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

[0043] Such as figure 1 As shown, the present invention claims to protect an intelligent lighting system for expressway tunnels, including a group of light sensors outside the tunnel exit, a group of light sensors inside the tunnel exit, a group of light sensors in the middle of the tunnel, and a group of light sensors inside the tunnel entrance, all of which are connected to the master control module. , tunnel entrance 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 Several tunnel exit light groups, tunnel entrance light groups and tunnel middle section light groups correspondingly controlled by the controller;

[0044] The light sensor group outside the tunnel exit is used for real-time monitoring of the light value and cha...

Embodiment 2

[0078] 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

[0131] 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;

Abstract

The invention discloses an intelligent lighting system and method of an expressway tunnel. The lighting brightness of a lamp group in the expressway tunnel can be intelligently controlled in real timeaccording to actual illumination and change condition of an outlet and inlet environment of the tunnel, an eye can be gradually applicable to brightness change inside and outside the tunnel, the timeof dark applicability and bight applicability is shortened, the visual distance of a driver is improved, the stimulation of abrupt change of illumination brightness on the driver is reduced, and thetraffic safety of the expressway tunnel is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of traffic lighting, in particular to an intelligent lighting system and method for expressway tunnels. technical background [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...
