Abstract

본 발명은 엔진시동전에 계기판에 구비되어 있는 복수의 경고등의 전구에 대한 이상여부를 진단하여 이상이 발생한 경고등을 운전자에게 알려주도록 한 경고등 전구 고장진단표시장치를 제공하기 위한 것이다.The present invention provides a warning lamp failure diagnosis display device that diagnoses an abnormality of a plurality of warning lamps provided on an instrument panel before starting an engine and informs a driver of an abnormality warning lamp.

이를 위해 본 발명은, 점화스위치(30)가 온됨에 따라 복수의 경고등 내의 전구(50a∼50i)를 순차적으로 점등시켜 고정여부를 체크한 후 고장난 전구의 경고등에 대한 표시동작이 행해지도록 제어하는 제어부(40)와, 상기 다수개의 전구(50a∼50i)에서 송출하는 광신호를 각각 전기적 신호로 변환하여 출력하는 다수개의 포토 다이오드(50a'∼50i'), 상기 포토 다이오드(50a'∼50i')에서 출력되는 전기적 신호에 반응하여 각 전구의 점등에 따른 고유의 신호를 상기 제어부(40)로 인가하는 다이오드 매트릭스(55), 상기 제어부(40)로부터 표시제어신호를 해석하는 디코더(60), 상기 디코더(60)로부터의 신호를 기초로 고장난 해당 전구의 경고등의 번호를 표시하기 위한 표시구동부(70) 및, 상기 표시구동부(70)에 의해 고장난 전구의 경고등을 표시하는 표시부(80)를 포함하여 구성되고, 상기 제어부(40)는 점등제어한 전구에 대한 점등신호가 상기 다이오드 매트릭스(55)를 통해 정상적으로 입력되지 않으면 고장으로 인식하는 것을 특징으로 하여, 이상이 발생한 경고등을 운전자에게 알려줌으로써, 차량 각부분의 이상유무에 대한 좀 더 정확한 정보를 운전자에게 제공하므로, 운행중에 발생할 수 있는 안전사고를 사전에 방지할 수 있다.To this end, according to the present invention, as the ignition switch 30 is turned on, the lamps 50a to 50i in the plurality of warning lamps are sequentially turned on to check whether or not the lamps are stationary, A plurality of photodiodes 50a 'to 50i' for converting optical signals emitted from the plurality of bulbs 50a to 50i into electrical signals and outputting the electrical signals, A diode matrix 55 for applying a unique signal according to lighting of each bulb to the control unit 40 in response to an electrical signal output from the control unit 40, a decoder 60 for analyzing a display control signal from the control unit 40, A display driving unit 70 for displaying the number of the warning lamp of the corresponding bulb that has failed based on a signal from the decoder 60 and a display unit 80 for displaying a warning lamp of the bulb that has been broken by the display driving unit 70 And the control unit 40 recognizes that the lighting signal for the lamp controlled by the lighting is not normally inputted through the diode matrix 55. In this case, Providing the driver with more accurate information about the abnormality of each part makes it possible to prevent safety accidents that may occur during operation.
