Description

[Detailed description of the invention]

0001

[Industrial Field of Application] The present invention relates to a drawing management device, in particular,
The present invention relates to a drawing management device that digitalizes and manages piping and wiring system diagrams for water, gas, electricity, telephone, etc., or drawings in which a system diagram and a map are superimposed.

0002

BACKGROUND OF THE INVENTION 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. On this occasion,
Any changes to the facility will require modifications to the drawings. All drawing correction work must be done manually, which requires a lot of effort and time, and there are problems in that there is a high rate of errors. In order to solve this problem, for example, as described in Japanese Patent Publication No. 61-9667, facility drawings are digitized and managed, and a large number of facility drawings (topographic maps, system maps, etc.) stored in a file device are Figures, symbol diagrams, etc.) are displayed on a display device to manage facility conditions. In addition, drawing correction work is also performed by displaying the drawings on a display device. Incidentally, pipe line data for water facilities in particular is hierarchically structured into water distribution pipes and water supply devices for each purpose, and each piece of data is expressed by vector information. This pipeline data is displayed on the display in any combination of hierarchies depending on the purpose. At this time, the display screen normally displays one drawing. However, in reality, pipe data on a map is connected continuously between drawings, so when searching for a single drawing on the display screen as in the past, it is difficult to search for adjacent states of pipe drawings and arbitrary positions. It has been difficult to grasp the interrelationships between the two accurately, in detail, and clearly. In other words, in the conventional technology, adjacent drawings are searched continuously, multiple drawings are displayed simultaneously, or
It has been difficult to respond to search requests such as indexing while moving over a wide area.

0003

[Problems to be Solved by the Invention] The present invention has been accomplished in response to the above-mentioned problems, and its purpose is to simultaneously display on the screen an index search section showing the adjacent status of facility management drawings. Therefore, it is an object of the present invention to provide a drawing management device that can continuously search for drawings at arbitrary positions or simultaneously search for a plurality of drawings from the search index section.

0004

[Means for Solving the Problems] The above object is to display an index search section for index searching adjacent position management data on a part of the display device in a facility drawing management system, and to display a target drawing in an adjacent relationship with the displayed drawing. This can be achieved by searching for a target drawing using the index search section, or by specifying the search for a plurality of target drawings at the same time.

[0005]

[Operation] Hierarchically structured pipeline data is digitized as vector information expressed by X and Y coordinate values, and the adjacent positional relationship of the pipeline data is managed on a drawing-by-drawing basis. Therefore, when displaying the relevant drawing of pipeline data on the display and continuously searching for drawings adjacent to the drawing, an index search drawing showing the adjacent positional relationship is displayed at the same time, and the target drawing is searched from the index search drawing. search for. Also, a search instruction for multiple drawings is specified at the same time. As a result, drawings can be processed continuously, and the positional relationship between drawings can be clearly determined.

The adjacent index diagram is edited as display data by the display editing section 110 and displayed on the index search section 111 on the display screen 101.

For example, facility pipeline drawings usually use 1/500 scale drawings for detailed facility management. FIG. 5 is a diagram showing the layout relationship of pipeline drawings corresponding to geographical positional relationships. In the case of a 1/500 scale map, a division divided into 25 vertically and horizontally is managed as one block, and these blocks are combined to form the entire block allocation. That is,
51 is the "01" block indicating one block of the pipeline drawing corresponding to the geographical positional relationship, and "01-" is divided into 25 blocks.
It consists of sections from ``01'' to ``01-25''. Similarly, 52 is block "02" of the pipe diagram corresponding to the geographical positional relationship, and is composed of sections "02-01" to "02-25". Block “1” of the pipeline diagram corresponding to the geographical positional relationship
1'', ``12'', . . . , ``21'', ``22'', . . . also consist of 25 sections. These blocks are then combined to form a block layout for the entire pipeline drawing. Therefore, drawings surrounding the currently displayed drawing can be searched based on the adjacency relationship between blocks and sections. A file in which this adjacency relationship is made into a table is the adjacency position management file 112 in the file device 203 of FIG. This adjacent position management file 112 manages the adjacent positional relationships of all the drawings in the management target area according to the drawing layout, and stores the drawing numbers showing the positional relationships as shown in FIG. is stored. The adjacent drawing management processing unit 106 searches this adjacent position management file 112 to find the corresponding drawing number. Adjacent drawings are determined and the results are passed to the index display processing unit 105.

[0013] Hereinafter, a detailed explanation will be given of a procedure for searching and displaying a relevant drawing and then successively searching for target drawings that are adjacent to this drawing. Display surface 10

Select and command an icon. In this case, the index search unit 111
, an adjacent position map divided into 16 parts centered on the corresponding display drawing is displayed. When two points are indicated on a diagonal line with the cursor CU in a block at an arbitrary position in this adjacent position map, the corresponding drawing in a rectangular area determined by the diagonal line is searched and displayed. An example is shown in FIG. In FIG. 7(a), “Drawing “01-13””
Four drawings 71, ``Drawing ``01-14'''', ``Drawing ``01-18'', and ``Drawing ``01-19'''', and adjacent position drawings 72 divided into 16 parts around these 4 drawings 71 are displayed. . In FIG. 7(a), when "01-07" and "01-13" in the adjacent position diagram 72 are indicated diagonally with the cursor CU, "01-07" and "01-13" surrounded by the diagonal area are shown in FIG. 7(b). -08'', ``01-12'', 4 drawings 73, ``Drawing ``01-07'''', ``Drawing ``01-13'''', ``Drawing ``01
-08'' and ``Drawing 01-12'' are displayed on the display surface 101, and the adjacent position map 74 of the index search section 111 also includes the four drawings ``01-07'' and ``01-08''.
, "01-12", and "01-13" are displayed adjacently.

FIG. 8 shows an example in which a continuous index search is performed by scrolling the contents of the index search section 111. Figure 8
When the cursor CU is pointed to the position "01-07" in (a), the entire adjacent position diagram 81 moves to the lower right, and as shown in the adjacent position diagram 82 in FIG. 8(b), it becomes "01-07".
07" to the center.

FIG. 9 shows an example in which indexed drawings are displayed on the index search section 111 so that a user can instruct a search for a desired drawing while visually checking the outline of the drawing contents. The mouse 207 is operated to move the cursor CU, and the "adjacent figure index superimposed display" icon in the icon area 102 is selected and commanded. In response to this selection command, the index search section 111 displays the index drawings of the relevant portion. Figure 9(a) is 4 drawings 91
“01-22” and “01-18” are displayed simultaneously.
When the drawing 92 is indicated diagonally with the cursor CU, the adjacent drawing 93 surrounded by the diagonal area is displayed on the display surface 101 as shown in FIG. Figure 94 also shows “01” in the 4th drawing.
-17", "01-18", "01-22", "01-
The display changes to an adjacent display with "23" as the center position.

[0017] In this way, the desired adjacent drawing can be searched for on the adjacent position map showing the adjacency relationship with the currently displayed drawing, thereby shortening the search operation time and speeding up and simplifying the continuous drawing search. can be achieved. Regarding the icon area 102, "drawing reading", "drawing search",
Although the cases of "attribute search", "adjacent figure display", "1 figure display", "4 figure display", and "adjacent figure index superimposed display" have been explained, it is possible to provide items for other searches. Needless to say.
