| 摘 要： | 作为一种全新的定位技术,RSSI(Receive Signal Strength Indicator)被广泛应用在WLAN(Wireless Local AreaNetwork)中的室内移动机器人定位领域。为采用几何法进行室内移动机器人定位,提出基于RSSI的测距方法。分析无线信号传播的特点和RSSI测距的原理,建立无线信号传播损耗模型。采用带有无线网卡的笔记本和LINKSYS路由器构建测距实验系统,其中路由器作为基站固定于一点,无线网卡作为移动节点时刻发送信号,通过实验得到距离d与RSSI值的关系曲线,利用无线信号传播损耗模型中的参考点信号强度和比例因子进行标定,并分析测距精度。结果表明,影响测距精度的因素主要包括障碍物和空间大小等。根据确定的无线信号传播损耗模型进行测距实验,实验结果表明:在3 m范围内测距最大误差为0.79 m,能够较好地满足室内移动机器人定位的需要。 |
