基于信息融合的电网作业智能终端定位算法

现有的用于电网作业的智能终端设备在定位时采用GPS和无线基站定位.GPS定位和无线基站定位因在部分区域存在信号弱或者无信号的情况，导致定位误差大，定位漂移.本文提出了AGPS、无线基站定位和行人航位推测相结合的基于粒子滤波的信息融合定位算法，并分析了算法实现原理.实验表明，在GPS信号较弱或者无信号的条件下，智能终端依然可完成高精度定位.

Information Fusion-Based Positioning Algolrithm for Power Grid Operation Terminal Equipment

GPS and wireless base staion positioning system integrated in terminal equipment has the disadvantages of obvious positioning errors and drifts under the condition of weak or no signals in some areas. This paper presents the hybrid location algolrithm based on particle filter combining AGPS, wireless base staion location, and Pedestrian Dead Reckoning (PDR). The principle of the hybrid location algolrithm is carefully described. Experimental results show that the terminal equipment can be accurately positioned even under the condition of weak or no signals of GPS.
