Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drawing management apparatus for converting facility drawings such as water and gas piping systems and electricity, telephone wiring systems, mechanical drawings, printed circuit board mounting drawings, and various design drawings into digital information for management. Regarding

[0002]

2. Description of the Related Art Conventionally, the drawings for drawing the situation and the design drawings for facilities and equipment are drawn on paper or polyester film. At this time, if there is a change in facilities or equipment,
You need to modify the drawing. Drawing correction work is
All of them have to be done manually, which requires a lot of labor and time, and has a problem in that the rate of erroneous writing is high. In order to solve this problem, for example, as described in JP-A-63-254565, facility drawings are electronically managed and managed, and a large number of facility drawings (topographic maps and system diagrams) stored in a file device are managed. , Symbol drawings, etc.) are displayed on the display device of the drawing management device on the monitor for correction work. By the way, at present, when digitizing drawing information, there are a vector information method of storing drawing coordinates as drawing information and drawing information as a raster information method of storing drawing information as a set of points.

[0003]

When digitizing and managing drawing information, there are the following two problems. First, when a drawing is managed as vector information, new creation and correction work can be easily performed with a mouse or tablet, and the quality of the drawing is less deteriorated by the correction, but the more information there is, the longer the initial input takes. Next, when managing drawings with raster information, it is suitable for existing drawing management with a low correction frequency, and digitization of drawings is simple and immediate from the reading device, but errors during reading are large. However, correcting the raster information directly is time-consuming and inaccurate. In addition, the amount of data becomes larger than that of vector information. The present invention has been made in consideration of the above points, and its purpose is to be able to handle raster information and vector information, utilize the advantages of both, and to create accurate drawings easily and in a short time,
An object of the present invention is to provide a drawing management apparatus that can be modified, saves space, and quickly retrieves stored drawings.

[0004]

[Means for Solving the Problems] A drawing input system for converting input raster drawing information into vector information, and raster data and vector data are hierarchically classified regardless of the data type, displayed in superposition, and displayed as a vector. It has a drawing management system that corrects data, digitizes drawing information as raster data, converts only the area to be modified into a vector, and modifies this vector data. This is accomplished by storing the information as raster data and fast searching this raster data.

[0005]

[Function] Since the drawing information is input as raster information,
You can easily enter the drawing. Further, since only the modified portion of the drawing is vector-converted and corrected, the minimum vectorization is required, and the conversion time is short. Since the storage is done by an optical disk, it is possible to manage a large capacity drawing in the library device, and by reusing the existing drawing, it is possible to create a new drawing or modify a drawing in a short time with less labor. It is possible to reduce the rate of the above error.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 2 is a basic configuration diagram of a drawing management apparatus according to an embodiment of the present invention. In FIG. 2, the drawing management device is a drawing management system 21 including a drawing input system 201, a drawing reading device 202, and a central processing unit (CPU).
1, file device 212, drawing output device 213, mouse 214, main memory 215, display 216, keyboard 217, optical disk filing system 22
1 and a library device 222. here,
The drawing data stored in the file device 212 includes raster data in which floor plans and construction completion drawings are stored as point information, vector data in which coordinate information is stored, and each graphic and each vector data. There is history data corresponding to the raster data file, and attribute data expressed by characters and numbers such as other related information. The drawing data is read by scanning a drawing written on a paper by scanning the drawing reading device 202 at regular intervals, converting the data into gradations and gradations according to the gradation and the gradation of the data, digitalizing the data, and inputting it as raster data. The drawing data read by the drawing reading device 202 is subjected to coordinate code conversion by the drawing input system 201 as necessary, and converted into vector data.
The drawing data of raster data or vector data input from the drawing input system 201 is transferred to the file device 212 by the central processing unit (CPU) 211, and each data file is created. The raster data and the vector data are shown in an orthogonal coordinate system as shown in FIG. 4A, and the lengths X ₀ and Y ₀ in the X and Y axis directions are determined by the drawing size. Further, the drawing data based on the raster data and the vector data has a hierarchical structure as shown in FIG. The vector data is layered for each figure type, and the raster data is layered for each data file. Colors are assigned to the respective layers, and the layers are displayed on the display device (CRT) 216 in an overlapping manner. The CRT 216 includes, for example, the drawing 23 shown in FIG.
6 is displayed. On the other hand, the attribute data is the keyboard 217.

The cursor CU is moved to the icon for function selection displayed on the RT screen. When the icon of "drawing drawing" is designated, the CPU 211 retrieves the corresponding drawing data (raster data, vector data and its attribute data) from the file device 212 and temporarily stores it in the main memory 215. The main memory 215 stores a program for executing processing such as search and edit of screen data and data being processed. The drawing data temporarily stored in the main memory 215 is displayed on the CRT 216 after being edited by the CPU 211 according to the effective display coordinates which are the display area of the CRT 216. The operator can know the target drawing content from this display screen.

Incidentally, in order to grasp a fine portion, the portion is enlarged and displayed. For this purpose, for example, the cursor CU is moved by the mouse 214, a rectangular arbitrary area is designated from both ends on the diagonal line from the CRT display area, and the area is enlarged or reduced to an arbitrary magnification. Specifically, the main memory 21

The image is enlarged / reduced through 1 and displayed on the CRT 216. In the enlargement / reduction editing, while the button of the mouse 214 is being pressed, a part of the corresponding drawing data stored in the main memory 215 is repeatedly enlarged / reduced by the CPU 211, and the cursor is continuously enlarged or reduced on the CRT 216. The coordinates in the CRT display area indicated by the CU are centered and freely changed to any magnification. When you want to see the drawing outside the CRT display area, while the button of the mouse 214 is being pressed, the coordinates indicated by the cursor CU are repeatedly moved to the center of the CRT display area for continuous scrolling, and the target portion is displayed on the CRT. Display in the area. This is because a part of the coordinates of the corresponding drawing data stored in the main memory 215 is changed by the CPU 211 according to the difference between the coordinates of the center of the CRT display area and the coordinates in the CRT display area indicated by the cursor CU and is displayed on the CRT 216. The drawing portion repeats the movement by the deviation.

The drawing data stored in the file device 212 and the drawing data temporarily stored in the main memory 215 are printed out on a paper or polyester film by the drawing output device 213. The optical disk filing system 221 has registered therein drawing data stored in the file device 212 for long-term storage and backup and drawing data temporarily stored in the main memory 215. The optical disk filing system 221 has a consistent number (search key) for searching the library device 222.
Allocate each drawing and register drawing data. This search key is stored in the file device 212 as one of the attribute data. In order to read the drawing data registered in the library device 222 and display it on the CRT 216, first, the search key of the target drawing data is searched from the attribute data of the file device 212, and this search key is searched by the CPU.

Transmit to. The optical disk filing system 221 uses the search key to obtain target drawing data from the library device 2
22 and transmits to the CPU 211. CPU21
1 temporarily stores the transmitted drawing data in the main memory 215, edits the data as necessary, and then the CRT 2
16 is displayed.

Next, a process of changing a part of the drawing input by the raster data into vector data will be described. FIG. 1 is a configuration diagram showing details of an embodiment of the present invention, which will be described with reference to the operation flow of FIG. In FIG. 1, the display surface of the CRT 216 is composed of a mouse operation icon area 226 for selecting a function for searching and modifying a target drawing, and a drawing display area 236 for displaying the drawing searched by the mouse operation. There is. In order to display the drawing read by the drawing reading device 202 in the drawing display area 236 of the CRT 216, the mouse 214 is operated to display C
The cursor CU is moved to the icon area 226 on the RT display surface, and the "drawing input" icon is selected and instructed. here,
For drawing input, a method of displaying the drawing read by the drawing reading device 202 as raster data in the drawing display area 236 on the display surface of the CRT 216, and converting the raster data into vector data by the drawing input system 201 and displaying the drawing There is a method of displaying in the area 236, which is used properly according to the purpose. The latter method takes time to convert to vector data, and the former method cannot be expected to have high accuracy. Here, the former method will be described below. The “drawing input” selection command is sent to the drawing management control unit 112 via the operation input unit 114. The drawing management control unit 112
When the drawing input command is input, the drawing input command is sent to the drawing input system 201 via the information transmission processing unit 113,
The drawing reading device 202 is operated to execute a process of reading a handwritten drawing (step S101 in FIG. 5). The raster drawing data read by the drawing reading device 202 is transmitted from the drawing input system 201 to the drawing management control unit 112 via the information transmission processing unit 113. The drawing management control unit 112 temporarily stores the raster drawing data in the main memory 215, and sends the drawing data stored in the main memory 215 to the drawing management display processing unit 110. The drawing management display processing unit 110 edits drawing data in accordance with the drawing display area 236, and the drawing display area 236 of the CRT 216.
The raster data drawing information is displayed on (S104).
On the other hand, when the drawing data (raster data) is stored in the library device 222 of the optical disk filing system 221, the cursor CU is moved and the "read optical disk" icon is selected and instructed. This selection command is sent from the operation input unit 114 to the drawing management control unit 112. The drawing management control unit 112 searches for a search key candidate from the attribute database 133 of the file device 212, temporarily stores it in the main memory 215, and then sends the search key candidate data to the drawing management display processing unit 110. The drawing management display processing unit 110 displays the search key candidates in the drawing display area 236 of the CRT 216 based on the input search key candidate data. The operator inputs the target search key using the keyboard 217 or moves the cursor CU to the position of the search key candidate being displayed by using the mouse 214,

The designated search key is sent to the optical disk filing system 221 via the operation input unit 114 and further from the drawing management control unit 112 via the information transfer processing unit 115. The filing system 221 searches for the target drawing data from the library device 222 based on the search key and transmits it to the drawing management control unit 112. The drawing management control unit 112 temporarily stores the raster data of the searched drawing in the main memory 215 (S103), and sends the drawing data stored in the main memory 215 to the drawing management display processing unit 110. The drawing management display processing unit 110 edits the drawing data according to the drawing display area 236, and C
The raster data drawing information is displayed in the drawing display area 236 of the RT 216 (S104). In this way, the raster drawing information read from the drawing reading device 202 or the raster drawing information taken out from the library device 222 is displayed on the CRT 216.

Next, a case where a part of this drawing is modified will be described. First, in order to change to vector data, the cursor CU is moved to the icon area 226 on the CRT display surface using the mouse 214, and "partial vectorization" is performed.
Select and order the icon. The operation input unit 114 receives this selection command and transmits it to the drawing management control unit 112. When the drawing management control unit 112 inputs a partial vectorization command,
The arbitrary area vectorization processing 116 is activated. Then CR
The corrected portion of the drawing displayed in the drawing display area 236 of T216 is displayed by the cursor CU using the mouse 214.
It is designated as a rectangular area as shown by the thick frame in FIG. The operation input unit 114 transmits the instructed coordinate value of the rectangular area to the arbitrary area vectorization processing unit 116 via the drawing management control unit 112. Of the raster drawing information stored in the main memory 215, the arbitrary area vectorization processing unit 116 designates an arbitrary area from the orthogonal coordinate system drawing data as shown in FIG. 4B, and the coordinates (X ₁ , Y ₁ )
A process of extracting drawing data only inside (X ₁ , Y ₂ ) (X ₂ , Y ₁ ) (X ₂ , Y ₂ ) is executed (S105). The extracted figure data (raster data) of the corrected portion is taken in by the drawing management control unit 112, and the information transfer processing unit 113.

The modification of the modified partial vector drawing data stored in 15 is permitted. For the operator data, the cursor CU is moved to the screen display area 236 using the mouse 214 to move, add, or delete the endpoints or constituent points of the vector drawing data and the entire vector data graphic (S108). The modified vector drawing data and raster drawing data are stored in the vector database 131 and the raster database 132 of the file device 203 by the drawing management control unit 112, respectively. A search key is assigned to the drawing data that is not changed for a long period of time, and is automatically stored in the attribute data 133 of the file device 212 together with the correction history, the correction date, and the time. Here, in order to register the graphic data obtained by converting a part of the raster drawing data read by the drawing reading device 202 into vector drawing data in the optical disk filing system 221, first, the drawing management control unit 112.
Sends the raster day drawing information to the information transfer processing unit 115. At this time, the vector data is converted into raster data by the vector raster conversion processing unit 117 and combined with the raster data drawing information (S109). The converted information transfer processing unit 115 sends the data to the optical disk filing system 221, and the optical disk filing system 221 stores the raster data drawing information in the library device (S110).
