Abstract

The recognition rate of RFID system is made a big difference by the selection of tag type and performance of reader, packing materials and the attachment location of tag and the recognition of angle according to the above factors. Water content is the most effective factor among the various elements that affected to the recognition of RFID as the center. Therefore, the purpose of this study was to measure the RFID recognition rate per water content, the distance recognition rate of RFID tag, the RFID tag and the recognition rate by contact area. In analysis of recognition rate according to water content, 100% of recognition was possible when food product contained 0~25% moisture. However, when water content was over than 30%, recognition rate was declined less than 95%. The recognition rate between RFID tag according to water content was higher when distance was over than 0.3 cm. In the recognition rate about the contact area of RFID tag according to water content, the recognition rate was declined when the contact area becomes wider.

RFID 시스템의 성능은 태그의 종류 및 리더 자체 성능뿐만 아니라 RFID 시스템을 응용하기 위한 물품의 종류, 포장 재질에 따른 태그 선택과 이에 따른 태그의 부착 위치 그리고 Antenna의 인식각도 등에 따라 큰 차이를 보인다. 본 연구는 이를 위해 RFID 인식률에 영향을 미치는 다양한 요인 중 가장 큰 영향을 미치는 수분함량을 중심으로 수분 함량별 RFID 인식률과 수분 함량에 따른 RFID 태그 사이의 거리 인식률 그리고 수분 함량에 따른 RFID 태그와 접촉면적에 따른 인식률을 측정하였다. 수분함량에 따른 인식률 분석에서는 0~25%의 수분을 함유할 경우 100% 인식이 가능하였으며, 수분함량이 30% 이상부터는 95% 이하 수준으로 떨어졌다. 수분 함량에 따른 RFID 태그 사이의 거리 인식률은 태그가 맞닿아 있을 경우보다 0.3 cm 이상일 경우가 더 인식률이 높았으며, 수분 함량에 따른 RFID 태그와 접촉면적에 따른 인식률에서는 접촉면적이 넓어질수록 인식률이 떨어지는 것을 확인하였다.
