Description

Technical Field

[0001] This utility model relates to the field of traffic flow regulation system technology, and in particular to a tunnel intelligent adjustable speed bump system driven by traffic flow data. Background Technology

[0002] To improve driving safety within tunnels, prevent and alleviate traffic congestion, optimize the utilization efficiency of tunnel resources, and reduce traffic accidents, traffic flow control systems are typically installed in tunnels. These systems are high-tech traffic management systems designed to monitor and control traffic flow within the tunnel, ensuring its safe operation and efficient passage.

[0003] Existing traffic flow control systems only limit vehicle speeds by changing the speed limit value in tunnels in real time through dynamic speed limit signs. However, some vehicles still exceed the speed limit. Generally, speed bumps are used to slow down vehicles, but when it is possible to travel quickly in the tunnel, speed bumps reduce the driving experience. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a tunnel intelligent adjustable speed bump system driven by traffic flow data.

[0005] The technical solution of this utility model is: a tunnel intelligent adjustable speed bump system driven by traffic flow data, including a first vehicle detector fixedly installed at the tunnel entrance to count vehicles entering the tunnel, a second vehicle detector fixedly installed at the tunnel exit to count vehicles leaving the tunnel, a traffic light fixedly installed at the tunnel entrance, multiple dynamic speed limit signs fixedly installed inside the tunnel, and multiple adjustable speed bumps fixedly installed at the tunnel entrance.

[0006] The traffic flow regulation system calculates the number of vehicles inside the tunnel based on the first vehicle detector and the second vehicle detector, controls the traffic lights to issue a signal indicating whether vehicles can drive based on the number of vehicles inside the tunnel, adjusts the value on the dynamic speed limit sign in real time according to the traffic flow inside the tunnel, and simultaneously adjusts the curvature and height of the adjustable speed bump.

[0007] Optionally, the adjustable speed bump includes a base plate fixedly installed at the tunnel entrance, with a first arc-shaped plate slidably installed on both sides of the base plate, a second arc-shaped plate rotatably installed on one end of the first arc-shaped plate, and a top plate rotatably installed on both second arc-shaped plates, the top plate being slidably connected to the base plate.

[0008] Optionally, multiple telescopic rods are fixedly installed on the base plate, and the other end of each telescopic rod is fixedly connected to the top plate.

[0009] Optionally, the base plate is equipped with a distance adjustment mechanism for adjusting the distance between the two first arc-shaped plates.

[0010] Optionally, the adjusting mechanism includes a first connecting rod rotatably mounted on a first arc-shaped plate, and a synchronizing plate rotatably mounted on two first connecting rods located on the same side. The synchronizing plate is slidably connected to the base plate, and a force multiplier component and a power component are mounted on the base plate.

[0011] Optionally, the force multiplier includes a lever rotatably mounted on the base plate, the lever being slidably connected to the synchronization plate, and a second connecting rod rotatably mounted on one end of the lever, the second connecting rod being rotatably connected to the power component.

[0012] Optionally, the rotatable connection between the lever and the base plate is located near the synchronization plate.

[0013] Optionally, the power assembly includes a guide rod fixedly mounted on the base plate and a lead screw rotatably mounted on the base plate. A drive plate is slidably mounted on the guide rod and threadedly connected to the lead screw.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] This invention allows for adjustment of the speed bump's curvature based on traffic flow within the tunnel. This prevents low-curvature adjustable speed bumps from being insufficient to force all drivers to slow to the desired speed, and also prevents high-curvature adjustable speed bumps from causing bumps to vehicles.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1 to 4 As shown, this utility model proposes a tunnel intelligent adjustable speed bump system driven by traffic flow data. It includes a first vehicle detector 1 fixedly installed at the tunnel entrance to count vehicles entering the tunnel, and a second vehicle detector 2 fixedly installed at the tunnel exit to count vehicles exiting the tunnel. The first and second vehicle detectors 1 and 2 can detect vehicle presence, speed, traffic flow, and other information, providing real-time traffic data to the system. A traffic light 3 is fixedly installed at the tunnel entrance to control the flow of vehicles entering the tunnel and to regulate traffic flow and prevent congestion. Multiple dynamic speed limit signs 4 are fixedly installed inside the tunnel, displaying traffic information, warning information, and guidance information, such as lane closures, speed limits, and accident warnings. Multiple adjustable speed bumps 5 are fixedly installed at the tunnel entrance. The adjustable speed bumps 5 force vehicles to reduce speed before entering the tunnel, reducing potential traffic accidents caused by high-speed entry. Furthermore, tunnel entrances are often areas where vehicle speeds change significantly; the adjustable speed bumps 5 help vehicles decelerate smoothly, reducing rear-end collisions caused by insufficient reaction time due to excessive speed.

[0023] Furthermore, the traffic flow control system calculates the number of vehicles inside the tunnel based on the first vehicle detector 1 and the second vehicle detector 2. Based on this number, it controls the traffic lights 3 to signal whether vehicles can proceed. Simultaneously, it adjusts the speed limit values ​​on the dynamic speed limit signs 4 according to the traffic flow inside the tunnel, and also adjusts the curvature and height of the adjustable speed bumps 5. A low-curvature adjustable speed bump 5 may not be sufficient to force all drivers to slow down to the desired speed, while a high-curvature adjustable speed bump 5 can more effectively force vehicles to slow down. Therefore, the height of the adjustable speed bumps 5 can be adjusted in real time according to the traffic flow inside the tunnel to ensure safe passage for vehicles.

[0024] In this embodiment, the adjustable speed bump 5 includes a base plate 501 fixedly installed at the tunnel entrance. First arc-shaped plates 502 are slidably installed on both sides of the base plate 501. A second arc-shaped plate 503 is rotatably installed at one end of each first arc-shaped plate 502. A top plate 504 is rotatably installed on both second arc-shaped plates 503, and the top plate 504 is slidably connected to the base plate 501. When the top plate 504 rises, the speed bump achieves a better deceleration effect. When the top plate 504 falls, the adjustable speed bump 5 becomes flatter, reducing the bumpy feeling of vehicles passing over it. Multiple telescopic rods 505 are fixedly installed on the base plate 501, and the other end of each telescopic rod 505 is fixedly connected to the top plate 504. When the top plate 504 moves up and down, it will cause the second arc-shaped plates 503 to rotate, and the first arc-shaped plates 502 to move closer or further apart.

[0025] It is worth noting that an adjustment mechanism for adjusting the distance between the two first arc-shaped plates 502 is installed on the base plate 501. The adjustment mechanism includes a first connecting rod 506 rotatably mounted on the first arc-shaped plate 502, and a synchronization plate 507 rotatably mounted on the two first connecting rods 506 on the same side. The synchronization plate 507 is slidably connected to the base plate 501. A force multiplier assembly and a power assembly are installed on the base plate 501. The power assembly drives the force multiplier assembly to move, and the moving force multiplier assembly drives the synchronization plate 507 to move. When the synchronization plate 507 moves, it drives the first connecting rod 506 to rotate. The rotating first connecting rod 506 pushes the two first arc-shaped plates 502 to slide on the base plate 501, thereby adjusting the height of the adjustable speed bump 5.

[0026] Furthermore, the force multiplier component includes a lever 508 rotatably mounted on the base plate 501. The lever 508 is slidably connected to the synchronization plate 507. A second connecting rod 509 is rotatably mounted on one end of the lever 508, and the second connecting rod 509 is rotatably connected to the power component. When the power component drives the lever 508 to rotate, the rotating lever 508 can push the synchronization plate 507 to slide on the base plate 501, thereby driving the first connecting rod 506 to rotate. When the vehicle presses on the adjustable speed bump 5, the top plate 504 will be subjected to downward pressure, which will push the first arc-shaped plates 502 on both sides. The two first arc-shaped plates 502 jointly bear the pressure exerted by the vehicle on the adjustable speed bump 5, and the pushing force on the first arc-shaped plates 502 will act on the lever 508. Since the rotatable connection between the lever 508 and the base plate 501 is close to the synchronization plate 507. This results in a smaller force acting on the power assembly, thus effectively improving the load-bearing capacity of the adjustable speed bump 5. Furthermore, when adjusting the height of the adjustable speed bump 5, there is no vehicle pressure on it, so the power assembly can move the first arc plate 502 without overcoming significant resistance.

[0027] The power assembly includes a guide rod 510 fixedly mounted on the base plate 501, a lead screw 511 rotatably mounted on the base plate 501, a drive plate 512 slidably mounted on the guide rod 510, and a threaded connection between the drive plate 512 and the lead screw 511. A motor 513 is fixedly mounted on the base plate 501, and the output shaft of the motor 513 is coaxially and fixedly connected to the lead screw 511. Starting the motor 513 will drive the lead screw 511 to rotate, and the rotating lead screw 511 will drive the drive plate 512 to move. The drive plate 512 will drive the second connecting rod 509 to rotate, which will then push the lever 508 to rotate. The self-locking property between the lead screw 511 and the drive plate 512 can prevent the adjustable speed bump 5 from collapsing under pressure.

[0028] The working principle of this embodiment is as follows: starting the motor 513 will drive the lead screw 511 to rotate. The rotating lead screw 511 will drive the drive plate 512 to move. The drive plate 512 will drive the second connecting rod 509 to rotate, which will push the lever 508 to rotate. The self-locking between the lead screw 511 and the drive plate 512 can prevent the adjustable speed bump 5 from collapsing under pressure. The rotating lever 508 can push the synchronous plate 507 to slide on the base plate 501, thereby driving the first connecting rod 506 to rotate. The rotating first connecting rod 506 can push the first arc-shaped plates 502 on both sides to slide on the base plate 501, thereby adjusting the height of the adjustable speed bump 5.

[0029] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
