Among these units, the attribute creation registration / correction processing unit 36 and the graphic attribute combination processing unit 38 serve as attribute information updating means, and the drawing search / update processing unit 44 serves as a graphic updating means and graphic information extracting means. Reference numeral 42 denotes a graphic designating means, an attribute information time search processing unit 48 and an attribute search processing unit 5
0 is a corresponding graphic emphasis processing section 46 as attribute information extracting means.
Are respectively configured as display control means.

On the other hand, the display screen of the display 18 is divided into a drawing display area 52 and a mouse operation icon area 54. In the drawing display area 52, an image relating to the facility drawing is displayed, and in a window 56, attribute data ( Attribute information) is displayed. In the mouse operation icon area 54, for example, an index diagram search icon area 58, a drawing read icon area 60, an attribute creation icon area 62, and the like are set as function selection icons.

In the above configuration, the operator operates the mouse 2
2 to move the cursor CU to a function selection icon displayed on the screen of the display 18,
When the "drawing drawing" icon area 60 is designated, in response to the designation of the mouse 22, the CPU 10 searches the file device 12 for the designated drawing data (graphic data and its attribute data). The drawing data is temporarily stored in the main memory 14. The drawing data temporarily stored in the main memory 14 is edited by the display editing processing unit 40 in accordance with the effective display coordinates which are the display area of the display 18. Then, the designated facility drawing is displayed on the screen of the display 18 based on the edited data. By displaying the image related to the facility drawing on the screen of the display 18, the operator can know the contents of the target drawing. At this time, when it is necessary to grasp a detailed portion, the designated figure is enlarged and displayed. For example, the user moves the cursor CU by operating the mouse 22, sets an arbitrary rectangular area on the screen, specifies the diagonal ends of this area, and enlarges the figure in the specified arbitrary area by an arbitrary magnification. To enlarge or reduce. The enlargement or reduction processing is performed by the CPU 10 performing enlargement / reduction editing of a part of the relevant drawing data stored in the main memory 14.

Next, when searching for a target drawing,
When the operator operates the mouse 22 and selects the icon area 58 of "index diagram search", the operation input processing unit 34 is started in response to this operation, and the operation content is selected by the operation input processing unit 34. The index diagram display processing unit 34 operates according to the selection result. The index diagram display processing unit 32 searches the index diagram data registered in the main memory 14 in advance, and outputs the search result to the display editing processing unit 40.
The display edit processing unit 40 displays the index diagram on the screen of the display 18 after editing the searched index diagram data.
In the index diagram, figures such as main roads, railways, and administrative boundaries are displayed so that the entire target area can be grasped. Thus, the operator can search for the target drawing from the index drawing.

When a history related to a specific figure in a drawing is examined, an arbitrary figure on the drawing is selected by operating the mouse 22. In order to search for attribute data related to this figure, the attribute search processing unit 50 performs a search. Upon activation, the attribute search processing unit 50 searches the attribute file 30 for attribute data related to the specified figure and extracts it. After the extracted attribute data is determined by the attribute information time search processing unit 48 to be the attribute data of the latest time, it is edited by the display editing processing unit 40. Then, the contents of the edited data are displayed on the window 56 as attribute information.

On the other hand, when the registration time range of the attribute data is designated from the keyboard 20, the designated attribute data is retrieved from the attribute file 30 by the process of the attribute retrieval processing unit 50. The attribute information extracted by this search is determined by the attribute information time search processing unit 48 as to whether or not the attribute data is attribute data in the corresponding time range. Thereafter, the display editing processing unit 40 performs display editing on the attribute data, the corresponding graphic emphasis processing unit 46 executes processing for highlighting the corresponding graphic, and the display-edited attribute data is displayed in the window 56. You. At this time, if there is no corresponding graphic in the attribute data corresponding to the graphic data due to the deletion of the graphic data, the processing of the attribute information position search processing unit 42 is performed so that the corresponding position of the deleted graphic data can be specified. A past position symbol is generated at the position coordinates (X, Y) of the graphic data included in the attribute data, and the corresponding position is clarified by the position symbol.

Next, a processing method for registering time information relating to attribute data will be described. First, when creating attribute data corresponding to graphic data, the mouse 2
When the icon area 62 of “attribute creation” is selected after the corresponding figure is designated by the operation 2, the input list of the corresponding attribute data is displayed in the window 56 by the processing of the attribute creation registration correction processing unit 36. At this time, the information of the window item is input from the keyboard 20. Further, a creation time (generation time) of the corresponding figure is input. The attribute data input at this time is temporarily stored in the main memory 14 and then registered in the attribute file 30. At this time, the attribute data and the corresponding graphic are associated with each other and combined by the processing of the graphic attribute combining processing unit 38, and the combined information is stored in the attribute file 30 and the drawing file 28, respectively.

On the other hand, when deleting a designated figure in the facility drawing, the designated figure is designated by operating the mouse 22, and the designated figure is deleted. At this time, the graphic data relating to the specified graphic in the drawing file 28 is deleted. However, the time data (time information) of the attribute data related to this figure is updated to the time data at the time of updating. That is, even if the graphic data relating to the specified graphic is deleted and updated, the position data (position information) indicating the position of the graphic on the drawing and the time data (time information) among the attribute data related to the graphic are stored. It is in. Further, when the graphic data is deleted, the position of the graphic data on the drawing becomes indefinite, so that the position coordinates (X, Y) based on the position of this base point with an arbitrary point of the deleted graphic as a base point. This is stored in the attribute file 30 in association with the time information at the time of updating the figure.

Next, when examining the history of the designated drawing among the facility drawings displayed on the display 18, it is necessary to input the time information corresponding to the updating of the drawing to search for the update time of the designated drawing. it can.
Specifically, as shown in FIG. 6, when searching for a graphic updated before or after a designated time in the graphic of the facility drawing displayed on the display 18, the keyboard 20 is used. Data relating to a time range is input as time information corresponding to the update of the figure (step S101). For example, when investigating whether there is a graphic updated before October 31, 1997, time information corresponding to this date is input as a time range.
When the data relating to the time range is input, the attribute search processing unit 50 and the attribute information time search processing unit 48 search the attribute file 30 for attribute data matching the input time range (step S102). Then, the searched attribute data is edited by the processing of the display / edit processing unit 40, and is displayed in a list as an attribute information list in the window 56 (step S103). At this time, the graphic corresponding to the time range is emphasized and displayed while being distinguished from other graphics by the processing of the corresponding graphic emphasis processing unit 46.
If there is no graphic corresponding to the time range, a past position symbol is displayed at a location corresponding to the position information in the attribute information (step S104). Thus, the processing in this routine ends.

According to this embodiment, even if graphic data on a drawing is updated by deletion, position data and time data among attribute data related to the graphic are stored in the attribute file 30 as attribute data. Even if the graphic data is updated by deletion, the relevant time data is input when the graphic is updated, and the attribute file 30 is searched according to the input time data to extract the attribute data matching the input time data. The data can be displayed on the screen of the display 18, and the history of updating of past graphic data can be managed with minimum data from the display result.

[0025]

As described above, according to the present invention,
Even if the graphic information is updated, attribute information that matches the input time information can be extracted and displayed simply by inputting the time information corresponding to the update of the graphic, and the history related to the past graphic can be saved even with a small amount of information. Can be managed.
