摘要
介绍了一种基于本地控制器STM32的隧道照明自动控制系统设计,主要阐述了系统总体结构,给出了采集单元和驱动单元的硬件结构,对隧道照明自动控制系统的整体控制进行了软件说明。提出隧道照明自动控制系统能根据隧道口的光照亮度、车流量和车速等参数来合理地调节隧道内的照明亮度,从而让驾驶员安全地通过隧道。
This paper introduced the design of tunnel lighting automatic control system based on local controller STM32. The overall structure of the tunnel lighting automatic control system was elaborated. The hardware connection diagram of acquisition unit and drive unit was given,and the overall system control software was described. It is pointed out that the tunnel lighting automatic control system reasonably adjusts the lighting brightness of tunnel according to the light brightness,traffic flow and car speed of tunnel portal,so the drivers safely pass the tunnel.
