Fig. 4, Fig. 4 is a diagram showing a database configuration of facility drawings, Fig. 5 is a diagram showing a display example of a water cutoff area, Fig. 6 is a configuration diagram of block data related to drawing retrieval, and Fig. 7 is an entire drawing display device. It is a block diagram which shows a structure.

In the present embodiment, as the distribution pipe data including the distribution pipe 101 as a route and the valve plug 102 as the demarcation part in the facility drawings across the plurality of drawings # 1 to # 16,
Display data of the water pipe 101 and the valve plug 102 in each drawing are set, and data indicating whether or not the valve plug 102 as an opening / closing element exists in the water pipe 101 and the connection relation of the water pipe 101 Data specifying adjacent drawings is set for each drawing. The latter data is set in association with the virtual valve plug 103 provisionally installed at the boundary between each drawing and the adjacent drawing.

That is, based on the distribution pipe data of the facility drawing having the positional relationship as shown in FIG. 2 (data in a state where the distribution pipe 101 and the valve plug 102 are laid across the adjacent map peculiar to the map) , When the drawing of # 6 is displayed on the screen as the facility drawing, as shown in FIG.
When one specific point is designated as the water cut point 104, the search for the presence or absence of the virtual valve plug 103 set at the end of the path of the water distribution pipe 101 connected to the water cut point 104 is executed.
When it is found that there are four virtual valve plugs 103, the drawing including the water pipe 101 connected to each virtual valve plug 103 is searched, and as a drawing adjacent to the drawing of # 6, # 2, Drawings # 5, # 7, and # 10 are selected. Further, a search is performed to determine whether the valve plug 102 is present in each selected drawing. Then, when the valve plug 102 is present in each drawing, the search for data relating to this drawing is completed. In this case, the valve plug 102 is shown in the drawings of # 2, # 5, and # 7.
Exists, the search for data relating to these drawings ends. Then, these drawings are displayed as images related to the water cutoff area, and the search results of these drawings are stored as drawing search related block data. For example, the drawing of # 5 is stored as the drawing of the left coordinate 1 based on the drawing of # 6, the drawing of # 7 is stored as the drawing of the right coordinate 1 based on the drawing of # 6, and the drawing of # 2 is # It is stored as the drawing of the upper coordinate 1 with reference to the drawing of FIG.

On the other hand, since the valve plug 102 does not exist in the drawing of # 10, the drawing including the water distribution pipe 101 connected to the virtual valve plug 103 of the drawing of # 10 is searched and the water distribution pipe 101 of the water cut point 104 is searched. # 10 from the connection relationship of the connected water pipes
The drawing of # 14 is selected as the drawing adjacent to. Then, it is searched whether or not the valve plug 102 is present in this drawing. In this case, the water cut point 10 of the water pipe 101 in the drawing of # 14
Since the valve plug 102 exists in the conduit of the water distribution pipe 101 connected to the No. 4, the search for the data relating to this drawing is completed, and the search result is stored as the drawing search related block data. This data is stored assuming that the drawings of # 10 and # 14 are drawings of the lower coordinate 2 with reference to the drawing of # 6.

When the search result for selecting the drawing related to the water cutoff area is stored as the drawing search related block data based on the drawing of # 6, the drawing search related block data is stored as the drawing search related block data. After that, only by searching the drawing search related block data, it is possible to quickly search for the drawing related to the water cutoff area based on the drawing in which the drawing search related block data is stored.

Next, the processing contents for searching for and displaying the drawing related to the water cutoff area according to the drawing search related block data will be described with reference to the drawing.

First, in step 401, the corresponding water pipe drawing is searched from the facility drawings stored in advance in the file device 303 of FIG. 7, and the specified water pipe drawing is displayed on the screen of the CRT display device 305. To do. That is, the facility drawing displayed on the CRT display device 305 is displayed based on the facility drawing data 201 as shown in FIG. Moreover, this drawing data 201 is shown in FIG.
~ (4), the road figure 202, the house frame figure 20
3, the distribution pipe figure 204 and the like are separated into a plurality of layers. Therefore, in order to display the water cutoff area, the distribution pipe layer 2
The 04 data is extracted and the distribution pipe drawing is displayed. After the drawing of the water distribution pipe is displayed, a specific portion of the drawing of # 6 is designated as the water cut portion 104 (step 402).

Next, at step 403, the water cut point 10
Based on the drawing # 6 including 4 in the drawing, the drawing search related block data in FIG. 6 is searched. This block data is
When an arbitrary portion of the water distribution pipe 101 in the drawing # 6 is designated as a water cut portion, the drawings related to the water cut portion can be extracted based on the drawing # 6. Therefore, when the drawing search related block data regarding the drawing of # 6 is searched, the drawing of # 5 is extracted as the drawing of the left coordinate 1, the drawing of # 7 is extracted as the drawing of the right coordinate 1, and the upper coordinate 1 is extracted. The drawing of # 2 is extracted as the drawing of
Furthermore, the drawings of # 10 and # 14 are extracted as the drawings of the lower coordinate 2. Then, the extracted drawings (# 2, # 5, #
7, # 10, # 14) and # 6 drawing images are displayed as shown in FIG. 5 (step 404).

Next, in step 405, in order to identify the water cutoff region water pipe 105 that forms a closed loop region between the water pipe 101 connected to the water cut point 104 and the valve plug 102, the water pipe data is lined. Track and limit water interruption areas. That is, the water pipe 10 including the water cut point 104 in the pipe line.
The water cut-off area is limited by searching for the presence or absence of the water distribution pipe 101 having a connection relationship with 1 and the presence or absence of the valve plug 102 in the water distribution pipe 101.

After the water cutoff area is limited, the display color of the water cutoff water pipe 105 is changed to a color different from the display color of the other water pipes 101 (step 406). As a result, the water cutoff area can be displayed separately from other areas, and the water cutoff area can be easily identified.

In the above-mentioned embodiment, the example of the water supply pipe has been described, but the present invention is not limited to this and can be applied to the sewer pipe. Furthermore, the state of the circuit breaker at the time of power failure of the power distribution line,
Alternatively, the invention can be applied to detection of leaks in gas pipes, and in addition, to determining a detour when an accident occurs in traffic control.

[0023]

As described above, according to the present invention,
Since the route of the water cutoff area is displayed in a different color from the route of the other area, the water cutoff area can be displayed separately from the other areas, and the water cutoff area can be easily identified.
