The display method includes a step-by-step display in the form of stacked bricks and a method of adjusting the number of solar displays according to the input voltage level by multiple solar displays.
따라서 본 발명의 일 실시예를 제2, 3, 4도를 참조하여 상세히 설명한다.Therefore, an embodiment of the present invention will be described in detail with reference to FIGS. 2, 3, and 4.
태양전지부(214)로부터 공급되는 동작전압은 저전압검출부(218)의 저항(R1, R2)에 의해 분압되며, 상기 저항(R2)에 분압되는 전압은 상기 태양전지부(214)로부터 공급되는 전압이 하강함에 비례하여 감소된다. 상기 저항(R2)에 분압된 전압은 A/D변환기(212)로 입력되며, 상기 A/D변환기(212)는 입력되는 전압에 따라 설정된 전압레벨 단계에 해당하는 레벨값을 가지는 저전압검출신호를 제어부(210)로 송출한다. 따라서, 제어부(210)는 제3도의 310단계에서 상기 저전압 검출부(218)로부터 입력되는 저전압검출신호가 변화된 전압레벨을 나타내는가를 판단한다. 상기 310단계에서 변화된 전압레벨을 나타내는 저전압검출신호가 입력되면 상기 제어부(210)는 312단계에서 무선호출기가 정상동작을 할 수 없는 저전압인가를 판단한다. 상기 312단계에서 저전압이 아니라 판단되면 상기 제어부만 상기 312단계에서 저전압레벨이라 판단되면 상기 제어부(211)는 스피커(216)를 제어하여 설정시간 동안 경보음을 송출한다. 또한 상기 제어부(210)는 일반전지(220)를 통하여 동작전압을 공급하도록 스위치(SW1)로 제어신호(CS1)를 송출한다. 그리고 상기 제어부(210)는 318단계에서 상기 표시부(112)를 제어하여 전압레벨 표시(410)의 LCD를 모두 오프시킴으로 저전압레벨임을 표시한다. 일반전지(220)로부터 동작전압이 공급되는 상황에서 상기 제어부(210)는 320단계에서 태양전지부(214)에 전압이 완벽하게 충전되었는가를 판단한다. 상기 320단계에서 전압충전이 완료되었다고 판단되면 상기 제어부(210)는 322단계에서 상기 스위치(SW1)를 절체하여 태양전지부(214)로부터 동작전압이 공급되도록 스위치제어신호(CS1)를 송출한다. 또한 상기 제어부(210)는 상기 표시부(112)를 제어하여 상기 전압레벨 표시(410)의 LCD를 모두 온시킴으로 완전한 충전이 이루어졌음을 표시한다.The operating voltage supplied from the solar cell unit 214 is divided by the resistors R1 and R2 of the low voltage detection unit 218, and the voltage divided by the resistor R2 is the voltage supplied from the solar cell unit 214. This decreases in proportion to the drop. The voltage divided by the resistor R2 is input to the A / D converter 212, and the A / D converter 212 receives a low voltage detection signal having a level value corresponding to a voltage level step set according to the input voltage. It transmits to the control part 210. Therefore, the controller 210 determines whether the low voltage detection signal input from the low voltage detection unit 218 indicates the changed voltage level in step 310 of FIG. 3. When the low voltage detection signal indicating the changed voltage level is input in step 310, the controller 210 determines whether the pager is low voltage that cannot operate normally in step 312. If it is determined that the low voltage level is not determined in step 312, if only the controller is determined to be a low voltage level in step 312, the controller 211 controls the speaker 216 to transmit an alarm sound for a set time. In addition, the controller 210 transmits a control signal CS1 to the switch SW1 to supply an operating voltage through the general battery 220. In addition, the controller 210 controls the display unit 112 to turn off all of the LCDs of the voltage level display 410 to display the low voltage level (318). In a situation where the operating voltage is supplied from the general battery 220, the controller 210 determines whether the voltage is completely charged in the solar cell unit 214 in step 320. If it is determined in step 320 that the voltage charging is completed, the control unit 210 transfers the switch control signal CS1 so that the operating voltage is supplied from the solar cell unit 214 by switching the switch SW1 in step 322. In addition, the controller 210 controls the display unit 112 to turn on all the LCDs of the voltage level display 410 to indicate that complete charging has been made.
상술한 바와 같이 본 발명은 일반전지를 예비용으로 사용하여 일반전지의 소모량을 줄이므로 일반전지 1개로 기존의 2배 이상의 사용시간을 얻을 수 있는 효과가 있다.As described above, since the present invention reduces the consumption of the general battery by using the general battery as a spare, it is possible to obtain the use time more than twice as much as the conventional battery.
