DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drawing management system for digitally managing and managing facility drawings such as water and gas piping systems, electricity and telephone wiring systems.

[0002]

2. Description of the Related Art Conventionally, facility drawing information such as piping such as water supply, gas, electricity, and telephone, wiring system, etc. has a hierarchical structure for each use, and each facility information and map information is vector information. That is, it is represented by graphic information. Graphic information includes line graphic information that stores the coordinates of constituent points, character graphic information that stores character codes and display coordinate positions and inclinations, and symbol graphic information that stores symbol codes and display coordinate positions and inclinations. being classified. These drawing information are displayed on the display in any combination of hierarchies according to the purpose. On the other hand, since all the information related to the facility cannot be expressed only by the drawing information, it is described in the attribute information related to the facility corresponding to the corresponding facility graphic on the facility drawing. The drawing information and the attribute information can be mutually searched from each other as described in JP-A-63-254565.

[0003]

By using the above-mentioned prior art, a user can specify in a drawing an event that changes over time in an area such as a construction range or an accident range, or temporarily specify a specific position range on the drawing. If the user wants to re-display the position range again later, the user must remember the drawing position. However, in the above-described method, when the user forgets the drawing position range, it is difficult to reproduce the position range from the vast facility drawing range.

[0004] It is an object of the present invention to provide a drawing management apparatus capable of storing a display drawing position together with a display scale at the time of a user's instruction or automatically storing the display drawing position at a specific time interval so that the position range can be easily reproduced. Is to do. Another object of the present invention is to provide a drawing management apparatus which enables a user to add an arbitrary comment to the drawing management apparatus so that a position can be reproduced from the contents of the comment.

[0005]

The above object can be achieved by providing means for retrieving and displaying a position history, and means for allocating a position on a display drawing as a history according to a user's instruction.

Means for searching and displaying the position history is as follows:
Position search means for searching for a plurality of continuous position histories or one position history specified by a user of position history information storing an accident occurrence position, a construction position, and the like in the file device; and It is constituted by drawing display processing means for displaying drawing information on the display device based on the position coordinates and the scale from the position history.

The means for allocating a position on a display drawing as a history in accordance with a user's instruction is to store the coordinates of the center position of the drawing being displayed on the display device, the display scale, and the current date in the file device at specified time intervals or at the time of user designation. It is constituted by position history storage means for storing as position history information. A comment input by a user can be added to the position history information.

The facility drawing information having a hierarchical structure is digitized as vector information represented by X and Y coordinate values, that is, graphic information. The X and Y coordinate values have a relative relationship with the latitude and longitude, and are expressed to the user as latitude and longitude information. Further, the facility drawing displayed on the display device can be changed to an arbitrary scale or moved in an arbitrary direction of the display position according to a user's specification. For this reason, it is possible to easily display a range extending over an arbitrary range such as a construction range or an accident range on the screen. By storing the screen display range automatically at the latitude and longitude of the center of the screen, or the internal X and Y coordinate values, and the display scale, or by the instruction of the user, the position range such as the construction range and the accident range can be easily stored. It becomes possible. Further, it is possible to input an annotation such as user information such as "water cut accident near the XX road" and add this to the position history information.
