一种功率可调的RFID室内动态定位方法
A Power-Adj ustable Method for RFID-based Dynamic Positioning
摘要
Abstract
Most of the indoor positioning algorithms based on RFID require the reader to record some measured parameters such as RSSI and TOA,which results in a high cost of the entire system.The RFID-based dynamic positioning scheme is an innovative method to locate a target tag by a system with a moving RFID reader and some reference tags without recording any measured parameters.Although the positioning accuracy can be tens of centimeters,the location path is blind,which results in a poor positioning efficiency.To solve this problem, this paper proposes a power-adj ustable method for dynamic positioning.Moreover,a MATLAB GUI is designed for monitoring the status of all the tags read by the moving reader whenever necessary.Results of experiments indicate that the proposed power-adj ustable method could save considerable time for positioning and improve the efficiency of the system compared with the original dynamic positioning scheme.Besides,the positioning accuracy for the target tag on the border of the area could increase by nearly 20%.关键词
