Phototaxis adaptation system for short-range tunnel

Abstract

The invention discloses a phototaxis adaptation system for a short-range tunnel. The system comprises two resistance rods penetrating through a road surface, wherein the two resistance rods are arranged on the same straight line and are fixedly connected with each other through an insulating layer at positions close to each other, a vision buffering structure is arranged in each resistance plate,the vision buffering structure comprises a first vision buffering lamp, a second vision buffering lamp and a third vision buffering lamp, each first slow vision lamp is located on the outer side of the tunnel, the top of each first slow vision lamp is communicated with two first photoresistors, two second photoresistors are arranged on the outer portion of the end, located in the tunnel, of the resistance rod in a communicating mode, two first photoresistors and two second photoresistors are communicated through a bridge circuit, and a plurality of searchlights are arranged on the inner side of the tunnel. The tunnel lighting system is advantaged in that drivers can adapt to the working environment where the tunnel lighting lamps are bright in advance by arranging the slow vision lamps inthe stepped bright state at the tunnel entrance and exit, and therefore traffic accidents caused by rapid change of light are avoided.

Description

technical field [0001] The invention relates to the technical field of road facilities, in particular to a phototaxis adaptation system for short-distance tunnels. Background technique [0002] Suidao is a cavern with a cross-sectional area greater than 2 square meters built under the ground in accordance with the specified shape and size for a certain purpose, and is generally buried in the ground. It is a kind of engineering building that humans use underground space. Can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, mine tunnels, military tunnels [0003] And when the short-distance tunnel in the prior art is used, generally will not be equipped with illuminating lamp during the day, therefore under the state that the difference of light and darkness inside and outside the tunnel is bigger, when entering the beginning stage and the end stage of the tunnel, due to the sudden light Therefore, when the driver enters and exits the tunnel, the line of...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem in the prior art that the driver will have a short time to adapt when entering and exiting the tunnel, which is likely to cause traffic accidents, and proposes a phototaxis adaptation system for short-distance tunnels
