Zusammenfassung: | The present invention relates to a power phase detection device, system and method. According to the present invention, the power phase detection device includes: a power line communication unit on a receiving unit side, which receives power, is installed in a portion consuming power in a certain phase, and receives a phase detection signal transmitted at a time of zero crossing of a specific phase through power line communication; a timer which measures a time difference between a time point at which the phase detection signal is received and a time point at which the random phase crosses zero; and a phase detection unit configured to detect which phase the random phase is by using the measured time difference. Accordingly, it is possible to accurately detect the power supply phase with a simple configuration.
본 발명은 전원상 검출 장치, 시스템 및 방법에 관한 것으로서, 본 발명에 따른 전원상 검출 장치는, 전력을 공급받아 임의 상의 전력을 소비하는 부분에 설치되며, 전력선 통신을 통해 특정 상(phase)의 제로크로싱(Zero Crossing) 시점에서 송출된 상검출 신호를 수신하는 수용부측 전력선 통신부; 상기 상검출 신호가 수신된 시점과 상기 임의 상의 제로크로싱 시점 사이의 시간차를 측정하는 타이머; 및 측정된 상기 시간차를 이용해 상기 임의 상이 어떤 상인지를 검출하는 상 검출부;를 포함하는 것을 특징으로 한다. 이에 따라, 간단한 구성으로 전원상을 정확하게 검출하는 것이 가능하다. |
