2 . based on the built spatial and attribute database and the basic plat of visual foxpro , by the technology of objected programming , designed and built the land resource dynamic monitor information system ( lrdmis ) for applied 以空间和属性数据库为基础,以visualfoxpro为基础平台,采用面向对象的编程方法,设计建立了小流域土地资源动态监测信息系统( lrdmis ) 。
The system is perfectly realized through the four counts below : 1 ^ using configuration soft compile the person - computer interface for information management of grain depot content and the application program for data collection . this program will finish real time data collection and conversion and will dynamic come after each bam flash - locks run state and will supervise and record the run instance ^ startup or stop time 2 ^ using visual foxpro workout report table for grain depot content information management system witch carry out database management function . 3 ^ using visual c + + workout communication program between force control configurable soft and aptitude instruments 本课题从下面四个方面实现系统要求: 1利用组态软件forcecontrol2 . 0编制了仓容信息管理系统的人机界面和数据采集应用程序,完成设备状态的实时采集和转换,动态跟踪各粮仓闸门的运行状态,监视并记录斗提机的运行情况、启动和停止的时间; 2利用visualfoxpro编制了仓容信息管理系统报表记录应用程序,实现数据库的管理功能; 3利用visualc + +编制forcecontrol组态软件与智能仪表以(在线流量计)为例的通讯程序,实现下列两项功能: ( 1 )接收来自在线流量计的数据。
It hopes to come to a sententious conclusion by optimizing location and capacity of reactive compensation . the main contributions of the thesis as follow : 1 ) it introduces the three current ways and corrects the habitual errors in engineering at present . it sums up experience and puts forwards to disposing fundamentals . the software is programmed for different objective function by visual foxpro and has been used in practice 主要解决以下问题并形成结果: 1 )从实用性出发,对工程中常见设计错误进行举例、修正;针对目前工程通用的三种补偿方法进行分析,总结工作经验,提出具体配置原则;并对补偿的不同目标(电压、功率因素)进行基于visualfoxpro的软件编程。
It takes powerbuilder for the development language and it utilizes the ole / odbc technology and " 3s " technology for the system integration . on the same time , it adopts the c / s and b / s unite mode to fulfill the analyze and application of urban and suburb forestry resource ' s attribute data and graphics data 本文以mapinfo软件和visualfoxpro为平台,以powerbuilder为开发语言,并利用ole / odbc技术和“ 3s ”技术进行系统集成,同时采用c / s与b / s结合的方式完成城域森林资源属性数据和图形数据的分析与应用。
On the basis of study of theory and method on land use status information system construction , by material collection , graph scanning , data gather , graph edition , data processing , database establishment , system improvement , system probation and so on , we established property database based on visual foxpro , and established land use status information system ultimately 在土地利用现状信息系统建设理论方法研究的基础上,通过资料预处理、图纸扫描、数据的采集、图形编辑、数据处理及系统数据库建立、系统完善、系统试用等工作,按检查、编辑修改、检查、再编辑修改、再检查的方法循环进行,并用visualfoxpro建立属性数据库,最终建立土地利用现状信息系统。
