Abstract

본 발명은 무정전 전원장치에 있어서, 마이크로 프로세서를 이용하여 부하의 변동에 따라 정확하게 백업(Back-up)시간을 표시하는 방법에 관한 것으로, ups의 출력 및 부하변동에 따른 백업시간의 불일치를 해결하여 정확한 백업시간을 표시해주기 위한 것이다.The present invention relates to a method of accurately displaying a backup time according to a load change using a microprocessor in an uninterruptible power supply, and to solve the inconsistency of the backup time due to the output of the ups and the load change. This is to display the exact backup time.

본 발명은 ups의 메인루틴동작 중 정전상태가 발생한 경우 밧데리 백업상태로 전환하는 제1단계(31), 밧데리의 현재 출력전류(Idc)와 전압(Vdc)를 감지하여 상기 현재출력전류(Idc)에 따라 방전곡선을 선택하는 제2단계(32, 33), 상기 현재 출력전압(Vdc)과 방전곡선에 따라 백업시간을 결정하는 제3단계(34), 상기 결정된 백업시간을 표시하고 상기 현재출력전압이 종지전압이거나 상기 백업시간이 "0"이면 종료하는 제4단계(35, 36, 37), 및 상기 현재 출력전압이 종지전압이 아니고 상기 백업시간이 "0"이 아니면 상기 제2단계(32, 33)로 진행하는 제5단계(37)에 의해 수행되는 것을 특징으로 한다.The present invention provides a first step (31) of switching to a battery backup state when a power failure state occurs during the main routine operation of ups, and detects the current output current Idc and the voltage Vdc of the battery to the current output current Idc. A second step (32, 33) of selecting a discharge curve according to the third step (34) of determining a backup time according to the current output voltage (Vdc) and the discharge curve, and displays the determined backup time and displays the current output. A fourth step (35, 36, 37) of terminating if the voltage is the end voltage or the backup time is " 0 ", and if the current output voltage is not the end voltage and the backup time is not " 0 " 32, 33, characterized in that it is performed by a fifth step (37).
