<p>PURPOSE:To reduce the size of a control panel by giving a touch to a plant equipment on a plant flow chart displayed on a display means to select the corresponding operation plant equipment and then giving a touch to the operating switch of the plant equipment displayed on the same screen. CONSTITUTION:The measurement signal given from a measuring instrument 1 is synthesized with the image data selected out of a image data storage device 2 via an image selecting keyboard 3 by an image synthesizing device 4. This synthesized image data is supplied to a CRT 5. A touch screen 6 supplies the signal showing the position on a screen touched by an operator to a controller 7. The controller 7 refers to this signal and the image data stored in an image data storage device 2 to display the image data of the operating switch of the plant equipment touched on the CRT 5. The second touch is given to the displayed operating switch and the screen 6 sends the touch position signal. Thus the controller 7 sends the control signal corresponding to said touch position signal to the plant device.</p> |
