Description

프로젝트빔을 활용한 교차로 신호시스템{TRAFFIC LIGHTS SYSTEM FOR CROSSROADS}[0001] TRAFFIC LIGHTS SYSTEM FOR CROSSROADS [0002]

본 발명은 야간, 우천 및 안개 시 프로젝트빔을 이용한 교차로 신호시스템에 관한 것이다. The present invention relates to an intersection signaling system using project beams at night, rainy and fog.

차량(교통수단)은 인간이 탑승하여 선택된 출발 지점(위치)으로부터 선택된 도착 지점까지 지상(육상)을 따라 빠르고 편리하며 안전하게 이동하고자 하는 욕구를 충족시켜주는 매우 편리하고 유익한 발명품 중에 하나이며 현대와 향후의 인간생활에서 필요성이 더욱 높아질 장치(수단) 중에 하나이다.Vehicles are one of the most convenient and beneficial inventions that satisfy the desire to travel quickly, conveniently and safely along the ground (land) from the selected starting point (location) to the selected arrival point, Is one of the devices in which the necessity of human life becomes higher.

한편, 현대 사회는 산업 발달로 육상 이동용 차량의 수요가 급격히 증가하고 도로망 확충은 늘어나는 차량 숫자에 따라가지 못하거나 다수 차량이 일시에 밀집되는 지역에서는 차량혼잡으로 인한 경제적 손실이 막대하게 발생하는 등의 문제를 해결하는 것 중에 하나가 다양한 교통신호체계를 개발하는 것이며, 교통신호체계는 차량 흐름을 특정한 목적에 적합하게 이루어지도록 통제할 수 있다.On the other hand, in the modern society, the demand for land mobile vehicles has increased sharply due to the industrial development, and the road network expansion has failed to follow the increasing number of vehicles or the economic loss due to congestion has occurred One of the challenges is to develop a variety of traffic signaling systems, which can control the flow of traffic to a specific purpose.

즉, 차량은 매우 빠르게 이동할 수 있고 이동 중에 다른 물체와 충돌 등의 사고 발생시 귀중한 재산과 건강에 큰 피해를 끼칠 수 있다. 또한, 차량으로 물류를 이동시키는 경우 짧은 시간에 목적지까지 안전하고 정확하게 도착하는 것이 중요하므로 도로 정체에 의하여 교통 소통이 원활하지 못한 경우 경제적 손실이 발생하게 된다.In other words, the vehicle can move very quickly, and in the event of an accident such as a collision with another object on the move, it can cause great damage to valuable property and health. In addition, it is important to arrive at the destination safely and accurately in a short period of time when transporting the goods to the vehicle. Therefore, when the traffic is not smooth due to the traffic congestion, economic loss occurs.

그러므로 차량이 이동할 수 있는 전용 도로가 건설되고, 차량의 이동방향을 안전하게 전환할 수 있는 교차로가 설치되며 각 교차로에는 통행의 우선 순위(순서)를 지정(통제)하는 교통 신호등이 설치되어 운용되는 것은 매우 바람직하며 일반적이다.Therefore, there is an intersection where a private road can be constructed for the vehicle to move, and a direction in which the vehicle can move safely is installed. Traffic signals are assigned to each intersection to designate (control) traffic priorities Very desirable and common.

일반적으로 진행 방향이 다른 도로 또는 차선이 만나는 지점을 교차로라 하며 교차로에는 교통신호체계의 제어를 받은 교통신호등 또는 신호등이 설치 운용되고 있다.Generally, intersection is the intersection of road or lane with different direction of progress, and traffic signal lamp or traffic light controlled by traffic signal system is installed and operated at the intersection.

그런데 종래에는 도로의 차선의 구분이 모두 도료로 이루어져 있어 야간이나 특히 우중 및 안개가 심한 경우 차선 구분이 매우 어려운 문제점이 있다.However, conventionally, all of the lanes of the road are divided into paints, so that there is a problem that it is very difficult to distinguish the lane when nighttime, especially when there is heavy rain and fog.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and it is an object of the present invention to provide a liquid crystal display device, which is characterized in that all lanes are divided into paints, , DLP type, and LED beam to distinguish the vehicle by lane designated color and to utilize the effect of the traveling direction to help safe vehicle operation.

상기와 같은 목적을 달성하기 위한 본 발명의 프로젝트빔을 활용한 교차로 신호시스템은, 재생에너지를 이용한 LCD형,DLP형 및 LED 빔 등을 활용하여 차선 별 지정 색으로 구분하고 진행 방향에 대한 효과를 활용하여 안전한 차량 운행을 도울 수 있도록 차선에 대한 변경에 대한 것으로, 우천 및 안개 또는 사고 다발 교차로 구간에 도 1과 같이 파랑색 화살표에 표시된 교차로 신호등 기둥에 안개 감지센서나 광학센서를 설치하여 가시거리가 짧을 경우 센서가 그것을 인지하여 빨강색 화살표에 표시된 신호등 아래쪽에 고휘도 LED빔을 설치하여 교차로의 진입방향선을 표시 해주는 역할을 해준 것이다. 또한 교차로 뿐만 아니라 안개나 우천으로 인한 사고다발 구역에도 설치가 가능 하도록 할 수 있다.In order to achieve the above object, an intersection signal system using a project beam according to the present invention is divided into a designated color for each lane using an LCD type, a DLP type, and an LED beam using renewable energy, The fog detection sensor or the optical sensor is installed on the intersection traffic light column indicated by the blue arrow as shown in Fig. 1 in the rainy weather and fog or the traffic accident intersection section in order to help the safe driving of the vehicle. The sensor recognizes it and installs a high-intensity LED beam below the traffic light indicated by the red arrow to mark the entry direction line of the intersection. In addition, it can be installed at intersections as well as fog and rainy weather.

본 발명에 따르면, 차선의 구분이 모두 도료로 이루어져 있어 야간이나 특히 우중 및 안개가 심한 경우 차선 구분이 매우 어려운 점이 있어 재생에너지를 이용하여 LCD형, DLP형 및 LED 빔 등을 활용하여 차선 별 지정 색으로 구분하고 진행 방향에 대한 효과를 활용하여 차선의 시인성을 높여 안전한 차량 운행을 도울 수 있게 된다. According to the present invention, since all the lanes are divided into paint, it is very difficult to distinguish lanes in the nighttime, especially in the case of heavy rain and heavy mist. Therefore, by using renewable energy, By separating them into colors and using the effect on the direction of travel, it is possible to increase the visibility of the lane, thereby helping to safely operate the vehicle.
