Abstract

The present invention relates to a system for protecting a pedestrian approaching a crosswalk. Disclosed is a pedestrian safety system comprising: a pedestrian sensing part for sensing and judging whether a pedestrian enters a safety line from the sidewalk or enters the sidewalk from the road; a pedestrian entry direction identification part; a signal identification part for receiving a stop signal and a walk signal from a pedestrian light and identifying the signals; a control part for controlling the pedestrian sensing part, the signal identification part and a sound output part; and the sound output part for outputting a guidance voice by means of the control part. The pedestrian sensing part senses whether the pedestrian enters the safety line from the sidewalk or enters the sidewalk from the road on the basis of the safety line, through a first sensing part, a second sensing part, a third sensing part and a fourth sensing part. After judging whether the pedestrian enters the safety line from the sidewalk or enters the sidewalk from the road by means of a signal of the pedestrian sensing part when the pedestrian light is in a stop signal state, the control part outputs a guidance voice of "It is dangerous, please step back" through the sound output part when it is judged that the pedestrian has entered the safety line from the sidewalk, and outputs or does not output a guidance voice informing of violation of a traffic signal when it is judged that the pedestrian has entered the sidewalk from the road. When sensing a pedestrian, the system senses and judges from which direction the pedestrian enters and then outputs a suitable guidance voice, and distinguishes between humans and fallen leaves, thereby safely protecting pedestrians without malfunction caused by fallen leaves.

Description

횡단보도의 보행자안전시스템Pedestrian safety system at pedestrian crossing
본 발명은 횡단보도에 근접하는 보행자를 보호하기위한 시스템에 관한 것으로서, 보다 상세하게는 보행자감지부를 통하여 안전선을 중심으로 보행자가 인도에서 안전선으로 진입했는지, 차도에서 인도로 진입했는지를 판단할 수 있도록 감지하여 진입방향에 따라 다른 내용의 안내음성 및 경고음을 음향출력부를 통해 출력하여, 사고를 미연에 예방 할 수 있도록 하고, 보행자감지와 눈, 비, 낙엽 등의 감지를 식별하여 시스템 오작동을 예방하는 것에 관한 것이다. The present invention relates to a system for protecting pedestrians approaching a crosswalk, and more particularly, to determine whether a pedestrian enters a safety line from a sidewalk or a sidewalk from a roadway through a pedestrian detection unit. It detects and outputs guide voice and warning sound according to the entrance direction through the sound output unit to prevent accidents in advance, and to detect pedestrian detection and detection of snow, rain and fallen leaves to prevent system malfunction. It's about things.
본 발명은 횡단보도의 보행자안전시스템에 관한 것으로서, 일반적으로 차량이 다니는 도로에는 보행자의 횡단을 위한 횡단보도가 설치되며, 횡단보도에는 보행자가 횡단 가능여부를 인지할 수 있도록 점등신호를 발생시키는 보행자신호등과 횡단보도입구 인도에는 보행자가 안전하게 대기할 수 있는 안전선이 구비되어 있다.The present invention relates to a pedestrian safety system of pedestrian crossings, in general, a pedestrian crossing for the pedestrian crossing is installed on the road on which the vehicle travels, and a pedestrian that generates a lighting signal to recognize whether the pedestrian can cross the pedestrian crossing. Traffic lights and pedestrian crossings are provided with safety lines for pedestrians to wait safely.
그러나, 종래의 횡단보도는 단순히 보행자에게 횡단보도의 신호가 정지인지 보행인지 상황만을 인지하도록 하는 신호기능 만으로 이루어져 있어, 보행자신호등이 정지신호상태에서 횡단보도를 건너기 위해 대기 중인 보행자들이 안전선 밖에서 안전하게 대기해야 하는데 많은 보행자들이 무의식적으로 안전선내로 진입하거나 안전선을 넘어 차도에 까지 진입하여 대기하고 있는 경우가 많아 안전사고가 높은 문제점이 있다.However, the conventional pedestrian crossing is simply composed of a signal function that allows the pedestrian to recognize whether the signal of the pedestrian crossing is stationary or walking, so that pedestrians who are waiting to cross the pedestrian crossing under the stop signal are safely waiting outside the safety line. However, many pedestrians unknowingly enter the safety line or wait to enter the road beyond the safety line has a high safety accident.
상기와 같은 문제점을 해결하기 위하여 선행문헌1 대한민국특허출원번호 10-2006-0037770 및 10-2013-0168933의 내용 및 도면을 살펴보거나 또한 일부 지역에서는 횡단보도입구에 보행자감지부(보행자 진입방향판단 못함)를 설치하고, 보행자신호등의 정지신호상태에서 보행자가 안전선에 진입함을 감지하면(보행자 진입방향판단 못함) ‘위험하니 뒤로 물러서주십시오’ 라고 안내하는 장치가 설치되어 있다.In order to solve the problems described above, look at the contents and drawings of the prior document 1 Korean Patent Application No. 10-2006-0037770 and 10-2013-0168933 or in some areas pedestrian detection unit (does not determine the pedestrian entry direction at the crosswalk entrance) ), And when a pedestrian enters the safety line in the stop signal state such as a pedestrian traffic light (not able to determine the pedestrian's entrance direction), a device is installed to guide you, 'Please stay backward'.
하지만, 이를 살펴보면, 상기 보행자감지부는 보행자를 감지 시 보행자가 인도 쪽에서 안전선으로 진입했는지, 차도 쪽에서 인도로 진입했는지를 판단하지 못하고 어느 쪽에서 진입했건 상관없이 진입한 사실만 감지하여 무조건 ‘위험하니 뒤로 물러서주십시오’라고 안내한다. However, if you look at this, the pedestrian detection unit does not determine whether the pedestrian entered the safety line on the side of the side of India or the side of the roadway when detecting the pedestrian, regardless of which side they entered, unconditionally 'backed off' Please. '
이 경우 횡단보도 건너편에서 정지신호상태에서 신호를 위반하여 보행자가 횡단보도를 건너오거나, 보행신호의 마지막타임 부분에 무리하게 횡단보도를 건너오다 횡단보도를 완전히 건너기전에 보행자신호등이 보행신호에서 정지신호로 바뀌면 보행자가 차도에서 인도로 진입하는 순간 보행자감지부가 보행자를 감지하게 된다. 이때 보행자감지부는 보행자가 차도에서 인도로 진입했음을 판단하지 못하므로 일반적인 감지상태의 안내음성인 ‘위험하니 뒤로 물러서주십시오’ 라고 안내하게 된다.In this case, the pedestrian traffic light stops at the pedestrian signal before the pedestrian crosses the crosswalk or forcibly crosses the crosswalk at the last time of the pedestrian crossing. When the pedestrian enters the sidewalk from the roadway, the pedestrian detection unit detects the pedestrian. At this time, the pedestrian detection unit does not determine that the pedestrian has entered the sidewalk, so the guide voice, which is a general detection state, will be guided as 'Please leave behind dangerous'.
차도에는 많은 자동차들이 빠른 속도로 진행하고 있는데 보행자에게 뒤로 물러나 차도로 다시 진입하라는 뜻이므로 이는 보행자에게 위험요인을 유발시키는 안내가 되는 심각한 문제점이 있다. Many cars on the roadway are moving at a high speed, which means that the pedestrians must step back and re-enter the roadway, which is a serious problem that is a guide for causing a hazard to the pedestrians.
또한, 눈이나 소나기 특히 낙엽이 감지부위로 떨어질 경우 보행자감지부는 이를 감지하여 안내음성을 출력하게 되는데 이에 대한 대책마련이 없어 낙엽 등으로 인한 시스템 오작동이 빈번히 발생하는 문제점이 있다.In addition, when snow or showers, especially fallen leaves fall to the detection site, the pedestrian detection unit detects this and outputs a guide voice. There is no problem in that a system malfunction occurs due to fallen leaves.
또한, 선행문헌2 대한민국특허출원번호 10-2008-0071928을 살펴보면, 도로의 횡단보도 입구에 지주형태로 설치되는 경보기; 및 상기 횡단보도로부터 일정거리 전방에 설치되며, 차량의 근접여부를 감지하여 상기 경보기에 제어신호를 인가하는 차량감지부를 포함하고, 상기 경보기는, 보행자의 상기 횡단보도에의 근접여부 및 횡단여부를 구별하여 제어할 수 있도록 복수의 센서가 포함된 보행자 감지부;로 되어있다. In addition, looking at the prior document 2 Korean Patent Application No. 10-2008-0071928, the alarm is installed in the form of a strut at the entrance of the crosswalk of the road; And a vehicle detecting unit installed at a predetermined distance from the crosswalk and sensing a proximity of the vehicle and applying a control signal to the alarm, wherein the alarm includes whether the pedestrian is close to the crosswalk and whether or not the crossing is performed. Pedestrian detection unit including a plurality of sensors to be able to distinguish and control.
상기 내용 중 ‘상기 경보기는, 보행자의 상기 횡단보도에 근접여부 및 횡단여부를 구별하여 제어할 수 있도록 복수의 센서가 포함된 보행자 감지부;’ 라고 되어있는데, 상기 ‘복수의 센서’ 는, 보행자신호등이 정지신호상태에서 보행자가 인도에서 안전선으로 진입한 건지, 반대로 차도에서 인도로 진입한 건지를 감지 및 판단하는 것이 아니고, 단순히 보행자가 횡단보도의 근접상태에 있는지 횡단보도 내에 있는지를 감지하여 발광등의 밝기를 조정하는 것으로서, In the above contents, the alarm is a pedestrian detection unit including a plurality of sensors to control whether the pedestrian crossing close to the crosswalk and whether or not; 'The plurality of sensors', the pedestrian Instead of detecting and judging whether a pedestrian has entered a safety line from a sidewalk or vice versa under a stop signal, it simply detects whether a pedestrian is in or near a crosswalk and emits light. In adjusting the brightness of the lamp,
이러한 ‘복수센서’를 이용한다 할지라도 보행자신호등이 정지신호상태에서 보행자가 인도에서 안전선으로 진입했는지, 반대로 차도에서 인도로 진입했는지를 감지 및 판단하지 못하고, 보행자감지와 낙엽감지를 구분하지 못하므로 상기선행문헌1에서 지적한 문제점과 동일한 문제점이 있다.Even if the 'plural sensors' are used, the pedestrian traffic light cannot detect and determine whether the pedestrian has entered the safety line from the sidewalk or the sidewalk from the roadway in the stop signal state, and cannot distinguish between the pedestrian detection and the fallen leaf detection. There is the same problem as that pointed out in Prior Art 1.
또한, 선행문헌3 대한민국특허출원번호10-2014-0037131를 살펴보면, 제어유닛보행자를 탐지하여 제어유닛으로 전송하는 적어도 2개의 레이저탐지유닛 제어유닛으로 보행신호를 전달할 수 있는 외부 신호 유닛 제어유닛의 제어에 따라 정해진 방향으로 경고신호를 발생시킬 수 있는 경고신호 유닛 및 감시영역의 영상을 획득하기위한 영상감시 유닛을 포함하고, In addition, prior document 3 Korean Patent Application No. 10-2014-0037131, the control of the external signal unit control unit capable of transmitting a walking signal to at least two laser detection unit control unit for detecting the control unit walker and transmitting to the control unit A warning signal unit capable of generating a warning signal in a predetermined direction and an image surveillance unit for acquiring an image of the surveillance region according to
상기 2개의레이저탐지 유닛은 상기 보행자에 대한 서로 다른 위치정보를 획득하고 그리고 상기 제어유닛은 상기 서로 다른 위치정보에 기초하여 보행자의 상태를 판단하여 상기 경고신호 유닛을 제어하고, 상기 경고신호 유닛은 적어도 2개의 시각신호 유닛을 포함하고, 상기 시각신호 유닛은 방향제어가 가능한 광 신호 유닛이 되는 것을 특징으로 하는 지능형 횡단보도 보행자 보호 장치라고 되어있다. The two laser detection units acquire different positional information about the pedestrian, and the control unit determines the state of the pedestrian based on the different positional information to control the warning signal unit, and the warning signal unit An intelligent pedestrian crossing pedestrian protection device comprising at least two visual signal units, wherein the visual signal unit is an optical signal unit capable of direction control.
상기 내용 중 ‘보행자를 탐지하여 제어유닛으로 전송하는 적어도 2개의 레이저탐지유닛으로 표기되어 있고 또 다른 내용을 보면 ‘2개의레이저탐지 유닛은 상기 보행자에 대한 서로 다른 위치정보를 획득하고’ 라고 되어있는데, 도면을 대조하여 상세내용을 살펴보면 상기 ‘2개의 레이저탐지 유닛’ 은, 보행자신호등이 정지신호상태에서 보행자가 인도에서 안전선으로 진입한 건지, 반대로 차도에서 인도로 진입한 건지를 감지 및 판단하는 것이 아니고, 단순히 보행자가 횡단보도로부터 가까이 위치하는지 조금 떨어져 위치하는지를 감지하여 그에 따른 시각신호를 하는 것으로서, In the above description, it is marked as at least two laser detection units for detecting a pedestrian and transmitting them to a control unit. In another, the two laser detection units acquire different position information about the pedestrian. When comparing the drawings and looking at the details, the two laser detection units detect and determine whether a pedestrian has entered the safety line from the sidewalk while the pedestrian traffic light stops and, on the contrary, the sidewalk has entered the sidewalk. Rather, it simply detects whether a pedestrian is located near or slightly away from the crosswalk and generates a visual signal accordingly.
이러한 ‘2개의레이저탐지 유닛’을 이용한다 할지라도 보행자신호등이 정지신호상태에서 보행자가 인도에서 안전선으로 진입했는지, 반대로 차도에서 인도로 진입했는지를 감지 및 판단하지 못하며, 보행자감지와 낙엽감지를 구분하지 못하므로 상기 선행문헌1 에서 지적한 문제점과 동일한 문제점이 있다.Even when using the 'two laser detection units', the pedestrian traffic light does not detect and judge whether the pedestrian has entered the safety line from the sidewalk or the sidewalk from the roadway in the stop signal state, and does not distinguish between the pedestrian detection and the fallen leaf detection. Therefore, there is the same problem as the problem pointed out in the prior document 1.

To solve this problem, when a pedestrian traffic light stops, it detects and judges whether a pedestrian has entered a safety line from a side of a safety line or enters a sidewalk from a roadway. When the output of the pedestrian is guided to the side of the road, and the pedestrian is determined to enter the sidewalk, the voice should be output according to the direction of entry.
또한, 보행자감지와 눈, 비, 낙엽 등 감지를 구분하여 눈, 비, 낙엽이 감지될 경우에는 안내음성이 출력되지 않아야 한다. In addition, when the snow, rain, and fallen leaves are detected by distinguishing the pedestrian detection from the detection of snow, rain, and fallen leaves, the guide voice should not be output.

As to prevent the malfunction of the system due to snow, rain, fallen leaves, etc. detected by the pedestrian detection unit 20,
도9, 도10을 살펴보면, 횡단보도의 보행자를 보호하는 횡단보도의 보행자안전시스템에 있어서,        9 and 10, in the pedestrian safety system of the pedestrian crossing to protect the pedestrians of the pedestrian crossing,
횡단보도(13)입구에 설치되며, 보행자신호등(12)이 정지신호상태에서 안전선(15)을 기준으로 사람의 존재 또는 통과를 감지하거나 낙엽을 감지하여 감지지속시간체크부(80)에 신호를 전송하는 보행자감지부(20);        Installed at the crosswalk 13, the pedestrian traffic light 12 detects the presence or passage of a person based on the safety line 15 in the stop signal state or detects the fallen leaves to signal the detection duration check unit 80. A pedestrian detecting unit 20 for transmitting;
신호등감지부(50) 또는 신호등제어부(62)로부터 신호를 전달받아 보행자신호등(12)이 정지신호인지 보행신호인지를 식별하는 신호식별부(42);       A signal identification unit 42 which receives a signal from the traffic light detection unit 50 or the traffic light control unit 62 and identifies whether the pedestrian traffic light 12 is a stop signal or a walking signal;
상기 보행자감지부(20)로부터 신호를 전달받아 상기 보행자감지부(20)의 감지지속시간을 체크하는 감지지속시간체크부(80);       A detection duration check unit 80 which checks the detection duration of the pedestrian detection unit 20 by receiving a signal from the pedestrian detection unit 20;
상기 감지지속시간체크부(80)로부터 신호를 전달받아 보행자감지부(20)가 낙엽을 감지했는지 또는 보행자가 안전선(15)에 진입을 감지했는지를 식별하는 보행자/낙엽식별부(70);        A pedestrian / fallen leaves identification unit 70 for receiving a signal from the detection duration check unit 80 and identifying whether the pedestrian detection unit 20 detects fallen leaves or whether a pedestrian detects entry into the safety line 15;
상기 신호식별부(42)의 보행자신호등(12)이 정지신호상태에서 상기 보행자/낙엽식별부(70)의 보행자가 안전선(15)에 진입했음을 식별 시 음향출력부(40)를 통해 그에 대응되는 안내음성 또는 경고음이 출력되도록 하는 제어부(41);       When the pedestrian traffic light 12 of the signal identification unit 42 detects that the pedestrian of the pedestrian / deciduous identification unit 70 has entered the safety line 15 in the stop signal state, the pedestrian traffic light 12 corresponds to that through the sound output unit 40. A controller 41 for outputting a guide sound or a warning sound;
상기 제어부(41)의 제어에 의해 안내음성 또는 경고음을 출력하는 음향출력부(40);를 포함하는 것을 특징으로 하며,       And a sound output unit 40 outputting a guide sound or a warning sound under the control of the control unit 41.
또한, 상기 보행자/낙엽식별부(70)는, 감지지속시간체크부(80)의 감지지속시간이 설정해 놓은 시간미만이면 낙엽을 감지한 것으로 식별하고, 설정해 놓은 시간이상이면 보행자가 안전선에 진입한 것으로 식별하며,       In addition, the pedestrian / deciduous identification unit 70, if the detection duration time of the detection duration check unit 80 is less than the time set by the detection of the fallen leaves, if more than the set time pedestrian enters the safety line To be identified as
상기 제어부(41)는, 보행자/낙엽식별부(70)가 낙엽을 감지했음을 식별 시 음향출력부(40)를 통해 안내음성 또는 경고음이 출력되지 않도록 하여야 할 것이다.        The controller 41 should prevent the guide sound or the warning sound from being output through the sound output unit 40 when identifying that the pedestrian / fallen leaves identification unit 70 detects the fallen leaves.
상기 설정해 놓은 시간이란 예를 들어 시간을 2초로 설정해 놓았다고 가정할 경우 낙엽이 떨어지면서 보행자감지부(20)의 감지구간을 지나가는 시간은 2초 미만이고, 보행자가 안전선(15)에 진입한 상태를 감지하는 경우는 감지지속시간이 2초 이상이므로 즉 보행자감지부(20)가 객체를 감지하여 감지지속시간이 2초 미만이면 낙엽, 눈, 비 등을 감지한 것으로 판단하고 감지지속시간이 2초 이상이면 보행자를 감지한 것으로 판단하게 될 것이다.        For example, when the time is set to 2 seconds, the time passed by the falling section of the detection section of the pedestrian detection unit 20 is less than 2 seconds, and the pedestrian enters the safety line 15. In the case of detecting, since the detection duration is more than 2 seconds, that is, the pedestrian detection unit 20 detects an object, and if the detection duration is less than 2 seconds, it is determined that it has detected fallen leaves, snow, and rain, and the detection duration is 2 seconds. If abnormal, the pedestrian will be detected.
또한, 다른 방법으로서 상기 보행자/낙엽식별부(70)는, 감지지속시간체크부(80)의 감지지속시간이 설정해 놓은 시간미만이면 보행자가 차도(10)에서 인도(11)로 진입한 것으로 식별하고, 설정해 놓은 시간이상이면 보행자가 인도(11)에서 안전선(15)에 진입한 것으로 식별하며,        As another method, the pedestrian / fallen leaves identification unit 70 identifies that the pedestrian enters the sidewalk 11 from the roadway 10 if the detection duration time of the detection duration check unit 80 is less than the time set. If more than the set time, the pedestrian is identified as entering the safety line 15 in the sidewalk 11,
상기 제어부(41)는, 보행자/낙엽식별부(70)의 보행자가 차도(10)에서 인도(11)로 진입한 것으로 식별 시 음향출력부(40)를 통해 그에 대응되는 안내음성 또는 경고음이 출력되도록 하거나 출력되지 않도록 할 수 있을 것이다.       The control unit 41 outputs a guide sound or a warning sound corresponding to the pedestrian / leaf identification unit 70 through the sound output unit 40 when the pedestrian is identified as entering the sidewalk 11 from the roadway 10. You can either enable or disable the output.
또한, 보행자감지부(20)가 감지한 객체가 낙엽인지, 보행자가 차도(10)에서 인도(11)로 진입했는지, 보행자가 인도(11)에서 안전선(15)에 진입했는지를 판단하기 위한 것으로서, 낙엽이 보행자감지구역을 지나 떨어질 때는 2초미만이며 보행자가 차도(10)에서 인도로 진입하면서 보행자감지구역을 지나가는 시간은 2초에서 3초 사이이며 보행자가 인도(11)에서 안전선(15)에 진입한 상태에서는 3초 이상 머무르게 될 것이다.        In addition, to determine whether the object detected by the pedestrian detection unit 20 is fallen leaves, whether the pedestrian entered the sidewalk 11 from the roadway 10, or whether the pedestrian entered the safety line 15 from the sidewalk 11. When the fallen leaves fall through the pedestrian detection zone, it is less than 2 seconds, and the time when the pedestrian enters the sidewalk from the roadway (10) and passes through the pedestrian detection zone is between 2 and 3 seconds, and the pedestrian is on the safety line (15). After entering, you will stay for more than 3 seconds.
