一种基于高频RFID的室内定位方法的设计与实现
Design and Implementation of an Indoor Location Method Based on UHF-RFID
摘要
Abstract
An UHF-RFID directional reader is drived by a step motor to whirl with a constant angular, which depends on the lobe pattern for it's directional characteristic. And all tags in the area covered by the reader are scanned to obtaining the TDOA between found-time and loss-time, thus, AOA can be caculated to make the linear formulation between the tags and reader in axis. The coordiante of every tag can be estimated by using the trajectory of every tag in accordance with it's circle formulation and the radian that the reader has been whirled. In the location system, only two directional readers are in work with some tags, which reduces the complexity and enhances it's accuration and efficiency.关键词
