Abstract

Without using any drawing command of a commercially available OS or library, screen information that will be screen elements has preliminarily been registered in a screen information database, and based on a touch position information detected by a touch position detecting section, a request control of a display screen or generation of a plant operation information is executed, as well as a registered screen information is fetched from the screen information database to generate a display screen and a process data of a plant that is linked to the display screen is read via a network.

Claims

1. A plant monitoring control system comprising:

a visual display unit (VDU) terminal displaying an operating state and process amount information of a plant as a monitoring control screen;

a touch position detecting section detecting a touch position on a display screen using a touch panel located in opposition to said display screen of said VDU terminal;

a plant monitoring control unit including a screen information database in which a database of screen display information of a monitoring control screen to be displayed on said display screen of said VDU terminal has preliminarily been registered, wherein the plant monitoring control unit is configured to

perform a drawing process for displaying an operating state and process amount information of a plant on said display screen of said VDU terminal,

generate an operation signal of a plant using a screen information having preliminarily been registered in said screen information database and touch position information to be detected by said plant monitoring control unit,

edit the registered screen display information,

execute a request control of said display screen or generation of a plant operation information based on touch position information detected by said plant monitoring control unit,

fetch a registered screen information from said screen information database to generate a display screen, and

read a process data of a plant that is linked to said touch position information display screen via a network.

2. The plant monitoring control system according to claim 1, wherein in said screen information database, screen elements to make up a display screen and graphics of said screen elements have preliminarily been registered.

3. The plant monitoring control system according to claim 1, wherein in the case of the presence of a request of an operation screen from another plant control unit in connection via a network, request information is fetched via said network and an operation screen based on the request is displayed on said display screen.

4. The plant monitoring control system according to claim 1, wherein in the case that a touch position information detected by said plant monitoring control unit specifies an operation command of a plant, a screen operation information is generated at the plant monitoring control unit using said screen information database, and an operation command is transmitted to said plant monitoring control unit via said network.
