Abstract

A device for representing and/or displaying various process and/or controlled variables for selectable application cases on a display unit, with bar graphs being arranged in respective, predetermined surface elements (A, B, C), with each bar graph, respectively each surface element (A, B, C), having a defined form and/or a defined position on the display. A control unit assembles bar graphs, respectively corresponding surface elements (A, B, C), mosaic-like in a display in such a manner that the resulting bar graph display is matched to a selected application case.

Claims

1. A device for representing and/or displaying various process and/or controlled variables for selectable application cases on a display unit, comprising:

the display unit on which bar graphs are arranged in respective, predetermined surface elements, each bar graph, respectively each surface element has a defined form and/or a defined position on the display; and

a control unit which assembles the bar graphs, respectively the corresponding surface elements, mosaic-like in a display or said display unit in such a manner that the resulting bar graph display is matched to a selected application case, wherein;

a first bar graph of said bar graphs, respectively a first surface element (A), has a predetermined length and a predetermined height, said height of said first bar graph, respectively the first surface element (A), differs in a middle region from the height of said first bar graph, respectively the first surface element (A), in its two lateral, end regions;

said first bar graph of said bar graphs, respectively said first surface element (A), is formed point-symmetrically with reference to a perpendicular bisector;

said first bar graph of said bar graphs, respectively said first surface element (A), has a maximum height in a region at the perpendicular bisector and a minimum height in two lateral, end regions;

a second bar graph of said bar graphs, respectively a second surface element (B), and a third bar graph of said bar graphs, respectively a third surface element (C) both are formed as acute-angled, isosceles triangles;

peaks of said isosceles triangles adjoin the region of maximum height of said first bar graph of said bar graphs, respectively said first surface element (A); and

bases of said two isosceles triangles lie, respectively, parallel to the perpendicular bisector in said two end regions of said first bar graph, respectively said first surface element (A).

2. The device as claimed in claim 1, further comprising:

an input unit is provided, via which a particular bar graph display is determinable for a selected application case.

3. The device as claimed in claim 1, wherein:

by a combination of said first bar graph and said second bar graph, respectively of said first surface element (A) and said second surface element (B), a bar graph (A+B) rising from a left region of the display to a right region of the display is formed.

4. The device as claimed in claim 1, wherein:

by a combination of said first bar graph and said third bar graph, respectively said first surface element (A) and said third surface element (C), a bar graph (A+C) rising from a right region of the display to a left region of the display is formed.

5. The device as claimed in claim 1, wherein:

by a combination of said first bar graph, said second bar graph and said third bar graph, respectively of said first surface element (A), said second surface element (B) and said third surface element (C), a bar graph (A+B+C) rising from the perpendicular bisector of said first surface element (A) to a left region and to a right region is formed.

6. The device as claimed in claim 3, wherein:

in end regions of said individual bar graphs, respectively said individual surface elements (A, B, C), arrow-shaped markings are provided.

7. The device as claimed in claim 1, wherein:

at least one region is provided on said monitor for representing alphanumeric characters and/or symbols.
