摘要
针对目前隧道照明控制常采用分段控制方式,存在过度照明、浪费电力的问题,为降低隧道照明能耗,在LED(Light Emitting Diode)灯具以及无极控制的基础上,依据人眼视觉特性以及交通流状态参数,进行隧道照明设计,并在车辆达到驶离数据的基础上,从行车安全性与节能两方面考虑,采用“车进灯亮,车走灯灭”的控制策略设计了灯具启灭控制方法。经实验验证,所设计的隧道照明连续逐渐变化,更适应于人眼的视觉特性,且该方法可依据交通流数据对隧道灯具进行合理的启灭控制,在保证隧道行车安全的同时降低能耗。
At present, the tunnel lighting control often adopts the method of sectional control, and the lamps are always on, which leads to excessive lighting and waste of power. In order to reduce the energy consumption of tunnel lighting, using LED(Light Emitting Diode) lamps and stepless control, the tunnel lighting design is carried out according to the human visual characteristics and traffic flow state parameters. Based on vehicle arrival and departure data, the control strategy of “vehicle entry light on, vehicle exit light off” is adopted to design the lamp on and off control method from the two aspects of driving safety and energy saving. The experimental results show that the tunnel lighting changes continuously and gradually, which is more suitable for the visual characteristics of human eyes, and the method can reasonably control the on-off of tunnel lamps according to the traffic flow data, so as to ensure the safety of tunnel driving and reduce energy consumption.
