The Oil Field Remote Monitoring System Based On GPRS/GIS/GPS

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.
