Description

Technical Field

[0001] The present invention belongs to the technical field of traffic safety and relates to an intelligent safety blocking device for a highway and an implementation method thereof. Background Art

[0002] With the continuous expansion of the expressway network and the increasing speeds of vehicles, while ensuring traffic efficiency, expressways also face increasingly severe challenges in ensuring safety. This is particularly true in areas with complex terrain, such as mountainous and hilly areas or at the junction of bridges and tunnels. Sudden natural disasters such as rockfalls on high slopes, landslides, mudslides, and roadbed collapses are frequent. Furthermore, major traffic accidents on expressways, such as multi-vehicle rear-end collisions, rollovers, tire blowouts, and spontaneous combustion, are also on the rise.

[0003] When such emergencies occur, drivers of following vehicles often struggle to react effectively due to the high speeds of vehicles traveling on highways. They often resort to emergency braking or rapid lane changes to avoid them. However, due to short reaction times, limited visibility, and complex road conditions, this human-induced emergency response can easily lead to secondary accidents or even chain collisions, posing a serious threat to life and property. Existing highway infrastructure typically relies solely on fixed warning signs and monitoring systems, with limited dynamic response capabilities to emergencies and a lack of a comprehensive intelligent proactive interception system.

[0004] Although some highways have deployed Intelligent Transportation Systems (ITS), which collect and transmit information through video surveillance, dynamic guidance signs, and broadcast systems, these systems primarily focus on providing information and guidance, lacking the ability to physically intercept or flexibly buffer vehicles traveling at high speeds. In particular, there is a lack of active safety protection technology that can effectively intervene and reduce vehicle speed when the driver is unable to brake or actively control the vehicle in a timely manner.

[0005] Therefore, there is an urgent need for an intelligent highway safety interception technology system that integrates real-time monitoring, intelligent judgment, automatic triggering, and physical buffering. This system can not only issue timely and effective warnings in emergency situations, but also automatically deploy interception devices when necessary to physically slow down and brake vehicles, effectively avoiding or reducing the severity of traffic accidents. The proposal and implementation of this system will fill a critical gap in existing highway traffic safety technology. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to provide an intelligent highway safety blocking device and implementation method. During long-term use, highway subgrade structural stability and durability continue to decline under the influence of vehicle loads, rain, wind, and other factors. High-slope sections are prone to disasters such as rockfall, landslides, mudslides, and subgrade collapses, posing serious challenges to highway driving safety and traffic efficiency. When a natural disaster or traffic accident occurs ahead of a vehicle, and the vehicle itself is unable to quickly and safely brake to a stop, the present invention provides an intelligent highway safety blocking device and implementation method that can effectively assist high-speed vehicles in emergency braking, providing safety protection for highway vehicles.

[0007] In order to achieve the above object, the present invention provides the following technical solutions:

[0008] An intelligent safety blocking device for a highway, comprising:

[0009] Monitoring and warning systems, triggering systems and arresting systems;

[0010] in,

[0011] The monitoring and early warning system includes:

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

[0013] The trigger system comprises:

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

[0015] The arresting system comprises:

[0016] A column is arranged outside the median strip and the shoulder, and the column is provided with a guide rail, a slidable first slider and a second slider, the sliders are respectively connected to the first arresting cable and the second arresting cable, the arresting cable passes through the arresting net, and the arresting net is reinforced by a transverse cable, the transverse cable is provided with a lock, the lock is connected to the second rotating shaft through a traction rope, the second rotating shaft is driven to rotate by a rotator to control the release and retraction of the arresting net, the arresting net is stored in a storage box, the top of the storage box is connected to the protective plate and the opening and closing plate through a third rotating shaft, and 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 arresting system to perform long-distance real-time monitoring and early warning of key road sections.

[0018] Furthermore, the second monitor in the trigger system is combined with the distributed sensor arranged under the emergency stop strip to determine whether there is a vehicle entering the barrier strip passage area, which is used to trigger the trigger plate to open automatically.

[0019] Furthermore, the first slider and the second slider slide along the guide rail to unfold or retract the barrier net. The barrier net is stored in the storage box in a non-working state. The storage box is closed or opened by driving the opening and closing plate through the third rotating shaft.

[0020] Furthermore, a barrier net prompt sign is provided on the surface of the column to indicate whether the vehicle can enter the emergency parking lane to use the barrier function.

[0021] A method for realizing intelligent safety blocking on a highway includes the following steps:

[0022] S1: The first monitor of the monitoring and warning system monitors the road driving environment in real time. If a vehicle is detected entering the emergency parking lane, the first broadcaster and the first signboard 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 zone, the first shaft in the trigger system drives the trigger plate to open, and the second broadcaster and the second signboard issue a warning message;

[0024] S3: If the vehicle hits the trigger plate, the arresting system is activated, and the third shaft drives the opening and closing plate to open, releasing the arresting net;

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

[0026] S5: If the vehicle successfully hits the barrier and brakes, it waits for on-site rescue; if the braking is unsuccessful, the third monitor will identify it and trigger the next level of arresting system to repeat S3 to S5.

[0027] Furthermore, in S2, if the vehicle exits the barrier zone and does not collide with the trigger plate, the system automatically cancels the activation instruction and returns to the standby state.

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

[0029] Furthermore, the first to third monitors all have night vision functions and can coordinate with broadcasters and signboards to provide early warning prompts at night.

[0030] The beneficial effects of the present invention are:

[0031] The present invention provides an intelligent highway safety arresting device and implementation method, which can effectively address the technical deficiencies of existing highway emergency response technologies, improve the safe braking capabilities of vehicles in special circumstances, and enhance traffic safety in high-speed driving environments. Compared with existing technologies, the present invention has the following beneficial effects:

[0032] First, the present invention conducts dynamic environmental monitoring of key sections of highways through a monitoring and early warning system, which can identify the risks of sudden natural disasters or traffic accidents in the first place, provide early warning to vehicles behind, and improve the efficiency of emergency response to sudden incidents.

[0033] Secondly, the trigger system provided in the present invention can be linked with the vehicle path and environmental perception results. When it is detected that a vehicle enters the barrier zone, the trigger device is automatically released to guide the vehicle into a dedicated buffer zone to prepare for subsequent blocking actions and reduce the delay of system response.

[0034] Thirdly, by employing a multi-level deployable flexible barrier net structure, the present invention proactively intervenes and physically decelerates the vehicle if it cannot safely stop through self-braking, reducing the impact of the collision and preventing the accident from escalating. Furthermore, the system is resilient and scalable, supporting the deployment of subsequent barrier systems even if the first level of barrier fails, thus improving overall fault tolerance and safety assurance levels.

[0035] In addition, the present invention adopts a modular design, and the various systems work together but are relatively independent, which facilitates engineering deployment and maintenance. It can be applied to a variety of terrain and road conditions, and is particularly suitable for deployment on roads where disasters are frequent, traffic accidents are frequent, or visibility is low.

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

[0050] See also Figures 1 to 7 The present invention aims to provide an intelligent highway safety blocking device and implementation method to assist high-speed vehicles in emergency braking, providing safety for highway vehicles. The intelligent highway safety blocking device and implementation method include a monitoring and early warning system, a triggering system, and a blocking system and implementation method.

[0051] The monitoring and early warning system 2 includes a No. 1 gantry 2-1 with two columns, one buried outside the median strip 8 and the other outside the shoulder 5 of the road 9. A No. 1 broadcaster 2-2 is mounted on the top of the No. 1 gantry 2-1 column, and a No. 1 signboard 2-3 and a No. 1 monitor 2-4 are mounted on the crossbar of the No. 1 gantry 2-1. The No. 1 signboard 2-3 uses its own lighting to achieve night vision. In emergencies, it can flash to remind oncoming vehicles to decelerate, avoid, or stop. The No. 1 broadcaster 2-2 and the No. 1 signboard 2-3 use voice announcements and prompts to remind the following vehicle 1 that it is generally prohibited to enter the barrier lane 6. In the event of an emergency requiring an emergency stop, it may temporarily enter. The No. 1 monitor 2-4 can dynamically monitor the driving environment in front of the barrier device. Combined with the monitoring information of the No. 3 monitor 4-13 of the barrier system 4, it can provide long-distance, real-time monitoring and early warning of key road sections.

[0052] The trigger system 3 includes two columns, a No. 2 gantry 3-3, which is respectively buried in the central dividing strip 8 of the road 9 and outside the shoulder 5. 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, and the No. 2 signboard 3-5 and the No. 2 monitor 3-6 are installed on the cross bar of the No. 2 gantry 3-3. Among them, under normal circumstances, the trigger plate 3-2 is folded and stored on the column of the No. 2 gantry 3-3. When the No. 2 monitor 3-6 and the distributed sensors under the emergency stop strip 6 simultaneously detect that there is a vehicle 1 passing through the barrier strip passage area, the No. 1 shaft 3-1 rotates to open the trigger plate 3-2. After the trigger plate 3-2 is opened, it occupies the emergency stop strip 6 but does not encroach on the space of the carriageway 7. The No. 2 signboard 3-5 can realize the night vision function through its own lighting. In an emergency, it can flash to remind the rear vehicle to slow down, avoid or stop urgently. The No. 2 broadcaster 3-4 and the No. 2 signboard 3-5 remind the rear vehicle 1 through voice broadcast and prompts respectively. Under normal circumstances, it is prohibited to enter the barrier strip of the emergency stop strip 6. When encountering an emergency situation and requiring auxiliary emergency parking, you can temporarily enter and drive to collide with the trigger plate 3-2 to activate the arresting system 4.

[0053] The arresting system 4 comprises two columns 4-3 respectively buried in the middle dividing strip 8 of the road 9 and outside the shoulder 5. A No. 3 monitor 4-13 is installed on the top of the column 4-3. A guide rail 4-2 is provided inside the column 4-3. A No. 1 slider 4-1 and a No. 2 slider 4-4 which can slide up and down on the guide rail 4-2 are connected to the ends of the No. 1 arresting cable 4-6 and the No. 2 arresting cable 4-12 respectively. The No. 1 arresting cable 4-6, the No. 2 arresting cable 4-12 and the cross cable 4-8 respectively pass through the arresting cable. Net 4-5 and transverse cables 4-8 are equipped with locks 4-7. The bottom end of lock 4-7 is connected to the second rotating shaft 4-11 via a traction rope 4-10. Rotator 4-9 rotates to drive the traction rope 4-10 to retract and deploy the barrier net 4-5. The barrier net 4-5 is typically stored in a storage box 10. A third rotating shaft 12 at the top of the storage box 10 is connected to a protective plate 11 and a retractable plate 13. The third rotating shaft 12 rotates to open and close the retractable plate 13. A barrier net sign is placed on the surface of the column 4-3. A third monitoring device 4-13 dynamically monitors the driving environment near the barrier system 4.

[0054] Example 1: Deployment process of intelligent safety blocking system for sudden rockfall sections

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

[0056] The workflow is as follows:

[0057] A first gantry and a second gantry are set on both sides of the target road section. A first monitor, a first broadcaster and a first signboard are installed on the first gantry for real-time monitoring of road conditions and issuing warning information.

[0058] The first monitor continuously monitors the environment in the area ahead of the emergency stop strip. If it detects signs of rockfall or landslides on the road, the control system initiates an early warning program.

[0059] The first broadcaster broadcasts a message to the vehicles behind by voice, prompting them to slow down or drive into the emergency lane. The first signboard flashes and lights up at the same time.

[0060] If the second monitor and the distributed ground sensor simultaneously detect that a vehicle enters the barrier strip passage area, the controller drives the first rotating shaft to rotate to deploy the trigger plate.

[0061] When a vehicle collides with the trigger plate, the arresting system is activated. The third shaft rotates to open the opening and closing plate on the arresting net storage box.

[0062] The rotator drives the traction rope to release the barrier net, and at the same time the first slider and the second slider slide quickly along the guide rail to pull the barrier net up and unfold it to the preset barrier position.

[0063] The barrier net forms a flexible buffer structure that can decelerate and brake the vehicle after impact. If the vehicle fails to decelerate and break through the barrier net, the second-level barrier device will automatically activate and repeat the above process.

[0064] Example 2: Active Interception Process in a Multi-Vehicle Rear-End Collision Accident

[0065] This embodiment is applicable to the risk scenario of a chain rear-end collision caused by emergency braking in front of the vehicle on a straight section of a highway.

[0066] The workflow is as follows:

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

[0068] After detecting an emergency, the first signboard emits a flashing warning light, and the first broadcaster broadcasts voice content such as "Emergency ahead, please slow down, drive to the right and enter the safety zone."

[0069] If a rear vehicle enters the emergency parking lane, the second monitor on the second gantry and the ground sensor jointly determine whether the triggering conditions are met.

[0070] If the conditions are met, the first shaft rotates to deploy the trigger plate, guiding the rear vehicle into the blocking area.

[0071] The arresting system begins operating, and the arresting net stored in the storage box is released outwards as the rotator moves. The protective plate rotates along the third axis and opens in conjunction with the opening and closing plate to ensure smooth release.

[0072] The barrier absorbs kinetic energy after the vehicle impacts, helping to achieve flexible deceleration, thereby reducing the severity of the accident and preventing more vehicles from rear-ending each other.

[0073] Example 3: Safe arrest process under low visibility conditions at night

[0074] This embodiment is suitable for driving on a highway at night, where visibility is low and the driver's reaction time is insufficient.

[0075] The workflow is as follows:

[0076] The system starts the night operation mode, and the first monitor, the second monitor and the third monitor are all switched to infrared imaging or low light sensitivity mode.

[0077] If the monitor identifies a sudden obstacle or an accident vehicle, it will immediately feedback a signal to the control center, activate the sign lighting system and increase the volume of the broadcaster.

[0078] After receiving the warning, the driver starts to slow down. If he fails to slow down and enters the barrier, the system will detect the vehicle's entry status through ground sensors and a second monitor.

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

[0080] After the arresting system is activated, the arresting net is quickly deployed to form a buffer protection, helping the vehicle to slow down smoothly until it stops.

[0081] If the first layer of barrier net 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 sections

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

[0084] The workflow is as follows:

[0085] Several groups of independent blocking units are set up in sequence on the target road section, each group includes a monitoring and early warning system, a triggering system and a blocking system.

[0086] The front-end monitor will first determine whether to trigger the first-level arrest system. If the first arrest is successful, the subsequent system will not start.

[0087] If the first set of arresting systems fails to effectively slow down the vehicle, the second set will automatically deploy upon receiving the out-of-bounds signal from the third monitor to carry out the arrest.

[0088] Multi-stage deployment ensures that even if a single-stage system is damaged or fails, layer-by-layer buffer braking can still be achieved, 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 limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions, which should all be included in the scope of the claims of the present invention.
