摘要
针对ZigBee信号位置存在依赖性的问题,在菲涅尔区模型的基础上,结合小尺度活动位置依赖性问题的特点,提出了ZigBee信号在无线感知系统中位置依赖的形成机理。通过实验定量定性分析了手指的运动轨迹、位置和信号波形之间的关系,探索设备场景下的位置依赖性问题,并结合应用实例得出了解决方案。
Aiming at the problem of position dependence of ZigBee signal,based on the Fresnel zone model and the characteristics of small-scale activity position dependence,the formation mechanism of position dependence of ZigBee signal in wireless sensing system is proposed.Through experiments,the relationship between finger trajectory,position and signal waveform is quantitatively and qualitatively analyzed,the problem of position dependence in equipment scene is explored,and the solution is obtained combined with an application example.
