상기 램프에는 전등갓이 상부에 설치되며, 상기 지주높이는 가로수의 높이보다 낮게 설치하여 가로수가 빛에 의한 스트레스가 적은 것이 본발명의 특징이다.The lamp has a lampshade installed on the top, and the height of the pillar is lower than the height of the street tree, so that the street tree has less stress due to light.
통상 가로수의 낮은 가지보다 일정거리 예를 들어 1m 정도 램프위치가 낮게 위치되게 한다.Usually, the lamp position is positioned lower than the lower branch of the street tree by a certain distance, for example, about 1m.
상기 지주는 상부지주와 하부지주로 구성되어 상부지주가 하부지주 내부에서 승하강한다. 가로등 높이는 3 내지 4m이고 승하강 조절거리는 통상 1.5m 정도이다.The post is composed of an upper post and a lower post, and the upper post moves up and down inside the lower post. The height of the streetlight is 3 to 4m, and the elevation control distance is usually about 1.5m.
상기 하부지주 내부는 고리가 설치되어 와이어가 연결되고 지면에는 정역모터가 설치되어 모터축이 하부지주 내부의 와이어와 연결되어 모터가 정역회전하면 와이어의 감김과 풀림에 의해 엘리베이터처럼 내부지주가 승하강하는 것이다.A loop is installed inside the lower pillar to connect the wire, and a forward and reverse motor is installed on the ground, and when the motor shaft is connected to the wire inside the lower pillar, and the motor rotates forward and backward, the inner pillar moves up and down like an elevator by winding and unwinding the wire. Is.
다른 실시례로서 상기 모터는 하부지주에 설치되고, 상부지주 내벽에는 래크가 상하로 설치되고, 상기 래크에는 피니언이 결합되어 모터가 피니언을 정역회전시키면 이와 결합된 래크가 승하강되며 상기 상부지주가 승하강되는 것이다.In another embodiment, the motor is installed on the lower post, the rack is installed up and down on the inner wall of the upper post, and a pinion is coupled to the rack, and when the motor rotates the pinion forward and backward, the combined rack is raised and lowered, and the upper post is It goes up and down.
다른 실시례로서 상기 상부지주와 하부지주 사이는 중간지주가 볼트너트에 의해 연결 설치되어 볼트너트를 풀어서 중간지주를 수동으로 신축시키고 다시 볼트를 결합함에 의하여 가로등의 길이가 조절되는 것이다.In another embodiment, between the upper and lower posts, an intermediate post is connected and installed by a bolt nut, and the intermediate post is manually stretched and contracted by loosening the bolt nut, and the length of the streetlight is adjusted by connecting the bolts again.
또는 상기 상부지주와 하부지주는 신축조인트에 의해 연결되어 신축조인트를 수동으로 신축시킴에 의하여 가로등의 길이가 조절되는 것이다.Alternatively, the upper post and the lower post are connected by an extension joint, and the length of the street lamp is adjusted by manually expanding and contracting the extension joint.
그리고 본발명은 상기 가로수의 잎이 무성한 봄여름에는 지주의 높이가 일정길이 상승하며, 적은 가을, 겨울에는 지주의 높이가 일정길이 하강하게 할 수 있다.And in the present invention, the height of the post is increased by a certain length in spring and summer when the leaves of the street trees are lush, and the height of the post can be lowered by a certain length in the less autumn and winter.
곧 제어부에는 타이머가 설치되어 봄여름에는 모터를 역회전하여 상부지주가 하강하게 하고, 가을, 겨울에는 모터를 정회전하여 상부지주가 상승하게 하는 것이다. 이때 타이머는 종래기술로서 매일 가로등램프가 점등하게 하는 시간을 설정할 수 있으므로 본발명의 기능을 타이머에 용이하게 추가할 수 있다.Soon, a timer is installed in the control unit so that the motor rotates reversely in spring and summer to make the upper column descend, and in the fall and winter, the motor rotates forward so that the upper column rises. At this time, since the timer is a conventional technology, it is possible to set a time for the street light lamp to light every day, so that the function of the present invention can be easily added to the timer.
다른 제어방법으로서 바람이 일정 풍속이상으로 불면 식물의 스트레스 지수가 높아지고 가지등이 휘어져 가로등에 부딛칠수 있으므로 풍속을 측정하는 풍속센서를 가로등 램프, 특히 램프갓 바로 아래에 설치하여 측정값을 전류 등으로 제어부에 전송하고 제어부는 설정값이상이면 모터를 역회전하여 상부지주가 하강하게 하는 것이다.As another control method, if the wind blows above a certain wind speed, the stress index of the plant increases and the branch lamps can be bent and hit the street light.Therefore, a wind speed sensor that measures the wind speed is installed under the street lamp, especially the lampshade, and the measured value is converted into current, etc. It is transmitted to the control unit, and the control unit rotates the motor reversely if it is above the set value and causes the upper column to descend.
그리고 본발명은 식물의 스트레스를 열화상카메라로 감지하여 스트레스가 설정치 이상일시 제어부에는 모터를 역회전하여 상부지주가 하강하게 하고, 스트레스가 정상수치이면 모터를 정회전하여 상부지주를 다시 상승하여 원래 높이로 위치시킨다. 열화상카메라를 이용해 식물의 스트레스를 판단하는 방법 자체는 공개특허공보 10-2018-0056010호 등에 널리 알려진 기술이므로 자세한 설명은 생략한다.In addition, the present invention detects the stress of the plant with a thermal imaging camera, and when the stress is above the set value, the control unit rotates the motor reversely to make the upper column descend, and when the stress is a normal value, the motor rotates forward to raise the upper column again to the original height. Position as A method of determining the stress of a plant using a thermal imaging camera itself is a technique widely known in Unexamined Patent Publication No. 10-2018-0056010 and a detailed description thereof will be omitted.
상기 식물의 스트레스를 감지하는 방법은 대표적인 가로수 하나를 선택하여 열화상카메라를 상부에 설치하고, 얻어진 영상에 나타나는 식물잎 온도를 기준설정온도와 대비하여 온도지수로 식물의 스트레스를 판단한다.In the method of detecting the stress of a plant, a thermal imaging camera is installed on the top by selecting one representative street tree, and the plant leaf temperature shown in the obtained image is compared with a reference set temperature to determine the plant stress by a temperature index.
온도지수가 1보다 많이 크면 식물이 양의 스트레스를 받고 있다고 판단, 1보다 많이 작아도 음의 스트레스를 받고 있다고 판단한다.If the temperature index is greater than 1, it is judged that the plant is under positive stress, and even if it is much less than 1, it is judged that it is under negative stress.
양의 스트레스를 받고 있다고 판단하면 가로등의 지주길이를 줄인다.If you determine that you are under positive stress, reduce the length of the streetlight's post.
특히 음의 스트레스를 받고 있다고 판단하면 조도를 크게 하고 상부지주를 상승하여 가온을 한다. 또는 설치된 히터를 작동한다.In particular, if you judge that you are under negative stress, increase the illuminance and increase the upper column to warm. Or operate the installed heater.
또는 가로수는 수분이 하절기, 동절기 등에 일정기간 적으면 스트레스를 받으므로 지중에는 수분센서를 설치하여 수분 측정값을 전류 등으로 제어부에 전송하고 제어부는 일정기간동안 설정값 이하이면 모터를 역회전하여 상부지주가 하강하게 한다.Or street trees are stressed when moisture is low for a certain period of time in summer or winter, so a moisture sensor is installed in the ground to transmit the moisture measurement value to the control unit, and if it is less than the set value for a certain period, the control unit rotates the motor reversely Let the props descend.
또한, 지주에는 관용의 미세먼지 감지센서가 설치되어 대기중 미세먼지가 기준치 이상이면, 야간에 전등조도를 높여서 주위를 더 밝게 하며, 대신 상부지주는 하강하여 가로수에게 스트레스를 주지 않게 한다. 곧 미세먼지 감지센서로부터 전송된 신호값이 설정값 이상이면 제어부는 전등 조도를 높이게 하여 주위를 더 밝게 하여 운전자나 보행자의 시야를 확보한다. 그리고 가로수가 밝은 빛에 스트레스를 받으므로 모터를 작동하게 하여 상부지주를 하강하게 한다.In addition, a conventional fine dust detection sensor is installed on the posts, so that if the fine dust in the air is above the standard value, the light illuminance is increased at night to make the surroundings brighter, and instead the upper posts descend to prevent stress on the street trees. Soon, if the signal value transmitted from the fine dust detection sensor is more than the set value, the control unit increases the illuminance of the light to make the surroundings brighter, thereby securing the driver or pedestrian's view. And since the street trees are stressed by the bright light, the motor is operated to lower the upper column.
이러한 제반 조치에도 식물스트레스가 줄지 않으면 벌레등 이유이므로 경보를 울리거나 관리자에게 전화를 한다.If the plant stress does not decrease even with all of these measures, the alarm is sounded or the manager is called because it is due to insects.
한편, 본발명의 가로등의 실시례로서, 도로중앙분리대에 설치되어 도로를 밝게 하는 양방향 가로등으로서, 상기 가로등은 램프부와, 상기 램프부가 고정되는 프레임으로 이루어진다.On the other hand, as an embodiment of the street light of the present invention, as a two-way street light installed on a road center divider to brighten a road, the street light includes a lamp unit and a frame to which the lamp unit is fixed.
상기 램프부는 중앙분리선의 좌측을 비추는 좌측램프(10)와 우측을 비추는 우측램프(20)로 이루어지며, 상기 프레임(30)은 수직봉으로서, 상기 좌우측램프(10, 20)는 대칭으로 프레임 좌우에 각각 좌우측 연결봉(41, 42)에 의해 설치된다.The lamp part is composed of a left lamp 10 that illuminates the left side of the center separation line and a right lamp 20 that illuminates the right side, and the frame 30 is a vertical bar, and the left and right lamps 10 and 20 are symmetrically arranged on the left and right sides of the frame. It is installed by left and right connecting rods 41 and 42, respectively.
상기 좌우측 램프 중앙에는 전기에 의해 작동되는 경광등(50)이 설치되어 운전자의 주의를 환기시킨다.A warning lamp 50 operated by electricity is installed in the center of the left and right lamps to draw attention of the driver.
그리고 상기 경광등은 널리 사용되는 것으로 주로 점멸식으로 설치된다.And the warning light is widely used and is mainly installed in a flashing type.
특히 본발명의 상기 좌우측 램프는 직사각형 형상으로서 평소에는 하방을 향하여 일정각도 기울어져서 운전자의 눈부심을 방지하는데 기술적 특징이 있다.In particular, the left and right lamps of the present invention have a rectangular shape and are generally inclined downward at a certain angle, thereby preventing the driver from glare.
그리고 본발명의 프레임 하단은 플랜지가 형성되고, 상기 플랜지에는 볼트구멍이 형성되어 볼트로 바닥에 체결가능한 것이다.In addition, a flange is formed at the bottom of the frame of the present invention, and a bolt hole is formed in the flange to be fastened to the floor with a bolt.
상대습도가 일정수치 이상이면, 2단계로서 조도를 높게 하며 경광등의 점멸주기를 짧게 하여 운전자의 주의를 환기한다. 상대습도가 더욱 크면 3단계로서 수평면에서의 경사각도를 크게 하여 넓은 범위를 비추는 것이고 본발명은 지주를 상부지주와 상기 상부지주가 삽입되는 하부지주로 구성되어, 길이가 신축되는 것으로, 상부지주에 결합된 모터를 가동하여 지주의 길이를 길게 하여 넓은 범위를 비추는 것이다.If the relative humidity is higher than a certain value, the illuminance is increased as a second step, and the flashing period of the warning light is shortened to call the driver's attention. If the relative humidity is higher, the inclination angle in the horizontal plane is increased in three stages to illuminate a wide range.The present invention consists of an upper post and a lower post into which the upper post is inserted, and the length is extended and contracted to the upper post. It is to illuminate a wide range by increasing the length of the post by operating the motor.
또한, 차량이 부딪치려하면 경고음을 울리고 차량이 부딛쳐 일정충격량을 넘어서면 에어백을 방출하는 것이다.In addition, a warning sound is sounded when a vehicle is about to hit, and an airbag is released when the vehicle hits and exceeds a certain amount of impact.
상기 에어백이 충격에 의해 자동방출되는 구성은 종래 관용기술을 적용하는 것이므로 자세한 설명은 생략한다.The configuration in which the airbag is automatically released by impact is to apply a conventional technique, and thus a detailed description thereof will be omitted.
본발명은 가로등의 제어부는 일정시간 동안 통과하는 차량의 대수에 비례하여 램프의 조도를 높게 하거나 낮게 조절하는 것이다. 가로등에는 관용의 속도센서, 무선자력계, 무선초음파센서, 적외선센서, 또는 cctv 카메라등의 관용의 차량감지센서가 설치되어 있어서, 일정시간 동안 도로를 통과하는 차량수를 제어부에서 계산할 수 있다. In the present invention, the control unit of the street lamp adjusts the illuminance of the lamp to be increased or decreased in proportion to the number of vehicles passing for a certain period of time. A conventional vehicle detection sensor such as a conventional speed sensor, a wireless magnetometer, a wireless ultrasonic sensor, an infrared sensor, or a cctv camera is installed in the street light, so the number of vehicles passing through the road for a certain period of time can be calculated by the control unit.
그러므로 설정치 이상의 차량이 일정시간내 통과하면 조도를 높게 하고 설정치보다 미만의 차량이 일정시간내 통과하면 센세가 이를 감지하여 제어부에 전송하면 제어부는 램프의 조도를 낮게 하여 에너지를 줄인다. 곧 차량평균대수가 1은 정상상태, 1미만은 가령 0.9, 0.8 등은 차량통행이 적은 상태이므로 조도를 낮추고, 1보다 높으면, 가령 1.1, 1.2의 경우에는 차량이 많은 상태이므로 조도를 높인다.Therefore, when a vehicle above the set value passes within a certain period of time, the illuminance is increased, and when a vehicle less than the set value passes within a certain period of time, the sensor detects it and transmits it to the controller, the controller decreases the illuminance of the lamp to reduce energy. In other words, when the average number of vehicles is 1 in the normal state, for example, 0.9 and 0.8 for less than 1, the illuminance is lowered because the vehicle traffic is low, and if it is higher than 1, for example, 1.1 and 1.2, the illuminance is increased because there are many vehicles.
그리고 가로등에는 속도센서에 의해 차량의 통과속도를 감지하며, 일정시간내 통과하는 차량들의 평균속도가 설정치 이상이면 조도를 높게 하고 설정치보다 미만이면 조도를 낮게 하여 에너지를 줄인다. 곧 차량평균통과속도가 1은 정상상태, 1미만은 가령 0.8, 0.6 등은 속도가 낮으므로 조도를 낮추고, 1보다 높으면, 가령 1.2, 1.4의 경우에는 차량속도가 빠른 경우이므로 사고의 우려가 높아지므로 조도를 높인다. In addition, the speed sensor detects the passing speed of the vehicle on the streetlight, and if the average speed of the vehicles passing within a certain period of time is higher than the set value, the illuminance is increased, and if it is less than the set value, the illuminance is lowered to reduce energy. In other words, if the average vehicle passing speed is 1 in the normal state, for less than 1, for example 0.8, 0.6, etc., the illuminance is lowered, and if it is higher than 1, for example, 1.2, 1.4, the vehicle speed is high, so there is a high risk of an accident. It increases the illuminance.
상기 일정시간내 통과되는 차량대수비율지수와 평균속도비율지수는 별개로 제어하여 조도를 변경하여 적정조도를 구할수 있고, 또는 차량대수비율지수와 차량들의 평균속도비율지수를 기본조도에 함께 곱하여 적정조도를 구할 수 있다. 예로서 차량대수가 평균보다 적어서 차량대수비율지수가 0.8이고 차량속도가 평균보다 느려서 속도비율지수가 0.7이면 가로등의 조도는 기본조도 1에 0.8과 0.7을 곱한 값이 가로등의 변경조도가 된다.The vehicle-to-vehicle ratio index and the average speed ratio index can be controlled separately to obtain an appropriate illuminance by changing the illuminance, or by multiplying the vehicle-to-car ratio index and the average speed ratio index of vehicles together with the basic illuminance. You can get the illuminance. For example, if the number of vehicles is less than the average and the vehicle-to-vehicle ratio index is 0.8, and the vehicle speed is slower than the average and the speed ratio index is 0.7, then the basic illuminance 1 multiplied by 0.8 and 0.7 is the change illuminance of the streetlight.
따라서 본발명은 가로수 곁에 설치되는 가로수 친화형 가로등의 램프 설치위치를 가로수 높이 이하에 설치하여 가로수에 빛에 의한 스트레스를 줄이고 차량통과 대수에 비례하여 조도를 제어하며 가로등의 지주는 높이조절이 가능하여 환경여건에 따라 자동으로 지주의 높이를 조절하여 가로수와 조화롭게 설치되는 현저한 효과가 있다.Therefore, the present invention reduces the stress caused by light on the street trees by installing the lamp installation position of the street tree-friendly streetlight installed next to the street tree, and controls the illumination in proportion to the number of vehicles passing, and the height of the street lamp is adjustable. There is a remarkable effect of being installed in harmony with the street trees by automatically adjusting the height of the post according to the environmental conditions.
