As a method of searching for the outline installation drawing information, a method of displaying the installation drawing information of a large scale on the CRT 6 and indicating the approximate position of the construction target area by using the mouse 2, and inputting the municipal name and district name to the keyboard 3. Or a method in which the installation drawing information is classified and numbered in advance, and the number is input from the keyboard 3. The operator operates the mouse 2 on the screen display of FIG. 5A to display a frame 10 as shown in FIG. 5B and designates and inputs an area corresponding to the construction target area. (Step #
2).

Next, the data in the designated and input area is converted into a DXF file which is a data file format for maintaining data compatibility between general-purpose CAD systems (step # 3). The data is output to the communication line CL via the communication line (step # 4). To the communication line CL, a drawing device FM configured by a general-purpose CAD system or the like is connected. A plotting apparatus FM illustrated in FIG. 1 includes an arithmetic unit 20 that performs data processing related to various plots, a mouse 21 and a keyboard 22 for inputting various data, a plotter 23 that prints out drawing information and the like, drawing information and the like. Communication interface 2 for inputting and outputting various drawing information and the like via CRT 24 for displaying images and communication line CL
And an external storage device 26 for storing drawing information and the like.

When the drawing apparatus FM receives the installation drawing information of the construction target area output by the pipe network facility management apparatus PS via the communication interface 26, the drawing apparatus FM sends the DXF file format data to the drawing apparatus FM. Convert to a unique data format. Based on the installation drawing information after the data format conversion, a construction drawing such as a construction design drawing and a construction completion drawing as shown in FIG. The construction drawing of FIG. 5C illustrates a case where the construction for changing the installation position of the valve plug 30 is performed. Also, in the installation drawing information, the intersection 4
Although one space is represented as one pipe, the actual pipe network has a configuration in which a plurality of fluid supply pipes 40 of a fixed length are connected. Is performed to clarify the position of the fluid supply pipe 40. The construction drawings created by the drawing device FM are stored in a database as construction records in the external storage device 26 as necessary.
Also, when there is a data output request from the pipe network facility management device PS and the construction drawing is to be output to the communication line CL, D
Convert to XF file format and output.

Next, a process until the pipe network facility management apparatus PS receives the construction drawing created as described above and stores it in the installation drawing information database will be described with reference to the flowchart of FIG. First, after issuing a data output request to the drawing device FM, the construction drawing is received via the communication interface 7 (step # 10). Then, the received construction drawings are converted from DXF file format
The data is converted into a data format unique to the pipe network facility management device PS (step # 11). When this conversion is completed, the installation drawing information of the construction target area (hereinafter sometimes simply referred to as “installation drawing information”) and the received construction drawing are displayed on the CRT 6 simultaneously or alternately (step #).
12). The operator designates and inputs a design corresponding to the displayed installation drawing information of the construction target area and the received construction drawing (step # 13).

The specification input process will be described with reference to a specific example. The design specified and input from the mouse 2 on the installation drawing information side is a schematic diagram of a house as shown in the left column of FIG. When the symbols on the construction drawing side designated and input from the mouse 2 as the corresponding ones are as shown in the right column of FIG. 7B, each of these symbols is composed of four line segments. Therefore, as shown in FIG. 7B, the numbers corresponding to the four line segments are assigned and displayed on the CRT 6. The operator looks at the display of FIG. 7 (b), and designates and inputs from the keyboard 3 with the number given the corresponding line segment in the installation drawing information and the construction drawing. For example, No. 3 on the installation drawing information side and No. 4 on the construction drawing side are designated and input.
When two designs are designated, the azimuth and scale of the entire construction drawing are changed so that the two designated designs match (step # 14). That is, 3 on the installation drawing information side
The drawing is changed so that the number line segment matches the number 4 line segment on the construction drawing side. As the design to be designated and input, various figures such as characters or symbols can be used as long as they are displayed in the drawing.

Next, the installation drawing information and the changed drawing information are compared by a subtraction process or the like to extract a changed portion (step # 15), and the CRT 6 is displayed in different colors to identify the changed portion. (Step # 16). At the time of displaying the changed part, the drawing data of the installation drawing information is displayed in a different color from the display color of the changed part in the part other than the changed part. When the operator confirms the display and instructs the old data on the installation drawing information side of the changed portion with the mouse 2 to instruct the correction, the designated diagram and the like and the attribute data thereof are deleted ( Step # 17).

Further, when one fluid supply pipe 40 of the new data on the construction drawing side among the changed parts is designated and input by the mouse 2 (step # 18), the designated fluid supply pipe 40 is inputted.
The fluid supply pipes 40 connected in series with each other are connected one after another until an intersection 41 of the pipe network first appears, and the intersection 41
The space is connected to one pipe 42 (step # 19). Specifically, for example, assuming that the installation drawing information after deleting the old data is as shown in FIG. 8, one of the fluid supply pipes 40 divided and individually shown.
When one of the fluid supply pipes 40a is designated by the mouse 2, the fluid supply pipes 40 existing on the left and right sides in the flow path direction starting from the designated fluid supply pipe 40a are successively connected to one conduit 42.
The connection operation is terminated when the closest cross connection points 41a and 41b appear on both the left and right sides in the flow path direction. The determination as to whether or not the intersection 41 is made is based on attribute information indicating whether or not the pipe type is a branch joint, or whether or not the pipes intersect and the positions of the intersecting pipes in the vertical direction are the same. It can be determined by whether or not. The changed part where the connection processing of the pipe network has been completed is changed to the same color as the display color of the installation drawing information of the part other than the changed part, and the operator can confirm that the drawing of the changed part has been incorporated into the installation drawing information. Like that. When the installation drawing information is updated in this manner, the updated installation drawing information is stored in the database of the external storage device 8 (step # 2).
0).

In summary of the operation of the arithmetic unit 1, the arithmetic unit 1 has a control configuration as shown in FIG. 1 and functions together with the mouse 2 as an area specifying means AP for specifying a construction target area. Together with the pipe designating means PP, which designates and inputs an arbitrary fluid supply pipe 40 in the construction drawing, the fluid supply pipe 40 designated by the pipe designating means PP is used.
The closest cross connection point 41 on each side of the flow path direction
Function as a drawing change unit FT for executing a change process of combining the fluid supply pipe 40 located between the detected cross connection points 41 into one pipe line 42, and further, the change by the drawing change unit FT.
