摘要/Abstract

摘要： 无线射频识别(radio frequency identification, RFID)技术应用于室内定位时, 易受周围环境影响, 出现电子标签信号强度弱、无法读取、定位精度降低甚至无法进行定位计算等情况. 提出使用RFID/航位推算(dead reckoning, DR)组合定位系统对室内运动物体进行定位. 利用RFID 系统校正DR 系统的累积误差, 并在RFID 信号丢失时, 利用DR 系统辅助RFID系统进行有效定位. 实验结果证明, RFID/DR 组合定位技术能有效提高室内运动物体定位效果和精度.

关键词: 航位推算, 室内定位, 组合定位, 无线射频识别技术

Abstract: Radio frequency identification (RFID) is influenced by the environment, when the RFID is used as an indoor location way. The signal intensity of e-tag becomes weak and can’t be read, which will decrease the location precision, and even cause the location system fail. An integrated location system based on RFID and dead reckoning (DR) is proposed to apply on indoor location of dynamic object. The RFID can eliminate the accumulative error with time. The DR system can assist the RFID system, when the e-tag signal lost. Based on the experiment, the integrated location system can improve the effect and precision of indoor location.

Key words: dead reckoning (DR), indoor location, integrated location system, radio frequency identification (RFID)
