DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a schematic distribution pipe diagram display device for automatically creating and displaying a schematic distribution pipe diagram which allows a user to grasp at a glance the general distribution pipe state in a certain water supply area. About.

[0002]

2. Description of the Related Art Water supply companies such as local governments prepare a detailed map of various water distribution pipes buried on roads and the like in their own water supply area, for example, by creating a distribution pipe diagram shown in FIG. Managing. In this distribution pipe diagram, each building and road are described in detail as shown in the figure, where each distribution pipe is buried on the road, the diameter, material, installation year, valve position of the buried distribution pipe. , Branch position, etc. can be easily understood. In the water supply works, etc., construction will be performed using this water distribution pipeline diagram.

[0003] Hundreds of such detailed distribution pipe diagrams are created and stored so as to cover the entire water supply area. In addition, a pipe network diagram showing the flow of water in the entire water supply area is prepared. In this pipe network diagram, unlike the water distribution pipe diagram described above, the flow direction, the pressure, and the like are superimposed and described on a pipe network model obtained by extracting and modeling a water distribution pipe under a certain condition from a water distribution facility.

[0004]

However, there is also a problem that the staff of the water supply company cannot easily confirm the general water distribution pipe state in the entire water supply area even in the above-mentioned water distribution pipe diagram and pipe network diagram. That is, in the distribution pipe diagram, as shown in FIG. 8, the buried position information and the distribution pipe information (caliber, material, installation year, etc.) can be grasped, but the information on the flow of water (flow direction, pressure, etc.) Not described.
Therefore, it was difficult to grasp the flow of water after the reservoir by this distribution pipe diagram. Also, in order to grasp the overall flow, it is necessary to spread and examine a huge number of distribution pipeline diagrams.

Further, in a pipe network diagram, since the pipe network itself is complicated, it requires skill to decode the pipe network, and the pipe network cannot be read unless a great deal of information on the drawing is followed. On the other hand, in the case of water cutoff, water pipe breakage, etc., it is necessary to immediately grasp the direction of water flow and make a global judgment in a short time, such as controlling opening and closing of a valve at an appropriate position.

Therefore, there is a problem that it is not possible to make a correct decision in a short time in the above-mentioned water distribution pipe diagram and pipe network diagram. The present invention has been made in view of such circumstances, and by extracting only necessary information from a water distribution pipe map, a map, and height information, the flow of water in the entire water supply area is intuitively realized. It is an object of the present invention to provide a schematic distribution pipeline diagram display device capable of automatically displaying a schematic distribution pipeline diagram that can be globally grasped, and obtaining a correct decision on a distribution pipeline in a short time.

[0016]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a schematic configuration of a schematic distribution pipe diagram display device of an embodiment. This schematic water distribution pipe diagram display device is roughly divided into a database 1 formed in a magnetic disk device for storing various information, and a CRT display device or the like, which is finally created and displays the schematic water distribution pipe diagram. It is composed of a display 2 configured, an operation unit 3 configured by a keyboard or the like for a monitor to input various operation commands, and an information processing unit configured by a computer that executes various information processing.

3, switching section 14a. 14b is provided. Each of these parts 4 to 14a. 14b is formed in software on the application program. The bird's-eye view creation program 9 is, for example, a commercially available program.

The database 1 further includes a water distribution pipeline map 15, a topographic map 16, a height information map 17, and a reservoir information 1
8, a water distribution block diagram 9, a customer detailed map 20, and the like are stored.

As shown in FIG. 8 described above, the distribution pipe diagram 15 shows a reservoir, a distribution pipe route, and a diameter, a material, a laying year, and a valve of each distribution pipe for supplying water to each customer in a certain water supply area. The position, branch position, and the like are indicated. This distribution pipeline diagram 1
5 is described as data over one or more sheets.

The topographic map 16 is a topographic map in which contour lines 32 issued by the Geospatial Information Authority of Japan are described. In the height information map 17, information on the ground height at each position in the topographic map 16 is stored. Reservoir information 17 includes the name, storage volume, and water level (LW) of each reservoir in the service area.
L) and other information are stored.

Water Distribution Block FIG. 19 is a diagram showing the position of each water distribution block 22 when the water supply area 21 is divided into a plurality of water distribution blocks 22 as shown in FIG. In addition, as shown in FIG.
It is a detailed home map in which roads, customer positions, and customer names are described.

Next, the operation of the schematic water distribution pipe diagram display device thus configured will be described step by step. When the observer inputs a schematic diagram creation command via the operation unit 3, the switching unit 14a is first turned on and the switching unit 14b is shut off.

Then, the display distribution pipe diagram creating section 4 operates, and the reservoir 24, the water distribution pipe 27 having a certain diameter or more, and the water distribution pipe 27 in the water distribution pipe diagram 15 stored in the database 1 are attached. The valve 25 and the diameter 26 are extracted to create a display distribution pipe diagram 23 shown in FIG. And work
Show Display water distribution pipeline diagram 23 that formed the display 2.

Next, the topographic map processing section 5 is activated, reads the topographic map 16 from the database 1, and superimposes the topographic map 16 on the display distribution pipe map 23 being displayed on the display 2 as shown in FIG. . Therefore, the road 31 and the contour lines 32 are displayed in the display distribution pipe diagram 23.

Further, the height information processing unit 6 is activated,
The numerical value of the height of the water distribution pipe 27 designated by the operation unit 3 is read from the height information map 17, and the height numerical value 28 is displayed at the corresponding water distribution pipe 27 position.

Further, the reservoir information processing unit 7 is activated,
Reservoir name 29, water surface height (LW
L) 30 is read out and superimposed and displayed at the corresponding position. In addition, the water distribution block diagram processing unit 8 is activated, and the water distribution block diagram 19 is started.
The boundary line 33 of each water distribution block 22 is displayed.

By the above-described superimposition processing, the schematic water distribution pipe diagram 34 shown in FIG. In the schematic water distribution pipe display device configured as described above, the water distribution pipes 27 having a predetermined diameter or more of the water supply area 21 are displayed in the schematic water distribution pipe diagram 34 displayed on the display 2, and each of the water distribution pipes is displayed. 27
The ground height numerical value 28 and the water surface height 30 of the reservoir 24 are displayed. Therefore, the observer can easily grasp in which direction the water flows at each water pipe 27 position.

Next, a process for displaying a schematic water distribution pipe map in a bird's eye view will be described. In this case, the switching unit 14a is shut off and the switching unit 14b is turned on. First, bird's-eye view creation unit 1
0 is activated, and a bird's-eye view 34 of the corresponding distribution area shown in FIG. 6 is created for the topographic map 16 and the height information map 17. The process of creating the bird's-eye view 34 is created using the bird's-eye view creation program 9 that has already been technically established.

Next, the display water distribution diagram deforming unit 11 displays the distribution water distribution diagram 23 which has already been created by the display water distribution diagram creating unit 4.
Is transformed in accordance with the bird's-eye view 34. Specifically, each water distribution pipe 27 is deformed by setting its height position on the assumption that it is buried at a specified depth below the ground surface such as 1.2 m. Then, the modified display water distribution diagram 23 and the bird's-eye view 34 are superimposed on the display 2 as shown in FIG.

The boundary line 33 of the water distribution block 22 read from the water distribution block diagram 19 is similarly subjected to a deformation process, and is superimposed on the modified display water distribution diagram 23 and the bird's-eye view 34.

Further, the ground height value 28 and the reservoir 24
Is also superimposed on the modified display water distribution diagram 23 and the bird's eye view 34. Accordingly, the schematic water distribution pipeline diagram 34a is displayed on the display 2 in a bird's eye view as shown in FIG.

Therefore, even if the observer does not actually read the numerical value 28 of the base height at the position of each water pipe 27,
It is possible to judge at a glance the base height relationship between the positions of the respective water distribution pipes 27. Therefore, the flow direction of the water in each water distribution pipe 27 can be more easily grasped.

Next, the display of the water stop position will be described with reference to the schematic water distribution pipe diagram 34a of FIG. Generally, in a distribution network, water flows from a higher pressure to a lower pressure, but the pressure of water flowing out of the reservoir 24 depends on the potential energy of the water in the reservoir 24. Normal water supply requires a pressure of at least 2 kg / cm ² and a loss of about 0.1 kg / cm ² due to friction in the water supply, which is about 2.1 kg / cm ² .

Since this water pressure is equal to the water pressure when water is naturally flown from a height of 21 m, (LWL-2
1) Water that has flowed to a point with a base height (elevation) of less than
It will not flow to a point with an altitude of (LWL-21) m or more. The boundary point where this water stops flowing is the water stop position 35
It is.

In the schematic distribution pipe schematic 34a, the reservoir 24
30. Water surface height (LWL) Ground height 28, contour line 32
Is known, the water stop position 35 can be easily obtained. The water stop position 35 on the water distribution pipe 27, the water supply possible range 38, and the water impossible capacity range 39 are displayed, for example, in different colors.

Therefore, the reservoir 24 may be
For example, when the water level (LWL) 29 is lowered, if the minimum pressure condition is input in the designated condition 38, the water stop position 35 is found out, and it is impossible to supply water to the pipes after the water stop position 35. Become.

[0037] In this case, it is expected that the customers near this will be cut off. The monitor designates the corresponding water cutoff area 39 with the operation unit 3 and activates the enlargement processing unit 13. Then, the enlargement processing unit 13 reads out the corresponding area 20a of the customer detailed map 20 in the database 1, transforms it to the bird's-eye view 34 by the above-described method, and displays it as shown in the enlarged view 34b of FIG. Is superimposed on the display 2.

Therefore, the name of each customer 40 existing in the water interruption area 39 can be easily grasped. Therefore, when the water level (LWL) 30 of the reservoir 24 is reduced due to a drought or the like, the water interruption area 39 can be accurately grasped, and how many customers 40 are included in the water interruption area 39. Can be predicted.

Further, even in the case where a water pipe becomes impossible due to a breakage accident in a part of the water pipe 27, water cannot be sent to the water pipe 27 in any direction from the accident location. It can be easily grasped that the water level is cut in a certain area. Therefore, even in an emergency, the water supply state can be appropriately determined, and the determination of which valve 25 should be controlled to open / close can be executed in a short time.

[0040]

As described above, in the schematic water distribution pipeline map display device of the present invention, only necessary information is extracted from the water distribution pipeline map, the map, and the height information and displayed as a bird's eye view. > By this, it is possible to automatically display a schematic water distribution pipe diagram that allows intuitive and global understanding of the flow of water in the entire water supply area, and even in an emergency such as an accident, correct the water distribution pipe in a short time. You can get judgment.

Further, since the water stop position in the water distribution pipe can be automatically calculated and displayed based on the displayed water surface height of the reservoir and the ground height of each water distribution pipe position, an abnormality such as a drought or water pipe breakage occurs. Sometimes, the range of water interruption can be grasped intermittently.
