Abstract

In Korea, the dependence on imported energy is very high, and research to reduce standby power is being conducted based on Zigbee, a low-power technology, to reduce wasted power and improve power efficiency. However, because Zigbee is not an IoT standard protocol and is not network-based, it is necessary to build a network with a separate gateway, and research on standby power is insufficient because the standards for international power consumption of devices are ambiguous. Therefore, in this paper, we applied the IoT standard protocol MQTT to the existing Zigbee technology to build a network network without a separate gateway, and designed and implemented a standby power reduction system that collects standby power degradation and user patterns. As a result of evaluating with the existing system, it was confirmed that about 7.11% of standby power was consumed compared to the existing system.

국내의 경우 수입 에너지에 대한 의존도가 매우 높아 낭비되는 전력을 저하시키고 전력 효율성을 향상시키기 위해 저전력 기술인 Zigbee를 기반으로 대기전력 저감 연구가 이루어지고 있다. 그러나 Zigbee는 IoT 표준 프로토콜이 아니고, 네트워크 기반이 아니기 때문에 별도의 게이트웨이를 두어 네트워크를 구축해야 하며, 국제적으로 제시하고 있는 기기 전력 소비량에 대한 기준도 모호하기 때문에 대기전력에 대한 연구는 미흡한 상태이다. 따라서 본 논문에서는 기존 Zigbee 기술에 IoT 표준 프로토콜인 MQTT를 적용하여 별도의 게이트웨이 없이 네트워크망을 구축하고, 대기전력 저하 및 사용자의 패턴을 수집하는 대기전력 저감 시스템을 설계 및 구현하였다. 기존 시스템과 평가한 결과 기존 시스템 대비 약 7.11%의 대기전력이 소모된 것을 확인하였다.
