DU Guanfeng, QIN Huibin. Tunnel lighting control system based on vehicle perception and fuzzy PID[J]. 2021, (2): 95-97+101. DOI: 10.13873/J.1000-9787(2021)02-0095-03.
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.
