Register video information to (9n).

Furthermore, as shown in FIG. 5(a), as a device information layer 110, for each device symbol registered in the basic side station 18), the device symbol lvA and the response data from the device of the device symbol are displayed. A string of characters and numbers B, the device name of the device symbol C1, a status name D that represents the ON, OFF, etc. status of the device of the device symbol, and a measured value to represent the rated value or measured value of the device symbol. In addition to registering display items (la) such as E and unit F, in addition to these, as shown in FIG. ib) and the equipment number item (Ic) provided for each function identification code.

At this time, as the video information corresponding to the display item (la), as shown in FIG. is the * symbol, and what is the number of digits of the measured value E? The unit F is registered in each predetermined layer among the basic video layers (91) to (9n) in such a manner that the number of characters of the unit F is set to 8 symbols and a period symbol indicating a decimal point.

In addition, the J18 level 1 or 2 level kanji set database and other databases required when actually displaying the instrumentation monitoring and control screen can be stored on a CRT display (4
) shall be prepared on the side.

Next, CR the power system diagram as the instrumentation monitoring and control screen.
When actually displaying the power system diagram on the T151, when a screen display of the power system diagram is requested by key operations on the keyboard of the CRT' display (4), a screen display request command is issued from the CPU (61) to the host computer (31). A request is made to the host computer (31) for data necessary for screen display, and based on this request, the host computer (3) collects the ON/OFF status of each device and measurement data.

While the host computer +31 is collecting data, the CPU (51) saves the basic image as shown in FIG. will be displayed, waiting for a reply such as data from the host computer (3),
When a response command for the screen display request command is issued from the host computer [3] to the CP TJ (61) and there is a reply such as data from the host computer (3+), based on the reply data from the host computer (31), the CP

Furthermore, when a change occurs in the status or measurement data of each device, a status change notification command is issued from the host computer (3), and the CPU (61)
If the change in status is on the screen currently displayed on the CRT +51, the display quality reception processing instructed by the data of the status notification command is performed, and if the change is unrelated to the screen currently displayed on the CRT+51, the status change notification is Command data is ignored.

In addition, when CP TJ (Q) is displayed on the CRT +51 screen, database (7) and other databases necessary for display 9 are linked, and the specified characters are displayed in the power system diagram shown in Figure 6. and numerical values are added and displayed.

In addition, when it becomes necessary to change the display attribute processing content itself, there is no need to change the processing program on the host computer side as in the past, and the database (7.
All you need to do is change or add the basic video layer in step 1.

Therefore, according to the embodiment, when changing the display attributes of symbols in the power system diagram, which is the instrumentation monitoring and control screen, the host computer +31 inputs the device number into the CPU (61) of the CRT display (4). By simply inputting the data and function identification code data as appropriate, the necessary video information is selected from the database (71 basic video layers (91) to (9n)) and combined with the basic image, so the display attributes can be changed. Host computer (3) to avoid changes
The processing performed by the host computer (3) can be significantly reduced, and the burden on the host computer (3) can be reduced compared to the conventional method.

In addition, even if it becomes necessary to change the display attribute processing content itself, it is only necessary to change or add the basic video layer in the database (71), and the host computer
There is no need to change the processing program on the 31 side.

In the above embodiment, a case has been described in which a power system diagram is displayed as an instrumentation monitoring and control screen, but the present invention is not limited to this, and a case where another instrumentation monitoring and control screen such as a road system diagram in a traffic monitoring facility is displayed. However, the present invention can be implemented in the same manner.
