Description

Technical Field

[0001] The utility model relates to the field of traffic signal lights, in particular to a traffic signal light and a road condition bidirectional monitoring device. Background Art

[0002] In traditional traffic monitoring systems, traffic lights and surveillance cameras are usually installed in groups and facing each other. That is, the camera on the opposite side of the intersection captures the vehicles at the intersection and the corresponding traffic light conditions of the vehicles. When a vehicle commits a traffic violation such as running a red light, the camera on the opposite side can simultaneously capture the red state of the traffic light and the license plate number at the rear of the vehicle that ran the red light.

[0003] However, this design has certain shortcomings at T-shaped intersections where pedestrians need to be given way. The particularity of T-shaped intersections is that in the straight main road away from the branch road, if there are no pedestrians, continuing to go straight will not affect vehicles in other lanes. However, in order to avoid incidents of not giving way to pedestrians, in reality, this road is often included in the traffic light system equally, that is, regardless of whether there are pedestrians, it is necessary to wait for the traffic light. This idling waiting for the traffic light is meaningless and is not conducive to green environmental protection. For this reason, some intersections set the road to red light, and when there are no pedestrians, straight-moving vehicles can still pass normally (or the straight-moving light is set to be always on yellow), in the hope that straight-moving vehicles will give way when there are pedestrians, and pass normally when there are no pedestrians.

[0004] However, due to the particularity of the intersection, the traffic lights at T-shaped intersections are often set on both sides of the main road rather than in the middle. To capture the situation of vehicles giving way to pedestrians on the straight road on the side of the main road away from the branch road, a camera located on the side of the branch road is required to simultaneously capture the status of the traffic light and the situation of vehicles giving way to pedestrians. This results in the camera's field of view being blocked to varying degrees when a large truck turns right from the branch road or an oncoming large truck passes straight, resulting in some situations of not giving way to pedestrians not being captured. This not only affects the safety of pedestrians, but also makes it difficult to supervise vehicles that do not comply with traffic rules.

[0005] Therefore, in response to the special needs of T-intersections and the shortcomings of existing technologies, a traffic light monitoring device with an integrated two-way camera was developed. The device can monitor the working status of traffic lights in real time and provide unobstructed monitoring records of vehicles giving way to pedestrians, providing more accurate and comprehensive data support for traffic management departments, thereby effectively improving traffic management efficiency and road safety levels. Summary of the invention

[0006] The embodiment of the present application provides a two-way monitoring device for traffic lights and road conditions, thereby solving the problem in the prior art that the viewing angle of the camera at a T-junction may be blocked to varying degrees, resulting in some situations of impoliteness to pedestrians not being captured, thus affecting pedestrian safety and making traffic supervision difficult.

[0007] An embodiment of the present application provides a two-way monitoring device for traffic lights and road conditions, including a traffic light, wherein the traffic light includes a brim and a traffic light, the brim is fixed above the traffic light, a two-way camera is fixed at the front lower end of the brim, the two-way camera includes a first camera and a second camera, the first camera is used to monitor the operation of the traffic light, and the second camera is used to monitor the situation of vehicles giving way to pedestrians.

[0008] As some embodiments of the present application, the traffic light is installed at an intersection with a zebra crossing.

[0009] As a preference of some embodiments of the present application, the traffic light is arranged at a T-shaped intersection with a zebra crossing, and is located on the side of the main road away from the branch road at the T-shaped intersection.

[0010] As some embodiments of the present application, the two-way camera also includes a mounting bracket, and the two-way camera is fixedly mounted on the lower front end of the hat brim through the mounting bracket.

[0011] As some embodiments of the present application, the traffic light also includes a pedestrian indicator light for guiding pedestrians to cross the road.

[0012] Some embodiments of the present application further include a clamping mechanism, which includes an upper clamping plate, a lower clamping plate and a mounting portion, wherein the upper clamping plate and the lower clamping plate work together to clamp the upper and lower ends of the brim, and the mounting portion is fixed to the lower end of the lower clamping plate for fixing the mounting bracket.

[0013] As some embodiments of the present application, the clamping mechanism also includes an anti-slip portion, which is arranged at the upper end of the lower clamping plate and contacts the lower end surface of the brim.

[0014] As some embodiments of the present application, the clamping mechanism also includes a photovoltaic panel, which is arranged at the upper end of the upper clamping plate and is used to convert solar energy into electrical energy for use by the two-way camera.

[0015] As some embodiments of the present application, the side of the upper clamping plate is also provided with a bent edge for preventing the clamping mechanism from moving left and right.

[0016] As some embodiments of the present application, the mounting bracket further includes an extension rod, and the extension rod is threadedly fixedly connected to the mounting portion.

[0017] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0018] By setting the two-way camera at the lower front end of the traffic light brim, it can monitor the operation of the traffic light and the vehicles giving way to pedestrians at the same time. The monitoring process is carried out independently. At the same time, because the zebra crossing in its shooting angle of view is closer than the vehicle to be photographed, that is, it is photographed from the front of the vehicle, the pedestrians in its field of view are no longer affected by vehicles in other lanes, avoiding the situation where large trucks will block pedestrians or vehicles when shooting in the opposite direction, providing more accurate and comprehensive data support for traffic management departments, thereby effectively improving traffic management efficiency and road safety levels.

[0026] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] Embodiment 1: A traffic light and road condition two-way monitoring device, such as Figure 2 , Figure 3As shown, it includes a traffic light 1, which includes a brim 11 and a traffic light 12. The brim 11 is fixed above the traffic light 12, and a two-way camera 2 is fixed at the lower front end of the brim 11. The two-way camera 2 includes a first camera 22 and a second camera 23. The first camera 22 is used to monitor the operation of the traffic light 12, and the second camera 23 is used to monitor the situation of vehicles giving way to pedestrians.

[0028] By setting the two-way camera 2 at the lower front end of the brim 11 of the traffic light 1, it can simultaneously monitor the operation of the traffic light and the vehicles giving way to pedestrians. The monitoring process is carried out independently and is no longer affected by vehicles in other lanes, thereby effectively improving traffic management efficiency and road safety levels.

[0029] Example 2: Figure 1 As shown, in this embodiment, the traffic light and the road condition two-way monitoring device in Embodiment 1 are arranged at a T-shaped intersection 5 with a zebra crossing 4 , and are located on the side of the main road 51 of the T-shaped intersection 5 away from the branch road 52 .

[0030] On the road on the side of the main road 51 away from the branch road 52, when the traffic light 12 is in the red light state and there are no pedestrians who need to cross the zebra crossing 4 controlled by the traffic light 1, vehicles going straight on the road can still pass normally, and vehicles turning right need to stop and wait. When pedestrians need to pass, vehicles on the straight road are required to give way to pedestrians. For those who do not give way to pedestrians, the second camera 23 will take a picture of the person who does not give way to pedestrians, and at the same time, the first camera 22 will take a picture of the red light state of the traffic light at this time, providing evidence for the traffic police to punish the relevant vehicles.

[0031] Since the zebra crossing 4 in its shooting angle of view is closer than the vehicle to be photographed, that is, it is photographed from the front of the vehicle, pedestrians will not be blocked by the vehicle in its angle of view, thus avoiding the situation where large vehicles block pedestrians or vehicles when shooting from the opposite direction, providing more accurate and comprehensive data support for traffic management departments, thereby effectively improving traffic management efficiency and road safety levels.

[0032] Example 3: Figures 3 to 6 As shown, this embodiment is a further development and optimization of the two-way monitoring device for traffic lights and road conditions based on Embodiment 1, wherein the two-way camera 2 also includes a mounting bracket 21, and the two-way camera 2 is fixedly mounted on the lower front end of the brim 11 through the mounting bracket 21.

[0033] The traffic signal light 1 further comprises a pedestrian indicator light 13 for guiding pedestrians to cross the road.

[0034] It also includes a clamping mechanism 3, which includes an upper clamping plate 31, a lower clamping plate 32 and a mounting portion 33. The upper clamping plate 31 and the lower clamping plate 32 work together to clamp the upper and lower ends of the brim 11. The mounting portion 33 is fixed to the lower end of the lower clamping plate 32 for fixing the mounting bracket 21.

[0035] The clamping mechanism 3 further includes an anti-slip portion 34 , which is disposed at the upper end of the lower clamping plate 32 and contacts the lower end surface of the brim 11 .

[0036] The clamping mechanism 3 also includes a photovoltaic panel 35 , which is disposed on the upper end of the upper clamping plate 31 and is used to convert solar energy into electrical energy for use by the two-way camera 2 .

[0037] The upper clamping plate 31 is also provided with a bent edge 311 on its side to prevent the clamping mechanism 3 from moving left and right.

[0038] The mounting bracket 21 further includes an extension rod 211 , and the extension rod 211 is threadedly fixedly connected to the mounting portion 33 .

[0039] The setting of the clamping mechanism 3 is conducive to improving the processing cost of the traffic light and road condition two-way monitoring device, so that the clamping mechanism 3 can be directly installed on the brim 11 of the existing traffic light 1 to form the scheme of the present invention conveniently and quickly, and the setting of the mounting portion 33 can facilitate the disassembly and adjustment of the two-way camera 2, and the setting of the bent edge 311 and the anti-slip portion 34 can make the two-way camera 2 firmly fixed on the brim 11 to prevent the position of the two-way camera 2 from changing due to daily wind and sun exposure. The setting of the extension rod 211 is conducive to adjusting the height of the two-way camera 2, so that it can shoot at a better height and angle to avoid overexposure. The setting of the photovoltaic panel 35 is conducive to improving the energy-saving effect of the device.
