【摘要】 网络和通讯技术的迅速发展,有力地推动了油田自动化管理水平的提高。采用无线监控系统实现对油井的数据采集和运行状态监控已成为一种必然趋势。本文提出和设计了一种基于GPRS 通讯方式的抽油机远程监控系统设计方案,旨在实现对油井的数据采集传输,完成示功图绘制,并可以实时监控抽油机的运行状态。GPRS 是一项新兴的数据传送业务,它利用现有的GSM 基站系统,通过和Internet 的连接就可以实现数据的远距离传输, 运行稳定可靠,漏码误码极少,而且不需组建自己的网络,大大节省了组网成本。实践证明GPRS 技术非常适用于要求实时性的、大数据量传送的应用场合。本系统主要包含三部分:抽油机控制单元、数据远程传输单元和监控中心数据处理单元。抽油机控制单元以Atmel89C52 单片机为核心,可以完成电压、电流、载荷和位移等数据的采集,实现数据的发送、接收处理以及对抽油机的控制;数据远程传输单元采用GPRS 通讯模块实现数据的传送,以完成下位机到监控中心的数据通讯工作;监控中心数据处理单元是用Borland 公司的C++Builde6.0 开发的,通过它可以实现对抽油机数据的存储、工作状态的显示、示功图的绘制和远程故障诊断分析等功能。更多还原

【Abstract】 The rapid development of network and communication technology, greatlypromotes the level of automatic management in oil districts. Adopting wirelessmonitoring systems to collect oil well data and monitor the working state hasbecome into an inevitable trend. The paper puts forward and design a scheme ofremote monitoring system for oil wells based on GPRS, which can collect andtransmit data of oil wells, draw instruction power diagrams, and monitor theoil-extractors all the time.GPRS is a new data-transmitting service, which can transmit data for a longdistance by using the present GSM base system and being connected to the Internet.It runs steadly with rare code missing or wrong codes. What is more, it needs not tobeuild our own network, so the cost of building network can be saved. Practiceshows that the GPRS technology is very fit for those applications in which a greatdeal of data needs transmitting instantly.The system mainly includes three parts: oil-extractors control unit, remote datatransmission unit and data processing unit in the monitoring center. Theoil-extractors control unit is on the base of Atmel89C52 MCU, which can collectdata, such as voltage, electric current, loads and displacement. It also can send andreceive data, and control oil-extractors. The remote data transmission unit transmitsdata by GPRS modem so as to implement the communication between theoil-extractors and the monitoring center. The data processing unit in the monitoringcenter which is developed by C++ Builde6.0 can store oil-extractors display theworking state, draw instruction power diagrams, and diagnose the malfunctions ofoil-extractors.更多还原
