Description

DETAILED DESCRIPTION OF THE INVENTION (Field of the Invention) The present invention relates to a method for storing, searching and displaying one or more drawings containing a large amount of information, such as maps and blueprints.

(Prior art) Conventionally, this type of method stores a large number of drawings one by one independently on a computer magnetic disk, etc.
Data corresponding to a desired drawing is searched and displayed based on the numbers assigned to each drawing. Therefore, if the desired part of the drawing is near the center of the drawing and the display range of the screen displaying the search results is sufficiently wide, the correspondence between the desired part and its vicinity can be recognized, so there is no problem. However, if the desired part is near the edge of the drawing, it will be displayed near the edge on the display screen, so even if the display range is wide enough, it is difficult to manipulate the relative relationship between the desired part and the vicinity related to other drawings. The problem was that it was difficult for people to recognize it. Furthermore, since the drawings are searched and displayed as units, the amount of information increases, resulting in problems such as increased search time, decoding time, display time, etc.

(Objective of the Invention) In order to solve these problems, the present invention divides an input drawing into a plurality of blocks in relation to each other's positions without duplication, and searches the drawing information and each block for each block. For example, when displaying a block, use the correspondence table to search for the corresponding block from the search information and display it near the center of the display screen. At the same time, the blocks surrounding the block are also displayed at the same time.This will be explained in detail below with reference to the drawings.

(Structure and operation of the invention) FIG. 1 is a diagram showing the relationship between drawings to be input and blocks in the present invention, where 1 indicates an input drawing;
(i, j) is the i-th block in the horizontal direction and the j-th block in the vertical direction when the drawing is divided into blocks. The input drawing may be divided into blocks after the drawing is input, or whether the input drawing is physically larger than the size of the drawing handled by a normal input device.
If there are extremely minute characters drawn and it is difficult to input them directly, you can divide the drawing to be input into multiple blocks in advance and enlarge them as necessary before inputting them. good.

In this way, each drawing is divided into blocks without duplication within or between drawings, and the connection relationships between blocks are made clear from the connection relationships within and between drawings. In this way, a large number of drawings become one drawing connected as block units, and for example, the block adjacent to the left of block (i, j) is block (i-1, j). The interconnection relationship between blocks can be easily calculated during a search.

Figure 2 is a diagram that shows the correspondence between each block and the search information; for example, when a map is used as an input drawing, the search information includes addresses, building names, etc., and the input drawings include mechanical design drawings. When using , the search information includes component names, part names, etc. Using this correspondence table, the corresponding block number can be obtained from the search information.

FIG. 3 is a conceptual diagram of the present invention, and 2 shows a display screen used to display search results. When displaying the block (i, j) obtained from the correspondence table in FIG. Block {(i-1, j-1),
(i, j-1), etc.) are displayed simultaneously. That is, the size of the block described in Fig. 1 is set smaller than the number of pixels constituting the display screen as shown in Fig. 3, and the corresponding block is displayed near the center of the display screen, and the surrounding blocks are also displayed. To display on a display screen while maintaining the positional relationship with the corresponding block. This provides an advantage in that the operator can recognize the corresponding block while making it correspond to the drawing in its vicinity.

Here, as the periphery of block (i, j),
Although the case where the upper, lower, left, right, and diagonal blocks are displayed is shown, it goes without saying that the outside of the block may be further displayed within an appropriate range on the display screen if necessary.

FIG. 4 is a block diagram showing the configuration of an embodiment of the present invention, in which 3 is an input section, 4 is an information storage section, 5 is a conversion section, 6 is an arithmetic section, 7 is a reading section, and 8 is a display memory section. , 9 is a display control section, and 10 is a display section.

The input unit 3 is a part for inputting attribute information as drawing information and search information, and is a workstation that can handle drawings and includes, for example, a facsimile, a keyboard, a display, a processing unit, etc. The search information is divided and input into a plurality of blocks without duplication by relating their positions to each other, and a correspondence table between the search information and each block is created as described in FIG. The information storage section 4 is a section that stores drawing information in units of blocks inputted from the input section 3, and is composed of, for example, a magnetic disk device and a control section. The conversion unit 5 has a correspondence table input from the input unit 3 and obtains a desired block number from the given search information, and the obtained block number is processed in the calculation unit 6.
The peripheral block numbers required for the display described in FIG. 3 are calculated and provided to the reading section 7. Reading section 7
obtains the corresponding drawing information from the information storage section 4 using the given block number and writes it into the display memory section 8, and the display control section 9 reads out all or a part of the display memory section 8 and displays it on the display section 10. give a signal. As a result, a drawing including a block corresponding to the given search information is displayed on the display unit 10. At that time, what to display from among the drawing information of the corresponding block stored in the information storage section 4 may be specified at the time of inputting the search information, or the display control section 9
You can also select.

FIG. 5 is an explanatory diagram of another embodiment of the present invention, for example, for explaining the case where multiple types of drawings with different scales are handled.

The purpose of this is to help the operator easily recognize the relative position of the desired search object from the display screen, even if the display range of the display screen with respect to the original drawing (hereinafter referred to as drawing A) is very small. That is. In other words, drawings with a large scale (hereinafter referred to as B
It's called a drawing. ) Information is added and stored in the information storage section 4, and as shown in FIG. 5, the added block of drawing B information covers a range where a plurality of blocks of drawing A are collected.

For example, if n×n (=n ² ) blocks in drawing A are made to correspond to drawing B, the relationship between the block (i', j') in drawing B and the block (i, j) in drawing A can be seen from FIG. (i', j') = ([i/n], [j/n]) However, [ ] is a Gaussian symbol.

You will be able to get it with Therefore, if the block (i, j) of the corresponding drawing A is found from the search information, and the block (i', j') of the drawing B is also obtained by the calculation unit 6, the block (i, j) of the corresponding drawing You can display the relevant parts of drawings A and B. In this case, the display memory section 8, display control section 9, and display section 10 may be displayed simultaneously as two types of configurations corresponding to each drawing, or as only one type of configuration corresponding to more complex drawings. They may be displayed alternately.

Although FIG. 5 has been described using drawings with different scales, the same scale with different descriptions is also effective in understanding the relative relationships between pieces of information. In that case, the relationship between the blocks is (i', j') = (i, j).

The basic system of the present invention has been explained above, but
The application will be described below.

[First application] In the explanation of Fig. 2, the attribute information of specific drawings contained in blocks, such as addresses and building names, was used as search information. In this case, it also handles abstract attribute information of the drawing, such as whether the block includes a reference point such as a station, and for example, if at least one block has important abstract attribute information in the display block obtained by the calculation unit 6. Check whether it is included,
If it is not included, the arithmetic expression of the arithmetic unit 6 is changed so that the block containing important abstract attribute information is always displayed. Specifically, the method for determining the block to be displayed was described in the explanation of FIG. Make it. For example, when the block corresponding to the search information is (i, j), the surrounding blocks are usually (i-1, j-1), (i, j
-1), (i+1, j-1), (i-1, j), (i+
1, j), (i-1, j+1), (i, j+1), (i
+1, j+1), but if there is no important abstract attribute information, select further outer blocks, such as (i-2, j-2), (i-1, j-2), (i,
j-2) etc. By changing the function of the arithmetic unit 6 in this manner, the searched block is displayed in association with surrounding important blocks.

[Second Application] This concerns the shape of blocks in drawings.

In the explanation of FIGS. 1 and 3, it has been described that the drawings are simply divided into a plurality of blocks for storage and display. The shape is the same as or close to the shape of the pixel configuration. That is, the number of display pixels of the display section 10 is generally set to be the same as or smaller than the number of displayable pixels of the display memory, that is, the display memory section 8, but the shape of the block depends on the memory configuration of the display memory section 8. If the shape is similar to the shape of the pixel configuration of the display section 10, drawing information can be written by effectively utilizing the memory without creating a vacant space or shortage in the display memory section 8. Also, if the shape is similar to the shape of the pixel configuration of the display section 10, the display This provides the advantage that blocks to be displayed are displayed correctly without being displayed in the middle or with blank spaces at the corners of the screen.

[Third application] This relates to the method of displaying drawings.

Up until now, we have been talking about dividing the drawing information into blocks and displaying the input screen as is. If the information is displayed in a different shape, for example in a different color, it will be easier for the operator to identify it. Furthermore, when displaying a plurality of drawings at the same time, it is effective to provide color information for each drawing, perform logical operations between drawings, etc. from the viewpoint of the operator's drawing recognition.

(Effects) As explained above, the present invention divides a drawing into a plurality of blocks in relation to each other's positions without duplication, and provides drawing information and search information for searching each block for each block. When searching and displaying a correspondence table, the corresponding block or its surrounding blocks are displayed using the corresponding table from the search information. This provides the advantage of being able to recognize while understanding the positional relationships. Further, since drawings can be handled in units of blocks, advantages such as shortening of search time, decoding time, and display time, and ease of drawing correction can be obtained.
