针对我国农村供水工程图纸资料缺乏及推广不便的现状,利用数据库开发软件Microsoft Access可以导入OLE数据对象的优点,分析设置多种字段描述农村供水工程图纸建立数据表,将图纸文件作为OLE对象导入数据表,根据实际对图集的应用需求建立各种查询,进而构建人机交互界面并完善图纸数据库。该图集数据库现有取水、调节、输配水、水质处理与净化、水厂总体设计、电气与自动控制图纸,并且可以将增加的农村供水工程图纸文件导入到图集数据库中。实际应用结果表明,该数据库能够满足大量农村供水工程图纸存储和分类的要求,将图纸数据库与互联网结合使用,用户能够在线查询、下载和打印图纸。
In view of the lack of drawing materials and the inconvenient status of rural water supply project in our country, the advantages of importing OLE data objects with database development software Microsoft Access are analyzed. By setting a variety of fields to describe the data sheets of rural water supply engineering drawings, importing the drawing files as OLE objects Table, according to the actual application of the Atlas to establish a variety of inquiries, and then build human-computer interface and improve the drawing database. The Atlas database currently has access to water, regulation, transmission and distribution water, water treatment and purification, waterworks master design, electrical and automatic control drawings, and additional rural water supply project drawing documents can be imported into the atlas database. The practical application shows that the database can meet the storage and classification requirements of a large number of rural water supply engineering drawings. The database of drawings and the Internet can be used in combination with the Internet to enable users to inquire, download and print drawings online.
