Research and Application of Accompanying Lighting Control System for Highway Tunnels
Aiming at the stable dimming characteristics of energy-saving LED lamps,this paper calculates the required brightness of each tunnel lighting section when vehicles arrive by using the detection results of brightness detector inside and outside the tunnel,millimeter wave radar vehicle detector and other devices for brightness,traffic volume,speed and other parameters,and builds an intelligent lighting energy-saving control system that enrich tunnel lighting methods and improve tunnel lighting efficiency,the automatic control technology of"light on when the car comes,dark when the car goes,and the light follows the car"is realized,the economic benefits and energy-saving environmental benefits of the system are measured and verified.The results show that the proposed scheme has remarkable energy-saving effect under low traffic volume,and can reduce the annual operating cost by nearly 40％compared with the common stepless dimming control.This not only accelerates the promotion and application of energy-saving environmental protection technology and adaptive lighting control technology in highway tunnels,but also creates a scientific,reasonable,safe and orderly traffic environment,which has a positive role in promoting the quality and upgrading of highway tunnel design and operation.
