DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an input section for inputting drawing information relating to a plurality of fluid supply pipe network facilities, and a shape data generating section for generating shape data for each facility from the input drawing information. And a display unit for displaying drawing information based on the generated shape data and a storage unit for storing the generated shape data connected to a computer main body.

[0002]

2. Description of the Related Art In general, a drawing relating to a fluid supply pipe network facility is composed of a plurality of sheets. For example, in a city water supply pipe network facility having a population of more than 100,000, a division diagram of a scale of 1/500 ( (50cm x 35cm) is about 800 sheets, which is the whole water supply and distribution pipe network drawing. Here, the drawing information is input from an input unit such as a digitizer, but since it is impossible to input a plurality of drawing information at a time, it is usually input one by one. Therefore, the entire drawing information is created by linking the drawing information relating to the individually-divided drawings on the computer.

[0005] However, specific facilities, such as water distribution pipes, which are arranged across adjacent drawing information are not always connected smoothly at drawing junctions.
Usually, there is a slight deviation due to an input error or the like. In addition, since the shape data of each facility is managed for each drawing, there is a problem that the facilities are actually managed as if they are different facilities from each other. Therefore, conventionally, a first display area for displaying specific drawing information being input from the input unit, and adjacent drawing information based on shape data stored in the storage device are displayed around the first display area. Providing a display area setting unit that sets a second display area on the display unit, among the facilities displayed in the first display area, for a specific facility spanning between the two drawings, the second display area The input was made while performing a change operation to match the displayed end point of the facility.

[0004]

However, according to the above-mentioned prior art, the shape data of the specific facilities arranged over 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. There is a drawback that an extremely complicated operation such as creating joint information that associates shape data of both pieces of drawing information with each other is required.

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

[0006]

In order to achieve this object, 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 unit; A display control unit that sets a second display area for displaying adjacent drawing information based on the shape data stored in the storage device on the display unit around a display area, and drawing information displayed in the first display area. And a shape data extracting unit that automatically extracts shape data of both pieces of drawing information corresponding to a specific facility selected from facilities arranged over the drawing information displayed in the second display area. And a joint information generating unit for automatically generating joint information for associating the two with each other from the shape data.

[0007]

When a specific facility is selected from the input drawing information displayed in the second display area by the display control unit using, for example, a mouse, the shape data relating to the specific facility is captured by the shape data extracting unit. When a specific facility is selected from the specific drawing information input in one display area, the shape data related to the specific facility is similarly captured, so that the bonding information generating unit provides the bonding information indicating that the shape data is the same facility. It is automatically generated.

[0008]

According to the present invention, therefore, the shape data of the specific facilities arranged over 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. And a drawing information management device with excellent operability can be provided.

[0009]

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

Drawings relating to water supply facilities such as water distribution pipelines and valve plugs are composed of a plurality of division diagrams. Each division drawing as shown in FIG. 2 is arranged on a digitizer, and the pipelines and valves shown in the drawings are arranged. Instruction input of the stopper position. At that time, each drawing is arranged on the digitizer, and by inputting an instruction of an origin set as a reference position of each drawing, a predetermined point in the x-axis direction, and a predetermined point in the y-axis direction, When a coordinate system for each division map is established and the whole drawing is edited, the division 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 consistency between.

As shown in FIG. 3, the drawing information is allocated to different storage hierarchies L1, L2, L3,... For each facility such as a road, a house, a water distribution pipe, a water supply pipe, a valve plug, and the like. Is stored first in the internal memory of the computer main body 1 and thereafter stored in the storage unit 4 collectively. More specifically, each storage hierarchy L1, L2, L3,.
The facilities assigned to ‥ and ‥ are generated and managed as shape data including coordinate data indicating the arrangement of the facilities by a shape data generating unit 1a which is a part of the computer main body 1. For example, the facilities are allocated. Fig. 4
As shown in (a), pipe shape data is defined for each water distribution pipe arranged in each piece of drawing information and becomes one file.
Pipe shape data includes a drawing number corresponding to the block diagram in which the pipe is located, a pipe number unique to all drawings,
It is composed of a pipe type, a starting point intersection number, an end 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 pipe shape data are shown in FIG.
As shown in (b), it is managed in an intersection shape data file, and the break point coordinates are managed in a break point coordinate data file, as shown in FIG. In addition, an intersection point refers to a point where a pipeline intersects, and a break point refers to a bending point of one pipeline. Similarly, for other facilities, shape data including arrangement coordinates and the like is generated by the shape data generation unit 1 a and stored 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 generating unit 1a. More specifically, first, the display control unit 1b, which is a part of the computer main unit 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 unit 1. In a display memory (not shown) for developing bitmap data as output data to the display unit 3, FIG.
As shown in the figure, a first display area R1 for displaying the specific drawing information currently input from the input unit 2, and the first display area 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 area, and a pipe line or the like is provided in each display area based on the shape data stored in the internal memory. Expand the diagram. Thereafter, the display unit 3 displays the drawing information based on the diagram data developed in each display area.

The operator looks at the already input drawing information displayed in the second display area R2, and selects a facility which is arranged across both drawing information among the drawing information currently input. Upon recognition, 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” corrects the corresponding shape data by itself based on the corrected diagram.

After that, when the operator selects a facility displayed in the second display area by using a pointing device such as a mouse, the facility is displayed on the computer main body. 1 automatically extracts shape data corresponding to the selected specific facility from the internal memory, and extracts the shape data of the facility on the first display region R1 side corresponding to the specific facility. Also extracted from the internal memory. Joining information generator 1
d automatically generates joining information for associating the two with each other from the shape data. For example, when the specific facility is a pipeline, as shown in FIG. 5, pipe numbers indicating the drawing numbers on the starting side and the end point of the pipeline, the respective pipeline numbers, and the pipeline numbers that unify them. The road junction data file is automatically generated.

The above operation will be described with reference to the flowchart shown in FIG. First, the operator operates the digitizer while viewing adjacent drawing information in the second display area of the display unit 3 to input 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 generated shape data in the internal memory of the computer main body 1. The display controller 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 contents are displayed on the display unit 3. The operator matches the diagram between the pieces of drawing information adjacent to each other while viewing the display unit 3 and, among the facilities related to the matching, the facility displayed in the second display area R2 and the facility displayed in the first display area R1. Are selected using a mouse. Shape data corresponding to the selected facility is searched and specified in the internal memory.
