Description

역주행 차량 방지 시스템Reverse Driving Prevention System
본 발명은 역주행 차량 방지 시스템에 관한 것으로, 구체적으로는, 일방통행도로에서 역주행 차량을 방지하기 위한 시스템에 관한 것이다.The present invention relates to a system for preventing a reverse vehicle, and more particularly, to a system for preventing a reverse vehicle on a one-way road.
일반적으로, 국도, 지방도로, 고속도로 휴게소 및 인터체인지 등은 진입로와 진출로가 구별되어 일방통행도로가 설치되며, 차량의 역주행 진입시에 이를 알리기 위한 경고수단이 동작한다. 최근 들어, 차량의 증가와 더불어 전국 도로망의 확충이 가속화 됨에 따라 증가되는 역주행 차량 사고의 발생을 감소시키기 위한 노력이 더욱 필요하며, 그 노력이 다양하게 이루어 지고 있다. In general, national roads, provincial roads, highway rest areas, and interchanges are divided into access roads and exit roads, and one-way roads are installed. Recently, as the number of vehicles increases and the expansion of the national road network is accelerated, more efforts are needed to reduce the occurrence of increased driving vehicle accidents, and various efforts have been made.
또한, 백화점, 마트, 시장, 병원, 기업 등의 주차장에는 차량의 역진입/진출을 주변의 차량 및 사람들에게 알리기 위하여 경광등이 설치되어 있다. 위와 같은 건물들은 도시의 곳곳에 늘어나고 건물의 크기가 거대화 되고 있는 추세이기 때문에, 건물의 주차장은 대부분 차로가 건물의 모양을 따라 곡선 형태로 설치되어 양방향 주행을 하게 되어, 손님들의 착각을 불러일으키며 역주행 사고를 유발할 가능성이 높다. In addition, the parking lot of department stores, marts, markets, hospitals, companies, etc. is provided with a warning light to inform the surrounding vehicles and people of the reverse entry / exit of the vehicle. As the above buildings are increasing in various parts of the city and the size of the buildings is increasing, most of the parking lots of the buildings are installed in a curved shape along the shape of the building, which leads to two-way driving, which induces the illusion of customers and reverse driving. It is likely to cause an accident.
위와 같이, 도로의 정방향에 대하여 차량이 역방향으로 주행하여 발생되는 역주행 사고는, 대형 교통사고를 유발 또는 도로 정체로 이어질 가능성이 매우 높아, 각별한 방지 대책을 수립할 필요성이 있다. As described above, the reverse driving accident caused by the vehicle traveling in the reverse direction with respect to the forward direction of the road is very likely to lead to a large traffic accident or congestion of the road, and there is a need to establish a special preventive measure.
이러한 일방통행도로가 필요한 장소에서는, 일방통행도로를 역방향으로 주행하는 운전자를 통제하기 위해서 일방통행도로 진입금지 표시판을 설치하거나, 도로면에 주행방향을 알리는 화살표를 표시하여 운전자에게 인식을 시켜주려는 노력을 하고 있다. 덧붙여서, 최근에는 일방통행도로의 진입로나 역주행 사고가 빈발하는 구간에 적외선 감지기 또는 영상 감지기를 한 쌍으로 설치한 역주행 방지 시스템을 이용해, 차량의 주행을 감지하는 순서에 따라 차량의 진행 방향을 판단하도록 하고 있다. In places where such one-way roads are needed, in order to control drivers driving in the reverse direction of one-way roads, an effort to install a one-way road sign or display an arrow indicating the driving direction on the road surface to make the driver aware. Doing In addition, recently, by using a reverse driving prevention system in which a pair of infrared sensors or an image sensor are installed in an access road on a one-way road or a section in which a reverse driving accident occurs frequently, the driving direction of the vehicle is determined in order of detecting the driving of the vehicle. Doing.
하지만, 이러한 종래의 역주행 차량 방지 시스템은, 적외선 감지 기능 또는 영상 감지 기능이 도로 상의 기후 변화 및 주변 조명상태의 변화에 취약한 형태로 이루어져 있으며, 특히 한 쌍의 감지기가 차량의 주행을 감지하는 순서에 따라 차량의 주행 방향을 판단하는 것으로 차량이 한 쌍의 감지기 모두를 지나야 차량의 주행 방향을 알 수 있으므로 신속한 판단이 어렵다는 문제점이 있다. 또한 종래의 역주행 차량 방지 시스템은, 기후 변화가 심하게 발생하거나 가로등 및 차량 조명등으로 인한 영향 또는 차량이 아닌 다른 물체를 감지하는 오류를 범할 가능성이 있다.However, such a conventional anti-driving vehicle prevention system has an infrared detection function or an image detection function that is vulnerable to changes in road climate and ambient light conditions, and in particular, a pair of detectors detects the driving of a vehicle. Accordingly, there is a problem that it is difficult to quickly determine the driving direction of the vehicle because the driving direction of the vehicle may be known only when the vehicle passes all of the pair of detectors. In addition, the conventional anti-vehicle vehicle prevention system is likely to commit a severe climate change, the effects of streetlights and vehicle lights, or detect errors other than the vehicle.

도 1 및 도 2를 참조하면, 본 발명의 일 실시예에 따른 역주행 차량 방지 시스템(100)은, 일방통행도로(10)에서 역주행 차량을 방지하기 위한 시스템으로, 일방통행도로(10)에 설치되어 정상주행 차량을 감지하는 정방향 감지용 센서부(110), 정방향 감지용 센서부(110)와 미리 정해진 거리를 두고 일방통행도로(10)에 설치되어 역주행 차량을 감지하는 역방향 감지용 센서부(120), 정방향 감지용 센서부(110) 및 역방향 감지용 센서부(120)로부터 전송되는 감지신호를 수신하는 제어부(130)를 포함할 수 있다. 1 and 2, the reverse driving vehicle prevention system 100 according to an embodiment of the present invention is a system for preventing the reverse driving vehicle on the one-way street 10, and installed on the one-way road 10. And a forward direction sensor unit 110 for detecting a normal driving vehicle and a forward direction sensor unit 110 installed at a one-way road 10 at a predetermined distance from the forward direction sensor unit 110 to detect a reverse driving vehicle ( 120, the controller 130 may receive a detection signal transmitted from the forward sensing sensor unit 110 and the reverse sensing sensor unit 120.
구체적으로, 정방향 감지용 센서부(110)는 일방통행도로(10)의 일정 감지구간 내에서 정방향으로부터 들어오는 차량을 감지하고, 역방향 감지용 센서부(120)는 일방통행도로(10)의 일정 감지구간 내에서 역방향으로부터 들어오는 차량을 감지할 수 있다. 이때, 제어부(130)는 정방향 감지용 센서부(110) 및 역방향 감지용 센서부(120)가 감지됨에 따라 정상주행 차량 또는 역주행 차량으로 판단할 수 있다. 또한, 제어부(130)는 본 발명에 따른 역주행 차량 방지 시스템(100)의 각 부를 총괄적으로 제어할 수 있다. Specifically, the forward direction sensor unit 110 detects a vehicle coming from the forward direction in a certain sensing section of the one-way road 10, the reverse direction sensor unit 120 detects a schedule of the one-way road 10 The vehicle coming from the reverse direction can be detected within the section. In this case, the controller 130 may determine that the vehicle is a normal driving vehicle or a reverse driving vehicle as the forward sensing sensor unit 110 and the reverse sensing sensor unit 120 are detected. In addition, the controller 130 may collectively control each part of the anti-driving vehicle prevention system 100 according to the present invention.
제어부(130)는 진입하는 차량이 역방향 차량이라고 판단했을 시에 경고 신호를 출력할 수 있다. 이때, 역주행 차량 방지 시스템(100)는 수신된 경고 신호에 따라 역주행 차량에 알림 메시지를 시각적 및/또는 청각적으로 표시하는 제1 경고 표시부(141)와 정상주행 차량에 알림 메시지를 시각적 및/또는 청각적으로 표시하는 제2 경고 표시부(143)를 포함할 수 있다. The controller 130 may output a warning signal when it is determined that the entering vehicle is the reverse vehicle. In this case, the reverse driving vehicle prevention system 100 may visually and / or display the notification message to the normal driving vehicle and the first warning display unit 141 for visually and / or audibly displaying the notification message on the reverse driving vehicle according to the received warning signal. It may include a second warning display unit 143 that displays audibly.
무선통신모듈(149)은 일방통행도로(10)에서 정상주행 및 역주행 차량을 감지하는 제어부(130)와 관제센터(150)간의 역주행에 관한 정보를 송수신할 수 있다.The wireless communication module 149 may transmit / receive information on reverse driving between the control unit 130 and the control center 150 for detecting normal driving and reverse driving vehicles on the one-way road 10.
일방통행도로(10)에서 차량이 정방향으로 진입하면, 제어부(130)는 역방향 감지용 센서부(120)에 앞서 정방향 감지용 센서부(110)에 의해 차량이 감지됨에 따라 감지된 차량을 정상주행 차량으로 판단할 수 있다. When the vehicle enters the forward direction on the one-way road 10, the controller 130 drives the vehicle detected as the vehicle is detected by the forward sensing sensor 110 before the reverse sensing sensor 120. Judging by the vehicle.
이때, 제어부(130)는 역방향 감지용 센서부(120)에 앞서 정방향 감지용 센서부(110)에 의해 차량이 감지되었기 때문에, 미리 정해진 시간 동안 역방향 감지용 센서부(120)를 전기적으로 오프(OFF)시킬 수 있다. In this case, since the vehicle is sensed by the forward sensing sensor unit 110 prior to the reverse sensing sensor unit 120, the controller 130 electrically turns off the reverse sensing sensor unit 120 for a predetermined time. OFF).
다시 말하면, 정방향 감지용 센서부(110)에 의해 차량이 감지되면 역방향 감지용 센서부(120)를 전기적으로 오프(OFF)시켜 정상주행 차량은 미리 정해진 시간 동안 역방향 감지용 센서부(120)를 지나쳐도 어떠한 경고 신호 없이 통과될 수 있다. 즉, 제어부(130)는 미리 정해진 시간이 지나면 역방향 감지용 센서부(120)를 다시 온(ON) 상태로 변경하여, 다시금 역주행 차량을 감지할 수 있도록 한다.In other words, when the vehicle is detected by the forward sensing sensor unit 110, the reverse sensing sensor unit 120 is electrically turned off, so that the normal driving vehicle turns off the reverse sensing sensor unit 120 for a predetermined time. It can be passed without any warning signal. That is, the controller 130 changes the reverse sensing sensor unit 120 back to an ON state after a predetermined time passes, so that the driving vehicle can be detected again.
미리 정해진 시간은 정방향 감지용 센서부(110)와 역방향 감지용 센서부(120) 사이의 이격거리에 기초하여 설정될 수 있다. 즉, 미리 정해진 시간은 감지구간, 유동차량, 센서부 간의 이격거리 등을 계산에 입각하여 산출하고, 이를 고려해 제어부에 저장될 수 있다. The predetermined time may be set based on a separation distance between the forward sensing sensor unit 110 and the reverse sensing sensor unit 120. That is, the predetermined time may be calculated based on a calculation of a sensing section, a flow vehicle, and a separation distance between the sensor units, and may be stored in the controller in consideration of this.
상기와 같은 이유로, 제어부(130)는 역방향 감지용 센서부(120)에 의해 차량이 감지되면 감지된 차량을 역주행 차량으로 판단할 수 있다.For the same reason as described above, when the vehicle is detected by the reverse sensing sensor unit 120, the controller 130 may determine the detected vehicle as the reverse driving vehicle.
따라서, 차량이 진입하고 최초에 역방향 감지용 센서부(120)가 감지되면 제어부(130)는 즉각적으로 경고 신호를 생성할 수 있다. 하지만, 차량이 진입한 후 최초에 정방향 감지용 센서부(110)에 의해 차량이 감지되면 제어부(130)는 미리 정해진 시간 동안 역방향 감지용 센서부(120)를 전기적으로 오프(OFF)시킬 수 있다. Therefore, when the vehicle enters and the first reverse sensing sensor unit 120 is detected, the controller 130 may immediately generate a warning signal. However, if the vehicle is first detected by the forward direction sensor unit 110 after the vehicle enters, the controller 130 may electrically turn off the reverse direction sensor unit 120 for a predetermined time. .
요약하면, 본 발명에 따른 역주행 차량 방지 시스템(100)은, 일방통행도로(10)에서 정상주행 차량만을 통과시키는 구성을 통해, 역주행 차량이 감지되는 순간 역주행임을 즉각적으로 판단할 수 있는 시스템에 관한 것이다. 이는, 정상주행/역주행 차량에 따라 즉시 대응하므로 종래의 역주행 차량 방지 시스템의 오류를 막을 수 있다. In summary, the reverse driving vehicle prevention system 100 according to the present invention, through a configuration that passes only the normal driving vehicle on the one-way road 10, a system that can immediately determine that the reverse driving the moment the reverse driving vehicle is detected will be. This can prevent an error of the conventional anti-vehicle vehicle prevention system because the vehicle immediately responds to the normal / reverse vehicle.
일방통행도로(10)에서 역주행 차량이 진입하면, 제어부(130)는 역주행 및 정상주행 차량의 운전자, 관제센터(150) 등에 역주행 차량을 알리는 경고 신호를 생성할 수 있다. When the reverse traveling vehicle enters the one-way street 10, the controller 130 may generate a warning signal for notifying the reverse traveling vehicle of the driver of the reverse driving and the normal driving vehicle, the control center 150, and the like.
도 3은 도 1의 역주행 차량 방지 시스템에서 제1 및 제2 경고 표시부에 적용되는 경고 메시지를 예시한 도면이다.FIG. 3 is a diagram illustrating a warning message applied to the first and second warning display units in the reverse driving prevention system of FIG. 1.
도 3을 참조하면, 제1 경고 표시부(141) 및 제2 경고 표시부(143)는 제어부(130)로부터 역주행 차량이라고 판단되면, 정상주행 차량과 역주행 차량의 운전자 모두에게 주의 또는 경고 메세지를 출력할 수 있다. 이때, 정상주행 차량인지 역주행 차량인지에 따라 각기 다른 메시지를 포함할 수 있다. Referring to FIG. 3, when it is determined that the first warning display unit 141 and the second warning display unit 143 are the reverse driving vehicle from the controller 130, the first warning display unit 141 and the second warning display unit 143 may output a caution or warning message to both the driver of the normal driving vehicle and the reverse driving vehicle. Can be. In this case, different messages may be included depending on whether the vehicle is a normal driving vehicle or a reverse driving vehicle.
구체적으로, 제1 경고 표시부(141)는 일방통행도로(10)의 역방향 진입 측에 설치되어고 제어부(130)에 의한 경고 신호의 생성시 역주행 차량의 운전자에게 역주행 차량 진입금지를 알리는 메시지를 시각적으로 또는 청각적으로 표시할 수 있다. 즉, 제1 경고 표시부(141)는 역주행 차량의 운전자가 인지할 수 있는 방향에 설치되어 역주행 차량의 운전자를 경고할 수 있다. 제1 경고 표시부(141)는 역주행 차량의 운전자에게 역주행을 경고하거나 진입을 금지할 수 있으며, 정주행 차량이 접근해옴을 경고할 수 있다. 예컨대, 역주행 차량의 운전자에게 '역주행!! 진입 금지!!'라는 경고 메시지를 출력할 수 있다. 물론, 경고 메시지가 스피커를 통해서 음성 형태로도 출력될 수 있다. 따라서, 역주행 차량 운전자는 제1 경고 표시부(141)에 의한 경고를 통해 해당 차량이 역주행 중임을 인지하여 경로를 사전에 변경할 수 있게 된다.Specifically, the first warning display unit 141 is installed on the reverse entry side of the one-way road 10 and visually displays a message informing the driver of the reverse driving vehicle not to enter the driving vehicle when generating the warning signal by the controller 130. It can be displayed as audible or audible. That is, the first warning display unit 141 may be installed in a direction in which the driver of the reverse driving vehicle can recognize the driver of the reverse driving vehicle. The first warning display unit 141 may warn the driver of the reverse driving vehicle or prohibit entry, and may warn the approaching vehicle. For example, if a driver of a car is running, You can print a warning message that says "Do not enter !!". Of course, the warning message may be output in the form of voice through the speaker. Accordingly, the driver of the reverse driving vehicle may change the route in advance by recognizing that the vehicle is in reverse driving through the warning by the first warning display unit 141.
한편, 제2 경고 표시부(143)는 일방통행도로(10)의 정방향 진입 측에 설치되고 제어부(130)에 의한 경고 신호의 생성시 정상주행 차량의 운전자에게 역주행 차량 접근주의를 알리는 메시지를 시각적으로 또는 청각적으로 표시할 수 있다. 즉, 제2 경고 표시부(143)는 정상주행 차량의 운전자가 인지할 수 있는 방향에 설치되어 역주행 차량이 접근하는 사실을 정상주행 차량의 운전자에게 주의를 줄 수 있다. 제2 경고 표시부(143)는 정상주행 차량의 운전자에게 역주행 차량이 접근해옴을 경고할 수 있다. 예컨대, 정상주행 차량의 운전자에게 '역주행 차량 접근 주의!!'라는 주의 메시지를 출력할 수 있다. 물론, 주의 메시지가 스피커를 통해서 음성 형태로도 출력될 수 있다. 따라서, 정상주행 차량 운전자는 제2 경고 표시부(143)에 의한 경고를 통해 상황에 대처하고 사고를 미연에 방지할 수 있게 된다. Meanwhile, the second warning display unit 143 is installed on the forward entry side of the one-way road 10 and visually displays a message informing the driver of the normal driving vehicle of approaching vehicle approaching attention when the warning signal is generated by the controller 130. Or audibly. That is, the second warning display unit 143 may be installed in a direction that can be recognized by the driver of the normal driving vehicle to give attention to the driver of the normal driving vehicle that the reverse driving vehicle approaches. The second warning display unit 143 may warn the driver of the normal driving vehicle that the reverse driving vehicle is approaching. For example, the driver may output a warning message 'Caution for approaching vehicle approaching !!' to a driver of a normal driving vehicle. Of course, the warning message may be output in the form of voice through the speaker. Therefore, the normal driving vehicle driver can cope with the situation and prevent the accident through the warning by the second warning display unit 143.
또한, 제1 경고 표시부(141) 및 제2 경고 표시부(143)의 경고 수단은 역주행/정상주행 차량의 운전자들이 시각적으로 인지할 수 있도록 경고문구를 표시하는 디스플레이수단 또는 위험을 알리는 경광등이 설치될 수 있으며, 청각적으로 인지할 수 있도록 진입금지를 알리는 경고음 발생기가 선택적으로 설치될 수 있다. In addition, the warning means of the first warning display unit 141 and the second warning display unit 143 may be provided with a display means for displaying a warning message or a warning light to indicate a danger so that drivers of the reverse driving / normal driving vehicle may be visually recognized. In addition, a warning sound generator for notifying entry may be selectively installed so as to recognize the sound.
즉, 본 발명에 따른 역주행 차량 방지 시스템(100)은 일방통행도로(10)에 진입한 차량 주행 중 반대 방향에서 접근해오는 차량(역주행 차량)이 역주행 감지용 센서부를 통과하게 되면, 역주행 차량뿐만 아니라 정상주행 차량에도 경고 또는 주의 신호를 출력하여 사고를 방지할 수 있다. That is, the reverse driving vehicle prevention system 100 according to the present invention, if the vehicle approaching in the opposite direction of the vehicle driving entering the one-way road 10 (reverse running vehicle) passes through the reverse driving detection sensor unit, as well as the reverse driving vehicle Warnings or caution signals can also be output to normal driving vehicles to prevent accidents.
도 1 및 도 5를 참조하면, 역주행 차량 방지 시스템(100)은 일방통행도로(10)의 정방향 진입 측에 설치되고 경고 신호의 생성시 작동하여 정상주행 차량 또는 역주행 차량의 진입을 막는 차단봉(145)을 더 포함할 수 있다. 이때, 차단봉(145)은 도 5에 도시된 바와 다르게 역방향 진입 측에 설치될 수도 있다.1 and 5, the reverse driving vehicle prevention system 100 is installed on the forward entry side of the one-way road 10 and operates when generating a warning signal to block the entry of the normal driving vehicle or the reverse driving vehicle 145. ) May be further included. In this case, the blocking rod 145 may be installed on the reverse entry side differently from that shown in FIG. 5.
즉, 본 발명의 구성상 역주행 차량 진입을 즉각적으로 알 수 있으므로, 제어부(130)는 센싱된 차량이 역주행이라고 판단되면, 정상주행 차량의 안전과 충돌사고의 위험을 방지하기 위해 정상주행 차량의 진입을 막도록 하는 차단봉(145)이 작동할 수 있다.
