Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a drawing management device for converting facility drawings such as water and gas piping systems, electricity and telephone wiring systems into digital information and managing the drawings.

[Conventional technology]

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. In this case, when changes occur to the facility, it is necessary to revise the drawing, and all correction work for one drawing must be done manually, which requires a lot of labor and time, and there is a high rate of errors. have points. In order to solve this problem, it has been proposed to manage facility drawings by converting them into digital information, as described in Japanese Patent Publication No. 61-9667, for example. To manage facility drawings by converting them into digital information, a large number of facility drawings (topographical maps, system diagrams, symbol diagrams, etc.) stored in a file device are displayed on a monitor on a display device.

In addition, drawing correction work is also performed by displaying the drawings on a display device.

[Problems to be Solved by the Invention] In the above-mentioned conventional technology, when facility drawings are managed using digital information, it is possible to quickly search for and modify the desired facility drawings, thereby speeding up the target processing and improving operator operation. This is desirable. This facility drawing data has a data storage structure with separate layers, and its data capacity is large at over 100 kilobytes/drawing, and if you try to display it by data layer, the processing time of the central processing unit (CPU) will be consumed by the search time. Depending on the performance, it may take 30 seconds or more. In order to shorten this search time, there is a method of storing data in advance in a file device in a data format that can be immediately displayed on a display device. However, in this case, since the data section dedicated to display increases, the data capacity is required to be more than doubled, and there is a problem that the number of drawings that can be stored in the same file is halved. Furthermore, when the display screen is modified, it takes time and effort to modify the display-only data section again, resulting in a longer modification time.

SUMMARY OF THE INVENTION An object of the present invention is to provide a drawing management device that solves the above problems and allows facility drawings to be searched, displayed, and modified at high speed without increasing the amount of data in a file.

[Means to solve the problem]

The above purpose is to read out the corresponding divided facility drawing from the first storage means (file device) and read it out from the second storage means (file device) when displaying the divided facility drawing on the display device and modifying the drawing.
A figure index table that manages each figure storm in the corresponding divided facility drawing data created by editing the drawing data in hierarchical units from the divided facility drawing data stored in the main memory) and layer management of each figure. This is achieved by a drawing management apparatus equipped with a digital processing unit (CPU) that has the function of performing high-speed display of one drawing search and high-speed processing of drawing correction by temporarily storing the layer index table in the second storage means.

[Effect]

The drawing management device is configured such that when displaying a divided facility drawing on a display device and correcting the drawing, the digital processing device reads out the corresponding facility drawing from the first storage means and temporarily stores the divided facility drawing in the second storage means. Edit the corresponding figure data in hierarchical units from the drawing data, create a figure index table for managing each figure tooth in the corresponding facility drawing data, and a layer index table for layer management of each figure Nα, and store them in the second storage means. By temporarily storing facility drawings, it is possible to perform layer-by-layer search and display processing when searching for facility drawings and displaying them on a display device, thereby reducing search and display processing time, and correction processing when modifying displayed figures for each layer. In addition to saving time and speeding up operator operations, the first memory is used to create the figure index table and layer index table when reading the corresponding facility drawing from the first memory and temporarily storing it in the second memory. The amount of data in the means does not increase.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 is an overall configuration diagram of a drawing management device which is an embodiment of the present invention. In FIG. 2, facility drawing data is stored in a file device (first storage means) 203. Facility drawing data includes graphic data such as topographic maps and pipeline maps, as well as town names and two individual names related to the shapes.

There is also attribute data expressed in characters and numbers such as controlled caliber and pipe type. The stored graphic data is input from a drawing input device 204 that scans a drawing written on paper at regular intervals and converts it into gradations according to the shading of the read data to obtain a digital image and obtain coded data. The facility drawings stored in the file device 203 are composed of a plurality of drawings (1 to n), as shown in the drawing structure of FIG. 3(a), and each drawing is divided to create graphic data files (1 to n). Further, the graphic data is expressed in an orthogonal coordinate system as shown in the graphic coordinates of FIG. 3(b), and the lengths Xo and Yo in the x and y axis directions are determined by the drawing size. These graphical data are shown in Figure 4 (b
) As shown in the hierarchical structure of layers 1, 2, and 3, roads 402 and house frames 403. It has a data storage structure that is hierarchically separated from the conduit 404. Each layer of these data 402 to 404 is superimposed as necessary to form graphic data 401 as shown in FIG. 4(a). On the other hand, the attribute data is keyboard 2

Enter into 03.

In order for the operator to display a drawing on the display device (CRT) 205 by operating the mouse 207, the operator first operates the mouse 207 and moves the cursor CU to a function selection icon displayed on the CRT screen. and specify. [When the drawing reading J icon is specified, the central processing bag [(CPU) 201 searches for the corresponding drawing data (figure data and its attribute data) from the file device 203 and temporarily stores it in the main memory (second storage means) 202. The main memory 202 functions to store programs for executing processes such as searching and editing screen data and data being processed. The drawing data temporarily stored in the main memory 202 is edited by the CPU 201 in accordance with the effective display coordinates of the display area of the CRT 205, and then displayed on the CRT 205. The operator can know the target drawing content from this display screen. In addition, to understand the finer details, enlarge the part and display it. To do this, for example, the mouse 207 is used to move the cursor CU to designate an arbitrary rectangular area from the CRT display area at both ends on the diagonal line, and enlarge or reduce it to an arbitrary magnification.

Specifically, a part of the relevant drawing data stored in the main memory 202 is edited to be enlarged or reduced via the CPU 201 and displayed on the CRT 205. Next, the desired drawing is searched from the file device 203 and the drawing data is CRT after editing
A high-speed processing method for displaying on the screen 205 or modifying the displayed contents will be explained with reference to FIG.

FIG. 1 is a block diagram showing the main parts of an embodiment of the present invention, in which the CPU
2 is a diagram showing an example of an index table processing unit of 201. FIG. In FIG. 1, a display surface 101 of a CRT 205 includes an icon area 102 for mouse operation for selecting functions for searching and modifying a target drawing, and a drawing display area 103 for displaying drawings retrieved by mouse operation.
It is composed of.

The CPU 201 has an operation input section 104 and a figure search section 105.

It is composed of a figure index table 113 and a layer index table 114. The file device 203 includes a graphic file section 110 and an attribute file section 111. With this configuration, the index table processing section necessary for displaying or correcting the target facility drawing on the drawing display area 103 at high speed performs processing according to the following procedure.

Using the mouse 207 shown in FIG. 1 (FIG. 2),
The cursor CU, which moves in one-to-one correspondence with the operation of the mouse 207, is moved to the icon area 102 on the display surface 101 of 205, and the "drawing search" icon is selected and commanded. This selection command is sent to the operation input unit 10 of the CPU 201.
4, the graphic search unit 105 of the CPU 201 selects the file group! 203, the corresponding drawing data is indexed from the figure file section 110, and the figure data 1 of the main memory 202 is stored.
The zero-order index table creation unit 107 temporarily stores the graphic data 11 in the graphic data 12 in order to process graphic searches at high speed.
The figure editing unit 108 creates a figure index table 113 and a layer index table 114 from 2 and stores it in the main memory 202.The figure editing unit 108 edits the figure data 112 layer by layer using the figure index table 113 and layer index table 114. is sent to the display editing section 109.

The display editing unit 109 edits the drawing data according to the drawing display area 103 and displays it in the one drawing display area 103.

In addition, when modifying a displayed figure, the user operates the mouse 207 to move the cursor CU to the desired position and gives operational instructions such as adding, changing, or deleting the figure.

The position coordinates are input to the figure correction unit 106 via the operation input unit 104. The figure correction unit 106 modifies the figure data 112 on the main memory 202 and at the same time passes the corrected figure arrangement order to the index table creation unit 107. Then, the figure index table 113 and layer index table 114 corresponding to the corresponding figure arrangement Nα are corrected. Furthermore, when the correction is completed, the corresponding figure data 112
is stored in the graphic file section 110 of the file device 203.

Next, based on the calendar display management table 115, a layer pointer is created by intervening the layer pointer work 117 in method 1, and without intervening in method 2, and the layer index table 11
Create 4.

In this way, by searching for the corresponding graphic data and editing the graphic data layer by layer when displaying, high-speed display is possible. In addition, drawing corrections can be processed at high speed by drawing corrections using layer-by-layer editing data, allowing operators to perform operations quickly.

〔Effect of the invention〕

As explained above, according to the present invention, facility drawings can be displayed and modified at high speed without increasing the data capacity of the file, so that the operator can perform operations quickly.
