Abstract

(57) [Summary] [Purpose] To obtain a plant monitoring and control device that enables the operator to easily understand the monitoring control contents of each operator from a CRT other than the CRT used by the operator. [Configuration] Each CRT of a plant monitoring and control device using a CRT display is provided with a function capable of displaying a list of screen names / screen numbers currently displayed on all CRTs upon request.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a plant monitoring control device using a CRT display.

[0002]

[Prior Art]

 FIG. 3 is a diagram showing a conventional plant monitoring control device using a CRT display. In the figure, 1 is a control panel used by an operator, 2 to 7 are CRT displays for plant monitoring control mounted on the control panel 1, 8 -13 is a request panel for calling the screen of the CRT displays 2-7 for plant monitoring control, 18 is a console for the operator's supervisor, 14 and 15 are CRTs attached to the console for supervisor 18 (shown in 2-7) All screens can be displayed.), 16 and 17 are request panels for CRTs 14 and 15, 19 is a computer for driving CRT displays 2 to 7 for plant monitoring and control, CRTs 14 and 15, and request panels 8 to 13, 16, and 17. is there.

Next, the operation will be described. The computer 19 inputs information (process value, equipment status, alarm signal, etc.) necessary for plant monitoring control, and displays this information on the CRTs 2 to 7, 14 and 15 every moment by real-time operation. The CRT can switch and display a plurality of screens, and a screen name and screen number are attached to each screen to identify each screen. The request panels 8-13, 16 and 17 can be displayed on the CRT 2-7 by selecting the required one from multiple screens.

[0004]

[Problems to be solved by the device]

 Since the conventional plant supervisory control device is configured as described above, a plurality of operators perform supervisory control using different CRTs, but what kind of screen each operator uses and which supervisory control is performed? There was a problem that it was necessary to orally confirm whether or not the CRT moved to a certain position in order to know if the CRT was being performed.

The present invention has been made in order to solve the above problems, and obtains a plant monitoring / controlling device in which the CRT screen used by each operator can be known by another CRT. With the goal.

[0006]

[Means for Solving the Problems]

 The plant monitoring and controlling apparatus according to the present invention has a computer provided with a function of displaying a list of screens currently displayed by all CRTs on the CRT being displayed.

[0007]

[Action]

 The plant supervisory control device in this invention can display the screen currently displayed by all CRTs on the CRT being displayed by the computer and know which screen is currently being used by another CRT. Therefore, it is possible to easily understand what kind of monitoring control is being performed by another operator by using a nearby CRT.

[0008]

【Example】

 Example 1. Embodiment 1 of the present invention will be described below with reference to the drawings. In FIG. 1, 19 is a screen displayed on CRT 15 (same for 14), and 20 is a list of CRT display screens.

Next, the operation will be described. The CRT display screen list display 21 is displayed on the CRT screen 20 by an operation from the request panel 17 (or the request panel 16 when displaying on the CRT 14). This list display may be displayed in a multi-window on the screen being displayed on the CRT screen 20, or may be displayed in an area not used on the CRT screen 20. While the operator supervisor monitors the plant using the CRT 15 (or 14) on the console 18, a request for a list display of the screen names and screen numbers currently displayed on the CRTs (2 to 7) used by each operator. By doing so, it is possible to know at any time, and it is possible to easily understand what kind of plant monitoring control each operator is using the CRT.

Example 2. In the first embodiment described above, the case where the operator supervisor knows the CRT screen used by each operator by the CRT 15 (or 14) has been described. However, as shown in FIG. , It is possible to know which screen is used by the operator who is using the CRT 7 by the list display 23. Similarly, the operator who is using the CRT 7 can see which screen is being used by the operator who is using the CRT 7. You can see if you are using the list display 25. In this way, operators can easily comprehend each other's monitoring and control contents, and cooperation between operators becomes easy. Any combination of CRTs is possible.

[0011]

[Effect of the device]

 As described above, according to the present invention, the list of display screens of all CRTs can be displayed on each CRT, so that the operator supervisor can easily understand the monitoring control contents performed by each operator. In addition, the operators can easily understand each other's monitoring control contents, which facilitates the cooperation of the operations of the operators.
