摘　　要：单纯使用GPS系统无法解决复杂环境下的定位问题,利用各类无线与传感器技术实现室内定位系统成为近年来的研究热点。RFID技术具有成本低、寿命长、通信速率高、覆盖范围广、部署方便等优良特性,因而成为极具前景的室内定位手段。基于RFID技术,研制了以MSP430为主控芯片、兼容CC1101与CC2500两款射频模块的RFID标签与读卡器,采用LAND-MARC算法,实现了一套完整的室内定位系统。通过反复实验分析与参数配置改进,提高了系统的定位精度与稳定性,可应用于人员、资产管理系统等场景。It＇ s difficult to use only GPS to solve positioning problem under complex environments, using wireless and sensor technology to realize indoor localization has been a hot topic in recent years. RFID has become a promising indoor localization method due to its advantages of low cost, long lifecycle, high communication rate and ease of deployment. Based on RFID technique this article presents a complete indoor localization system which uses MSP430 as the microcontroller and is compatible for both CC1101 and CC2500 RF modules. This system uses LANDMARC as the localization algorithm. Through the repeated experiments and parameter reconfiguration, the result achieves a better accuracy and stability, and can be applied in people or asset management system.
