Abstract

PURPOSE: A traffic signal system capable of controlling and detecting a traffic signal status using power line communication is provided to improve maintenance and management operation by transmitting and receiving a signal using a power line without a dedicated communication line. CONSTITUTION: An LED(Light Emitting Device) module(130) serves as a light source of a traffic signal. A power supply(110) converts AC(Alternating Current) power applied from a traffic signal controller(220) through a power line into DC(Direct Current) power suitable for driving the LED module. A LED module(130) controls luminosity of the LED module by adjusting a DC voltage (or DC current) provided from the power supply. An LED failure detecting unit(140) detects a voltage and/or current of each LED of the LED module to determine the failure of each LED. A power line communication unit(160) communicates with the traffic signal controller using the power line. A data controller(150) calculates a failure rate based on information related to the determination result and forms data in a frame unit to send it to the power line communication unit.

Description

전력선통신을 이용한 신호등의 상태 및 제어가 가능한 교통신호등 시스템{A traffic signal system for state and control of traffic signal using power line communication}A traffic signal system for state and control of traffic signal using power line communication

본 발명은 발광다이오드(Light Emitted Diode: LED)를 광원으로 하는 신호등에 관한 것으로서, 보다 상세하게는 LED 소자의 고장을 검출하고 그에 따른 광도 조절 기능을 구비한 제어부가 신호등에 구비되고, 신호등제어기와의 통신을 전력선을 이용하여 수행하는 전력선통신을 이용한 신호등의 상태검출 및 제어가 가능한 LED 신호등에 관한 것이다.The present invention relates to a signal lamp using a light emitting diode (LED) as a light source, and more particularly, a signal lamp includes a control unit for detecting a failure of an LED element and having a brightness control function according to the signal lamp. The present invention relates to an LED signal lamp capable of detecting and controlling a state of a signal lamp using power line communication for performing communication using a power line.

일반적인 교통신호 시스템은 도 1에 도시된 바와 같이 하나의 4거리에 신호등 제어기(2)가 하나 설치되고 각 방향으로 1개 또는 다수의 차량용 신호등이 설치되어 있다. 보행자용 신호등은 도면에서 제외하였다. 기술의 발달에 따라 신호등이 백열등(白熱燈)에서 발광 다이오드(Light Emitted Diode) 신호등으로 교체되고 있는 추세이다.In the general traffic signal system, as shown in FIG. 1, one traffic light controller 2 is installed at one distance and one or more vehicle traffic lights are installed in each direction. Pedestrian traffic lights are excluded from the drawings. With the development of technology, traffic lights are being replaced with incandescent light bulbs.

LED 신호등은 광원을 LED 소자를 사용하여 기존의 백열전구 이용시 보다 전력소모가 약 85%~90%이상 절약 할 수 있으며, 폭우나 폭설 혹은 안개 낀 날에 시인성이 우수하고, 태양반사에 의한 팬텀현상(Sun Phantom)이 없어 교통사고를 감소시킬 수 있는 장점을 가지고 있다. 따라서 세계 여러 국가에서 이러한 장점 때문에 오래 전부터 LED 신호등으로 교체하고 있으며, 우리 나라도 시행 중에 있다.LED signal light can save about 85% ~ 90% more power than conventional incandescent lamps by using LED element as a light source, and it is excellent in visibility in heavy rain, heavy snow or fog, and phantom phenomenon caused by solar reflection. There is no (Sun Phantom), which has the advantage of reducing traffic accidents. Therefore, many countries in the world have been replacing LED signals for a long time because of these advantages, and our country is also in operation.

종래 기술에 따른 LED 교통 신호등 시스템의 전체구성은 도 2에 도시된 바와 같다. 종래의 LED 신호등(10)은 단순히 교통신호등제어기(20)에서 공급되는 교류전력을 전원공급기(11)를 통해 직류전력으로 변환시켜 LED 모듈(12)을 구동하도록 되어있다.The overall configuration of the LED traffic light system according to the prior art is as shown in FIG. The conventional LED traffic light 10 is configured to drive the LED module 12 by simply converting the AC power supplied from the traffic light controller 20 into DC power through the power supply 11.

하지만, LED 신호등의 단점으로는 백열전구와 달리 LED 소자에서 방출되는 광은 단일파장으로 규정이상으로 과도하게 광도를 밝게 했을 경우, 장시간 LED 신호등을 보게되면 눈의 피로 및 눈앞이 순간적으로 어둡게 보이는 현상이 발생한다. 이러한 현상은 주간보다 야간에 더 심하게 나타난다.However, the disadvantage of LED traffic light is that, unlike incandescent bulbs, when the light emitted from an LED device is excessively bright due to a single wavelength, the eye fatigue and eyes appear momentarily dark when looking at the LED signal for a long time. Occurs. This is more severe at night than during the day.

또 다른 단점으로는 LED 신호등은 백열전구식 신호등과 달리 단일광원이 아니라 수백 개의 LED 소자로 구성되어있다. 따라서 LED 소자 중 일부가 고장이 발생해도 나머지는 동작되어 빛을 발생한다. 따라서 신호등의 외관은 불규칙하게 빛이 발생되며 특히, 차량 녹색등인 경우 방향등의 화살표와 혼동을 일으켜 교통사고와 직결될 수 있다. 다시 말해, 직진 신호등의 일부 LED가 고장으로 공교롭게 화살표 비슷한 형상으로 불이 들어온 경우, 좌회전 또는 우회전 등 방향 지시등(指示燈)과의 혼동을 유발할 수 있는 소지가 있는 것이다.Another disadvantage is that LED traffic lights, unlike incandescent bulbs, consist of hundreds of LED elements rather than a single light source. Therefore, if some of the LED elements fail, the others operate to generate light. Therefore, the appearance of the traffic light is irregularly generated, in particular, in the case of the vehicle green light can be directly connected to the traffic accident by causing confusion with the arrow of the direction light. In other words, if some LEDs of the straight traffic light light up in an arrow-like shape due to a failure, there is a possibility that it may cause confusion with a turn signal such as a left turn or a right turn.

따라서 LED소자가 고장이 발생하더라도 신속히 발견하여 처리하기가 힘들고 광도 또한 주간과 야간이 동일하여 상대적으로 야간에 밝은 빛으로 인해 눈에 피로가 더할 수 있다.Therefore, even if the LED device breaks down, it is difficult to detect and process it quickly, and the brightness is also the same as day and night, which may cause eye fatigue due to the bright light at night.

본 발명은 별도의 제어선을 사용하지 않고 신호등(信號燈)의 상태 및 제어를 수행할 수 있는 교통신호등 시스템을 제공하는 것을 목적으로 한다.An object of the present invention is to provide a traffic light system capable of performing the state and control of a traffic light without using a separate control line.

As shown, the traffic light controller 200 is provided with a power line communication unit 210 and the traffic light control unit 220, each LED traffic light 100, is formed in a predetermined form arranged in a traffic signal (Traffic Signal) LED module 130 used as a light source of (); A power supply unit 110 that receives the AC power supplied from the traffic light controller 200 through the power line and converts the DC power into DC power so as to drive the LED module 130; A brightness control unit 120 for controlling the brightness of the LED module by adjusting a DC voltage (or current) provided through the power supply unit 110; LED failure detection unit 140 for sensing the failure of the LED element by sensing the voltage and / or current according to each LED array of the LED module and outputs the result; A power line communication unit 160 for performing data communication with a traffic light controller using an AC power line for a traffic signal without a separate communication line; After calculating the failure rate (故障 率) according to the value provided from the fault detection unit 140 to configure the data in units of frames, through the power line communication unit 160 to provide to the traffic light controller 200, the traffic light controller 200 It provides a brightness control function of the LED module through the brightness control unit by reading the brightness control data provided from the), and includes a data control unit 150 for controlling the transmission of other control signals and monitoring signals related to the traffic light controller and traffic lights It is configured by.

본 발명에서는 LED 신호등의 동작에 필요한 교류전력을 제공하는 전력선을 이용하여 데이터의 교환을 수행하는 전력선 통신방법을 사용한다.신호등제어부(220)에서는 주간과 야간에 따른 광도 조절 신호를 송출한다. 이 신호는 신호등제어기(200)내의 전력선통신부(210)로부터 전력선을 통해 각 LED 신호등내의 각 전력선통신부(160)에 전달된다. 다시 데이터제어부(150)를 거쳐 해독되어 광도조절부(120)의 제어값으로 변환하여 LED 모듈(130)의 동작을 제어한다.In the present invention, a power line communication method for exchanging data using a power line providing AC power required for operation of an LED signal lamp is used. The signal lamp control unit 220 transmits a brightness control signal for day and night. This signal is transmitted from the power line communication unit 210 in the traffic light controller 200 to each power line communication unit 160 in each LED traffic light via a power line. The data is again decoded through the data controller 150 and converted into a control value of the light intensity controller 120 to control the operation of the LED module 130.

LED 모듈(130)은 광원(光源)으로서 다수의 LED 소자로 구성되어 있으며, LED 배열은 직렬구조, 매트릭스(matrix)구조 및 직렬/매트릭스 혼합구조 등 다양한 방법으로 구성할 수 있다.The LED module 130 is composed of a plurality of LED elements as a light source, and the LED array may be configured in various ways such as a series structure, a matrix structure, and a series / matrix mixed structure.
