公路隧道照明智能控制系统的研究与设计

摘要

针对目前隧道存在的能源浪费问题,提出了一种节能型实时隧道照明控制系统.该控制系统是以STM32微控制器为平台搭建的嵌入式控制系统,系统能够自动采集洞外亮度、车速及车流量等信息,并经过分析计算后下达调光指令,最终由LED驱动模块通过PWM方式对LED灯具进行实时按需调光,可进一步地降低系统能耗,提高隧道的运营管理效益,在实际中具有一定的推广价值.%Aiming at the existing energy waste problems of the tunnel, this paper proposes a real-time tunnel lighting energy-saving control system.The control system is an embedded control system based on STM32, which can automatically collect information such as hole brightness, Vehicles speed and vehicle volume.Then, the dimmer instruction is given after information analysis.Finally, LED lamps dimming is completed real-time through PWM by LED driver module.The system can further reduce the energy consumption and improve the efficiency of the tunnel operation management and it is worthwhile to be popularized.
