Problems solved by technology

Statistics show that most accidents occur at the exit and entrance of the tunnel. One of the important reasons is that there is a large difference in light intensity between the exit and the entrance of the tunnel. The sudden change of light and dark or the sudden change of light brightness will easily cause the driver to pass through the tunnel. Stimulate the eyes and cause "glare", that is, temporary visual failure; at the same time, the light in the tunnel is all at the same light intensity value, which obviously prolongs the time of dark adaptation and light adaptation, deteriorates the driver's sight distance, and greatly increases the speed of the driver.

Embodiment 1

[0044] The present invention claims to protect an intelligent lighting system for expressway tunnels, including a light sensor group outside the tunnel exit, a light sensor group inside the tunnel exit, a light sensor group in the middle section of the tunnel, a light sensor group inside the tunnel entrance, and a tunnel entrance all connected to the master control module. External light sensor group, several tunnel exit light group controllers, tunnel entrance light group controllers and tunnel middle section light group controllers, and several tunnel exit light group controllers, tunnel entrance light group controllers and tunnel middle section light group controllers correspond Several tunnel exit light groups, tunnel entrance light groups and tunnel middle section light groups controlled;

[0045] The light sensor group outside the tunnel exit is used for real-time monitoring of the light value and changes of the environment outside the tunnel exit, and consists of one or ...

Embodiment 2

[0079] An intelligent lighting device for an expressway tunnel, comprising a tunnel exit illumination information collection unit, a tunnel middle section illumination information collection unit, a tunnel entrance illumination information collection unit, a tunnel exit light group control unit, and a tunnel middle section light information collection unit all connected to a central data processing unit. The control unit and the tunnel entrance light group control unit; the tunnel exit internal light sensor group and the tunnel exit external light sensor group both connected to the tunnel exit light information collection unit; the tunnel entrance light sensor group connected to the tunnel entrance light information collection unit and the light sensor group outside the tunnel entrance; the light sensor group in the middle of the tunnel connected to the light information collection unit in the middle of the tunnel; and several tunnel exits correspondingly controlled by the tunne...

Embodiment 3

[0132] An improved highway tunnel lighting auxiliary device, comprising a tunnel exit inner light sensor, a tunnel exit outer light sensor, a tunnel entrance inner light sensor, a tunnel entrance outer light sensor, a tunnel exit gradient light group controller and a tunnel exit light sensor connected to a control unit. The tunnel entrance gradient light group controller; and the tunnel exit gradient light group controller and the tunnel entrance gradient light group controller correspondingly control several tunnel exit gradient light groups and several tunnel entrance gradient light groups;

[0133] The light sensor outside the tunnel exit is used for real-time monitoring of the light value and changes of the environment outside the tunnel exit, and can be arranged in a corresponding position according to the actual situation;

[0134] The light sensor in the tunnel exit is used for real-time monitoring of the light value and its change within a certain distance in the tunnel...

Abstract

The invention discloses an improved highway tunnel illumination assistant device. According to difference values between the illumination intensity of environments outside an exit and an entrance of atunnel and the illumination intensity in the tunnel, and the changes of the difference values, highway tunnel lamp sets with gradually changed certain distance illumination brightness are arranged inthe exit and the entrance of the tunnel, so that when a driver passes through the tunnel, the eyes can be gradually adaptive to obvious brightness changes inside and outside the tunnel, the time fordark adaptation and light adaptation is shortened, the sight distance of the driver is improved, the irritation of the sudden change of the illumination brightness to the driver is reduced, and the traffic safety of the highway tunnel is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of traffic lighting, in particular to an improved highway tunnel lighting auxiliary device. Background technique [0002] my country is a mountainous country. Nearly two-thirds of the country's total area is mountains, hills and relatively rugged mountainous areas. In these areas, in order to ensure the technical requirements of high-grade highways, tunnels are often used to pass through mountains and ridges. Although highway tunnels have widely used conventional traffic safety signs such as road surface markings, entrance and exit speed limits, height limits, and prohibition of non-motor vehicles; in long tunnels, monitoring, communication, fire protection, ventilation, lighting, etc. Traffic safety facilities; but tunnel traffic accidents are common in recent years. Statistics show that most accidents occur at the exit and entrance of the tunnel. One of the important reasons is that there is a large diffe...
