【摘要】 电力作为国家的支柱能源和经济命脉,其安全稳定运行不仅关系到国家的经济发展,而且维系着国家安全。然而电力设备,尤其是电力线路却常年累月暴露于野外,很容易出现故障。电力线路巡检则是有效保证电力系统安全的一项基础工作。现有的一些电力线路巡检方法由于管理上和技术上的缺陷而不能够及时准确地反映电力设备的运行状况,这对保证电力系统的稳定运行非常不利。所以研究和开发先进的电力线路在线巡检管理系统,及时发现问题,这将有利于提高电力系统运行的安全可靠性。本文通过应用现代信息技术、融合GPRS无线通信技术、GIS技术、GPS技术、Internet网络数据共享技术,对电力线路巡检系统进行了研究和总体设计。实现了巡检数据的无线实时传输,达到了巡检计划与突发状况同步更新的目的。本文首先对巡检系统开发所用到的现代信息技术进行了探讨。首先研究了数据传输方式GPRS的基本特点、相关技术以及发展前景。比较研究了C/S和B/S两种流行软件结构模型,为下一步系统的开发做了一个很好的准备。其次,采用基于.NET框架的三层B/S体系结构进行总体设计。提出GPRS与Internet无线组网的系统总体构架,解决现有电力线路巡检系统的实时性瓶颈。在此基础上对系统的GPRS数据传输流程及软件总体结构和功能做了详细设计。然后,对GPS/GIS技术的应用做了研究。同时对系统数据库也进行了设计,为计算机辅助决策系统对大量的数据进行分析、挖掘提供数据支持。更多还原

【Abstract】 Electric power as the country’s most important energy sources and economic, operated in security and stability, not only connect with the country’s economic development, but also maintain national security. However, the power equipments, in particular the power lines are exposed to the wild perennially, it is easy to have failure. Electric Power Line Inspection is a basic work for effectively guaranteeing the safety of an electric power system. Some of the original power lines can not reflect the state of the electrical equipments’ running duly and accurately because of the limitation in management and technically, it is very disadvantage for guaranteeing the power system running steadily. Therefore, research and development of advanced intelligent inspection management system, promptly identify problems, which will help improve the power system operating in security and reliability.In this paper, through the applications of modern information technology, integration of GPRS wireless communication technology, GIS technology, GPS technology , Internet data sharing technology, electricity polling system has been researched and design. That carries out the wireless real-time transmission of inspection data; achieves the purpose of sync update between a state of emergency and Inspection plans. Simultaneity, helping managers who make the inspect plan make more decision-making, the first step to achieving the intelligence of the inspection work.In this paper, firstly, the modern information technology used in the inspection system developed is discussed. The basic characteristics, related technology and the development prospects of data transmission method GPRS are researched in details. Compare with the two popular software configurations’ model of C / S and B / S, we do a very good preparation for the next step development of systems. Secondly, takes the B/S three-tier architecture system which based on the .NET framework to make the system architecture design. We propose the overall framework of GPRS and Internet wireless network, and solve the real-time bottlenecks of the existing power lines inspection system. On this basis, the GPRS data transmission processes and the software overall structure and functions have been done the detailed design. Then the application of GIS/GPS technology have been introduced. At the same time, the database is also designed, and that it also provides support for computer-aided decision-making system to the large amounts of data analysis and data mining.更多还原
