Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a drawing management apparatus for digitally managing facility drawings such as water and gas piping systems, electricity and telephone wiring systems, and the like.

[Conventional technology]

2. Description of the Related Art Conventionally, situation management of facilities such as water supply, gas, electricity, piping such as telephones, and wiring systems has been performed using drawings drawn on paper or polyester film. At this time, if a change occurs in the facility, it is necessary to correct the drawing. The work of correcting the drawing must be performed manually, which requires much labor and time, and has a problem that the error rate is high. To solve this problem,
For example, as disclosed in Japanese Patent Application Laid-Open No. 63-254565, it has been proposed to manage facility drawings by converting them into digital information. In order to manage and convert facility drawings into digital information, a large number of facility drawings (topographic maps, system maps, symbol maps, etc.) stored in a file device are displayed on a display device on a monitor. Also, the work of correcting the drawing is displayed on the display device.

[Problems to be solved by the invention]

The pipeline data of a water supply facility is hierarchically structured into a water distribution pipe and a water supply device for each use, and each data is represented by vector information. The pipeline data is displayed on the display in any combination of layers according to the purpose. The display screen superimposes and displays the respective layers, and is suitable for grasping the positional relationship of the pipelines on the topographic map and the like. Pipeline data is subject to frequent changes, relocations and removals of the pipeline, and drawings are revised each time. When the revision history of the pipeline data is assigned to a specific hierarchy and the secular change is grasped on the display, the same figure often overlaps the same place. It is difficult to do.

The present invention has been made in view of the above points, and an object thereof is to provide a facility drawing composed of graphic data obtained by superimposing hierarchical data separated into a plurality of hierarchies and attribute data indicating attributes of the graphic data. It is an object of the present invention to provide a drawing management apparatus capable of displaying a plurality of hierarchical data in an arbitrary hierarchy on the same screen of a display device in a time series.

[Means for solving the problem]

The above object is to select one hierarchy to be stereoscopically displayed from graphic data obtained by superimposing hierarchical data separated into a plurality of hierarchies, and to display a plurality of the hierarchical data in a time series on the same screen of the display device. It is achieved by making it.

[Action]

The hierarchical data separated into hierarchical levels are digitized as vector information expressed by X and Y coordinate values. The data can be freely compressed, expanded, reduced, rotated, etc. by applying coordinate transformation.

In addition, when a plurality of arbitrary one layer data is displayed three-dimensionally in a time series on the same screen of the display device, the layer data in a certain layer can be viewed in a time series. The history can be grasped on one screen.

〔Example〕

 Hereinafter, an embodiment of the present invention will be described 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, facility drawing data is stored in a file device 203. The facility drawing data includes graphic data such as a topographic map and a pipeline map, and attribute data expressed by characters and numerical values such as a town name, a personal name, a pipe diameter, and a pipe type related to the graphic. The stored graphic data is input from a screen input device 204 that scans a drawing drawn on paper at regular intervals, converts the read data into light and shade gradations in accordance with the light and dark, and obtains a digital image to obtain coded data. The facility drawing is composed of a plurality of drawings as shown in FIG. 3 (a), and each is divided to create a graphic data file. The graphic data is shown in a rectangular coordinate system as shown in FIG.
The lengths X ₀ and Y ₀ in the X and Y axis directions are determined. These graphic data have a data storage structure that is hierarchically separated from roads, house frames, and pipelines as shown in FIGS. 4 (b) to 4 (d). These data are superimposed on each layer as necessary to form graphic data as shown in FIG. 4 (a). On the other hand, the attribute data is
The data is input to the file device 203 using a data input device 208 capable of inputting data collectively such as 6 or a floppy disk. In order for the operator to operate the mouse 207 to display a drawing on the digital device (CRT) 205, the operator first operates the mouse 207 to move the cursor CU to the function selection icon displayed on the CRT screen. To specify.
When the "draw drawing" icon is designated, the central processing unit (CPU) 201 retrieves the corresponding drawing data (graphic data and its attribute data) from the file device 203, and searches the main memory.
Temporarily store in 202. The main memory 202 functions to store a program for executing processing such as search and editing of screen data and data being processed. The drawing data temporarily stored in the main memory 202 is displayed on the CRT 205 after being edited by the CPU 201 in accordance with the effective display coordinates which are the display area of the CRT 205. The operator can know the contents of the target drawing from the front screen. In order to grasp a detailed part, the part is enlarged and displayed. To do this, for example, move the cursor CU using the mouse
An arbitrary rectangular area from the display area is designated at both ends on a diagonal line and enlarged or reduced to an arbitrary magnification. Specifically, a part of the relevant drawing data stored in the main memory 202 is replaced with C
The image is enlarged / reduced via the PU 201 and displayed on the CRT 205.

Next, a coordinate conversion method for layer-separating whether or not the digitized pipeline drawing changes for each layer and displaying the separation result in a hierarchical three-dimensional manner will be described.

FIG. 1 shows a main part of an embodiment of the present invention.
FIG. 8 is a diagram showing an example of a coordinate conversion process of hierarchical stereoscopic display in FIG.

In FIG. 1, a display surface 101 includes a mouse operation icon area 102 for selecting a function for searching and correcting a target drawing, and a drawing display area 103 for displaying a drawing searched by the mouse operation.

The process of displaying the target facility drawing on the drawing display area 103 and performing the hierarchical selection of the hierarchical three-dimensional display, the coordinate conversion of each selected hierarchy, and the composite display of the selected hierarchy is performed on the display drawing according to the following procedure.

Using the mouse 207 shown in FIG. 2, the cursor CU that moves in one-to-one correspondence with the operation of the mouse 207 is moved to the icon area 102 on the display screen 101, and the "screen search" icon is selected and instructed. You can search the drawing directly
There are a drawing No. search to specify the No., a search drawing search to search the target drawing from the index diagram showing the positional relationship of the whole drawing, a target search by the target specification, a town name search by the town name designation, etc. Use them according to the application. When this selection command is input to the CPU 201, the graphic search unit 105 of the CPU 201
Index the corresponding drawing data from the file device 203 and temporarily store it in the main memory 202. The display editing unit 110 edits the drawing data in accordance with the drawing display area 103 and displays the drawing data in the drawing display area 103.

Next, a case will be described in which a stereoscopic display hierarchy is selected from the display drawings and a target stereoscopic display screen is created.

By operating the mouse 207, the cursor CU is moved, and a command for selecting the “layer selection” icon in the icon area 102 is issued. This selection command is input to the hierarchical display definition unit 105 of the CPU 201.

The hierarchy-based display definition unit 105 receives the designation of the hierarchy to be separated and displayed on the display screen by operating the mouse 207, selects the hierarchy, and stores the result in the main memory 202.

Next, a command to select the “hierarchical three-dimensional display” icon in the icon area 102 is issued. This selection command is sent to the operation input unit 10 of the CPU 201.
4 and passed to the coordinate conversion unit 108. The coordinate conversion unit 108 applies a parallelogram coordinate conversion to the figure before the coordinate conversion shown in FIG. As a result, as shown in FIG. 5 (b), a figure which is compressed in the Y-axis direction while maintaining the overall positional relationship is created.

The hierarchical integrated editing unit 109 three-dimensionally arranges and edits the selection hierarchy in order to represent the graphics of each selection hierarchy created by the coordinate conversion unit 108 on the same screen. FIG. 6 shows an example in which a pipe map for each year is selected and three-dimensionally arranged with respect to a topographic map.

In this way, the hierarchy is selected from the pipeline drawing data and the selected hierarchy is three-dimensionally edited, whereby the secular change of the pipeline can be quickly and accurately grasped.

〔The invention's effect〕

As described above, according to the present invention, among facility drawings composed of graphic data obtained by superimposing hierarchical data separated into a plurality of hierarchies and attribute data indicating the attributes of the graphic data, hierarchical data at an arbitrary hierarchical level is obtained. Since a drawing management device capable of displaying a plurality of three-dimensional images in a time series on the same screen of the display device can be provided, the correction history of hierarchical data in an arbitrary hierarchy can be grasped on one screen.
