Low-Frequency Localization And Identification System With Zigbee Network

Abstract

Abstract-Location awareness is important in health care. One way of generating this is a lowfrequency radio frequency identification (RFID) location system that has been developed. The system tracks RFID tags with a quad antenna matrix that is placed under the floor surface. The tag can be also used to receive alarms and send acknowledgements via a ZigBee network. This article discusses the requirements of this kind of a tag, its structure, and its location accuracy. The demonstrated RFID system can locate people and items inside the building with an accuracy of 1.1 ± 0.5 m (S. D.).

A novel concept of a wearable information appliance using context-based human–computer interaction

“…The system comprised three units: A NFI system was used to locate a person and excite the RFID tag; the existing RFID tag [39] was used for location and identification source; and an iPod Touch multimedia player (Apple Inc., California, USA) was used as the multifunctional name label. iPod Touch multimedia player is approximately the same size as a normal name tag, it has a 3.5-inch capacitive touch screen and WLAN (Wireless Local Area Network) radio to communicate with the NFI system [35].…”

“…Since previous work has shown the advantages of ZigBee over, for example, WLAN [39], all the context-based information can be sent through the ZigBee network. With a Pocket WinView handheld device, it is possible to display vital patient parameters using either WLAN or GPRS (General Packet Radio Service) networks [40].…”

“…With the RFID system, people can be both located and identified [10]. However, the RFID tracking is not as accurate as the NFI localization [39].…”

An indoor positioning algorithm and its experiment research based on RFID

“…With the deepening of research on Internet of things technology, researchers are not only concerned about the reliability of data transmission [17] and the algorithm design [18,19], but also the development of positioning device [20,21] and its application such as the vehicle license plate [22,23], the wrist watch [24] and so on. Not only that, some of the techniques have also been integrated into the indoor position system, such as the Inertial Navigation System [25] (INS), the Finger Printing Method [26] (FPM), and LF RFID localization system [27].…”

A Pc-Based Wireless And Remote Control For Shape Judgment Equipment Using A Zigbee Module

“…Wang et al [11] presented an intelligent fuzzy controller for air-conditioning with Zigbee sensors. Ropponen et al [12] also developed a low-frequency localization and identification system with a ZigBee network. Moreover, Wang et al [13] developed a visual navigation and remote monitoring system for an agricultural robot using a wireless local area network (LAN), a slave computer, and a host computer.…”
