Description

Technical Field

[0001] The present invention relates to the field of tunnel outline lights, in particular to a tunnel outline light control system and a tunnel outline light for traffic warning. Background Art

[0002] When a car accident occurs in a tunnel, the narrow roads in the tunnel can easily cause congestion for subsequent vehicles. Moreover, if the car accident occurs when entering the tunnel, the rapid change in light brightness makes it impossible for subsequent vehicles to promptly discover the car accident at the tunnel entrance, which can result in rear-end collisions. Existing tunnel warning lights have low brightness and a small warning area, and the brightness inside the tunnel is low, making it difficult to observe the warning lights in time. Therefore, a warning light with a more eye-catching warning effect is needed. Summary of the Invention

[0003] The present invention provides a tunnel outline light control system for traffic warning and a tunnel outline light, which overcome the deficiencies described in the background art.

[0004] The technical solution adopted by the present invention to solve its technical problem is:

[0005] A tunnel outline light for traffic warning, wherein the tunnel outline lights are arranged equidistantly along the length of the tunnel, and the tunnel outline light comprises a fixing plate, a lamp housing, and a warning mechanism mounted at the lower end of the lamp housing, wherein the lamp housing is fixed to the tunnel body via the fixing plate;

[0006] A plurality of lamp beads are arranged on both sides of the lamp housing, and the lamp beads are connected in series and emit light when energized. A motor 1 for retracting and extending the warning mechanism is also provided in the lamp housing. The warning mechanism is composed of a plurality of warning plates, and every two adjacent warning plates are connected by a rotating shaft, and the swing directions of the two adjacent warning plates are opposite. A traction rope is wound around the output shaft of the motor 1, and the traction rope passes through all the warning plates in sequence and is connected to the surface of the lowest warning plate. When the motor 1 rotates the output shaft to reel in the traction rope, each warning plate is driven to swing upward and gather from bottom to top.

[0007] All warning boards are provided with reflective sheets on their surfaces. When the motor lowers the warning boards, the reflective sheets on all warning boards face the same direction.

[0008] A preferred technical solution is that a transmission structure is provided on the side of the lamp housing, and the warning mechanism is connected to the lamp housing through the transmission structure. The transmission structure includes a power end and a movable end arranged on the surface of the lamp housing. The movable end is connected to the warning mechanism, and the movable end is arranged near the central axis of the warning mechanism. The lamp housing is arranged outside the movable end through a fixed shaft sleeve, and the movable end protrudes from the left and right sides of the fixed shaft respectively. When the power end is working, the power end alternately pushes the movable end protruding from the surfaces on both sides of the fixed shaft, and drives the warning mechanism to swing through the movable end.

[0009] In a preferred technical solution, the transmission structure includes a second motor and a push rod disposed on the surface of the lamp housing. The push rods are symmetrically arranged, and each push rod includes a gear rod and an eccentric rod. The eccentric rod is connected to the side of the gear rod and is disposed offset from the center of the gear rod. The two eccentric rods are offset in opposite directions.

[0010] The eccentric rods in the two push rods are set away from each other, and the adjacent surfaces of the two gear rods are provided with tooth grooves. A driving gear disc engaged with the gear rod is provided on the output shaft of the second motor to drive the two gear rods to rotate through the second motor.

[0011] A preferred technical solution, the movable end includes a card bead and movable rocker arms symmetrically arranged on both sides of the card bead, the two movable rocker arms protrude from the ends of both sides of the fixed shaft and are connected to the surface of the warning mechanism, a spherical cavity and a conical cavity are provided on the inner side of the fixed shaft, the conical cavity is symmetrically arranged on the left and right sides of the spherical cavity, the movable rocker arm passes through the conical cavity and extends out of the end of the fixed shaft, and a movable gap is provided between the movable rocker arm and the conical cavity, and the movable gap is filled with an airbag cushion.

[0012] A control system for traffic warning tunnel outline lights, applicable to such traffic warning tunnel outline lights, is characterized in that the control system includes tunnel outline lights installed inside the tunnel body, a camera, and a control module. The tunnel outline lights are arranged equidistantly along the length of the tunnel body. The control module forms a signal connection with all tunnel outline lights to monitor moving vehicles via the camera and manually identify traffic accidents during driving. When a traffic accident occurs, the control module controls the tunnel outline lights above the corresponding lane to illuminate.

[0013] When a car accident occurs, the control module controls the tunnel outline lights above the corresponding lane to light up, and the two adjacent tunnel outline lights in front and behind flash alternately.

[0014] A preferred technical solution is to set cameras above each lane in the tunnel body. Each camera and its adjacent monitoring area form a monitoring area. There is an intersecting area between the left and right adjacent monitoring areas on the two lanes. Vertically arranged tunnel contour lights are set in the intersecting area. When a traffic accident occurs in the monitoring area, all tunnel contour lights in the intersecting area can be controlled.

[0015] In a preferred technical solution, when a traffic accident occurs in a certain monitoring area and the tunnel marker lights above the corresponding lane are illuminated, all tunnel marker lights in the lane will flash alternately from near to far, with the monitoring area where the traffic accident occurred as the center, with the frequency interval gradually increasing, and the frequency of increase is n+0.5s;

[0016] Wherein, n is the flashing frequency interval time of the monitoring area where the traffic accident occurred, and the flashing frequency interval time is 0.3s.

[0017] Compared with the existing technology, this technical solution has the following advantages:

[0018] The present invention effectively solves the problems of low brightness, small warning area and difficulty in timely observation of existing tunnel warning lights in dark tunnels by decentralizing the warning mechanism. First, the reflective monitoring area formed after the warning mechanism is deployed is large, which can significantly improve the warning effect on following vehicles. The design of the reflective sheet makes it possible to clearly see the reflective monitoring area in a dark tunnel even if the vehicle lights are weak, thereby detecting accidents or other abnormal situations ahead in advance and avoiding secondary accidents such as rear-end collisions. Secondly, through the precise control of motor one, the deployment and retraction process of the warning mechanism is fast and stable, and the warning function can be quickly activated in an emergency. At the same time, the warning mechanism can be retracted under normal circumstances without affecting the normal traffic order in the tunnel. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] like Figures 1 to 9 As shown, the present invention provides a traffic warning tunnel marker light, comprising a tunnel marker light 100 mounted inside a tunnel body 200. The tunnel marker lights 100 are arranged equidistantly along the length of the tunnel body 200. The tunnel marker light 100 includes a fixing plate 1, a lamp housing 2, and a warning mechanism 3 mounted at the lower end of the lamp housing 2. The lamp housing 2 is fixed within the tunnel body 200 via the fixing plate 1.

[0037] A plurality of lamp beads 21 are arranged on both sides of the lamp housing 2, and the lamp beads 21 are connected in series and emit light when energized. A motor 22 for retracting and extending the warning mechanism 3 is also provided in the lamp housing 2. The warning mechanism 3 is composed of a plurality of warning plates, and every two adjacent warning plates are connected by a rotating shaft, and the swing directions of the two adjacent warning plates are opposite. A traction rope 23 is wound around the output shaft of the motor 22, and the traction rope 23 passes through all the warning plates in sequence and is connected to the surface of the lowest warning plate. When the motor 22 rotates the output shaft to reel in the traction rope 23, each warning plate is driven to swing upward and gather from bottom to top.

[0038] All warning plates are provided with reflective sheets on their surfaces. When the motor 22 lowers the warning plates, the reflective sheets on all warning plates face the same direction.

[0039] In the tunnel contour light of the present invention, the lowering process of the warning mechanism 3 is achieved through the precise control of the motor 1 22. When an accident or other situation requiring warning occurs in the tunnel, the control system will send a command to the motor 1 22 to start the rotation of its output shaft. At this time, the output shaft of the motor 1 22 will release the traction rope 23 wrapped around it. The traction rope 23 passes through all the warning plates in turn, and as the traction rope 23 is gradually released, the warning plates are unfolded from top to bottom in turn. Since adjacent warning plates are connected by a rotating shaft and swing in opposite directions, this design enables the warning plates to form an orderly unfolding state during the unfolding process, similar to the unfolding method of an accordion. Finally, all the warning plates are fully unfolded, and the reflective sheets on their surfaces face the same direction, forming a large-area reflective monitoring area.

[0040] The present invention effectively solves the problems of low brightness, small warning area and difficulty in timely observation of existing tunnel warning lights in dark tunnels by decentralizing the warning mechanism 3. First, the reflective monitoring area formed after the warning mechanism 3 is deployed is large, which can significantly improve the warning effect on following vehicles. The design of the reflective sheet makes it possible to clearly see the reflective monitoring area in a dark tunnel even if the vehicle lights are weak, thereby detecting accidents or other abnormal situations ahead in advance and avoiding secondary accidents such as rear-end collisions. Secondly, through the precise control of the motor 22, the deployment and folding process of the warning mechanism 3 is fast and stable, and the warning function can be quickly activated in an emergency. At the same time, the warning mechanism 3 can be folded under normal circumstances without affecting the normal traffic order in the tunnel. This automated control method not only improves the safety of the tunnel, but also reduces the need for manual intervention and improves management efficiency.

[0041] Traditional tunnel warning lights typically use a simple flashing or constant-on mode, resulting in a small warning area. Furthermore, in dimly lit tunnels, the light visibility is poor, making it difficult for following vehicles to pay sufficient attention. This is especially true at tunnel entrances where light levels change rapidly, where drivers can easily overlook the warning light. The present invention creates a large reflective monitoring area by decentralizing the warning mechanism 3. The reflective sheet design allows the monitoring area to produce a strong reflective effect when illuminated by vehicle lights, making it clearly visible to drivers even in dimly lit tunnels. This large reflective monitoring area is more eye-catching than a simple flashing or constant-on mode and can more effectively alert drivers to abnormal conditions ahead.

[0042] Furthermore, a transmission structure is provided on the side of the lamp housing 2, and the warning mechanism 3 is connected to the lamp housing 2 through the transmission structure. The transmission structure includes a power end and a movable end arranged on the surface of the lamp housing 2. The movable end is connected to the warning mechanism 3, and the movable end is arranged near the central axis of the warning mechanism 3. The lamp housing 2 is sleeved on the outside of the movable end through a fixed shaft 24, and the movable end protrudes from the left and right sides of the fixed shaft 24 respectively. When the power end is working, the power end alternately pushes the movable end protruding from the surfaces on both sides of the fixed shaft 24, and drives the warning mechanism 3 to swing through the movable end.

[0043] The transmission structure includes a second motor 25 and a push rod 26 provided on the surface of the lamp housing 2. The push rods 26 are symmetrically arranged. The two push rods 26 each include a gear rod 261 and an eccentric rod 262. The eccentric rod 262 is connected to the side of the gear rod 261 and is offset from the center of the gear rod 261. The two eccentric rods 262 are offset in opposite directions.

[0044] The eccentric rods 262 in the two push rods 26 are arranged away from each other, and the adjacent surfaces of the two gear rods 261 are provided with tooth grooves. The output shaft of the second motor 25 is provided with a driving gear plate 251 that meshes with the gear rods 261, so that the two gear rods 261 are driven to rotate by the second motor 25;

[0045] As can be seen above, the design of the eccentric rod 262 offset from the center of the circle enables it to generate a thrust with a continuously changing direction during rotation. This change in direction of thrust more effectively propels the movable end, causing it to swing more significantly. Because the eccentric rod 262 deviates in opposite directions, the two push rods 26 can cooperate with each other during operation, generating a larger swing amplitude. This design makes the swing of the warning mechanism 3 more noticeable.

[0046] In addition, the movable end includes a card bead 32 and a movable rocker 31 symmetrically arranged on both sides of the card bead 32. The two movable rocker 31 protrude from the ends of both sides of the fixed shaft 24 and are connected to the surface of the warning mechanism 3. A spherical cavity and a conical cavity are provided on the inner side of the fixed shaft 24. The conical cavity is symmetrically arranged on the left and right sides of the spherical cavity. The movable rocker 31 passes through the conical cavity and extends out of the end of the fixed shaft 24. A movable gap is provided between the movable rocker 31 and the conical cavity, and the airbag cushion 33 is filled in the movable gap.

[0047] The design of the movable rocker arm 31 passing through the conical cavity enables the warning mechanism 3 to obtain a more flexible movement space during the swinging process. The special shape of the conical cavity provides a guide for the movable rocker arm 31, ensuring that it can move smoothly along the preset trajectory when swinging, avoiding jamming or irregular swinging due to structural limitations. This smooth swinging can enable the reflective sheet on the warning mechanism 3 to reflect light in a more stable manner, thereby improving the clarity and stability of the warning signal and enhancing the warning effect on passing vehicles. In addition, in the complex traffic environment of the tunnel, the vibration of the vehicle and the impact of the airflow may have a certain impact on the warning mechanism 3. The airbag cushion 33 can effectively absorb these impact forces, reduce the direct collision between the movable rocker arm 31 and the conical cavity, reduce wear, thereby improving the reliability and durability of the system, and reducing maintenance costs and repair frequency.

[0048] As shown above,

[0049] The present invention also provides a control system for the aforementioned traffic warning tunnel marker lights. The control system includes tunnel marker lights 100 installed inside a tunnel body 200, a camera 300, and a control module. The tunnel marker lights 100 are arranged equidistantly along the length of the tunnel body 200. The control module forms a signal connection with all tunnel marker lights 100 to monitor moving vehicles via the camera 300 and manually identify traffic accidents during driving. When a traffic accident occurs, the control module controls the tunnel marker lights 100 above the corresponding lane to illuminate.

[0050] When a car accident occurs, the control module controls the tunnel outline lights 100 above the corresponding lane to light up, and the two adjacent tunnel outline lights 100 in front and behind flash alternately.

[0051] In a preferred technical solution, cameras 300 are respectively arranged above each lane in the tunnel body 200. Each camera 300 and its adjacent monitoring area constitute a monitoring area. There is an intersecting area between the left and right adjacent monitoring areas on the two lanes. Vertically arranged tunnel contour lights 100 are arranged in the intersecting area. When a traffic accident occurs in the monitoring area, all tunnel contour lights 100 in the intersecting area can be controlled.

[0052] A preferred technical solution, wherein, when a traffic accident occurs in a certain monitoring area and the tunnel outline lights 100 above the corresponding lane are illuminated, all tunnel outline lights 100 in the lane will flash alternately from near to far, with the monitoring area where the traffic accident occurred as the center, and the frequency interval of the flashing will gradually increase, with the increase frequency being n+0.5s;

[0053] Wherein, n is the flashing frequency interval time of the monitoring area where the traffic accident occurred, and the flashing frequency interval time is 0.3s.

[0054] Moreover, when a car accident occurs, the control module can be used to control the lamp beads 21 provided on the surface of the tunnel outline light 100 above the corresponding lane to light up, and control the motor 1 22 to lower the warning mechanism 3, and drive the warning mechanism 3 to swing through the transmission structure, so that the reflective sheet provided on the surface of the warning mechanism 3 reflects light, thereby improving the warning effect of the tunnel outline light 100.

[0055] The above description is merely a preferred embodiment of the present invention and therefore cannot be used to limit the scope of the present invention. In other words, equivalent changes and modifications made according to the scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
