Description

광통신 케이블을 통해 신호를 송수신하는 ＬＥＤ전광판{LED electronic light board which communicate via thereof optical cable}LED electronic light board which communicates via optical communication cable

본 발명은 LED전광판에 관한 것으로써, LED전광판의 설치된 각 LED의 발광을 제어하여 영상을 표출하는 영상제어 신호와 온도센서 등의 센서로부터 감지된 신호의 송수신을 하나의 광통신 케이블로 이루어지게 함으로서 메인콘트롤러와 LED전광판 사이의 배선과 전체 구성을 단순화시킬 수 있으며, 배선이 단순화됨으로서 제어수단과 LED전광판 사이의 거리 제한을 줄일 수 있는 광통신을 이용한 제어수단을 구비한 LED전광판에 관한 것이다. The present invention relates to an LED signboard, by controlling the light emission of each LED installed in the LED signboard to transmit and receive the image control signal and the signal sensed from a sensor such as a temperature sensor to display the image by the main optical cable The wiring and the overall configuration between the controller and the LED signboard can be simplified, and the wiring is simplified and the LED signboard is provided with a control means using optical communication that can reduce the distance limit between the control means and the LED sign.

통상적으로 소정의 광고나 표시 수단으로 전광판이 사용되고 있다. Generally, an electronic sign is used as a predetermined advertisement or display means.

이러한 전광판들중 비교적 저렴하고 제어가 용이하여 많이 사용되고 있는 것이 LED전광판이다. Among these display boards, LED displays are relatively inexpensive and easy to control.

이러한 LED전광판은 다수의 LED를 설치하여 순차적으로 또는 선택적으로 발광되게 함으로서 원하는 형상이나 문자 등이 표시되게 하는 수단으로써 소정의 수용공간을 갖는 프레임의 전면에 다수의 LED가 설치된 다수의 LED모듈을 착탈 가능 하게 설치하여 구성된다. The LED signboard is a means for displaying a desired shape or character by sequentially or selectively emitting a plurality of LEDs by attaching a plurality of LEDs, and detaching a plurality of LED modules having a plurality of LEDs installed in front of a frame having a predetermined accommodation space. It is possible to install and configure.

이러한 LED전광판의 프레임에는 상기한 바와 같이 소정의 수용공간이 형성되어 있으며, 이 공간에는 상기 LED모듈에 전원을 공급하기 위한 전원 공급 장치와 이들에 공급되는 전원을 선택적으로 제어하기 위한 제어수단을 구비하고 있으며, 배면은 상기 전원 공급 수단 및 제어 수단을 보호하기 위해 막고 도어를 설치하여 상기 전원 공급 수단 및 제어수단의 설치 및 보수 할 수 있게 구성되어 있다. A predetermined accommodating space is formed in the frame of the LED signboard as described above, and the space includes a power supply device for supplying power to the LED module and control means for selectively controlling the power supplied thereto. And, the back is configured to block and protect the power supply means and control means to install and repair the power supply means and control means by installing a door.

위와 같이 구성된 LED전광판의 구성을 도 2에 도시하였다. The configuration of the LED signboard configured as described above is shown in FIG.

도시한 바와 같이 종래의 LED전광판은 다수의 LED모듈(100)과, LED모듈에 전기를 공급하기 위한 전원공급장치(200)와, LED모듈에 구비된 LED의 점등을 제어하는 제어수단으로 구성되어 있으며, 제어수단으로는 전원공급장치, 냉각팬, 각종 센서를 제어하기 위한 서브콘트롤러(310)와, LED모듈에 구비된 스캔보드(scan board)(110)와 서브콘트롤러에 제어신호를 전송하는 메인콘트롤러(300)를 포함하여 구성되어 있다. As shown, the conventional LED signboard is composed of a plurality of LED module 100, the power supply device 200 for supplying electricity to the LED module, and the control means for controlling the lighting of the LED provided in the LED module. The control means includes a sub-controller 310 for controlling a power supply device, a cooling fan, and various sensors, and a main board for transmitting control signals to a scan board 110 and a sub-controller provided in the LED module. It is configured to include a controller 300.

이와 같이 구성된 종래의 LED전광판은 각 LED모듈(100)은 적, 녹, 청의 3원색을 발광하는 다이오드가 한 쌍을 이루고, 이러한 LED쌍을 다수 배열하여 구성되며, 메인콘트롤러의 제어신호를 각 LED모듈의 스캔보드가 각 LED로 전송하여 LED의 점멸하도록 제어된다. In the conventional LED signboard configured as described above, each LED module 100 is composed of a pair of diodes emitting three primary colors of red, green, and blue, and is configured by arranging a plurality of such LED pairs, and controlling the control signal of the main controller for each LED. The module's scanboard is sent to each LED and controlled to blink the LED.

이렇게 구성된 종래의 LED전광판은 메인콘트롤러의 제어신호를 각 모듈에 구비된 스캔보드에 전달하기 위해 많은 양의 신호 전송라인을 구비하여야 하며, 이에 따라 메인콘트롤러와 LED전광판 사이에는 많은 양의 통신케이블을 설치하여야 하 며, 이렇게 케이블의 배선이 복잡해지면 시공 할 때 혼선이 이루어질 수도 있을 뿐만 아니라 낙뢰나 전기적인 절연으로부터의 완전하지않아 LED표출부의 유도전류등이 통신라인등을 거처 메인 콘트롤러 등의 손상을 입히기도 한다. The conventional LED display board configured as described above should have a large amount of signal transmission line to transmit the control signal of the main controller to the scan board provided in each module. Accordingly, a large amount of communication cable is connected between the main controller and the LED display board. If the wiring of the cable is complicated, crosstalk may occur during construction, and the induction current of the LED emitting part may not be damaged due to lightning or electrical insulation and may damage the main controller. It can also be clothed.

그러므로 유지 보수에 많은 비용이 소모되는 단점이 있었다. Therefore, there is a disadvantage in that a large cost is required for maintenance.

또한, 이렇게 많은 양의 통신선을 배선하여야 함으로서 전광판본체와 메인콘트롤러 사이의 거리가 제한되는 문제가 있었다. In addition, there is a problem that the distance between the main body and the main board is limited by wiring such a large amount of communication lines.

또한, 이와 같이 구성된 종래의 LED전광판은 상기한 바와 같이 스캔보드가 단순히 메인콘트롤러의 제어신호를 각 LED에 전달하는 역할만을 하고, 냉각팬이나 센서가 전체 LED전광판에 하나만 구비되어 있으므로써, 각 LED모듈을 개별적으로 제어할 수 없는 문제가 있으며, 각 LED모듈을 개별적으로 제어하기 위해서는 별도의 모듈콘트롤러(120)를 설치하여야 하고, 이렇게 별도의 모듈콘트롤러를 설치할 경우 이 각각의 모듈콘트롤러와 메인콘트롤러 사이의 신호 전송을 위한 통신성이 따로 구비되어야 함으로써 더욱 구조가 복잡해지는 문제가 있었다. In addition, the conventional LED display board configured as described above merely serves to transmit the control signal of the main controller to each LED as described above, and only one cooling fan or sensor is provided in the entire LED display board. There is a problem that the module can not be controlled individually, in order to control each LED module separately, a separate module controller 120 should be installed, and if a separate module controller is installed in this way between each module controller and the main controller There is a problem in that the structure is further complicated by having to provide a separate communication for signal transmission.

본 발명은 상기와 같은 문제점을 해소하기 위해 개발된 것으로써, 하나의 광통신 케이블을 이용하여 LED를 제어하기 위한 영상신호와 주변기기 제어 신호를 전송할 수 있게 함으로서 통신선을 간소화시킬 수 있을 뿐만 아니라, 통신선을 연결시키기 위한 커넥터를 소형화시키고 수를 줄임으로서 제어기의 구성을 단순화시킬 수 있고, 광통신 케이블은 전기적으로 절연성을 갖음으로써 외부로부터의 낙뢰등이 통신선을 통해 LED부나 콘트롤러로 유입되는 것을 방지하여 보다 안정성이 있는 LED전광판을 제공함을 목적으로 한다. The present invention has been developed to solve the above problems, by using a single optical communication cable to transmit a video signal and a peripheral control signal for controlling the LED can not only simplify the communication line, but also the communication line By miniaturizing and reducing the number of connectors to be connected, the configuration of the controller can be simplified, and the optical communication cable is electrically insulated, thereby preventing lightning from entering the LED unit or the controller through the communication line. An object of the present invention is to provide an LED sign.

더욱이, 각 LED모듈마다 센서와 냉각팬을 구비하고, 콘트롤러를 구비한 스캔보드를 설치하여 구성함으로서 각 LED모듈을 개별적으로 제어할 수 있게 한 광통신 케이블을 통해 신호를 송수신하는 LED전광판을 제공함을 목적으로 한다. Furthermore, the purpose of the present invention is to provide an LED display board that transmits and receives a signal through an optical communication cable that includes a sensor and a cooling fan for each LED module, and a scan board equipped with a controller to control each LED module individually. It is done.

이러한 본 발명의 케이블을 통해 신호를 송수신하는 LED전광판은 LED가 다수의 설치되고, 모듈콘트롤러를 구비한 스캔보드가 장착된 다수의 LED모듈과 ; 상기 LED의 점등 및 주변기기의 구동에 필요한 전원을 공급하는 전원공급장치와 ; 광통신 케이블에 의해 상기 스캔보드와 연결되어 제어신호를 송수신하며, 상기 LED모듈에 설치된 각 LED의 점멸을 제어하는 메인콘트롤러와 ; 상기 메인콘트롤러와 광통신 케이블로 연결되어 있으며, 상기 전원공급장치를 제어하는 서브콘트롤러를 포함하여 구성된다. LED display board for transmitting and receiving signals through the cable of the present invention is a plurality of LED is installed, a plurality of LED modules equipped with a scan board having a module controller; A power supply device for supplying power for lighting the LED and driving the peripheral device; A main controller connected to the scan board by an optical communication cable to transmit and receive a control signal, and to control the blinking of each LED installed in the LED module; It is connected to the main controller by an optical communication cable, and comprises a sub-controller for controlling the power supply.

본 발명은 하나의 광통신 케이블을 이용하여 LED를 제어하기 위한 제어신호뿐만 아니라 주변기기를 제어하기 위한 제어신호를 송수신할 수 있게 함으로서 LED전광판에 설치된 모듈콘트롤러와 외부에 설치된 메인콘트롤러 사이의 통신선의 배 선을 간소화를 시킬 수 있어 전광판의 제작이 용이할 뿐만 아니라 제작비용을 절감할 수 있는 효과가 있다. The present invention enables the transmission and reception of a control signal for controlling an LED as well as a control signal for controlling a peripheral device using a single optical communication cable to connect a communication line between a module controller installed in an LED display board and an external main controller. Since it is possible to simplify the manufacturing of the electric signboard, it is easy to reduce the production cost.

또한, 통신선이 간소화됨으로서 통신선의 배선이 용이하여 전광판 본체와 메인콘트롤러 사이의 거리 제약이 줄어 보다 안전한 장소에 메인콘트롤러를 설치하고 이를 용이하게 제어할 수 있는 효과도 있다. In addition, since the communication line is simplified, wiring of the communication line is easy, thereby reducing the distance restriction between the main body and the main controller, so that the main controller can be installed in a safer place and easily controlled.

또한, 각 LED모듈마다 센서와 냉각팬을 설치하고, 스캔보드에 콘트롤러를 구비하여 LED는 물론 각종 주변기기를 개별적으로 제어할 수 있게 함으로써 각 모듈의 관리를 보다 용이하게 할 수 있는 효과가 있다. In addition, by installing a sensor and a cooling fan for each LED module, and equipped with a controller on the scan board, it is possible to individually control not only the LED but also various peripheral devices, thereby making it easier to manage each module.

또한, 광통신 케이블은 전기적으로 절연을 이루고 있으므로 통신선을 따라 낙되 등의 외부의 전기 충격이 LED부와 콘트롤러로 유입되어 제어신호에 노이즈가 발생되는 것을 방지할 수 있을 뿐만 아니라, 전기적인 충격이나 낙뢰 등으로부터 메인콘트롤러와 각각의 보드들을 보호할 수 있는 효과가 있다.In addition, since the optical communication cable is electrically insulated, external electric shocks such as falling down along the communication line flow into the LED unit and the controller to prevent noise from occurring in the control signal, as well as electric shocks and lightning strikes. It is effective to protect the main controller and each board from the board.

이하, 본 발명에 따른 광통신 케이블을 통해 신호를 송수신하는 LED전광판을 첨부된 도면을 참조하여 상세하게 설명한다. Hereinafter, with reference to the accompanying drawings of the LED display board for transmitting and receiving signals through the optical communication cable according to the present invention will be described in detail.

The LED display board which transmits and receives a signal through one optical communication cable of the present invention transmits and receives an LED flashing control signal and a control signal for controlling a peripheral device such as a temperature sensor or a cooling fan using the optical communication cable.

이렇게 하나의 광통신 케이블로 두 종류의 제어신호를 송수신하기 위한 본 발명에 따른 광통신 케이블을 통해 신호를 송수신하는 LED전광판은 LED가 다수의 설치되고, 모듈콘트롤러(11a)를 구비한 스캔보드(11)가 장착된 다수의 LED모듈(1)과 ; 상기 LED의 점증에 필요한 전원을 공급하는 전원공급장치(2)와 ; 광통신 케이블에 의해 상기 스캔보드(11)와 연결되어 제어신호를 송수신하며, 상기 LED모듈(1)에 설치된 각 LED의 점멸을 제어하는 메인콘트롤러(3)와 ; 상기 메인콘트롤러(3)와 광통신 케이블로 연결되어 있으며, 상기 전원공급장치(2)를 제어하는 서브콘트롤러(31)를 포함하여 구성된다. Thus, the LED board for transmitting and receiving signals through the optical communication cable according to the present invention for transmitting and receiving two types of control signals with one optical communication cable is installed a plurality of LED, the scan board 11 having a module controller (11a) A plurality of LED modules (1) equipped with; A power supply device 2 for supplying power required for the increase of the LED; A main controller (3) connected to the scan board (11) by an optical communication cable to transmit and receive a control signal, and to control the blinking of each LED installed in the LED module (1); It is connected to the main controller 3 and the optical communication cable, and comprises a sub-controller 31 for controlling the power supply (2).

상기 LED모듈(1)은 통상적인 LED전광판을 구성하는 LED모듈과 동일 또는 유사하게 구성되어 있으나, 상기한 바와 같이, 메인콘트롤러(3)와 광통신 케이블로 연결된 스캔보드(11)가 설치되어 있다. The LED module 1 is configured in the same or similar to the LED module constituting a conventional LED display board, as described above, the scan board 11 is connected to the main controller 3 and the optical communication cable is installed.

상기 스캔보드(11)는 메인콘트롤러(3)의 제어신호를 각 LED로 전달하는 역할을 하는 것이나, 본 발명에서는 이러한 신호의 전달 기능에 온도센서의 온도감지신호를 메인콘트롤러로 전달하고, 냉각팬의 구동을 제어하는 모듈콘트롤러(11a)를 설치하여 구성된 것으로 모듈콘트롤러(11a)는 마이크로프로세서로 구성된다.

The control signal transmitted from the main controller (3) is a signal for controlling the blinking of each LED to display a picture or text generated through a graphic program stored in a computer on the electronic display as shown, which is a conventional LED display and Same is similar.

즉, 본원 발명의 요지는 상기한 바와 같이 하나의 광통신 케이블을 이용하여 LEd 제어신호와 주변기기 제어신호를 동시에 전송할 수 있게 한 것이며, 이렇게 LED 제어신호와 주변기기의 제어신호를 전송하는 광통신 케이블로 전송되는 제어신호의 포맷은 RS485인터페이스 포맷을 사용한다.
