摘要
本文针对节能型LED灯具的稳定调光特点,通过洞内外亮度检测仪、毫米波雷达车辆探测器等设备对亮度、交通量、车速等参数的检测结果,计算车辆到来时隧道各照明区段所需亮度,构建丰富隧道照明方式、提高隧道照明效率的智能化照明节能控制系统,实现“车来灯亮,车走灯暗,灯随车行”的自动控制技术,测算并验证了系统的经济效益和节能环境效益。结果表明,所采用的方案在低交通量下的隧道节能效果显著,相比常用的无级调光控制,可降低年运营费用近40%。这不仅加快了公路隧道节能环保技术和照明自适应控制技术推广应用,而且营造了一个科学合理、安全有序的交通环境,对推动公路隧道设计及运营提质升级具有积极的促进作用。
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.
