摘　　要：随着信息技术的发展,人们对复杂的室内环境下的定位与导航的需求日益增大。文中实现了一种基于LQI的低成本、实用的无线传感器定位系统,系统包括硬件平台、节点通信程序和上位机监测软件三部分。硬件平台以集成了射频与ARM7微控制器的MC1322X芯片为核心,包括射频模块、辅助电路、功能指示电路等。节点软件的开发以FreeScale公司提供的BeeStack协议栈为基础,文中同时给出了节点的软件实现方案。With the development of information technology, people＇s demand for positioning and navigation in complex indoor environment is increasing. A wireless indoor location system based on link quality indicator （LQI） is designed and implemented. The location system included three parts： hardware platform, communication program of nodes and PC monitor software. Based on MC1322X, the hardware platform includes RF module, auxiliary module and function indication circuits.The exploitation of node communication program is based on BeeStack protocol stack which is provided by FreeScale, and elaborate software solution is oroDosed in this oar^er.
