基于电力线载波的隧道LED照明控制系统研究

公路隧道照明的目的是把必要的视觉辨析信息传递给驾驶员，确保车辆在白天或夜间行驶时，能够安全地接近、穿越和通过隧道，防止因视觉辨析信息不足而出现交通事故。隧道LED照明控制系统是基于LED灯能瞬间启动并调整亮度的电气特性，并综合考虑高速公路隧道内环境亮度、车流量等因素，采用电力线载波通信技术实现对LED进行亮度调节。结果表明：将LED隧道灯与稳定可靠的LED隧道灯照明控制系统相结合意义重大，节能降耗效果显著。

Research on Tunnel LED Lighting Control System Based on Power Line Carrier

The purpose of highway tunnel lighting is to transfer necessary visual discrimination information to drivers to ensure that vehicles can safely approach and pass through tunnel when driving in daytime or nighttime to prevent traffic accidents due to insufficience visual discrimination information. The tunnel LED lighting control system realizes adjustment of LED brightness by means of power line carrier based on the electric property the the LED lamps can start and adjust brightness instantaneously and in comprehensive consideration of factors such as environmental brightness and vehicle flow, etc. In expressay tunnel. The result shows that integrating the LED tunnel lamps with stable and reliable LED tunnel lighting control system is of great significance and exhibits remarkable energy saving and consumption reducing effects.
