摘要

提出了基于RSSI的定位算法,并CC2431芯片做类节点构成一个Zigbee定位网络。根据节点接收信号强度的大小,估计出盲节点与参考节点的距离,选择3个接收信号强度最强的参考节点,利用三角定位方法确定节点间的位置,通过上位机z—Locion的实验测试,得到了较为理想的测试效果。
        This article puts forward the RSSI-based location algorithms,and makes the CC2431 chip as the class node to constitute a Zigbee positioning network.It estimates the distance between the blind node and the reference node according to the signal strength of the node receiving.Three of the reference nodes that with the strongest receiving signal strength is selected to determine the position between nodes with the method of triangulation positioning.Through the experimental test with position machine z-Locion the ideal test effect is achieved.
