Description

Technical Field

[0001] The utility model belongs to the technical field of highway traffic safety, and in particular relates to an adaptive tunnel opening shading system based on light intensity. Background Art

[0002] In the operation of traffic tunnels, driving safety and visual comfort have always been one of the key and difficult points of tunnel construction. On a sunny day, when a driver enters the tunnel entrance, due to the huge difference in brightness inside and outside the tunnel, the driver's eyes need a certain amount of adaptation time to see the situation inside the tunnel clearly; similarly, when the driver exits the tunnel, it also takes a period of time to adapt to the changes in brightness inside and outside, which is the so-called "black hole" and "white hole" effect. When the vehicle speed is high, the "black hole" and "white hole" effects can easily lead to a decrease in the driver's visual function and insufficient reaction time, which can easily induce traffic accidents.

[0003] In order to reduce the black hole and white hole effects, researchers and engineers at home and abroad have adopted measures such as setting up shading (sun) grilles, shading (sun) sheds, and strengthening the lighting at the entrance. Shading grilles are generally hollow designs, and certain light and dark areas will be formed under strong light on sunny days. In addition, in rainy and snowy weather, the effect of blocking rain and snow is poor. A sunshade is a shed-like structure with a closed top structure. It uses the light transmission effect of transparent or translucent materials to achieve a light reduction effect and does not allow sunlight to be projected directly onto the road surface. However, the sunshade will cause unstable light reduction effects due to changes in external weather conditions. At the same time, the maintenance workload during operation is large, and it is not conducive to ventilation in the tunnel, and the number of fans needs to be increased. Strengthening the lighting at the entrance uses a large number of artificial lighting to increase light to make up for the light difference, but this light supplement method is difficult to adjust the brightness according to the external light intensity. At the same time, continuous artificial lighting will greatly waste electricity and greatly increase the operating cost of the tunnel. Utility Model Content
