公路隧道照明控制系统研究与实现

Study on Lighting Control System of the Tunnel on Expressway

隧道照明控制系统在达到基本的照明指标后,安全、舒适又节能的照明技术永远是系统追求的目标。将西汉高速公路铁炉沟隧道照明系统分为基于照明回路控制的手动模式,可以提高系统的安全性;基于五个照明等级控制的分段时序控制模式能够满足不同季节、不同时段的照明要求;基于电路回路控制的自动控制模式不仅能使洞内的照明亮度与外界自然光的亮度相适应,而且节约电能;建议后期采用的基于动态调光的自动控制模式,不仅更好的节约电能,而且提供了舒适的照明,通过一年多的运行证明了其技术方案的可行性。

When the tunnel illuminating control system has achieved its basic illumination indexes, the illuminating technology with safety, comfort, and economy of energy becomes the always aim of the system. The illuminating control system of Tie Lugou tunnel on Xi＇an-Hanzhong expressway be divided into manual control pattern based on circuit control can improve the safety of the system. The illuminating control strategy based on five level time sequence can adapt different season and time. The automatic strategy based on circuit control not only can accommodate the lightness in the tunnel to the nature light outside but also can save power. We ad- vises to adopt the automatic control strategy based on dynamic dimming technique, this scheme can saving power and achieving more comfortable effect. The feasibility of the proposed technique scheme has been demonstrated after running for one year.
