Abstract
원격 제어 유니트의 배터리 감시장치는 충전회로(C160)가 방전상태로부터 정해진 레벨까지 충전되는데 걸리는 시간을 측정한다. 약해진 배터리는 충전회로를 정해진 레벨까지 충전시키는데 완전히 충전된 배터리에 비해 더 많은 시간이 걸린다. 완전히 충전된 배터리의 충전시간이 기록된 후속하는 충전시간 측정값과 비교된다. 기록된 충전시간과 현재 측정된 충전시간간의 차이가 정해진 값을 초과할 때 약해진 배터리에 대한 경고신호가 발생된다. 일실시예에서, 경고신호는 가시 LED(VLED)에 공급되고, 다른 실시예에서는 사용자에게 경고하는 제어장치에 전송된다.The battery monitoring device of the remote control unit measures the time taken for the charging circuit C160 to charge from the discharge state to the predetermined level. A weaker battery takes more time than a fully charged battery to charge the charging circuit to a predetermined level. The charge time of a fully charged battery is compared to the subsequent charge time measurement recorded. When the difference between the recorded charging time and the currently measured charging time exceeds a predetermined value, a warning signal is generated for the weakened battery. In one embodiment, the warning signal is supplied to a visible LED (VLED), and in another embodiment is sent to a control device that alerts the user.
