| 摘 要： | 基于接收信号强度的无线网络室内定位是定位领域的一个新的研究热点。为了满足室内定位对精度的要求,常见的方法是利用通信模块在室内环境下建立定位网络。介绍了基于Zig Bee协议的CC2431定位系统,分析了基于滤波算法和三边测量的定位算法,在支持Zig Bee协议的CC2431模块上实现了定位算法,通过在室内环境下进行实测实验对比了2种定位算法的定位误差,结果表明:提出的定位算法较系统自带定位算法提高了定位精度,定位效果良好。

| Abstract: | RSSI-based indoor location in WLAN is a hot research topic in the field of location estimation.To meet the require of indoor location,more and more methods directly use off-the-shelf wireless communications module to estimate the location of the target node.CC2431 location system based on Zig Bee protocol,location algorithm based on smoothing algorithm and trilateration and application of RSSI-based location technology are introduced.Results show that the localization system is used in real indoor environme... |
