적외선 센서를 이용한 저 전력 RFID 시스템 설계 및 구현

다국어 초록 (Multilingual Abstract)

This paper proposes an efficient power control RFID system, which has control by separating both entire power of RFID system and power control device of RF communication. PCRS shut off power when not used, which can remove unnecessary power consumption of sleep mode and RF-communication module. When PCRS detects users around through infrared ray sensors, it allows power on and is on standby periodically going on-and-off to reduce the power consumption of RF-communication module. If user tag provides user information, it decreases power consumption by blocking the entire power supply when not used for a while and the user information process completed by MCU. Given the operating ratio 0.3, existing RFID system has 20.1㎃ at system operation current, 20.3㎂ at sleep mode current and 20.12㎃ at standby current. However, the same condition given, PCRS has 5.4㎃ at standby current. In conclusion, PCRS can decrease power consumption at standby current as many as 4 timescompared to existing PCRS system.
