Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an input unit for inputting drawing information on a fluid supply pipe network facility consisting of a plurality of sheets, and a shape data generating unit for generating shape data for each facility from the inputted drawing information. The present invention relates to a drawing information management device in which a display unit that displays drawing information based on generated shape data and a storage unit that stores generated shape data are connected to a computer body.

[0002]

2. Description of the Related Art Generally, a drawing for a fluid supply pipe network facility is composed of a plurality of sheets. For example, in a city water supply and distribution pipe network facility with a population of 100,000, a 1/500 scale division diagram ( About 50 sheets (50 cm x 35 cm) will be the drawing of the entire water supply distribution network facility. Here, the drawing information is input from an input unit such as a digitizer, but since it is impossible to input a plurality of pieces of drawing information at one time, it is normally input one by one. Therefore, the entire drawing information is created by linking the individually input drawing information relating to the section maps on the computer.

[0003] However, a specific facility, such as a water pipe, which is arranged across adjacent drawing information, is not always connected smoothly at the drawing junction,
Usually, it is slightly deviated due to an input error or the like. In addition, since the shape data of each facility is managed for each drawing, there is an inconvenience that the facilities are managed as though they are separate facilities although they are actually common facilities. Therefore, conventionally, a first display area for displaying the specific drawing information being input from the input unit and adjacent drawing information based on the shape data stored in the storage device are displayed around the first display area. A display area setting unit that sets a second display area in the display unit is provided, and among the facilities displayed in the first display area, a specific facility extending between both drawings is displayed in the second display area. I was inputting while making changes to match the displayed endpoints of the facility.

[0004]

However, according to the above-mentioned conventional technique, the shape data of the specific facility arranged across the adjacent drawing information are matched with each other.
The drawing information displayed in the second display area is merely a diagram, and the shape data of the specific facility displayed in the second display area cannot be specified on the computer side. However, there is a drawback in that extremely complicated operations such as creating joint information that correlates the shape data of both drawing information with each other are required.

An object of the present invention is to eliminate the above-mentioned conventional drawbacks.

[0006]

To achieve this object, a characteristic configuration of a drawing information management apparatus according to the present invention comprises a first display area for displaying specific drawing information being input from the input section, and a first display area thereof. A display control unit that sets a second display area in the display unit that displays adjacent drawing information based on the shape data stored in the storage device around the display area, and the drawing information displayed in the first display area. And a shape data extraction unit that automatically extracts the shape data of both drawing information corresponding to the selected specific facility from the facility arranged across the drawing information displayed in the second display area. And a joint information generation unit that automatically generates joint information that associates each other from the shape data.

[0007]

When the specific facility is selected from the already input drawing information displayed in the second display area by the display control unit by using, for example, a mouse, the shape data extraction unit captures the shape data relating to the specific facility. When a specific facility is selected from the specific drawing information entered in one display area, the shape data relating to the specific facility is captured in the same way, so the bonding information generation unit displays the bonding information indicating that the shape data are the same facility. It is automatically generated.

[0008]

As described above, according to the present invention, the shape data of the specific facility arranged across the adjacent drawing information are matched with each other, and the joining information for associating the corresponding shape data with each other is automatically created. It is now possible to provide a drawing information management device with excellent operability.

EXAMPLES Examples of the present invention will be described below. As shown in FIG. 1, the water supply pipe network facility management device is a computer system that manages drawing information representing the arrangement of a fluid supply pipe network facility, and is a digitizer for inputting drawing information to the computer main body 1. An input unit 2, a display unit 3 such as a CRT that displays the input drawing information, and a storage unit 4 that is a magnetic disk that stores the input drawing information.
And an output unit 5 such as a printer that outputs drawing information.

A drawing relating to a water supply facility such as a water distribution pipe or a valve plug is composed of a plurality of zoning drawings. Each zoning drawing as shown in FIG. 2 is arranged on a digitizer, and the pipes and valves shown in the drawing are arranged. Input the stopper position. At that time, each drawing is arranged on the digitizer, and by inputting the origin set as the reference position of each drawing, a predetermined point in the x-axis direction, and a predetermined point in the y-axis direction, When establishing a coordinate system for each section map and editing it in the overall drawing, the section map is added to the origin of each drawing by adding offset data in the x-axis and y-axis directions indicating the positional relationship between the drawings. Take a match between.

As shown in FIG. 3, the drawing information is allocated to different storage hierarchies L1, L2, L3, ... For each facility such as road, house, water pipe, water pipe, valve plug, etc. Is first stored in the internal memory of the computer main body 1 and then stored in the storage unit 4 as a whole. More specifically, each storage hierarchy L1, L2, L3, ...
The facilities assigned to ... Are generated and managed as shape data including coordinate data indicating the location of the facility by the shape data generation unit 1a which is a part of the computer main body 1. In the case of water pipe, Fig. 4
As shown in (a), the conduit shape data is defined for each water distribution pipe arranged in each drawing information and becomes one file.
Pipeline shape data includes the drawing number corresponding to the division diagram where the pipeline is arranged, the unique pipeline number in all drawings,
It is made up of the pipe type, the starting point intersection number, the ending point intersection number, the maximum coordinates and the minimum coordinates of the pipe arrangement area, and the number of break points. The intersection coordinates of the starting point and the ending point included in the pipeline shape data are shown in FIG.
As shown in (b), it is managed in the intersection shape data file, and the break point coordinates are managed in the break point coordinate data file as shown in FIG. It should be noted that the intersection means a point where the pipelines intersect with each other, and the break point means a bending point of one pipeline. Similarly, in other facilities, the shape data generation unit 1a generates shape data including the arrangement coordinates and the like and stores the shape data in the storage unit 4.

The display unit 3 displays drawing information based on the shape data input from the digitizer and generated by the shape data generation unit 1a. More specifically, first, the display control unit 1b which is a part of the computer main body 1 stores the shape data file regarding the adjacent drawing information read from the storage unit 4 in the internal memory (not shown) of the computer main body 1. , A display memory (not shown) that expands bitmap data as output data to the display unit 3,
As shown in FIG. 1, a first display region R1 for displaying the specific drawing information currently input from the input unit 2 and the first display region R1.
A second display area R2 for displaying adjacent drawing information based on the shape data stored in the storage unit 4 is set around the, and based on the shape data stored in the internal memory, a pipe line or the like is displayed in each display area. Develop the diagram. Then, the display unit 3 displays the drawing information based on the line drawing data expanded in each display area.

The operator visually checks the already input drawing information displayed in the second display area R2, and selects the facility arranged across both drawing information in the drawing information currently being input. Recognizing, the layout of the diagram is corrected using a pointing device such as a mouse so that the diagram representing the facility is aligned at the boundary between the drawings without displacement. Shape data generator 1
“A” itself corrects the corresponding shape data based on the corrected diagram.

After that, when the operator selects the facility displayed in the second display area among the facilities arranged across both the drawing information by using the pointing device such as a mouse, the computer main body is selected. The shape data extraction unit 1c that is a part of 1 automatically extracts the shape data corresponding to the selected specific facility from the internal memory, and also obtains the shape data of the facility on the first display region R1 side corresponding to the specific facility. Also extracted from internal memory. Joining information generator 1
d automatically generates joint information that relates each other from the shape data. For example, when the specific facility is a pipeline, as shown in FIG. 5, a drawing number indicating the starting point side and the ending point side of the pipeline, each pipeline number, a pipeline number that unifies them, and the like. The road junction data file is automatically generated.

The above operation will be described with reference to the flowchart shown in FIG. The operator first operates the digitizer while visually observing the adjacent drawing information in the second display area of the display unit 3, and inputs the drawing information input as pointing data. The shape data generation unit 1a generates shape data including coordinate data indicating the location of the facility from the input pointing data and stores the shape data in the internal memory of the computer main body 1. The display control unit 1b develops a diagram in the first display area R1 of the internal memory for display based on the shape data stored in the internal memory, and the content is displayed on the display unit 3. The operator aligns the line diagrams between the adjacent drawing information while visually observing the display unit 3, and among the facilities related to the alignment, the facilities displayed in the second display region R2 and the first display region R1 are displayed. Select each facility using the mouse. The shape data corresponding to the selected facility is searched and specified in the internal memory. The joining information generation unit 1d automatically generates joining information that associates the shape data.

Another embodiment will be described below. Although the digitizer is used as the input unit in the above embodiment, an image reader or the like may be used instead. In the previous example, as a facility to be displayed in the second display area, the case of targeting all facilities has been described, but the facility to be displayed in the second display area is highly necessary to be matched between the drawings,
For example, it may be limited to a water pipe or the like. This improves the responsiveness of the display. In the previous example,
Although the drawing information management device related to the water supply network facility diagram has been described, the drawing information management device can be applied to the sewer facility or city gas network facility as long as it relates to the fluid supply network facility.

It should be noted that reference numerals are added to the claims for convenience of comparison with the drawings, but the present invention is not limited to the configurations of the accompanying drawings by the entry.
