摘要
为了解决当前隧道照明系统中存在的耗电量大、隧道外环境值测量复杂、实际照明亮度难以保证以及忽略光源色温会对隧道照明效果产生影响等问题,设计了一种隧道闭环反馈智慧照明系统。该系统根据实时采集的隧道外环境数据、车辆信息,调整隧道内照明状态。同时,配合变色温隧道灯,实现实时调节亮度和色温值,保证隧道内照明视觉效果处于最佳状态。系统采用闭环反馈调节方式,根据所需亮度、色温值,以实际测量亮度、色温值为基础,实时调节照明系统的输出。实验证明,该系统安全可靠,能够保证照明效果达到预期,确保行车安全的同时使驾驶员获得最佳的视觉感受,同时能够最大限度降低能耗。
In order to solve the problems existing in the tunnel lighting system such as large power consumption, complex tunnel outside environment value measure,the actual illumination brightness is difficult to guarantee,and ignore of light source color temperature＇s eft）et on tunnel lighting,a kind of intelligent tunnel closed-loop feedback lighting control system was designed. The system adjusted the lighting condition of the tunnel according to the data of the tunnel environment and vehicle information collected in real time. With the color changing temperature tunnel lamp,the luminance and color temperature could be adjusted at the same time to ensure the best lighting eft）et in the tunnel. The system adopted closed- loop feedback control method,based on the lighting required brightness,color temperature value and the actual measurements of the brightness, color temperature, the output of lighting system was adjusted at the same time. The experiment showed that the system was safe and reliable,and could guarantee the real-time lighting effeet to reach the expected effect. It could guarantee the safety of driving and made the driver get the best visual sense. It also minimized energyd consumption.
