Intelligent Grounding Wire Positioning System Based on GPS Dual Positioning

复杂电网结构的智慧接地线定位过程会受到其他线路的干扰,导致定位结果差,设计一种基于GPS双定位的智慧接地线抗干扰定位系统。对单片机处理器内部组成进行优化,在其中嵌入GPS定位模块和GSM定位模块,并分析了双定位模块的有关参数。计算不同信号所对应的载波相位与时间差,根据GPS/GSM双定位系统的信息接收模式进行数据信息融合,优化定位流程。系统性能测试结果表明,与传统定位系统相比,定位误差更小,定位精度更高,具有一定优越性。

The intelligent grounding wire positioning process of complex power grid structure is disturbed by other lines,resulting in poor positioning results.An anti-interference positioning system of intelligent grounding wire based on GPS dual positioning is designed.It optimizes the internal composition of single chip processor,embeds GPS positioning module and GSM positioning module,and analyzes the relevant parameters of dual positioning module.It calculates the carrier phase and time difference corresponding to different signals,fuse data and information according to the information receiving mode of GPS/GSM dual positioning system,and optimizes the positioning process.The system performance test results show that compared with the traditional positioning system,the positioning error is smaller and the positioning accuracy is higher,which has certain advantages.
