In the following description of the present invention, application to a power system, particularly a power distribution system, will be described as an example.

C0 conventional technology Graphic CRT display devices have traditionally been CAD-based.

Mainly creating figures in fields such as CAM and CAE.

Although it is often used in offline work called modification,
Recently, the field of use as a terminal device for online systems has been increasing.

For example, in a centralized power distribution system monitoring and control system, a central computer serving as a master station processes a lot of information from a group of slave stations, and Oma's visual perception, judgment, and creativity are used to process this information. A graphical CRT freshwater device is provided that interacts with the comviator to enable rapid, accurate on-line processing.

In this centralized monitoring and control system, the graphic CRT display device serving as the terminal device is required to have the following two points in terms of function and performance compared to conventional ones.

(1) High-speed fresh water: Good responsiveness is an essential condition for an online system, and the process from display request to completion of installation must be performed quickly, and various display changes must also be performed quickly.

(2) Wide area support: Since the online system operates on equipment installed in a wide area, it must support a wide display area and be able to display the necessary range according to display requests.

In order to meet these demands, a system configuration called an intelligent terminal type has been adopted as a graphic display system.

As shown in FIG. 3, in this system, a graphic CRTi display device 1 having a computer is used as a terminal side, and a host computer system 2 in a central supervisory control 41 and scissor station is connected to this terminal side via a communication line. Using this host computer system 2 as a master station, the slave stations collect various types of monitoring information in real time, display necessary display information on the graphic CRT display twiVcs, and receive commands from the graphic CRT display device 1 and the host computer. A centralized monitoring control system is realized by a configuration in which control information automatically processed by the system 2 is transmitted from the host computer system 2 to the slave station side.

In this configuration, a distributed processing method is used in which the host computer system 2 performs a large amount of arithmetic processing or data processing, and the computer in the terminal-side graphic CRT display 1 performs display processing. The load on the host computer system 2 is also reduced while improving the responsiveness of the host computer system 2. Graphic information processing in the configuration shown in FIG. 3 will be explained in detail below.

The graphic CRTfi display device 1 has a CRT monitor 6 that performs graphical drawing using a raster scan display method, and the graphic information stored in the display processor 4t-system 5 has a logical relationship as shown in FIG. , the individual graphic elements located at the lowest level (data type 1 display position 0 display color etc. that specifies the display figure) SD, and these graphic elements S
The shape is located above D! ! It is configured into a tree structure by attribute elements SP that define individual attributes (visible attributes, detected attributes, etc.).

From the graphic information stored in the segment buffer 51, graphic information in a required range (a rectangular area determined by coordinate values) is cut out. For this cutting process, a matrix arithmetic processing unit 5t that performs parallel translation and rotational transformation of the displayed figure, a clipping processing unit 51 that removes a portion that extends beyond the display frame of the cR'r monitor 3, and the like are prepared. The line segment of the cutout nine figure information is shallowly indicated i
From t (coordinate position), the corresponding 7-frame software 6
A digital differential analysis (DDA) processing unit 54 is provided which develops the on/off information of the upper bit.

Physically, the frame buffer 6 is a memory 69 that has bits that correspond one-to-one to each pixel VC on the screen of the CRT-e=p6, and has multiple bit planes for color display, and a look-up table 7. Use to determine the fitted color.

Returning to FIG. 3, the host computer system 2 uses the host combination 2-8 as a control center and divides the data that has been subjected to graphical information processing as one of the processing functions of online processing into a suitable format and stores it on a magnetic disk, etc. Auxiliary storage device 1lt
9, and the graphic information line surface 1G, 1 in the range required from the graphic CRT fresh water device 1.
1. Graphic C through the communication rjA line of transmission line 12
The R'lt display device 1rc transmits the data, and the CRT display device 1 receives the data and stores it in the segment buffer 51.

By the way, a power system diagram, for example, a power distribution system diagram, is shown in graphic C.
When displaying on an RT display device, a street map is superimposed on the display in order to facilitate communication with the field, but when performing operational work using such a display, the following information regarding the operation of underground equipment switches should be observed. There were some problems. The onboard equipment has multiple switches inside, but it is compact in size because it is installed underground (4h7/b). In actual operation work, each switch in the underground equipment is the target of operation, but if each switch is displayed on the screen, it becomes impossible to correspond to the street map, and operations are performed while corresponding with the site. It becomes difficult to go. Therefore, conventionally, when displaying a power distribution system diagram, the symbol t- for underground equipment is displayed, and for instructions on internal switches, the screen can be switched to fc, or other public equipment I. However, with this method, it is difficult to determine how the underground equipment is located in the power distribution system, and the opening/closing method is difficult to determine. Since the operator has to operate the equipment, the operability is reduced and it is difficult to quickly respond to various operational tasks, such as the occurrence of an accident.

D1 Problems to be solved by the invention The present invention was made against this background,
For example, when performing operational work using the power system diagram display, it is possible to efficiently operate the switches of underground equipment, and it is a graphic that allows quick response to various operational work, typified by the occurrence of an accident. The purpose is to provide a shallow water device.
