Abstract
본 발명은 이중화장치에서 전원 공급시 원하는 장치를 동작장치로 선택하고, 이중화 로직 절체시 서로 제어권을 넘겨주는 발진 현상을 방지하는 회로를 제공한다. 이를 위하여 초기전원공급시 리세트부의 출력과 공급전원을 이용하여 동작장치 및 대기장치를 설정하므로서, 초기전원 공급시점에서 발생되는 제어권의 발진 현상을 제거한다. 이후 상대장치의 동작상태를 감시하여 제어권을 절체하여야 하는 경우 상대 장치가 에러상태이면 제어권을 넘기지 않으므로서, 제어권의 발진현상을 방지한다.The present invention provides a circuit for selecting a desired device as an operation device when supplying power from a redundant device, and preventing oscillation phenomena that give control to each other when the redundant logic is switched. To this end, by setting the operating device and the standby device using the output of the reset unit and the supply power at the initial power supply, the oscillation phenomenon of the control right generated at the initial power supply is eliminated. Then, when the control right is to be transferred by monitoring the operation state of the counterpart device, if the counterpart device is in an error state, the control right is not passed, and the oscillation of the control right is prevented.
