基于车辆感知和模糊PID的隧道照明控制系统

Tunnel lighting control system based on vehicle perception and fuzzy PID

针对隧道照明的耗电量大,以及隧道内LED灯长时间运行后亮度降低且调光效果变差的问题,设计了一种以"车进灯亮,车走灯灭"为隧道照明的控制策略,模糊比例—积分—微分(PID)控制为调光方式的照明系统。对系统的亮度采集电路、调光控制电路及车辆检测电路进行了设计,完成了相应的软件控制系统。实验结果表明:该系统能稳定运行,且能有效减少光衰现象对照明控制系统的影响,保证行车安全。

Aiming at the problems of large power consumption of tunnel lighting and the decrease of brightness and dimming effect after long-time operation of LED lights in tunnels,a lighting system is designed,which takes " vehicle in,light brightens;vehicle out,light darkens" as the control strategy of tunnel lighting and fuzzy PID control as the dimming mode. Brightness acquisition circuit of the system dimming circuit and vehicle detection circuit are designed,the corresponding software control system is completed. The experimental results show that the system can operate stably and can effectively reduce the impact of light decay on the lighting control system and ensure driving safety.
