摘　　要：本文以电力网的安全运营和线路巡检的高效、可靠性为主旨,研发基于GPS定位导航的电力巡检PDA系统。该系统以嵌入式GIS技术为核心,结合GPRS无线通信技术和数据库技术,结合Saga-Husa自适应滤波与强跟踪kalman滤波算法并以收敛性判断为依据,构建了改进的自适应滤波算法来提高PDA上的GPS定位精度,实现巡检过程的精确定位和数据采集,并智能导航野外巡检路径,通过GPRS和USB端口实现与服务器端的数据交互,确保巡检管理层人员实时掌握并监督管理野外巡检任务的执行情况。Aiming at the safety operation, the high efficiency and reliability of line inspection of power grid, this paperinvented a power line inspection PDA system based on GPS positioning and navigation. The system used embedded GIStechnology as the core combing with GPRS wireless communication and database technology. The Saga-Husa adaptive filterand strong tracking Kalman filtering algorithm were also adopted to construct a modified adaptive filtering algorithm forimproving the accuracy of the GPS positioning accuracy on PDA with the convergence guaranteed. The precise positioning,data collection of the inspection process, and the intelligent inspection path navigating were achieved. Data interaction withthe server was implemented by GPRS and USB port to ensure inspection management staff to control and supervise thedynamic status of field inspection tasks in a real time manner.
