Description

Technical Field

[0001] The invention relates to the technical field of highway tunnels, in particular to a landscape device for adjacent tunnel openings of a long and narrow tunnel group with a short interval. Background Art

[0002] Highway tunnels are passages designed for automobile transportation. When roads pass through mountainous areas, the previous detours are often replaced by tunnels. The construction of tunnels plays an important role in improving the technical status of highways, shortening operating distances, increasing transportation capacity, and reducing accidents.

[0003] In the construction of mountain highway tunnels, more and more long and large tunnels are beginning to appear. Especially in Yunnan, Guizhou, Sichuan, Guangxi and other regions, there are many mountains and rivers due to the influence of the terrain. It is necessary to cross multiple mountains to build long and large tunnels, and the long and large tunnels are connected by bridges outside the tunnel to form a long and large tunnel group. The space in the tunnel is narrow, and long-distance driving is prone to fatigue, affecting driving safety. In addition, the distance between the mountains between the long and large tunnels is small. Generally, the length of the bridge outside the tunnel is 30m to 40m. Calculated based on the speed limit of 80km / h in the tunnel, the vehicle travels an average of 22 meters per second. Therefore, when a vehicle passes the bridge outside the tunnel, it only has a short time of 1 to 2 seconds. The tunnel is darker and the bridge outside the tunnel is brighter. When a vehicle exits a long tunnel, passes the bridge outside the tunnel and enters another long and large tunnel, there will be a short "dark-bright-dark" light mutation. The driver has no time to adapt to the sudden change of light in a short time, and there will be a short period of visual blindness, which will lead to driving safety problems.

[0004] Therefore, in order to solve the driving safety problem caused by the above light changes. At present, in tunnel design, a sunshade is often set on the top of the bridge outside the tunnel between the two tunnels. This setting alleviates the problem of sudden light changes when driving at the tunnel entrance. However, since the bridge outside the tunnel blocks the light through the sunshade, when the vehicle drives on the bridge outside the tunnel, it is like driving in a tunnel. This makes driving in a long tunnel group like driving in an extra-long tunnel. The driver is in darkness and the same tunnel scene for a long time, which will cause visual fatigue, distraction, and drowsiness, and then induce traffic accidents. Summary of the invention

[0005] The present invention provides a landscape device for adjacent tunnel openings of a long tunnel group to solve the technical problem that the sudden change of light and the sunshade canopy easily cause visual fatigue to the driver when driving in an ultra-long tunnel. The controller and solar power generation device of the prior art are used as reference for the present invention.

[0006] The technical solution adopted by the present invention is: a landscape device for adjacent tunnel openings of a long tunnel group, including a tunnel group, the tunnel group includes a plurality of tunnels, and the adjacent tunnels are connected by bridges outside the tunnels, and also includes:

[0007] The LED screen is arranged on the inner wall of the tunnel where two adjacent tunnels are connected to the bridge outside the tunnel, matching the tunnel and used to provide simulated scenes for the tunnel;

[0008] The bridge outside the tunnel is open.

[0009] Since the traditional tunnel bridge is short, a short sudden change in light will occur when a vehicle passes by. Therefore, the present invention arranges LED screens in the long tunnel on both sides of the tunnel bridge to extend the length of the bright area, thereby increasing the duration of light brightness, reducing the duration of the driver's visual blindness, allowing the driver to gradually adapt to the light change, and avoiding visual fatigue of the driver; the LED screen can play some landscape video images, effectively reducing the driving safety problems caused by sudden changes in light; in addition, the open tunnel bridge also facilitates the discharge of exhaust gas in the tunnel and the entry of fresh air.

[0010] Furthermore, a tunnel expansion section is provided at the entrance where the two adjacent tunnels are connected to the bridge outside the tunnel. The tunnel expansion section is arranged along the longitudinal direction of the tunnel, and the LED screen is arranged in the tunnel expansion section. The surface of the LED screen and the inner wall of the tunnel are located on the same arc surface. The tunnel and the LED screen are integrated to enhance the experience; at the same time, the construction difficulty and construction period are reduced, and the construction cost is saved.

[0011] Furthermore, the LED screen includes:

[0012] Sky segment, used to simulate sky scenes;

[0013] The transition section is used to simulate the scene between the sky and the ground;

[0014] The ground segment is used to simulate the ground scene;

[0015] The sky segment is arranged at the top of the tunnel, the ground segment is arranged at the bottom of both sides of the tunnel, and the transition segment is arranged between the sky segment and the ground segment. The sky segment is connected to the ground segment through the transition segments on both sides. Through the sky segment, transition segment and ground segment, the LED screen in the tunnel can simulate the external environment, greatly enhancing the driver's experience and avoiding excessive differences in the scenes inside and outside the tunnel.

[0016] Furthermore, the central angle range of the sky segment is 85° to 95°, the central angle range of the transition segment is 15° to 25°, and the central angle range of the ground segment is 30° to 35°. From the perspective of the driver in the vehicle, the above angle range can well match the range of the external scene, making it more realistic.

[0017] Furthermore, the center angle of the sky segment is 90°, the center angle of the transition segment is 20°, and the center angle of the ground segment is 32°.

[0018] Furthermore, the mountain surface of the longitudinal section of the tunnel where the sky section, transition section and ground section are located is equipped with light sensors for capturing the real-time scene of the outside world and transmitting the real-time scene to the LED screen. A controller is also provided in the tunnel, which can transmit the real scene outside the tunnel photographed by the light sensor to the LED screen for playback, so as to continue the real-time scene of the outside world at the bridge outside the tunnel, making the scene displayed on the LED screen more coherent, realistic and real-time, and more helpful to reduce the visual fatigue of the driver. The controller technology is a relatively common and mature technology in the prior art.

[0019] Furthermore, the light sensor is a CMOS digital camera, which has the characteristics of good imaging effect, high definition, low cost, low power and the like.

[0020] Furthermore, the total length of the LED screen and the bridge outside the tunnel is 120m to 180m. Based on the speed limit of 80km / h in the tunnel, the vehicle travels 22 meters per second on average. It takes 5 to 8 seconds for the vehicle to pass through the bright area, that is, the LED screen and the bridge outside the tunnel, which is enough for the driver to gradually adapt to the light changes, reduce the driver's visual blindness period, avoid visual fatigue, and improve driving safety; at the same time, it is also out of cost considerations.

[0021] Furthermore, the total length of the LED screen and the bridge outside the tunnel is 150m.

[0022] It also includes a solar power generation device arranged on the bridge outside the cave, and the solar power generation device includes a photovoltaic panel and a battery box, which is used to provide power for the LED screen and the light sensor. Providing power for the LED screen through the solar power generation device is more energy-saving and environmentally friendly. The solar power generation device is also a relatively common and mature technology in the prior art.

[0023] The beneficial effects of the present invention are:

[0024] 1. The present invention arranges LED screens in the long tunnel on both sides of the bridge outside the tunnel to extend the length of the bright area, thereby increasing the duration of light brightness, reducing the driver's visual blindness period, allowing the driver to gradually adapt to light changes, and avoiding driver visual fatigue; the LED screen can play some landscape video images, effectively reducing the driving safety problems caused by sudden changes in light.

[0025] 2. In the present invention, light sensors are provided on the mountain bodies of the longitudinal sections of the tunnels where the sky sections, transition sections and ground sections are located. The real scenes outside the tunnel photographed by the light sensors can be transmitted to the LED screen for playback, which is used to continue the real-time scenery of the outside world at the bridge outside the tunnel, making the scenery displayed on the LED screen more coherent and realistic, which helps to reduce the visual fatigue of the driver and ensure driving safety.
