본 발명은 무인경보시스템을 이용한 전원제어시스템 및 그 제어방법에 관한 것으로서, 더욱 상세하게는 무인경보시스템의 작동신호 또는 해제신호에 따라 무인경보시스템이 설치된 건물 실내와 같은 특정한 장소에 상용교류전원의 공급을 자동으로 단속함으로써 야간의 대기전력 낭비를 줄임과 함께 전기누전 등으로 인한 사고를 예방할 수 있는 무인경보시스템을 이용한 전원제어시스템 및 그 제어방법에 관한 것이다.The present invention relates to a power supply control system using the unmanned alarm system and a control method thereof. More particularly, the present invention relates to the use of a commercial AC power supply in a specific place, such as a building interior, in which an unmanned alarm system is installed according to an operation signal or a release signal of an unmanned alarm system.

일반적으로 기업 사무실, 은행, 관공서 등과 같은 건물 내에는 수많은 근무자들이 업무를 보게 되며 그에 따라 다양한 전기기기들이 사용되고 있는데, 이러한 전기기기들은 전원이 오프(Off)된다 하더라도 플러그가 콘센트에 연결되어 있는 상태에서는 일정량의 대기전력(Standby Power)을 소모하게 된다.In general, a large number of workers work in buildings such as corporate offices, banks, and government offices, and various electric devices are used. These electric devices are used when the plug is connected to the outlet even when the power is turned off. It consumes a certain amount of standby power.

따라서 불필요한 대기전력의 낭비를 줄여 에너지를 절감하기 위해서는 퇴근이나 외출을 할 때 사용하던 전기기기의 전원만을 오프(Off)시키는 것으로는 불충분하며 플러그까지 콘센트에서 뽑아 줄 필요가 있는 것이다.Therefore, in order to save energy by reducing unnecessary waste of standby power, it is not enough to turn off only the power of the electric equipment used when going home or going out, and it is necessary to unplug the plug.

그러나 대부분의 경우에 퇴근이나 외출을 하면서 이와 같이 사용하던 전기기기의 플러그를 뽑는 경우는 매우 드문 것이 현실이며, 그에 따라 국가적인 차원에서 볼 때 해마다 엄청난 양의 에너지가 무의미하게 소모되는 문제점이 있는 바, 이러한 대기전력의 낭비를 획기적으로 줄이기 위한 기술 개발이 절실히 요구된다고 할 것이다.However, in most cases, it is very rare to unplug such electric devices while going home from work or going out, and accordingly, there is a problem that huge amounts of energy are consumed insignificantly every year at the national level.
