[Problem that the invention seeks to solve]

In the conventional drawing creation system as described above, the operator has to input all the existing drawings, which number several tens of thousands of sheets, directly by hand to obtain the symbol coordinates, which takes a lot of time and man-hours. There were problems such as.

This invention was made in order to solve this problem, and it is possible to automatically input information using an automatic drawing reading device, recognize necessary symbols and characters, and automatically associate coordinates with each other. The purpose of the present invention is to provide a figure creation system that creates equipment information including placement information, automatically draws equipment planes from topographic maps and plottable equipment information, and automatically synthesizes and outputs figures. .

[Means for solving problems]

The figure creation system according to the present invention provides a drawing creation system that creates a drawing in which equipment information is entered on a topographic map in which topographic information such as buildings and roads is entered. Then input equipment information such as the type of equipment and the connection relationship between equipment as another input information, save that input data, and then input the location of the equipment on the terrain as third input data. inputting equipment location information indicating whether the equipment is located, storing this input equipment location information, and associating the stored equipment information with the same equipment data in the equipment location information;
A graphic creation system is configured to integrate the two pieces of information, combine this integrated equipment information with the stored topographical information, and synthesize a drawing created from the equipment data on top of the topographical map. It is something.

[Effect]

In this invention, three types of input information are automatically input as system components of the computer mapping system, namely, topographical information, equipment information, and equipment location information.
Alternatively, input using manual input means, store each inputted information in memory as a file, and arbitrarily extract each figure information to be drawn on the display from the file and create a synthesized figure. Create drawings.

[Implemented]

FIG. 1 is a block diagram of a drawing production system showing an embodiment of the present invention. In FIG. 2, the same parts as in FIG. , an image reader for reading topographic maps or a digitizer for inputting topographic map data; 8 is a topographic information file that is a means for storing input information; 9 is a means for inputting equipment layout information, that is, an equipment layout information input device; ,
The example of the present invention includes an equipment layout diagram reading device 10 and an equipment layout diagram recognition device 11. 12 is a means for storing equipment layout information; an equipment layout information file; 13, data from the equipment information file 4 and equipment layout information file 1;
An equipment data matching device 14 is a means for associating the information from 2, and 14 is a means for synthesizing equipment information including topographical information and layout information, that is, a graphic synthesis device.

Next, the operation will be explained. The topographic map is input using the topographic information input device T and stored in the topographic information file 8. For example, when an image reader is used as the terrain information input device 7, image information is stored. Further, the type and connection relationship of each piece of equipment are inputted from the equipment information input device 3. For example, by inputting that data from the keyboard? l) Symbols of equipment as illustrated in Figure 2,
Line types, connection relationships, etc. are input and stored in the equipment information file 4. Next, the equipment location information is input to the equipment layout information input device 9, and in this example, a topographic map on which equipment information is manually entered is input to the equipment layout map reading device 10. Here, an image obtained by directly reading a diagram with an image reader is input, and this image data is transferred to the equipment layout diagram recognition device 1.
1, information processing is performed to detect symbols in the diagram, recognize their types and positions, and obtain arrangement information.

For example, in cases such as 'WJ2 diagrams (a), (b), (cl), this is done by detecting the △ mark, O mark, ・0 mark, and patterns in the figure by pattern matching.
The recognized symbol information is stored in the equipment layout information file 12. Next, the equipment data matching device 13 associates the equipment information stored in the equipment information file 4 with the equipment layout information stored in the equipment layout information file 12 to obtain equipment information having the layout information. For example, this process involves superimposing the recognized equipment information on a topographic map with equipment information filled in and displaying it on a display, and then having a human instruct the recognized equipment data and adding it to the equipment information file. This is done by inputting the equipment information number (written in the diagram) using a doublet or keyboard and making the correspondence. Through this operation, the recognized placement information is added to the equipment information.

Finally, the equipment information including the layout information and the topographic map information are synthesized by the figure synthesizer 14. This work involves generating figures such as symbols, line characters, etc. for equipment information and writing them on the topographic map image.

In addition, although the above example shows an example in which equipment is manually associated with its equipment layout, equipment information written on a topographic map is inputted by automatic recognition, and depending on where this equipment information is written, , it is also possible to determine whether or not the symbol is attached to a nearby equipment symbol, and to automatically associate the equipment with the equipment layout information and automatically recognize and obtain all the equipment information including the layout information based on the drawing. In this case, the facility information is recognized by a method such as cutting out characters from a drawing as an isolated area of a specific size and performing character recognition by pattern matching or the like.

In addition, when the equipment information to be stored in the equipment information file 4 already exists, the effect of the drawing creation system of the present invention is significant. The equipment information input device 3 is an MT (magnetic tape) device or the like.
