Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a machine Rg selection display method in a monitoring/control system, and the display of the symbol mark of a device on the CR1 screen is different depending on when a device failure occurs and when the device is selected. The purpose of the present invention is to enable selection control operations to be performed without error even at times.

Generally, in monitoring and control systems such as video management, the symbol marks of multiple devices to be selected and controlled are displayed on the CR1 screen of the central monitoring station. Depending on the status of each device, it will be red if it is normally on.

If they are off, they will be displayed in green.

When the operator uses the CR1 screen to select and control S devices, when the operator selects the device he or she wishes to control, the symbol mark on the CR1 screen of the selected device flashes in the color indicating its current status. , indicates that the device in question is selected, and then operates the ON/OFF switch 77 on the control desk of the central monitoring station to output a control signal to turn ON/OFF the device, and the device is controlled normally. In this case, the symbol mark of the device on the CR1 screen will be reversed to the color indicating the state after control, that is, the on state for large control, and the off state for off control, and will stop blinking, indicating that control is complete. .

By the way, in this type of device selection display method, when a failure occurs in a device, the symbol mark on the CR1 screen of the device also blinks in the color indicating the current status, similar to when selecting the device as described above, so the symbol mark blinks. It is difficult to distinguish whether this is due to an operator's selection operation or a failure of the equipment, and for this reason conventionally, when a failure occurs, selection control of the equipment cannot be performed.

However, according to the device selection display method described above, in the event of an emergency such as a failure occurring, it is necessary to temporarily stop the flashing of all failure points, call up the necessary screen again, and perform selection control, which is very time-consuming. There are such inconveniences.

Here, the display of the symbol mark of the equipment by CRT,
One possible method is to slow down the blinking when high speed 2 is selected when there is a failure, as is done with graphic panels, etc., but in this case, it is necessary to have two blinking cycles, and with ordinary CRTs, It is technically difficult to display images with different blinking cycles, and a new CRT must be manufactured.

This invention was made with the above points in mind, and
The symbol marks of a plurality of devices to be selected and controlled are displayed on the CI'LT screen in a color corresponding to the status of each device, and when each device is selected, the symbol mark of the selected device is displayed to indicate a failure. An object of the present invention is to provide a device selection display method characterized by displaying in a color or brightness other than the state display, which is different from that at the time of occurrence.

Therefore, according to the device selection display method of the present invention, C.
The symbol mark of the device on the RT screen can be made different from that at the time of failure when the device is selected, and can be displayed in a color or brightness other than the status display, so even when a failure occurs, it is possible to distinguish between the failed device and the selected device. This makes it possible to perform emergency selection control without having to perform an operation to return to the failure screen as in the conventional case, and the selection control operation can be performed without fail.

Next, the present invention will be explained in detail with reference to drawings showing one embodiment thereof.

First, Figure 1 shows the screen of the CRT (1) installed in the central control station, and shows the symbol mark of the circuit breaker (2), the symbol mark of the disconnector on the regular side, the tranne, and the circuit breaker (3).
, (4) , (5) , Each symbol mark of standby side disconnector, transformer, and circuit breaker (3)', (4)', (5
)' and the symbol mark (6) of each line network are displayed in a state where they are connected in a single line system.

FIG. 2 shows the operation console (7) of the central control station, which includes a numeric keypad (8) for inputting equipment numbers, etc., a selection key (9) for selecting a designated equipment, and a screen display key al. It is provided with an off operation key aυ that turns off (off operation) the selected device, and an on operation key Q (on operation) that controls the selected device (on operation).

Each symbol mark on the -C, RT (1) screen will be displayed in red if it is on and green if it is off, depending on the status of each device. The symbol on the device will automatically start blinking in the color that indicates its current status.

Next, when selecting and controlling any device, use the operation console (7)
After specifying the device you wish to control using the numeric keypad (8), operate the selection key (9) to select the device.The symbol mark of the device will change to magenta (if it is on) depending on the state at the time of selection. If it is in the off state, it starts blinking in cyan (green + blue), indicating that it is currently selected. Then, when a control signal is output to the selected device by operating the OFF operation key a → or the ON operation key (A) on the operation console (7), if the device is controlled normally, C
The symbol mark of the device on the screen of I't T f, 1) changes to a color indicating the state after the control and stops blinking.

Therefore, according to the above embodiment, the symbol mark of each device on the screen of the CRT (1) can be made to blink in different colors depending on when a failure occurs and when it is selected. It is possible to easily determine whether it is a function or a selection, and the selection control operation can be performed without fail even in the event of an emergency such as a failure, without having to return to the failure screen as in the past. Additionally, the inconvenience of having to create a new CIILT can also be avoided.

In addition, in the above embodiment, the symbol mark of the selected device blinks while changing the status display color, but the present invention is not limited to this, and the brightness of the symbol mark of the selected device may be changed. . In other words, the symbol mark of the selected device is displayed in red or blue to indicate its current status.
In addition, it may be displayed at a lower brightness than the normal state display brightness to indicate that it has been selected.

Further, the symbol mark of the selected device may be displayed blinking in a color other than the status display color, for example yellow, and the status of the device at the time of selection may be displayed in text. In this case, the device selection is limited to one point, so CRT
(1) Provide a place to display the status of the selected device on the screen, such as the bottom line of the screen, and display the status when the device is selected.
It is sufficient to display the characters as N, OFF, run, or stop.
