Wrong-way vehicle prevention device

Abstract

To provide a wrong-way vehicle intrusion prevention device. The solution is equipped with wrong-way driving detection sensors 1 and 2 that detect the direction of travel of a vehicle and determine whether it is driving in the wrong direction, water curtain forming devices 3 and 4 that form a water curtain on the road when detected, and a lighting device 6 that projects a warning sign onto the water curtain. These water curtain devices are arranged in multiple stages to provide warnings in stages, and vehicles that ignore the warning and attempt to pass through are physically prevented from proceeding by a mechanical puncture device 5 that punctures the tires only when driving in the wrong direction. Furthermore, a control device controls each device in sequence to ensure reliable operation. Conventional signs and warning displays cannot completely prevent wrong-way driving due to oversight or mistaken belief, but by combining a strong visual warning with a final physical block, wrong-way driving vehicles are reliably prevented from entering.

Description

[Technical Field]

[0001] This invention relates to the field of road traffic safety, and in particular to a device that reliably detects vehicles driving in the wrong direction on expressways and general roads, and prevents them by combining visual warnings and physical deterrence. [Background technology]

[0002] Conventional measures to prevent wrong-way driving include road markings, warning signs, rotating lights, warning lights, and audio warnings using wrong-way driving detection sensors. However, these methods all depend on the driver's visibility and attention, and there is a problem in that they cannot completely prevent wrong-way driving due to oversight or mistaken assumptions. Summary of the Invention [Problem to be solved by the invention]

[0003] This device aims to reliably prevent wrong-way vehicles from entering the road by combining (1) a strong visual warning and (2) a final physical deterrent, which cannot be prevented by conventional warnings alone. [Means for solving the problem]

[0004] The wrong-way vehicle intrusion prevention device of the present invention has the following configuration. 1. Wrong-way driving detection sensor: Detects the direction of travel of vehicles using radar, AI cameras, infrared sensors, etc., and identifies vehicles driving in the wrong direction. 2.Water curtain forming device It activates when wrong-way driving is detected, forming a vertical water curtain on the road. 3.Lighting device for warning display A lighting device for projecting warning signs such as "wrong way driving" and "stop" onto a water screen. 4.Multi-stage arrangement The water curtain forming device is installed in a plurality of stages on the road, and a warning is given in stages to a wrong-way vehicle that is about to pass. 5. Puncture device A spike unit that physically stops vehicles that ignore the above warnings and pass through. When driving normally, the spikes (pins) of this puncture device are pushed by the tire and stored under the road surface, but when driving in reverse, they are not stored and the spikes puncture the tire, making it difficult to drive. The mechanical system prevents malfunctions and ensures reliable operation even in the event of a power outage or control system failure. 6. Control Device Based on the detection results from the sensor, the water curtain device and lighting device are controlled sequentially. [Effects of the Invention]

[0005] The present invention provides the following excellent effects: 1. Water curtains and projection displays provide intuitive and highly visible warnings. 2. Stepwise control is possible: visual warning → re-warning → physical blocking. 3. The puncture device can prevent serious accidents. 4. It is mechanical and the spikes (pins) of the puncture device are stored during normal passage, so there is a low risk of malfunction. 5. Linking with the road management system enables quick reporting and secondary response. [Brief explanation of the drawings]

[0006] [Figure 1] 1 is a diagram showing an embodiment of a wrong-way vehicle intrusion prevention device according to the present invention; DETAILED DESCRIPTION OF THE INVENTION

[0007] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. However, the present invention is not limited to these examples and includes modifications that can be easily conceived by those skilled in the art. As shown in Figure 1, the wrong-way driving prevention device of this invention is composed of a wrong-way driving detection sensor (1) that detects wrong-way driving vehicles, a first water curtain forming device (3) that forms a water curtain on the road when wrong-way driving is detected, a second water curtain forming device (4) that operates in response to a second detection, a wrong-way driving detection sensor (2) placed between the water curtain forming devices, a lighting projection device (6) that displays a warning on the water curtain, and a puncture device (5) that finally stops wrong-way driving vehicles. It also has a control device that controls the operation of each device in an integrated manner. The wrong-way driving detection sensors (1, 2) consist of a radar sensor, an image analysis camera, an infrared sensor, etc., and detect the direction in which the vehicle is traveling to determine whether it is driving in the wrong direction. These sensors are attached to structures such as roadside posts or guardrails and accurately detect vehicles going in the wrong direction. The first water curtain forming device (3) and the second water curtain forming device (4) are made up of nozzle groups that form a water curtain that spreads perpendicular to the road surface, and the water curtain is instantly deployed by a high-pressure pump. The water curtain not only blocks the view but also provides physical and psychological resistance, encouraging the driver to strongly urge themselves to stop. In addition, a lighting projection device can be used to project warning letters or symbols such as "wrong way driving" or "stop" onto the water screen, ensuring high visibility even at night or in bad weather. The puncture device (5) is structured so that the spikes (pins) are pushed by the vehicle tire in the normal running direction and stored under the road surface, and is equipped with a mechanical mechanism to prevent malfunction. If a vehicle enters from the wrong direction, the spikes will not retract, but will puncture the vehicle's tires, making it difficult for it to move forward, physically preventing its progress.The puncture mechanism is mechanical rather than electronically controlled, ensuring reliable operation even in the event of a power outage or control system failure. The control device activates each device in sequence based on the wrong-way driving signals received from the sensors. That is, when the first sensor (1) detects a wrong-way driving vehicle, the first water curtain forming device (3) is activated, giving a strong warning to the driver. If the wrong-way driving vehicle passes without stopping, the second sensor (2) detects this and activates the second water curtain forming device (4) to give another warning. If the vehicle still ignores this and attempts to enter, the puncture device (5) will stop the vehicle. Furthermore, the control device is configured to be able to communicate with an external monitoring system such as a road management center, and can immediately send a notification signal when it detects wrong-way driving. The device of the present invention configured as described above provides multiple safety measures against wrong-way driving vehicles, from visual warnings to physical deterrence, thereby reliably preventing wrong-way driving, something that was difficult to achieve with conventional technology. [Example]

[0008] If a vehicle goes in the wrong direction, the front row of wrong-way detection sensors will determine the direction of travel and activate the water curtain generating device and lighting device. If the driver passes through without stopping, the rear row of water curtain generating devices will issue another warning. If the vehicle continues to run in the wrong direction, the puncture device will puncture the tires of the vehicle to bring it to a stop. [Industrial Applicability]

[0009] The wrong-way driving prevention device of this invention can be applied to any road environment where a vehicle may enter in the wrong direction, such as expressways, general roads, interchanges, junctions, service area entrances and exits, smart ICs, multi-story parking lot entrances and exits, airport premises roads, and logistics facility premises roads. This device combines wrong-way driving detection, visual blocking with a water curtain, highly visible warning with light projection, and physical blocking with a mechanical puncture device, and can be easily added or retrofitted to existing road infrastructure. In addition, the control devices and sensors are compatible with commercially available general road facilities and ITS (Intelligent Transport Systems), so they can be applied to a wide range of road management systems while keeping implementation costs low. Furthermore, serious accidents caused by wrong-way driving are a serious social problem for road managers, and since this device directly contributes to preventing accidents, it is expected to be in high demand as a traffic safety device. Therefore, the present invention can be widely used in the road infrastructure industry and traffic safety equipment industry, and is extremely useful industrially. [Explanation of symbols]
