The Design of Tunnel Lighting Intelligent Control System

Abstract

<p class="p0">It is serious that the electric energy waste exists in highway tunnel operation. Operators and institutes of scientific research pay more and more attention that how to reduce the energy consumption of lighting system of highway tunnels, improve the effect of tunnel lighting and ensure traffic safety. In order to solve the problem of the current tunnel lighting system with high energy consumption, a tunnel lighting intelligent control system based on environmental information perception and vehicle behavior information perception is proposed in this paper for ChiBai tunnel project. In this system, the existence of the vehicle or not is the basis of lighting state switching, environmental information and vehicle behavior information are the basis for calculation of the lighting brightness, pavement illuminance is real-time monitored by the monitoring cameras, closed-loop feedback control of the lighting brightness is achieved through real-time monitoring of pavement illuminance and PID algorithm. The intelligent control system is composed of five parts, in this paper, there are detailed introductions about the function of various parts of the system, including hardware structure, connecting method and the system of dimming control strategy, software functions and the equipment layout position.</p>
