Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a drawing management device that digitalizes and manages facility drawings such as water and gas piping systems, electric and telephone wiring systems, and the like.

[Conventional technology]

Conventionally, the status of facilities such as water, gas, electricity, telephone, piping, and wiring systems has been managed using drawings drawn on paper or polyester film. At this time, if changes occur to the facility, the drawings will need to be revised. Drawing correction work generally has to be done manually, which requires a lot of effort and time, and has the problem of a high rate of errors. In order to solve this problem, it has been proposed to manage facility drawings by converting them into digital information, as described in, for example, Japanese Unexamined Patent Publication No. 63-254565. 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 display device on a monitor. In addition, drawing correction work is also performed by displaying the drawings on a display device.

[Problem to be solved by the invention]

When managing facility drawings as digital information in this way,
It is possible to create drawings for pipeline construction using these facility drawings. However, the scope of pipeline construction often spans a different area from the drawing section, which is the management unit of facility drawings, that is, multiple drawing sections, and it is necessary to arbitrarily cut out the necessary area from multiple drawings. . Therefore, it is important to extract topographical parts from a plurality of drawings, and a process is required to further write pipeline figures on these cut-out figures. In addition, the construction cost estimation process that calculates the construction cost identifies the material items, number of materials, and man-hours required to bury the relevant pipe underground, and performs the cost estimation process for each item. However, the number of items is large, over 100, and there are changes after the aggregation process, which can cause discrepancies between the construction drawings and the construction cost estimate, and the construction cost estimation process becomes complicated.
The problem is that the amount of work is large.

The present invention has been made in response to the above-mentioned problems, and its purpose is to provide a drawing management device that can integrally process construction drawings and construction cost estimates from digitized facility drawings.

[Means for solving the problem] The above purpose is to display arbitrary construction drawings by displaying them next to each other, extracting a necessary arbitrary area from them, and specifying the extraction of one-layer data. is created. In addition, if you enter the section of the pipeline to be laid out when creating a construction pipeline, pipeline symbols that are defined in advance for each pipeline type are automatically laid out, and the number of symbols for each symbol type is automatically tallied. It is possible to achieve integrated processing of construction drawings and construction estimates at the time of updating.

[Effect]

Drawings of multiple facilities to be constructed are displayed as adjacent drawings, and arbitrary areas are cut out from the displayed drawings and arbitrary hierarchical data is extracted. This cut-out area drawing is transferred according to the size of the construction drawing to determine the layout. Furthermore, the pipeline, which is construction data, is written on this drawing. Next, by inputting 2 pipe materials, 2 diameters, and 2 sections, the type of number of pipes required is automatically extracted, and the corresponding pipe symbol is automatically selected from the pipe symbols defined in advance for each pipe type. Automatically paste in the corresponding position. By aggregating the number of conduit symbols and the attribute data corresponding to the symbols for each symbol type, the construction cost estimation items and number of people can be determined, and the construction drawings and construction cost estimates can be integrated as industrial cost estimation data. .

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 2 is a basic 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 203. Facility drawing data includes graphic data such as topographic maps and pipeline maps, and attribute data expressed in characters and numbers, such as town names, personal names, management diameters, and pipe types related to the graphics. 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. As shown in FIG. 3(a), the facility drawing consists of a plurality of drawings, each of which is divided into graphic data files. The graphic data is shown in Figure 2 (b
) is shown in a rectangular coordinate system, and the drawing size is
The lengths X O and Y o in the Y-axis direction are determined. These graphic data have a data storage structure in which roads, house frames, and pipes are hierarchically separated, as shown in FIGS. 4(b) to 4(d). These data are superimposed on each layer as necessary as shown in Figure 4 (a).
) as graphic data. On the other hand, attribute data is input to the file device 203 using a keyboard 206 or a data input device 208 such as a floppy disk that can input data in bulk. 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 drawing" icon is specified, the central processing unit (CPU) 201 searches the file device 203 for the corresponding drawing data (graphic data and its attribute data) and temporarily stores it in the main memory 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, use the mouse 207 to move the cursor CU.
is moved 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 corresponding drawing data stored in the main memory 202 is edited to be enlarged or reduced through the CPU 201 and displayed on the CRT 205.

Next, search for the drawings for construction from file @203,
After editing the drawing data, display it on the CRT 205, cut out the construction target area from the display screen and use it as construction topographic data, create a construction pipeline on the topographic data, and enter data on the diameter and pipe type. We will explain the integrated processing of construction drawing creation and construction cost estimation, in which the pipe type symbol of the corresponding pipe is automatically selected and placed, and the cost estimation items and number of items for construction cost estimation are automatically totaled.
