Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a method for displaying a distribution line diagram.
[0002]
[Prior art]
The distribution line diagram display device displays on the distribution line diagram the figure and name of the distribution facility created and stored in the distribution line diagram by data maintenance in association with the street map. At that time, if the display center and scale are designated, the display target area on the distribution line map is specified, and the equipment figure included in the display target area is searched and displayed.
[0003]
Each facility or the base facility serving as the base of each facility has coordinates on the map, and when specifying the display target region, the facility of the coordinates included in the target region is searched.
[0004]
Creating and saving a large number of power distribution equipment figures and names during data maintenance takes time because it is necessary to examine all the figures when they are displayed on the screen to see if they are in the display area. Display slows down. Therefore, during data maintenance, the span and the display range of the utility pole included in the feeder are stored as rectangular coordinates for each feeder unit, and only the ones where the rectangular coordinates of the feeder are included in the display area are displayed and displayed during display. To increase speed.
[0005]
However, the number of distribution facilities is enormous, and searching for all facilities is very time consuming and impractical. Therefore, as shown in FIG. 5, in the units of feeders (distribution lines) A to D, the coordinates of the rectangles surrounding them are held, and a rectangle that overlaps the display area rectangle is first searched (feeder search), and roughly the target feeder A and B are specified. Subsequently, a search (equipment search) is performed using the coordinates of the facilities belonging to the feeders A and B. As a result, the distribution line map is displayed in a practical time.
[0006]
[Problems to be solved by the invention]
Distribution equipment has the largest number of spans (around 100,000 systems per system). As shown in FIG. 6, as the scale factor of the distribution line diagram increases, the gap becomes denser and the gap of the display target becomes enormous.
[0007]
The above display method makes the search process more efficient, but has no effect on the display process between the searched diameters. The display processing time is proportional to the number of spans to be displayed, which is a display bottleneck.
[0008]
The present invention has been made to solve such problems, and the object of the present invention is to switch to macro display when the scale magnification increases and the system is mixed, and the span of the display object is drastically reduced. It is providing the distribution line route map display method which can display a distribution line route map at high speed.
[0009]
[Means for Solving the Problems]
According to the distribution line graphic display method of the present invention, in the distribution line diagram display device for displaying the distribution facility graphic and name created and stored by the data maintenance process in correspondence with the street map, section data is generated by the facility data maintenance process. At the same time, also generate a point permutation in which the poles of the end points and branch points are arranged in one stroke, and if there is a branch point in the middle of this point permutation generation, put a delimiter code representing the branch point next to the end of the stroke stroke, If you continue to draw another route from the relevant branch point and search for the feeder to be displayed in the process of displaying the map, if you determine that the system is not dense, the actual span is displayed for each section, and the system is determined to be dense If you, taken out the utility pole from the gist permutation interval, displaying the pseudo-span connects the electric pole each other back and forth, abort the single stroke if any delimiter code, a new single stroke from the next telephone pole Open City, strains during congestion, using a utility pole gist permutation, the end points of the section, and displaying a pseudo-span by thinning out the actual span data while holding the branch point.

DETAILED DESCRIPTION OF THE INVENTION
Embodiment 1
As shown in FIG. 5 described in the above-mentioned conventional technology, after having the rectangular coordinates surrounding the feeder, checking the rectangle and the rectangle of the display area, searching for the overlapping feeder and roughly identifying the equipment, In a distribution line diagram display device that searches and displays details that overlap the display area, the spans for each section are displayed as follows.
[0012]
With respect to FIG. 1, first, during the facility data maintenance process, a section generation process (S11) and a point permutation generation process (S12) are performed. In the section generation processing, the figure and name of the distribution facility, that is, section data, switch data, utility pole data, and span data are generated and stored as in the prior art. In the point permutation generation process, a point permutation (point of utility pole / NULL) is set in a section (a span divided by a switch, a set of utility poles).
[0013]
A point permutation is a one-stroke set of telephone poles at end points and branch points. The essential points permutation will be described with reference to the example of FIG. 2 as (1) (3) (5) NULL (3) (6). In other words, proceed with one stroke in the order of (1), (2), (3), (4), and (5). Proceed with 9 ▼ ▲ 8 ▼ ▲ 7 ▼ ▲ 6 ▼. At that time, only end points and branch points are stored in a permutation. NULL in the permutation indicates that the vehicle has started again from the branch point (3) after reaching the end point (5).
[0014]
Then, at the time of the track diagram display processing, after the display target feeder is searched, the degree of congestion of the system facility is determined based on the number of display target feeders (S21). When it is determined that it is not crowded, display processing between the actual diameters is performed (S22), and the line diagram between the actual diameters of the display device is displayed as usual using the utility pole data, the span data, etc. stored in the section generation processing. Display on screen 1. The solid line diagram of FIG. 2 is displayed.
[0015]
When it is determined that the area is crowded, the pseudo-diameter display process (S23) is performed, and the electric poles are sequentially taken out from the set pertinent permutations and displayed on the screen 1 of the display device as the adjacent electric poles as the pseudo-interval. . At that time, when NULL is taken out, the pseudo span that has been continued until then is cut off, and the pseudo span display is newly started from the next utility pole. As a result, (1) (3) (5) line splitting and (3) (6) line splitting are displayed on the screen 1 of the display device. The dotted line in FIG. 2 is displayed.
[0016]
According to the first embodiment, when the scale of display is increased and the system is crowded, the actual span display is switched to the pseudo span display, and the span figure is thinned and displayed while holding down the main points as the sections. It can be displayed at high speed.
[0017]
Embodiment 2
In the distribution line diagram display device for searching and displaying the display object as shown in FIG. 5 above, the span for each section is displayed by the following method.
[0018]
3, during the facility data maintenance process, section data, switch data, utility pole data, span data, and the like are generated and stored in the section generation process (S11) as before.
[0019]
Then, at the time of the track diagram display process, after the display target feeder is searched, the degree of congestion of the system facility is determined by the number of display target feeders (S31). When it is determined that it is not crowded, the actual diameter is displayed on the screen 1 of the display device using the utility pole data, the span data, etc. as usual in the display process between the actual diameters (S32). The solid line diagram of FIG. 4 is displayed.
[0020]
If it is determined that the area is crowded, the utility pole with the switch connected to the section as shown in FIG. 4 using the section data in the pseudo span display process (S33) will be shown in FIG. An inclusion rectangle of a section surrounding 6 ▼ is generated, and a pseudo span connecting the midpoint and the switch-installed utility pole (1), (5), (6) is displayed on the screen 1 of the display device. The dotted line portion in FIG. 4 is displayed.
[0021]
According to the second embodiment, while maintaining the performance of the equipment data maintenance process as in the prior art, when the system is crowded, the display is switched to the pseudo span display, and the span figure can be displayed at high speed.
[0022]
【The invention's effect】
Since this invention is comprised as mentioned above, there exists an effect described below.
(1) When the scale magnification increases and the distance between the display objects increases and the system is crowded, the display between the actual diameters switches to the display between the pseudo diameters (macro display), and the distance between the display objects decreases drastically. The span can be displayed.
(2) In the case of the invention of claim 1, the branch point is the actual utility pole position in addition to the end points, and the graphic skeleton is maintained, so the scale magnification is increased and the middle utility pole is somewhat Even if it is pulled, it is not conscious and no problem occurs.
(3) In the case of the invention of claim 2, since it is not necessary to generate specific display data in advance, the performance of the equipment data maintenance process can be maintained as in the prior art.
