VFP和CAD技术在生成流速流向图中的应用

Application of VFP and CAD in Production of Velocity Flowgraph

主要介绍了数据库编程语言VFP和CAD在生成流速流向图中的应用情况。在进行水文测验过程中各断面位置所在的垂线实测到的流速流向需要制作成图件,为了能够规模化、标准化成图,采用VFP编程对数据进行批量处理,并生成CAD图,进而可以对文字、线条进行随意设置以及多条垂线的图形合并比较。并可根据需要转换成PDF图形文件,作为成果报告的附件,满足工作和生产的需要。

Application of the database program language VFP and CAD in production of velocity flowgraph is described in the paper. During the hydrological test process,the measured velocity and flow direction by the plumb line where the section is seated shall be transformed into graph. To transform the graphs in scale and standard,VFP program is applied to handle the data in batch as well as form CAD. Furthermore,both characters and lines can be arranged freely and graphs with multiple plumb lines can be merged and compared. As required,it can be transferred into PDF format for the report attachment to satisfy work requirement.
