摘　　要：从分析信号强度作为场景特征统计的数据所表现数据特征入手,进行Zigbee信号测距的可行性分析。结合系统要求选择指纹法定位方案,优化了测距方程。提出一种参考节点组网布局方案,确定最优参考点间距,大大消除了环境因数的影响提高位置指纹的匹配效率和准确度,进而大幅提高定位精度。Starting with analysising characteristics of statistical data, which takes the signal intensity as performance characteristics, we analysis the feasibility of Zigbee ranging signals. The ranging equation was optimized combining with the fingerprinting positioning scheme which is required by system. In this paper, a reference node network layout scheme was proposed, the optimal reference point spacing was determined, which eliminated the infl uence of environmental factor to improve the matching effi ciency and accuracy of fi ngerprint position, and the positioning accuracy was greatly improved.
