Since this is often done while coordinating with the field, when displaying the power distribution system diagram on a graphic CRT display device, it is necessary to take topographical features and respond to them.・Display the approved plan by directly matching the power distribution system diagram and road map. However, by adjusting the display scale, the range of the displayed street map has become wider, and the line segments and layouts representing the streets have become wider. If the line segments representing the edges are very close to each other, the display becomes distorted, making it difficult to see all four sides.

There are some tasks related to KM that correspond to streets and do not require a ratio display, and in such cases, the street display becomes a hindrance, making it difficult to recognize the system status and making it difficult to understand the main purpose. It is impossible to carry out system monitoring work efficiently.

This is the ninth step in which a street map is developed into bits corresponding to its color information, and similarly, it is developed as a combination of on/off bits according to its color information.

In the graphic CRT display 11 resegment buffer 51 shown in FIG. 3, a first look-up table 7 and a second look-up table 7 shown in FIG. The first lookup table 7 is bit plane divided by 1. ≠2 for an address that includes a signal corresponding to graphical information, for example a signal of "1", in each bit of a, bit plane≠3. Regardless of the bit of ÷4, Pidbunone+1. A display color is defined corresponding to the combination value of ON/OFF of the bit of φ2. For addresses other than n, bitplaner 3. The display color is defined in accordance with the on/off range of bits 4 and 1-'. The process is determined by the combination of beam outputs. If the l-th lookup table 7+ks is divided into four groups I to ■, with one group of 4 stages, for groups l to ■, bit planes +1. Display colors are defined corresponding to the combination value of on/off of the +2 bits. Regarding group ■.

This is a portion corresponding to a point where the power distribution system diagram is not drawn on the frame buffer, and the display color is defined corresponding to the combination 1 of bit planes 3 and +4 of bits θ on and off. The second lookup table 7 includes the bitplanner 1. For addresses containing a signal corresponding to graphical information, for example "1", in each bit of
For addresses other than VC, the outputs of R, C), and B are also set to 0, and black (W scenery) is defined as the display color.

It is a 1L7t table cutting part provided at t, and 5xv
A lookup table with multiple references between the lookup table 7 and the lookup table 7 of -J2 is cut.

The operation of the above embodiment will be briefly described.

In the system shown in FIG. 3, the display 6H from the display processor 4 causes the segment buffer 5. One of the power distribution system diagrams and street maps stored in the map is designated as a display target and expanded to a frame buffer 6 in an area 7. Here, regarding the power distribution system diagram, bit plane ÷ 1 is calculated according to the color information. Bit expansion n to φ2,
Regarding the street map, Bit Planer 3. Bit expansion is performed so that ≠4. Then, the table switching section 13 stores the first lookup table 7, 9, and performs a raster scan on the frame buffer 6. Lookup table 7 is referenced as the off combination address.

As a result, as shown in FIG. 2, the power distribution system diagram and corner diagram are displayed on the screen, but the information is expanded to bit plane ÷ 1° + 2, and the information is expanded to bit plane + 3. Expanded to Hana 4 n
Since the lookup table 7 of the engineering MC11 is specified, which is preferentially displayed for the information m, the power distribution system diagram is displayed above the street map.

After that, make a cut in the table cutter 9 holder 13 and call it to the lookup table 7 of the conduit 2.
When raster scanned, in the second lookup table 7, frame, bitplane≠1. ◆For addresses where the figure 1 acknowledgment is not selfish in 2, an ambiguous black color is displayed, which is the bit plane 4P3.
The nfC circuit diagram drawn at ≠4 is displayed in color and is erased from the vCg plane shown in FIG. 2, resulting in an n-th state. (When the table cutter 13 switches to the lookup table 71 of the ditch 1, the friendship road 1.
81, it is displayed again at the bottom of the power distribution system diagram.

Effects of the Invention Two aspects of the present invention include a method for deleting only the street map from the superimposed display state of the power system diagram and the street map;
Since the power system diagram is conspicuous, the system status can be easily recognized. Then, after checking the system status for the fourth time, we will respond to the site.
If the current task is not carried out, the street map can be redisplayed, and as a result, the system monitoring task can be carried out more effectively.

Secretly divide the power system diagram and street map into nest 1 bit plane group and second bit plane group, respectively, and create ``Power system diagram?'' - Since the street map, which is the accompanying information, is displayed in advance, it is not displayed above the power distribution system diagram, and division of the power distribution system diagram can be prevented. Moreover, the erasure/redisplay processing is performed by the control processing of lookup table decompression without expanding the bits into a 7 frame buffer. Since it is much faster than , erasure/redisplay can be performed at high speed.
