摘要
阐述了对基于射频识别(RFID)的室内定位技术的研究结果,基于该原理的研究成果,以无线局域网为媒介、以C#编程开发实现了基于信号能量指标(RSSI)测距的室内定位应用程序,并设计测试方案对其定位误差进行测试与分析。经测试,该程序定位误差在2.5m以内,长时间解算值方差在0.04以内,证明了该技术实现室内定位的可行性。
The paper will elaborate the results of the RFID-based indoor positioning technology research.Based on the principle of research,with wireless local area network(WLAN)as medium,use C# programming to realize an indoor positioning application based on received signal strength indicator(RSSI)ranging.The positioning error of the program is tested and analyzed.According to the test report,the positioning error of the application is less than 2.5m,and the variance of long time compute is less than 0.04,which proves the feasibility of the technology to realize the indoor positioning.
