Plant information display device

A plant information display device which recognizes a plant state to display plant information necessary to operate instruments constituting said plant, the plant information display device comprising:

• an input unit;
• a region determination unit into which an interest region and a deformation condition in said plant are fed using said input unit, said region determination unit specifying a deformation target region based on said interest region and said deformation condition supplied from said input unit;
• a region division unit which divides a drawing into a plurality of regions based on said deformation target region specified by said region determination unit, said region division unit performing management while said deformation target region and a non-deformation target region are divided;
• a drawing distortion unit which separately deforms said deformation target region and said non-deformation target region;
• a drawing output unit which supplies said deformation target region and said non-deformation target region as output data of said drawing, said deformation target region and said non-deformation target region being distorted by said drawing distortion unit;
• and
• a display unit which displays said output data supplied from said drawing output unit, wherein:
• when said drawing and an additional object display region in which a plurality of screens including an operation setting screen of said instrument and an instrument parameter display screen necessary for plant running are displayed while overlapping each other, said drawing distortion unit extracts pattern elements included in said additional object display region based on said additional object display region, and sequentially moves said extracted pattern elements to an outside of said additional object display region in order from said pattern element existing near a center of said additional object display region;
• when display is not accommodated in a display screen of said plant information display device, said drawing distortion unit divides said non-deformation target region into a plurality of regions, said drawing distortion unit moving said plurality of regions into which said non-deformation target region is divided and changing a scale thereof such that topology is retained between regions adjacent to each other with respect to said deformation target region and said non-deformation target region;
• and
• when a discontinuous portion is generated between the regions adjacent to each other due to said distortion by said drawing distortion unit, said drawing distortion unit uses, based on logical connection information of topological information, said pattern element to perform interpolation connection between said regions of said plurality of regions into which said non-deformation target region is divided, and between said region of said plurality of regions into which said non-deformation target region is divided and said deformation target region, such that topology similar to that of said original drawing is retained.
