

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

〔Effect of the invention〕

According to the present invention, bitmap data in which each area on the map is associated with a storage area is stored in advance in an auxiliary memory different from the main memory that stores drawing file data, as specification data to choose from. Since the bit map data in the auxiliary memory is searched at the time of search to obtain information regarding the distribution of drawing files according to the specifications, the search speed can be increased. In addition, in an auxiliary memory different from the main memory that stores drawing file data, direct data in which each block on the map is associated with a storage area is stored in advance as specification data to assist in searching. Information about the distribution of drawing files according to specifications is obtained by searching memory directory data, which speeds up the search and allows efficient access to drawing files according to specifications even with a small data capacity. can.
