Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a supervisory control system for monitoring a plant to be monitored by a graphic display, and more particularly to a supervisory control system for controlling a plant from a graphic screen.

[0002]

2. Description of the Related Art In recent years, a CRT display system for displaying a plant system is often used as an operator interface in a supervisory control system for various plants.

In order to distribute the functions, a dedicated computer system is provided for each function such as a computer system dedicated for operation planning and a computer system for plant monitoring / operation, and these are connected by the same network. , A window is displayed on a CRT by one graphic display system connected to this network, information of each computer system is displayed by each of these windows, and the status of each computer system is displayed only by the screen of this graphic display system. Often be able to monitor.

In this case, in many graphic display systems, in order to monitor / operate the plant, this graphic screen is used as a touch screen, and the operator touches the graphic screen with a button image to control the plant operation. Let

[0005]

However, the above-mentioned conventional supervisory control system has the following problems.

That is, since a program that operates in a computer system for plant monitoring / operation is often created with the operator being aware of the operation of the button image, the touch screen is touched to use the button so that the plant is touched. I am trying to input the instructions for monitoring / operating.

For example, when one motor provided in the plant is turned on / off, a graphic screen 101 is displayed on the graphic screen 101 as an image of an on / off button as shown in FIG. By touching the button image portions 102 and 103, the instruction is transmitted to the motor on / off controller to control the on / off of the motor.

[0008] However, in a program for making an operation plan, that is, a rather clerical program, many are conscious of a pointing input device such as a mouse or a trackball.

For example, the operation plan menu is displayed on the graphic screen 105 as shown in FIG. 5, and the execution order of each menu is determined while pressing the first button of the mouse as shown in FIG. Move the mouse cursor 106 to the place you want to disable as shown in
You can press a button to override the order that has already been determined.

Considering such a case, the graphic display system requires two input devices, a pointing device such as a mouse and a trackball, and a touch screen.

However, depending on the place where the graphic display system is installed for plant monitoring / operation, there is no place to place a pointing device such as a mouse or a trackball. There is a problem that a program that uses a pointing device such as a trackball cannot be displayed or operated.

In view of the above circumstances, the present invention selectively displays either a window dedicated to button input or a window dedicated to pointing device input such as a mouse or trackball on a graphic screen, whereby a mouse or trackball is displayed. It is an object of the present invention to provide a monitoring and control system capable of issuing the same instruction as when using a pointing device such as a mouse or a trackball even in a place where a pointing device such as is not installed.

[0013]

In order to achieve the above-mentioned object, a supervisory control system according to the present invention is a graphic having a window control function, a graphic drawing function and a touch screen function in a network to which a plurality of computer systems are connected. In a supervisory control system in which a display computer system is connected and the status display of each computer system and the input to each computer system are performed by each window of the computer system for graphic display, the program of each computer system is pointing input. When you need, the mouse input dedicated screen is displayed on the touch screen of the computer system for graphic display, the pointing input data is generated based on the touch state of this mouse input dedicated screen, and the pointing input data is generated. It is characterized in that passed to the computer system in need.

[0014]

In the above configuration, when the program of each computer system requires pointing input, the mouse input dedicated screen is displayed on the touch screen of the computer system for graphic display, and the touch state of this mouse input dedicated screen is set. By generating pointing input data based on it and passing it to the computer system that requires pointing input, even in places where pointing devices such as mouse and trackball are not installed,
Give the same instructions as when using a pointing device such as a mouse or trackball.
