Description

Technical Field

[0001] The present invention relates to the field of road safety technology, and in particular to an intelligent anti-collision guardrail, system and method suitable for long downhill slopes on mountain roads. Background Art

[0002] In recent years, low-grade roads in mountainous areas, especially long downhill sections, have experienced frequent traffic accidents due to their low road grade, poor horizontal and vertical indicators, and serious road damage. In minor cases, the car is damaged, causing traffic jams; in serious cases, the car overturns, runs off the road and rolls down the slope, causing major casualties. This situation is common on mountain roads.

[0003] The main reasons for this situation are: 1) Mountain roads are restricted by terrain conditions, with poor horizontal and vertical indicators and low design speeds, and passing vehicles often exceed the design speeds; 2) The roads are narrow and visibility is limited, making it impossible to judge road conditions in advance, especially on bends where it is very easy to run off the road; 3) Mountain roads are generally long and winding downhill, and large trucks have great inertia. When encountering rainy or snowy weather, the braking effect is poor and they are forced to run off the road; 4) The road surface width of low-grade roads is insufficient.

[0004] In order to solve the above situation, guardrails are generally installed on one side of the mountain road.

[0005] Current guardrails typically consist of upright posts and guardrail panels above them, constructed from steel plates. These panels, being rigid materials, are also rigidly connected. If a car loses control and collides with the guardrail, the guardrail can prevent the car from running off the road. However, practice has shown that these guardrail panels lack a cushioning function. Under the powerful impact of a high-speed, out-of-control car, they often break, causing the car to veer off the road, resulting in fatalities. Cracked guardrails can cause more serious injuries and fail to effectively prevent the car from running off the road. Furthermore, guardrails made from steel plates can become porous, losing their resistance to pressure and collisions, resulting in a short service life.

[0006] In addition, the existing guardrails are set at a high height and are evenly distributed along one side of the mountain road. When the road surface is relatively narrow, it is easy to cause a greater sense of oppression to the driver, thereby affecting the driver's driving safety. Summary of the Invention

[0007] The purpose of the present invention is to provide an intelligent anti-collision guardrail, system and method suitable for long and downhill mountain roads. It aims to solve the technical problems in the prior art that the guardrail plate has no buffering function, which will aggravate the occurrence and loss of accidents under the strong impact of moving vehicles and improve the service life of the anti-collision device.

[0053] [Example]

[0054] like Figure 1As shown, an intelligent anti-collision guardrail suitable for long and downhill mountain roads includes a connecting column 1, a guardrail plate 2 and a flexible protective net 3; the connecting column 1 is buried at the side of the road where a guardrail is needed, and a slide rail 11 is provided on the surface of the connecting column 1; the guardrail plate 2 is located between adjacent connecting columns 1, and the two ends of the guardrail plate 2 are respectively connected to the slide rails 11 on the surface of the connecting column; the guardrail plate 2 is divided into an upper guardrail plate 21, a middle guardrail plate 22 and a lower guardrail plate 23, and the width of the upper guardrail plate 21 and the lower guardrail plate 23 are equal, and the width of the middle guardrail plate 22 is greater than the width of the upper guardrail plate 21 or the lower guardrail plate 23; the flexible protective net 3 is arranged between the upper guardrail plate 21 and the lower guardrail plate 23, and when the anti-collision device is not started, the flexible protective net 3 is in a telescopic state.

[0055] Among them, the connecting columns are set on the outside of the highway, and one is set every 10 meters; the length of the middle guardrail is equal to the distance between adjacent connecting columns; when the anti-collision device is not activated, the guardrail of the entire anti-collision device is only 1 to 1.5 meters high, which will not affect the driving on mountain roads, and there is no driving pressure caused by the use of high guardrails, thereby improving driving safety.

[0056] Furthermore, a slider is provided on the upper guardrail plate 21 , which is installed on the slide rail 11 and is used for the upper guardrail plate 21 to slide along the slide rail 11 ; and mutually cooperating limiting components are also provided on the connecting column 1 and the upper guardrail plate 21 .

[0057] Furthermore, the limiting component is to set a card point at the upper end of the connecting column 1, and set convex points on the left and right ends of the upper guardrail plate 21 respectively; the limiting component is used to fix the position of the upper guardrail plate 21 after the anti-collision device is activated.

[0058] like Figure 2 As shown, the anti-collision device adopts a liftable upper guardrail plate. Since the flexible protective net is in a folded state when the anti-collision device is not activated, the service life of the anti-collision device can be increased and the use cost of the anti-collision device can be reduced. At the same time, mutually cooperating limiting components are provided on the connecting column and the upper guardrail plate, which can effectively prevent the upper guardrail plate from sliding out of the connecting column when sliding, thereby affecting the working efficiency of the anti-collision device.

[0059] The limiting member in this solution can also be fixed by a snap-fit method or a spring.

[0060] like Figure 3As shown, when the anti-collision device is activated, the upper guardrail slides along the direction of the slide rail on the surface of the connecting column, and the flexible protective net is opened. The flexible protective net has good buffering force, rebound force, plasticity and impact resistance, and can effectively prevent and reduce the driving vehicle from running off the road, overturning or other safety accidents under strong impact; at the same time, the present invention adopts a liftable upper guardrail, which can effectively avoid the guardrail height being too high to increase the driving oppression on the mountain road surface which is not wide, thereby affecting driving safety.

[0061] Furthermore, the middle guardrail plate 22 and the lower guardrail plate 23 are fixedly connected to the slide rail 11, and the lower guardrail plate 23 is 0.3m away from the ground; when the anti-collision device is not activated, the upper guardrail plate 21 is 0.8m away from the ground; after the anti-collision device is activated, the upper guardrail plate 21 is 0.8~1m away from the ground.

[0062] Furthermore, the height of the connecting column 1 is 5m, and the connecting column 1 is a box-shaped section with internal ribs.

[0063] Furthermore, the middle guardrail plate 22 is a corrugated steel plate, and the middle guardrail plate 22 is 0.5 m wider than the upper guardrail plate 21 or the lower guardrail plate 23 .

[0064] Furthermore, the anti-collision device also includes a control device, an infrared projector 4 and an intelligent alarm device 5, which are installed between the upper guardrail plate 21 and the lower guardrail plate 23; the control device, the infrared projector 4 and the intelligent alarm device 5 are electrically connected.

[0065] The present invention also provides an intelligent anti-collision system suitable for long downhill slopes on mountain roads, comprising an anti-collision device and a server;

[0066] The infrared projector 4 is used to project infrared rays onto the middle guardrail plate 22; the server includes: a data processing module for presetting and storing the contact range value between the moving vehicle and the protruding middle guardrail plate; a judgment module for judging whether the contact area between the moving vehicle and the protruding middle guardrail plate exceeds the preset value in the data processing module. If the contact area between the moving vehicle and the protruding middle guardrail plate exceeds the preset value in the data processing module, the judgment module sends a control instruction to the control device and the intelligent alarm device 5; the control device is used to control the upper guardrail plate to slide along the direction of the slide rail and open the flexible protective net; the intelligent alarm device 5 is used to send alarm information to relevant units and issue an alarm to remind passing vehicles.

[0067] Furthermore, the judgment module includes: a first judgment module for judging whether the moving vehicle is in contact with the protruding middle guardrail plate, and if the moving vehicle is in contact with the protruding middle guardrail plate, a second judgment is performed; a second judgment module is used to judge whether the deformation of the middle guardrail plate exceeds 0.5m or whether the moving vehicle directly damages the surface of the upper guardrail plate and the lower guardrail plate or the moving vehicle touches the infrared ray projected by the infrared projector. If the deformation of the middle guardrail plate exceeds 0.5m or the moving vehicle directly damages the surface of the upper guardrail plate and the lower guardrail plate or the moving vehicle touches the infrared ray projected by the infrared projector, the second judgment module will send a control instruction to the control device and the intelligent alarm device 5.

[0068] The working principle of the present invention is:

[0069] S1: Install an anti-collision device on the outside of the mountain road. When the anti-collision device is not activated, the flexible protective net is in a telescoping state;

[0070] S2: Using the infrared projector 4 to project infrared rays onto the middle guardrail plate 22;

[0071] S3: Presetting a contact range value between the moving vehicle and the protruding middle guardrail in the data processing module;

[0072] S4: Using the judgment module to judge whether the contact area between the moving vehicle and the protruding middle guardrail plate exceeds the preset value in the data processing module, if the contact area between the moving vehicle and the protruding middle guardrail plate exceeds the preset value in the data processing module, sending a control instruction to the control device and the intelligent alarm device;

[0073] S5: After receiving the control instruction sent by the judgment module, the control device controls the upper guardrail to slide along the slide rail and open the flexible protective net;

[0074] S6: After receiving the control instruction sent by the judgment module, the intelligent alarm device 5 sends alarm information to relevant units and sounds an alarm to remind passing vehicles.
