도 1은 본 발명에 따른 신호등 자동 제어 시스템을 나타내는 블록도이다.1 is a block diagram showing a traffic light automatic control system according to the present invention.

본 발명에 따른 신호등 자동 제어 시스템은 교차로의 신호등상에 설치되어 교차로의 진향방향별 대기차선에서 정지선으로부터 교차로 밖으로 소정거리이내에 차량의 존재유무를 판별하여 그에 해당하는 신호를 출력하는 센서(10)와, 입력되는 동작제어신호에 의하여 점멸이 제어되어 차량의 진행을 제어하는 신호등(20)과, 상기 센서(10)로부터 출력되는 신호를 기준으로 하여 각 대기차선 모두에 차량이 있을 경우에는 신호등(20)을 정상동작시키고 진행순서가되는 대기차선에 차량이 없을 경우에는 차량이 있는 다음 대기차선의 신호등(20)을 푸른색등으로 점등시켜 차량이 원활히 진행할 수 있도록 하는 제어부(30)로 구성된다.Traffic light automatic control system according to the present invention is installed on the traffic light of the intersection and the sensor 10 for determining the presence of the vehicle within a predetermined distance out of the intersection from the stop line in the waiting lane for each direction of the intersection and outputs a corresponding signal; The flashing is controlled by the input operation control signal to control the progress of the vehicle, and when there are vehicles in each of the waiting lanes based on the signal output from the sensor 10, the traffic light 20 If there is no vehicle in the waiting lane to operate normally and proceeds, the control unit 30 enables the vehicle to proceed smoothly by lighting the traffic light 20 of the next waiting lane in which the vehicle is turned to a blue light.

상기한 바와 같이 구성된 본 발명의 구성에서 제어부(30)의 동작을 하기에서 첨부된 도 2를 참조하여 살펴본다.The operation of the control unit 30 in the configuration of the present invention configured as described above will be described with reference to FIG. 2.

도 2는 본 발명에 따른 신호등의 동작순서를 나타내는 순서도이다.2 is a flowchart showing an operation procedure of a traffic light according to the present invention.

우선, 제어부는 신호등을 정상동작시키면서(S101), 신호등의 점등상태가 녹색등에서 황색등으로 변환되는지를 판단하여(S102), 황색등으로 점멸될 경우 다음 녹색등 점등을 대기하고 있는 대기차선에 차량이 있는지를 판단한다.(S103)First, the controller determines whether the lighting state of the traffic light is changed from green light to yellow light (S102) while operating the traffic light normally (S101), and when the yellow light flashes, the vehicle is waiting for the next green light to be waited on. It is determined whether there is any (S103).

상기한 판단과정(S103)에서 다음 대기차선에 차량이 있을 경우에는 제어부는 상기스텝 S101로 귀환하여 신호등을 정상동작 시키고, 상기 판단과정(S103)에서 다음 대기차선에 차량이 없다고 판단되면, 제어부는 녹색등이 점등되는 순서대로 각 대기차선에 차량이 있는지를 판단(104)하여, 차량이 있는 가장 빠른 순서의 대기차선의 신호등을 녹색등신호등으로 점등시킨다(S105).If there is a vehicle in the next waiting lane in the determination process (S103), the control unit returns to the step S101 to operate the traffic light normally, and if it is determined that there is no vehicle in the next waiting lane in the determination process (S103), the control unit It is determined whether there is a vehicle in each waiting lane in the order that the green light is turned on (104), and the traffic light of the waiting lane in the fastest order in which the vehicle is lit is lit by the green light signal (S105).

이와 같은 비정규적인 녹색등 점등과정(S105)에서 제어부는 다른 대기차선에 차량이 있는지를 판단(S106)하여, 다른 대기차선에 차량이 없을 경우에는 계속해서 점등중인 녹색등을 점등(S105)시키고, 다른 대기차선에 차량이 있을 경우에는 일정시간(교차로 진입차량이 교차로를 통과할 수 있도록 하는 시간 혹은 정규적인 녹색등 점등시간)을 경과후 대기차량이 있는 다음 대기차선의 진행방향신호등을 녹색등으로 점등한(S107)후, 스텝 S101로 귀환한다.In this irregular green light lighting process (S105), the controller determines whether there is a vehicle in another waiting lane (S106), and when there is no vehicle in another waiting lane, the controller continuously turns on the green light that is being turned on (S105), If there is a vehicle in another waiting lane, after a certain period of time (such as the time at which the intersection vehicle passes through the intersection or the regular green light turn-on time), the traffic light of the next waiting lane with the waiting vehicle turns green. After lighting (S107), the flow returns to step S101.

이와 같이 구성된 본 발명의 실시 예를 도 3의 삼거리를 예로 들어 하기에서 살펴본다.An embodiment of the present invention configured as described above will be described below with reference to the three-way distance of FIG. 3.

우선, 현재 1번 차선의 차량이 진행중 즉 1a신호등이 녹색등으로 점등되고, 2번과 3번 차선에는 다음 직진신호 즉 신호등 2a, 3a의 녹색등 점등을 기다리는 차량이 대기중이라고 가정한다.First, it is assumed that a vehicle in lane 1 is currently in progress, i.e., the traffic light 1a is turned on with a green light, and in lanes 2 and 3, there is a vehicle waiting for the next straight signal, that is, the green lights of the traffic lights 2a and 3a.

이와 같이 1번차선의 차량이 진행중일 경우 제어부는 센서로부터 출력되는 신호를 기준으로 하여 2번차선과 3번차선에 차량이 대기중인지를 판단하게 되는데 도 2에 나타내는 바와 같이 2번차선과 3번차선에 차량이 대기중이므로 제어부는 신호등을 정상동작 즉, 1a신호등을 정상적인 동작시간과 주기로 녹색등에서 황색등 그리고 적색등순으로 점등시키면서, 2a,3a신호등을 녹색등으로 동시에 점등시켜 차량이 진행할 수 있도록 한다.As described above, when the vehicle in lane 1 is in progress, the controller determines whether the vehicle is waiting in lanes 2 and 3 based on the signal output from the sensor, as shown in FIG. 2. As the vehicle is waiting in the lane, the controller lights the traffic lights in normal operation, that is, the 1a traffic lights in the order of normal operation time and cycle from green light to yellow light and then red light. do.

이와 같이 2번과 3번차선의 차들이 진행되는 과정에서 제어부는 센서로부터 출력되는 신호를 기준으로 하여 1번 차선에 대기중인 차량이 있는지를 판단하는데 도 2와 같이 1번차선에 대기차량이 없을 경우에는 2a및 3a신호등의 녹색등 점등을 유지하고, 1번차선에 대기중인 차량이 있을 경우에는 교차로에 진입한 차량이 교차로를 빠져나가도록 하는 시간 혹은 녹색등의 점등 시간이 매우 짧을 경우에는 기본적인 녹색등 점등시간을 경과한 후, 황색등과 적색등 순서로 2a및 3a신호등을 점등시키면서 1a신호등을 녹색등으로 점등시킨다.As described above, the controller determines whether there is a vehicle waiting in lane 1 on the basis of the signal output from the sensor. As shown in FIG. In this case, the green lights of 2a and 3a signals are kept on. If there is a vehicle waiting in lane 1, the time required for the vehicle entering the intersection to exit the intersection or the lighting time of the green light is very short. After the green light turn-on time has elapsed, the 1a light is turned on by the green light while the 2a and 3a lights are turned on in the order of the yellow light and the red light.

이에 따라, 차량이 교차로에서 불필요한 대기를 할 필요가 없어짐과 아울러 불필요한 대기시간으로 인한 교통혼잡을 방지할 수 있게 되는 것이다.As a result, the vehicle does not need to wait at the intersection and can prevent traffic congestion due to unnecessary waiting time.

따라서, 본 발명에 의하면 녹색등 점등순서가 된 임의의 대기차선에 차량이 없는 경우 진입대기차량이 있는 다른 차선의 진행신호등이 점등되도록 함으로써, 교차로에서 차량의 불필요한 차량의 대기가 없도록 하여 교차로 신호 대기로 인한 교통혼잡을 방지하는 효과가 있다.Therefore, according to the present invention, when there is no vehicle in any waiting lane in which the green light is turned on, the traffic light of the other lane with the waiting vehicle is turned on so that there is no waiting of the unnecessary vehicle of the vehicle at the intersection so that the waiting signal for the intersection It is effective in preventing traffic congestion.
