The LED lamp 13 is provided with a power detection unit 14 for detecting whether the power supply is abnormal.

여기서, 상기 광분배기(11), 백라이트(12), LED 램프(13)는 상기 전원감지부(14)에 의해서만이 아니라, 각각 개별적으로 상기 제어부(10)에 의해 그들의 전원이상 여부가 감지되고 제어될 수 있다. Here, the light splitter 11, the backlight 12, and the LED lamp 13 are not only detected by the power detecting unit 14, but are individually sensed and controlled by the control unit 10, respectively.

또한, 외부로부터 LCD화면조정을 위한 리모콘신호를 수신하는 리모콘신호수신부(15)와, 상기 제어부(10)로부터 화면조정용 제어신호를 수신하여 화면조정을 수행하기 위한 LCD모듈(16)이 구비된다. 이때, LCD표시장치들의 디스플레이 상태가 정상적이지 못할 경우에 일차적으로 관리자는 리모콘을 이용하여 색상, 명암, 기기번호를 입력하여 디스플레이 상태의 정상화를 기하고자 할 때, 상기 제어부(10)는 LCD모듈(16)로 화면조정용 제어신호를 출력하여 리모콘신호에 따라 화면 조정값을 색상별, 명암별로 변경하도록 명령하고, 상기 LCD모듈(16)은 화면조정용 제어신호에 따른 변경명령을 수행한다. 이러한 LCD화면조정은 LCD 기기별로 선택할 수도 있고, 전체 LCD기기를 선택할 수도 있도록 함으로써 관리편의성을 기하도록 하는 것이 바람직하다.In addition, a remote control signal receiving unit 15 for receiving a remote control signal for adjusting the LCD screen from the outside, and the LCD module 16 for receiving a screen control control signal from the control unit 10 to perform the screen adjustment. At this time, when the display state of the LCD display devices is not normal, when the administrator first tries to normalize the display state by inputting color, contrast, and device number by using a remote controller, the controller 10 includes an LCD module ( 16) and outputs a screen adjustment control signal to change the screen adjustment value for each color and contrast according to the remote control signal, and the LCD module 16 performs a change command according to the screen adjustment control signal.

한편, 상기 전원감지부(14)의 세부구성 및 동작흐름을 살펴보면 다음과 같다.On the other hand, the detailed configuration and operation flow of the power detection unit 14 is as follows.

도 2는 도 1에 도시된 전원감지부(14)의 세부구성을 설명하기 위한 블록도로서, 상기 전원감지부(14)는 광분배기(11), 백라이트(12), LED(13) 즉, 감지대상체(143)의 전원공급라인에 전류량을 측정하기 위한 전류측정기(141)와, 전류측정기(141)에서 측정된 전류량이 소정의 기준 전류량에 미치는지 여부를 판단하여 가부를 출력하는 감지기(142)로 구성되어 있다.FIG. 2 is a block diagram illustrating a detailed configuration of the power detector 14 shown in FIG. 1. The power detector 14 includes an optical splitter 11, a backlight 12, and an LED 13. The current measuring unit 141 for measuring the amount of current in the power supply line of the sensing object 143 and the detector 142 determining whether or not the amount of current measured by the current measuring unit 141 reaches a predetermined reference current amount. Consists of

또한, 상기 전원감지부(14)는 감지대상체(143)별로 한 쌍의 전류측정기(141) 및 감지기(142)를 가지게 되는데, 광분배기(11), 백라이트(12), LED(13)는 열차 내에 매우 많은 수량이 설치되므로, 전체적으로 매우 많은 쌍의 전류측정기(141)와 감지기(142)로 구성된다.In addition, the power detecting unit 14 has a pair of current measuring units 141 and detectors 142 for each sensing object 143. The optical splitter 11, the backlight 12, and the LED 13 are trains. Since a very large quantity is installed in the interior, it is composed of a large number of pairs of current measuring instruments 141 and detectors 142.

이때, 상기 감지기(142)는 감지대상체(143) 즉, 광분배기(11), 백라이트(12), LED(13) 별로 정상적인 전류량이 서로 다르므로 상기 기준 전류량 또한 서로 다르게 설정되고, 이 기준 전류량은 감지기(142) 내부의 메모리에 디지털값으로 저장된다.In this case, the detector 142 is different from the normal current amount by the sensing object 143, that is, the light splitter 11, the backlight 12, and the LED 13, and thus the reference current amount is set differently, and the reference current amount is It is stored as a digital value in the memory of the detector 142.

이러한 전류측정기(141) 및 감지기(142) 즉, 전원감지부(14)와 이에 따른 제어부(10)의 동작흐름을 순시(瞬時)적으로 살펴보면 다음과 같다.Looking at the instantaneous flow of operation of the current measuring unit 141 and the detector 142, that is, the power detector 14 and the control unit 10 according to the instant.

먼저, 전류측정기(141)는 감지대상체(143)로 인해 소요되는 전류량을 실시간 으로 측정하고, 측정된 현재의 전류값은 상기 감지기(142)로 전달되며, 감지기(142)는 현재의 전류값이 내부에 저장된 전류값과 비교해서 어느 값이 큰지를 출력한다. 즉, 저장된 전류값에서 현재의 전류값을 마이너스(-)연산(빼기)을 수행하여 그 결과가 플러스(+) 또는 제로(0) 수치이면 감지대상체는 전원상 이상이 없는 것이지만, 마이너스 수치이면 전원상 이상이 발생한 것이므로 이를 전달받은 제어부(10)는 무선통신부(18) 혹은 네트웍통신부(19)를 통해서 지정된 곳으로 전원이상이 발생된 기기의 번호 및 위치를 전송하게 된다. First, the current meter 141 measures the amount of current required by the sensing object 143 in real time, and the measured current value is transmitted to the detector 142, and the detector 142 is configured to have a current value. It outputs which value is big compared with the current value stored inside. That is, if the current value is minus (-) operation from the stored current value and the result is positive (+) or zero (0) value, the sensing object has no power phase error. Since an abnormality has occurred, the controller 10 receiving the abnormality transmits the number and location of the device having the power failure to the designated place through the wireless communication unit 18 or the network communication unit 19.
