Description

Technical Field

[0001] This invention belongs to the field of traffic safety technology and relates to an intelligent safety barrier device and its implementation method for highways. Background Technology

[0002] With the continuous expansion of the highway network and the increasing speed of vehicle traffic, highways, while ensuring traffic efficiency, also face increasingly severe challenges to driving safety. Especially in mountainous, hilly, or bridge-tunnel junction areas with complex terrain, sudden natural disasters such as rockfalls, landslides, mudslides, and roadbed collapses occur frequently. Furthermore, major traffic accidents on highways, such as multi-vehicle rear-end collisions, rollovers, tire blowouts, and vehicle fires, are also on the rise.

[0003] When such emergencies occur, due to the high speeds of vehicles on highways, drivers of following vehicles often find it difficult to react effectively in a short time, frequently resorting to emergency braking or rapid lane changes to avoid collisions. However, due to short reaction times, limited visibility, and complex road conditions, these human-induced emergency responses can easily lead to secondary accidents or even chain-reaction collisions, seriously threatening personal and property safety. Existing highway infrastructure typically relies solely on fixed warning signs and monitoring systems, resulting in a weak dynamic response capability to emergencies and the lack of a comprehensive intelligent proactive interception system.

[0004] While some highways have deployed Intelligent Transportation Systems (ITS) to collect and transmit information through video surveillance, dynamic guidance signs, and broadcasting systems, these systems mostly focus on information dissemination and guidance, lacking the ability to physically block or provide flexible buffering for vehicles traveling at high speeds. Especially when drivers are unable to brake or actively control the vehicle in time, there is a lack of active safety protection technology that can effectively intervene and reduce vehicle speed.

[0005] Therefore, there is an urgent need for an intelligent safety barrier technology system for highways that integrates real-time monitoring, intelligent judgment, automatic triggering, and physical buffering. This system should be able to issue timely and effective early warning information in emergency situations and automatically deploy barrier devices when necessary to physically slow down and brake vehicles, thereby effectively avoiding or reducing the severity of traffic accidents. The proposal and implementation of this system will fill a key gap in existing highway traffic safety technologies. Summary of the Invention

[0006] In view of this, the purpose of this invention is to provide an intelligent safety barrier device and its implementation method for highways. During long-term use, highways experience a continuous decline in the stability and durability of their roadbed structure under the influence of vehicle loads, rain, and wind. High-slope sections are prone to disasters such as rockfalls, landslides, mudslides, and roadbed collapses, posing serious challenges to highway driving safety and traffic efficiency. When a vehicle is unable to brake quickly and safely to a stop due to a sudden natural disaster or traffic accident ahead, this invention provides an intelligent safety barrier device and its implementation method for highways, which can effectively assist high-speed vehicles in emergency braking and provide safety assurance for highway vehicles.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A smart safety barrier device for highways, comprising:

[0009] Monitoring and early warning system, triggering system and blocking system;

[0010] in,

[0011] The monitoring and early warning system includes:

[0012] The first gantry is installed on the outer side of the median strip and shoulder of the road. The first gantry is equipped with a first broadcaster, a first sign and a first monitor. The first sign has lighting and flashing prompt functions. The first broadcaster is used for voice broadcasting. The first monitor is used for dynamic monitoring of the driving environment in front of the device.

[0013] The triggering system includes:

[0014] The second gantry is installed on the outer side of the median strip and shoulder of the road. The second gantry is equipped with a second broadcaster, a second sign, a second monitor, and a trigger plate connected by a first rotating shaft. The second sign has lighting and flashing prompt functions. The second broadcaster is used for voice broadcasting. The trigger plate automatically opens after receiving a signal that a vehicle has entered the barrier zone.

[0015] The barrier system includes:

[0016] The posts installed outside the median strip and shoulder are equipped with guide rails, a first sliding device, and a second sliding device. The sliding devices are respectively connected to the first and second barrier cables. The barrier cables pass through the barrier net. The barrier net is reinforced by horizontal cables. The horizontal cables are equipped with buckles. The buckles are connected to a second rotating shaft via a traction rope. The second rotating shaft is driven to rotate by a rotator to control the opening and closing of the barrier net. The barrier net is stored in a storage box. The top of the storage box is connected to a protective plate and an opening and closing plate via a third rotating shaft. The third rotating shaft drives the opening and closing plate to open or close.

[0017] Furthermore, the first monitor works in conjunction with the third monitor on the blocking system to conduct long-distance real-time monitoring and early warning of key road sections.

[0018] Furthermore, the second monitor in the triggering system, in conjunction with the distributed sensors installed under the emergency stopping lane, determines whether a vehicle has entered the barrier lane passage area, thereby triggering the trigger plate to open automatically.

[0019] Furthermore, the first and second sliders slide along the guide rail to expand or retract the barrier net. When not in operation, the barrier net is stored in the storage box, which is closed or opened by the third rotating shaft driving the opening and closing plate.

[0020] Furthermore, the surface of the column is provided with a barrier net indicator to indicate whether a vehicle may enter the emergency stopping lane to use the barrier function.

[0021] A method for implementing intelligent safety barriers on highways includes the following steps:

[0022] S1: The first monitor of the monitoring and early warning system monitors the road driving environment in real time. If a vehicle is detected to have entered the emergency stopping lane, the first broadcast and the first sign will issue a voice and light prompt.

[0023] S2: When the second monitor and the distributed sensor jointly determine that the vehicle has entered the barrier passage area, the first rotating shaft in the trigger system drives the trigger plate to open, and the second broadcaster and the second signboard issue warning information.

[0024] S3: If the vehicle hits the trigger plate, the blocking system is activated, the third rotating shaft drives the opening and closing plate to open, and the blocking net is released.

[0025] S4: The rotator drives the second shaft to rotate, releasing the barrier net through the traction rope. At the same time, the first and second sliders slide along the guide rail to unfold the barrier net to the preset position, forming a flexible barrier structure.

[0026] S5: If the vehicle successfully hits the barrier net and slows down and brakes, wait for on-site rescue; if it fails to brake, the third monitor will identify and trigger the next level of the barrier system to repeat S3 to S5.

[0027] Furthermore, in S2, if the vehicle leaves the barrier zone without colliding with the trigger plate, the system automatically cancels the activation command and returns to standby mode.

[0028] Furthermore, in S5, the third monitor is used to determine whether the vehicle has successfully braked and decide whether to activate the subsequent blocking system.

[0029] Furthermore, all three monitors are equipped with night vision capabilities, enabling them to provide early warnings at night in conjunction with broadcasters and signs.

[0030] The beneficial effects of this invention are as follows:

[0031] This invention provides an intelligent safety barrier device and implementation method for highways, which can effectively compensate for the technical deficiencies of existing highways in responding to emergencies, and improve the safe braking capability of vehicles in special situations and the level of traffic safety in high-speed driving environments. Compared with the prior art, this invention has the following beneficial effects:

[0032] First, this invention uses a monitoring and early warning system to dynamically monitor the environment of key sections of highways, enabling the identification of risks of sudden natural disasters or traffic accidents in the first instance, thus providing early warnings to vehicles behind and improving the efficiency of emergency response to emergencies.

[0033] Secondly, the triggering system set up in this invention can be linked with the vehicle path and environmental perception results. When a vehicle is detected to enter the barrier zone, the triggering device is automatically released to guide the vehicle into the dedicated buffer zone, preparing for subsequent blocking actions and reducing the system response delay.

[0034] Furthermore, this invention employs a multi-level, deployable flexible barrier structure to proactively intervene and physically decelerate a vehicle when it cannot stop safely through its own braking, thereby reducing collision impact and preventing escalation of the accident. Simultaneously, the system is recoverable and scalable, supporting the deployment of subsequent barrier systems even if the first-level barrier fails, thus improving overall fault tolerance and safety assurance levels.

[0035] In addition, the present invention adopts a modular design, with each system working collaboratively yet relatively independently, which facilitates engineering deployment and maintenance, and can be applied to various terrain and road conditions, especially suitable for deployment in road sections with frequent disasters, traffic accidents, or low visibility.

[0036] In summary, this invention not only achieves effective safety intervention for high-speed vehicles under special circumstances, but also provides a brand-new solution for the intelligent prevention and control of sudden traffic incidents on highways, and has high practical value and promising prospects for promotion.

[0050] Please see Figures 1 to 7 This invention aims to provide an intelligent safety barrier device and implementation method for highways, assisting high-speed vehicles in emergency braking and providing safety assurance for highway vehicles. The intelligent safety barrier device and implementation method for highways includes a monitoring and early warning system, a triggering system, a barrier system, and an implementation method.

[0051] The monitoring and early warning system 2 includes two pillars, one gantry 2-1, which is buried outside the median strip 8 and the other shoulder 5 of the road 9. A broadcast device 2-2 is installed on the upper part of the pillar of the first gantry 2-1, and a sign 2-3 and a monitor 2-4 are installed on the crossbar of the first gantry 2-1. The sign 2-3 can achieve night vision through its built-in lighting. In case of emergency, it can flash to remind vehicles behind to slow down or stop. The broadcast device 2-2 and the sign 2-3 remind vehicles behind 1 through voice broadcasts and prompts that they are generally prohibited from entering the emergency stopping lane 6. They can temporarily enter the lane when an emergency requires assisted emergency stopping. The monitor 2-4 can dynamically monitor the driving environment in front of the barrier device. In conjunction with the monitoring of the third monitor 4-13 of the barrier system 4, it can provide long-distance real-time monitoring and early warning for key road sections.

[0052] The triggering system 3 includes two columns, namely the No. 2 gantry 3-3, which are buried outside the median strip 8 and shoulder 5 of the road 9 respectively. The lower part of the No. 2 gantry 3-3 column is connected to the trigger plate 3-2 through the No. 1 rotating shaft 3-1. The No. 2 broadcaster 3-4 is installed on the upper part of the No. 2 gantry 3-3 column. The No. 2 sign 3-5 and the No. 2 monitor 3-6 are installed on the crossbar of the No. 2 gantry 3-3. Under normal circumstances, the trigger plate 3-2 is folded and stored on the column of the second gantry 3-3. When the second monitor 3-6 and the distributed sensors under the road surface of the emergency stopping lane 6 simultaneously detect that a vehicle 1 is passing through the barrier zone, the first pivot 3-1 opens the trigger plate 3-2 by rotating. After the trigger plate 3-2 is opened, it occupies the emergency stopping lane 6, but does not encroach on the space of the carriageway 7. The second sign 3-5 can achieve night vision function through its own lighting. In case of emergency, it can flash to remind the vehicles behind to slow down or stop in an emergency. The second broadcaster 3-4 and the second sign 3-5 remind the vehicles behind 1 through voice broadcasts and prompts that it is generally forbidden to enter the barrier zone of the emergency stopping lane 6. In case of emergency and need to assist in emergency stopping, the vehicle can temporarily enter and drive into the trigger plate 3-2 to activate the barrier system 4.

[0053] The barrier system 4 includes two posts 4-3, which are respectively buried outside the median strip 8 and shoulder 5 of the road 9. A third monitor 4-13 is installed at the top of each post 4-3. Inside each post 4-3 is a guide rail 4-2. A first slider 4-1 and a second slider 4-4, which can slide up and down on the guide rail 4-2, are respectively connected to the ends of a first barrier cable 4-6 and a second barrier cable 4-12. The first barrier cable 4-6, the second barrier cable 4-12, and the cross cable 4-8 pass through the barrier system. Net 4-5 and cross cables 4-8 are equipped with locking buckles 4-7. The bottom of the locking buckle 4-7 is connected to the second rotating shaft 4-11 via a traction rope 4-10. The rotating device 4-9 can drive the traction rope 4-10 to raise and lower the barrier net 4-5 by rotating itself. The barrier net 4-5 is generally stored in the storage box 10. The third rotating shaft 12 located at the top of the storage box 10 is connected to the protective plate 11 and the opening and closing plate 13. The third rotating shaft 12 can drive the opening and closing plate 13 to open and close by rotating itself. Among them, the surface of the column 4-3 is equipped with a barrier net warning sign, and the third monitor 4-13 can dynamically monitor the driving environment near the barrier system 4.

[0054] Example 1: Deployment Process of Intelligent Safety Barrier System for Road Sections with Sudden Rockfalls

[0055] This embodiment is applicable to sections of highways near mountain slopes prone to rockfalls, where the monitoring and early warning system, triggering system, and blocking system of this invention are deployed.

[0056] The workflow is as follows:

[0057] A first gantry and a second gantry are set up on both sides of the target road section. The first gantry is equipped with a first monitor, a first broadcaster and a first sign to monitor road conditions in real time and issue warning information.

[0058] The first monitor continuously monitors the environment in front of the emergency stopping lane. When signs of falling rocks or landslides are detected, the control system activates an early warning program.

[0059] The first loudspeaker broadcasts a message to vehicles approaching from behind, advising them to reduce speed or move into the emergency lane. Simultaneously, the first signpost flashes an illuminated warning.

[0060] If the second monitor and the distributed ground sensors simultaneously detect a vehicle entering the barrier zone, the controller drives the first shaft to rotate, causing the trigger plate to unfold.

[0061] When a vehicle collides with the trigger plate, the barrier system is activated. The third pivot rotates to open the hinged panel on the barrier net storage box.

[0062] The rotator drives the traction rope to release the barrier net, while the first and second sliders slide rapidly along the guide rail, pulling the barrier net up and unfolding it to the preset blocking position.

[0063] The barrier net forms a flexible buffer structure, which can decelerate and brake the vehicle upon impact. If the vehicle fails to decelerate and breaks through the barrier net, the second-stage barrier device automatically activates and repeats the above process.

[0064] Example 2: Active interception procedure in the case of a multi-vehicle rear-end collision

[0065] This embodiment applies to scenarios involving chain-reaction rear-end collisions caused by emergency braking ahead on straight sections of highways.

[0066] The workflow is as follows:

[0067] The first monitor uses image recognition to monitor in real time whether there is congestion, brake clusters, or abnormal parking behavior in the driving lane.

[0068] Upon detecting an emergency, the first signboard emits a flashing warning light, and the first broadcaster announces, "Emergency situation ahead, please slow down and move to the right into the emergency lane."

[0069] If a vehicle from behind enters the emergency stopping lane, the second monitor on the second gantry, together with the ground sensor, determines whether the triggering conditions have been met.

[0070] If the conditions are met, the first rotating shaft will rotate to unfold the trigger plate, guiding the vehicles behind into the blocking area.

[0071] The barrier system begins operation, and the barrier net stored in the storage box is released outward with the movement of the rotator. The protective plate rotates with the third shaft, opening in conjunction with the opening and closing plate to ensure smooth release.

[0072] The barrier net absorbs kinetic energy after a vehicle impact, assisting in flexible deceleration, thereby reducing the severity of the accident and preventing more vehicles from rear-ending each other.

[0073] Example 3: Safety Barrier Procedure in Low Visibility Conditions at Night

[0074] This embodiment is applicable to nighttime driving environments on highways where visibility is low and drivers have insufficient reaction time.

[0075] The workflow is as follows:

[0076] The system activates night mode, and the first, second, and third monitors all switch to infrared imaging or low-light sensing mode.

[0077] If the monitor detects a sudden obstacle or accident vehicle, it immediately sends a signal to the control center, while simultaneously activating the sign lighting system and increasing the volume of the broadcast system.

[0078] After receiving the warning, the driver begins to decelerate. If the driver fails to decelerate successfully and enters the barrier zone, the system will detect the vehicle's entry status through ground sensors and a second monitor.

[0079] The triggering system drives the trigger plate to unfold based on the recognition result, guiding the vehicle into the buffer area.

[0080] Once the barrier system is activated, the barrier net quickly deploys to form a buffer and protection, assisting the vehicle to decelerate smoothly until it comes to a stop.

[0081] If the first layer of barrier netting fails due to impact, the system will automatically activate the backup barrier unit to ensure continuous safety protection.

[0082] Example 4: Deployment of a multi-level barrier system for disaster-prone road sections

[0083] It is suitable for complex road sections with multiple barrier units, such as tunnel entrances, bridge exits, or high slope areas.

[0084] The workflow is as follows:

[0085] Several independent barrier units are set up sequentially on the target road section. Each group includes a monitoring and early warning system, a triggering system, and a barrier system.

[0086] The front-end monitor first determines whether the first-level blocking system has been triggered. If the first blocking is successful, the subsequent systems will not be started.

[0087] If the first set of blocking systems fails to effectively slow down the vehicle, the second set will automatically deploy and begin blocking after receiving the boundary crossing signal from the third monitor.

[0088] Multi-level deployment ensures that even if a single-level system is damaged or fails, it can still achieve layer-by-layer buffering and braking, minimizing the risk of accidents.

[0089] Each system can be remotely managed through a unified control center, and has the capabilities of automatic judgment, sequential response, and independent operation.

[0090] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
