【摘要】 随着网络和通讯技术的迅速发展,远程监控系统在工业控制领域中有着越来越重要的意义。在许多工业场合,尤其是对于油田这样分散的、无人值守的现场,需要对井场数据进行实时采集,以便及时了解现场的情况,并根据现场情况对油井进行实时控制。传统的远程监控系统的实现方式一般需要建设并维护通信网络,投资和维护费用高。随着通信技术的发展,原有的远程监控系统已经不能满足多方面的要求,市场急需一种功能与现场生产结合紧密、性能稳定、建网成本低、通信可靠的远程监控系统。本文提出了一种基于GPRS(General Packet Radio Service)/GIS(Geogra-phic Information System)/GPS(Global Positioning System)的油田远程监控系统。结合目前油田所使用监控系统情况,系统在设计过程中采用了模块化设计思想,各功能模块可根据油田的不同需求单独使用。系统主要由GPRS/GPS无线通信系统、示功图采集装置和油田GIS智能分析诊断软件组成。在系统方案中通过对当前应用较为广泛的无线通信方式的性能对比,最终系统采用了以GPRS并结合无线自组网的无线通信方式。系统在设计中采用MODBUS协议,提高了系统的集成度和可扩展性。示功图是掌握油井整体运行工况的一个重要方法。针对目前油田使用的示功图采集装置安装测量不便、实时性差问题,开发了一体化无位移传感器远程示功图采集装置。本文详述了该装置的设计原理及现场应用状况。油田GIS智能分析软件负责远程采集装置数据的接收、汇总、分析和处理,是整个系统的重要组成部分;油田GIS智能分析软件采用Borland公司的C++ Builder 6.0作为开发平台,实现了数据的分析、处理、存储、工作状态分析、故障报警、油井状况的电子地图快速查看等功能。本系统在2007年已经投入使用,整体运行良好,实践证明本系统的实用性,先进行和可靠性。更多还原

【Abstract】 With the rapid development of networks and communication technology, the remote monitor control system is more and more important in the industry control field. In many industrial occasions, especially for some distributed and no watcher sites such as oil field, we need to collect the real time data to know the situation of the sites in time and to do real-time control. General traditional remote monitoring systems need to build and maintain a communication network, and this needs to spend much more on investment and maintenance. With the development of communication technique, the traditional remote monitoring system has been unable to meet various requirements, and the market needs a combination of function and the production remote monitoring system has integrated, stable performance, low cost of network construction and reliable communication.The oil field Remote Monitoring System based on GPRS(General Packet Radio Service)/GIS(Geographic Information System)/GPS(Global Positioning System)is put forward in the dissertation. Combining the current monitoring system used by the oil field managers now, the system took a modular design concept in the design process, and the functional modules can be used alone under different needs.The main compositions of system are the GPRS/GPS wireless communica-tion system, the dynamograph collection equipment and the intelligent analysis oilfield GIS software. Compared with the wireless communications which has the wider application, the system chooses a GPRS combined with wireless ad hoc network finally. The systems use the MODBUS protocol in the design to improve integration and scalability of the system. Dynamograph is an important method to master the conditions of the oil wells. According to the installed inconvenience, poor real-time of the dynamogra-ph collection equipment used presently, the system designs integrated dynamo-graph collection equipment without displacement sensor. The dissertation details the design of the device and the field application.Oil field GIS analysis software is an important part of the system which is responsible for intelligent remote data acquisition devices to receive, aggregate, analyze and process, and the software use Borland C++ Builder 6.0 as a develop-ment platform. This software has the functions of the data analysis, processing, storing, and working state analysis, fault alarm, the situation of oil wells electron-ic map show.This system has been put into use in 2007, and the overall well-functioning practice proved the practicality and the reliability of the system.更多还原
