Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention shows the state of plant equipment in C
The present invention relates to a screen search method of a monitor control device that monitors a display such as an RT.

[0002]

2. Description of the Related Art In a supervisory control device having a display such as a CRT, a graphic display screen for systematically displaying the status of the equipment and a bar graph display for displaying the measurement values as a screen for displaying various equipment statuses of the plant equipment. It has a screen and a trend display screen that displays past data of measured values in a polygonal line. In the conventional supervisory control device, a method of displaying a screen of a target system on the display by selecting the type of the display screen in a menu format as a method of displaying the detailed screens forming the respective display screens. There is. FIG. 4 shows an example thereof. First, when a graphic display screen is selected from various display screens in the main menu M1, a graphic display screen menu M2 is displayed, and then a special display is selected from the graphic display screen menu M2. When the substation is selected, the graphic display screen M3 of the extra high voltage substation is displayed, and the target screen is displayed on the display. In addition, on the bar graph display screen, a panel divided for each system as an overview panel is displayed on the screen, and when the panel of the system to be viewed is selected, the bar graph display screen of the selected panel is displayed. There is a way.

[0003]

In the above conventional method,
When an operator wants to see the state or measured value of a certain facility and knows in advance which system the target facility belongs to, selecting the system screen from the menu screen will The screen containing the equipment is displayed and you can check the status and measurement values of the equipment, but if you do not know which screen the equipment belongs to, or you forget it. in case of,
You must find the target screen by checking each screen displayed on the menu screen one by one. Also, when the amount of equipment to be monitored and controlled is small, the number of selection screens displayed on the menu screen is small, and even if you check each screen one by one, the work time is short, but There is a problem that as the number of devices increases, the time for checking the selection screen in the menu screen becomes longer. Therefore, the present invention, when trying to see the state or measured value of the target equipment, even if it is not known in advance which screen the equipment belongs to,
A method for displaying a target screen in a short time without checking each selection screen in the menu screen one by one.

[0004]

According to the present invention, data of a screen for displaying the state of plant equipment and the name and symbol of the plant equipment are stored in advance in a storage device of a supervisory control device, and a display such as a CRT is displayed. Provide a search screen to enter the name and symbol of the plant equipment in, and enter the name or symbol of the plant equipment you want to search from the search screen, the screen that contains the information related to the equipment to be searched from the data in the storage device Search and display on the display.

[0005]

[Function] As described above, even if you do not check each screen from the menu screen, you can search for the target screen in a short time by entering the name or symbol of the equipment you want to search from the search screen. be able to.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a block diagram of a supervisory control apparatus 1 showing an embodiment of the present invention. In FIG. 1, a computer 2 having a storage device 6 monitors and controls the plant equipment 8 via an interface circuit 7 using a display 3, a keyboard 4 and a mouse 5. The display 3 may be a CRT, a plasma display, a liquid crystal display or an EL display as long as it can display characters and graphics, and the keyboard 4 and the mouse 5 also move the cursor on the screen of the display 3 to display characters. Any device that can input can be used.

In the storage device 6 of the computer 2, the names and symbols of the processes to be monitored and controlled by the plant equipment 8 are registered in advance. FIG. 2 shows an example of the input / output item table 9 of the plant equipment 8. The input / output item table 9 has items such as equipment name P1, item name P2 and symbol P3, and the equipment name P1 is the location of the equipment. Item that represents, item name P
2 is the name of the equipment, and symbol P3 is for registering the symbol representing the equipment. In addition, a graphic display screen that systematically shows the processes of the plant equipment 8, a bar graph display screen that shows process measurement values as a bar graph, a trend graph display screen that displays process measurement values as a line graph in time series, equipment The device status display screen that displays the device status in a list, the display screen such as the measurement display screen that displays the measured values of the process, and the No. for each type of these display screens. 1, No. A menu screen with a series of numbers, such as 2, ..., Is registered. Further, the equipment name P1, the item name P2 and the symbol P3 of the input / output item table 9 are displayed in relation to which screen among the display screens such as the graphic display screen, the bar graph display screen, the device status display screen and the measurement display screen. A database associating whether or not there is created in the storage device 6.

Further, the computer 2 has a facility name P1,
A search screen 10 for searching which display screen the item name P2 and the symbol P3 are included in is provided. FIG.
An example of the search screen 10 is shown in (A). On the search screen 10, the equipment name input field S1 for inputting the equipment name P1, the item name input field S2 for inputting the item name P2, and the symbol P3.
It has a symbol input field S3 for inputting. The operator enters equipment name P1 and item name P2 in each of these columns S1, S2, S3.
After inputting and the symbol P3, the computer 2 is instructed to start the search.
