Abstract

In this paper, we have developed a device to reduce the standby power consumption that is unnecessarily consumed in unused electrical appliances. The Doppler sensor is used to automatically power off and power off the outlet depending on whether or not a person is present near the outlet. The Doppler sensor uses a coaxial cable trap to design a transmitting antenna and emits a 10 GHz band RF signal and receives a reflected wave signal whose wavelength is reflected from the target object to the receiver to detect an object and recognize human approach. It automatically cuts off and restores standby power to prevent unnecessary power consumption, saving energy and developing a standby power automatic shutdown and recovery device that can prevent the risk of large fires caused by leakage current.

본 논문에서는 사용하지 않는 전기제품에서 불필요하게 소비되는 대기전력을 절감하기 위한 장치를 개발하였다. 도플러 센서를 사용하여 사람이 콘센트 주변에 존재 유무에 따라 콘센트의 전원공급과 차단을 자동으로 수행하는 장치이다. 도플러 센서는 동축 케이블 트랩을 사용하여 송신 안테나를 설계하였으며 10GHz 대역의 RF신호를 방사하여 대상 물체로부터 반사된 파장이 변화된 반사파 신호를 수신부로 수신하여 물체를 감지하여 사람의 접근을 인지하도록 하였다. 대기전력을 자동으로 차단 및 복구하여 불필요한 전력소모를 방지하여 에너지를 절약하고 누설전류에 의한 대형 화재의 위험성을 방지할 수 있는 대기전력 자동 차단 및 복구 장치를 개발하였다.
