역광시 교통 신호 지시기를 쉽게 판단할 수 있는 보조 교통 신호 지시체계 장치 제작 및 그 운전 방법{Manufacture of assistance traffic signal indication system and its operation method for convenient judgement of traffic signal indicator at backlight}Manufacture of assistance traffic signal indication system and its operation method for convenient judgement of traffic signal indicator at backlight}

본 발명은 교통 신호 지시기의 식별을 용이하게 하기 위한 것으로, 차량을 운전할 경우 역광에 의해 교통 신호 지시기를 식별하지 못한 사고의 위험이 있으므로 역광에 의한 빛 반사로 교통 신호 지시등에 장착된 센서에 의해 작동되며, 그에 따라 교통 신호 지시등에 부착된 표지판을 돌출시켜 교통신호를 식별을 용이하게 하는 방법에 관한 것이다.The present invention is intended to facilitate the identification of the traffic signal indicator, the operation of the vehicle is driven by the sensor mounted on the traffic signal indicator light reflection of the light reflected by the backlight because there is a risk of accidents that do not identify the traffic signal indicator by backlight The present invention relates to a method for easily identifying a traffic signal by protruding a sign attached to the traffic signal indicator.

현재 사용되고 있는 교통 신호 지시기는 적색, 황색, 녹색으로 구분되어 있으므로 태양 빛의 역광에 의해 생기는 빛 반사로 인해 교통 신호 지시기의 색을 구별하기가 쉽지 않아서 역광에 의해 교통 신호 지시기가 반사되어 교통 신호 지시기의 색의 구별이 어려워져 사고의 위험이 있는 경우가 종종 있다. 이러한 경우 교통 신호 지시기의 색을 잘못 판단하고 교차로를 지날 경우 다른편에서 오는 차와 사고가 나기 쉽다는 문제점이 있다.Currently used traffic signal indicators are divided into red, yellow, and green, so it is not easy to distinguish the color of the traffic signal indicator due to the light reflection caused by the backlight of the sun. There is often a risk of accidents due to difficulty in distinguishing colors. In this case, if the color of the traffic signal indicator is incorrectly judged and crosses an intersection, there is a problem that cars and accidents from the other side are likely to occur.

교통 신호 지시기의 식별을 용이하게 위한 방법으로 교통 신호 지시기에 검정색의 원통형 차광갓을 설치하여 역광을 차단하는 방법을 적용하여 사용하고 있으나 빛의 각도가 시간에 따라 바뀌므로 모든 각도를 차광갓을 이용하여 차단할 수가 없고 특히 태양 빛이 역광으로 비추면 고통 신호 지시기를 식별하기 어려운 문제점을 갖고 있다. 또한 역광을 차단하는 방법으로 교통 신호 지시등에 스티카 형식으로 직접 부착하여 사용하는 방법이 있는데 이러한 방법을 사용할 경우는 역광을 차단시킬 수 있지만 교통 신호 지시등의 빛을 약화시킬수 있기 때문에 밤에는 교통 신호 지시등이 식별이 어렵다는 문제점이 있다.In order to facilitate the identification of the traffic signal indicator, a black cylindrical shading shade is installed on the traffic signal indicator to block the backlight, but since the angle of light changes with time, it is necessary to block all angles using the shading shade. The problem is that it is difficult to discern pain signal indicators, especially when sunlight is backlit. In addition, there is a method to directly block the traffic signal indicators in the form of a sticker, which can block the backlight, but it may weaken the light of the traffic signal indicators at night. There is a problem that it is difficult to identify.

또한 색맹 및 색약자를 위한 식별로 교통 신호 지시기의 외부유리에 직사각형 도형, 삼각형 도형 등을 채색하여 교통 신호 지시기를 구분하여 사용하는 방법이 있고, 또는 특정한 표시를 외부유리에 부착시켜 사용하는 방법이 있다.In addition, there is a method of distinguishing a traffic signal indicator by using a rectangular or triangular figure on the outer glass of the traffic signal indicator for identification of color blindness and color weakness, or by attaching a specific mark to the outer glass. .

상기와 같은 문제점을 해결하기 위한 본 발명의 목적은 교통 신호 지시기에 역광에 의한 빛의 강도나 각도에 따라 반응할 수 있는 광 센서를 장착하여 보조 교통 신호 지시체계의 후면에 부착된 표지판을 작동시켜 교통 사고 위험을 사전에 차다하고, 색맹 또는 색약자들이 교통 신호등을 쉽게 구분할 수 있는데 있다.An object of the present invention for solving the above problems is to equip the traffic signal indicator with a light sensor that can react according to the intensity or angle of light caused by backlighting to operate the sign attached to the back of the auxiliary traffic signal indicator system The risk of accidents in advance, color blind or color weak people can easily distinguish traffic lights.

본 발명은 교통 신호 지시기의 적색, 녹색등 하부에 운전자가 식별하기 용이한 표지판을 부착하는 방법과 차광갓에 장착된 광 센서를 이용하여 빛의 강도나 각도에 따라 보조 교통 신호 지시체계에 부착된 표지판을 작동시키고, 또한 교통신호기의 적색, 황색, 녹색등 대신에 기존의 전구보다 식별이 용이한 광원인 발광다이오드로 대체함으로서 달성된다.The present invention is a sign attached to the auxiliary traffic signal indicator system according to the intensity or angle of light by using a light sensor mounted on the shading shade and a method for attaching a sign that is easy for the driver to identify under the red and green lights of the traffic signal indicator. And by replacing the red, yellow, and green lights of the traffic signal with light emitting diodes, which are easier to identify than conventional bulbs.

차량운전자가 교통 신호 지시기를 식별하지 못해 발생하는 사고의 위험을 감소시키기 위한 것으로 본 발명의 실시예인 구성과 그 작용을 첨부도면에 연계시켜상세히 설명하면 다음과 같다.In order to reduce the risk of an accident caused by a vehicle driver not identifying a traffic signal indicator, the configuration and the operation of the embodiment of the present invention will be described in detail with reference to the accompanying drawings.

본 발명의 구성은 교통 신호 지시기(1)에 있어서 적색등(2) 후면에 부착된 적색표지판(3)과 녹색등(4) 후면에 부착된 녹색표지판(5)으로 되어 있고, 이러한 적색표지판(3)과 녹색표지판(5)이 상하로 움직일 수 있도록 작동시키는 stepping motor(6)가 있으며, stepping motor(6)를 컨트롤하기 위한 컨트롤 박스(7), 빛의 입사각을 조절하는 차광갓(8), 빛의 입사강도를 측정하는 광 센서(9) 구성되어 있다. 도 1과 2는 교통 신호 지시기의 정면도와 후면도를 나타낸 것이다. 교통 신호 지시기(1)는 적색등(2), 황색등, 녹색등(4)으로 구성되어 있으며 교통 신호 지시기(1)의 상부에는 빛의 입사각도를 조절할 수 있는 차광갓(8)과 차광갓을 통과하는 빛의 강도를 측정할 수 있는 광 센서(9)가 2 개 장착되어 있다. 여기서 빛의 강도를 측정할 수 있는 광 센서(9)로는 일반적으로 이용되는 solar cell을 사용하며, 이러한 광 센서(9)를 이용하여 태양 빛의 강도가 역광이 되는 위치에 있고, 빛의 강도가 일정한 크기 이상이 되는 세기로 측정되면 그 신호는 컨트롤 박스(7)로 보내지며, 컨트롤 박스(7)에 의해 stepping motor(6)를 작동하게하여 적색 표지판(3)과 녹색 표지판(5)이 교통 신호 지시기(1)이 작동할 때 동시에 작동하게 된다. 예를 들어 적색등(2)이 켜졌을 때 stepping motor(6)를 작동시켜 적색표지판(3)이 교통 신호기 하부로 돌출 시킨다. 또한 녹색등(4) 켜졌을 경우에도 상기와 같은 원리로 작동하게 된다. 역광시에 돌출되는 적색 표지판(3)과 녹색 표지판(5)은 역광에 영향을 받지 않아야 하며, 육안으로 쉽게 판단 될수 있는 물질을 사용하여 제작하기 위한 백색 안료에 원형의 적색과 녹색으로 구성되어 있다.The construction of the present invention comprises a red sign (3) attached to the rear of the red light (2) and a green sign (5) attached to the rear of the green light (4) in the traffic signal indicator (1). 3) and a stepping motor (6) for operating the green sign (5) to move up and down, a control box (7) for controlling the stepping motor (6), a shading shade (8) for adjusting the incident angle of light, The optical sensor 9 which measures the incident intensity of light is comprised. 1 and 2 show a front view and a rear view of a traffic signal indicator. The traffic signal indicator 1 is composed of a red light (2), a yellow light, a green light (4), and the upper part of the traffic signal indicator (1) passes through a shading shade (8) and a shading shade for adjusting the incident angle of light. Two optical sensors 9 are provided for measuring the intensity of light. Here, a solar cell generally used is used as an optical sensor 9 capable of measuring the intensity of light, and by using such an optical sensor 9, the position of solar light is backlit, and the intensity of light is When measured at an intensity greater than a certain magnitude, the signal is sent to the control box (7), which causes the red sign (3) and the green sign (5) to communicate by driving the stepping motor (6) by the control box (7). When the signal indicator 1 is activated, it operates simultaneously. For example, when the red light (2) is turned on, the stepping motor (6) is operated so that the red sign (3) protrudes below the traffic signal. In addition, when the green light (4) is turned on will operate on the same principle as above. Red signs (3) and green signs (5) protruding in backlighting should not be affected by backlight, and are composed of circular red and green in white pigment for production using materials that can be easily judged by the naked eye. .

도 3과 4는 교통 신호 지시등(1)의 작동원리와 전면도를 나타내었다. 교통 신호 지시기(1)의 상부에 위치한 광 센서(9)는 태양 빛의 입사각도를 조절할 수 있는 차광갓(8)에 위치하고 있다. 역광에 의해 교통 신호 지시기(1)이 영향을 받아 식별이 되지 않는 각도를 차광갓(8)을 이용하여 각도를 조절하고, 입사강도를 측정하는 광 센서(9) 2 개로 구성되어 있으며 1번 광 센서(9)의 입사강도와 2번 센서(9)의 입사강도는 독립적으로 작동되며, 각각의 광센서(9)에서 일정수준의 세기가 측정되면 이러한 시스템은 작동하게되며, 차광갓(8)에 의해 빛이 광 센서로 입사하지 못하면 이 시스템은 작동하지 않으며 또한 흐린날이나 빛이 없는 밤에는 빛의 강도 세기가 떨어지기 때문에 본 보조 교통 신호체계는 작동되지 않게 하였다.3 and 4 show the operating principle and the front view of the traffic signal indicator (1). The light sensor 9 located above the traffic signal indicator 1 is located in the shading shade 8, which can adjust the incident angle of the sun light. The traffic signal indicator 1 is affected by the backlight, and the light shield shade 8 is used to adjust the angle and to measure the incident intensity. The incident intensity of (9) and the incident intensity of the second sensor (9) operate independently, and when a certain level of intensity is measured in each of the optical sensors (9), the system is activated, and by the shading shade (8) The system does not work if light does not enter the light sensor, and the secondary traffic signal system is disabled because the intensity of light decreases during overcast or no-light nights.

또한 교통 신호 지시기(1)의 식별을 원활히 하기 위하여 적색등(2), 황색등, 녹색등(4)을 기존에 사용하고 있는 광원이 아닌 가격이 저렴한 LED를 대체하는 것도 가능하다.In addition, in order to facilitate identification of the traffic signal indicator 1, it is possible to replace the low-cost LED than the light source that uses the red light (2), yellow light, green light (4).

상기와 같은 본 발명은 역광시 차량을 운전할 경우 운전자가 빛 반사에 의해 교통 신호 지시등을 식별하지 못해 발생하는 사고로부터 위험을 방지하기 위한 것이다. 교통 신호 지시등은 육안으로 식별이 용이하게 하였으며, 역광시에 빛을 흡수할 수 있는 물질을 사용하여 빛 반사에 의해 보이지 않는 것을 방지할 수 있다.The present invention as described above is to prevent a danger from an accident caused when the driver does not identify the traffic signal indicator by the light reflection when driving the vehicle in backlight. Traffic signal indicators are easy to identify with the naked eye, and can be prevented from being reflected by light reflection by using a material that can absorb light in the backlight.
