Abstract

A smart tag complements various problems caused by the expansion of the use of existing magnet cards. This emerged as a result of the need for alternative means to perform safer and more diverse functions. RFID tags are becoming increasingly ubiquitous sensor networks and Internet of Things technologies as they give everything an ID, enabling automatic recognition of objects and forming a communication network between them. In this paper, a contactless RFID smart tag reader composed of RFID tags and readers using AVR processor was developed. The system has a low frequency band of 13.56MHz and is designed by PWM method of communication velocity 26.48kbps. The developed RFID smart tag board showed a faster response rate than the typical RFID system as a result of the simulation, and the actual experiment also showed an improvement in response rate.

스마트 태그는 기존에 사용하고 있던 마그네트 카드의 사용이 확대되면서 나타난 여러 가지 문제점들을 보완하여 보다 안전하고 다양한 기능을 수행할 수 있는 대체 수단의 필요에 의하여 등장하였다. RFID 태그는 모든 사물에 ID를 부여하게 되어 사물의 자동인식이 가능해지며 이들 간의 상호 통신 네트워크가 형성됨으로써 유비쿼터스 센서 네트워크와 사물인터넷 기술로 발전해 가고 있다. 본 논문에서는 AVR 프로세서를 이용하여 RFID 태그와 리더로 구성되는 비접촉식 RFID 스마트 태그 리더를 개발하였다. 이 시스템은 13.56MHz의 저주파 대역을 가지며 통신 속도 26.48kbps의 PWM방식으로 디자인하였다. 개발된 RFID 스마트 태그 리더는 시뮬레이션 결과 일반적인 RFID 시스템보다 빠른 응답속도를 나타내었고, 실제 실험에서도 응답률의 개선이 나타났다.
