摘要
隧道照明入口段的长度和亮度直接影响隧道的交通安全,但同时也是隧道照明系统的能耗大户,如何在保证运营安全并营造高速公路隧道良好的驾驶视觉环境的前提下节省能耗是目前隧道照明系统建设运营的重点研究方向。通过探讨与研究公路隧道进口处的减光设计,提出了一种结合智能调光技术的隧道遮阳棚设计,将遮阳棚作为隧道照明入口段,降低了隧道入口处加强照明的能耗。同时运用基于无线物联网技术的智能照明调光技术,解决了在雨雪或者遮阳棚表面附着污物的特殊环境下遮阳棚段路面亮度不足的问题。此外基于无线物联网技术的智能照明调光技术还为解决目前照明区段的分界处亮度突变以及有线调光信号会被湮灭的问题提供了方案。该隧道遮阳棚设计方案在满足隧道行车安全的设计要求下,可降低隧道照明入口段能耗,为今后公路隧道的节能减排提供参考。
The length and brightness of the tunnel lighting entrance section directly affect the traffic safety of the tunnel, where is also a large energy consumer of the tunnel lighting system. How to save energy consumption on the premise of ensuring operation safety and creating a good driving visual environment of expressway tunnel is the key research direction of the construction and operation of tunnel lighting system at present. By discussing and studying the dimming design at the entrance of highway tunnel, in this paper a tunnel sunshade design combined with intelligent dimming technology is put forward. The sunshade is used as the entrance section of tunnel lighting, which reduces the energy consumption of strengthening lighting at the entrance of tunnel. At the same time, the intelligent lighting dimming technology based on wireless Internet of Things technology is used to solve the problem of insufficient pavement brightness in the sunshade section under the special environment of rain, snow or dirt attached to the sunshade surface. In addition, the intelligent lighting dimming technology based on wireless Internet of Things technology also provides a scheme to solve the problems of sudden brightness change at the boundary of lighting section and the annihilation of wired dimming signal. Under the condition of meeting the design requirements of tunnel driving safety, the tunnel sunshade design scheme can reduce the energy consumption of tunnel lighting entrance section, and provide a reference for energy conservation and emission reduction of highway tunnel in the future.
