But transfers the oil to put the water station is the oil field production important link , how appropriately chooses , the design safely reliable , the data display accurate , the ease of operation nimble , is advantageous for the maintenance computer observation and control system , guaranteed the oil field measuring appliance , the microcomputer systematic security , is accurate , the steady movement , the optimized control , the realization safety in production and the energy conservation falls consumes , saves the manpower , the physical resource , enhances the working efficiency , and the production management level , is we at present in an oil field production important topic 而转油放水过程是油田生产的重要环节,如何恰当选择设计安全可靠、数据显示准确、操作方便灵活、便于维护的计算机测控系统,保证仪表、微机系统安全、准确、平稳运行,优化控制,实现安全生产和节能降耗,节省人力、物力,提高工作效率及生产管理水平,是我们目前油田生产中的一个重要课题。本论文结合油田转油放水生产过程的实际情况,以及计算机、 plc技术在油田的应用、发展现状,研究了微机测量控制系统的设计方案、检测仪表的选型、信号的传输处理、计算机软件的设计、硬件选择及实现。
The innovations of the paper are obtaining real - time and oriented field information rapidly by integrating gps receiver and conventional measure instrument ; processing and storing sample data , and expressing field information in grid graph understandability without a gis platform ; under guiding of dgps , picking up attribute information from graph 取得的研究成果有： gps接收机与常规检测仪表结合，实现快速实时地定位获取农田信息；脱离gis平台实现采样数据的存储和处理，并以栅格图形表达农田信息；在dgps引导下可以从属性信息分布图上提取属性信息。
But the output signals of the scene measurement instrument do not accord with the fieldbus agreement , if change or add the transform interface will cause the cost increase widely . the existing base - station type measures instrument does not still possess the function of control , and not accord with the fieldbus communication protocol 但现场使用的测量仪表输出信号不符合现场总线协议，若进行更换或配置转换接口而导致成本大幅增加；现有基站式巡回检测仪表尚不具备控制功能且不符合现场总线通信协议。
After analyzing the present situations of flowmeters , applications of single - chip computers in flow measurement meters , and the development trends of flowmeters , we ' ve designed an advanced intelligence vortex flowmeter , which can display the results on - the - spot ( includes instantaneous flow , total flow , temperature , pressure , and surplus capacity of the cell ) , communicate with the upper computers through the serial port and realize automatic copying meters 本论文通过对现有流量计及单片机在流量检测仪表中的应用现状的分析，结合流量计的发展趋势，设计了一种先进的智能涡街流量计，它能现场显示测试结果(包括瞬时流量、累计流量、温度、压力、电池剩余容量) ，并且通过串口可与上位机通讯，实现自动抄表功能。
In view of requires of precision agriculture and specialties of farmers , it tentatively use visual c + + to devise a software without gis platform . the software is developed to process the fused data and use grid graph to express field information . in the software , users can transmit the fused data to computer via serial communication between gps receiver and computer , and users can choose longitude latitude and attribute information from the fused data , and store these data in a data file 在本论文中，通过对国内外获取、表达基础农田信息的研究现状的分析，基于gps接收机获取的定位信息与常规检测仪表信息的融合，提出了gps接收机与常规检测仪表结合，快速实时地获取农田空间位置信息和属性信息的方法；针对精细农业实践的需要和农村用户的特点，试验研究脱离gis平台以图形的形式表达农田信息，应用visualc + +编程语言从底层开发具有gis功能的应用软件。
