이하, 본 발명의 구체적인 실시예에 대하여 도면을 참조하여 상세하게 설명하기로 한다.Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.
도 1은 본 발명의 바람직한 실시예에 따른 터널 내외의 휘도 분석을 통한 터널출입구 부분의 밝기 조절장치를 개략적으로 도시한 시스템 구성도이다.BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a system configuration diagram schematically illustrating an apparatus for adjusting a brightness of a tunnel entrance through brightness analysis in and out of a tunnel according to a preferred embodiment of the present invention; FIG.
도 1을 참조하면, 본 발명에 따른 터널출입구 부분의 밝기 조절장치는 터널 내부 및 외부에 설치되어 휘도를 측정하는 휘도계와 상기 휘도계로부터 측정된 휘도를 분석하여 휘도 편차를 산출하여 터널 내의 적정 휘도를 산출하는 휘도 산출부와 상기 휘도 산출부를 통해 산출된 휘도에 따라 터널 내의 조명 기구의 밝기를 제어하는 조명 제어부를 포함하여 구성될 수 있다.Referring to FIG. 1, the brightness controller of the entrance of a tunnel according to the present invention includes a brightness meter for measuring brightness and a brightness meter for measuring the brightness of the tunnel, And a lighting control unit for controlling the brightness of the lighting device in the tunnel according to the brightness calculated through the brightness calculation unit.
상기 휘도계는 터널 외부에 설치되어 터널 외부의 휘도를 측정하는 제 1 휘도계와 터널 내부에 설치되어 터널 내부의 휘도를 측정하는 제 2 휘도계를 포함하여 구성될 수 있다.The luminance meter may include a first luminance meter installed outside the tunnel for measuring the luminance outside the tunnel, and a second luminance meter installed inside the tunnel for measuring the luminance inside the tunnel.
여기서, 상기 휘도계는 CCD 카메라를 이용한 등가 광막 휘도법 또는 L20법에 의해 휘도를 측정할 수 있다.Here, the luminance meter can measure the luminance by the equivalent optical film luminance method using the CCD camera or the L20 method.
상기 제 1 휘도계 및 제 2 휘도계는 정확한 휘도 측정을 위해 각각 2개 이상의 휘도계가 설치되어 평균값으로 휘도를 산정할 수 있다.In the first and second luminance meters, two or more luminance meters may be provided for accurate luminance measurement, and the luminance may be calculated as an average value.
상기 휘도 산출부는 상기 제 1 휘도계와 제 2 휘도계로부터 측정된 휘도 정보를 수신받아 휘도 편차를 산출하고, 터널 내의 적정 휘도를 산출하는 역할을 담당한다.The luminance calculator receives the luminance information measured from the first luminance meter and the second luminance meter, calculates a luminance deviation, and calculates a proper luminance in the tunnel.
터널 내외의 휘도 차이가 기준 휘도차 이내인 경우에는 터널 내의 조명기구의 밝기를 조절할 필요가 없지만, 상기 기준 휘도차를 벗어나게 차이가 나는 경우에는 터널 내의 조명기구의 밝기를 조절할 필요가 있다.When the difference in brightness between the inside and outside of the tunnel is within the reference luminance difference, it is not necessary to adjust the brightness of the lighting device in the tunnel. However, if the difference is deviated from the reference luminance difference, the brightness of the lighting device in the tunnel needs to be adjusted.
여기서, 상기 기준 휘도차는 운전자에게 시각적 방해를 일으키지 않는 휘도의 차이를 의미하고, 실험 데이터에 의해 설정될 수 있는 값이다.Here, the reference brightness difference means a difference in brightness that does not cause a visual disturbance to the driver, and is a value that can be set by experiment data.
상기 휘도 산출부가 상기 기준 휘도차를 벗어나는 것으로 판단한 경우, 상기 조명 제어부는 터널 내의 조명 기구의 밝기를 한단계 높이도록 조절한다.When it is determined that the brightness calculating section deviates from the reference brightness difference, the lighting control section adjusts the brightness of the lighting apparatus in the tunnel to be one step higher.
여기서, 상기 조명 기구는 밝기를 단계 별로 제어할 수 있는 디밍 제어 기능을 지원하는 조명등으로 구성될 수 있으며, 이에 따라 조명 기구의 조도를 단계별로 제어할 수 있다.Here, the lighting apparatus may be configured as an illumination lamp that supports a dimming control function capable of controlling the brightness in steps, thereby controlling the illuminance of the lighting apparatus in stages.
상기와 같이 조명 제어부가 터널 내의 조명기구의 밝기를 한단계 높이도록 제어한 후 제 2 휘도계가 터널 내의 휘도값을 측정하고, 휘도 산출부는 터널 내외의 휘도값을 분석하여 기준 휘도차 범위내인지를 다시 판단하고, 여전히 기준 휘도차 범위를 벗어나는 경우 상기 조명 제어부에 이를 통지하고, 상기 조명 제어부는 터널 내의 조명 기구의 조도를 다시 한단계 높이도록 조절하는 과정을 기준 휘도차 범위 이내가 될때까지 반복하여 터널 내의 조명기구의 조도를 조절하게 된다. After the illumination control unit controls the brightness of the illumination device in the tunnel to be one step higher as described above, the second luminance system measures the luminance value in the tunnel, and the luminance calculation unit analyzes the luminance value inside and outside the tunnel to determine whether it is within the reference luminance difference range The lighting control unit repeats the process of adjusting the illuminance of the lighting apparatus in the tunnel one step higher than the reference luminance difference range until it is within the reference luminance difference range, Thereby adjusting the illuminance of the lighting apparatus.
반대로, 터널 내의 휘도가 터널 외부의 휘도보다 높을 경우에는 터널 내의 조명 기구의 휘도를 한단계씩 낮추는 역과정을 통해 휘도 편차를 기준 휘도차 범위 내로 유지시키도록 제어할 수 있다. On the contrary, when the luminance in the tunnel is higher than the luminance outside the tunnel, the luminance deviation can be controlled to be kept within the reference luminance difference range through the inverse process of lowering the luminance of the lighting device in the tunnel by one level.
상기와 같이 본 발명은 터널 진입과 터널을 벗어나는 시점에서 유발되는 시각적 방해 현상을 최소화할 수 있으므로 운전자가 안전하고 시각적으로 쾌적한 상태로 운전이 가능하다. As described above, since the visual disturbance caused at the time of entering the tunnel and leaving the tunnel can be minimized, the present invention can operate the driver safely and visually pleasantly.
이상에서 설명한 본 발명의 상세한 설명에서는 본 발명의 바람직한 실시예를 참조하여 설명하였지만, 본 발명의 보호범위는 상기 실시예에 한정되는 것이 아니며, 해당 기술분야의 통상의 지식을 갖는 자라면 본 발명의 사상 및 기술영역으로부터 벗어나지 않는 범위 내에서 본 발명을 다양하게 수정 및 변경시킬 수 있음을 이해할 수 있을 것이다.While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
