| 摘 要： | 为采用几何法进行室内移动机器人定位,提出了基于有源射频识别(RFID)信号强度测距方法.分析了无线信号传播的特点和无线信号强度指示(RSSI)测距的原理,建立对数-常态分布传播损耗模型.采用有源RFID的HR-6020C读写器和WS-HT06电子标签构建实验系统,其中读写器作为基站固定于一点,电子标签作为移动节点时刻发送信号.通过实验得到距离与RSSI值关系曲线,利用有源RFID系统对理论模型中的参考点信号强度和比例因子进行标定,并分析了测距精度.影响测距精度的因素主要包括标签的位置、数量和实验环境等.根据确定的传播损耗理论模型进行了测距实验.结果表明,在3 m范围内测距最大偏差为41.68 cm.这为基于RFID的室内场馆移动机器人定位提供了依据,可以满足机器人的定位精度要求.
