Expressway tunnel visual environment improvement device and method thereof

Abstract

The invention discloses an expressway tunnel visual environment improvement device and method thereof. The device comprises an expressway tunnel and a tunnel illumination system. Supporting rods are symmetrically arranged on the two sides of the highway at the entrance and exit end of the expressway tunnel, a light shading plate with an adjustable opening in the upper end is connected to the supporting rods, the light shading plate blocks most sunlight, the other sunlight is emitted into the light shading plate, the light environment inside the light shading plate is changed, according to theintensity of the sunlight, the light shading plate is controlled by a light sensing controller to rotate, the adaptability of the light shading plate under different environments is improved, the vision environment of a driver at the entrance and exit region of the expressway tunnel can be effectively improved, no special illumination lamp needs to be added at the entrance and exit of the tunnel,the influence of the black-hole effect and white-hole effect on travelling safety can be effectively lowered, and the device is simple in structure, high in adaptability, and capable of effectively reducing energy waste and improving the energy-saving performance of the illumination system.

Description

technical field [0001] The invention relates to a device for improving the visual environment of expressway tunnels and an improving method thereof, and belongs to the technical field of expressway tunnel construction equipment. Background technique [0002] With the rapid development of my country's economy, the scale of expressway traffic continues to expand. my country's expressways extend from plains to mountainous areas, from the east to the midwest, and the mileage of bridges and tunnels is also increasing rapidly. Studies have shown that "black hole effect" and "white hole effect" appear at the entrance and exit of the tunnel due to sudden changes in the light environment and physical environment. Vehicles frequently change the driving environment in a short space at the entrance and exit of the tunnel. It is said that the information to be processed is more complicated, and a little carelessness may cause operational errors, which may lead to traffic accidents. At p...

AI Technical Summary

Problems solved by technology

However, the method equipment investment is relatively high. For mountainous areas, due to the influence of geographical environment, the number of expressway tunnels is huge, and the investment in lighting system power supply equipment and lighting electricity consumption are relatively large. In order to control operating costs and reduce Due to maintenance costs and other reasons, the lighting conditions of most road tunnels during the day are not good, resulting in the high incidence of road tunnel accidents still seriously threatening the safety of tunnel traffic
