Abstract

PURPOSE:To display the block concerned or its peripheral block by using a correspondence table from retrieval information, in case of a retrieval display, by dividing a drawing into plural blocks so as to be related to each other, and accumulating in advance the correspondence table to the retrieval information. CONSTITUTION:An input part 3 inputs a drawing and attribute information, the drawing is not overlapped but divided and inputted into plural blocks so that its mutual position is related, and a correspondence table of retrieval information and each block is generated. The inputted drawing information of a block unit is accumulated in an information accumulating part 4. A converting part 5 has the correspondence table inputted from the input part 3, obtains a desired block number from the given retrieval information, calculates the peripheral block number required for a display by an operating part 6 and gives it to a readout part 7. The readout part 7 obtains the drawing information concerned from the accumulating part 4 by using the given block number, and writes it in a display memory 8. A display control part 9 reads out the whole or a part of the memory 8, and a display part 10 displays the drawing containing the block corresponding to the given retrieval information.

Description

[Detailed Description of the Invention] (Field to which the invention pertains) The present invention relates to
The present invention relates to a method of accumulating the above drawings and searching and displaying them.

(Prior art) Conventionally, this type of method stores a large number of drawings one by one independently on computer magnetic disks, etc., and then retrieves data corresponding to a desired drawing from the numbers assigned to each drawing. It was designed to be searched and displayed. 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 also be displayed near the edge on the display screen, so even if one display range is sufficiently wide, 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 one drawing is searched and displayed as a unit, the amount of information increases, resulting in problems such as an increase in 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 by relating their positions to each other without duplication, and searches the drawing information and each block for each block. For example, a table of correspondences with component names of drawings is stored, and when displaying, search for the corresponding block from the search information using the table of correspondences, 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 a drawing to be input and a block in the present invention, where 1 is an input drawing, and byj) is the j-th horizontal direction when the drawing is divided into blocks. This is the j-th block in the vertical direction. The input drawing may be divided into blocks after the drawing is input, or if the input drawing is physically larger than the size of the drawing handled by a normal input device or contains very fine characters, etc. If it is difficult to input them directly, the drawing to be inputted may be divided into a plurality of blocks in advance and enlarged as necessary before being inputted.

In this way, each drawing is divided into blocks without duplication within or between drawings, and the connection relationships between blocks are clarified from the connection relationships within and between drawings. In this way, even a large number of drawings will become one drawing in which blocks are connected as units.
The block adjacent to the left of j) is block (i-1,j
), the interconnection relationships 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, that is, a correspondence table. 1 For example, when a map is used as an input drawing, the search information includes address, building base, etc., and the input drawing includes a mechanical design drawing. When using , the search information includes component names, part names, etc. The corresponding block number can be obtained from the search information using this correspondence table.

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 of FIG.

The surrounding blocks H1-Lj-LL (ipj-1, etc.) are displayed at the same time. That is,
The size of the block described in FIG. 1 is set smaller than the number of constituent pixels of the display screen, as shown in FIG.

Moreover, the corresponding block is displayed near the center of the display screen, and surrounding blocks are also displayed on the display screen while maintaining their 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, a case is shown in which blocks above, below, left, right, and diagonally are displayed as the periphery of block (i, j), but if necessary, an appropriate range outside the block may be displayed on the display screen. Needless to say.

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 unit;
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 is composed of, for example, a facsimile, a keyboard, a display, a processing unit, etc., and as described in FIG. The search information is divided into a plurality of blocks and inputted 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.The obtained block number is displayed in the calculation unit 6 as shown in FIG. Necessary peripheral block numbers are calculated and provided to the continuation unit 7. The reading unit 7 uses the given block number to obtain the corresponding drawing information from the information storage unit 4 and writes it into the display memory unit 8, and the display control unit 9 reads out all or a part of the display memory unit 8.
A display signal is given to the display unit 10. As a result, the display section 10
displays a drawing containing blocks corresponding to the given search information. At this time, what to display 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 may be selected by the display control section 9.

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 make it easier for the operator to 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 one original drawing (hereinafter referred to as the drawing) is very small. That is. That is, information on drawings with a large scale (hereinafter referred to as 8 drawings) is added to the information storage section 4 so that the ratio of the drawings displayed on the screen to the entire drawings stored in the information storage section 4 is increased. As shown in FIG. 5, the added eight drawing information blocks cover a range in which a plurality of drawing blocks are collected.

For example, if nXn (=n") blocks of drawing A correspond to 8 drawings, blocks Cx' of 8 drawings from FIG.
The relationship between the block (i, j) in the drawing and the block (i, j) is (i'', j')・([-], [-L])n
n However, [] is a Gauss symbol.

You will be able to get it with Therefore, if the corresponding drawing block (i, j) is obtained from the search information and the block (1'tj') of the 8 drawings is obtained in the calculation unit 6, the information stored in the information storage unit 4 in advance can be saved. It is possible to display the corresponding parts of drawings A and 8. In this case, the display memory section 81, display control section 9, and display section 10 may be displayed simultaneously as two types of configurations corresponding to each drawing, or may be alternately displayed as only one type of configuration corresponding to more complex drawings. may be displayed.

In Fig. 5, explanation was made using drawings with different scale ratios, but
Even if the description contents are different at the same scale, it is effective for understanding the relative relationships between the information. In that case, the relationship between the blocks is (i'yj') = (L j).

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

[First application] In the explanation of FIG. 2, address is used as search information.

The importance of the block was explained using the attribute information of the specific drawing contained in the building name answer block.

For example, in the case of a map, abstract attribute information of the drawing, such as whether the block includes a reference point such as a station, is also handled, and the display block obtained by the calculation unit 6 is given an abstract attribute that is important to at least one block. It is checked whether or not abstract attribute information is included, and if it is not included, the arithmetic expression of the arithmetic unit 6 is changed so that blocks containing important abstract attribute information are 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-t
L(itj-tL(i+1tj-iL(i-x+j)p
(iit ,j)j (i-1yj”lL (itj
+iL (i+1.j+1), but if there is no important abstract attribute information, select a further outer block, for example (+-2, j-2) y(i-itj-zL(itj
-z) etc. will be displayed. By changing the function of the calculation unit 6 in this manner, the searched block is displayed in association with surrounding important blocks.

[Second application] This concerns the shape of the blocks in the drawing.

In the explanation of FIGS. 1 and 3, it was stated that the drawings are simply divided into multiple blocks and stored and displayed.
The shape of the block is the same as or close to the memory configuration of the display memory section 8 or the pixel configuration of the display section 10. 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 is determined by 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 causing any empty space or shortage in the display memory section 8. Also, if the shape is the same as the shape of the pixel configuration of the display section 10, the display This has the advantage that blocks that should be displayed are displayed correctly without being displayed in the middle or with empty spaces at the corners of the screen.

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

So far, we have described how to display input drawings as they are while dividing drawing information into blocks. 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. Further, when displaying a plurality of drawings at the same time, it is effective to provide color information for each drawing and perform logical operations between the 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 order of mutual positional relationship without duplication, and performs a search for drawing information and each block for each block. A correspondence table with information etc. is accumulated, and when searching and displaying, the corresponding block or the block and surrounding blocks are displayed using the correspondence table from Search Information Power 1, so you can find the corresponding location in the target drawing. This has the advantage of being able to recognize objects while understanding their surrounding positional relationships. Further, since drawings can be handled in units of blocks, advantages such as shortened search time, decoding time, and display time, and ease of drawing correction can be obtained.
