Description

Technical Field

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

[0002] When a car accident occurs in a tunnel, due to the narrow road in the tunnel, it is extremely easy to cause congestion of subsequent vehicles. And if the accident occurs at the entrance of the tunnel, due to the rapid change in light brightness, subsequent vehicles cannot timely detect the accident at the tunnel entrance, resulting in rear-end collisions. In existing tunnel warning lights, the brightness is low and the warning area is small, and the brightness in the tunnel is low, so the warning lights cannot be observed in time. Therefore, a warning light with a more eye-catching reminder effect is needed. Summary of the Invention

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

[0004] The technical solution adopted by the present invention to solve its technical problems is: A traffic warning tunnel contour light, the tunnel contour lights are arranged at equal intervals along the length direction of the tunnel. The tunnel contour light includes a fixing plate, a lamp housing, and a warning mechanism installed at the lower end of the lamp housing. The lamp housing is fixed in the tunnel body through the fixing plate; A plurality of lamp beads are arranged on both sides of the lamp housing respectively. The lamp beads are connected in series with each other and emit light when powered on. A motor one for retracting and releasing the warning mechanism is also provided in the lamp housing. The warning mechanism is composed of a plurality of warning plates. Each two adjacent warning plates are connected by a rotating shaft, and the swinging directions of two adjacent warning plates are opposite. A traction rope is wound around the output shaft of the motor one. The traction rope sequentially passes through all the warning plates in an alternating manner and is connected to the surface of the lowermost warning plate. When the motor one rotates the output shaft to wind up the traction rope, it drives each warning plate to swing upward and gather from bottom to top in turn; Reflective sheets are provided on the surfaces of all the warning plates. When the motor one lowers the warning plates, the reflective sheets on all the warning plates are arranged in the same direction.

[0005] In a preferred technical solution, a transmission structure is provided on the side surface of the lamp housing. The warning mechanism is connected to the lamp housing through this transmission structure. The transmission structure includes a power end and a movable end provided 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 sleeved outside the movable end through a fixed shaft, and the movable end protrudes from the left and right sides of the fixed shaft respectively. When the power end works, the power end alternately pushes the surfaces of the movable end protruding from both sides of the fixed shaft, and drives the warning mechanism to swing through the movable end.

[0006] A preferred technical solution is that the transmission structure includes a second motor disposed on the surface of the lamp housing and a push rod. The push rods are symmetrically arranged. Each of the two push rods includes a toothed rod and an eccentric rod. The eccentric rod is connected to the side surface of the toothed rod and is disposed deviating from the center of the toothed rod, and the deviation directions of the two eccentric rods are opposite; The eccentric rods in the two push rods are arranged away from each other, and tooth grooves are provided on the adjacent surfaces of the two toothed rods. A driving gear disk meshing with the toothed rod is provided on the output shaft of the second motor, so as to drive the two toothed rods to rotate through the second motor.

[0007] A preferred technical solution is that the movable end includes a clamping bead and movable swing rods symmetrically arranged on both sides of the clamping bead. The two movable swing rods protrude from the two ends of the fixed shaft and are connected to the surface of the warning mechanism. A spherical cavity and a conical cavity are provided inside the fixed shaft. The conical cavities are symmetrically arranged on the left and right sides of the spherical cavity. The movable swing rods penetrate through the conical cavities and extend out of the ends of the fixed shaft, and there is a movable gap between the movable swing rods and the conical cavities. An airbag pad is filled in the movable gap.

[0008] A control system for a tunnel profile lamp for traffic warning, which is applied to the tunnel profile lamp for traffic warning as described above. The control system is characterized in that the control system includes tunnel profile lamps, cameras and a control module installed inside the tunnel body. The tunnel profile lamps are arranged at equal intervals along the length direction of the tunnel body. The control module forms a signal connection with all the tunnel profile lamps to monitor the vehicles in motion through the cameras and artificially identify traffic accidents during the driving process. When a traffic accident occurs, the control module controls the tunnel profile lamps above the corresponding lane to light up; When a traffic accident occurs and the control module controls the tunnel profile lamps above the corresponding lane to light up, the two adjacent tunnel profile lamps before and after flash alternately.

[0009] A preferred technical solution is that the cameras are respectively arranged above each lane inside the tunnel body. Each camera and its adjacent monitoring area form a monitoring area. There is an overlapping area between the left and right adjacent monitoring areas on two lanes. Vertically arranged tunnel profile lamps are provided in the overlapping area. When a traffic accident occurs in the monitoring area, all the tunnel profile lamps in the overlapping area can be controlled.

[0010] A preferred technical solution is that when a traffic accident occurs in a certain monitoring area and the tunnel profile lamps above the corresponding lane light up, all the tunnel profile lamps in the lane alternate and flash from near to far with the monitoring area where the traffic accident occurs as the center, and the frequency interval time gradually increases, and the increased frequency is n + 0.5 s; Wherein, n is the frequency interval time of the monitoring area where the traffic accident occurs, and the frequency interval time is 0.3 s.

[0011] Compared with the prior art, this technical solution has the following advantages: By lowering the warning mechanism, the present invention effectively solves the problems of low brightness, small warning area of existing tunnel warning lights, and difficulty in being observed in a timely manner in tunnels with relatively dim light. First of all, the reflective monitoring area formed after the warning mechanism is deployed is large, which can significantly improve the warning effect on subsequent vehicles. The design of the reflective sheet enables the reflective monitoring area to be clearly seen even when the vehicle's lights are weak in a tunnel with relatively dim light, so as to discover accidents or other abnormal situations ahead in advance and avoid the occurrence of secondary accidents such as rear-end collisions. Secondly, through the precise control of the first motor, the deployment and retraction process of the warning mechanism is fast and stable, which can quickly activate the warning function in case of emergency, and at the same time retract the warning mechanism under normal circumstances without affecting the normal traffic order in the tunnel.

Specific implementation

[0023] As Figures 1 to 9 Shown, a tunnel contour light for traffic warning is proposed in the present invention, including a tunnel contour light 100 installed inside the tunnel body 200. The tunnel contour lights 100 are arranged at equal intervals along the length direction of the tunnel body 200. The tunnel contour light 100 includes a fixing plate 1, a lamp housing 2, and a warning mechanism 3 installed at the lower end of the lamp housing 2. The lamp housing 2 is fixed in the tunnel body 200 through the fixing plate 1; A plurality of lamp beads 21 are arranged on both sides of the lamp housing 2 respectively. The lamp beads 21 are connected in series with each other and are powered on to emit light. A motor 22 for retracting and releasing the warning mechanism 3 is further provided in the lamp housing 2. The warning mechanism 3 is composed of a plurality of warning plates. Each two adjacent warning plates are connected by a rotating shaft, and the swinging directions of two adjacent warning plates are opposite. A traction rope 23 is wound around the output shaft of the motor 22. The traction rope 23 sequentially passes through all the warning plates in an alternating manner and is connected to the surface of the lowermost warning plate. When the motor 22 rotates the output shaft to wind up the traction rope 23, the warning plates are driven to swing upward and gather in sequence from bottom to top; Reflective sheets are provided on the surfaces of all the warning plates. When the motor 22 lowers the warning plates, the reflective sheets on all the warning plates are arranged in the same direction; In the tunnel contour light of the present invention, the lowering process of the warning mechanism 3 is realized through the precise control of the motor 22. When an accident or other warning situations occur in the tunnel, the control system will send an instruction to the motor 22 to make its output shaft start to rotate. At this time, the output shaft of the motor 22 will release the traction rope 23 wound thereon. The traction rope 23 sequentially passes through all the warning plates in an alternating manner. As the traction rope 23 is gradually released, the warning plates are unfolded from top to bottom in sequence. Since adjacent warning plates are connected by a rotating shaft and the swinging directions are opposite, this design enables the warning plates to form an orderly unfolding state during the unfolding process, similar to the unfolding mode of an accordion. Finally, all the warning plates are completely unfolded, and the reflective sheets on their surfaces are arranged in the same direction, forming a large-area reflective monitoring area.

[0024] By lowering the warning mechanism 3, the present invention effectively solves the problems of low brightness, small warning area of existing tunnel warning lights, and difficulty in being observed in a timely manner in a tunnel with relatively dim light. First of all, the warning mechanism 3 forms a large reflective monitoring area after unfolding, which can significantly improve the warning effect on subsequent vehicles. The design of the reflective sheet enables the reflective monitoring area to be clearly visible even when the vehicle's lights are weak in a tunnel with relatively dim light, so as to discover accidents or other abnormal situations ahead in advance and avoid the occurrence of secondary accidents such as rear-end collisions. Secondly, through the precise control of the first motor 22, the unfolding and retracting processes of the warning mechanism 3 are fast and stable, which can quickly activate the warning function in case of emergency, and at the same time retract the warning mechanism 3 under normal circumstances without affecting the normal traffic order in the tunnel. This automatic control method not only improves the safety of the tunnel, but also reduces the need for manual intervention and improves the management efficiency.

[0025] Traditional tunnel warning lights usually adopt simple light flashing or constant-on modes, with a small warning area and poor visibility of the lights in a tunnel with relatively dim light, making it difficult to attract sufficient attention from subsequent vehicles. Especially at the tunnel entrance where the light changes rapidly, it is easily ignored by drivers. The invention forms a large-area reflective monitoring area by lowering the warning mechanism 3. The design of the reflective sheet enables the monitoring area to produce a strong reflective effect under the illumination of the vehicle's lights, and can be clearly seen by the driver even in a tunnel with relatively dim light. This large-area reflective monitoring area is more eye-catching than a simple light flashing or constant-on mode and can more effectively remind the driver of abnormal situations ahead.

[0026] 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 this transmission structure. The transmission structure includes a power end and a movable end provided on the surface of the lamp housing 2. The movable end is connected to the warning mechanism 3 and is arranged near the central axis of the warning mechanism 3. The lamp housing 2 is sleeved outside 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 works, the power end alternately pushes the surfaces of the movable end protruding from both sides of the fixed shaft 24 and drives the warning mechanism 3 to swing through the movable end.

[0027] Among them, 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. Both push rods 26 include a rack 261 and an eccentric rod 262. The eccentric rod 262 is connected to the side of the rack 261 and is arranged deviating from the center of the rack 261, and the deviation directions of the two eccentric rods 262 are opposite; The eccentric rods 262 within the two push rods 26 are arranged to be away from each other, and tooth grooves are provided on the adjacent surfaces of the two rack bars 261. A driving gear disc 251 meshing with the rack bar 261 is provided on the output shaft of the second motor 25 to drive the two rack bars 261 to rotate through the second motor 25; As can be seen above, the design of the eccentric rod 262 deviating from the center enables it to generate a thrust with a continuously changing direction during rotation. The changing direction of this thrust can more effectively push the movable end, causing it to produce a more obvious swinging effect. Since the deviation directions of the eccentric rods 262 are opposite, the two push rods 26 can cooperate with each other during operation to produce a larger swinging amplitude. This design makes the swinging of the warning mechanism 3 more significant.

[0028] Moreover, the movable end includes a bead 32 and movable swing rods 31 symmetrically arranged on both sides of the bead 32. The two movable swing rods 31 both protrude from the two ends 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 inside the fixed shaft 24. The conical cavity is symmetrically arranged on the left and right sides of the spherical cavity. The movable swing rod 31 passes through the conical cavity and extends out of the end of the fixed shaft 24, and an activity gap is provided between the movable swing rod 31 and the conical cavity. An airbag pad 33 is filled in the activity gap.

[0029] The design of the movable swing rod 31 passing through the conical cavity enables the warning mechanism 3 to obtain a more flexible movement space during swinging. The special shape of the conical cavity provides a guiding function for the movable swing rod 31, ensuring that it can move smoothly along a preset trajectory during swinging, avoiding jamming or irregular swinging caused by structural limitations. This smooth swinging enables 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, enhancing the warning effect on passing vehicles. And in the complex traffic environment in the tunnel, the vibration of the vehicle and the impact of the air flow may have a certain impact on the warning mechanism 3. The airbag pad 33 can effectively absorb these impacts, reduce the direct collision between the movable swing rod 31 and the conical cavity, reduce wear, thereby improving the reliability and durability of the system, and reducing the maintenance cost and repair frequency.

[0030] As shown above, In the present invention, a control system for the tunnel profile lights for traffic warning is also proposed. The control system includes tunnel profile lights 100, cameras 300, and a control module installed on the inner side of the tunnel body 200. The tunnel profile lights 100 are arranged at equal intervals along the length direction of the tunnel body 200. The control module forms a signal connection with all the tunnel profile lights 100 to monitor the passing vehicles through the cameras 300 and artificially identify traffic accidents during driving. When a traffic accident occurs, the control module controls the tunnel profile lights 100 above the corresponding lane to light up; When a car accident occurs and the control module controls the tunnel contour lights 100 above the corresponding lane to light up, the two adjacent tunnel contour lights 100 before and after flash alternately.

[0031] 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 form a monitoring area. There is an overlapping area between the left and right adjacent monitoring areas on two lanes. Vertically arranged tunnel contour lights 100 are arranged in this overlapping area. When a car accident occurs in this monitoring area, all the tunnel contour lights 100 in this overlapping area can be controlled.

[0032] In a preferred technical solution, when a car accident occurs in a certain monitoring area and the tunnel contour lights 100 above the corresponding lane light up, all the tunnel contour lights 100 in this lane alternately flash from near to far with the monitoring area where the car accident occurs as the center, and the frequency interval time gradually increases. The increasing frequency is n + 0.5 s; Wherein, n is the flashing frequency interval time of the monitoring area where the car accident occurs, and this flashing frequency interval time is 0.3 s.

[0033] Moreover, when a car accident occurs, the control module can control the lamp beads 21 arranged on the surface of the tunnel contour lights 100 corresponding to the lane to light up, control the first motor 22 to lower the warning mechanism 3, and drive the warning mechanism 3 to swing through the transmission structure, so that the reflective sheet arranged on the surface of the warning mechanism 3 reflects light, improving the warning effect of the tunnel contour lights 100.

[0034] The above is only a preferred embodiment of the present invention, so the scope of implementation of the present invention cannot be limited thereby. That is, equivalent changes and modifications made according to the scope of the present invention patent and the content of the specification should still fall within the scope covered by the present invention.
