Abstract

PURPOSE:To facilitate the confirmation of attributes and figures by merging facility drawing data and attribute data and emphasizing and displaying the merged facility drawings or attributes. CONSTITUTION:For example, when a water feed device attribute and a character pattern are automatically merged, 'automatic merging' is selected in an icon area 102 and an automatic merging and correcting process part 112 performs the merging process. The automatic merging and correcting process part 112 starts an attribute retrieval part 114, which retrieves only water plug No. data on a certain house in an attribute file according to the drawing No. of the drawing which is currently displayed. A drawing retrieval part 113, on the other hand, retrieves the same No. as the water No. of each case, retrieved in the attribute file, on a main memory. When the same No. is found, the automatic merging and correcting process part 112 registers the drawing No. figure No., and attribute No. in a grouping file 107 and informs an emphasizing process part 116 of the figure No. to make an emphasized display. Consequently, the attribute or figure can easily be confirmed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a drawing management device for converting facility drawings such as water and gas piping systems, electricity and telephone wiring systems into digital information and managing the drawings.

[Conventional technology]

Conventionally, the status of facilities such as water, gas, electricity, and telephone piping and wiring systems has been managed using drawings drawn on paper or polyester film. At this time, if changes occur to the facility, the drawings will need to be revised. All drawing correction work must be done manually, which is problematic in that it requires a lot of effort and time, and the rate of errors is high. To solve this problem, for example, as described in Japanese Patent Application Laid-Open No. 63-254565, in order to manage facility drawings by converting them into digital information, a large number of facility drawings (topographic maps) stored in a file device are used. ,
System diagrams, symbol diagrams, etc.) are displayed on a monitor on a display device. In addition, drawing correction work is also performed using a display device.

[Problem to be solved by the invention]

Conventionally, when the resident name, faucet Na, water pipe diameter, etc. were changed, facility drawings and attribute information were changed manually. There is a problem in that changes may be omitted in a huge amount of drawing data, causing a mismatch between the data in the facility drawing and the attributes.

The present invention has been made in response to the above points, and its purpose is to combine graphic data and attributes using a function that automatically combines data on facility drawings and attribute information, and to share attribute information. To provide a drawing management device that can automatically change drawing data in accordance with the change of information.

[Means to solve the problem]

According to the present invention, if there is a mismatch between the data in the combined drawing whose attributes have been changed and the attributes in a drawing in which figure attributes have been automatically combined, the mismatch is corrected and the corrected part is highlighted.

[Effect]

Automatic merging of facility drawings and attribute information can be done automatically by assigning an item with that number to a unique number and attribute information already stored in the drawing, such as a water faucet. A list of attributes of the selected figures is memorized. Characters such as faucet name, name, management, pipe diameter, year of installation, etc. in the drawing are also imported from the drawing data into the attributes. At this time, these characters are also combined with attributes and drawing data accordingly.

Discrepancies between attribute information are eliminated. Furthermore, when attributes are changed, automatic verification is performed, characters in the connected figures are corrected, and this is highlighted on the screen for visual confirmation.
