Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drawing data management method for managing drawings relating to outdoor wiring work and the like using a computer.

[0002]

2. Description of the Related Art FIG. 7 is a block diagram showing a conventional drawing data management system for managing wiring work drawings. In the drawing, 1 is a master in which drawing data showing a current wiring situation in a certain area is accumulated. Drawing database (hereinafter,
A master drawing D / B), 2 is a design drawing database (hereinafter, referred to as a “design drawing database” that stores design drawing data of a design drawing for newly constructing a construction target area in the above-mentioned certain area.
Design drawing D / B).

Next, the operation will be described. First, FIG.
As shown in (a), the drawing data of the construction target range is read from the master drawing D / B1. In this example, there are two utility poles, an electric wire, and a house shape. Using this drawing as the original drawing, a design drawing is added with small columns, service lines, etc., as shown in FIG. Next, in FIG. 2C, the construction contractor carries out the construction by directly referring to this design drawing or by referring to the one that is once stored in the design drawing database 2 and read out. After the construction is completed, the design drawing is corrected as needed and then stored in the design drawing D / B2 as shown in FIG. Then, the construction fee is settled based on the stored design drawing.

Next, the master drawing D / B1 is updated. This is because only the part added in this construction from the above-mentioned design drawing, that is, only the part added to the original drawing in FIG. 3A is extracted as shown in FIG. 2E, and the master drawing D / B1
Update the target range of. Thereafter, this updated drawing is used as the original drawing for the next design. Such a drawing update is performed using the drawing update program, for example, once a day at a fixed time for each design drawing that has been posted on that day.

Next, overlapping design will be described with reference to FIG. First, as shown in FIG. 3A, the master drawing D / B1
Read the original drawing from. Next, as shown in FIG. 6B, a design drawing to which telephone poles and service lines are added is created, and this is stored in the design drawing D / B2 as the A design (parent design). Next, as shown in (c) of the figure, a range overlapping with the original figure of (a) (however,
(Coordinates and scales are arbitrary), and when the corresponding part is read from the design drawing D / B2, A as shown in FIG.
A blueprint for the design is obtained. A transformer and a lead-in wire are further added to this A design as shown in (e) of the same figure, and this additional portion is stored in the design drawing D / B2 as a B design (child design).

In the case of performing work by overlapping design such as the above-mentioned A design and B design, normally the work of A design which is a parent design is completed and then the work of B design which is a child design is carried out. If the work is simple, the work for design B may be completed first. In such a case, the drawing update for the B design is performed before the A design.

[0007]

Since the conventional method for managing drawing data is configured as described above, when the work for B design in the overlapping design is completed before the work for A design, the drawing master D / When the drawing of B1 is updated, the update of the B design is performed in the state where the update of the A design is not performed. Therefore, in the example of FIG.
In the master drawing D / B1, the utility pole indicated by 102 where the transformer and the drop wire in FIG. The drawing update program is started once a day, for example, and executes the program indifferently with regard to the order of completion of construction of overlapping designs, so in the above case, it is processed as an abnormal case such as "there is no facility that should exist". To be done. In such a case, a special process such as a process called "temporary removal" or a process called "recovery" is performed, but there is a problem that one update time becomes very long.

The present invention has been made to solve the above problems, and an object of the present invention is to obtain a drawing data management method capable of correctly updating a drawing.

[0009]

A drawing data management method according to the present invention stores information on a parent design (or child design) when a design drawing data has an overlapping design portion, and at the same time, stores a child design drawing (or parent design). When the design drawing data is updated to the master drawing D / B, information indicating whether or not the parent design drawing (or child design drawing) data has already been updated is stored.

[0010]

In the drawing data management method according to the present invention, the contents of the design drawing data created earlier in time are reflected in the master drawing D / B before those created later. It is possible to create and maintain the correct master drawing D / B.

[0011]

EXAMPLES Example 1. An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 1 is the master drawing D / B described above,
2 is the same as the design drawing D / B, 3 is the drawing update program for updating the contents of the master drawing D / B1 using the design drawing data of the design drawing D / B2, and 4 is the design drawing of each design drawing in the design drawing D / B2. It is process management data for managing the process.

Table 1 shows an image of the process control data 4, and stores process information corresponding to the design number, the design number of each design drawing, and the parent-child relationship of each design in a table format. The process information includes the update status of the drawing for each design drawing.

[0013]

[Table 1]

Next, the operation will be described. When the child design process is completed, the design drawing data is reflected on the master drawing D / B1 using the drawing update program 3. Figure 2
9 is a flowchart showing the processing of the drawing update program 3. In FIG. 2, when the drawing update program 3 is started in step ST21, the drawing update target design drawing data whose process is completed is extracted from the design drawing D / B2 in step ST22, and the process is executed until the target data ends in step ST23. Repeat. In step ST24, the process control data 4 in Table 1 of the design drawing data to be updated is searched to refer to the parent design drawing data. If the parent design drawing data has been updated in step ST25, the process branches to step ST26, and if not, the process repeats to steps ST22 to ST25. In step ST26, the master drawing D / B1 is updated under the condition that the parent design drawing data has been updated. It should be noted that as with the conventional drawing update method, the drawing update program 3
Is activated every day at a fixed time (multiple times can be set).

Example 2. In the first embodiment, the method of acquiring the update status of the parent design drawing data when updating the drawings of the child design drawing data in steps ST24 and ST25 has been described. A method of registering “parent design updated information” in the data and making a determination may be used. In FIG. 3, the configuration is shown in FIG.
1, the reference numerals 1 to 4 respectively correspond to FIG. 1, but the drawing update order is different from that in FIG. 1 and indicates that the parent design drawing data is updated first.

FIG. 4 is a flow chart showing the processing of the drawing update program 3 of FIG. The basic operation of this process is the same as in FIG. 2, but the check method is different.
In step ST44, it is determined whether or not the update is based on the parent design update completion information (held in the update target design drawing data). The parent design updated information is set in the design drawing data when the parent design drawing data of the design drawing data is updated, and similarly in step ST45, for the child design drawing data of the design drawing data. The updated information is set in ST46.

In order to allow the parent design drawing data to recognize the child design drawing data, when registering the child design drawing data in the design drawing D / B2, duplicate information must be registered in the parent design drawing data. FIG. 5 is an image diagram when registering design drawing data. Reference numeral 5 indicates a registration processing program. FIG. 6 is a flowchart explaining the registration processing program 5 of FIG.

In step ST60, the registration processing program 5
Is started, it is checked in step ST61 whether or not the parent design drawing data is used.
At 62, information such as a child design number is registered in the corresponding parent design process management data of the process management data 4. Then step S
After the design drawing data is registered in the design drawing D / B2 at T63, the process ends at step ST64. When the parent design drawing data is not used in step ST61, the design drawing data is registered as it is in step ST63.

[0019]

As described above, according to the present invention, the information indicating the overlapping design is used when updating the drawing.
Drawing updates that are consistent in time (synchronized) can be performed, and anomalous cases such as "there is no facility that should exist" can be greatly reduced. Further, by reducing the number of abnormal cases, there is an effect that the reliability of the drawing update process is improved.
