摘　　要：本文阐述了一种自适应隧道节能照明控制系统,其核心思想是"车近灯亮、车过灯灭"及LED隧道灯组亮度自动调节。该系统的控制器核心单元基于FPGA进行设计,控制器对传感器采集到的信息(隧道内外的光照强度、隧道内车辆的通行情况等)进行运算和处理,产生相应的PWM信号去调整其所控制LED隧道灯组的亮度,以解决过度照明或亮度不足的问题,并与其它控制器进行信息交换;后级控制器依据前级发送的控制指令及其传感器检测的实时信号进行运算和处理,实现隧道路段照明的选择性开关及亮度自动调节,达到自适应系统控制之功能。Abstract ： In this article, we design an adaptive tunnel energy-saving lighting control system. This control system includes the following main ideas ： （i） the lights are on when the ear approaches, （ii） the lights are off when the car drives away, and （iii） the brightness of the LED tunnel light groups is controlled automatically. The FPGA technology is employed to design the core unit of the controller in this new adaptive tunnel energy-saving lighting control system. According to the information collected by sensors, such as the intensity of light inside or outside the tunnel, and the traffic situation inside, the controller produces the corresponding PWM signals which control the brightness of the tunnel light groups automatically. At tion with other controllers. Through processing the control the same time, the controller also exchanges informainstruction received from the former controller and the information collected by sensors, the next controller could realize the selective switching and the adaptive brightness to achieve the function of adaptive control.
