In this paper, the automatic standby power blocking socket outlet to reduce standby power by blocking power threshold is implemented. Where, the standby power means a flowing power when a disused power electronic is plugged into the socket outlet. The proposed socket outlet can cut off the standby power by establishing a proper block power threshold electronic device according to each electronic device because it can monitor the amount of power through the smart machines such as the real-time PC or mobile phone and directly control the blocking power threshold. The software is implemented by using Visual Studio software, code vision and SN8 C studio, and the hardware is embodied in ATmega128, SN8F27E93S, USB to UART, and relay etc. Through the simulation, we find that the standby power of the proposed method is similar to that of the conventional method in case of the cellular phone but the standby power of the proposed method is much less than that of the conventional method in case of the computer, air conditioning, and set-top box. Therefore, it is proved that the proposed socket outlet has a superior performance in terms of the standby power.

A device which could cut off the consumption of standby power by electric or electronic devices at homes and offices while waiting for a command to carry out the main functions from the inside or the outside was developed at a low price. Efforts to save standby power have been made on a global scale as well as by advanced countries. The consumption of standby power in South Korea is also increasing gradually due to increasing trend in the number of electronic and electric devices per household, becoming a major factor for waste of electric energy. The previous standby power cutoff devices themselves have high electric energy consumption and complicated structures, making the purpose less meaningful. Therefore, a low-priced standby power cutoff device is suggested in this study, which compensates such problems and cuts off the consumption of standby power completely. The circuit of the suggested standby power cutoff device was designed and implemented by applying it to an earth leakage breaker and an (electrical) outlet. Experimental results show its superiority.

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 논문은 유도가열 조리기 회로에서 대기시 사용되는 전력 절감방법을 제안한다. 고안된 제어 방식은 주 전원 라인에 Relay를 추가하여 대기시 주 인버터 회로 전력 소비를 차단하고, 보조전원으로 사용하는 SMPS의 다출력중 대기시 사용되지 않는 출력들을 Relay를 이용하여 제어함으로써 차단하는 방법이다. 제안된 방법으로 대기시 소비되는 전력을 1W 미만으로 절감하고, 이를 회로에 적용하여 대기전력을 측정하였다.

Modem consumer electronic products like TV, VCR etc, offer users the convience of switching the equipment on and off via a remote control handset. When this type of equipments is switched off, it is said to be in standby mode. In this paper, We proposed that the method of the blocking standby power from in industrial product including electronic and electronic appliauces. This method is perfectly blocking the standby power of electrical circuit.

In this research, the electric power consumptions of the electrical machinery and appliances selected in the Seoul division of Korea Electrical Safety Corporation were measured. The power-saving efficiency was investigated by comparing the amounts of the reserved electric power when the Saver was on or off through measuring that of the reserved electric power before and after equipping the selected appliances with the Saver, a cutoff of the reserved electric power. As a result, the power-saving efficiency was around 18% when the Saver was installed. It can be ascribed to the removal of the source wasting electrical energy. Furthermore, by blocking the reserved electric power, the electric fire can be originally prevented and also the life time of the electrical machinery and appliances can be postponed.

본 논문에서는 전기전자 기기가 외부전원에 연결된 상태에서 그 주 기능을 수행하지 않거나 내부 혹은 외부로 부터 주 기능 수행을 위한 명령을 기다리고 있는 상태에서 소모하는 대기전력(Standby Power)을 저감할 수 있는 장치를 개발하고자 하였다. 기존의 멀티탭 형대기전력 차단장치는 그 장치 자체의 소비전력이 커서 사용 의미를 퇴색시키는 문제점을 안고 있다. 본 논문에서는 기존 제품의 이러한 문제점을 보완시키고 대기전력을 획기적으로 감시킬 수 있는 멀티탭 형식의 외장형 대기전력 차단장치와 가전기기 내장형 차단장치의 회로를 설계 및 구현하고 비교 실험을 통하여 그 우수성을 확인하였다.

In this paper, we describe the design and implementation of wireless smart plug having AC power sensor and intelligent standby power control algorithm for energy sensor network. The adaptive standby power control algorithm has function to apply different threshold of standby power by using learning algorithm depending on electric equipments. As using the proposed algorithm, user convenience will be more better and power consumption can be more reduced. The implemented prototypes of wireless smart plug and wireless access point were tested to verify the required functions and performance. As a result, we confirmed practicality of wireless smart power sensor and satisfaction of given design specifications.

본 논문은 가정에서 사용되는 가전기기의 대기전력을 사용자의 위치에 따라 자동으로 제어하는 시스템을 설계 및 구현한다. 현재 사용되고 있는 대기전력 제어 시스템의 대부분은 사용자의 임의에 의해 On/Off 제어를 수행하거나 일정시간 해당 가전기기의 사용이 이루어지고 있지 않는 상태를 자동감지하여 대기전력을 차단하는 형태로 이루어져 있다. 그러나 이러한 시스템들은 사용자의 개입에 의해 수동으로 재가동해야 하므로 기기 사용자의 불편함을 초래하고 있다. 또한, 전체의 재실을 감지하여 모든 구역의 대기전력을 차단 혹은 해제하는 시스템의 경우는 모든 구역의 대기전력을 사용자 부재시까지 모두 해제하게 되므로 이로 인한 에너지 낭비를 초래하게 된다. 이에 본 논문은 재실자의 구역에 따라 미사용 가전기기들의 대기전력을 자동으로 On/Off 제어할 수 있는 사용자 위치에 기반한 대기전력 제어 시스템을 제안한다.

A Power Management System(PMS), which provides the functions of automatic detection and cutoff of home appliances' standby power without user intervention, is presented in this paper. A client in this system measures the power consumption of a home appliance plugged in it and transmits the information to a server in real-time over a wireless network. The server analyzes the features of the power consumption of home appliances and detects if any home appliance consumes standby power. The detected standby power information is used to create the information of the home appliance and to build a database, which will finally offer the automatic detection and cutoff of the standby power without any configuration through user intervention.
