高速公路隧道入口智能调光控制方案设计

Design of Intelligent Dimming Control Scheme of Highway Tunnel Entrance

隧道照明是影响隧道安全通行的关键因素,隧道洞内外光照强度差异大容易形成黑洞效应,从而造成隧道内行车安全事故。依据隧道照明的关键质量要素及人眼对光的视觉特性理论,采用L 20法确定隧道洞口亮度,根据洞口环境亮度、天气、车流量、隧道事件变化来设计智能调光控制方案。为隧道安全通行提供照明保障,同时达到环保节能的目的。

Tunnel lighting is the key factor affecting the safe passage of tunnel,and it is easy to form black hole effect for the difference of light intensity inside and outside the tunnel hole,which causes the traffic safety accident in the tunnel.According to the key quality elements of tunnel lighting and the theory of the visual characteristics of human eye-to-light,the brightness of the tunnel hole is determined by L 20 method,and the intelligent dimming control scheme is designed according to the ambient brightness,weather,traffic flow and tunnel event change.For the safe passage of the tunnel to provide lighting protection,while achieving environmental protection and energy-saving purposes.
