摘要
针对我国目前公路隧道照明控制系统存在的行车安全以及电能浪费等问题,本文提出一种公路隧道照明自动控制方案,实现了公路隧道内亮度的连续调光。介绍控制系统的主要组成结构及各部分的功能,设计了照明系统的控制模型及系统主程序控制流程,构建一天时间内隧道照明功率变化模型,模拟现场环境测试与计算的理论值比较,表明该技术满足规范要求并具有显著的节能效果。
Tunnel lighting system is very important in tunnelelectrical engineering. With the consideration of problems such asdriving safety and energy consumption existed in tunnel lighting controlsystem at present, an automatic control system of tunnel lighting basedon stepless control method was presented, and continuous light tuningof LED （light-emitting diode） lamp was achieved. The automaticcontrol system was composed of vehicle detectors, luminance detectors,data converters, lighting control computer, dimming controllersand LED lamps. The tunnel lighting control model was establishedbased on “Specifications for Design of Ventilation and Lighting ofHighway Tunnel （China）” and the flow chart of main procedures ofthe automatic control system was given. Comparison between resultsof simulation experiments in MATLAB and data collected on siteshows that the automatic control system can meet the actual luminancerequirements in tunnel lighting and has good effect on energy-saving.
