Abstract

As RFID systems are applied to various fields and applications such as supply chain management, asset management, location based applications etc. the requirements becomes diverse. For example, Much higher performance, TCP/IP protocol stack are required in some applications. However, low end processors based systems such as 8051 processor can not meet such requirements due to their low processing capacity and limited size of memory. In this paper a UHF band RFID system which meets the EPC Class-1 Generation-2 specification with ARM920T-based processor is implemented and tested.

RFID 기술이 다양한 분야에 적용됨에 따라 각 분야의 특성에 맞게 RFID 리더에 요구되는 기능들도 다양해지고 있다. 그러나 현재 구현된 8051 프로세서를 기반으로 한 시스템은 프로세서의 처리 용량의 한계 및 메모리 크기의 제한 등으로 인하여 다양한 요구 조건들을 충족시키기에 부족하다. 본 논문에서는 다양한 요구 조건들을 충족시키기 위해서 임베디드 시스템에서 많이 사용되고 있는 ARM920T 기반의 프로세서를 이용하여 EPC Class-1 Generation-2 규격을 만족하는 UHF 대역의 RFID 시스템을 설계하였다.
