Abstract
Abstract A drawing management device for managing the drawing of an entire facility, such as a water supply facility, as digital information. This device includes a unit for storing drawings with priorities obtained by separating the entire facility drawing into sub-facility drawings located at plural levels, a selective display designating unit for displaying a desired sub-facility drawing obtained by selecting the number of levels considering the priority from the storing unit, and a display unit for displaying the desired sub-facility drawing in response to the signal from the selective display designating unit. By suitably selecting a desired level considering the priority, only a necessary and sufficient facility drawing can be displayed swiftly.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
212 words
A drawing management and display device for displaying digital information of a system drawing, showing an entire system having a plurality of information items, within a desired display time, said drawing management and display device comprising: a means for referencing a total display time required for displaying said system drawing, for determining a plurality of different display time priority levels each having a different display time which is shorter than said total display time, and for storing said system drawing as a plurality of sub-drawings each representing the same area of said system drawing and having a different number of said plurality of information items which make up said entire system such that display of each of said sub-drawings can be accomplished within a different said different display time, said sub-drawings being stored with respective priorities each of which represents an ability to display the sub-drawing within a different said different display time; a selective display designating means for automatically selecting one of said sub-drawings stored in the storing means on the basis of the priority thereof in order to accomplish display within said desired display time; and a means for displaying selected said sub-drawings within said desired display time in response to said selecting operation of said selective display designating means.
Claim 2
Dependent Claim
212 words
A drawing management and display device for displaying digital information of a system drawing, showing an entire system having a plurality of information items, within a desired display time, said drawing management and display device comprising: a means for referencing a total display time required for displaying said system drawing, for determining a plurality of different display time priority levels each having a different display time which is shorter than said total display time, and for storing said system drawing as a plurality of sub-drawings each representing the same area of said system drawing and having a different number of said plurality of information items which make up said entire system such that display of each of said sub-drawings can be accomplished within a different said different display time, said sub-drawings being stored with respective priorities each of which represents an ability to display the sub-drawing within a different said different display time; a selective display designating means for automatically selecting one of said sub-drawings stored in the storing means on the basis of the priority thereof in order to accomplish display within said desired display time; and a means for displaying selected said sub-drawings within said desired display time in response to said selecting operation of said selective display designating means.
